This year elections are taking place across the globe, covering almost half of the world’s population. It is also likely to be, yet again, the hottest year recorded as the climate crisis intensifies. The Guardian asked young climate activists around the world what they want from the elections and whether politics is working in the fight to halt global heating.

Climate scientists have told the Guardian they expect catastrophic levels of global heating. Here’s what that would mean for the planet

Exclusive: Survey of hundreds of experts reveals harrowing picture of future, but they warn climate fight must not be abandoned

Exclusive: Planet is headed for at least 2.5C of heating with disastrous results for humanity, poll of hundreds of scientists finds

Outgoing special rapporteur David Boyd says ‘there’s something wrong with our brains that we can’t understand how grave this is’

Cost of environmental damage will be six times higher than price of limiting global heating to 2C, study finds

L’atome a le vent en poupe ? Peut-être mais cela reste à prouver. Selon le dernier rapport World Nuclear Industry Status Report, le nucléaire est désormais un marché de niche, dominé par deux pays.

You would think that we have more than sufficient troubles caused by global warming, pollution, resource depletion, biodiversity loss, ecosystem disruption and a few more. But there is a problem that’s not directly related to the natural world, but by a purely human construction: the financial market. Here is a discussion by Ian Schindler — maître de conference émérite (emeritus professor of mathematics) at the University of Toulouse 1, France, who proposes that we are close to a financial collapse.

In the UK and around the world, those who challenge rich corporations are being hounded and crushed with ever-more inventive penalties, says Guardian columnist George Monbiot

Belangrijkste les van het Wereld Economisch Forum? De klimaatproblematiek en het verlies aan natuur zijn een enorme bedreiging voor de bedrijfswereld. Heel wat CEO’s zijn zich daar intussen van bewust, maar de politiek moet nu het juiste kader scheppen, schrijft Julie Vandenberghe van WWF-België.

This report written by the World Economic Forum, in collaboration with Oliver Wyman, provides an in-depth economic analysis of how climate change will reshape health landscapes over the next two decades. It highlights increased risks from new pathogens, pollution and extreme weather events and shows how these will exacerbate current health inequities, disproportionately impacting the most vulnerable populations.

Climate records tumbled "like dominoes" in 2023, with temperatures far above any recorded level.

Als we binnen de grenzen van onze planeet streven naar welzijn voor iedereen, moeten we dringend nadenken over de manier waarop we onze grondstoffen en natuurlijke bronnen waarderen. Dat schrijft Mathias Schluep, algemeen directeur van het World Resources Forum.

Une longue file d'attente qui serpente à l'entrée du site, aux portes du désert: la dure réalité de la popularité des COP s'est imposée aux dizaines de milliers de délégués, observateurs et journalistes accrédités à la COP28 de Dubaï.

The effect of increasing the concentration of atmospheric carbon dioxide (CO2) on global average surface air temperature might be expected to be constant, but this is not the case. A study published in the journal Science shows that carbon dioxide becomes a more potent greenhouse gas as more is released into the atmosphere.

Without a phase out of fossil fuels, by 2100, 1 in 12 hospitals worldwide will be at high risk of total or partial shutdown from extreme weather events — a total of 16,245 hospitals. Without a phase out of fossil fuels, all of these 16,245 hospitals will require adaptation, where suitable. Even with this enormous investment, for many, relocation will be the only option.

L’équipe STEEP de l’INRIA Grenoble a pris l’initiative de populariser les questions que nous posent aujourd’hui le rapport The limits to growth et le modèle World3 issus de la commande du club de Rome à Dennis et Donella Meadows et leur équipe du MIT en 1972. Alors que 50 ans se sont écoulés depuis sa publication, nous avons constaté que peu de personnes du grand public, mais aussi de collègues en SHS, mais aussi parfois en sciences dures, connaissaient effectivement ce moment important de la pensée systémique sur les questions de modèle de croissance engageant des modes de vie. Son titre alors que nous devons faire face à une crise majeure liée à la non prise en compte des limites planétaires pointées pourtant dans ce rapport, mais aussi en amont, nous oblige.

After 50 years, there is still an ongoing debate about the Limits to Growth (LtG) study. This paper recalibrates the 2005 World3-03 model. The input parameters are changed to better match empirical data on world development. An iterative method is used to compute and optimize different parameter sets. This improved parameter set results in a World3 simulation that shows the same overshoot and collapse mode in the coming decade as the original business as usual scenario of the LtG standard run. The main effect of the recalibration update is to raise the peaks of most variables and move them a few years into the future. The parameters with the largest relative changes are those related to industrial capital lifetime, pollution transmission delay, and urban-industrial land development time.

the starkest warning yet that human activity is pushing Earth into a climate crisis that could threaten the lives of up to 6 billion people this century, stating candidly: “We are afraid of the uncharted territory that we have now entered.” Writing in the journal Biosciences, the coalition of 12 researchers, spanning North America, Europe and Asia, state in unusually stark language: “As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023.”

Earth just had the hottest September on record – and by a record-breaking margin, according to leading international datasets which are used by the World Meteorological Organization (WMO) for its State of the Global Climate monitoring reports.

In the past two years Les Soulèvements de la Terre, a network of ecological activists and groups, has used direct confrontations with polluters and developers to threaten industrial agriculture’s monopoly on the French countryside.

De son côté, le prince Abdulaziz bin Salman, ministre saoudien de l'énergie, a tenté de saper les dernières prévisions de l'Agence internationale de l'énergie selon lesquelles la demande mondiale de combustibles fossiles atteindrait le Pic Oil d’ici à 2030, alors que les énergies renouvelables, moins chères et plus propres, augmentent rapidement. Il est clair que si l’AIE annonce un pic oil, certains pays vont réfléchir à deux fois à continuer dans le pétrole et les investisseurs vont se gratter la tête.

The world’s first study of the increase in pollution from landscape fires across the globe over the past two decades reveals that over 2 billion people are exposed to at least one day of potentially health-impacting environmental hazard annually – a figure that has increased by 6.8 per cent in the last ten years.

Previously, anthropogenic ecological overshoot has been identified as a fundamental cause of the myriad symptoms we see around the globe today from biodiversity loss and ocean acidification to the disturbing rise in novel entities and climate change. In the present paper, we have examined this more deeply, and explore the behavioural drivers of overshoot, providing evidence that overshoot is itself a symptom of a deeper, more subversive modern crisis of human behaviour. We work to name and frame this crisis as ‘the Human Behavioural Crisis’ and propose the crisis be recognised globally as a critical intervention point for tackling ecological overshoot. We demonstrate how current interventions are largely physical, resource intensive, slow-moving and focused on addressing the symptoms of ecological overshoot (such as climate change) rather than the distal cause (maladaptive behaviours). We argue that even in the best-case scenarios, symptom-level interventions are unlikely to avoid catastrophe or achieve more

If you've ever seen the movie Soylent Green, you know it's not about cannibalism. It's about the banality of social collapse. It's not quick. It's a slow burn. Nobody shows any sense of urgency about anything. Everyone still watches talk shows, even if they have to pedal a bike to generate electricity for their television. Nobody under 50 remembers anything better. Here's the plot twist: It's not that corporations are using people as the main ingredient in everyone's favorite new food. It's

Bonn and Geneva, 6 September 2023 (ECMWF and WMO) - Earth just had its hottest three months on record, according to the European Union-funded Copernicus Climate Change Service (C3S) implemented by ECMWF. Global sea surface temperatures are at unprecedented highs for the third consecutive month and Antarctic sea ice extent remains at a record low for the time of year.

Comme l'a expliqué Mme Von der Leyen, les États membres de l'UE devront faire des contributions complémentaires au budget de l'UE, à hauteur de 66 milliards d'euros au total. il se retrouve aujourd’hui pratiquement sans financement, en raison de l’aide « somptueuse » accordée à l’Ukraine. La Commission ne dispose plus que de tout juste 82,5 milliards d’euros. Des clopinettes ! Le programme vert devrait donc disparaître de la scène politique.

The UN Secretary-General’s Early Warnings for All Initiative (EW4All) is rapidly gaining ground. Action plans are being rolled out around the world to ensure that people know when dangerous weather is headed their way. Tajikistan has held a two-day national consultation, co-chaired by the Deputy Prime Minister and the UN Resident Coordinator in Tajikistan, and bringing together key stakeholders from state and international organizations, media and civil society. Ethiopia also held an inception workshop.

New data on WRI's Aqueduct platform ranks the world's most water-stressed countries. One-quarter of the global population regularly use up their entire water supply.

Homo sapiens has evolved to reproduce exponentially, expand geographically, and consume all available resources. For most of humanity’s evolutionary history, such expansionist tendencies have been countered by negative feedback. However, the scientific revolution and the use of fossil fuels reduced many forms of negative feedback, enabling us to realize our full potential for exponential growth. This natural capacity is being reinforced by growth-oriented neoliberal economics—nurture complements nature. Problem: the human enterprise is a ‘dissipative structure’ and sub-system of the ecosphere—it can grow and maintain itself only by consuming and dissipating available energy and resources extracted from its host system, the ecosphere, and discharging waste back into its host. The population increase from one to eight billion, and >100-fold expansion of real GWP in just two centuries on a finite planet, has thus propelled modern techno-industrial society into a state of advanced overshoot. We are consuming and

According to ERA5 data from the EU-funded Copernicus Climate Change Service (C3S), the first three weeks of July have been the warmest three-week period on record and the month is on track to be the hottest July and the hottest month on record. These temperatures have been related to heatwaves in large parts of North America, Asia and Europe, which along with wildfires in countries including Canada and Greece, have had major impacts on people’s health, the environment and economies.

De extreme hittegolven deze maand in grote delen van de VS, Zuid-Europa en China zouden ‘vrijwel onmogelijk’ geweest zijn zonder de door de mens veroorzaakte klimaatverandering. Dat is de conclusie van het World Weather Attribution-initiatief (WWA).

The method used to conduct an attribution study consists of eight steps, described here. The first step is the selection of an extreme event to study. After selecting an extreme weather event to study, the first step is to define the event, which provides a framework for the study. Researchers determine the geographical boundaries of the most impacted area, the best index to quantify the meteorological extreme (eg. maximum temperature, average rainfall, etc), and the duration of the event.

Following a record hot June, large areas of the US and Mexico, Southern Europe and China experienced extreme heat in July 2023, breaking many local high temperature records.

The Energy Institute is, as of 2023, the home of the Statistical Review of World Energy, published previously for more than 70 years by bp. The Statistical Review analyses data on world energy markets from the prior year. It has been providing timely, comprehensive and objective data to the energy community since 1952.

Without more legally binding and well-planned net-zero policies, the world is highly likely to miss key climate targets.

A major reason for the growth in the use of renewable energy is the fact that if a person looks at them narrowly enough--such as by using a model--wind and solar look to be useful. They don't burn fossil fuels, so it appears that they might be helpful to the environment. Energy modeling misses important points. I believe that profitability signals are much more important.

La CSRD, dont les standards sont en discussion en ce moment dans les instances européennes, pourrait être finalement vidée de sa substance et de son ambition. Le texte, qui représentait un progrès significatif en matière d’obligations RSE et notamment d’obligation de reporting, est en ce moment l’objet d’une opposition vigoureuse des groupes d’intérêt et des lobbies, qui tentent d’affaiblir le texte. Alors, est-ce la fin annoncée de ce texte pourtant fondateur pour la responsabilité des entreprises opérant en Europe ? Revenons sur les dernières évolutions des discussions autour de la CSRD.

WMO's annual State of the Climate in Europe report explores changes in climate indicators, extreme events and climate policy.

Inégalités environnementales et inégalités sociales sont deux facettes d’une même crise : celle de notre système économique. Les plus pauvres sont les plus touchés par la crise climatique, et la précarité verrouille souvent la transition écologique. Voilà pourquoi la transition doit être écologique, mais aussi sociale.

Dans trente ans, la population mondiale avoisinera les 9,7 milliards d'habitants. Deux tiers de ces personnes vivront dans des zones urbaines densément peuplées et la planète connaîtra un boom de la construction sans précédent.

Eco-fascism, for the uninitiated, is best known as the ideology embraced by the mass shooter who killed 10 people in a Buffalo supermarket last year. The shooter, as E&E News reported at the time, was motivated by “the racist conspiracy theory that the ruling class is using immigration to politically and culturally ‘replace’ white people.” The Buffalo shooter called on others “to view immigration as ‘environmental warfare,’” and to “reclaim environmentalism in the name of white nationalism.” His calls echoed those of the mass shooter who killed 23 people in an El Paso, Texas Walmart in 2019, who was also a self-proclaimed eco-fascist.

The sharp rise in fossil fuel subsidies is just one example of why activists say climate treaties are so often meaningless.

Helaas is de World Social Justice Day van de Verenigde Naties van vandaag 20 februari een bittere ervaring voor meer dan 1,5 miljoen Belgen die op of onder de armoedegrens leven”, aldus algemeen coördinator Heidi Degerickx van het Netwerk tegen Armoede (Cijfers Statbel). Het Netwerk stelt samen met de 61 verenigingen waar mensen in armoede het woord nemen vast dat de sociale rechtvaardigheid in Vlaanderen en Brussel steeds meer afbrokkelt.

The world is at risk of descending into a climate “doom loop”, a thinktank report has warned. It said simply coping with the escalating impacts of the climate crisis could draw resources and focus away from the efforts to slash carbon emissions, making the situation even worse.

Examination of trees alive at the time shows three years of severe drought that may have caused crop failures and famine

Many people believe that wind, solar and electric vehicles are solutions to our energy problems. In this post I talk about the important role complexity plays. Growing complexity uses energy in hidden ways. The result tends to be more energy use, rather than less, as complex solutions such as wind turbines, solar panels and electric vehicles are added. Many measures of energy desirability give unreasonably favorable ratings to wind and solar and electric vehicles. The problem is that dual systems are needed, driving up energy consumption. Without enough energy, economies tend to collapse. This is a form of simplification.

The deployment of low-tech requires taking into account the human factor and changing design practices.

Electric utilities are likely responsible for the nation’s higher than expected emissions of sulfur hexafluoride, a greenhouse gas 25,000 times worse for the climate than carbon dioxide.

The climate crisis has begun to disrupt human societies by severely affecting the very foundations of human livelihood and social organisation. Climate impacts are not equally distributed across the world: on average, low- and middle-income countries suffer greater impacts than their richer counterparts. At the same time, the climate crisis is also marked by significant inequalities within countries. Recent research reveals a high concentration of global greenhouse gas emissions among a relatively small fraction of the population, living in emerging and rich countries. In addition, vulnerability to numerous climate impacts is strongly linked to income and wealth, not just between countries but also within them.

Le réchauffement climatique modifie profondément le cycle de l’eau à l’échelle mondiale. Pluies et humidité sont en train de changer partout dans le monde, de différentes manières. Un récent rapport fait le point sur les changements observés dans le cycle de l’eau dans le monde en 2022.

People in developing countries are feeling increasingly angry and “victimised” by the climate crisis, the US climate envoy John Kerry has warned, and rich countries must respond urgently. “I’ve been chronicling the increased frustration and anger of island states and vulnerable countries and small African nations and others around the world that feel victimised by the fact that they are a minuscule component of emissions,” he said. “And yet [they are] paying a very high price. Seventeen of the 20 most affected countries in the world, by the climate crisis, are in Africa, and yet 48 sub-Saharan countries total 0.55% of all emissions.”

It’s not just indifference. It’s an active, and deadly, cavalier attitude towards the lives of others: an example other nations follow

In 1998, as nations around the world agreed to cut carbon emissions through the Kyoto Protocol, America’s fossil fuel companies plotted their response, including an aggressive strategy to inject doubt into the public debate.

Mapped: Carbon Dioxide Emissions Around the World According to Our World in Data, the global population emits about 34 billion tonnes of carbon dioxide (CO₂) each year. Where does all this CO₂ come from? This graphic by Adam Symington maps out carbon emissions around the world, using 2018 data from the European Commission that tracks tonnes of CO₂ per 0.1 degree grid (roughly 11 square kilometers). This type of visualization allows us to clearly see not just population centers, but flight paths, shipping lanes, and high production areas. Let’s take a closer look at some of these concentrated (and brightly lit) regions on the map.

Shane White from www.worldenergydata.org has put together three very useful charts breaking down coal, oil and gas extraction by nation. 

In Europe, a large-scale war could cause the Baltic Sea to freeze over and severely compromise food security – potentially for decades and even centuries to come. An ever-growing body of work has shown that even a local nuclear conflict could usher in a climate catastrophe. As marine scientists, we have considered what this could specifically mean for the world’s oceans. In 1982, a group of scientists including Carl Sagan began to raise the alarm on a climate apocalypse that could follow nuclear war. Using simple computer simulations and historic volcanic eruptions as natural analogues, they showed how smoke that lofted into the stratosphere from urban firestorms could block out the sun for years.

The global economy urgently needs to bend its emissions curve downwards

National climate pledges would collectively require 1.2 billion hectares (about 3 billion acres) of land, researchers have found in a new study, The Land Gap Report. More than half of this land is already currently used for something else. This demand for land will put pressure on ecosystems, Indigenous lands, small farmers and food security. Protecting existing forests and securing Indigenous and community land rights are more effective than carbon capture plans requiring land-use change, including reforestation.

The State of Climate Action 2022 report analyzed progress across 40 indicators of action needed by 2030 and 2050 to limit warming to 1.5 degrees C, everything from increasing renewable energy uptake to halting deforestation to shifting to more sustainable diets. We found that none of the 40 indicators assessed are on track to achieve 2030 targets.

Semafor launched last week with the goal of “reinventing the news story.” The news story needs reinventing, they say, because people can no longer tell the difference between unbiased fact and opinion. According to the Observer, Semafor has already raised more than $25 million, the majority of which is coming from eight corporate sponsors who want to help the news outlet address distrust in media. One of those sponsors appears to be Chevron, the second biggest climate-polluting company in the world.

Governments and businesses failing to change fast enough, says United in Science report, as weather gets increasingly extreme. Despite intensifying warnings in recent years, governments and businesses have not been changing fast enough, according to the United in Science report published on Tuesday. The consequences are already being seen in increasingly extreme weather around the world, and we are in danger of provoking “tipping points” in the climate system that will mean more rapid and in some cases irreversible shifts.

Report and executive summary

The Earth is approximately 1.1℃ warmer than it was at the start of the industrial revolution. That warming has not been uniform, with some regions warming at a far greater pace. One such region is the Arctic. A new study shows that the Arctic has warmed nearly four times faster than the rest of the world over the past 43 years. This means the Arctic is on average around 3℃ warmer than it was in 1980.

School and university students all over the world are planning to take school strikes one step further and occupy our campuses to demand the end of the fossil economy. Taking a lesson from student activists in the 1960s, the climate justice movement’s youth will shut down business as usual. Not because we don’t like learning, but because what we’ve learned already makes it clear that, without a dramatic break from this system, we cannot ensure a livable planet for our presents and futures.

Wildfires, floods and soaring temperatures have made climate change real to many Americans. Yet a sizeable number continue to dismiss the scientific consensus that human activity is to blame. “Victory,” according to the American Petroleum Institute’s memo, “will be achieved when average citizens ‘understand’ (recognize) uncertainties in climate science… Unless ‘climate change’ becomes a non-issue… there may be no moment when we can declare victory.”

Civil unrest, political instability, food insecurity, mass migration and worsening human rights are the baked-in secondary impacts of climate change, but you wouldn’t know that from the undercooked approach of governments and business. As the extreme weather events the world is already experiencing become more frequent, they will trigger a cascade of these second-order climate risks across a huge swathe of countries.

World Population Prospects 2022 is the twenty-seventh edition of the official United Nations population estimates and projections. It presents population estimates from 1950 to the present for 237 countries or areas, underpinned by analyses of historical demographic trends. This latest assessment considers the results of 1,758 national population censuses conducted between 1950 and 2022, as well as information from vital registration systems and from 2,890 nationally representative sample surveys. The 2022 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and national levels. For the first time, the estimates and projections are presented in one-year intervals of age and time instead of the five-year intervals used previously.

Degrowth is a radical economic theory born in the 1970s. It broadly means shrinking rather than growing economies, to use less of the world’s dwindling resources. Detractors of degrowth say economic growth has given the world everything from cancer treatments to indoor plumbing. Supporters argue that degrowth doesn’t mean “living in caves with candles” – but just living a bit more simply.

The publication also provides most recent finding on climate related risks and impacts including on food security, humanitarian and population displacement aspects and impact on ecosystems.

Depuis le début du mois de mars, l’Inde et le Pakistan étouffent sous une vague de chaleur prolongée inédite. Selon une étude (en anglais) conduite par le World Weather Attribution, le changement climatique l’aurait rendu trente fois plus probable. Pour quantifier l’effet de celui-ci, une équipe internationale de vingt-neuf chercheurs a analysé des données météorologiques et des simulations informatiques, afin de comparer le climat tel qu’il est aujourd’hui — soit 1,2 °C plus chaud qu’à la fin des années 1800, avec le climat antérieur à cette période.

Et si une vie trop urbaine nous éloignait des enjeux environnementaux ?

Food supply expert paints grim global picture hunger 05.23.2022 By Arvin Donley NEW YORK, NEW YORK, US — Global wheat inventories currently stand at about 10 weeks of global consumption, a food supply expert said during a special meeting of the United Nations Security Council on May 19. Sara Menker, chief executive officer of Gro Intelligence, an organization that gathers and analyzes global food and agricultural data, said she disputes official government agency estimates that put global wheat inventories at 33% of annual consumption, countering inventories are closer to 20%. “It is important to note that the lowest grain inventory levels the world has ever seen are now occurring while access to fertilizers is highly constrained, and drought in wheat growing regions around the world is the most extreme it’s been in over 20 years,” Menker said. “Similar inventory concerns also apply to corn and other grains. Government estimates are not adding up.” Menker told the security council that while much of the blame

The IPBES #PandemicsReport is one of the most scientifically robust examinations of the evidence and knowledge about links between pandemic risk and nature since the COVID-19 pandemic began - with 22 of the world's leading experts from fields as diverse as epidemiology, zoology, public health, disease ecology, comparative pathology, veterinary medicine, pharmacology, wildlife health, mathematical modelling, economics, law, and public policy as authors of the report. The expertise of the 22 authors was further augmented by contributions and knowledge resources from the Convention on Biological Diversity, the Intergovernmental Panel on Climate Change, the Convention on International Trade in Endangered Species, the United Nations Convention to Combat Desertification, and the World Health Organization - as well as a peer review process.

The Bank of England governor warned last week of ‘apocalyptic’ food price rises. Yet war in Ukraine, climate change and inflation are already taking their toll all over the world. Apocalypse is an alarming idea, commonly taken to denote catastrophic destruction foreshadowing the end of the world. But in the original Greek, apokálypsis means a revelation or an uncovering. One vernacular definition is “to take the lid off something”.

Temperature exceeded 45°C (113°F) in late April in at least nine Indian cities,[1] on its way to 50°C (122°F) in Pakistan in May,[2] where a laborer says “It’s like fire burning all around” and a meteorologist describing growing heatwaves since 2015 says “The intensity is increasing, and the duration is increasing, and the frequency is increasing.” Halfway around the world, Canada and north-central United States were cooler than their long-term average, but people in British Columbia and northwest United States remember being under their own record-breaking hotspot last summer.

When people talk about ways to slow climate change, they often mention trees, and for good reason. Forests take up a large amount of the planet-warming carbon dioxide that people put into the atmosphere when they burn fossil fuels. But will trees keep up that pace as global temperatures rise? With companies increasingly investing in forests as offsets, saying it cancels out their continuing greenhouse gas emissions, that’s a multibillion-dollar question.

Oil and gas majors are planning scores of vast projects that threaten to shatter the 1.5C climate goal. If governments do not act, these firms will continue to cash in as the world burns

Planned drilling projects across US land and waters will release 140bn metric tons of planet-heating gases if fully realised, an analysis shared with the Guardian has found. The study, to be published in the Energy Policy journal this month, found emissions from these oil and gas “carbon bomb” projects were four times larger than all of the planet-heating gases expelled globally each year, placing the world on track for disastrous climate change.

There is a 50:50 chance of the annual average global temperature temporarily reaching 1.5 °C above the pre-industrial level for at least one of the next five years – and the likelihood is increasing with time, according to a new climate update issued by the World Meteorological Organization (WMO).

the new study has uncovered five other events around the world which were even more severe but were never reported. “The recent heatwave in Canada and the United States shocked the world. Yet we show there have been some even greater extremes in the last few decades. Using climate models, we also find extreme heat events are likely to increase in magnitude over the coming century – at the same rate as the local average temperature,”

A new study describes a period of rapid global climate change in an ice-capped world much like the present—but 304 million years ago. Within about 300,000 years, atmospheric carbon dioxide levels doubled, oceans became anoxic, and biodiversity dropped on land and at sea.

The world may be facing a devastating “hidden” collapse in insect species due to the twin threats of climate change and habitat loss.

Au début des années 1970, le club de Rome1 s’interroge sur la pérennité de la croissance dans un mode fini. Il confie une étude au Massachusetts Institute of Technology (MIT). Une équipe de recherche, emmenée par Dennis Meadows2, conçoit une modélisation du système socio-économique humain et de ses interactions avec la planète : le modèle World3. En 1972 paraît The Limits to Growth (Les limites à la croissance). Ce rapport, qui montre que la croissance a des limites, et que sa poursuite au-delà conduirait à l’effondrement du système, fait grand bruit.

Le "World Happiness Report" (WHR) crée par l’ONU mesure le bonheur à partir de six variables : revenu, liberté, confiance dans le gouvernement, espérance de vie en bonne santé, soutien social et générosité. Il dresse un classement de 150 pays dominé par la Finlande, le Danemark, l'Islande, la Suisse, les Pays-Bas puis la France en 20e position. Après deux ans de pandémie, l’indicateur est plus pertinent que jamais.

Rapid decarbonization of energy is non-negotiable if we are to avert catastrophic global heating, says the latest UN climate report.

A new analysis of flash droughts finds that droughts coming on suddenly seem to be striking faster in the last two decades, with approximately 33–46 percent of flash droughts now emerging within just five days.

New data suggests forests help keep the Earth at least half of a degree cooler, protecting us from the effects of climate crisis

Geen enkel land haalt de luchtkwaliteitsnormen van de Wereldgezondheidsorganisatie, en slechts in 3 procent van de steden blijft de luchtvervuiling binnen de perken. Dat is de conclusie van het jaarlijkse World Air Report van het IQAIr.

the IPCC’s latest report on climate change impacts, adaptation and vulnerability (we helped write the chapter on cities) made it explicit that people living in informal settlements in areas such as Bwaise are the most vulnerable urban populations to climate change.

The Ukrainian crisis has revived an old debate: how to effectively sanction a state like Russia? Let’s say it straight away: it is time to imagine a new type of sanction focused on the oligarchs who have prospered thanks to the regime in question. This will require the establishment of an international financial register, which will not be to the liking of western fortunes, whose interests are much more closely linked to those of the Russian and Chinese oligarchs than is sometimes claimed. However, it is at this price that western countries will succeed in winning the political and moral battle against the autocracies and in demonstrating to the world that the resounding speeches on democracy and justice are not simply empty words.

Researchers have been able to cut their carbon footprint by jetting off to fewer international conferences, but physicists working on large-scale experiments may also have to consider the significant environmental impact of the computer power they require. Michael Allen investigates

More than three-quarters of the world's largest rainforest has become less resilient to drought since the early 2000s, with areas near humans and with lower rainfall being the worst hit

February 28, 2022. Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.

At the beginning of nearly every war including the current one in Ukraine, there are those who loudly declare that it will be over shortly and then business-as-usual can resume. They are rarely right. While no one can say for certain what the trajectory of the Russian-Ukrainian conflict will be, the economic warfare that is going on alongside it is very likely to destroy the current global trading system.

BERLIN, Feb 28 – Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.

The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.

The frightful noise of gunfire, bombing and children’s screams in the cities of Ukraine reverberates across Europe. The full-scale Russian invasion launched last week is an unprovoked, heinous crime perpetrated against Ukraine’s citizens, their sovereign democratic state and all the free peoples of the world. The 24th of February is a day that will live in infamy. It will not be forgiven. It will surely never be forgotten.

On 28 February, the Intergovernmental Panel on Climate Change (IPCC), a United Nations body solely dedicated to looking at the science behind climate change, will release a major report on the impacts of the climate crisis and why it is imperative that we act now to address the growing risks. The report, which focuses on Impacts, Adaptation and Vulnerability, is expected to detail how climate impacts are already wreaking havoc in every part of the world and how, without much bolder action, more lives will be lost and more livelihoods destroyed. The report will look at challenges and solutions for addressing these risks and minimizing vulnerability unique to the world’s regions, cities and other habitats.

Why do we always make the same mistake? Oh, that’s only trouble in the Balkans, we say – and then an assassination in Sarajevo sparks the first world war. Oh, Adolf Hitler’s threat to Czechoslovakia is “a quarrel in a faraway country, between people of whom we know nothing” – and then we find ourselves in the second world war. Oh, Joseph Stalin’s takeover of distant Poland after 1945 is none of our business – and soon enough we have the cold war. Now we have done it again, not waking up until it is too late to the full implications of Vladimir Putin’s seizure of Crimea in 2014. And so, on Thursday 24 February 2022, we stand here again, clothed in nothing but the shreds of our lost illusions.

Only rarely does a book truly change the world. In the nineteenth century, such a book was Charles Darwin’s On the Origin of Species. For the twentieth century, it was The Limits to Growth. Not only did this best-selling 1972 publication help spur the environmental movement, but it showed that the underlying dynamics of the modern industrial world are unsustainable on the timescale of a couple of human lifetimes. This was profoundly important information, and it was delivered credibly and clearly, so that every policy maker could understand it.

There’s a new horse race in 2022. It’s one that we would rather lose than win. If our analysis is right, the world will probably blow through the 1.5°C global warming ceiling this decade; if we’re wrong, it could be delayed a decade. We argue[1],[2] that the apparent acceleration of global warming in the past decade is driven by an acceleration in the growth rate of human-made climate forcings, especially reduced human-made aerosol cooling – an effect that is not going away and may grow.

A violent bomb cyclone affecting Iceland on February 7 and 8, 2022, produced hurricane-force winds and record-breaking waves at the southern coast of the country. One of the waves reached 40 m (131 feet) and blew off the scale, making it by far the highest measured wave off the coast of Iceland and among the highest ever measured in the world.

Berlin est accusé d'ambiguïté dans la crise, entre l'impératif de solidarité avec les alliés occidentaux et Kiev, et la nécessité de ménager son grand fournisseur. Plus de 55% des importations allemandes de gaz viennent de Russie, un chiffre en hausse de 15 points depuis 2012, selon le dernier rapport "Statistic Review of World Energy".

Oil companies love to tell the world about the super cool technologies that have that will allow us to keep burning fossil fuels without cooking the climate. But those technologies are largely bullshit.

Experten wereldwijd zijn meer bezorgd over een gebrek aan klimaatactie, extreem weer en het verlies van biodiversiteit dan over de pandemie. Dat blijkt uit het laatste rapport van het World Economic Forum.

De coronapandemie mag dan wel het nieuws domineren, experten wereldwijd zijn meer bezorgd over een gebrek aan klimaatactie, over extreem weer en over het verlies van biodiversiteit. Dat blijkt uit het laatste rapport van het World Economic Forum, dat gisteren werd gepubliceerd.

En 2020, selon un rapport du World Resources Institute (WRI), ¼ de la population mondiale (environ 1,7 milliards de personnes) vit dans des pays en situation de stress hydrique (moins de 1700 m3 par an et par personne). Dans certaines régions du monde, les êtres humains disposent de moins de 3l d’eau par jour, alors que, selon l’OMS, la quantité adéquate d’eau potable représente au minimum 20 litres d’eau par habitant et par jour.

Un nouveau rapport du World Inequality Lab (WIR 2022) montre que les personnes les plus riches libèrent de plus grandes quantités de dioxyde de carbone que les personnes à moyens et faibles revenus

Le modèle économique des grandes entreprises est-il compatible avec la transition écologique ? Ne faudra-t-il pas un jour remettre en cause ce statu quo ? On s’interroge.

Selon les calculs du World Inequality Lab, le patrimoine est très inégalement réparti sur la planète. Exemple le plus extrême : les 1% des personnes les plus riches possèdent près de deux fois plus que les 90% des plus pauvres.

Satisfying the increased demand for food is placing pressure on the world’s water, land and soil resources. Agriculture has its part to play in alleviating these pressures and contributing positively to climate and development goals. Sustainable agricultural practices can lead to direct improvements in the state of land, soil and water, and generate ecosystem benefits as well as reduce emissions from land. Accomplishing all these requires accurate information and a major change in how we manage the resources. It also requires complementing efforts from outside the natural resources management domain to maximize synergies and manage trade-offs.

Le rapport 2022 sur les inégalités du World Inequality Lab, publié mardi, souligne que les ultra-riches ont énormément profité de la crise sanitaire du Covid-19, qui a creusé encore davantage les inégalités de patrimoine. Pour y remédier, les économistes ayant participé à l'étude, dont Lucas Chancel et Thomas Piketty, proposent une imposition progressive du patrimoine à l'échelle mondiale.

World leaders must commit to boosting cycling levels to reduce carbon emissions and reach global climate goals quickly and effectively

Morocco has become famous for its vast, world-leading solar arrays. But these mega-projects are just the start of the action on climate change that Morocco could be capable of delivering.

As 2100 looms closer, climate projections should look farther into the future, scientists say

While 32 countries generate atomic energy, nine have nuclear weapons and seven countries have both.

Temperature rises will top 2.4C by the end of this century, based on the short-term goals countries have set out, according to research published in Glasgow on Tuesday. That would far exceed the 2C upper limit the Paris accord said the world needed to stay “well below”, and the much safer 1.5C limit aimed for at the Cop26 talks.

Où dans le monde les gens émettent-ils le plus de CO2 ? (kilogramme par habitant et par an)

The annual "adaptation gap" report — which published Thursday amid the COP26 climate summit in Glasgow — found that the estimated costs to adapt to the worst effects of warming temperatures such as droughts, floods and rising seas in low-income countries are five to 10 times higher than how much money is currently flowing into those regions.

La déforestation est une des causes du réchauffement climatique, il est donc crucial de la limiter puisque les forêts permettent d’absorber 30% des émissions de dioxyde de carbone, un gaz à effet de serre, selon le World Resources Institute (WRI).

As a leading climate scientist, Paola Arias doesn’t need to look far to see the world changing. Shifting rain patterns threaten water supplies in her home city of Medellín, Colombia, while rising sea levels endanger the country’s coastline. She isn’t confident that international leaders will slow global warming or that her own government can handle the expected fallout, such as mass migrations and civil unrest over rising inequality. With such an uncertain future, she thought hard several years ago about whether to have children.

Here you can find out how many more climate extremes you will face across your lifetime relative to a world without climate change. The results are based on solid science.

At the global level, tropical areas are losing forests at a rate of 10 million hectares per year according to the FAO’s latest report on forest resources, and temperate areas, which are gaining forest area at a rate of 5 million hectares per year. Of the 10 million hectares of forest lost each year, just under two-thirds can be unambiguously attributed to agricultural expansion, with the remaining third being a combination of forest fires, logging and other factors.

Publiée ce mercredi par le World Inequality Lab (WIL), une étude a conclu que les individus les plus aisés polluent bien davantage que les plus pauvres sur la planète. A quelques jours de la COP26, les chercheurs estiment que les populations les plus riches devraient faire l’objet de mesures d’imposition ciblées.

Investeringen in duurzame energie leveren meer banen op dan geld pompen in fossiele brandstoffen. Ze zijn daarom beter geschikt om economieën uit het slop te trekken na de coronacrisis. Dat blijkt uit een rapport van het World Resources Institute, dat deze week verscheen.

“Putting biodiversity on a path to recovery is a defining challenge of this decade.” So begins the Kunming Declaration on biodiversity, adopted at the 15th UN biodiversity conference on October 13 2021, otherwise known as COP15.

Le système énergétique de demain sera « plus électrifié, plus efficace, plus interconnecté et plus propre », assure sans surprise l’Agence internationale de l’énergie (AIE) en préambule de son World Energy Outlook 2021(1) publié ce 13 octobre. Elle y déplore toutefois la lenteur de cette « transformation » ainsi que l'important rebond de la consommation mondial de charbon et de pétrole en 2021.

Rooftop solar panels are up to 79% cheaper than they were in 2010. These plummeting costs have made rooftop solar photovoltaics even more attractive to households and businesses who want to reduce their reliance on electricity grids while reducing their carbon footprints. But are there enough rooftop surfaces for this technology to generate affordable, low-carbon energy for everyone who needs it?

The UK is one of the world's most nature-depleted countries - in the bottom 10% globally and last among the G7 group of nations, new data shows. It has an average of about half its biodiversity left, far below the global average of 75%, a study has found.

With global warming intensifying the water cycle, floods and droughts are increasing, and many countries are unprepared.

An open letter sent on behalf of 1.8 million Fairtrade producers worldwide, ahead of COP26, urges world leaders to keep their promise to provide $100 billion in annual finance to low-income nations disproportionately hit by the climate crisis.

The most important climate talk at the highest political level—since the Paris climate conference in 2015—is set to take place in Glasgow, Scotland this year, from October 31 to November 12. This is the 26th Conference of Parties (COP26) of the United Nations Framework Convention on Climate Change (UNFCCC). This is not only the largest global climate summit, but also the largest global event as the sheer existence of the world will depend on the outcome of this year's conference.

The Status of Coral Reefs of the World: 2020 (L'état des récifs coralliens dans le monde : 2020) est un rapport du Réseau mondial de surveillance continue des récifs coralliens (GCRMN), un réseau de l'Initiative internationale pour les récifs coralliens (ICRI). Ses conclusions montrent qu'entre 2009 et 2018, une perte progressive d'environ 14 % des coraux dans les récifs coralliens du monde a été enregistrée, principalement causée par des épisodes de blanchiment récurrents à grande échelle. Au total, environ 11 700 kilomètres carrés de coraux durs ont été perdus, ce qui représente plus de la totalité des coraux vivant actuellement dans les récifs coralliens de l'Australie.

The world is dangerously off track to meet the Paris Agreement goals. The risks are compounding. Without immediate action the impacts will be devastating in the coming decades.

Table des émissions cumulatives de CO2 par pays et années

Une équipe de chercheurs de l'université de Lancaster, au Royaume-Uni, et de Small World Consulting Ltd, une société de conseil en développement durable, a estimé que l'informatique mondiale - comportant les téléphones, ordinateurs, télévisions et autres centres de données - génère entre 2,1 et 3,9 % des émissions mondiales de gaz à effet de serre (GES), contre 2,5 % pour l'aviation civile. Les chercheurs estiment qu'au regard de la façon dont le monde est de plus en plus connecté, ces émissions continueront d'augmenter de manière significative si aucune mesure n'est prise.

The research found 90% of coal and 60% of oil and gas reserves could not be extracted if there was to be even a 50% chance of keeping global heating below 1.5C, the temperature beyond which the worst climate impacts hit.

President Biden's climate envoy John Kerry says that unless the world’s top 20 worst emitters do not take “bold action” to tackle the climate crisis, the global environment will reach a point of no return.

The study from the UN University, the academic and research arm of the UN, looks at 10 different disasters that occurred in 2020 and 2021, and finds that, even though they occurred in very different locations and do not initially appear to have much in common, they are, in fact, interconnected.

The climate emergency is exploding in various parts of the world this week, but climate silence inexcusably continues to rein in much of the United States media.

All available evidence taken together, including physical understanding, observations over a larger region and different regional climate models give high confidence that human-induced climate change has increased the likelihood and intensity of such an event to occur and these changes will continue in a rapidly warming climate

Our rising power finally reached the point where we could destroy ourselves – the first point at which the risks to humanity from within exceeded the risks from the natural world. These extreme risks – high-impact threats with global reach – define our time. They range from global tragedies such as Covid-19, to existential risks which could lead to human extinction. By our estimates – weighing the different probabilities of events ranging from asteroid impact to nuclear war – the likelihood of the world experiencing an existential catastrophe over the next 100 years is one in six. Russian roulette.

As the world battles historic droughts, landscape-altering wildfires and deadly floods, a landmark report from global scientists says the window is rapidly closing to cut our reliance on fossil fuels and avoid catastrophic changes that would transform life as we know it. The state-of-the-science report from the United Nations' Intergovernmental Panel on Climate Change says the world has rapidly warmed 1.1 degrees Celsius higher than pre-industrial levels, and is now careening toward 1.5 degrees — a critical threshold that world leaders agreed warming should remain below to avoid worsening impacts.

The Atlantic Ocean's current system, an engine of the Northern Hemsiphere's climate, could be weakening to such an extent that it could soon bring big changes to the world's weather, a scientific study said on Thursday.

A Pandora’s box of environmental disasters has been opened, threatening the ability of the natural world to recover and humanity to survive. From devastating fires and storms to the emergence of deadly new viruses, it’s hard to deny the terrifying reality of climate change.

Around 13,000 researchers have called for urgent action to slow down the climate emergency as extreme weather patterns shock the world. They listed three core measures.

There are some phrases that should stop you in your tracks. The warning of a future that holds "untold suffering" is one of them. That is exactly what scientists from around the world are cautioning will happen if we don't take the threat of climate change seriously. In a paper published Wednesday in the journal BioScience, more than 14,000 scientists from 153 countries signed their name to research that warns of an incoming climate emergency.

Something powerful is happening around the world. The issue of climate change has moved from the margins to the mainstream, says Alok Sharma, the President-Designate of COP26, the United Nations climate conference set to take place in November 2021 in Glasgow, Scotland.

Herrington, a Dutch sustainability researcher and adviser to the Club of Rome, has made headlines in recent days after she authored a report that appeared to show a controversial 1970s study predicting the collapse of civilization was – apparently – right on time. Coming amid a cascade of alarming environmental events, Herrington’s work predicted the collapse could come around 2040 if current trends held.

Insects have declined by 75% in the past 50 years – and the consequences may soon be catastrophic. Biologist Dave Goulson reveals the vital services they perform

Around the world, activists are pushing to protect their rivers by giving them legal personhood. Is this just symbolism, or can it drive lasting environmental change?

The huge amount of money poured into the recovery from the pandemic—around $16 trillion, by the latest count—could have helped launch the world on a path to cut emissions quickly enough to meet the goals of the Paris climate agreement. But only around 2% of the spending is going to clean energy so far,

The Global Alliance for a Green New Deal is inviting politicians from legislatures in all countries to work together on policies that would deliver a just transition to a green economy ahead of Cop26 UN climate talks in Glasgow this November.

Rapid filling of a giant dam at the headwaters of the Nile River—the world's biggest waterway that supports millions of people—could reduce water supplies to downstream Egypt by more than one-third, new USC research shows.

Whenever an extreme weather or climate-related event occurs, the media and decision-makers ask the question to what extent it is influenced by climate change. For a few years now the scientific community has been able to answer that question for relatively simple extremes: hot and cold extremes, extreme precipitation and drought. This emerging field of climate science is called Extreme Event Attribution ...

Les scientifiques du World Weather Attribution, une initiative regroupant des experts de divers instituts de recherche dans le monde, ont estimé que le changement climatique avait rendu cet événement au minimum 150 fois plus susceptible de se produire.

be a source of information with regular updates on climate change lawsuits around the world. From cases grounded in human rights claims to straightforward tort suits, litigation relating to the climate crisis has grown substantially in recent years. And as the crisis continues and worsens, climate litigation is likely to rise as people increasingly seek relief through the courts.

During the last days of June 2021, Pacific northwest areas of the U.S. and Canada experienced temperatures never previously observed, with records broken in many places by several degrees Celsius.

A new report has found that by 2025, the world must remove 1 Gigatonne, or 1 billion tonnes, of carbon from the atmosphere to keep global warming within the Paris Agreement target of 1.5°C. However, projects in development will remove only a fraction of this. The report says, “Without action to deliver 1 Gigatonne (Gt) of negative emissions globally by 2025, keeping global warming within the Paris Agreement target of 1.5°C cannot be achieved.”

A landmark report by the world’s most senior climate and biodiversity scientists argues that the world will have to tackle the climate crisis and the species extinction crisis simultaneously, or not at all.

Legal experts from across the globe have drawn up a “historic” definition of ecocide, intended to be adopted by the international criminal court to prosecute the most egregious offences against the environment. The draft law, defines ecocide as “unlawful or wanton acts committed with knowledge that there is a substantial likelihood of severe and widespread or long-term damage to the environment being caused by those acts”.

More than half the world’s rivers stop flowing for at least one day per year, according to the first detailed global map of river flow. More rivers than that are expected to run dry if climate change and water management issues aren’t addressed.

A quel point le changement climatique est-il responsable des ravages agricoles causés par le gel tardif cette année ? C’est ce que le réseau international de scientifiques World Weather Attribution vient d’élucider. Et ce un mois après la vague de froid qui a entamé les perspectives de récoltes pour nombre d’agriculteurs.

In our latest study, scientists from France, Germany, Netherlands, and the UK collaborated to examine whether and to what extent human-induced climate change had a part to play in the cold early April following a very warm March 2021 that led to large scale frost damages in grapevines and fruit trees in central France.

The root cause of pandemics – the destruction of nature – is being ignored, scientists have warned. The focus of world leaders on responding to future outbreaks overlooks the far cheaper and more effective strategy of stopping the spillover of disease from animals to humans in the first place, they have said. The razing of forests and hunting of wildlife is increasingly bringing animals and the microbes they harbour into contact with people and livestock. About 70% of new infectious diseases have come from animals, including Covid-19, Sars, bird flu, Ebola and HIV.

Soils provide 95% of all food but are damaged by industrial, farming, mining and urban pollution. Soils are also the largest active store of carbon, after the oceans, and therefore crucial in fighting the climate crisis. But the report said industrial pollution, mining, farming and poor waste management are poisoning soils, with the “polluter pays” principle absent in many countries.

The world’s coal producers are currently planning as many as 432 new mine projects with 2.28 billion tonnes of annual output capacity, research published on Thursday showed, putting targets for slowing global climate change at risk. China, Australia, India and Russia account for more than three quarters of the new projects,

The world must rewild and restore an area the size of China to meet commitments on nature and the climate, says the UN, and the revival of ecosystems must be met with all the ambition of the space race. Existing conservation efforts are insufficient to prevent widespread biodiversity loss and ecosystem collapse, the global body has warned at the launch of the decade on ecosystem restoration, an urgent call for the large-scale revival of nature in farmlands, forests and other ecosystems.

The climate crisis is causing a widespread fall in oxygen levels in lakes across the world, suffocating wildlife and threatening drinking water supplies. Falling levels of oxygen in oceans had already been identified, but new research shows that the decline in lakes has been between three and nine times faster in the past 40 years. Scientists found oxygen levels had fallen by 19% in deep waters and 5% at the surface.

There is about a 40% chance of the annual average global temperature temporarily reaching 1.5°C above the pre-industrial level in at least one of the next five years – and these odds are increasing with time, according to a new climate update issued by the World Meteorological Organization (WMO). There is a 90% likelihood of at least one year between 2021-2025 becoming the warmest on record, which would dislodge 2016 from the top ranking, according to the Global Annual to Decadal Climate Update, produced by the United Kingdom’s Met Office, the WMO lead centre for such predictions.

A surge in food prices is deepening the pain caused by Covid-19 across the developing world, forcing millions into hunger and contributing to social problems that could lead to more political unrest and migration.

Governments must close gap between net zero rhetoric and reality, says International Energy Agency head

Agricultural pesticide use and its associated environmental harms is widespread throughout much of the world. Efforts to mitigate this harm have largely been focused on reducing pesticide contamination of the water and air, as runoff and pesticide drift are the most significant sources of offsite pesticide movement. Yet pesticide contamination of the soil can also result in environmental harm.

Sea ice land. 7 Tipping points are analysed here. Climate tipping points, elements of the Earth system in which small changes in global temperature can kick off reinforcing loops that ‘tip’ a system into a profoundly different state, accelerating heat waves, permafrost thaw, and coastal flooding — and, in some cases, fueling more warming.

Mapped: How climate change affects extreme weather around the world

Since the turn of the millennium, the world has been losing around 5 million hectares of forest every year. Nearly all of this occurs in the tropics; almost half of all deforestation takes place in Brazil and Indonesia. Three-quarters is driven by agriculture. Beef production is responsible for 41% of deforestation; palm oil and soybeans account for another 18%; and logging for paper and wood across the tropics, another 13%. These industries are also dominant in a few key countries.

Energy watchdog’s Fatih Birol says shift away from coal in key regions needs to be made a global priority

Water shortages are now affecting more than 3 billion people around the world, as the amount of fresh water available for each person has plunged by a fifth over two decades, data has shown. About 1.5 billion people are suffering severe water scarcity or even drought, as a combination of climate breakdown, rising demand and poor management has made agriculture increasingly difficult across swathes of the globe.

Comment regarder en face les limites planétaires ? Renoncer à nos activités non durables et polluantes ? Gérer l’héritage transmis aux générations futures (usines, routes, constructions…) ? Ces questions figurent au coeur de Closing Worlds, une initiative originale et prospective qui nous emmène sur les voies du renoncement.

Flying is a highly controversial topic in climate debates. It accounts for around 2.5% of global CO₂ emissions, but 3.5% when we take non-CO₂ impacts on climate into account.

Under a “climate lockdown,” governments would limit private-vehicle use, ban consumption of red meat, and impose extreme energy-saving measures, while fossil-fuel companies would have to stop drilling. To avoid such a scenario, we must overhaul our economic structures and do capitalism differently. Many think of the climate crisis as distinct from the health and economic crises caused by the pandemic. But the three crises – and their solutions – are interconnected.

Initiated in 2012, the World Forum for Democracy is a platform for dialogue and innovation in democratic governance, which promotes the Council of Europe principles across the world. It is a unique democratic experience.

L'étude annuelle, « BP Statistical Review of World Energy 2020 », est parue au mois de juin dernier. Pour la 69ème année consécutive, l'équipe d'économistes et de statisticiens de BP, a recueilli, vérifié et analysé les statistiques de l'énergie, en provenance du monde entier. Cette étude fournit aux chercheurs, aux entreprises, aux médias et aux politiques, une base de données mondiale exhaustive, sans équivalent.

For decades fossil fuel majors tried to fight the consensus – just as big tobacco once disputed that smoking kills.

Action on climate change is arguably the greatest challenge for public policy of our times. But despite economic forces being the major driver of the carbon dioxide problem, this column argues that economists have so far been too silent on the subject. For example, the Quarterly Journal of Economics, the most-cited journal in economics, has never published an article on climate change. Good economics can and should play a fundamental role in guiding the policy framework that will influence investment decisions in the coming years, so it is important that the profession dramatically increases its work now.

Advocates of the Green New Deal say there is great urgency in dealing with the climate crisis and highlight the scale and scope of what is required to combat it. We can afford it, with the right fiscal policies and collective will. But more importantly, we must afford it. The climate emergency is our third world war. Our lives and civilization as we know it are at stake, just as they were in the second world war.

Nonviolent protests are twice as likely to succeed as armed conflicts – and those engaging a threshold of 3.5% of the population have never failed to bring about change.

Humans will cause so many mammal species to go extinct in the next 50 years that the planet's evolutionary diversity won't recover for 3 to 5 million years, a team of researchers has found.

So it makes sense that, of all the patents found by the researchers, 47% belonged to Baden Aniline and Soda Factory (BASF), the largest chemical-producing company in the world. Collectively, Germany-based BASF owns 5,701 patents on sea life genes—more than any of the other 220 gene-patenting companies combined. Other major players include Dow Dupont, Bayer, Monsanto, Syngenta

For the first time, the world's tourism footprint has been quantified across the supply chain—from flights to souvenirs—and revealed as a significant and growing contributor to greenhouse gas (GHG) emissions.

If you read or listen to almost any article about climate change, it’s likely the story refers in some way to the “2 degrees Celsius limit.” The story often mentions greatly increased risks if the climate exceeds 2°C and even “catastrophic” impacts to our world if we warm more than the target.

In the early 1970s, ecologist Barry Commoner wrote The Closing Circle, in which he discussed the rapid growth of industry and technology and their persistent effect on all forms of life. He suggested that we can reduce the negative effects by sensitizing, informing and educating ourselves about our connection to the natural world. Commoner summarized the basics of ecology into what he termed “laws of ecology.” Others have also used this idea to develop simple statements that help us understand and remember our connections to nature. Here are five laws of ecology:

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. The findings of this study provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies. Rivers provide a m

Generating three centimeters of top soil takes 1,000 years, and if current rates of degradation continue all of the world's top soil could be gone within 60 years, a senior UN official said

From the Heart of the World - The Elder Brothers Warning is a documentary about the Kogi people who inhabit the Sierra Nevada de Santa Marta mountain in northern Colombia. Direct descendants of the Tayrona people they survived Spanish Conquistadors - a feat no other tribe can claim. Long thought extinct, they reappeared from their mountain home to warn the world about the harmful damage it was causing.
