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

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

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

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.

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.

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.

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.

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

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).
