With current policies the Earth is on track to a warming of around 3 °C above preindustrial temperatures, a level of heat our planet has not seen for millions of years. Ecosystems, human society and infrastructure are not adapted to these temperatures. Due to non-linear effects, the impacts will be much more severe than just three times as bad as after 1 °C of warming. Land areas will continue to warm much more than the global average, many regions twice as much or even more. Extreme heat will become far more frequent and a major cause of human mortality, making large parts of the tropical land area essentially too hot to live. In addition, extreme rainfall and flooding, droughts, wildfires and harvest failures will increase in frequency and severity. The destructive power of tropical cyclones will also increase. Sea-level rise will accelerate further, and the destabilization of ice sheets will commit our descendants to loss of coastal cities and island nations. The risk of crossing devastating and irreversib

Annually updated, IPCC AR6 consistent indicators of human-induced global warming, greenhouse gas emissions, and the remaining global carbon budget.

Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC). Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We follow methods as close as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report. We compile monitoring datasets to produce estimates for key climate indicators related to forcing of the climate system: emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activit

If currently implemented policies are continued with no increase in ambition, there is a 90% chance that the Earth will warm between 2.3°C and 4.5°C, with a best estimate of 3.5°C.

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 Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN), is the first book to document the development and nature of climate obstruction activities across Europe, which are efforts to deliberately slow or block climate action. Climate obstruction strategies range from outright denial to more subtle forces of delay and the spread of disinformation

Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN) and published via Oxford University Press, reveals extensive networks impeding climate action within the region and surrounding states. In Italy and Germany, far-right networks spread misinformation by questioning climate science’s validity, while in Spain and the UK, blame-shifting and deflecting responsibility for climate action are common. European-based fossil fuel industries, like Shell, engage in greenwashing, by framing gas as a ‘bridging technology crucial for the energy transition’, delaying genuine progress.

Women and gender-diverse people bear the brunt of climate change’s negative affects. If Australia wants to be taken seriously on climate action, this needs addressing.

Insight and inspiration in turbulent times. People have widely varying beliefs about climate change. A surprising number still think that it’s a hoax, or that it’s a trivial problem. At the other end of the opinion spectrum, some say it signals the end of the world and there’s nothing we can do to stop it. Between those extremes are lots of folks who believe climate change is a serious dilemma, but we can deal with it by installing solar panels, nuclear power, solar radiation management technologies, and/or machines to remove carbon dioxide (CO2) from the atmosphere, after which we will continue to live mostly the way we do today.

Human-caused climate crisis brought soaring temperatures across Asia, from Gaza to Delhi to Manila

Record-breaking temperatures were recorded across the globe in 2023. Without climate action, adverse climate-related health impacts are expected to worsen worldwide, affecting billions of people. Temperatures in Europe are warming at twice the rate of the global average, threatening the health of populations across the continent and leading to unnecessary loss of life. The Lancet Countdown in Europe was established in 2021, to assess the health profile of climate change aiming to stimulate European social and political will to implement rapid health-responsive climate mitigation and adaptation actions. In 2022, the collaboration published its indicator report, tracking progress on health and climate change via 33 indicators and across five domains.

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

Here, we show that the Last Glacial Maximum (LGM) provides a stronger constraint on equilibrium climate sensitivity (ECS), the global warming from increasing greenhouse gases, after accounting for temperature patterns. Feedbacks governing ECS depend on spatial patterns of surface temperature (“pattern effects”); hence, using the LGM to constrain future warming requires quantifying how temperature patterns produce different feedbacks during LGM cooling versus modern-day warming. Combining data assimilation reconstructions with atmospheric models, we show that the climate is more sensitive to LGM forcing because ice sheets amplify extratropical cooling where feedbacks are destabilizing. Accounting for LGM pattern effects yields a median modern-day ECS of 2.4°C, 66% range 1.7° to 3.5°C (1.4° to 5.0°C, 5 to 95%), from LGM evidence alone. Combining the LGM with other lines of evidence, the best estimate becomes 2.9°C, 66% range 2.4° to 3.5°C (2.1° to 4.1°C, 5 to 95%), substantially narrowing uncertainty compared t

Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average tempe

Decarbonization efforts and sustainability transformations represent highly contested socio-political projects. Yet, they often encounter various forms of depoliticization. This article illuminates how a grand socio-ecological challenge like the energy transition gets depoliticized by an unusual suspect, namely Germany's Green Party. Based on a qualitative content analysis of Green Party programs, party conventions, and additional documents published between 1980 and 2021, this article traces how the Green Party has depoliticized the energy transition over time, emphasizing a shift from radical societal change to ecological modernization. The changing stance of the German Greens on the country's energy transition reflects more profound changes of a future society the party collectively envisions through their energy and climate change agenda. These changes result from a struggle between moderates advocating incremental political reforms and radicals aiming for more fundamental and systemic societal change.

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i

Mitigating climate change necessitates global cooperation, yet global data on individuals’ willingness to act remain scarce. In this study, we conducted a representative survey across 125 countries, interviewing nearly 130,000 individuals. Our findings reveal widespread support for climate action. Notably, 69% of the global population expresses a willingness to contribute 1% of their personal income, 86% endorse pro-climate social norms and 89% demand intensified political action. Countries facing heightened vulnerability to climate change show a particularly high willingness to contribute. Despite these encouraging statistics, we document that the world is in a state of pluralistic ignorance, wherein individuals around the globe systematically underestimate the willingness of their fellow citizens to act. This perception gap, combined with individuals showing conditionally cooperative behaviour, poses challenges to further climate action. Therefore, raising awareness about the broad global support for climat

Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim

Small modular reactors (SMRs) have been the subject of endless hype in recent years but in fact, no SMRs have ever been built, none are being built now and in all likelihood none will ever be built because of the prohibitive costs. SMRs are defined as reactors with a capacity of 300 megawatts (MW) or less with serial factory production of reactor components (or ‘modules’). No SMRs have been built, but dozens of small (<300 MW) power reactors have been built in numerous countries, without factory production of reactor components.

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.

Humanity faces ‘devastating domino effects’ including mass displacement and financial ruin as planet warms

Referring to the Paris Agreement’s target of keeping Earth from warming no more than 1.5 degrees Celsius since the Industrial Revolution, the number has become a rallying cry for climate advocates and scientists, who say the goal is humanity’s best bet on avoiding the most catastrophic outcomes of climate change by the end of the century. Venturing even 0.5 degrees past that threshold could drastically increase the frequency and severity of extreme weather, biodiversity loss, famine and water scarcity, as well as make it more likely that tipping points accelerate warming further, climate scientists say.

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.

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.”

Life on planet Earth is under siege. We are now in an uncharted territory. For several decades, scientists have consistently warned of a future marked by extreme climatic conditions because of escalating global temperatures caused by ongoing human activities that release harmful greenhouse gasses into the atmosphere. Unfortunately, time is up. We are seeing the manifestation of those predictions as an alarming and unprecedented succession of climate records are broken, causing profoundly distressing scenes of suffering to unfold. We are entering an unfamiliar domain regarding our climate crisis, a situation no one has ever witnessed firsthand in the history of humanity.

Ocean-driven melting of floating ice-shelves in the Amundsen Sea is currently the main process controlling Antarctica’s contribution to sea-level rise. Using a regional ocean model, we present a comprehensive suite of future projections of ice-shelf melting in the Amundsen Sea. We find that rapid ocean warming, at approximately triple the historical rate, is likely committed over the twenty-first century, with widespread increases in ice-shelf melting, including in regions crucial for ice-sheet stability. When internal climate variability is considered, there is no significant difference between mid-range emissions scenarios and the most ambitious targets of the Paris Agreement. These results suggest that mitigation of greenhouse gases now has limited power to prevent ocean warming that could lead to the collapse of the West Antarctic Ice Sheet. The authors use a regional ocean model to project ocean-driven ice-shelf melt in the Amundsen Sea. Already committed rapid ocean warming drives increased melt, regard

The oil and gas industry, which includes many of the most profitable and powerful businesses in the world, is directly and indirectly responsible for more than 40% of carbon emissions—impacting the lives of billions of people, many living in the world's most remote and low-resourced communities. A new study proposes aggressive energy policies that would enable immediate and substantive decreases to carbon emissions and recommends a heightened level of government, corporate and citizen action to accelerate the decarbonization of the global economy, aiming to minimize the number of projected human deaths.

As we mark 100 days until the COP28 UN climate summit, the urgency of addressing the climate crisis has never been more palpable. Global failures to mitigate emissions and adapt to the impacts continue to wreak havoc on the planet, and we’re seeing this in a range of ways. Unprecedented extreme weather events have occurred with frightening regularity in 2023. In March, over 500 people lost their lives when Cyclone Freddy struck Malawi. Last month, flooding in the Philippines caused by Typhoons Doksuri and Khanun displaced more than 300,000 people, and the recent wildfires that ravaged Hawaii – in part exacerbated by climate change – continue to make for distressing headlines. This list is likely to become even longer by the end of the year, when COP28 gets underway in the United Arab Emirates (UAE).

Heatwaves, wildfires and floods are just the ‘tip of the iceberg’, leading climate scientists say

More than 1 billion cows around the world will experience heat stress by the end of the century if carbon emissions are high and environmental protection is low, according to new research published in Environmental Research Letters. This would mean cattle farming would face potentially lethal heat stress in much of the world, including Central America, tropical South America, Equatorial Africa, and South and Southeast Asia.

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.

There has been a strong push to promote increased investments in new nuclear power as a strategy to decarbonize economies, especially in the European Union (EU) and the United States (US). The evidence base for these initiatives is poor. Investments in new nuclear power plants are bad for the climate due to high costs and long construction times. Given the urgency of climate change mitigation, which requires reducing emissions from the EU electricity grid to almost zero in the 2030s (Pietzcker et al.1), preference should be given to the cheapest technology that can be deployed fastest. On both costs and speed, renewable energy sources beat nuclear. Every euro invested in new nuclear plants thus delays decarbonization compared to investments in renewable power. In a decarbonizing world, delays increase CO2 emissions. Our thoughts focus on new nuclear power plants (not phasing out existing plants) in the US and Europe. In Europe, new nuclear power plants are planned or seriously discussed in France, Czechia, Hu

In a speech about climate change from April 4th of this year, UN General Secretary António Guterres lambasted “the empty pledges that put us on track to an unlivable world” and warned that “we are on a fast track to climate disaster” (1). Although stark, Guterres’ statements were not novel. Guterres has made similar remarks on previous occasions, as have other public figures, including Sir David Attenborough, who warned in 2018 that inaction on climate change could lead to “the collapse of our civilizations” (2). In their article, “World Scientists’ Warning of a Climate Emergency 2021”—which now has more than 14,700 signatories from 158 countries—William J. Ripple and colleagues state that climate change could “cause significant disruptions to ecosystems, society, and economies, potentially making large areas of Earth uninhabitable”

Europe at the forefront of the climate challenge The European Union is a global leader in the transition to a net-zero greenhouse gas emissions economy. Playing a crucial role in international political efforts to tackle the climate challenge, Europe is one of the main players moving with urgency toward the Paris Agreement objectives. Now, with a European Green Deal and a commitment to reduce CO2 emissions by 55% by 2030, Europe has a clear, tangible roadmap to deliver such ambition. A wave of mass mobilisation, from climate marches to school strikes, is pressuring politicians to go further and faster. As a free-market democracy and the world’s largest single market, Europe is a key laboratory for innovative business and progressive social reform. It promises to bring groundbreaking change to globalised industries, from shipping to finance to aviation. Europe also has the power to demonstrate to the world that tackling climate change can go hand in hand with economic growth, social justice and a better qualit

Climate change refers to long-term variation in Earth's climate effected by heating imbalances from natural (e.g., solar, volcanic, and internal dynamics) and human sources (e.g., greenhouse gas emissions and land use). Following the onset of the Industrial Revolution, and particularly since the 1960s, global climate has warmed primarily as a consequence of rising greenhouse-gas concentrations in the atmosphere related to industrial activity. This page provides a selection of template maps and timeseries depicting changes in temperature, precipitation, and other aspects of climate over the past century, and how they are projected to change in the future.

Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC), including the first global stocktake under the Paris Agreement that will conclude at COP28 in December 2023. Evidence-based decision-making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles. We follow methods as close as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report. We compile monitoring datasets to produce estimates for key climate indicators related to forcing of the climate system: emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radia

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

Improved knowledge of glacial-to-interglacial global temperature change implies that fastfeedback equilibrium climate sensitivity (ECS) is 1.2 ± 0.3°C (2σ) per W/m2 . Consistent analysis of temperature over the full Cenozoic era – including “slow” feedbacks by ice sheets and trace gases – supports this ECS and implies that CO2 was about 300 ppm in the Pliocene and 400 ppm at transition to a nearly ice-free planet, thus exposing unrealistic lethargy of ice sheet models. Equilibrium global warming including slow feedbacks for today’s human-made greenhouse gas (GHG) climate forcing (4.1 W/m2) is 10°C, reduced to 8°C by today’s aerosols. Decline of aerosol emissions since 2010 should increase the 1970-2010 global warming rate of 0.18°C per decade to a post-2010 rate of at least 0.27°C per decade. Under the current geopolitical approach to GHG emissions, global warming will likely pierce the 1.5°C ceiling in the 2020s and 2°C before 2050. Impacts on people and nature will accelerate as global warming pumps up hydr

Terrestrial ecosystems have taken up about 32% of the total anthropogenic CO2 emissions in the past six decades1. Large uncertainties in terrestrial carbon–climate feedbacks, however, make it difficult to predict how the land carbon sink will respond to future climate change2. Interannual variations in the atmospheric CO2 growth rate (CGR) are dominated by land–atmosphere carbon fluxes in the tropics, providing an opportunity to explore land carbon–climate interactions3–6. It is thought that variations in CGR are largely controlled by temperature7–10 but there is also evidence for a tight coupling between water availability and CGR11. Here, we use a record of global atmospheric CO2, terrestrial water storage and precipitation data to investigate changes in the interannual relationship between tropical land climate conditions and CGR under a changing climate. We find that the interannual relationship between tropical water availability and CGR became increasingly negative during 1989–2018 compared to 1960–1989

Flash drought, characterized by unusually rapid drying, can have substantial impact on many socioeconomic sectors, particularly agriculture. However, potential changes to flash drought risk in a warming climate remain unknown. In this study, projected changes in flash drought frequency and cropland risk from flash drought are quantified using global climate model simulations. We find that flash drought occurrence is expected to increase globally among all scenarios, with the sharpest increases seen in scenarios with higher radiative forcing and greater fossil fuel usage. Flash drought risk over cropland is expected to increase globally, with the largest increases projected across North America (change in annual risk from 32% in 2015 to 49% in 2100) and Europe (32% to 53%) in the most extreme emissions scenario. Following low-end and medium scenarios compared to high-end scenarios indicates a notable reduction in annual flash drought risk over cropland. Flash droughts are projected to become more frequent unde

This paper catalogues current efforts to address climate change within multilateral economic and financial institutions and related organizations. It also proposes a minimum set of policy measures that need to be prioritized by such institutions to support climate change mitigation and adaptation. The proposals include expanding public climate finance via multilateral development banks, doing more to mobilize private investment, mainstreaming climate considerations across institutional operations, making climate disclosures mandatory, and addressing sovereign debt distress to unlock private climate finance.

The damage functions in the models, which relate GDP to temperature and sea-level rise, account for impacts on agriculture, forestry, fisheries, floods, road infrastructure, energy supply and demand, and labor productivity. Using this novel approach, the researchers estimate that the avoided damages are 1.5-3.9 times higher than the costs of climate mitigation. In other words, one euro invested in climate solutions saves the world about 1.5 to 4 euros in effects from climate change.

Net-zero targets imply that continuing residual emissions will be balanced by carbon dioxide removal. However, residual emissions are typically not well defined, conceptually or quantitatively. We analysed governments’ long-term strategies submitted to the UNFCCC to explore projections of residual emissions, including amounts and sectors. We found substantial levels of residual emissions at net-zero greenhouse gas emissions, on average 18% of current emissions for Annex I countries. The majority of strategies were imprecise about which sectors residual emissions would originate from, and few offered specific projections of how residual emissions could be balanced by carbon removal. Our findings indicate the need for a consistent definition of residual emissions, as well as processes that standardize and compare expectations about residual emissions across countries. This is necessary for two reasons: to avoid projections of excessive residuals and correspondent unsustainable or unfeasible carbon-removal level

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.

The NASA climate spiral 1880-2022. This version is in Celsius; see below for an alternate version in Fahrenheit. Both a 30 fps, 60 second duration video and 60 fps, 30 second duration video are available. The visualization presents monthly global temperature anomalies between the years 1880-2022. Temperature anomalies are deviations from a long term global avergage. In this case the period 1951-1980 is used to define the baseline for the anomaly. These temperatures are based on the GISS Surface Temperature Analysis (GISTEMP v4), an estimate of global surface temperature change. The data file used to create this visualization is publically accessible here.The term 'climate spiral' describes an animated radial plot of global temperatures.

An alternate timeline that ends with a Nobel prize for Exxon’s CEO.

We are writing to urge you to push the United Arab Emirates to withdraw the appointment of Sultan Al Jaber, head of the Abu Dhabi National Oil Company, as President-designate of the United Nations Framework Convention on Climate Change Conference of Parties 28 (COP 28). The decision to name the chief executive of one of the world’s largest oil and gas companies as president of the next U.N. Climate Change Conference risks jeopardizing climate progress from successive U.N. Climate Conferences. To help ensure that COP 28 is a serious and productive climate summit, we believe the United States should urge the United Arab Emirates to name a different lead for COP 28 or, at a minimum, seek assurances that it will promote an ambitious COP 28 aligned with the 1.5 degrees Celsius limit and Intergovernmental Panel on Climate Change (IPCC) findings and take concrete steps to demonstrate domestic and regional leadership toward this end.

Three “super-tipping points” for climate action could trigger a cascade of decarbonisation across the global economy, according to a report. Relatively small policy interventions on electric cars, plant-based alternatives to meat and green fertilisers would lead to unstoppable growth in those sectors, the experts said. But the boost this would give to battery and hydrogen production would mean crucial knock-on benefits for other sectors including energy storage and aviation.

A comprehensive new study led by Professor Gwen Robbins Schug at UNC Greensboro traces the impact of rapid climate change events on humans over the past 5,000 years and offers lessons for today's policymakers. The meta-analysis of approximately a decade's worth of bioarchaeology data was published today as a Proceedings of the National Academy of Sciences perspective article by a team of 25 authors representing 21 universities.

Mexico announced this Tuesday a set of measures to ban solar geoengineering experiments in the country, after a US startup began releasing sulfur particles into the atmosphere in the northern state of Baja California.

Carbon credits and offsets do not have a great record but the funds they raise are a vital part in fight against deforestation

Carbon offsets can help achieve emissions goals, some experts argue, while others say they are actively dangerous

The oil giant Exxon privately “predicted global warming correctly and skilfully” only to then spend decades publicly rubbishing such science in order to protect its core business, new research has found.

Il y avait les Argonautes. Et désormais, il y aura les Climatonautes. Une vingtaine de volontaires qui ont choisi de suivre l’aventurier chercheur Christian Clot pour trois folles expéditions en milieux extrêmes, afin de permettre aux scientifiques d’étudier comme jamais la façon dont les humains s’adaptent aux changements climatiques. Stéphane Besnard, le responsable médical et le codirecteur scientifique des études des expéditions, nous dévoile aujourd’hui les dessous de ce projet nommé Deep Climate.

In the U.K., Extinction Rebellion is shifting to a more moderate strategy in 2023. It could mark a tone shift for the climate movement.

World Weather Attribution ties disasters and extreme conditions to climate change—providing crucial leverage for legal and policy battles.

Over the past 12 months, courts from Indonesia to Australia have made groundbreaking rulings that blocked polluting power plants and denounced the human rights violations of the climate crisis. But 2023 could be even more important, with hearings and judgments across the world poised to throw light on the worst perpetrators, give victims a voice and force recalcitrant governments and companies into

An international team of scientists painstakingly gathered data from more than 50 years of seagoing scientific drilling missions to conduct a first-of-its-kind study of organic carbon that falls to the bottom of the ocean and gets drawn deep inside the planet.

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.”

Overall, however, the climate crisis is bleaker than it has ever been. In October, a slew of reports laid bare how close the planet had neared to irreversible climate breakdown, with one UN study stating there was “no credible pathway in place to 1.5C”, the internationally agreed limit for global heating, and that progress on cutting carbon emissions was “woefully inadequate”.

The past year saw major developments in accountability cases against oil companies and national governments around the world, as well as setbacks for several high-profile fossil fuel projects.

Most expensive storm cost $100bn while deadliest floods killed 1,700 and displaced 7 million, report finds

The world’s reliance on hi-tech capitalist solutions to the climate and ecological crises is perpetuating racism, the outgoing UN racism rapporteur has warned. Green solutions including electric cars, renewable energy and the rewilding of vast tracts of land are being implemented at the expense of racially and ethnically marginalised groups and Indigenous peoples, Tendayi Achiume told the Guardian in an interview.

Climate Change Laws of the World is a global database of climate change laws, policies, climate targets and litigation cases

De internationale scheepvaart bleef lang buiten schot bij klimaatakkoorden. Maar nu groeit ook voor die sector de internationale steun, ook van verschillende opkomende economieën, voor strengere klimaatdoelen. Maar er blijven zorgen over de kosten.

The UN-backed ‘Carbon Removal Pioneers’ stoke the development dreams of African countries but crash against the reality of climate science.

More than half of young people think "humanity is doomed" due to climate change. We need to reframe the narrative from doom and sacrifice, to one of opportunity.

Improved knowledge of glacial-to-interglacial global temperature change implies that fast- feedback equilibrium climate sensitivity is at least ~4°C for doubled CO2 (2×CO2), with likely range 3.5-5.5°C. Greenhouse gas (GHG) climate forcing is 4.1 W/m2 larger in 2021 than in 1750, equivalent to 2×CO2 forcing. Global warming in the pipeline is greater than prior estimates. Eventual global warming due to today’s GHG forcing alone – after slow feedbacks operate – is about 10°C. Human-made aerosols are a major climate forcing, mainly via their effect on clouds. We infer from paleoclimate data that aerosol cooling offset GHG warming for several millennia as civilization developed. A hinge-point in global warming occurred in 1970 as increased GHG warming outpaced aerosol cooling, leading to global warming of 0.18°C per decade. Aerosol cooling is larger than estimated in the current IPCC report, but it has declined since 2010 because of aerosol reductions in China and shipping. Without unprecedented global actions to

The coasts of Alaska are piled up with dead birds dying of starvation. Experts say that climate change is resulting in shifts in the food chain.

Climate disorder won’t be remedied through an orderly march of green energy. The world must also rein in consumption.

More than two decades on from the protocol, country shows enthusiasm for nuclear restarts over renewables

Qui sont les plus gros émetteurs de CO2 dans le monde ? Et y en a-t-il près de chez vous ? Une carte, réalisée par Climate Trace, vous permet de visualiser très simplement ces informations.

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.

A climate protester who blocked a lane of traffic on Sydney Harbour Bridge has been sentenced to 15 months in prison with a non-parole period of eight months, with human rights advocates labelling the punishment “disproportionate”.

La coalition Climate Trace a dévoilé début novembre un nouvel outil permettant d'observer les emplacements exacts des sites les plus polluants. Une carte détaillée qui doit aider les pays et les entreprises à rechercher des moyens efficaces pour atteindre la décarbonisation. Cet outil indépendant, répertoriant les émissions de gaz à effet de serre à travers le monde, a été présenté par Al Gore, à l'occasion du sommet des Nations unies sur le climat (COP27) en Égypte.

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

Alors que les émissions carbone ne cessent d’augmenter, une initiative imaginée par la coalition Climate Trace vient apporter un nouvel éclairage sur les sites et les secteurs les plus polluants. Répertoriant des dizaines de milliers de données sur une seule et unique carte, ce nouvel outil accessible gratuitement a été salué lors de la COP27 en Égypte.

"KEEP 1.5 ALIVE" has been the mantra of recent global climate conferences. But more and more mainstream organisations now say our politicians have already failed, and that average global temperature increases higher than 1.5 degrees Celsius above pre-industrial levels are now inevitable. So, who are we to believe?

The Center for Climate and Security (CCS), a non-partisan institute of the Council on Strategic Risks, has a team and distinguished Advisory Board of security and military experts. CCS envisions a climate-resilient world which recognizes that climate change threats to security are already significant, unprecedented and potentially existential, and acts to address those threats in a manner that is commensurate to their scale, consequence and probability.

The Sea Port Oil Terminal, 30 miles off the Texas coast, is the first of four proposed offshore terminals designed to dramatically expand the U.S. oil export capacity.

Na de klimaattop in Egypte staat er volgende maand al opnieuw een belangrijke milieutop op de agenda. In het Canadese Montreal moet de internationale gemeenschap het eens worden over een historisch akkoord over natuur en biodiversiteit, dat zich kan meten met het Klimaatakkoord van Parijs.

We know that the easiest way for a politician to secure power is to appease those who already possess it, those whose power transcends elections: the oil barons, the media barons, the corporations and financial markets. We know that this power appoints the worst possible people at the worst possible time. We know how, as elderly billionaires seek to grab ever more of the life that slips from them, they create a death cult....

The climate talks are going into overtime with little progress toward the emissions cuts required to meet the goals of the Paris Agreement.

COP27-gastland Egypte gaat meer van de vervuilende zware stookolie mazout gebruiken in twintig elektriciteitscentrales om gas vrij te maken voor uitvoer naar Europa.

Op de VN-klimaattop in Egypte toont de Europese Unie zich dan toch bereid om te praten over een nieuw mechanisme voor klimaathulp aan ontwikkelingslanden. Maar dan moeten grote economieën als China mee betalen.

La guerre en Ukraine place l’Europe « à un tournant » de sa politique énergétique et climatique selon Climate Action Tracker : soit remplacer sa dépendance à la Russie par de nouvelles dépendances, soit « accélerer le développement des énergies renouvelables et de l’efficacité énergétique ». D’urgence et massivement.

The map shows the Climate Shift Index (CSI) for the daily average temperature. High CSI values mean climate change made the temperatures more likely.

Le Climate Shift Index, CSI, permet de voir si, à une datte donnée, une température est dans la norme ou influencée par le changement climatique.

In his Cop27 speech this week, our will-he-go, won’t-he-go prime minister said that stopping the planet dangerously overheating was still within our grasp, leaving many wondering just what planet he was on. According to Rishi Sunak, last year’s Cop26 climate conference in Glasgow was all about keeping alive the possibility of preventing the global average temperature rise since the Industrial Revolution from climbing above 1.5C. That is “alive”, as in connected to a drip, in a coma and suffering cardiac arrest every few hours.

All students at the University of Barcelona will have to take a mandatory course on the climate crisis after the establishment agreed to meet the demands of activists conducting a sit-in occupation. The announcement came after a seven-day occupation by a group from the anti-fossil fuel organisation End Fossil Barcelona.

Nu een van de belangrijkste verwezenlijkingen van de VN-klimaattop in Glasgow van vorig jaar - een breed gedragen verbintenis om ontbossing een halt toe te roepen - vertaald moet worden in concrete actie, haken de meeste ondertekenaars af. Rusland, Indonesië en Congo zijn maar enkele van de bosrijke landen die zich teruggetrokken hebben.

Read Prime Minister Alexander De Croo's full speech at the climate conference in Sharm El Sheikh here. In his speech, the Prime Minister made the case for inclusivity and cooperation to tackle the climate crisis. Young, old, private, public sector, north, south, we must all go all-in to tackle today's challenges

Rich countries must urgently develop a plan to assist countries suffering the ravages of extreme weather, as failure to take early action on the climate crisis has left them increasingly vulnerable, developing nations have said. The V20 – made up of the 20 vulnerable countries facing the worst impacts of the climate crisis, and least able to cope with them – set out its proposals on Monday for how rich countries should pay for the “loss and damage” caused by the climate crisis.
