Monthly global surface air temperature anomalies (°C) relative to 1850–1900 from January 1940 to June 2024, plotted as time series for all 12-month periods spanning July to June of the following year. The 12 months from July 2023 to June 2024 are shown with a thick red line, while all other 12-month periods are shown with thin lines shaded according to the decade, from blue (1940s) to brick red (2020s).

Simultaneous harvest failures across major crop-producing regions are a threat to global food security. Concurrent weather extremes driven by a strongly meandering jet stream could trigger such events, but so far this has not been quantified. Specifically, the ability of state-of-the art crop and climate models to adequately reproduce such high impact events is a crucial component for estimating risks to global food security. Here we find an increased likelihood of concurrent low yields during summers featuring meandering jets in observations and models. While climate models accurately simulate atmospheric patterns, associated surface weather anomalies and negative effects on crop responses are mostly underestimated in bias-adjusted simulations. Given the identified model biases, future assessments of regional and concurrent crop losses from meandering jet states remain highly uncertain. Our results suggest that model-blind spots for such high-impact but deeply-uncertain hazards have to be anticipated and acc

New research shows the company’s scientists were as “skillful” as independent experts in predicting how the burning of fossil fuels would warm the planet and bring about climate change.

Het affakkelen van gas in de fossiele brandstofindustrie klom vorig jaar naar het hoogste niveau sinds 2019, ondanks de groeiende internationale druk om de vervuilende praktijk aan banden te leggen.

Summary for Policymakers. A Report of the Intergovernmental Panel on Climate Change

Environ 500 personnes ont participé dimanche à une marche pour le climat à Bruxelles, a indiqué l’organisation à l’origine de l’évènement Rise For Climate Belgium. Par le biais de cet évènement intitulé "Touche pas à mon futur", l’organisation espère inciter la société civile à s’opposer à l’éventuelle réduction des politiques climatiques et aux politiques d’austérité, alors que l’extrême droite monte un peu partout en Europe.

Historical responsibility for climate change is radically shifted when colonial rule is taken into account, Carbon Brief analysis reveals.

Since the Paris Agreement in 2016, the world’s 60 largest private banks financed fossil fuels with USD $6.9 trillion. Nearly half – $3.3 trillion – went towards fossil fuel expansion. In 2023, banks financed $705 billion in fossil fuel financing with $347 billion going to fossil fuel expansion alone.

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

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.

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.

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.

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.

Le sommet européen Climate Chance Europe 2024 s'est déroulé les 8 et 9 février 2024 à Liège. Sur l'invitation de M. Philippe Henry, vice-président de la Wallonie et ministre du Climat, de l’Énergie, de la Mobilité et des Infrastructures, dans le cadre de la présidence belge du Conseil de l'Union européenne, j'ai eu l'honneur de donner un discours lors de la séance plénière d'ouverture. En voici la vidéo.

The new report evokes a mild sense of urgency, calling on governments to mobilise finance to accelerate the uptake of green technology. But its conclusions are far removed from a direct interpretation of the IPCC’s own carbon budgets (the total amount of CO₂ scientists estimate can be put into the atmosphere for a given temperature rise).

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.

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

As the public conversation on climate change evolves, so too does the sophistication and range of arguments used to downplay or discount the need for action (McKie, Reference McKie2019; Norgaard, Reference Norgaard2011). A mainstay of this counter-movement has been outright denial of the reality or human causation of climate change (Farrell et al., Reference Farrell, McConnell and Brulle2019), supplemented by climate-impact scepticism (Harvey et al., Reference Harvey, Van Den Berg, Ellers, Kampen, Crowther, Roessingh and Mann2018) and ad hominem attacks on scientists and the scientific consensus (Oreskes & Conway, Reference Oreskes and Conway2011). A fourth strategy has received relatively little attention to date: policy-focused discourses that exploit contemporary discussions on what action should be taken, how fast, who bears responsibility and where costs and benefits should be allocated (Bohr, Reference Bohr2016; Jacques & Knox, Reference Jacques and Knox2016; McKie, Reference McKie2019). We call these ‘

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.

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

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

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

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
