Between 80% and 89% of the world’s people want their governments to do more about climate change. This fact is the central tenet of the 89% Project for climate journalism. Timed to coincide with Earth Day and Earth Week, the project launched in April, 2025, and will culminate in another week of focused stories in October, just before the next COP meeting in Brazil.

Major mapping project reveals PFAS have been found at high levels at thousands of sites across Europe. EURACTIV's media partner, The Guardian, reports. Pollutants known as “forever chemicals”, which don’t break down in the environment, build up in the body and may be toxic, have been found at high levels at thousands of sites across the UK and Europe, a major mapping project has revealed.

The March for Science (formerly known as the Scientists' March on Washington)[6] was an international series of rallies and marches held on Earth Day. The inaugural march was held on April 22, 2017, in Washington, D.C., and more than 600 other cities across the world.[7][8][9][10][11] According to organizers, the march was a non-partisan movement to celebrate science and the role it plays in everyday lives.[12] The goals of the marches and rallies were to emphasize that science upholds the common good and to call for evidence-based policy in the public's best interest.[11][13] The March for Science organizers, estimated global attendance at 1.07 million, with 100,000 participants estimated for the main March in Washington, D.C., 70,000 in Boston, 60,000 in Chicago, 50,000 in Los Angeles, 50,000 in San Francisco,[14] 20,000 in Seattle, 14,000 in Phoenix, and 11,000 in Berlin.[15]

To date, the ocean has largely been treated as an afterthought in global climate strategies, sidelined in favor of more visible priorities like renewable energy and reducing carbon emissions. But ocean-based solutions are indispensable to the green transition and must be funded accordingly.

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

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

The sixth assessment report of the IPCC assessed that the Arctic is projected to be on average practically ice-free in September near mid-century under intermediate and high greenhouse gas emissions scenarios, though not under low emissions scenarios, based on simulations from the latest generation Coupled Model Intercomparison Project Phase 6 (CMIP6) models. Here we show, using an attribution analysis approach, that a dominant influence of greenhouse gas increases on Arctic sea ice area is detectable in three observational datasets in all months of the year, but is on average underestimated by CMIP6 models. By scaling models’ sea ice response to greenhouse gases to best match the observed trend in an approach validated in an imperfect model test, we project an ice-free Arctic in September under all scenarios considered. These results emphasize the profound impacts of greenhouse gas emissions on the Arctic, and demonstrate the importance of planning for and adapting to a seasonally ice-free Arctic in the near

SACRAMENTO -- Data from the California Energy Commission (CEC) shows that 59 percent of the state’s electricity came from renewable and zero-carbon sources in 2020. The CEC estimates that in 2020, 34.5 percent of the state’s retail electricity sales were served by Renewables Portfolio Standard (RPS)-eligible sources such as solar and wind. When sources of zero-carbon energy such as large hydroelectric generation and nuclear are included, 59 percent of the state’s retail electricity sales came from non-fossil fuel sources in 2020. In 2019, over 60 percent of the state’s electricity came from renewable and zero-carbon sources. The decrease in 2020 is due to decline in hydroelectric generation caused by severe drought, as well as pandemic-related delays to new renewable energy projects.

The lack of interest in climate adaptation and mitigation among national-security policymakers reflects a profound misunderstanding of the risks that climate change poses to global stability. To avert catastrophe, the international community must help the world’s most vulnerable countries strengthen their resilience.

More than 17 000 sites all over Europe are contaminated by the “forever chemicals” PFAS, an exclusive, months-long investigation from 18 European newsrooms shows. The investigation “The Forever Pollution Project” reveals an additional 21 000 presumptive contamination sites due to current or past industrial activity. The contamination revealed by this project spreads all over Europe.

The new study shows that every increment of sea level rise will cover more than twice as much land as older models predicted, and marks another advance in providing more accurate models of rising seas

Folks who do systems analysis have a great belief in “leverage points.” These are places within a complex system (a corporation, an economy, a living body, a city, an ecosystem) where a small shift in one thing can produce big changes in everything.

If 15 planned coal mining projects in Australia enter operation they would boost the country’s methane emissions from the dirtiest fossil fuel by nearly a fifth, according to an analysis from energy think tank Ember.

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.

With more governments embracing industrial policies to transform their economies, picking the right technologies to subsidize will become a key challenge. To navigate the minefield of entrenched interests, techno-hype, and political pressures, policymakers must embrace a mix of openness and caution.

New coal power projects are becoming “effectively uninsurable” outside China because so many insurance companies have ruled out support for them, a report has found. Recent commitments to stop underwriting coal by prominent US insurers AIG and Travelers have brought the number of coal insurance exit policies to 41, according to the latest industry scorecard by the climate campaign Insure Our Future.

Projected growth in rocket launches for space tourism, moon landings, and perhaps travel to According to new NOAA research published in the Journal of Geophysical Research Atmospheres, a 10-fold increase in hydrocarbon fueled launches, which is plausible within the next two decades based on recent trends in space traffic growth, would damage the ozone layer, and change atmospheric circulation patterns.

The world’s leading energy economist has warned against investing in large new oil and gas developments, which would have little impact on the current energy crisis and soaring fuel prices but spell devastation to the planet.

CCS - Carbon Capture and Storage: A research brief published by the Institute for Energy Economics and Financial Analysis (IEEFA) concludes that the abrupt recent shutdown of the Petra Nova coal-fired carbon capture plant in Texas should be seen as a strong signal for investors to avoid such projects.
