Biomass is currently the EU’s largest renewable energy source, but climate strategies often focus on other energy sources. A comprehensive analysis, led by Chalmers University of Technology in Sweden, now shows that biomass is crucial for Europe's ability to reach its climate targets, as it can be used to produce fossil-free fuels and chemicals and also enables carbon dioxide removal from the atmosphere. If biomass were excluded from the European energy system, it would cost an extra 169 billion Euros per year – about the same as the cost of excluding wind power.

Honeybees are essential pollinators for agriculture and natural ecosystems. Stressors like climate change, habitat loss and pesticide exposure threaten their ability to forage for pollen, a critical resource for colony survival. Researchers in ACS’ Environmental Science & Technology demonstrate that an artificial intelligence (AI)-based monitoring system combined with a computer model can link the exposure of neonicotinoid pesticides on individual honeybees to the health of the whole colony.

Colder temperatures are linked with increased risk of diarrhea among Rohingya refugees in Bangladesh, emphasizing the need for climate-sensitive health strategies in refugee settings.

In a paper published in National Science Review, a Chinese team of scientists conducted an analysis on how changes in Arctic snow and ice cover affect cloud short-wave radiative effects, using satellite observations and climate model data. The study found that even under conditions where cloud properties remain unchanged, the melting of snow and ice can trigger an enhanced clouds’ short-wave cooling effect. The enhanced cooling effect can partially slow down the melting process, while it cannot reverse the overall decreasing trend of ice and snow.

 Americans are more likely to discuss climate change with family and friends if they feel worried or at risk, perceive society as supportive of pro-climate behaviors or see global warming depicted in the media, according to a study published April 17, 2025 in the open-access journal PLOS Climate by Margaret Orr from George Mason University College of Humanities and Social Sciences in Fairfax, Virginia, and colleagues.
