A new study published in Science Advances finds that a leading theory explaining extreme weather events falls short when tested against simple climate models. The resonant Rossby wave mechanism, used to explain heatwaves, floods, and droughts, performs poorly in controlled tests. The finding calls into question current understanding of how climate change drives extreme events.
A spring heat dome has driven temperatures to record levels across Western Europe. The UK and France set all-time May records, with temperatures reaching levels usually seen in July or August. Scientists say climate change made the event at least five times more likely. At least seven heat-related deaths were reported in France. Authorities warn that infrastructure is not prepared for such early-season heat.
The UK recorded its hottest May day in history on May 26, with temperatures reaching 35.1C in London. The record was broken twice in two days, surpassing the previous high of 32.8C set in 1922. The Met Office confirmed the extreme heat is linked to climate change, as amber health alerts were issued across England.
A new study published in May 2026 warns that climate change could erode the air quality improvements the United States has achieved over the past 50 years of Clean Air Act regulation. Changes in temperature, wind patterns, and rainfall are expected to enhance ozone and particulate pollution, potentially cutting air quality gains in half by 2050.
The United Nations has warned that the next five years will smash global temperature records, with a high probability that one of them will be the hottest ever recorded. The warning comes as Brazil plans $75 million in Amazon highway investments, raising deforestation concerns.
The International Energy Agency projects global renewable energy capacity will surpass 10,000 gigawatts by 2030, tripling from 2023 levels. Solar and wind account for 95% of new additions. The report says the pace is still short of what is needed to meet Paris Agreement targets but marks a major acceleration.
International climate negotiations are underway with a focus on strengthening emissions reduction commitments. Countries are discussing enhanced targets for the coming decade and mechanisms for tracking progress. The talks include discussions about financial support for developing nations.
Grid operators reported that wind and solar power accounted for over 40 percent of electricity generation during recent weeks. Favorable weather conditions and increased capacity contributed to the record performance.
An international climate assessment report documented regional adaptation initiatives today. The report examines how different areas are responding to climate-related challenges. Findings show varied approaches to building climate resilience across geographic regions.
Pope Leo delivered a strong condemnation of companies earning what he called 'dizzying' profits from polluting industries, urging greater environmental responsibility. The address at the Vatican emphasized moral obligations to address climate change and protect vulnerable communities disproportionately affected by environmental degradation.
