A global study finds billions of people live in "cooling poverty" as hot spells become more frequent and intense. Researchers call for low-cost, coordinated policies across housing, water, health and cities because air conditioning alone is not enough.

After the January 2022 eruption of Hunga Tonga–Hunga Ha’apai, satellites showed the volcanic plume helped destroy some methane. Researchers say sunlight on salt and ash likely created reactive chlorine that broke down methane, with implications for climate action.
An eight-year study used satellites and aircraft to track emissions at 98 California dairies. Researchers found digesters mostly reduced strong methane plumes but occasional large leaks and construction spikes mean careful monitoring is needed.
Scientists are watching El Niño because it can change weather globally and affect the Atlantic hurricane season. Many forecast models now see an increased chance of El Niño later this year, but its effect will depend on timing and ocean temperatures.
Researchers at Washington University studied detonation-made diamond dust for stratospheric aerosol injection. Simulations show carbon impurities and sp2 carbon cause absorption and reduce scattering, so these nanodiamonds are unlikely to cool the planet effectively.
A February report by Global Health Strategies and the African Union Commission finds that targeted climate adaptation finance delivered measurable benefits in Benin, Ethiopia and Namibia, improving flood protection, roads, market access and local decision-making.
At Super Bowl LX Bad Bunny used his halftime show to highlight Puerto Rico's fragile electricity grid. The island still faces frequent outages since Hurricane Maria, and efforts range from privatisation to community solar projects.
