Scientists at Chiba University in Japan have developed a new carbon material called viciazites that captures CO2 more efficiently and releases it at low temperatures. The material uses precisely arranged nitrogen groups to cut energy costs, potentially running on industrial waste heat. This breakthrough could make large-scale carbon capture more affordable.

Data centres powering artificial intelligence are causing land surface temperatures to rise by an average of 2°C near their locations, with extremes reaching 9.1°C, according to researchers at the University of Cambridge. The heat effects extend up to 10 kilometres away, potentially impacting more than 340 million people worldwide. The findings come from a study analysing satellite data over the past two decades.

The U.S. Supreme Court has agreed to review a Colorado Supreme Court ruling that let Boulder and Boulder County pursue state-law tort claims against ExxonMobil and Suncor over alleged climate-change harms, a case with potential implications for similar lawsuits around the country.

Researchers at Queen Mary University of London analyzed data from the BioTIME database and found species turnover in ecosystems has declined by a third since the mid-1970s. This challenges expectations that ecosystems would accelerate turnover in response to climate change and other pressures. Lead author Emmanuel Nwankwo described nature's self-repair mechanism as an engine grinding to a halt.

New research reveals that Brazil's cerrado savanna, often overshadowed by the Amazon rainforest, holds six times more carbon per hectare in its underground peat than the Amazon's biomass. This biodiverse ecosystem faces threats from climate change and expanding agribusiness. Protecting its wetlands could significantly aid global efforts to curb planet-warming gases.

A 60-year study of over 80,000 great tits in Oxford's Wytham Woods shows that cold snaps and heavy rain reduce nestling body mass and survival chances. Birds breeding earlier in the season appear better shielded from these effects. Moderate warm spells, however, can boost chick growth by enhancing food availability.
