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.

Japan's government plans to temporarily lift restrictions on coal-fired power plants to address an energy crunch from the Middle East war. Officials presented the plan to a panel of experts, who approved it, the industry ministry said. The measure allows full operation of older, less efficient coal plants for a year starting in the new fiscal year from April.

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.

The Trump administration has opposed several international efforts to address climate change, including a proposed carbon tax on shipping emissions, a plastics production treaty, a UN resolution from Vanuatu, and IEA energy forecasts. These actions involved withdrawing from negotiations, issuing threats, and pressuring diplomatic partners. While some efforts faced delays, global renewable investments reached $2.3 trillion last year.

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.

King penguins on Possession Island are breeding earlier due to rising temperatures, leading to higher chick survival rates. While this has boosted chick numbers from 44 percent in 2000 to 62 percent in 2023, researchers warn that shifting food sources could threaten the population in the future. The changes highlight rapid environmental shifts in the Southern Ocean.
