UN admits 1.5°C target out of reach; adaptation costs to rise

The UN acknowledged that limiting global warming to 1.5°C above pre-industrial levels is no longer achievable, with some studies projecting the threshold could be exceeded as early as 2029. This marks a formal shift in the climate policy baseline, forcing governments to increase spending on adaptation to more frequent extreme weather events. The admission is a reversal of the Paris Agreement's core ambition, though the exact timing of overshoot remains uncertain.
