Global warming of more than 3°C this century may wipe 40% off the world's economy, new analysis reveals

A new analysis projects that global warming exceeding 3°C this century may decrease world GDP by 40%.
Economic models underestimated climate change impacts by failing to incorporate global supply chain disruptions.
The study, by the UNSW Institute for Climate Risk and Response, integrates climate forecasts to assess extreme weather consequences.
Previous models suggested a milder 11% GDP cut, whereas a 4°C temperature increase could reduce income by 40%.
The new projections highlight the economic case for faster decarbonization to limit warming to 1.7°C, aligning with the Paris Agreement.
