World GDP To Drop By 18% If There Is No Action Against Climate Change

Global gross domestic product will fall by 18% if no action is taken on climate change and global temperatures rise by 3.2 degrees Celsius, according to a report by Swiss reinsurer Swiss Re AG. The report was conducted by stress-testing the world’s 48 major economies, which account for 90% of global GDP, against four possible scenarios, with 18 % declines in the most pessimistic and 4 % in the most optimistic – achieving a global temperature rise of no more than 2 degrees Celsius, in line with the Paris Agreement.
