New study calculates climate change's economic bite will hit about $38 trillion a year by 2049

Climate change will reduce future global income by about 19% in the next 25 years compared to a fictional world that's not warming, with the poorest areas and those least responsible for heating the atmosphere taking the biggest monetary hit, a new study said.

Climate change's economic bite in how much people make is already locked in at about $38 trillion a year by 2049, according to Wednesday's study in the journal Nature by researchers at Germany's Potsdam Institute for Climate Impact Research. By 2100 the financial cost could hit twice what previous studies estimate.

“Our analysis shows that climate change will cause massive economic damages within the next 25 years in almost all countries around the world, also in highly-developed ones such as Germany and the U.S., with a projected median income reduction of 11% each and France with 13%,” said study co-author Leonie Wenz, a climate scientist and economist.

These damages are compared to a baseline of no climate change and are then applied against overall expected global growth in gross domestic product, said study lead author Max Kotz, a climate scientist. So while it's 19% globally less than it could have been with no climate change, in most places, income will still grow, just not as much because of warmer temperatures.
