Study That Saw 62% Climate Hit to GDP Is Criticized by Peers

Scientists have challenged the findings of a flagship study that calculated severe climate change could cut global growth by about 62% this century, and which has been widely cited by policymakers and central banks.

An analysis of a paper published last April in Nature argues that anomalies in data for Uzbekistan, one of 83 counties examined in the original study, caused the results to overstate the potential economic hit. When Uzbekistan is removed, the projected losses by 2100 are reduced to 23%, in line with other similar modeling, according to the new article, published Wednesday in the same journal.
