These jobs at risk are equivalent to a quarter of the total workforce worldwide today.
The study, which was presented at the United Nations Climate Conference (COP27) in the Egyptian resort of Sharm el-Sheikh on Tuesday, said: "The risk of [loss] of jobs is greatest in the Asia-Pacific and Africa region, just as it is in the case of the possibility of creating additional jobs."
According to the study, the jobs most affected by climate change are those in agriculture, energy, mining, industry, transportation, and construction.
