Global warming will kill 83 million people by 2100: new study

A population equivalent to that of Germany – 83 million people – could be killed by 2100 due to rising temperatures caused by greenhouse gas emissions, according to a new study that could influence how markets assess carbon pollution.

Research from the Earth Institute at Columbia University introduces a new measure to help businesses and governments assess the damage caused by climate change this century. Accounting for the “deadly cost of carbon” could give polluters new reasons to clean up by dramatically increasing the cost of emissions.
