Climate change will reshape global economy

Oct 30, 2015 | News

(30 October 2015) – Unmitigated climate change is likely to reduce the income of an average person on Earth by roughly 23 percent in 2100, according to estimates contained in research published in the journal Nature that is co-authored by two University of California, Berkeley professors. An interactive map details the situation for each country.

The findings indicate climate change will widen global inequality, perhaps dramatically, because warming is good for cold countries, which tend to be richer, and more harmful for hot countries, which tend to be poorer.

In the researchers’ benchmark estimate, climate change will reduce average income in the poorest 40 percent of countries by 75 percent in 2100, while the richest 20 percent may experience slight gains.

The Nature paper focuses on effects of climate change via temperature, and does not include impacts via other consequences of climate change such as hurricanes or sea level rise. Detailed results and figures for each country are available for download online.
