Hotter Days Will Drive Global Inequality

To predict just how various countries might suffer or benefit, a team of scientists at Stanford and the University of California, Berkeley, have turned to historical records of how temperature affects key aspects of the economy. When they use this data to estimate how various countries will fare with a warming planet, the news isn’t good.

The average global income is predicted to be 23 percent less by the end of the century than it would be without climate change. But the effects of a hotter world will be shared very unevenly, with a number of northern countries, including Russia and much of Europe, benefiting from the rising temperatures. The uneven impact of the warming “could mean a massive restructuring of the global economy,” says Solomon Hsiang, a professor at the Goldman School of Public Policy at Berkeley, one of the researchers who have painstakingly documented the historical impact of temperature. Even by 2050 (see map), the variation in the economic fates of countries is striking.

Because poorer countries, including those in much of South America and Africa, already tend to be far hotter than what’s ideal for economic growth, the effect of rising temperatures will be particularly damaging to them. Average income for the world’s poorest 60 percent of people by century’s end will be 70 percent below what it would have been without climate change, conclude Hsiang and his coauthors in a recent Nature paper. The result of the rising temperatures, he says, “will be a huge redistribution of wealth from the global poor to the wealthy.”
