CAMBRIDGE, Mass.–A rising tide is said to lift all boats. Rising global temperatures, however, may lead to increased disparities between rich and poor countries, according to a recent MIT economic analysis of the impact of climate change on growth.

After examining worldwide climate and economic data from 1950 to 2003, Benjamin A. Olken, associate professor in the Department of Economics, concludes that a 1 degree Celsius rise in temperature in a given year reduces economic growth by an average of 1.1 percentage points in the world’s poor countries but has no measurable effect in rich countries.

Olken says his research suggests higher temperatures will be disproportionately bad for the economic growth of poor countries compared to rich countries.
