Illustration of atmospheric Hadley cell under present-day conditions (left). Subtropical warming leads to a weakening of the Hadley cell (right), less clouds in most of the tropics, a reduction in the upwelling of cold ocean water, and a resulting increase in tropical temperatures. This process explains the accelerated tropical warming found in climate models in response to increase greenhouse gas emissions.
