Human influence detected in global rainfall patterns

Greenhouse gases emitted by human activity are strengthening storms and causing rain bands and dry zones to move poleward, scientists report November 11 in the Proceedings of the National Academy of Sciences.


Climate simulations have long forecast that climate change caused by greenhouse gas emissions will make rain heavier and more intense, while also pushing storms and deserts away from the equator. Observed climate patterns that match these predictions are called "fingerprints" of human ac...
