Abstract

What drives hydroclimate changes in tropical regions is not well known. Here, the authors present a 12,000 year long precipitation record from Guetemala which shows that exceeding a threshold in sea surface temperatures caused Central American rainfall to change from a dry to an active convective regime around 9000 years ago.
