Cold snap in the tropics: How tropical glaciers respond to cooling periods

25 agosto 2014

Tropical glaciers have responded to episodes of cooling in Greenland and the Antarctic over the past 20,000 years, according to a study that covers 21 Andean glaciers. As elsewhere on the planet, tropical glaciers (located on either side of the equator between 23°N and 23°S) have been retreating since the Last Glacial Maximum around 20,000 years ago. This retreat has been interrupted by stillstands and re-advances, although a detailed chronology of these events in tropical regions remained unclear until now.
