Scientists from Boston College have found that tropical high-altitude glaciers have shrunk to record-low sizes over the past 11,700 years. The results of the study were published in the journal Science.
The study analyzed bedrock data from four glaciers in the Andes and found that their retreat rates were faster than previously reported.
Scientists have determined the chemical composition of bedrock exposed by recently retreating glaciers. The results show that the glaciers have only begun to melt in the last few decades. According to the researchers, this trend is linked to global warming.
Tropical glaciers are on the verge of extinction and their retreat could be much faster than expected, researchers warn.
