Lake Sibinacocha is the 22nd highest lake in the world. Storms from the Amazon push up over the mountains, depositing snow on icecaps feeding high elevation lakes. Andean societies are among the most vulnerable to the impacts of climatic change on freshwater systems. Climate change will exacerbate water quality and quantity problems affecting millions of people. Warming in the Andes is occurring at rates nearly twice the global average. The effects on Andean lakes and ecosystems remain largely unknown, despite their importance to people and biodiversity. The objective of Grooms’s research is to assess the impacts of climate change on lakes.
