Global warming found to be culprit for flood risk in Peruvian Andes
As the planet warms, glaciers are retreating and causing changes in the world’s mountain water systems. For the first time, scientists at the University of Oxford and the University of Washington have directly linked human-induced climate change to the risk of flooding from a glacial lake known as one of the world’s greatest flood risks.
The study examined the case of Lake Palcacocha in the Peruvian Andes, which could cause flooding with devastating consequences for 120,000 residents in the city of Huaraz.
The new study first calculated the role of human emissions in the observed temperature increase since the start of the industrial era around Palcaraju Glacier. It finds that human activity is responsible for 95% of the observed 1 degree Celsius (1.8 degrees Fahrenheit) warming in this region since 1880.
