“After decades of retreat, in the 1980s, many Karakoram glaciers suddenly ‘changed their mind.'”

According to Kenneth Hewitt, a glaciologist at Wilfrid Laurier University, Waterloo, in Canada, ‘I began to see glacier thickening and advancing that I had not observed in the 35 years of field work before.’ Hewitt called it the ‘Karakoram anomaly,’ and climate-change skeptics made the most of it.

New Report on Black Carbon in the Peruvian Andes

According to the study, tropical glacial melt is rapidly affecting water supplies and high concentrations of “light-absorbing particles on glacier surfaces” are part of the reason. Read the full report here.
