‘Glacial darkening’ at a rapid pace is melting the world’s ice, quickly
In Canada, wildfires linked to climate change are leaving deposits on glaciers, creating habitats for algae and accelerating the warming process in a feedback loop
Geneva — Glaciers will melt faster than current models on climate change account for as algae blooms colonise them and reduce their ability to reflect the sun's heat, scientists studying glaciers said.
“Glacial darkening” is where deep purple, bulbous algae sprout on a layer of naturally occurring dust mixed with soot from air pollution and forest fires. Their presence has been confirmed for decades but as temperatures rise, more algae are thriving on the ice surface, staining glaciers the world over...
