Scientists are now saying that natural climate forces account for a “substantial” amount of the region’s warming in the past three decades.
A new study found that natural forces could account for as much as half of Arctic warming.
“Rapid Arctic warming and sea-ice reduction in the Arctic Ocean are widely attributed to anthropogenic climate change,” write climate scientists from the U.S., Australia and South Korea in a study that suggests that a “substantial portion of recent warming in the northeastern Canada and Greenland sector of the Arctic arises from unforced natural variability.”
“Whenever you start to look at local climate trends, you have to look at the internal variability as well as the human-induced variability,” co-author Mike Wallace with the University of Washington told CTV News. “The natural variability is huge.”
Sea ice has declined 2.6 percent per decade on average since the late 1970s, reports CTV News, but the area north of Greenland and the Canadian archipelago has been warming more quickly due to rain and wind patterns in the South Pacific — not man-made carbon dioxide emissions.
