A new research paper by American and European climate scientists focused on Arctic warming published Monday reveals that the “smoking gun” when it comes to changes in the world’s northern polar region is rapidly warming air temperatures that are having—and will continue to have—massive and negative impacts across the globe.
The new paper—titled “Key Indicators of Arctic Climate Change: 1971–2017“—is the work of scientists at the International Arctic Research Center at the University of Alaska Fairbanks and the Geological Survey of Denmark and Greenland in Copenhagen (GUES).
“The Arctic system is trending away from its 20th century state and into an unprecedented state, with implications not only within but beyond the Arctic.” —Jason Box, GUES
“The Arctic system is trending away from its 20th century state and into an unprecedented state, with implications not only within but beyond the Arctic,” said Jason Box of the GUES, lead author of the study. “Because the Arctic atmosphere is warming faster than the rest of the world, weather patterns across Europe, North America, and Asia are becoming more persistent, leading to extreme weather conditions. Another example is the disruption of the ocean circulation that can further destabilize climate: for example, cooling across northwestern Europe and strengthening of storms.”
John Walsh, chief scientist at AUF’s research center, was the one who called arctic air tempertures the “smoking gun” discovered during the research—a finding the team did not necessarily anticipate.
