ARCTIC REPORT CARD: “The Arctic is undergoing its most unprecedented transition in human history. We’re seeing this continued increase of warmth pervading across the entire Arctic system,” said Dr. Emily Osborne, an official with the National Oceanic and Atmospheric Administration (December 2018)
“In 2018, warming air and ocean temperatures continued to drive broad long-term change across the polar region, pushing the Arctic into uncharted territory,” stated Emily Osborne. The warmer Arctic air causes the jet stream to become “sluggish and unusually wavy”. That has possible connections to extreme weather events elsewhere on the globe, including last winter’s severe storms in the United States and a bitter cold spell in Europe known as the “Beast From the East.” The rapid warming in the upper north, known as Arctic amplification, is tied to many factors.
