Via NPR on the Arctic:
The Arctic has experienced the “most unprecedented transition in history” in terms of warming temperatures and melting ice, and those changes may be the cause of extreme weather around the globe, according to the National Oceanic and Atmospheric Administration’s 2018 Arctic Report Card.
The annual report released Tuesday says rapid warming over the past three decades has led to a 95 percent decline of the Arctic’s oldest and thickest ice. This research comes as world leaders convene at the U.N. climate summit in Poland this week where they are debating whether to embrace the findings of an October report by the International Panel on Climate Change.
The melting of sea ice is one of the most conspicuous examples of climate change in the Arctic, and scientists say it may be the catalyst for extreme environmental events across the world.
According to NOAA, the Arctic is warming at twice the rate of the rest of the globe, which is melting some of the region’s oldest ice.
