This document summarizes projections of future Arctic climate from the research of Zachary Labe. Sea ice extent is declining at a rate of 0.8 million km2 per decade as Arctic temperatures rise more than twice as fast as the global average. This warming amplifies in the Arctic (Arctic amplification) and is influencing weather patterns in northern mid-latitudes. Research indicates that continued sea ice loss will cause significant warming over the Arctic Ocean and a shift in the jet stream, with impacts on weather extremes. Understanding Arctic climate variability is important for assessing future local and remote responses to changes in the region.
