Non-local impacts of observed and projected high-latitude climate change

The high latitudes have been displaying some of the most dramatic signs of climate change in recent decades. Both northern and southern high latitudes are projected to warm more than the global mean and lose ice mass considerably by the end of the 21st century. I will highlight studies that quantify the remote impact of sea ice loss, Southern Ocean (SO) surface warming, and Antarctic ice sheet melt. A large body of literature has been dedicated to study the impact of Arctic sea ice loss on the mid-latitude weather. More recently, growing attention has been given to the remote impact of the SO and Antarctic ice sheet meltwater. Given the emerging SO warming and Antarctic ice melt in recent observations, as well as the systematic climate model biases in SO surface temperature trends, collaborative community efforts are poised for progress.
