Before revision: The downward trend in Arctic sea ice is a key factor determining the pace and intensity of future global climate change; moreover, declines in sea ice can have a wide range of additional environmental and economic consequences  . Based on several decades of satellite data, we provide statistical forecasts of Arctic sea ice extent during the rest of this century.
