Rising sea surface temperature: towards ice-free Arctic summers and a changing marine food chain Document Actions

Abstract

Global sea surface temperature is approximately 1 degree C higher now than 140 years ago, and is one of the primary physical impacts of climate change. Sea surface temperature in European seas is increasing more rapidly than in the global oceans. Projections show the temperature increases will persist throughout this century. Ice-free summers are expected in the Arctic by the end of this century, if not earlier. Already, there is evidence that many marine ecosystems in European seas are affected by rising sea temperature.
