Ice loss due to warming leads to warming due to ice loss: a vicious circle – Science Codex

The loss of huge ice masses can contribute to the warming that is causing this loss and further risks. A new study now quantifies this feedback by exploring long-term if-then-scenarios. If the Arctic summer sea-ice were to melt completely, a scenario that is likely to become reality at least temporarily within this century with ongoing greenhouse gas emissions from burning fossil fuels, this could eventually add roughly 0.2°C to global warming. It is, however, not in addition to IPCC projections…
