James Hansen explains Earth energy imbalance from anthropogenic forcing and the urgency to act, because of the climate inertia. Earth’s Energy Imbalance By James Hansen, Makiko Sato, Pushker Kharecha and Karina von Schuckmann — January 2012   Deployment of an international array of Argo floats, measuring ocean heat content to a depth of 2000 m,…

Arctic Death Spiral – Evolution to July 2013

Published on YouTube Aug 12, 2013: This is a visualization of the Arctic Death Spiral showing the evolution of the volume of sea-ice over time from 1979 to July 2013. Pitch of the notes are proportional to the average sea-ice volume for each month. Spectral filters are derived from the average sea-ice volume for each…

West Antarctic rapid glacier retreat may be exceptional during the Holocene

Ice loss from the marine-based, potentially unstable West Antarctic Ice Sheet (WAIS) contributes to current sea-level rise and may raise sea level by ≤3.3 m or even ≤5 m in the future. Over the past few decades, glaciers draining the WAIS into the Amundsen Sea Embayment (ASE) have shown accelerated ice flow, rapid thinning, and…
