The Arctic is warming faster than anywhere else on Earth, affecting people in the region, fish and wildlife they depend on for food, and their environment. This unprecedented change has ramifications far beyond the region for the global economy, weather, climate, sea level, trade and security. Watch the full Arctic Report 2017 AGU press conference…

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,…
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…
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…
