AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…
Published on YouTube Nov 21, 2013: The IPCC has produced a video on its Fifth Assessment Report (AR5). The first part on the Working Group I contribution to AR5 is now available. The other parts will be released with the successive approvals of the other two Working Group contributions and the Synthesis Report in the…

The ocean isshielding us from the worst effects of accelerating climate change by absorbing excess CO2 and heat from the atmosphere. The twin effects…
On September 27 2013 the IPCC released the WG1 report of the IPCC AR5 assessment. UN Secretary General Ban-Ki Moon addressed the IPCC at Stockholm on 27 September. He stated that “the heat is on. We must act”. US Secretary of State John Kerry responded to the report saying “This is yet another wakeup call: those who deny the science…

NASA: Drought Drives Decade-Long Decline in Plant Growth published 08.19.10 by Kathryn Hansen | Source Earth has done an ecological about-face: Global plant productivity that once flourished under warming temperatures and a lengthened growing season is now on the decline, struck by the stress of drought. NASA-funded researchers Maosheng Zhao and Steven Running, of the…
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,…

Broccoli, S. Frolking, J. N. Galloway, M. Heimann, C. Le Quere, S. Levitus and V. Ramaswamy | Source Climate sensitivity in its most basic form is…
Bio-energy with carbon capture and storage (BECCS) is a greenhouse gas mitigation technology which produces negative carbon dioxide emissions by combining biomass use with geologic carbon capture and storage. The concept of BECCS is drawn from the integration of trees and crops, which extract carbon dioxide (CO2) from the atmosphere as they grow, the use…
Excerpts from an episode of History Channel’s “Mega Disasters” series. This explores the paper published by Northwestern University’s Gregory Ryskin. His thesis: the oceans can produce massive eruptions of explosive methane gas. Methane distribution in the water column: Once released into the water column, methane is distributed by currents and aerobic methane oxidation by bacteria…
