Plant Productivity Reduction with Climate Change

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…

Methane hydrate destabilization a potential scenario

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…

Methane release from the East Siberian Arctic Shelf and the Potential for Abrupt Climate Change

A Mechanism for Shallow Methane Hydrate Dissociation

I previously looked at the science and commercial usage of Methane Hydrate, at freshwater influx in the Arctic Circle and asked  Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean? This post covers: Identification of possible mechanism which could eventually release vast quantities of shallow Methane Hydrate…
