Climate Progress quote: "NSF issues world a wake-up call: “Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming.” Science 5 March 2010: Vol. 327 no. 5970 pp. 1246-1250 DOI: 10.1126/science.1182221 Report Extensive Methane Venting to the Atmosphere from Sediments of the East Siberian Arctic Shelf http://www.sciencemag.org/content/327/5970/1246.abstract Climate…
The big deal here is that the PETM (Pleistocene Eocene Thermal Maximum) was a massive ocean extinction event. There was a minor extinction event on land, but the big deal happened in the world’s oceans. The global temperature change was only about five degrees and it was short lived (20,000 years.) What likely happened was,…
Part of Dr. Walters research involves winter time excursions to frozen over permafrost melt lakes to measure the trapped methane beneath the ice. She recently returned from her Siberia project and reported that the size of the melt lakes had increased five times in her two years absence. Make sure to see her research videos….
Dr. Katey Walter, from the University of Fairbanks, sees methane like many climate scientists these days. The warming across the planet is concentrated at the poles because of what is called polar amplification. This means that the Arctic is warming even more than the rest of the Earth. In many places the Arctic has already…
February 15, 2009 More from Fields Below – Astonishing news about Permafrost Catastrophic permafrost melt is one of the likely abrupt climate change feedback scenarios. Major permafrost melt has already happened and the melt rate is increasing rapidly. Hundreds of thousands of years of frozen, partially decomposed tundra is at risk of thawing. Scientists aren’t…
This is a classic example of a scientist, or in this case, a team of scientists, understating the obvious. It is a product of the industry of science, a product of the ultra conservative scientists themselves. What they have "discovered" are dramatic affects of melting permafrost in the Arctic. It appears that permafrost melt on…
