“If we can limit our emissions, then the permafrost region will release less carbon to the atmosphere, there is a curve – it’s not a all or nothing question.” Ben Abbott

One of the most feared of climate change “feedbacks” is the potential release of greenhouse gases by melting arctic permafrost soils. New research indicates a critical threshold of that feedback effect could be closer than we once thought. http://www.scientificamerican.com/art…

    Um, so what happened to the methane from all of the permafrost that melted since the end of the last glaciation 20,000 years ago? It entered the atmosphere and basically nothing happened. The proof is there everyday.

    And how is today’s melting different from the past? It isn’t, its merely a continuation of the past. Claiming that it is caused by humans is little more than wishful thinking.
