Depending on what article you read, methane is 20 to 25 times more efficient at trapping heat than carbon. As the environment warms, the permafrost is melted releasing more methane which warms the environment further melting more permafrost, etcetera.
If you haven't watched the "How it all Ends" series I linked to eariler, the gradual change in climate we used to believe would take place over hundreds of years isn't the concern. It is the cataclysmic and sudden shift from feedback loops becoming their own self sustaining engine that will get us.
It would be a bit more believable if it was written as a "sudden shift". Cataclysmic seems a bit over the top--like you're trying too hard.
Every day the temperature increase is an order of magnitude higher than that of the most pessimistic climate science projections. If the positive dynamic feedback was a simple as you've claimed we'd see runaway temperatures today.
Thus, either there is also negative feedback (attenuating the GHG effects), or the positive feedback is incompletely understood. Or both.
Off the air for a few days. best to all.
