It is not directly related, but it all is part of the puzzle.

And what the article addresses is merely a tiny part of the problem.

I am not a firm believer in absolute tipping points. But IF there is a tipping point, it is the thawing of the permafrost. If the permafrost thaws, (it already is!) the decomposition will lead to a MASSIVE release of greenhouse gasses, likely massively increasing our problems and making it a hundred times harder for us to mitigate the consequences.

Sequestering carbon (forests and saline wetlands being the most efficient way of doing this) and reduction of carbon emissions (wind energy perhaps being the best current way of doing this) are our only real solutions for now. Other things can help to varying degrees, but those two things are critical for any strategy of dealing with global warming.

The article you cite only emphasizes the need to sequester carbon and limit carbon emissions since it shows another feedback mechanism that will only make matters worse.
