Alex Smith talks with the American scientist David Archer and the author of "The Long Thaw" on Radio Ecoshock.
Methane is generally said to be 20 times more powerful than CO2 when it comes to trapping solar heat. That is really just an average, because when it first emerges, methane can be as much as 75 times more powerful. It degrades more quickly than C02, becoming less potent in 10 years. But methane degrades into CO2, continuing the greenhouse gases for up to 100,000 years, according to Dr. David Archer.

Wonderful interview. Archer has some great posts in RealClimate - look for titles containing "Methane" Great discussions in the comments sections too.
