Two small paragraphs in the news " Millions of tons of methane will surface in the Arctic " (please, read the news): i) Methane now accounts for between 4 to 9% of greenhouse , well below the effect of CO2 (from 9 to 26%). However, its ability to absorb heat is about 25 times higher than that of CO2, so its lower contribution to global warming is because there is less of it in the air (while counting some 75 times more CO2 than methane). Conclusion: escaping tons of methane were buried in frozen ground is not going to help improve the situation of climate change.
ii) This was known in recent years (Nature 443, 71-75, 2006: Methane bubbling from Siberian thaw lakes as a positive feedback to climate warming )
From here a greeting to my Jiminy Cricket . ;-)
