Scientists report increases in methane releases in Alaska, Siberia; accelerated climate change could result
Justin Gillis has a disturbing front page article in the New York Times Saturday about the growing appearance of methane gas bubbles from the permafrost in central Alaska.
Methane is formed when plants decay under water, and traps much more heat (as a greenhouse gas) than does carbon dioxide.

This may confirm the “worst fears” of climate change scientists, who warn that quick release of methane (as from hydrates) could escalate to planetary catastrophe. Climate change could become a runaway train, self-generating development. Is that what happened to Venus maybe just a billion years ago?
This YouTube video, about a year old, talks about the East Siberian ice shelf releasing methane.

There’s a nickname for all this, “farting ice”.
Sarah Palin doesn’t seem to take it seriously.
