Leaking Siberian ice raises a tricky climate issue

CHERSKY, Russia – The Russian scientist shuffles across the frozen lake, scuffing aside ankle-deep snow until he finds a cluster of bubbles trapped under the ice. With a cigarette lighter in one hand and a knife in the other, he lances the ice like a blister. Methane whooshes out and bursts into a thin blue flame.

Gas locked inside Siberia's frozen soil and under its lakes has been seeping out since the end of the last ice age 10,000 years ago. But in the past few decades, as the Earth has warmed, the icy ground has begun thawing more rapidly, accelerating the release of methane — a greenhouse gas 23 times more powerful than carbon dioxide — at a perilous rate.

Some scientists believe the thawing of permafrost could become the epicenter of climate change. They say 1.5 trillion tons of carbon, locked inside icebound earth since the age of mammoths, is a climate time bomb waiting to explode if released into the atmosphere.

"Here, total carbon storage is like all the rain forests of our planet put together," says the scientist, Sergey Zimov — "here" being the endless sweep of snow and ice stretching toward Siberia's gray horizon, as seen from Zimov's research facility nearly 350 kilometers (220 miles) above the Arctic Circle...

1. I think there is nothing we can do at this point to avoid a global catastrophy. The rich will be OK.

It's the poor and badly situated (Africa) that will pay the price for capitalism.

I guess I should have put TSA in the title.

8. And we're up in arms about TSA groping.

I really can't put in a more polite way. I'm just appalled at how short sighted we are. As the planet is dissolving under our feet, we all want to run around in airplanes and cars. Where is the sense of responsibility? It's as if asking that question is the most insulting thing one can say. I just can't believe it. Why aren't people curbing their habits?

That is all rhetorical. So save your keystrokes.
