If You're Trekking to the North Pole... might want to bring a dinghy.

More meltdown here.

Your link, Laura, reminds me that while the Arctic is losing ice, and while Greenland is warming, that none of this is linear. Ice pressures on warming glaciers suggest a nonlinear slide into the oceans as lubrication and pressure increases.

Worse to my mind is what isn't said - the warming of the Arctic areas that area not necessarily covered by ice, but are areas of peat. What happens as that peat in North Canada and Siberia begins to warm and rot begins to happen as Arctic temperatures rise far faster than what we're seeing, say, here in Georgia?

Homeostasis and negative feedback? I don't think so. Positive feedback, the worst thing possible. That which lends credence to "tipping point" references.

Yeah. I thought I had posted something last year about the dominoes already beginning to fall, when I saw a news story about rapid thawing of permafrost in Siberia. So, when I saw a more recent one, I didn't bother to link it.

I've been trying to be positive, focus on what can be done, etc., but this is getting crazy. Sorry folks, I know you don't like bad news, but the news is bad.

The "good news"? Maybe the meltwater will shut down the Gulf Stream and freeze Europe, thus halting the Siberian thaw. Maybe that's what the adaptationists want - Europe shut down - less competition for North American industry. Never mind what other dominoes may fall in the process...

Arrgh. Gotta go, gotta write a sermon about how "the wisdom from above is first pure, then peaceable, gentle, willing to yield, full of mercy and good fruits, without a trace of partiality or hypocrisy." James 3:17
