Reply #4: I think that happened last summer

[Dogmudgeon]

I tracked Arctic temperatures pretty well. I think the "tipping point" for Arctic tundra disruption was hit last summer. A huge area of peat bogs and microbes was unfrozen for nearly four months, the first time in probably several thousand years. The area included major parts of Northern Sweden, Northern Finalnd, Northern Russia, Alaska, Nunavut, Baffin Island, and Greenland.

There are still several major ecosystems that are stable enough to compensate somewhat, but they are running out of time. It is probably too late to prevent the coming climate change, but it is NOT too late to get ready for it.

Climate change doesn't have to be a disaster -- merely a catastrophe (in the mathematical sense).
