21. Greenland Ice Core Record

According to the ice core records on Greenland, climate can change from glacial cold to interglacial warmth within a decade. That's with only slight perturbations and suggests the Earth's climate is far more sensitive than we thought. If you create a low salinity ocean in the North Atlantic from Greenlandic Ice Cap melt, under the right conditions you can freeze portions of the surrounding ocean, cut off the Gulf Stream flow to northern Europe and impose ice age conditions even though you've got CO2 level increasing and in excess of "normal" interglacial levels. How long that would last is anyone's guess however unlikely that were to occur.

As I said before, the climate change process is probably not going to impact us as much as the impact climate change will have on our economic system. There is an interesting theory by Kyle Harper that the collapse of the western Roman imperial system was in large part due to climate change. While I don't think the climate perturbations he is pushing are enough to account for what happened it's an interesting theory with some parallels to our current dilemma.

And unfortunately many and I mean right wingers, don't care. dewsgirl Dec 2019 #1
