I’ve said it elsewhere than on Eratosphere (in upper case), and I shall say it again here. It deserves its own thread.
WE ARE ENTERING ANOTHER CYCLE OF POST-GLACIAL WARMING THAT IS BEYOND OUR CONTROL. WE MUST NOT ADD TO THAT TEMPERATURE RISE.
This is the evidence. Source: AAAS Science. Scroll down.
Eight glacial cycles. And we are slightly out of the most recent cold and into the heat. Figure 2 is the clearest. Don’t be scared by the wiggly lines. The present moment is at the left side. Each cycle takes a long time, like a hundred thousand years, give or take.
It’s very clear if you take the time to look Figure 2 over. Reading the text should give you a Stanford-Oxbridge eye-view of what is known for a fact. Dig in. We are a smart bunch.
Look at the left side of Figure 2. It’s very evident that we are entering a long high-temperature interglacial period. ALL THE MORE REASON TO CONTAIN MANMADE GLOBAL WARMING. The coal and oil interests and so on would absolutely seize on this to say that they aren’t responsible. But humans have to do everything they can to keep things tolerably livable and keep the Earth cool, with icecaps if possible. Cosmic cycles are no excuse for greed.
Here are some further links to info on what has happened so far to earth.
I find the ‘flipping’ very interesting.
(PM me for my thoughts about possible causes for these cycles.)
