A, calm down. B, I've studied planetary geochemistry and I am well aware of Earth's overall geologic and climate history. There have been MAJOR fluctuations in Earth's climate, obviously, but the rate at which those changes occurred and the mechanisms that cause those changes (particularly when millions or hundreds of thousands of years is being considered) is considerably different than what causes changes over centuries or decades.
I was not addressing the hockey stick or the past 1000 years. I was talking about the post-glacial Holocene, the period we are in now.
Here's two illustrations:
Focus on the last interglacial to present:
Approximately the past 420,000 years:
The top graph encompasses approximately the final two rightmost horizontal grid ticks on the bottom graph. You can see how this whole past period of stability compares to the rest of the past 420,000 years in the bottom graph. It's almost impossible to find any period in the past 420,000 years when the temperature record has been this "calm" for this long.
I'm not trying to argue with you, I'm just trying to keep things in perspective. OK? These "Geology Pictures of the Week" I do are primarily for enjoyment and entertainment. I like to get serious elsewhere. But I'm always willing to discuss the climate change issues constructively, particularly when it comes to the science of the issue.
