re: #240 coquimbojoe

Is that the best that you have? Wikipedia? Really? Your just trying to get my goat, right?

Yes, most of the temp rise happened before the advent of tons of cars and the spread of industrialization. And what about the time before the 400k years? could it have been hotter? Hot enough to support say, giant lizards?

Come on do better than that. Hey, while you are at it check out this. And google sunspots vs climate temps or some such. Then go to Wikipedia to get the explanation as to why temperatures on Mars and Pluto and more are mimicking ours.
Wikipedia. Feh.

Where do I begin? Really, the facts are the facts. CO2 increases in the atmosphere in excess of 300 pp(million) (my mistake-it’s not billion) in the last 150 years are solely because of human activity. There is no other explanation. Have there been previous times when the Earth was hotter than it is now? Yes. Absolutely. But the last several million years has seen a steady state of glaciation/inter-glaciation cycles where both general temperature swings and CO2 cycles have been reasonably stable. Sunspot cycles are short wave, and we are in a low state at the moment (perhaps responsible for the slowing of warming in the northern hemisphere that we have seen for the last six years). But that cycle is about to swing back.

Question: If the global temperatures increase by 2 degrees during the next sunspot cycle, will you be convinced?
