"Other evidence of positive feedbacks is the large swings in climate that have occurred in the past such as during the ice age cycle. The changes in greenhouse gas levels, the albedo and the Milankovitch cycles are nowhere near enough to explain the ice ages."
Let me see, your argument is that C02 is going to kill us all, just like... well albedo can't, uhhh how about Milankovitch cycles... no? Well it must be those pesky greenhouse gasses, I don't know, dinosaurs breaking wind while driving their very large SUVs or something. NO??? Wait a minute what was your position again?
Steve's take on AGW -> C02 can't cause climate change even though it does.
Dude, get a band aid on that thing. :-)
No bandaid required. You've misunderstood.
It was a discussion about feedbacks to an initial source of warming. Some of the feedbacks are probably independent of the inital cause of warming (be it solar, albedo changes or greenhouse gases).
The fact that the climate was very sensitive to changes during the ice age is evidence that it may be very sensitive to changes due to CO2 warming.
Once again we are back to feedbacks and sensitive climate. The fact that the climate changed dramatically eons ago is not proof of ANYTHING. Except that climate does indeed change, sometimes dramatically. Earthshaking I agree. On the other hand, don't you think it is a stretch to say that the climate changed, and since we don't know why it must be PROOF that feedback and sensitive climate are the reason.
I have a hypothesis that explains the ice age. Are you ready? A long time ago an alien spacecraft flew by the earth. The aliens in question thought that earth would be a great place to ski. But alas there was not enough snow. To fix the problem, the aliens put up a sunshade that blocked all the sunlight from the earth. Imagine their surprise when the planet failed to cool. After further study it was determined that the cause of the failed cooling was that the future inhabitants of the planet had determined that the sun did not drive the planets climate, instead certain trace gasses were keeping the planet hot. Using unfathomably advanced technology the aliens overcame this difficulty and went skiing. When they were done. They left. And powered down their device. Thus causing the planet to slowly warm. Due entirely to the presence of the greenhouse gasses, of course. Subsequent ice ages were caused by the aliens returning to ski.
I have computer modeled this extensively and nothing that has ever happened or will happen is incompatible with my results. Should my premise or the results of my research come under attack by anyone. We can be sure that they are funded by the aliens themselves.
Now I understand that in the old days, I would be required to go through the tedious exercise of validating my model and maybe testing my hypothesis or god forbid sharing my source code, but that is old school. All of the hip scientists such as myself use the Post-Normal science concept which eliminates all that unnecessary work.
One last item. I have learned that the aliens will be returning to ski in a hundred years or so, I can stop them from plunging the planet into another ice age but it’s gonna cost you and you have to start paying now!
P.S. Look at that, time for my meds. ;D
