And again I just want to point out that we aren't denying the fact that the earth naturally heats and cools in cycles, what we are saying is that the rate at which it has heated up in the past decade is alarming.

What we are also saying is that the changes made to this climate could affect its natural cycles. There will be places in the world that will actually cool because of climate change, there will be places that do not show a temp change at all. Then there will be the prairies that actually see an INCREASE in precip as a result of this warming. But it doesn't change the fact that the climate has been changed, and the whole point of the Copenhagen conference is just to make sure that we don't pass the 2 C mark. The worst case scenario run by the ICPP is a 4 C change, thats with zero intervention, best case is a 2 C change.

Various climate models have been run for the past 100 years using recorded CO2 emissions and have been almost 100% accurate (100% in science is a very rare thing). Meaning that with the CO2 added in, it has matched our trend. Without the CO2, it hasn't.

GCM are very expensive, most countries only have one, except the States they have numerous models.

I am kind of curious, does anyone in this thread work in the Climate Change research field?

I look at this hacking as more of an act of desperation from the anti CC crowd. They are losing the argument, so they start attacking the data. If anything it is a compliment that we are doing our job right and need to just continue down this path.
