Bare with me, as this may be a long post. I think I'll actually break this into two parts to present all of the information.
Now, we have to define our terms and set the record straight. There is undeniable evidence that the Earth has been getting warmer. This is not in doubt. What is in doubt is man's role in global climate change. Currently, according to Al Gore and the group of 1200 UN scientists, global warming is caused by CO2. This means, in simple terms, a rise in CO2 will lead to a direct rise in temperature. This is Gore's whole premise. No other possibilities seem to be discussed, at least none that made it to any of the larger news sources.
Gore offers two major items as his evidence: the Vostok ice core data charts and the IPCC temperature models. Based on these two pieces of evidence, Gore suggests that there will be "catastrophic consequences" from global warming. So, to combat these consequences and slow or reverse global warming, we (humans) have to change our habits.
However, there are a few holes in Gore's hypothesis.
First is the weakness of the IPCC temperature model. Apparently, the models were not calibrated to our current conditions. This means the models were compromised. In addition, the weakness of the interpretation of the model information, specifically the 7th chapter dealing with "atmospheric processes and feedback" that affect global temperatures.
Interesting that the model has some weaknesses. It's almost like they wanted the model to predict bad tidings for some reason.
More to come later.
