One thing I haven't had a satisfactory answer to is this: Why is 1979 deemed so important? Why is the the norm only taken from 1979? Who says that what we're experiencing over the past 500 years is 'normal'?
the vostok ice core showed that the temperatures we're experiencing are certainly not normal in the context of the earth's past 400,000 years.
The average temperature for the past 400,000 years, which is shown by that ice core sample, shows we're currently at an temperature well above the mean. so why 1979??
We all know that if the earth hits an ice age we're buggered anyway.
what i think i'm trying to get at is ultimately, who is honestly arrogant enough to say that the planet now must stay withini a narrow band of temperatures, when it has changed so much in the past. Surely noone really thinks that we're going to be able to stop any apparent warming now, and then stop cooling later on??
