From Pieter Folkens:

Re: Climate change to go on for at least "1,000 years" (Jan. 9, 2011): The title of the article is strangely axiomatic. Climate change has been going on for what, four billion years? With that track record, it is expected to last another thousand years, probably longer. The study was based exclusively on nothing but "what if" computer modeling. The relevant apophthegm in science is: All computer models are wrong, some are useful. It is disingenuous for these researchers to present such studies as some form of data-based predictions. They are simply computer game playing with nothing more than "what if scenarios" and the work is certainly not rigorous science.
