Ignore the underlying science at your own risk

Rating: 9/10 (2 November 2011)

The scientific evidence for the basis of the movie has been muddied by a propaganda campaign by the oil and gas industry to continue business as usual. The fact of the matter is that the atmosphere is a "closed system" and people have been adding cultural air pollution for decades.
It is true that heavy sun spot activity or vulcanism can "trump" incremental changes from man's pollution of the atmosphere. However, what is being added to the atmosphere IS not helping the climate but making it much more difficult to predict the weather. Thus, it is difficult for the weather guessers to comfortably predict from season to season what is happening. My "hat is off" to Roland Emmerich for raising the issue in this film to cause the discussion. I do not know if the variability will cause a sudden change but there is evidence in the fossil record that things can happen very quickly.
They fact of the matter is if the ocean currents shut down as predicted in the film, a lot of folks are not just going to be inconvenienced. They will simply die just as quickly as the mammoths who died with butter cups in their mouths. Sign this from a geologist who has thought about this for decades.
