Ebert loved Gore's "documentary".
---
Ebert is a liberal. He is wrong about the science validating Gore's movie, which was hyperbolized scaremongering ...
From Gregg Easterbrook's (environmentalist and non-GW skeptic) review of Gore's movie:
http://www.slate.com/id/2142319/
"The picture the movie paints is always worst-case scenario. Considering the multiple times Gore has given his greenhouse slide show (he says "thousands"), it's jarring that the movie was not scrubbed for factual precision. For instance, this 2005 joint statement by the science academies of the Western nations, including the National Academy of Sciences, warns of sea-level rise of four to 35 inches in the 21st century; this amount of possible sea-level rise is current consensus science.
Yet An Inconvenient Truth asserts that a sea-level rise of 20 feet is a realistic short-term prospect. Gore says the entire Greenland and Antarctic ice sheets could melt rapidly; the film then jumps to animation of Manhattan flooded. Well, all that ice might melt really fast, and a UFO might land in London, too. The most recent major study of ice in the geologic past found that about 130,000 years ago the seas were "several meters above modern levels" and that polar temperatures sufficient to cause a several-meter sea-level rise may eventually result from artificial global warming. The latest major study of austral land ice detected a thawing rate that would add two to three inches to sea level during this century. Such findings are among the arguments that something serious is going on with Earth's climate. But the science-consensus forecast about sea-level rise is plenty bad enough. Why does An Inconvenient Truth use disaster-movie speculation?"
I no longer patronize anything this far left liberal and his half-wit sidekick (Richard Roeper) produce.
Ebert is a lib; his views have been expressed many times about reviewing other films of his political beliefs. But when all other film critic snobs were thumbing their elitist noses at "The Passion of the Christ", Ebert praised the film, saying it was by far the best movie of 2004, and one of the greatest achievments in cinematic history.
