al gore’s film an inconvenient truth documented the effect of ________ on climate temperature

In his opinion, the “real inconvenient truth is that science has no idea how much of recent warming is natural versus the result of human activities”.Īfter providing a succinct summary of the state of climate change science (5), Gerald North from Texas A&M University concludes the debate by stating that although there are some inaccuracies and exaggerations in the film, on the whole it represents mainstream scientific views on global warming. In his view, the film’s main omission is that while humans are almost certainly responsible for global warming, there are other natural causes of climate variability which the film does not address. In another paper (4), Roy Spencer from the University of Alabama in Huntsville also discredits the scientific validity of the documentary. He concludes that there are significant errors in the film, owing to alarmism and exaggeration, which give a false impression of both the current state of climate change and that the science is settled. This increases the film’s emotional impact but weakens the scientific argument.ĭavid Legates from the University of Delaware addresses assertions about trends in precipitation, floods, droughts and storms in particular (3). He comments that unfortunately, it neglects all information that can be gained from computer models, and instead relies entirely on past and current observational evidence. John Nielsen-Gammon from Texas A&M University also agrees that the main scientific argument presented in the movie is for the most part consistent with the weight of scientific evidence (2). The minor factual errors do not undermine the main message of the film, which explains the theory that increasing carbon dioxide causes a warming tendency in the lower atmosphere.

In the first opinion piece (1), Eric Steig from Washington University states that the film gets the fundamental science right. They also agree that its main weakness is that it tries to use individual extreme events, such as Hurricane Katrina, to prove the existence of global warming.

The papers in GeoJournal agree that it does an excellent job of raising public awareness of man-made global warming and explains why increased atmospheric concentrations of greenhouse gases lead to warming. An Inconvenient Truth is about Al Gore’s campaign to educate citizens about global warming and inspire them to take action.
