Abstract: | Al Gore’s movie An Inconvenient Truth gives a variety of unusually biased interpretations of the state of climate science and global warming theory. These cover
a wide range of natural events and processes which could potentially be impacted by global warming, but which the movie misrepresents
as clear examples of the human influence on climate. A few examples include the mixing up of cause and effect in his graphical
portrayal of temperature and carbon dioxide variations over hundreds of thousands of years; the repeated depiction of ice
calving from glaciers as a sign of global warming; the implication that Hurricane Katrina was the fault of humans; and the
particularly extreme view that the Greenland ice sheet will melt, flooding coastal cities worldwide. Ultimately, all of these
are related to the widespread perception that scientists have uniquely tied global warming to anthropogenic greenhouse gas
emissions. The real inconvenient truth is that science has no idea how much of recent warming is natural versus the result
of human activities. |
