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.
