climate skeptics

Climate skeptics are contrarians who challenge the evidence that human activities such as deforestation and human behaviors that result in more greenhouse gases like carbon dioxide are causing changes in our planet's climate that may prove devastating and irreversible.

The core of the consensus view of the scientific communityPhote courtesy of NASA has been stated by the Intergovernmental Panel on Climate Change (IPCC) in its "Climate Change 2007" report. The core of the consensus view is, among other things, that global warming is happening and that human activities are contributing significantly to the climate change, which is affecting such things as the intensity of hurricanes and rising sea levels. It would be absurd, of course, to claim that the consensus of the scientific community agrees with everything in the IPCC reports, especially since not all the scientists who worked on those reports agree with each other on every item.

In one important respect, it doesn't matter what the scientific consensus on climate change is, since what matters is what policies the powerful governments of the world institute, and those governments tend to ignore science. If they don't ignore the science, they find contrarians to argue that the consensus isn't absolutely certain* and therefore we're justified in continuing along our current course. Powerful governments tend to listen to scientists when the consensus science is compatible with their policies or when it is required because of catastrophes that have already occurred or are about to occur.

BBC News has posted 10 of the arguments most often made against the IPCC consensus, as well as some of the counter-arguments made by scientists who agree with the IPCC: Climate Skepticism: the Top 10.
