Common Denier Arguments

Deniers continue to repeat several arguments long after they have been debunked by experts. In the past, deniers have contended (and some continue to argue) that the world is not warming. Overwhelming amounts of data from throughout the world have made that argument so fallacious that the deniers have now shifted their contention; claiming that humans are not responsible for the warming. Because the basic physics of greenhouse gases has been well-established, along with the fact that human activity has generated billions of tons of greenhouse gases, make this argument untenable, the denier argument has shifted further. Some deniers now concede that warming will occur, but that impacts will be minimal, and some argue that even if climate change will have impacts, it will cost too much for us to do anything about it. Of course, the cost of failing to act will be much higher.

What follows are some common denier arguments and responses from leading scientific organizations, including the Intergovernmental Panel on Climate Change   (IPCC), the US National Academy of Sciences  , and the United Kingdom’s science academy, the Royal Society  .
