When it comes right down to it, I don't understand the hostility to science that climate change deniers embrace. Even if the deniers are absolutely right, and the 97% of scientists who agree that anthropogenic climate change is real are completely wrong, only good things can come out of trying to do something about carbon dioxide emissions: a reduction in pollution, more sources of sustainable energy, a loss of political power for despots who control fossil fuels, etc.
Where is the effing down side to those things?
Conversely, if the 97% of climate scientists are right (and we have no credible reason to believe otherwise), the consequences of ignoring the threat of global warming are grave.
The basis of climate change denial seems to be only contrarianism and nihilism.
