How is it that, in the face of overwhelming scientific evidence, there are still some who would deny the dangers of climate change?

The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.
