There can be no denial of global warming without first denying the physical science of the greenhouse effect:
“Visible light of the ‘electromagnetic spectrum’ passes through the atmosphere. It strikes and warms the surface of Earth as the result of being converted to infrared radiation (IR). Carbon dioxide and other greenhouse gases absorb and reradiate this heat. It is this heat index that is increased as the volume of greenhouse gases increases in the atmosphere.”
