There can be no denial of global warming...

...without first denying the physical science of the greenhouse effect:
Electromagnetic radiation includes Infrared Radiation (IR) and visible light. Both are absorbed by the surface of the Earth and converted to kinetic energy (heat). This heat is emitted back outward as thermal radiation aka IR. A significant amount of this IR is reabsorbed by the denser atmospheric gases such as water vapor, carbon dioxide, methane, nitrous oxide, etcetera. This excites their molecular structure and the resulting kinetic energy re-emits IR. Life on Earth is made possible by the capturing of enough IR to keep the biosphere warm enough to sustain life. As the heavier molecules in the atmosphere increase, the amount of IR also increases.
