Climate change just a lot of hot air until proven otherwise

What I deny is that proof has been documented that humans are exacerbating the problem.

To the Editor,

Sure I am a denier. Not of climate change or of global warming – both have been around for untold millenia – what I deny is that proof has been documented that humans are exacerbating the problem.

The Intergovernmental Panel on Climate Change takes water vapour out of its calculations though it is a greenhouse gas, too, and increases in atmospheric concentration with rising temperatures.

I have seen no proof that man-made carbon dioxide causes global warming and no reason as to why water vapour concentrations are excluded from results.
