I am not a global warming sceptic. I accept that rising human-caused CO2 from fossil sources could 'change the climate'. The basic physics is there to support this view. But where is the evidence that the putative change would be large or damaging?

Climate is not responding to greenhouse gases in the way we thought it might. If increasing carbon dioxide is in fact increasing climate change, its impact is smaller than natural variation. People are being misled by people making money out of this.
