A Scientific Guide to the 'Skeptics Handbook'

The Skeptics Handbook asks "what evidence is there that more CO2 forces temperatures up further?" It then lays out 4 arguments: the greenhouse signature is missing, CO2 lags temperature, it's not warming and the CO2 effect is saturated. The great irony of the 'Skeptics Handbook' is when you examine these 4 arguments and the full body of empirical evidence that goes with them, what you actually find is the evidence that human CO2 emissions are causing global warming. The guide is freely available as an A5 PDF or printable A4 PDF that can be folded into an A5 booklet.

The human fingerprints on climate change

The Scientific Guide examines 4 human fingerprints on climate change. Click on any fingerprint for more detailed information.

		Cooling stratosphere/warming troposphere As CO2 stops heat from reaching the upper atmosphere, we expect to see a warming lower atmosphere and cooling upper atmosphere.
		Less heat is escaping to space Satellites measure more heat being trapped by CO2. Combined with ice core records, this is evidence for positive feedback.
		Nights warming faster than days The number of warm nights are increasing faster than warm days. This is another effect of greenhouse warming.
		More heat returning to Earth Confirming the satellite data, surface measurements find more heat returning to Earth.
