Myth: Climate sensitivity is too low
Since the effect of CO2 on temperature is logarithmic, we have already seen most of the warming that can possibly happen and any future increase will be pretty negligible. There is nothing to worry about.
- Observations Show Climate Sensitivity Is Not Very High Coby Beck, "How to talk to a Climate Skeptic", 27 June 2006
Doubling the amount of CO2 in the atmosphere will increase temperatures far less than the IPCC say it will.
- Climate sensitivity is low John Cook, Skeptical Science (undated)
Climate sensitivity is too uncertain, we cannot know what changes might happen.
- The certainty of uncertainty RealClimate, 26 October 2007
No one doubts that there are uncertainties in both models and observations. Future changes could be better than we expect, but equally they could be worse than we expect:
