Specifically, the Q-and-As confirm what many skeptics have long suspected:
- Neither the rate nor magnitude of recent warming is exceptional.
- There was no significant warming from 1998-2009. According to the IPCC we should have seen a global temperature increase of at least 0.2°C per decade.
- The IPCC models may have overestimated the climate sensitivity for greenhouse gases, underestimated natural variability, or both.
- This also suggests that there is a systematic upward bias in the impacts estimates based on these models just from this factor alone.
- The logic behind attribution of current warming to well-mixed man-made greenhouse gases is faulty.
- The science is not settled, however unsettling that might be.
- There is a tendency in the IPCC reports to leave out inconvenient findings, especially in the part(s) most likely to be read by policy makers.
