[asa] Lesson in science: Soot and global warming

On UcD Davescot argues that the IPCC ignores soot

He shows two figures, one from Hansen 2005 and one from IPCC. Can
anyone spot his error?

Hint: In IPCC the 0.1 refers to black carbon on snow, Hansen's 0.8
includes other effects. Where did these effects go in IPCC?

Look carefully, check and double check and come to realize that global
warming deniers could benefit from a more skeptical and critical
analysis of the arguments. A skeptic would say: what happened, a
global warming denier would say: See how the IPCC does not accurately
reflects science, I knew it.
Given the amount of peer review of IPCC, the latter stance seems silly
and indeed in this case it is.

I will provide the full answers later, I am just curious if people can
spot the problems.
