Thanks for your civility and thoughtfulness, for
shedding new
light on things I thought I'd already figured out, for opening cans of worms that often made the
discussions much
more interesting than my original posts, for listening to my occasional rants, and for bringing your own unique backgrounds, studies, experiences, and links to the conversations.
The
discussion of climate sensitivity in the recently released Fifth Assessment Review of the Intergovernmental Panel
on Climate Change (IPCC)
sheds more light on this parameter, which turns out not to be known with certainty.
