A comment to Romm..

"According to the 2007 Intergovernmental Panel on Climate Change (IPCC) report, water vapor in the global atmosphere has increased by about 5% over the 20th century, and 4% since 1970."

Just how much more moisture in the atmosphere does 4% represent? About 6 weeks ago on CP we were confronted with the same question. My estimate was about the volume of Lake Superior. comment #3.

A commenter came back, johna, #14, with an answer of about 1.5 times the volume of Lake Superior. I would quickly point out that that I am not a climate scientist nor to my knowledge is johna, which should catapult us both to the top of the deniers reference list but others should take our efforts with a grain of salt and maybe run the numbers themselves. Needles to say even if we are in the ball park we are looking at a whole lot of water that needs to come back out of the sky as rain but even snow in the winter when it is cold outside.
