Virga may cool as it falls and absorb latent heat as it becomes vapor again, but there is only virga below clouds. Condensation and re-evaporation may be more considerable (quantity) within clouds, but still probably a small part of the total convection.

You don't? If the atmosphere would be warmer with only N2 and O2, then doesn't that mean that GHGs cool the atmosphere (regardless of the temperature of the solid or water surface)? And if GHGs cool the atmosphere, then adding CO2 should cool the atmosphere one or two degrees in 100 years.

A decade even ? Or more ? I have found snowfall in lower-snowfall areas like near London and in Philadelphia as well as USA farther south to be very irregular, maddeningly random, with little correlation to global temperature on a time scale of a decade or less. - Don Klipstein (don(a)misty.com)

I would like to add that according to HadCRUT-3, October 1998 was the world's 6th warmest October on record. http://www.cru.uea.ac.uk/cru/data/temperature/hadcrut3gl.txt Same story according to HadCRUT-3v, good enough for The Register to use to attack NASA's GISS (and the scientist Hansen there) in their "A Tale of Two Thermometers" article. http://www.cru.uea.ac.uk/cru/data/temperature/hadcrut3vgl.txt - Don Klipstein (don(a)misty.com)

It's religion, not science any more. Hansen/GISS is now saying 5th warmest. A source used by The Register to attack Hansen/GISS says 6th warmest since 1850.
