TWW is getting so befuddled about all of the stuff coming out by scientists (including Jim Hansen who is one of the leaders of the AGW movement) questioning CO2 as the one and only evil substance in the world, that he is copying part of a blog here. This post is by Steven Goddard:
"Summer snow cover is affected by many factors, but probably the most important one is soot, as Dr. Hansen has stated.
The effects of soot in changing the climate are more than most scientists acknowledge, two US researchers say. In the Proceedings of the National Academy of Sciences, they say reducing atmospheric soot levels could help to slow global warming relatively simply. They believe soot is twice as potent as carbon dioxide, a main greenhouse gas, in raising surface air temperatures. … The researchers are Dr James Hansen and Larissa Nazarenko, both of the Goddard Institute for Space Studies, part of the US space agency Nasa, and Columbia University Earth Institute.

The global warming debate has until now focused almost entirely on carbon dioxide and other greenhouse gas emissions, but scientists at the University of California – Irvine, suggest that a lesser-known problem – dirty snow ** – could explain the Arctic warming attributed to greenhouse gases….The effect is more conspicuous in Arctic areas, where Zender believes that more than 90 percent of the warming could be attributed to dirty snow.http://www.scienceagogo.com/news/20070506202633data_trunc_sys.shtml
In summary, winter snowfall is increasing and currently at record levels, and summer snow extent is not changing much. Earlier changes in summer snow extent were likely due primarily to soot – not CO2."

** TWW is still searching for information on the damage to the planet being done by yellow snow
ps. This also shows why it is bad to plant pine trees in the north country. The pine trees do not relect light like snow does so they heat up the planet.

hfec dont know nothing about no stink 'n snow, but i think he read in the readers digest, and all of that stuff there is true you know, cattle produce more harmful gasses than our automobiles..i dont know about the old fords though some of them seem to smoke a lot. also while im getting so fill o soffic here, i believe some of our forests up nort der would also flunk an epa..upaa,upee whatever..test for excessive something or other. i say, let the grass grow, dry it in the garage and do whatever with it. my brain is getting tired. this is about all hfec think in one setting. stay well yours in jpeace hfec
