Evidence agriculture is one major source of human-caused global warming

I found an interesting citation in the Reader Comments of an article in
today's San Francisco Chronicle about declining revenues at ski resorts
and its supporting infrastructure. The ski resort article is he

and is fraught with errors due to shoddy reporting which is now
typical of the Chronicle for the past 10+ years.

The citation from the Reader Comments is to a report in the "Journal
of Climate" of the American Meteorological Society whose journals are
online here http://journals.ametsoc.org/.

The Reader Comment presented this info:

The PDF at the immediately above URL is 16 pages, 1.3MB.

The Abstract concludes with this sentence:

" A working hypothesis is that the relative positive trends in
" Valley minus Sierra minima (0.4°C decade^-1 for summer and fall)
" are related to the altered surface environment brought about by
" the growth of irrigated agriculture, essentially changing a
" high-albedo desert into a darker, moister, vegetated plain.

Similar reports exist detailing temperature rise in and around cities
due to increased use of concrete for buildings and roads (think of
Los Angeles, New York, etc.).

No, you see the amount of snow was supposed to greatly -increase- but
that was according to computer models that needed adjustment.

Now that they have new data they can tweak the models to give the
result that they want: Global Warming is causing the amount of
snowfall to remain unchanged.

So greenies should lead by example; stop eating (and hopefully, DIE).

Greenies have often been a prime source of natural fertilizer.
