a new negative feedback

I have not hitherto heard of the possibility either by the proponents of
the "greenhouse warming" theory (e.g. IPCC) or by its critics (e.g. Dr. Idso
and Dr. Balling) that warmer winters in the major landmasses of the
Northern Hemisphere would result in decreased burning of fuels for heating
and therefore decreased atmospheric carbon dioxide, thus mitigating the
prior effect of increased carbon dioxide. Another possibility I have
heard on occasion, but which is not mentioned often in the scientific
community, is that according to the Milankovitch orbital mechanisms, the
next ice age should begin sometime between now and the year 4000. If ice
ages are indeed dictated by the orbital mechanisms, that would indeed be
a major negative feedback to "greenhouse warming".
GREENHOUSE GASES FELL 1.2% IN '01, REPORT SAYS
Washington--U.S. emissions of carbon dioxide and other greenhouse gases
decreased 1.2 percent last year, the largest annual decline in more than a
decade, according to a government report.
Experts said the decline had nothing to do with government policy changes
but instead was the result of an economic slowdown and an unusually warm
winter that sharply reduced demand for fossil fuels. Many scientists blame
the burning of such fuels for the Earth's warming.
"This is just one year's worth of data, and our projections don't indicate
the beginning of a new trend," said John Cogan, a spokesman for the Energy
