1. Mean Global Temperature
(a notoriously vague statistic, subject to
a lot of discussion) has increased by one half of one degree Kelvin
from where it was about 1900.2. Atmospheric levels of Carbon Dioxide have risen over the past two
centuries.3. Carbon dioxide is a "greenhouse gas"
(a minor one, compared to
water vapor and methane from vegetable and animal sources) whose
increase is likely to warm the earth.
When I say minor, I mean
that DOUBLING the CO2 content of the atmosphere would raise Mean
Global Temperature by about ONE degree. Someone who focuses on
this greenhouse gas has never mastered basic statistical logic:
always focus on the two or three LARGEST contributors to any
expense, problem, or situation you face: whatever your percentage
of effect, it will be larger than if you focused on the smaller
ones. Anyone who has studied power laws
to this conclusion quickly. As noted before, climatologists are not good at statistics
-- and that fact should make those models of
theirs subject to more review than they are getting.
What is in bold above is perfectly true, and is the consensus. Richard
S. Lindzen, Professor of Meteorology at MIT, supplied some of the
But these facts do not imply global warming. Two centuries ago
(before the increase in carbon dioxide noted above), much of the
Northern Hemisphere was emerging from the little ice age. A thousand
years ago, it was the Midaeval Warm Period, with temperatures higher
than now. Climate CHANGES all the time.
My own suggestion: the increase in carbon dioxide is Gaia's attempt to avoid another ice age, which, as pointed out before, we are due for.
UPDATE: Common sense breaks out in the Senate of the United States on Global Warming.
Three cheers for Senator Inhofe! For those who need further scientific proof, check out this page
FURTHER UPDATE: Early snow this year. How warm can you get?
LAST LAUGH: Evidently I could be prosecuted under newfangled statutes for "climate change denial". If so, I may fail to defend by laughing instead of speaking.
