FACT: The National Academy of Sciences reported in 2001 that, "Because
of the large and still uncertain level of natural variability inherent
in the climate record and the uncertainties in the time histories of
the various forcing agents...a causal linkage between the buildup of
greenhouse gases in the atmosphere and the observed climate changes
during the 20th century cannot be unequivocally established." It also
noted that 20 years' worth of data is not long enough to estimate long-
term trends.

Out of date.

NAC report, 2006:

"The committee pointed out that surface temperature reconstructions for
periods before the Industrial Revolution -- when levels of atmospheric
greenhouse gases were much lower -- are only one of multiple lines of evidence
supporting the conclusion that current warming is occurring in response to
human activities, and they are not the primary evidence. "


FACT: Predictions of 6°C temperature rises over the next 100 years are
at the extreme end of the IPCC range (read the report).

Yeah, that's a fact. At least you got one right.

What you apparently don't know is that many scientists whose work was used by
the IPCC have said that the 4AR was too conservative.


FACT: Both James Hansen of NASA--the father of greenhouse theory

Wrong. Hansen is not "the father of greenhouse theory."

and Richard Lindzen of MIT--the most renowned climatologist in the world--

Renowned? Haw-haw-haw! You mean notorious. Lindzen is a whore.

FACT: No one has provided data that conclusively links human activity
to the temperature rise of 0.6 C over 100 years.


FACT: No one has proven a causal link between CO2 and global
temperatures. It may be a cause, but is more likely an effect.



Science doesn't prove things. Science develops theories that describe events
and processes in nature. The theory of anthropogenic climate change is now so
robust it is accepted by every major scientific organization in the world. Of
course, I realize you find Michael Crichton more credible.
