Global Warming Follies


No smoking hot spot

(Thanks to my bro John for tipping me off to this article.)

Writing for The Australian, David Evans, a former consultant to the Australian Greenhouse Office from 1999 to 2005, says that:

1. There is no greenhouse signature in the atmosphere;

2. There is no evidence that greenhouse gasses have caused global warming;

3. The globe hasn’t heated since 2001 and has recently cooled .6 degrees centigrade to 1980 levels; and,

4. Ice core samples of previous warmings show temperatures rising BEFORE carbon levels raising big questions about cause and effect. 

Then Mr. Evans raises some interesting points:

The last point was known and past dispute by 2003, yet Al Gore made his movie in 2005 and presented the ice cores as the sole reason for believing that carbon emissions cause global warming. In any other political context our cynical and experienced press corps would surely have called this dishonest and widely questioned the politician’s assertion.

[…]

So far that debate has just consisted of a simple sleight of hand: show evidence of global warming, and while the audience is stunned at the implications, simply assert that it is due to carbon emissions.

In the minds of the audience, the evidence that global warming has occurred becomes conflated with the alleged cause, and the audience hasn’t noticed that the cause was merely asserted, not proved.

So when will the press demand proof of the assertions made by the GW crowd? Don’t hold your breath.
