DEBUNKING THE GLOBAL WARMING ALARMISTS



By Terry McCrann

Does the heatwave sweeping -- and seemingly staying -- across Europe, signal that the dreaded global warming has intensified? .....

In the shimmering glare of Europe's summer one of our leading analysts of these issues, Alan Oxley, puts the topic under the analytical microscope. In his latest "Climate Change Backgrounder".

Oxley makes three key points:

The UN Intergovernment Panel on Climate Change (IPCC)-the Green equivalent of the Pope in its environmental infallibility -aserts that the 20th century was the warmest of the past 1000 years. But according to analysis cited by Tech Central Station, a US public policy website, the most comprehensive review of relevant scientific literature finds that many parts of the world were warmer in the 800-1200 period.

Climate change computer models predict warming in the troposphere (the lowest layer of the atmosphere). But satellite observations back to 1979 show little warming there despite much greater warming on the surface. Probable answer: It's due to natural variability andiorland use changes. Not the evil carbon dioxide.

The key point in the greenhouse argument is increased water vapor in the atmosphere as higher temperatures trigger evaporation. Problem: The evidence is that evaporation in the Northern hemisphere -- where all the wicked power-consuming economies are has actually fallen over the past 50 years. Oxley makes the crucial point that our capacity to predict global weather patterns is weaker than our capacity to predict economic trends. And consequences.

Despite the IPCC's "infallibility", the only safe conclusion is that global warming is not and will not be as dramatic as claimed. We have time to assess the issue calmly. And deal with it, if necessary. In time. But cutting global economic growth will be devastating.

The above is an excerpt from p. 73 of THE SUNDAY TELEGRAPH (Australia) of August 17, 2003
