Report on Climate Change Prediction

A seminar held earlier this year to discuss the validity of current scientific strategies, particularly computer modeling, which are being used to establish and evaluate the link between global warming and human activity has been detailed a report called Climate change prediction: A robust or flawed process? and published by the Institute of Physics.

Richard Lindzen, Professor of Meteorology at the Massachusetts Institute of Technology spoke at the seminar and explained the limitations of climate models. He outlined why attempts to attribute global temperature rise to an increase in CO2 emissions were flawed.

Prof. Lindzen noted that, according to the latest IPCC Summary for Policymakers of the Scientific Assessment, we are already 86% of the way to the radiative greenhouse forcing associated with the doubling of CO2 and we have seen a change only of between 0.6 and 0.8°C in the past 100 years, which would be too small even if all of it were due to anthropogenic greenhouse gases. (emphasis added)

Lindzen pointed out that the records of the Hadley Centre, show that there has been no warming trend in global average temperature for the past ten years.

"Attributing global warming to the rise in greenhouse gases has been reduced to an issue of religious faith modulated by policy relevance. Unfortunately, in my experience when politics enters the picture, science takes a back seat - even among scientists." Prof. Richard Lindzen
