Global warming: is there enough evidence for a war?

Brian Hanson, in supporting the case for anthropogenic global warming (AGW), refers to 'impartial' scientific research (Letters last week). And there's the rub.

Because virtually all those connected with the IPCC, and many other climatologists, are directly or indirectly in the pay of governments committed to AGW theory, and interested only in research results that support it. Impartial scientific climate research under these circumstances is about as rare as impartial intelligence assessments were in the case of the Iraqi Weapons of Mass Destruction. And any governmental employee who has studied the contrasting career paths of Sir John Scarlett and the late David Kelly will surely know on which side his or her bread is buttered.

It is therefore vital to search out such truly independent climate scientists as may exist, and ensure their research results are publicised and their views heard.

While conservation of fossil fuel resources is surely important, whatever position is held, some other policies currently propounded may actually make matters worse rather than better if the scientific basis is uncertain.

Even AGW enthusiasts frequently include "could" and similar weasel words in their forecasts – witness the three uses of "could" in the short paragraph setting out Rajendra Pachauri's views in your recent editorial (Comment, 24 July).
