Whirls,
I wasnt targeting you - I dont know anything about your lifestyle, what you fly, or why - thats why I specifically targetted business jet owners, and huge economies which exempt themselves from the Kyoto treaty.
I never suggested that my flying was OK, and nobody else's was - the implication was that some sorts of flying (eg to save life & limb) is easier to reconcile with the negative effects than others (eg jetting a single pasenger to the Bahamas).
Nobody can claim to know for sure what causes climate change (although some contributors seem dead certain) - but surely we ought to keep an open mind to the possibility that it may be because of us, and it would be a big shame if we sat back and did nothing to stop it.
I'll go now.
