I was at the World Economic Forum in Davos in January and was aghast at the global warming hysteria sweeping the place, with airlines being demonised for their alleged 1.4 per cent contribution to global emissions. Airlines are at the heart of the travel and tourism nexus, linking engine and airframe manufacturers, hotels, car hire, tour operators, travel agencies, connected businesses, and the communities which they serve. If the Green extremists, and their cohorts in governments and the media have their way, hundreds of thousands of jobs in the travel and tourism industry will be lost in the years ahead, against a very dodgy maybe, unsupported by any conclusive evidence, and with a tide of evidence now sweeping in the opposite direction.
