In a way it's a good thing that this global warming thing is as big as it is. Remember that 'Necessity is the Mother of Invention' and with pressure from numpties in power, the gutter press and oil prices rising, one would hope that more breakthroughs for cheaper, alternative fuels will come about making air travel cheaper than it is now. Afterall, the world is money driven and while people say they care about the environment, AGW lie or not, they will always care more about their pocket.
