Scott Mackinney criticizes me in a comment on my blog about the damage I am causing to the environment with all of my air travel. I actually have been feeling a bit guilty about that and have been wondering where aviation is going to go from here.
On the one hand, in some areas, air travel is becoming cheaper and there are even people talking about small, low-cost private planes becoming more common.
A Feb 2000 GAO report warns that the damage to the environment from the emissions from aviation is particularly high because it is emitted into the upper atmosphere and that increased damage due to increases in travel can not be offset by technological advances. A report by the Intergovernmental Panel on Climate Change (IPCC), a group of experts affiliated with the UN warned that the share of global warming caused by air traffic could increase from 3.5% in 1992 to 17% in 2050.
We clearly have a problem here. In an IHT article that I can not seem to find a link to, I read that one of the possibilities was to fly lower where there would be more turbulence, but less damage. I've also heard about the idea of levying high taxes for air travel. In any event, the air travel utopia story seems a bit flawed and if we would get up off our asses and really do something about global warming (which we must) one of the first hit probably should be our global aviation habits.
I WAS going to write about this before, but hadn't been able to gather enough sources. (Honest! ;-) ) I still don't think I have enough information to have an educated opinion. Any pointers to more resources would be greatly appreciated.
