A funny thing happened after 9/11. All commercial flights over the US
were halted for a few days. During that period:
- An amateur researcher in the middle of the country, who had been
carefully recording surface temperatures for many years found a
significant increase. Once air travel was resumed, it went back down to
the prior trend.
- There's an English born Jew who emigrated to Israel decades ago. He
has been researching the solar energy falling on the Earth's surfaces.
His concern is that it has decreased, which has reduced the total energy
available for plants to grow, and thus the ability to produce food. One
of the grad students he has working on his project is also in the US and
noted a significant increase in solar energy intensity during the no-fly
period.
As I understand it, this is a result of the ice crystals created as jets
fly at altitude. I've both heard that it's a direct result of the
crystals creating a reflective layer that bounces sunlight back out of
the atmosphere and that the same effect is a result of the ice bonding
to tiny particles.
In any case, airline travel appears to be one of those troublesome real
world things that both cause a problem, the greenhouse effect from their
output of CO2, and create an opposite effect at the same time.
I have no idea what the balance is; I doubt anyone really does, but
Chris might allow himself the occasional bit of air travel without too
much guilt.
