Does Air Travel Cause Global Warming?
Clouds (including condensation trails from aircraft) reflect heat radiated from the Earth back to the ground (also, water vapor is one of the most potent greenhouse gases), that is why clear sky nights are so much cooler than cloudy nights.
After the attacks on 9/11 planes were grounded in the USA for three days and the skies were unusually clear. Banning air travel may well get the biggest bang-for-your-buck, as far as slowing or reversing climate change, but don't expect the elite to jump on this bandwagon.
"In 2004, NASA scientist Patrick Minnis wrote that “increased cirrus coverage, attributable to air traffic, could account for nearly all of the warming observed over the United States for nearly 20 years starting in 1975.”
