The real problem with jet travel is the stratosphere. There is no mixing between the stratosphere and the troposphere so there is no natural means for the CO2 to be removed from there. There is also the problem with contrails. These man-made high clouds act as a blanket and trap heat. In fact, just after 911 when air travel was banned there was a noticeable clearing of the skies and a corresponding drop in overall temp. in the US. It all points to a need to curtail travel and shipping over all.
