Does Air Travel Cause Global Warming?

Suzuki, Gore and other climate change hypocrites never mention airplanes as possible contributors to climate change because they would never take the train or a bus to their many profitable talk destinations.

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.”

Any fossil fuel bruning contributes to global warming. Air travel due to it's volume and frequency is clearly a contributor. You'd have to looks at statistics to see if it's worse than power generation or land based transport.

You're missing my point. It's not just the carbon dioxide emitted by the planes, it's the artificial clouds they are generating in the stratosphere. If planes flew at 10,000 feet altitude it would only be the CO2 that they produce that adds to the problem. The cloud generation may be far worse.

If planes could use hydrogen (a non-fossil fuel) they would still produce artificial clouds at stratospheric heights where they are most effective at reflecting heat back down.

Oh yeah, and lots of folks like their annual or quarterly flights to Cuba or Cancun, so lets just trade carbon credits and shut up about them cloud thingys.

Personal cars pollute million times over airplanes. The distance with how many passengers they carry per trip makes it THE most fuel efficient. Exception is the shinkansen or ICE trains, but no such option for intercontinental travel

Humans cause global warming.
A life spent making mistakes is not only more memorable, but more useful than a life spent doing nothing.

Reality is much more complicated that the above simple statement. In fact, the opposite is often true. The distance travelled, the number of passengers in a plane or car, type of car, etc. contribute to the calculations.
“If you are driving alone in a vehicle that gets 40 mpg or less – somewhat close to Professor Sivak’s average car trip in the U.S. including commuting, shopping, etc. – flying may be more efficient,” Rutherford and Kwan note. “If you have one or more additional passengers, driving is typically more efficient unless you are in a large vehicle.” And if you are driving a hybrid with a bunch of passengers, they contend, you are “four to five times as efficient as a plane over a similar distance.” In that scenario, they say, you even beat taking a Greyhound.

Of course, driving with three or four passengers in a BEV would be far, far preferable.

What terrible sacrifices for the most privileged generation in the history of homo sapiens to make in order to give future generations a planet that is merely livable.

Addressing climate change will be complex. It will involve reducing or eliminating unsustainable activities, modifying activities that are damaging but otherwise desirable, and developing technologies to permit the continuation of activities that are damaging but necessary.
