Look out the window right now. Can you see that smeary haze where there should
be blue sky? Apart from looking vile, for all that ice from the vapour trails
you can see theres just as much CO2 released that you can't see. Not to mention
all the other pollutants being shoved into the stratosphere.

Wrong on two counts. The ice reflects the sun and cools the earth, and
the jet engines draw in and burn methane, which is a much more powerful
greenhouse gas than CO2.
