Some of the contributions a SO2 reflects heat as well as the
contrails. The engines burn some atmospheric Methane, but nitrous oxides
react with it as well, so there's another reduction in greenhouse
effect.

What a load of cock. SO2 soon reacts with water and comes out of the
atmosphere of its own accord and Methane reacts with O2 eventually anyway
plus most of it is near ground level, not at 30,0000 feet.

As for contrail reflections, they reflect heat out into space but also
back down towards the earth which doesn't help at night.

But nevertheless, add up all the contributions, even if some are short
term, and I've told you the answer.

So once everything everything out you're left with the 500 million
tons of CO2 that aircraft pump out each year.

That's about the same as emissions from petroleum and natural gas in the
UK alone.
