Blaming we puny individuals on the surface of the Earth for global warming is nonsense.

Any gases we make - from cars, factories, forest fires and so on are dispersed at ground level by wind, rain and the greenery around us, even in towns.

The odd volcanic eruption may affect the upper atmosphere but the real culprits are jet engines, millions of them.

They are only on the ground for a short while. Mostly, they fly, three or four miles high, spewing out greenhouse gases where there is no wind, rain or greenery.

They are the real cause of global warming. When our skies began to fill with jet engines, the Earth's temperature began to climb.

And we can't do anything about it - rationing flying time or banning night flying would only slow down the process, if every country could somehow be made to agree to it. Nothing can solve the problem.

It would take a disaster of the magnitude of the one that killed off the dinosaurs to do it.

Instead, humanity will have to adapt to changing conditions, as it has done since time began.
