So here we have the scientists at work studying a very old asteriod and darn
it all they have a theory that it might have set off the melting of a great
deal of ice. No humans in sight.

Note also that this article freely mentions that the eart has gone through
cooling and warmin periods from way back and also that water vapour is a
green house gas which is responsible for half the global heat retention.

Of course burning hydrogen, or fuel with it in result in water vapour. Even
fuel cells ecject water. So its a good thing that it rains now and again to
get some of that vapour back to earth and out of the atmosphere.

A perfectly logical theory Gordon. There is evidence that large asteroids have the capability of making major alterations to the planet.

Again perfectly good science!
