Water Vapor Rules the Greenhouse System

Just how much of the "Greenhouse Effect" is caused by human activity?

It is about 0.28%, if water vapor is taken into account-- about 5.53%, if not.

This point is so crucial to the debate over global warming that how water vapor is or isn't factored into an analysis of Earth's greenhouse gases makes the difference between describing a significant human contribution to the greenhouse effect, or a negligible one.

Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many "facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.

I've replied to the Water Vapour talking point so often now, that I will just suggest you look around for my comments on it.

Thanks though, apparently this is the latest not unimportant, but clearly misguided attempt to debunk what is year by year becoming increasingly clear science.

Although at least this isn't such blantant sophistry like the stupid "but its getting warmer on Mars" reply.

And, thanks for not telling me, "it was darn cold where I was this winter".
