re: The actual numbers, like anybody cares.

"Firstly, there is the greenhouse effect, and then there is global warming. The greenhouse effect is caused by certain gases (and clouds) absorbing and re-emitting the infrared radiating from Earth's surface. It currently keeps our planet 20°C to 30°C warmer than it would be otherwise. Global warming is the rise in temperatures caused by an increase in the levels of greenhouse gases due to human activity."

Love it.
So, if we want to discuss water vapor in regards to global warming it can only refer to the increase in water vapor caused by human activity.
And suppose since the the term "global warming" is being morphed to the term "climate change" then this same *rule* also applies?
