Interesting Thought

Aside from clouds, water vapor accounts for as much as two-thirds of the earth's greenhouse-gas effect. Water vapor traps heat from escaping the atmosphere -- but clouds have the opposite effect (called "albedo") by reflecting the sun's energy back into space. And snow on the ground from the IPCC's predicted precipitation in high latitudes would have the same cooling effect as clouds.

What the new research suggests is that changes in water vapor may well trump the ef fect of carbon dioxide (only a fraction of which is man-made) and methane (which has mysteriously slowed since about 1990).

This raises an intriguing question: Since the Environmental Protection Agency declared that it has the authority to regulation carbon emissions because of their presumed effect on the global climate, why hasn't the EPA also attempted to regulate mist and fog?

OwlGore strikes (out) again.
Good question. Still no good answers from Hopey's Dopes except the burning need to control.
