Thanks, TB.
Good data, although I also find it hard to see how any human activity could substantially alter the amount of water at the earth's surface; the oceans are full of it. There are CO2 sinks, too, in solution in sea water, carbonates in marine organisms, plant tissue, etc. But if CO2 levels in the atmosphere are rising, doesn't this suggest these sinks may be either failing to function, or are becoming saturated? Rising temperatures may add to the amount of evaporated water as well, but clearly this has not led to runaway greenhouse effects in the past, because the earth is still pretty habitable, and has been continuously supporting life for billions of years.
