CONT

The oceans influence the climate response in two fundamentally important ways ... If for some reason the ocean does not respond to the greenhouse heating, the H2O feedback would be turned off since increased evaporation from the warmer ocean is the primary source for increasing atmospheric H2O.

OBS

In the chemical formulae, the number 2 is in subscript position.

OBS

Water Vapor. The most abundant greenhouse gas, it is the water present in the atmosphere in gaseous form. ... In addition to its role as a natural greenhouse gas, water vapor plays an important role in regulating the temperature of the planet because clouds form when excess water vapor in the atmosphere condenses to form ice and water droplets and precipitation.

OBS

Atmospheric water vapor above the tropopause is referred to as "stratospheric water vapor".
