But in fact, human behaviour does not seem to be changing water vapour concentrations in the atmosphere, while as many many scientists have observed, rising concentrations of CO2 (which seem to be linked to rising levels of development, and energy production and use) are proportional to temperature increases.
Water is a much more complicated greenhouse gas because it goes into the atmosphere easily, but it also comes out easily. CO2, on the other hand does not leave the atmosphere easily, and it is having a measurable effect on our climate.
