Again, a simpletonistic linking of a single cause and and single effect, denying the extreme complexity of climate change.
Climate Change is a complex process, atmospheric warming is a very well understood result of a combination of factors.
The main driver/accelerator of atmospheric warming is CO2 (and Methane is playing a smaller role but it's weight as a contributor is increasing, due to Global warming).
Watervapor is another gas that contributes to a warming atmosphere, but its volume is limited to what the atmosphere can hold before it rains out again. However, since CO2 traps the heat, the atmosphere warms and expands, and the atmosphere can hold more water-vapor before it rains out. So,
CO2 also causes additional indirect warming due to allowing more water-vapor to build up.
All this can be found in the scientific literature, and more (like reflectance of sunlight by clouds and snow/ice surfaces, and absorption by ice-free ocean surfaces and landmass).
So we're back to square one, one needs to read information coming from reliable sources (peer-reviewed scientific literature), and not rely on the blogosphere.

P.S. Here's a magazine article (not a scientific peer-reviewed report) that pretty much explains in simpleton words what science tells us:
