Global warming by microwaves and not CO2

Microwaves can cause polar molecules to rotate. When they rotate they can lose their ‘microwaved’ energy by rotational based collisions, dissipating the energy in the form of heat in the process. That’s how a microwave oven works. Or so the theory goes.

Water is particularly sensitive to the microwaves, particularly the wavelengths employed in ovens.

Here then is a spur-of-the-moment thought.

Cellular communication (‘mobile phone’) networks need to be cellular due to signal drop off over relatively short distances. I speculate this is due to water and polar pollutants absorbing the microwaves. These molecular/particulate absorbers will therefore convert that EM radiation into heat radiation.

So IF what I say above is true, and 120 -> 380 ppb CO2 was such a big deal in terms of global warming, why then are are microwaves not demonized, especially given their proliferation over the last decade? Is it simply because nobody has (yet) thought of a way to milk money from people be cracking down on mobile phone use? so the chance they may contribute to global warming doesn’t matter?

Note : I don’t know the frequency that cellular networks broadcast on, the intensity of signal transmission or what the absorbtivity is at the wavelengths used.
