Again, though the water vapor emitted from cooling towers can and does create impressive cloud formations under the right conditions, this is a very different issue than being the primary mechanisms of Earth's
atmospheric water vapor generation for fueling storms which is what some are falsely claiming.
What it does show is a major role for
atmospheric water vapor, to which there is a significant direct human contribution from both the combustion of hydrocarbon fuels and the cooling needed by steam
generation of power, but one that is totally disregarded by Trenberth and the IPCC.
