Climate hoaxsters: Hey, we just remembered that CO2 has caused the air to become "super-saturated with water"! (By the way, if we start talking about drought ten minutes from now, please forget that whole "super-saturated air" thing)

Opinion: Record snow in a warming world? The science is clear — The Daily Climate [Hoax]
"Climate change contrarians and deniers love to dishonestly cherry-pick individual events to argue that they are somehow inconsistent with global warming, when they are not," said Michael Mann, director of the Earth System Science Center at Pennsylvania State University. "As long as it's cold enough to snow – which it will be in the winter – you potentially will get greater snowfalls."

The reality is that such snowstorms often don't occur despite global warming, but because of it. "It's basic physics, and it's irrefutable," Mann said.

The science behind this is clear: Warmer temperatures cause more water to evaporate into the atmosphere, and warmer air holds more water than cooler air. The air's "water-holding capacity," in fact, rises about 7 percent with each Celsius degree of warming. This results in air that becomes super-saturated with water, often bringing drenching rainfall followed by flooding or – if it is cold enough – heavy and intense snowfall.
Mann agrees that we are more likely to experience horrible snowstorms when the temperatures hover in the low 30s or high 20s Fahrenheit, rather than in the teens or colder.  [Hey Michael: How many "horrible" snowstorms will we get when temperatures are above the low 30s?]
