Someone started another "warming" thread in the blind alley known as, "Friendly Politics." I posted this there:
So few seem to understand what more heat in the atmosphere means. The spot checking presented as proof that warming isn't happening, as the averages go up, is actually more proof of the collected thermal energy than a refutation of heating.
More heat into the atmosphere means more evaporation of surface waters. The warmer the atmosphere, the greater amount of water it can hold. When there is more water in the atmosphere, there is more potential energy that will be shown up as motion. The atmosphere cools, locally, via the motion of the centripetal vortex, a.k.a., cyclonic motions. These motions are what we call, "weather." More snow, rain, cyclonic wind, is the fallout of the greater amounts of evaporation in a generally warmer, more saturated, air mass. It is the payoff for the retention of heat.
These forces cause extreme cellular cooling and unpredictable and extreme variations of the jet stream (speed and path), causing increased local cloud coverings, precipitation, and in many cases, locally colder temperatures. Watch the averages and understand that the high and low extremes are what the atmospheric capture of solar energy predict. Every vortex that cools the air is an engine, a motor, if you will. We have hot-rodded our atmosphere, and it's hitting on all cylinders.
We can enjoy a mild winter or spring, but we certainly can't count of having many of them. I'd say, "batten down the hatches." We're in for large helpings of the unexpected.
