This may seem revolutionary given all the emphasis put on CO2 as the so-called “climate control knob.” But we have a classic case of direct linkage to water vapor occurring, with high-latitude warming and the cold seasons revealing this most vividly. More water vapor means more clouds. In fact, the cooler it is, the easier it is to create clouds, as condensation processes are faster. So increased water vapor is likely to have its biggest effect on temperatures at the coldest time of the year.
CO2 cannot be causing what you’ll see below.
For instance, maximum temperatures for the nation during the front five days of the month were 2.34°F below average.
Minimum temperatures were 2.77°Fabove average.
For the front five days of December, this is a record spread! Now look at the water vapor so far:
The nation is…
