Then we switched to La Nina. The US eventually followed into cold this fall/winter. Now the entire globe is colder then normal. The last La Nina resulted in up to a negative 5 % anomaly in water vapor density. So the atmospheric density decreased and so did its heat capacity. Right now the question is when will this winter end ? We have another major blast of Arctic air coming this Sunday night and we were supposed to warm up before then.
We restocked on light long underwear. Have a feeling it's going to be an especially cold winter.
I remember a winter or two as a kid so cold that it froze mud puddles on the waterfronts of the central California coast, just south of Big Sur. Doesn't happen very often. At least not in our piddling lifespans!
