While they can argue all the want about how radiation trumps convection in heat transport, we can concentrate on physics. The big physics controlling our temps is the state of the ocean. Water transports and stores heat 4000 times greater than air by volume. So all our heat transport is water, not air.
If we didn't have oceans the whole planet would rigidly stratify, like Jupiter. Lucky for us, the Pacific Ocean holds all its heat for a number of years, and then has to burst out. That's called El Nino and this one was so huge that it squeezed out all our heat like a lemon.
Our Gulf Stream is generally not bothered by that cycle, and her you can see it in full force. Last year it broke up for a while.
The Pacific is now dead. It's hopeless quivering mass. Normally, the northern Pacific current supplies North America with cool moisture. The Gulf Streams hits us with hot and humid weather.
We would be quite happy if the Gulf air plume stayed over us forever. Then we would have Florida weather forever. But the northern air has to come down. Normally, the nice Pacific sends warm air into the Yukon and then it descends. But that's not going to happen for 10 years.
We've established a new, horrible pattern. The Gulf Stream air plume goes over Europe, over nasty Russia and then comes down on us. Very cold.
This is the latest moist air map. Our cold air whips around the North Pole and then comes down on us. If it can fight off the Gulf plume, then Texas stays warm and we freeze.
This is a wonderful time. For the last few big cycles we haven't had these maps. There's been no physics in climate studies. At least you can see it here, and nowhere else. :)
