This article has very very little to do with climate change and a lot more to do with local climate, or weather, as it is talking about the temperature of North America, which is not the global climate.

As for claiming that understanding of a variable at one scale requires the prediction of other variables at smaller scales in the same system, consider signal to noise.

What this article is saying is that the US is very hot, early in the year. Somewhere else might be very cold right now. Or it might not, this article does not say either way.
