El Nino/La Nina also effects US continental weather to a great detail.
I don't doubt that temperature variations happen, Charby. And the effect of the ocean in contributing to US weather is certainly well documented.
But the linked article claims heat spikes and plateaus, but never mentions drops. Despite the fear of globular cooling in the 70's following the "plateau" mentioned in the article in the late 60's and early 70's. And no mention of the fact that the data gathering substations used for the last 75-100 years have had concrete heat islands build up around them, interfering with proper controls in an experiment and contributing to increase in the temperature gathered at that site.
ETA: I'm of the opinion that the data for the last 100 years needs to be completely discarded. And if not, then it needs
a nice big asterisk next to it to indicate its suspect nature.
