Naturally, this 'confirms' global warming. Forget that the 1970's were freezing.
My take on this is that we had a huge El Nino, much bigger than 1997. It was the accumulation of several 'missed' opportunities, and eventually had to come in charging. We should see a return to the level 'hiatus', or even a dip below that. Right now, we are still warm because our weather is still coming straight from the West. That should change soon.
I would wait until Canadian oil and gas hit rock bottom with the huge US import tax of 25% about to hit it. The US is forced to do this, since it is the only way the trumpeests can raise money. Then I would invest, since we can expect the really big OK earthquakes in a year. And the freezing cold will really spike the demand.
ps. interesting that we may now be in an age of physics with the trumposity.
