Did Piers Morgan Study History At School?
By Paul Homewood
Last week Piers Morgan, (better known to UK readers as Piers Moron), staged a debate on his show between Bill Nye and Marc Morano.
Morgan introduced the discussion by saying
Our big story tonight, you are so hot, America. And I mean that literally. The temperature was a balmy 60 degrees this afternoon in New York just outside CNN’s studios. The average high temperature in December is normally 43. A warm front has flooded the lower 48 states with 482 daily high temperature records across the country on Monday alone. Quite extraordinary but is it evidence of manmade global warming?
But just how extraordinary was this temperature?
USHCN data for New York suggests that while it was unusual, it certainly was not unprecedented, as the graph below shows.
The hottest December day was in 1998, when the mercury reached 75F. In the record since 1876, there have actually been 171 December days prior to this year that recorded 60F or higher.
In other words, the likelihood is that New York will see such a temperature in December every year on average.
Many of these events took place in the first half of the 20thC. For instance, on 10th December 1946, the temperature in Central Park reached 70F.
Even back in 1881, the temperature reached 67F.
Meanwhile, December temperatures in New York State have been declining for the last 20 years.

Morgan ends by saying to Marc Morano
OK. Look, I respect that you have views. I don’t think they’re facts and there are many scientists who would take issue with you about the use of the word facts.
I don’t think Morgan would recognise a fact, even if it jumped up and hit him in the face!
