Mickey Mann Can See Climate Change From His Window – Part II
By Paul Homewood
According to Mickey Mann, “We can see climate change, the impacts of climate change, now, playing out in real time, on our television screens, in the 24-hour news cycle”.
So, I wonder what he can see when he looks out of his window at Penn State?
The longest running USHCN station in Pennsylvania is Uniontown, which has largely complete records dating back to 1872.
First, let’s see what it tells us about temperatures.
The above chart is based on USHCN adjusted temperatures, not raw, but still show that temperatures in recent years are little different to the period from the 1930s to 50s.
The whisker plot below of monthly mean temperatures shows that the hottest months are not getting hotter. Also, while the extreme cold months common in the 1970s and 80s are not so prevalent, we again see little change from earlier decades as far as winter is concerned.
Of course, we are often assured that, while averages may change little, it is the extremes that are getting much worse. Unfortunately, the facts don’t agree!
The chart below shows a whisker plot of daily maximum temperatures. Clearly, extremely hot days have become much less common in the last decade or two. Again, we see that the coldest days occurred in the 1980s and 90s.
Ah, but what about rainfall? Surely we are getting more floods and droughts now?
Aren’t those darned facts inconvenient?
Not much change in annual rainfall, is there Mikey?
Monthly rainfall extremes? Oh dear!
Or daily extremes?
Maybe it’s snowfall then. John Holdren assures us that winters are snowier because of global warming.
Afraid not, John!
NOTE – There is some missing data between 1971 and 1988.
I don’t know what it is that Mickey is seeing, but it certainly ain’t climate change. Perhaps he has been at the Jamaican Woodbines!
