I looked at the article and no where did I see the length of "recorded history" defined. I saw one mention of "a century ago". I don't think a mere 100 years of data in the time line of earth is enough to make predictions about anything.
But then again, I'm not a scientist.....
The weather station in our county did not exist before 1928.
It was established for the airmail pilots. Those guys that flew biplanes at little more than tree top level following rotating beacons at night.
When I was a kid, there were barn roofs painted with the names of the nearest town and an arrow pointing in that direction to help pilots flying during daylight.
So I am supposed to believe that thermometers in use before that station was established were accurate within one degree?
Look at who wrote this crap article. When I saw that he spelled program programme, I knew what was coming.
Written by the guys that have already been exposed for doctoring the numbers for their own reasons.
I might add that to compare weather over a long period of time, the same thermometer placed in exactly the same spot with no changes in the surrounding areas would be required.
Temps recorded by George Washington and your grandfather are useless.
Just watch the temps on your car as you travel up or down small hills, or your side mirrors at night fog up with condensate and 2 miles later clear up as the temp rises.
Think about it and you can see how the con men give us bad information and do it legally.
Con men striving for government grants.
And don’t forget that the Russians did it.
