Think of it this way: 117 years ago the primary means of recording temperature was for a human to visually read a thermometer or crude cyclinder-like recording device that was most likely located in someones back yard in a rural area, and then manually record the information in a log book, which was passed on from time to time to the people who care about this stuff.
“Hey Pa, please check the temperature on your next rip to the outhouse.”
“OK Ma. Looks like 37 degrees or is that 36 degrees? What the heck - yesterday I rounded up, today, I'll round down.”
Pa writes down 36 degrees in his log book, but the “6” looks like a “5” and so when Pa sends his log to the Meteorology Department at Podunk University, the temperature from Pa's outhouse is officially recorded as 35 degrees. Spread the human error to weather collection points across the Country if only because "we all make mistakes," and then compund those errors over the years until the perfection of supercomputers and weather satellites, and I woould be shocked if average tempretures didn't change consideribly in 117 years.
I found it very interesting that the article (even though we’re all going to die) never mentioned globull warming.
God’s jet stream was blamed!
And it's about damn time! The Left has been promising me global warming for 40 years - it was nice going through a New Jersey winter not buried in snow or freezing my ass off!
