A few days ago I dug up some of the old global temperature files from a simple personal study I ran in 1987 and added data from 1988 to 2013. Even way back then in 1987 (and long before (1)), it was obvious that people were doing something to change the climate. That’s not surprising considering that we live in a thin haze much like a balloon’s skin, the chemistry of which we are changing with highly inefficient combustion engines, and into which we leak and dump gaseous waste.
Below, you’ll see a scatter chart of annual average temperatures in Buenos Aires from 1856 to 2016. Argentina has really good historical data.
Two things are clear to me. The first is that temperatures are rising. Temperatures are up over 2 degrees C since the mid 19th century. The second is that there is less variation from year to year starting in the 1940s or so. I don’t know what this means, but wonder if it has something to do with adding energy to a medium that really does not want to accept it. A form of thermal compressibility factor? Will we reach a point where something “snaps”? Or, maybe the instruments are better from the 1940s onward. Don’t know.
I have not included a lot of other information I collected in 1987. That included sunspot and UV radiation data that showed absolutely no correlation to temperature variations in Buenos Aires or anywhere else I looked. The sun is not causing the climate changes we are seeing now.
