Above is a National Oceanic and Atmospheric Administration (NOAA) weather forecast from September 19, forecasting our weather for October. It said that it was going to be warm, much warmer than normal out here in the western US.
In fact, as we all know, October has been cold, much colder than normal. I’ve spent much of my time plowing and slipping on that cold. I had to put a sign up in our driveway to be careful, as you might slip and fall if you listen to NOAA predictions. (We had an ice storm that preceded deep snowfall.) I don’t want to be sued by Amazon.com drivers.
The lesson: Weather forecasts are good for a few days. Beyond that, forget it. People who imagine they can forecast climate ten or even 100 years from now are clinically insane or politically corrupt. Or both.
