Well, folks were complaining that my graph of the CET compared to the centennial solar minima was just one location, England. So here are the five European temperature records which start before 1815. Now, if the theory of the solar/temperature connection is correct, the temperatures should start trending downward when the solar minima start, and they shouldn’t start warming back up until the sunspots get numerous again after the end of the minima. Here are the records so you can see if they agree with the theory:
Color me unimpressed. As you can see, there is no obvious sign that the solar minima have caused any change in the temperature. Some go up, some go down, some go nowhere.
Yes, I understand that this is not a global dataset … but then, they generally don’t go back far enough to catch the Dalton Minimum, which starts in 1798. If you have a dataset you’d like me to graph up, put a LINK to the dataset in the comments.
I leave further discussion to the wisdom of the readers.
Best regards to all, another rainy night here, California needs rain so it’s all good,
