I believe in climate change, it’s been happening since the beginning. I also believe in clean air and water. What I don’t think is settled is how much effect man has on the climate.
We are currently more than six years into Solar Cycle 24, and today the sun is virtually spotless. Solar cycle 24 began after an unusually deep solar minimum that lasted from 2007 to 2009, which included more spotless days on the sun compared to any minimum in almost a century.
If history is a guide, it is safe to say that weak solar activity for a prolonged period of time can have a negative impact on global temperatures.
There have been two notable historical periods with decades-long episodes of low solar activity. The first period is known as the Maunder Minimum, and it lasted from around 1645 to 1715. The second one is referred to as the Dalton Minimum, and it lasted from about 1790 to 1830.
Both of these historical periods coincided with below-normal global temperatures in an era now referred to by many as the “Little Ice Age.” Not saying it will happen, but it is very possible that cooler temperatures are coming.
