"Over the past 20 years, however, the number of sunspots has remained roughly constant, yet the average temperature of the Earth has continued to increase.
This is put down to a human-produced greenhouse effect caused by the combustion of fossil fuels."
Now that was a leap!. I could also draw the conclusion that there is a lag in the relationship between the sunspot activity and earth warming. If so then we are headed into earth cooling as the sunspot activity slows down.
If the sun heats up just a little bit, it won't matter how many SUVs we don't drive.
