I was listening in on radio talk show last night, and the guest said that there is scientific evidence supporting the fact that over the last ten years there has been no Sun spot activity on the Sun. We here on Earth have been experiencing global cooling for the past ten years. This has happened in the past. When we have no Sun spot activity, we do experience a global downturn in the Earths average temperature. When we have increased Sun spot activity, as we did during the 70's and 80's , we have an increase in the Earths temperature. This has all been scientifically proven. This is why we are now experiencing a period of global cooling.We have no Sun spot activity on the Sun.
