I'm a little late to get into the initial part here, but if you are really interested in planet cooling, which I contend is a terrible thing to wish for, you can travel to
Space weather.com, and then go
check out the sunspots if you will note, there aren't any. and if you check the address window, it will show you that I am not cheating on the picture.
We should have been out of Sunspot Cycle 23 over one year ago, if you use the 11.2 year cycle average, but obviously we are not. This acquescing of Sunspots has been going on since 2005, and if the 4-7 year lag time holds accurate, you will all be getting what you wish: a cooler planet.
If we use the last two 178.7 year solar cycles, and extrapolate into the future, based upon data, here is what the cycles will look like, when matched together. Note that the current double cycle we are still in*(check the 2000-2020 date on the chart), are much lower than normal. In fact the next one, Sunspot Cycle 24, will be almost nonexistant. THis will result in a much cooler planet.
Sooo, if you are wishing for a cooler planet, your wish is about to come true, and Algore will be eating his words, OR most likely coming up with some Fantastic Excuse in the true Elmer Gantry Style.
*I use the term "double cycle" because ever cycle of solar sunspot activity results in a reverse of solar polarity. So, for every two sunspot cycles, you will see a return to the original polarity, where it starts over again.
