Thanks TargeT and Babs.
Clif High has an interesting take on the sun. iirc, he says that we're now entering a different area of space which is affecting the sun and the planets...that the sun is actually getting cooler (?) and we can expect an ice age even though people have the sensation that the sun is hotter on their skin. Hope I haven't messed that up!
Anyway, Clif's ideas tend to go against traditional ideas, so I take it with a grain of salt.
