Document Summary

Climate is a long-term pattern, usually measured over a time span of 30 years. Climate is what you expect, weather is what you get.

Dark patches of high magnetic activity that are constantly changing. Solar winds come out of them, along with huge amounts of charged particles. They do impact climate, but it is unclear how.
