But they say radiation does not. How can UV increase if radiation does not ? UV is radiation. They contradict themselves because they do not want to admit their holy grail, radiation does not increase, is horribly wrong. This is not not picking. It demonstrates how NASA missunderstood the solar cycle for decades and now wants to cover up their own incompetence and stupidity.
Does the number of sunspots have any effect on the climate here on Earth?
Sunspots are slightly cooler areas on the surface of the Sun, due to the intense magnetic fields, so they radiate a little less energy than the surroundings. However, there are usually nearby areas associated with the sunspots that are a little hotter (called falculae), and they more than compensate. The result is that there is a little bit more radiation coming from the Sun when it has more sunspots, but the effect is so small that it has very little impact on the weather and climate on Earth.
