Answer 2

The sun spots that are active in a 11 years cycle influences the earth's magnetism and as such, communications, satellites, and create beautiful northern lights when very active. Radio amateurs follow very closely those solar activites because those are what makes intercontinental radio communication easy or difficult.

But as far as I know, it doesn't change the climate at all.

Answer 3

Sunspots are correlated with changes in the sun's irradiance, that is, how much energy the sun is putting out.  It is not necessarily the sun spots that are causing this, it just may be a side effect--sort of like when you get sick you have a fever, but it is not the fever that is causing you to be sick.  Anyway, all things being equal (which they certainly are not at this point, because of greenhouse gases), more sunspots would mean a warmer Earth and fewer sunspots would mean a colder Earth.

Answer 4

I think sun spots make the earth warmer

Answer 5

I actually did a research project on this and it actually showed that sunspots cause tropical cyclones and earthquakes because when there's a lot of sunspots there's a lot of tropical cyclones. But I couldn't find an explanation for it, so that would mean I was just lucky and found a correlation. But the sunspots send out solar flares that get into the earth's ionosphere and it creates the Aurora (Northern and Southern Lights). And these solar flares cause pulses in the earth's magnetic field that trigger earthquakes. So they are known to cause seismic activity but as far as I know sunspots do not affect earth's climate.
