Although solar activity is associated with sunspots, there is no associated increase in solar output. Historically sunspot activity waxed and waned on an 11 year cycle, which maps to no identifiable earthly weather pattern of matching period.
Yes the photosphere is 100 times the diamater of the earth and large sunspots are larger than the Earth.

They interfere with all types of RF (radio / TV) transmission / reception.
Greenhouse gases are helpful because they keep the earth warm enough for life. Too much greenhouse gases warm the earth up too much.

Nothing Much.
There are no sunspots on the Earth; SUNspots are spots ON THE SUN. They are "dark" (well, SLIGHTLY less bright) spots on the Sun that happen to be correlated with solar flares and coronal mass ejections. The number of spots on the Sun varies up and down on a cycle that is approximately 11 years long. We're not sure why. You can see today's Sunspot Number online at spaceweather.com.
