That is cyclic and averages out on a decadal scale. There might be long term changes in solar magnetic activity on scales of thousands or millions of years that we can't do much about. In a few billion years Earth will be toast (but not because of sunspots).
The total amount of heat trapping gases present because of human activity has been increasing for centuries. We can "fix" that.
