The graph is from 1991. Some newer or more detailed papers are here:

Most interesting are the data on the following page, which extends
observations to the year 2000:

While solar activity has dropped in the last decade, temperatures have
continued to rise, which doesn't fit that theory.
Back to the drawing board for the sunspot theories, I guess.
