Just to point out one obvious problem: the article you quote claims a huge increase in sunspot activity - 1825%. But the variation in solar luminosity hasn't been more than 0.1%.
So what's he supposing is the mechanism for heating? Molecules of mercury that are secretly fantasizing about sunspots, getting excited, and jumping up & down?
With respect to temperature trends: apply a 5-year smoothing filter (typical for climate considerations) and look at the trends over the last 100 years. They're pretty clearly upwards.
