NASA Picture of the Day.

I have added a link on the sidebar for those of you who would like to check this out daily. Just below the Amazon link in the "More About Me" section.

M. Simon,

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.
