One of the favorite pseudoscientific attacks on global warming (and climate change in general) doesn't even address the evidence that greenhouse gases are driving the rise in average surface temperature. Instead, it suggests that the warming is coming from increased solar output or some other imaginary energy source outside our atmosphere.

Well, those troublemakers at NASA decided to compare the solar output (at a relative low from 2005 to 2010) to the heat retained by the Earth. Guess what? The retained heat rose while the energy of the Sun fell.

Game-set-match? Maybe not, but let's see the naysayers dispute a nice empirical analysis like this one.
