I'm shocked that these articles don't even mention that there's also a natural cycle that could explain our warming and cooling over the decades: The Sun goes through a sunspot cycle every 22 years. When it's at a maximum in terms of the number of sunspots, which are those dark little spots you would see on images of our star, it's pumping out more heat and energy. We're in a sunspot minimum right now according to astronomers. There are way too many factors involved to answer about global warming, but why are we not paying more attention to the fluctuations of the only object in our solar system that provides the source for all of the energy that drives our weather?
