". . . global warming due to increased solar output. . . ."

This is simply inaccurate astronomy. As stated above, the sun goes through a regular 11-year cycle. Sunspot activity is on the increase right now, but this is NOT solar warming. Sunspot activity (periodic reshuffling of the sun's magnetic fields) will reach it's peak in 2112, then it will ease off until it happens again in another eleven years.

This has been going on for billions of years, and other than an increase in auroral activities ("Northern Lights") when sunspot activity reaches its peak, and some radio interference, the average person doesn't even notice it. Nor does it reflect itself in the earth's global temperature.

Simply business as usual. If we want to learn the causes of global warming, we need to look much closer to home. Like in the mirror, perhaps.
