Stop scapegoating the sun - Solar irradiance alone fails to account for warming

It's reasonable to assume that changes in the sun's energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system.
Indeed, studies show that solar variability has played a role in past climate changes. For example, a decrease in solar activity is thought to have triggered the Little Ice Age between approximately 1650 and 1850, when Greenland was largely cut off by ice from 1410 to the 1720s and glaciers advanced in the Alps.
But several lines of evidence show that current global warming cannot be explained by changes in energy from the sun:
* Since 1750, the average amount of energy coming from the Sun either remained constant or increased slightly.
* If the warming were caused by a more active sun, then scientists would expect to see warmer temperatures in all layers of the atmosphere. Instead, they have observed a cooling in the upper atmosphere, and a warming at the surface and in the lower parts of the atmosphere. That's because greenhouse gasses are trapping heat in the lower atmosphere.
* Climate models that include solar irradiance changes can’t reproduce the observed temperature trend over the past century or more without including a rise in greenhouse gases.

Perhaps it is time to accept that there IS such a thing as the Greenhouse Effect... we've only known about this phenomenon since 1828. It's not a wacko theory that was just recently made up by the demonized IPCC. So, exactly why are we denying it? Most people who deny it act under the assumption that they know more than the global scientific community. That would be laughable if this wasn't such a serious topic. This is not a global conspiracy. This is science, and it is real, and scientists are much smarter than deniers on this subject - so cease the arrogance. Find some humility and accept that humans aren't exempt from consequence. Open your eyes to the reality of cause and effect...
CO2 = Greenhouse Gas -> Greenhouse Effect = Warming
If you pump CO2 into the atmosphere (*cause*), then you will experience warming (*effect*).

I wonder how Glenn beck responded to this?

Almibry:
Beck would use his chalkboard to show that global warming is a result of socialism/communism/Nazism/Stalinism/Marxism/Leninism and ACORN in the atmosphere. He might also suggest that global warming has a deep-seated hatred for white people. Then he will start to cry to prove his point.
