Over 95% of the greenhouse affect comes from water vapor.  Co2 isn't nearly the most potent Nd human beings only represent  minority of cow production...

There isn't a historical causal relationship between co2 levels and surface temperatures.  In fact according to the ice cores the OPPOSITE is true.  

There have been times in the Earths history when there were no or very little ice caps.  

The giant fusion engine that provides 99.999999999999999999999999 of the energy on the planet has power cycles.

Last but not least the earth has been warming and cooling for all of its 4.1 billion years.  Glacial periods, ice ages, tropical climates etc.

Some of what you wrote is correct.
The sun's output really does vary over time.
however, ever since Sputnik, the scientists have been able to measure this without the Earth's atmosphere getting in the way.
There have found that the solar output is actually a little bit down over the last 50 years.
Meanwhile, we have more and more record-breaking years in terms of Earth's high surface temperature.
Even while solar output is down.
Do you have an explanation for that?
