The Global Warming Hoax: A Summary

From Powerline: 

This week's SEPP newsletter includes an excellent piece by Dr. Harrison "Jack" Schmitt, a former United States Senator from New Mexico as well as a geologist and former Apollo astronaut who currently is an aerospace consultant. Dr. Schmitt reviews some of the basic evidence that the alarmists try to wish away.

There has been an absolute natural increase in global surface temperature of half a degree Centigrade per 100 years (0.9 degrees Fahrenheit) over the last three and a half centuries. Observational climate data and objective interpretations of those data strongly indicate that nature, not human activity, exerts the primary influence on this current long term warming and on all global climate variations. Human influence through use of fossil fuels has been and remains minor if even detectable. Claims to the contrary only find support in highly questionable climate models that fail repeatedly against the reality of nature. What, then, stimulates historically and geologically observed, sometimes slow and sometimes radical, changes in climate?

The primary alternative hypothesis to human-caused global warming is natural climate change driven by the Sun.

Imagine: the main factor influencing the Earth's temperature is the sun.  Who would have imagined it?
