The Other Climate Change Factors.....

Volcanoes and sunspot activity have an interrelated impact on global climate [from my Alma Mater]....

University at Buffalo scientists working with ice cores have solved a mystery surrounding sunspots and their effect on climate that has puzzled scientists since they began studying the phenomenon.
The research, published in a paper in the May 15 issue of Geophysical Research Letters, provides striking evidence that sunspots -- blemishes on the sun's surface indicating strong solar activity -- do influence global climate change, but that explosive volcanic eruptions on Earth can completely reverse those influences.

But of course, the UN [and Al Gore, who also invented the Internet] has all the answers to the threat of global warming, as understood today, and certain people don't want and aren't interesting in debating issues surrounding the science and debate is what makes science work.
