Our sun is behaving in what some scientists think is a peculiar manner. Will the global-warming myth be exploded?
"The disappearance of sunspots happens every few years, but this time it?s gone on far longer than anyone expected ? and there is no sign of the Sun waking up. ?This is the lowest we?ve ever seen. We thought we?d be out of it by now, but we?re not,? says Marc Hairston of the University of Texas. And it?s not just the sunspots that are causing concern. There is also the so-called solar wind ? streams of particles the Sun pours out ? that is at its weakest since records began. In addition, the Sun?s magnetic axis is tilted to an unusual degree. ?This is the quietest Sun we?ve seen in almost a century,? says NASA solar scientist David Hathaway. But this is not just a scientific curiosity. It could affect everyone on Earth and force what for many is the unthinkable: a reappraisal of the science behind recent global warming.
Our Sun is the primary force of the Earth?s climate system, driving atmospheric and oceanic circulation patterns. It lies behind every aspect of the Earth?s climate and is, of course, a key component of the greenhouse effect. But there is another factor to be considered. When the Sun has gone quiet like this before, it coincided with the earth cooling slightly and there is speculation that a similar thing could happen now. If so, it could alter all our predictions of climate change, and show that our understanding of climate change might not be anywhere near as good as we thought."
