"Spin-orbit coupling" to blame; effects could last decades. A new paper published by the Astronomical Society of Australia is warning of upcoming global cooling due to lessened solar activity. The study, written by three Australian researchers, has identified what is known as a "spin-orbit coupling" affecting the rotation rate of the sun. That rotation, in turn, is linked to the intensity of the solar cycle and climate changes here on Earth. The study's lead author, Ian Wilson, explains further, "[The paper] supports the contention that the level of activity on the Sun will significantly diminish sometime in the next decade and remain low for about 20 - 30 years." According to Wilson, the result is a strong, rapid pulse of global cooling, "On each occasion that the Sun has done this in the past the World’s mean temperature has dropped by ~ 1 - 2 C." A 2 C drop would be twice as large as all the warming the earth has experienced since the start of the industrial era, and would be significant enough to impact global agriculture output. Earlier this year, astronomers from around the world noted solar activity was suspiciously low; some began predicting global cooling at that time. Since then, activity has remained far below average, with it now being over two months since a single sunspot has appeared on the surface of the sun. In May, a team of German climatologists published research stating that, due to "natural effects", global warming would halt for up to 15 years. The new paper appears in the June issue of PASA, Publications of the Astronomical Society of Australia.

Landscheidt minimum here we come.
Did you notice the graph on the source page of your article, and the caption below it? It states "A 2005 prediction of solar activity. The sunspot number should now stand close to 100, instead it is zero." It is obvious that whoever wrote that is hoping that his readers all just swallow whatever is handed them as gospel. Solar cycle 23 did NOT end in 2004 and solar activity did NOT drop to its minimum in 2006, it occured THIS year instead. The last cycle, cycle 23, lasted several years longer than shown in this graph. The authors should have known that. Again, here's an actual graph showing actual solar activity up to the end of May 2008.
Globally, the Earth is a bit warmer than last month with the anomalies for June 2008: Global -0.317 C, NH +0.004 C, and SH -0.232 C. 2007 figures were 0.203 C, 0.375 C and 0.03 C repectively. The CO2 concentration [Mauna Loa] has gone down from 388.49 ppmv in May 2008 to 388.0 ppmv in June 2008. Comapared with June 2007 [385.98 ppmv] the CO2 concentration has risen to 388.0 ppmv, an increase of 2 ppmv over the year. It was expected in certain circles that CO2 totals would start to drop as cooling set in.
