"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.

This is typical alarmist bullshit written by those who should know better, and more than likely do. There have been articles floating around recently with dire predictions on "global cooling" since there are few sunspots occuring right now. Any scientist who can honestly refer to him or herself as such should know that we are currently in the minimum swing of the new solar cycle, where activity is about to pick up in a month or so. Here's a graph of solar activity dating back to the year 2000. The graph starts at the peak of the former solar cycle and goes up to the year 2016, which is towards the end of the current cycle which began in January of this year. The current cycle is not expected to peak until 2012, and is thought to more than likely be a VERY active cycle. We ARE however at the minimum point of activity in the new cycle, where there are still sunspots occuring from the prior cycle. A new cycle is determined by the appearance of sunspots of the opposite polarity from that of the former cycle. The first sunspot of the new cycle, cycle 24, appeared on January 4th of this year. There are two expected activity curves in red, one being the minimum activity, the other the maximum. Here's a couple of graphs showing solar activity back to 1760. As you can see, there is nothing unique or unusual with our current point in the solar cycle. One has to wonder why scientists who should know better are publishing such utter crapola.
