Solar Cycle Shutting Down: New Ice Age Next?

"The sunspot cycle may be going into hibernation," says Frank Hill of the National Solar Observatory in Sunspot, New Mexico. He and other researchers are presenting their findings this week at a meeting of the American Astronomical Society's Solar Physics Division in Las Cruces, New Mexico.

...The sun's solar cycle was interrupted once before during the so-called Maunder minimum from 1645 to 1715, when almost no sunspots appeared.

Some scientists have suggested this 70-year lull may have triggered or contributed to the pronounced cooling observed in northern Europe during this period... _NS

Solar scientists do not understand what is up with the sun these days. Just as physicists are discovering that the sun may be driving the climate, solar scientists are frantically trying to understand what is driving the sun. Because if the sun does decide to shut down for a while, things on Earth may grow very cold of a sudden.
Three different lines of evidence suggest that the sun, which is expected to reach its maximum sunspot and magnetic activity in the current cycle in 2013, might even be entering a prolonged quiet period similar to the so-called Maunder Minimum, a 70-year period from 1645 to 1715 in which virtually no sunspots were observed. _SMH
It has been clear for some time that global climate closely tracks solar activity, mediated largely via clouds and ocean oscillations. But scientists are still in a fog as far as understanding the controlling forces of solar cycles.
A missing jet stream, fading spots, and slower activity near the poles say that our Sun is heading for a rest period even as it is acting up for the first time in years, according to scientists at the National Solar Observatory (NSO) and the Air Force Research Laboratory (AFRL)....All three of these lines of research to point to the familiar sunspot cycle shutting down for a while.

“If we are right,” Hill concluded, “this could be the last solar maximum we’ll see for a few decades. That would affect everything from space exploration to Earth’s climate.” _WUWT

Scientists are forced to monitor second and third order phenomena, and to guess at the primary -- likely chaotic -- forces at the heart of the sun, which control the observable phenomena. As for the climate of tiny planet Earth, it is at the mercy of cosmic forces.

When unscrupulous politicians and grant-hungry climatologists scream for greater funding and more control over government budgets and economic activity -- that is clearly self-interest talking. But when voters, citizens, and the public at large take these climate grifters seriously -- that is the Idiocracy.

Remember, global cooling is far more devastating than global warming. Global cooling leads to widespread crop failures and a dramatic drop in agricultural yield. Another "little ice age," such as occurred the last time the sun went to sleep, could lead to hundreds of millions of human deaths from starvation and associated disease and warfare. Or worse. Because without current huge agricultural yields from temperate climate crops, the world's human population would be too large to sustain, as per Malthus.
