To the Horror of Global Warming Alarmists, Global Cooling Is Here [View all]

Around 1250 A.D., historical records show, ice packs began showing up farther south in the North Atlantic. Glaciers also began expanding on Greenland, soon to threaten Norse settlements on the island. From 1275 to 1300 A.D., glaciers began expanding more broadly, according to radiocarbon dating of plants killed by the glacier growth. The period known today as the Little Ice Age was just starting to poke through.

The Little Ice Age, following the historically warm temperatures of the Medieval Warm Period, which lasted from about AD 950 to 1250, has been attributed to natural cycles in solar activity, particularly sunspots. A period of sharply lower sunspot activity known as the Wolf Minimum began in 1280 and persisted for 70 years until 1350. That was followed by a period of even lower sunspot activity that lasted 90 years from 1460 to 1550 known as the Sporer Minimum. During the period 1645 to 1715, the low point of the Little Ice Age, the number of sunspots declined to zero for the entire time. This is known as the Maunder Minimum, named after English astronomer Walter Maunder. That was followed by the Dalton Minimum from 1790 to 1830, another period of well below normal sunspot activity.

At first the current stall out of global warming was due to the ocean cycles turning back to cold. But something much more ominous has developed over this period. Sunspots run in 11 year short term cycles, with longer cyclical trends of 90 and even 200 years. The number of sunspots declined substantially in the last 11 year cycle, after flattening out over the previous 20 years. But in the current cycle, sunspot activity has collapsed. NASA’s Science News report for January 8, 2013 states, “Indeed, the sun could be on the threshold of a mini-Maunder event right now. Ongoing Solar Cycle 24 [the current short term 11 year cycle] is the weakest in more than 50 years. Moreover, there is (controversial) evidence of a long-term weakening trend in the magnetic field strength of sunspots. Matt Penn and William Livingston of the National Solar Observatory predict that by the time Solar Cycle 25 arrives, magnetic fields on the sun will be so weak that few if any sunspots will be formed. Independent lines of research involving helioseismology and surface polar fields tend to support their conclusion.”

Faith in Global Warming is collapsing in formerly staunch Europe following increasingly severe winters which have now started continuing into spring. Christopher Booker explained in The Sunday Telegraph on April 27, 2013, "Here in Britain, where we had our fifth freezing winter in a row, the Central England Temperature record – according to an expert analysis on the US science blog Watts Up With That – shows that in this century, average winter temperatures have dropped by 1.45C, more than twice as much as their rise between 1850 and 1999, and twice as much as the entire net rise in global temperatures recorded in the 20th century.”
