Are you as tired of hearing coffee is bad for you one day and good for you the next? Or that eggs are unhealthy one day and the next morning they say you should eat them? Well, apparently it is the same with global warming. A “respected” group of scientists have now determined that our sun is going into a period of inactivity (no sun-spots) and that this will mean we will have a mini-ice age. Rivers, such as the Thames, that normally do not get much, if any, ice will freeze over and lower altitudes will have a year-round coating of snow.
Wait, what’s that? What about the “Global Warming” and the end of the earth? I thought we were on the verge of seeing the polar ice cap disappear and the oceans raising up and swallowing Florida? Well, gee, that was last week. This week the Polar Bears are safe and we all need to buy heavy coats and snow shoes.
What may be the science story of the century is breaking as heavyweight US solar physicists announced that the Sun appears to be headed into a lengthy spell of low activity, which could mean that the Earth – far from facing a global warming problem – is actually headed into a mini Ice Age.
The announcement made on 14 June comes from scientists at the US National Solar Observatory (NSO) and US Air Force Research Laboratory. Three different analyses of the Sun's recent behavior all indicate that a period of unusually low solar activity may be about to begin.
The Sun normally follows an 11-year cycle of activity. The current cycle is now supposed to be ramping up towards maximum strength. Increased numbers of sunspots and other indications ought to be happening: but in fact results so far are most disappointing. Scientists at the NSO now suspect, based on data showing decades-long trends leading to this point, the next cycle may not happen at all. This could have major implications for the Earth's climate. According to a statement issued by the NSO, announcing the research:
An immediate question is whether this slowdown presages a second Maunder Minimum, a 70-year period with virtually no sunspots which occurred during from 1645 to1715.As NASA notes:Early records of sunspots indicate that the Sun went through a period of inactivity in the late 17th century. Very few sunspots were seen on the Sun from about 1645 to 1715. Although the observations were not as extensive as in later years, the Sun was in fact well observed during this time and this lack of sunspots is well documented. This period of solar inactivity also corresponds to a climatic period called the "Little Ice Age" when rivers that are normally ice-free froze and snow fields remained year-round at lower altitudes. There is evidence that the Sun has had similar periods of inactivity in the more distant past.
During the Maunder Minimum and for periods either side of it, many European rivers which are ice-free today – including the Thames – routinely froze over, allowing ice skating and even for armies to march across them in some cases.
"This is highly unusual and unexpected," says Dr Frank Hill of the NSO. "But the fact that three completely different views of the Sun point in the same direction is a powerful indicator that the sunspot cycle may be going into hibernation."
Hey, don’t panic and don’t get too worried about all of this. I am quite sure that by next week they will find some other way to predict the end of the world –and if all else fails you can always fall back on the Mayan Calendar prediction, that s only 16 months away…
Live Long and Prosper....
