Global Warming Or Ice Age Return Who Knows?
The link between Solar ‘moods’ and the weather down here on Earth was first noticed in the 1970s, when the American astronomer Jack Eddy noticed a strong correlation between historic weather records and contemporaneous accounts of Solar activity, most notably the long record of sunspots published a century before by the astronomer Edward Maunder.
Eddy noticed that a ‘quiet’ Sun correlates with cold weather and a manic phase means warmer conditions.
His best evidence for this link comes from the last time the Sun went to sleep, the so-called ‘Maunder Minimum’ period from 1645 to 1715.
During this period and for about a century either side, much of Europe and North America suffered a succession of bitterly cold winters and damp washout summers - the ‘little ice age’ this was a time when the ice on London’s River Thames was regularly a foot deep and when thousands went hungry because crops froze in the fields.
Scientists from the German Research Centre for Geosciences GFZ in collaboration with Swedish and Dutch colleagues provide evidence for a direct solar-climate linkage on centennial timescales,' say the researchers.
'Using the most modern methodological approach, they analysed sediments from Lake Meerfelder Maar, a maar lake in the Eifel/Germany, to determine annual variations in climate and solar activity.'
Suggestions that the sun might affect climate so profoundly are controversial.
Mankind’s use of fossil fuels has led to billions of tons of carbon dioxide being pumped into the atmosphere, triggering global temperature rises from which experts believe we will take millennia to recover. That is the consensus view.
“So who knows are we heading for an ice age? Or global warming, seems like nobody really knows what the weather has in store for us” says Greengates Builders Merchants Accrington, Lancashire.
