Is 'global cooling' on the way? Lake sediment proves sun cooled earth 2,800 years ago - and it could happen again soon
- Lake sediment proves 'solar minimum' caused 200 years of cooling 2,800 years ago
- New minimum due soon - after this year's increased sunspot activity
- Sun's activity CAN cause changes in Earth's climate, claim scientists
- May throw predictions of global warming out of whack

When the Greek poet Homer was writing
The Odyssey around 2,800 years ago, the Earth went through an abrupt
period of cooling, caused by the sun - and the same could happen again
soon.
Scientists at the GFZ
German Research Centre for Geosciences analysed lake sediment in Lake
Meerfelder Maar, and found direct evidence of a sudden cooling caused by
a 'solar minimum'.
Some
scientists suspect that the current period of high solar activity -
including increased sunspots and solar storms thsi year - will be
followed by a 'minimum' period, which could even cause an Ice Age.
f the GFZ research is correct, a new
'solar minimum' could have a direct impact on Earth's climate - cooling
our planet drastically, and knocking the predictions of global-warming
alarmists out of whack.
Dr
Achim Brauer of the GFZ said,'An abrupt cooling in Europe together with
an increase in humidity and particularly in windiness coincided with a
sustained reduction in solar activity 2800 years ago.'
Brauer's measurement's of lake sediments allow 'a precise dating even of short-term climate changes.'
The
'Homeric Minimum' - the solar minimum that coincided with the famous
poet's lifetime - caused a cool period that lasted 200 years.
'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.
Three
centuries ago similar changes in the Sun were linked to a period of
almost unprecedented cold, known as the ‘little ice-age’ - 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.
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’
