Scientist: Global COOLING Causes More Extreme Weather, More Frequent
Droughts And Floods!
Leftists/warmists just can't make up their minds!
Is more extreme wether caused by warming?
Or perhaps caused by cooling!
In 1975, Science News published the graph below of northern hemisphere
temperatures, from the National Academy of Sciences.
Since 1940, the temperature of the Northern Hemisphere has been steadily
falling:
Having risen about 1.1ºC. between 1885 and 1940, according to one
estimation, the temperature has already fallen back some 0.6ºC, and shows no
signs of reversal
To gain a perspective on these divergent views, SCIENCE NEWS interviewed C.
C. Wallen, chief of the Special Environmental Applications Division, World
Meteorological Organization, at the WMO headquarters in Geneva.
The cooling trend observed since 1940 is real enough, he says, but not
enough is known about the underlying causes to justify any sort of
extrapolation. Particularly dangerous would be any attempt to generalize
from even shorter-term experience, like the bad weather in 1972 and
following years, to prognosticate any future weather patterns.
On the other hand, the cooling since 1940 has been large enough and
consistent enough that it will not soon be reversed, and we are unlikely to
quickly regain the "very extraordinary period of warmth" that preceded it.
Even this mild diagnosis can have "fantastic implications" for present-day
humanity, Wallen says.
THE PRINCIPAL WEATHER CHANGE LIKELY TO ACCOMPANY THE COOLING TREND IS
INCREASED VARIABILITY - ALTERNATING EXTREMES OF TEMPERATURE AND PRCIPITATION
IN ANY GIVEN AREA
- which would almost certainly lower average crop yields.
The cause of this increased variability can best be seen by examining upper
atmosphere wind patterns that accompany
cooler climate.
During warm periods a "zonal circulation" predominates, in
which the prevailing westerly winds of the temperate zones are swept over
long distances by a few powerful high
and low pressure centers.
The result is a more evenly distributed pattern of
weather, varying relatively little from month to month or season to season.
During cooler climatic periods, however, the high-altitude winds are broken
up into irregular cells by weaker and
more plentiful pressure centers, causing formation of a "meridional
circulation" pattern.
These small, weak cells may stagnate over vast areas for many months,
bringing unseasonably cold weather on one side and unseasonably warm weather
on the other.
DROUGHTS AND FLOODS BECOME MORE FREQUENT AND MAY ALTERNATE SEASON TO SEASON
AS THEY DID LAST YEAR IN INDIA.
THUS, WHILE THE HEMISPHERE AS A WHOLE IS COOLER, INDIVIDUAL AREAS MAY BREAK
TEMPERATURE AND PRECIPITATION RECORDS AT BOTH EXTREMES.

"It is a remarkable fact that despite the worldwide expenditure of perhaps
US$50 billion since 1990, and the efforts of tens of thousands of scientists
worldwide, no human climate signal has yet been detected that is distinct
from natural variation."
Bob Carter, Research Professor of Geology, James Cook University, Townsville
"A major problem has been the co-option of climate science by politics,
ambition, greed, and what seems to be a hereditary human need for a
righteous cause."
"What better cause than "saving" the planet, especially if one can get
ample, secure funding at the same time?"
William Happer, Cyrus Fogg Brackett Professor of Physics, Princeton
University.
"The claim is that the temperature has changed from ~288.0 to ~288.8ºK in
about 150 years, which, if true, means to me that the temperature has been
amazingly stable, and both human health and happiness have definitely
improved in this 'warming' period,".
Nobel Laureate Dr. Ivar Giaever:
"If climate has not "tipped" in over 4 billion years it's not going to tip
now due to mankind. The planet has a natural thermostat"
Richard S. Lindzen, Atmospheric Physicist, Professor of Meteorology MIT,
Former IPCC Lead Author
"A core problem is that science has given way to ideology. The scientific
method has been dispensed with, or abused, to serve the myth of man-made
global warming."
"The World Turned Upside Down", Melanie Phillips
"Computer models are built in an almost backwards fashion: The goal is to
show evidence of AGW, and the "scientists" go to work to produce such a
result. When even these models fail to show what advocates want, the data
and interpretations are "fudged" to bring about the desired result"
"The World Turned Upside Down", Melanie Phillips
"Ocean acidification looks suspiciously like a back-up plan by the
environmental pressure groups in case the climate fails to warm: another try
at condemning fossil fuels!"

Before attacking hypothetical problems, let us first solve the real problems
that threaten humanity. One single water pump at an equivalent cost of a
couple of solar panels can indeed spare hundreds of Sahel women the daily
journey to the spring and spare many infections and lives.
Martin De Vlieghere, philosopher
"All it takes to find oneself called a 'denier' is to seek a sense of
proportion about environmental problems"
Mark Lynas, The God Species
