More info on the "global warming" scam



Nothing more than a method to shift trillions of $'s to the Third
World
from the First.  Despite all the contrary evidence cropping up, the
IPCC
 STILL thinks they can predict climate out 100 years when the best
computer
models can't predict weather for a week.

>From the Guardian:

Middle Ages were warmer than today, say scientists By Robert Matthews,
Science Correspondent(Filed: 06/04/2003) Claims that man-made
pollution is causing "unprecedented" global warming have been
seriously undermined by new research which shows that the Earth was
warmer during the Middle Ages.From the outset of the global warming
debate in the late 1980s, environmentalists have said that
temperatures are rising higher and faster than ever before, leading
some scientists to conclude that greenhouse gases from cars and power
stations are causing these "record-breaking" global temperatures.Last
year, scientists working for the UK Climate Impacts Programme said
that global temperatures were "the hottest since records began" and
added: "We are pretty sure that climate change due to human activity
is here and it's accelerating."This announcement followed research
published in 1998, when scientists at the Climatic Research Unit at
the University of East Anglia declared that the 1990s had been hotter
than any other period for 1,000 years.Such claims have now been
sharply contradicted by the most comprehensive study yet of global
temperature over the past 1,000 years. A review of more than 240
scientific studies has shown that today's temperatures are neither the
warmest over the past millennium, nor are they producing the most
extreme weather - in stark contrast to the claims of the
environmentalists.The review, carried out by a team from Harvard
University, examined the findings of studies of so-called "temperature
proxies" such as tree rings, ice cores and historical accounts which
allow scientists to estimate temperatures prevailing at sites around
the world.The findings prove that the world experienced a Medieval
Warm Period between the ninth and 14th centuries with global
temperatures significantly higher even than today.They also confirm
claims that a Little Ice Age set in around 1300, during which the
world cooled dramatically. Since 1900, the world has begun to warm up
again - but has still to reach the balmy temperatures of the Middle
Ages.The timing of the end of the Little Ice Age is especially
significant, as it implies that the records used by climate scientists
date from a time when the Earth was relatively cold, thereby
exaggerating the significance of today's temperature rise. According
to the researchers, the evidence confirms suspicions that today's
"unprecedented" temperatures are simply the result of examining
temperature change over too short a period of time.The study, about to
be published in the journal Energy and Environment, has been welcomed
by sceptics of global warming, who say it puts the claims of
environmentalists in proper context. Until now, suggestions that the
Middle Ages were as warm as the 21st century had been largely
anecdotal and were often challenged by believers in man-made global
warming.Dr Philip Stott, the professor emeritus of bio-geography at
the University of London, told The Telegraph: "What has been forgotten
in all the discussion about global warming is a proper sense of
history."According to Prof Stott, the evidence also undermines
doom-laden predictions about the effect of higher global temperatures.
"During the Medieval Warm Period, the world was warmer even than
today, and history shows that it was a wonderful period of plenty for
everyone."In contrast, said Prof Stott, severe famines and economic
collapse followed the onset of the Little Ice Age around 1300. He
said: "When the temperature started to drop, harvests failed and
England's vine industry died. It makes one wonder why there is so much
fear of warmth."The United Nation's Intergovernmental Panel on Climate
Change (IPCC), the official voice of global warming research, has
conceded the possibility that today's "record-breaking" temperatures
may be at least partly caused by the Earth recovering from a
relatively cold period in recent history. While the evidence for
entirely natural changes in the Earth's temperature continues to grow,
its causes still remain mysterious.Dr Simon Brown, the climate
extremes research manager at the Meteorological Office at Bracknell,
said that the present consensus among scientists on the IPCC was that
the Medieval Warm Period could not be used to judge the significance
of existing warming.Dr Brown said: "The conclusion that 20th century
warming is not unusual relies on the assertion that the Medieval Warm
Period was a global phenomenon. This is not the conclusion of IPCC."He
added that there were also doubts about the reliability of temperature
proxies such as tree rings: "They are not able to capture the recent
warming of the last 50 years," he said.
