    Another example of why the so called "environmentalists" don't know S**T!

    Middle Ages were warmer than today, say scientists

    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.

    "When the temperature started to drop, harvests failed and England's vine industry died.

    So this means that we can look forward to a thriving English Wine industry soon? That'll piss off the Australians....lol

    Expatbrit, amused to see the drunk potheads at the University of East Anglia screw up yet again!

    It shows how a little bit of knowledge is a dangerous thing.

    I would like to add that if one takes an even longer historical view, one will discover that we have had very significant global warming for over 12,000 years, long before man had any influence whatsoever. Remember the last ice age? At its worse, glaciers extended all the way to southern Ohio, where I live. Twelve thousand years ago, they still covered the upper peninsula of Michigan. During this long term warming trend, there were periods where the earth warmed at ten times the rate it is warming today. Short term trends can be explained by the natural cycles of the sun's production of energy, rather than man's influence on the planet. If the human race is having an impact, it is minimal in the scheme of things.

    finally a topic where we agree!

    this whole global warming thing is completely overdone... have you looked at solar activity and the solar cycles? look up gleissberg cycel for instance! its very interesting!

    You are soo right ThiChi,

    I took several Geology and Paleontology classes which all confirmed from numerous lines of evidence that drastic climate changes throughout the Earth's history are the rule rather than the exception. For instance, the average global temp as late as 65 million years ago was 90 degrees F., way higher than today's averages. Human beings could not possibly be responsible for this "global warming" since we were still at the technology level of today's bush babies munching flowers and insects in the trees at this time. Evidence from many periods prove that we have gone from ice age to hot house over & over again without the help of human industry. The same goes for ozone depleting chemicals which valcanoes spew by the ton without our help. The whole Global Warming/Ozone Hole conspiracy is utter nonsense invented by post modernist Ludites.

    While I agree that knee-jerk reactions are not good, as seems to be the case with some environmentalists,

    I can't imagine that pumping billions of tons of CO2 into the atmosphere, year after year, is a good thing. The increasing desertification of the earth scares me.

    So, as always I find myself somewhere in the middle.

    All the computers in the world put together probably couldn't take into account all the factors that affect our climate, so both sides need humility, none of this "OK you're wrong, here's the facts, case closed" stuff.

    Dan, while I agree that putting lots of CO2 into the atmosphere is not a good thing. Deforestation is not good either. The question is, how much impact does this have on any warming trend? Reviewing what I wrote, along with the comments of others, I still conclude that our impact as a species is minimal. I think the forces of nature, with or without our presence, are vastly more powerful than our puny intrusion.

    I distinctly remember that noted scientific journal AWAKE magazine having its say on this issue. Back in the 1970's they had an article about how COLD the earth was getting. They showed a planet earth with a sick face on it, shivering, with a thermometer in its "mouth".

    Then in the 1980's, they come out with an article on, that's right, Global Warming!!

    So which one is happening, global cooling, or global warming? Or phases of both.

    It seems that they'll print whatever, and then go seek "evidence" to support their current idea. Journals of truth, whatever!

  • larc

    Gopher, back in the 50's, many scientists thought we were headed for another ice age. So the Awake simply prints what is most widely accepted at the time. Kind of like a real dumbed down Reader's Digest article, is what you'll find in the Awake.
