Russian scientists challenge 'man-made' global warming theory.

 “We found that the level of CO2 had fluctuated greatly over the period but at any given time increases in air temperature preceded higher concentrations of CO2,” says academician Kapitsa, who worked in Antarctica for many years. Russian studies showed that throughout history, CO2 levels in the air rose 500 to 600 years after the climate warmed up. Therefore, higher concentrations of greenhouse gases registered today are the result, not the cause, of global warming. Critics of the CO2 role in climate change point out that water vapours are a far more potent factor in creating the greenhouse effect as their concentration in the atmosphere is five to 10 times higher than that of CO2. “Even if all CO2 were removed from the earth atmosphere, global climate would not become any cooler,” says solar physicist Vladimir Bashkirtsev. The hypothesis of anthropogenic greenhouse gases was born out of computer modelling of climate changes. Russian scientists say climate models are inaccurate si

Global Warming Scientist Comes Clean

 1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it. Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most... We have been measuring the atmosphere for decades using radiosondes: weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. They show no hot spot. Whatsoever. If there is no hot spot then an increased greenhouse effect is not the cause of global warming. 2. There is no evidence that carbon emissions cause significant global warming. None. ... 3. The satellites that measure the world's temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6C in the past year 4. ice cores show that in the past... half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon.

The Sunspot Enigma: The Sun is “Dead”—What Does it Mean for Earth?
papananook
by papananook  7-2-2008    3
  And here's the kicker--We may have an ice age while preparing for global warming---are you cackling in glee yet, Willhelm? Geophysicist Phil Chapman, the first Australian to become an astronaut with NASA, said pictures from the US Solar and Heliospheric Observatory also show that there are currently no spots on the sun. He also noted that the world cooled quickly between January last year and January this year, by about 0.7C. "This is the fastest temperature change in the instrumental record, and it puts us back to where we were in 1930," Dr Chapman noted in The Australian recently. If the world does face another mini Ice Age, it could come without warning. Evidence for abrupt climate change is readily found in ice cores taken from Greenland and Antarctica. One of the best known examples of such an event is the Younger Dryas cooling, which occurred about 12,000 years ago, named after the arctic wildflower found in northern European sediments. This event began and ended rat

Ice Cores Map Dynamics Of Sudden Climate Changes
Socratoad
by Socratoad  6-24-2008   
 he first sudden warming happened 14,700 years ago. The temperature in Greenland increased by more than 10 degrees, and in the milder climate, called the Bølling period, the first people of the Stone Age went towards Northern Europe and Scandinavia. But joy did not last long. 12,900 years ago the ice age stroke once more with a new severely cold period, which lasted until 11,700 years ago, at which time the ice age ended ultimately. The ice cores from Greenland, which reflect the climate in the Northern Hemisphere, show that tremendously fast climatic changes were involved. The ice age ended in one year

 "The coring equipment and other instrumentation was set up using a tripod over the hole in the ice. The scientists were able to extract a core of the topmost 8.5 meters of sediment. The international team of researchers in the field included Guillaume St-Onge; Reinhard Pienitz, principal investigator; Veli-Pekka Salonen of the University of Helsinki, Finland; and Richard Niederreiter, coring expert.

Chinese Climate Records::100 AD ' Was Warmer Then'
merrie
by merrie  11-5-2007    1
 The Chinese researchers also looked at modern proxy evidence of past temperatures. * The oxygen isotopes in ice cores yield an annual record of the air temperatures when the ice was laid down. The researchers looked at two ice cores from Tibet. * Trees respond to warmth and rainfall by growing more rapidly, and the Chinese researchers examined two tree ring records from China and one from nearby Japan. * They included analysis of pollen and organic matter in a deep peat bog on the edge of the Tibetan Plateau. * They examined sediment cores from two lake beds in Taiwan. From this evidence, the Chinese researchers concluded China's warmest period during the past 2000 years occurred around 100 AD. This aligns with Roman records of growing wine grapes in Britain during their occupation of that island in the first century--even though Britain was unable to grow wine grapes from 1300 to 1950 because of too-cold temperatures

Earth could 'flip' into environmental disaster
jetcloud
by jetcloud  6-21-2007    1
 The study looked back over more than 400,000 years of climate records from deep ice cores and found evidence to suggest that rapid climate change over a period of centuries, or even decades, have in the past occurred once the world began to heat up and ice sheets started melting. "The unnatural "forcing" of the climate as a result of man-made emissions of carbon dioxide and other greenhouse gases threatens to generate a "flip" in the climate that could "spark a cataclysm" in the ice sheets of Antarctica and Greenland. Dramatic climatic flips have occurred in the past but none has happened since the development of complex human societies, which are unlikely to survive the same sort of environmental changes if they occurred now." It has already flipped, contrails, shiptrails, and other trails have , so far, saved the earth. jc

More Climate Change Myths
Lembit
by Lembit  6-5-2007   
 Continued... Basic physics tells us that gases with this property trap heat radiating from the Earth, that the planet would be a lot colder if this effect was not real and that adding more CO2 to the atmosphere will trap even more heat. What is more, CO2 is just one of several greenhouses gases, and greenhouse gases are just one of many factors affecting the climate. There is no reason to expect a perfect correlation between CO2 levels and temperature in the past: if there is a big change in another climate "forcing", the correlation will be obscured. So why has Earth regularly switched between ice ages and warmer interglacial periods in the past million years? It has long been thought that this is due to variations in Earth's orbit. However, the correlation is not perfect and the heating or cooling effect of these orbital variations is small. It has also long been recognised that they cannot fully explain the dramatic temperature switches between ice ages and interglacials.

Foremost expert in climatology debunks "global warming" hysteria
pkronfield

 This guy says the global warming hysteria is nonsense: Reid A. Bryson holds the 30th PhD in Meteorology granted in the history of American education. Emeritus Professor and founding chairman of the University of Wisconsin Department of Meteorology—now the Department of Oceanic and Atmospheric Sciences—in the 1970s he became the first director of what’s now the UW’s Gaylord Nelson Institute of Environmental Studies. He’s a member of the United Nations Global 500 Roll of Honor—created, the U.N. says, to recognize “outstanding achievements in the protection and improvement of the environment.” He has authored five books and more than 230 other publications and was identified by the British Institute of Geographers as the most frequently cited climatologist in the world.
