    It just goes to prove that a statement repeated over and over will eventually be accepted as truth.

    There are lot of folks who benefit from the belief that global warming is caused by man. There are the universities who get government funds to keep studying this fake phenomenon. There is also the government who can "scare" the public into thinking that they need government to help with this "problem." Government can use this as a vehicle to tax industries on CO2 emittance.

    There is a ton of evidence that climate change is caused by cycles and cannot by changed by man.

    But mother nature has opinions of her own. NASA now begrudgingly confirms that the hottest year on record in the continental 48 was not 1998, as previously believed, but 1934, and that six of the 10 hottest years since 1880 antedate 1954. Data from 3,000 scientific robots in the world's oceans show there has been slight cooling in the past five years, never mind that "80% to 90% of global warming involves heating up ocean waters," according to a report by NPR's Richard Harris.

    The Arctic ice cap may be thinning, but the extent of Antarctic sea ice has been expanding for years. At least as of February, last winter was the Northern Hemisphere's coldest in decades. In May, German climate modelers reported in the journal Nature that global warming is due for a decade-long vacation. But be not not-afraid, added the modelers: The inexorable march to apocalypse resumes in 2020.

    This last item is, of course, a forecast, not an empirical observation. But it raises a useful question: If even slight global cooling remains evidence of global warming, what isn't evidence of global warming? What we have here is a nonfalsifiable hypothesis, logically indistinguishable from claims for the existence of God. This doesn't mean God doesn't exist, or that global warming isn't happening. It does mean it isn't science.


    Hey, what about global warming on Mars. It must be all those SUV's out there...

    FIRST COMPILATION OF TROPICAL ICE CORES SHOWS TWO ABRUPT GLOBAL CLIMATE SHIFTS ONE 5,000 YEARS AGO AND ONE CURRENTLY UNDERWAY
    COLUMBUS , Ohio For the first time, glaciologists have combined and compared sets of ancient climate records trapped in ice cores from the South American Andes and the Asian Himalayas to paint a picture of how climate has changed and is still changing in the tropics.






    Lonnie Thompson
    Their conclusions mark a massive climate shift to a cooler regime that occurred just over 5,000 years ago, and a more recent reversal to a much warmer world within the last 50 years.

    The evidence also suggests that most of the high-altitude glaciers in the planet's tropical regions will disappear in the near future. The paper is included in the current issue of the journal Proceedings of the National Academy of Science.

    Lastly, the research shows that in most of the world, glaciers and ice caps are rapidly retreating, even in areas where precipitation increases are documented. This implicates increasing temperatures and not decreasing precipitation as the most likely culprit.

    The researchers from Ohio State University's Byrd Polar Research Center and three other universities combined the chronological climate records retrieved from seven remote locations north and south of the equator. Cores drilled through ice caps and glaciers there have captured a climate history of each region, in some cases, providing annual records and in others decadal averages.

    Approximately 70 percent of the world's population now lives in the tropics so when climate changes there, the impacts are likely to be enormous, explains Lonnie Thompson, professor of geological sciences at Ohio State.

    For the last three decades, Thompson has led nearly 50 expeditions to remote ice caps and glaciers to drill cores through them and retrieve climate records. This study includes cores taken from the Huascaran and Quelccaya ice caps in Peru; the Sajama ice cap in Bolivia; the Dunde, Guliya, Puruogangri and Dasuopu ice caps in China.

    For each of these cores, the team -- including research partner Ellen Mosley-Thompson, professor of geography at Ohio State extracted chronological measurements of the ratio of two oxygen isotopes -- O18 and O16 -- whose ratio serves as an indicator of air temperature at the time the ice was formed. All seven cores provided clear annual records of the isotope ratios for the last 400 years and decadally averaged records dating back 2000 years.


    --------------------------------------------------------------------------------

    Our climate system is sensitive, and it can change abruptly due to either natural or to human forces. If what happened 5,000 years ago were to happen today, it would have far-reaching social and economic implications for the entire planet. The take-home message is that global climate can change abruptly, and with 6.5 billion people inhabiting the planet, that's serious.





    --------------------------------------------------------------------------------

    We have a record going back 2,000 years and when you plot it out, you can see the Medieval Warm Period (MWP) and the Little Ice Age (LIA), Thompson said. During the MWP, 700 to 1000 years ago, the climate warmed in some parts of the world. The MWP was followed by the LIA, a sudden onset of colder temperatures marked by advancing glaciers in Europe and North America .

    And in that same record, you can clearly see the 20th Century and the thing that stands out whether you look at individual cores or the composite of all seven is how unusually warm the last 50 years have been.

    There hasn't been anything in the record like it not even the MWP, Thompson said.

    The fact that the isotope values in the last 50 years have been so unusual means that things are dramatically changing. That's the real story here.

    While the isotope evidence is clear throughout all of the cores, Thompson says that the more dramatic evidence is the emergence of unfossilized wetland plants around the margin of the Quelccaya ice cap, uncovered as the ice retreated in recent years.

    First discovered in 2002, the researchers have since identified 28 separate sites near the margin of the ice cap where these ancient plants have been exposed. Carbon-dating revealed that the plants range in age from 5,000 to 6,500 years old.

    This means that the climate at the ice cap hasn't been warmer than it is today in the last 5,000 years or more, Thompson said. If it had been, then the plants would have decayed.

    The researchers say a major climate shift around 5,000 years ago in the tropics had to have cooled the region since the ice cap quickly expanded and covered the plants. The fact that they are now being exposed indicates that the opposite has occurred the region has warmed dramatically, causing the ice cap to quickly melt.

    The role of precipitation in the global retreat of alpine glaciers may have been clarified by this study. Some researchers, convinced that a reduction in local precipitation is causing their retreat, have been skeptical about the role of rising temperatures.

    While all the glaciers we have measured throughout the tropics are retreating, the local precipitation at all of these sites but one, has increased over the last century, Thompson said. That means that the retreat of the ice is driven mainly by rising temperatures.

    Changes in the oxygen isotope ratios over the past 100 years have also pointed to temperature, rather than precipitation, as the engine driving glacial retreat, he said.

    Tropical glaciers are the canaries in the coal mine' for our global climate system, he says, as they integrate and respond to most of the key climatological variables temperature, precipitation, cloudiness, humidity and radiation.

    Thompson said that the evidence arising from the tropics is particularly important. The uniformity of the climate in the tropics makes these kinds of records so critical since they tell us what is happening to global temperatures.

    What this is really telling us is that our climate system is sensitive, it can change abruptly due to either natural or to human forces, he said. If what happened 5,000 years ago were to happen today, it would have far-reaching social and economic implications for the entire planet.

    The take-home message is that global climate can change abruptly, and with 6.5 billion people inhabiting the planet, that's serious.

    Working along with Thompson and Mosley-Thompson on the project were Henry Brecher, Mary Davis, Ping-Nan Lin and Tracy Mashiotta, all with the Byrd Center; Blanca Leon of the University of Texas; Don Les of the University of Connecticut, and Keith Mountain of the University of Louisville.

    Support for the research came from the National Science Foundation, the National Oceanic and Atmospheric Administration and Ohio State.

    So I guess we should just allow industries to pollute are planet and let Bush lower the regulations for these industries! By the way 113 countries don't agree with you!

    New measurements show the ice in West Antarctica is thickening, reversing some earlier estimates that the sheet was melting.


    Jack Williams, USATODAY.com
    Looking across the ice from an ice-core drilling tower at the Siple Dome field camp in 1999. Scientists drilled into the ice here to study the history of the West Antarctic Ice Sheet.

    Scientists concerned about global warming have worried that higher temperatures could melt the massive ice sheet, causing a rise in sea levels worldwide.

    But new flow measurements for the Ross ice streams, using special satellite-based radars, indicate that movement of some of the ice streams has slowed or halted, allowing the ice to thicken, according to a paper in the Jan. 18 issue of the journal Science.

    If the thickening is not merely part of some short-term fluctuation, it represents a reversal of the long retreat of the ice, say researchers Ian Joughin of the California Institute of Technology and Slawek Tulaczyk of the University of California, Santa Cruz.

    Their finding comes less than a week after a separate paper in Nature reported that Antarctica's harsh desert valleys — long considered a bellwether for global climate change — have grown noticeably cooler since the mid-1980s.

    Air temperatures recorded continuously over a 14-year period ending in 1999 declined by about 1 degree Fahrenheit in the polar deserts and across the White Continent, that paper said.

    well there are people who deny the truth even when the FACTS show otherwise....

    There are people who deny the holocaust happened.

    There are people who deny that Global warming is real and man made

    there are people who deny that HIV causes AIDS

    They are ALL idiots and sadly you just placed yourself amoung them... congrats!
