Study Rules Out Global Warming Being a Natural Fluctuation With 99% Certainty 869

An anonymous reader writes "A study out of McGill University sought to examine historical temperature data going back 500 years in order to determine the likelihood that global warming was caused by natural fluctuations in the earth's climate. The study concluded there was less than a 1% chance the warming could be attributed to simple fluctuations. 'The climate reconstructions take into account a variety of gauges found in nature, such as tree rings, ice cores, and lake sediments. And the fluctuation-analysis techniques make it possible to understand the temperature variations over wide ranges of time scales. For the industrial era, Lovejoy's analysis uses carbon-dioxide from the burning of fossil fuels as a proxy for all man-made climate influences – a simplification justified by the tight relationship between global economic activity and the emission of greenhouse gases and particulate pollution, he says. ... His study [also] predicts, with 95% confidence, that a doubling of carbon-dioxide levels in the atmosphere would cause the climate to warm by between 2.5 and 4.2 degrees Celsius. That range is more precise than – but in line with — the IPCC's prediction that temperatures would rise by 1.5 to 4.5 degrees Celsius if CO2 concentrations double.'"

    All these so called scientists, spend 4 years in bachelors degree, 2 more for masters and four or five years to get a PhD. Work for about 80K a year median wage. They create these scare mongering stories to gin up grant money, totally untrustworthy.

    On the other hand the media consultants employed by the billionaire owners of coal, oil, petroleum companies and investments in forestry products have absolutely no conflict of interest and they speak the original unvarnished truth.

    I mean, who would you trust? Some one who is smart enough to make millions of dollars working for billionaires? Or the fools who spend so much of time studying and ending up working for a pittance? If these so called scientists are so smart why aren't they billionaires and millionaires? Shows who is smart and who you should listen to.
