    Barak=Total Disaster

    If you liked that story then you might love this one. The Australian scientist who wrote the carbon accounting model that measures Australia's compliance with the Kyoto Protocol, in the land use change and forestry sector says that since 1999 new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming. As Lord Keynes famously said, "When the facts change, I change my mind. What do you do, sir?"

    His main argument that is if carbon caused global warming you would find hot spots in the atmosphere over the tropics and the equator. Scientists around the world have searched for these hot spots without success, and Dr. Evans says that in light of this empirical evidence carbon emissions have to be rejected as the main cause of global warming and other sources considered. He laid it out clearly.

    1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.

    2. There is no evidence to support the idea that carbon emissions cause significant global warming. None. There is plenty of evidence that global warming has occurred, and theory suggests that carbon emissions should raise temperatures (though by how much is hotly disputed) but there are no observations by anyone that implicate carbon emissions as a significant cause of the recent global warming.

    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 (to the temperature of 1980). Land-based temperature readings are corrupted by the "urban heat island" effect: urban areas encroaching on thermometer stations warm the micro-climate around the thermometer, due to vegetation changes, concrete, cars, houses. Satellite data is the only temperature data we can trust, but it only goes back to 1979. NASA reports only land-based data, and reports a modest warming trend and recent cooling. The other three global temperature records use a mix of satellite and land measurements, or satellite only, and they all show no warming since 2001 and a recent cooling.

    4. The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect.

    No doubt Al Gore and other fear mongers will do one of two things, completely ignore the evidence and continue his rage about carbon emissions being the undoubted cause of global warming, or simply wet their pants and fade into a richly deserved oblivion.

    It is a really cool article. Here is the link.
