Climate science seemed settled in the 1990s. The only theory around was that the increase in CO2 and other greenhouse gases was causing the increase in world temperatures. But then physicists got involved. My guess is that the average physicist has an IQ of somewhere between 150 and 200. The progress that they have been making is incredible.
If you have a scientific background and you still believe in man-made global warming, get out a cup of coffee, a cup of tea, or a glass of brandy, whatever helps you think best, and watch the following lecture from the Cern, one of Europe's most highly respected centers for scientific research:
This lecture by Jasper Kirkby reviews the recent research that physicists have been conducting into climate change. Physicists have discovered that changes in the rate of cosmic ray inflow cause climate change and that solar activity shields the earth from cosmic rays. They haven't completely worked out the mechanism yet, but they think it has to do with cosmic rays causing cloud formation and clouds reflecting sunlight back into space.
When Kirkby gets to the screen showing Galactic Modulation of Climate over the last 500 million years and the cosmic ray variation that explains it, take a close look at the line that plots CO2 over the same period. Note that that line doesn't correspond at all to the temperature periodicity evident in the temperature data. Also listen when Kirkby points out that CO2 concentrations used to be 10 times higher than they are today.
And don't miss the most chilling (literally) prediction of all based on a careful study of sunspot intensity. This prediction was originally submitted and rejected for publication in 2005 (Sunspots May Vanish by 2015), but has been coming true ever since. The earth appears to be headed toward a period of dramatic cooling, at present, due to reduced solar activity.
Meanwhile, clueless world leaders will be meeting at a UN Climate Change Conference in Copenhagen December 7-18 in an attempt to reduce carbon emissions in order to slow global warming.
