IPCC Global Warming Fear Mongering

    Global warming fear mongers are heavily at work!
    Yesterday, Tony Barboza of the Los Angeles Times reviewed the latest preliminary report of the International Panel on Climate Change (IPCC).
    The IPCC says glaciers are shrinking and plants and animals have shifted their ranges in response to rising temperatures. As global warming continues through the 21st century, many species will face greater risk of extinction, marine life will shift toward the poles and seawater will grow more acidic. By 2100, hundreds of millions of people in coastal areas will be flooded or displaced by rising sea levels. The arid subtropics will have less fresh water. The global food supply of wheat, rice, corn and other major crops will drop 2% each decade. Extreme heat waves will be especially deadly in urban areas, associated with severe storms, flooding and drought.
    The IPCC says global surface temperature has risen about 1.5 degrees since 1880, and now predict that the planet will warm between 2.7 degrees and 8.1 degrees. Barboza does not mention whether these are degrees Centigrade or degrees Fahrenheit
    For a little converse data, Roy Spencer and John Christie measure global satellite temperatures monthly using satellite data. They use a base of 1981, 32 years ago. In 1997, 26 years ago, global temperature was 0.67°C above the base. In October of this year, the global temperature was 0.23° C above the base. In fact, the chart shows that there has been no increase in global warming in the last 26 years (since 1997). These are very different numbers from the 2.7° and 8.1°, predicted by the  IPCC for the future.
    More importantly, the IPCC makes its predictions on the basis that carbon dioxide is a super greenhouse gas, which inhibits release of heat from the earth to the stratosphere at night and leads to global warming. The IPCC claims that atmospheric carbon dioxide concentration has increased significantly over the past 20 years, which is true. However, there is no indication from the data that there is any connection between atmospheric carbon dioxide concentration and global warming.
    Is also interesting that all of the proponents of connecting atmospheric carbon dioxide concentration to global warming cannot give any reasonable mechanism by which carbon dioxide is said to perform its claimed disastrous effects.
