Global cooling....

Are we about to enter a period of global cooling???

A growing number of influential people in the developing world (this includes China, India, Indonesia, Vietnam, as well as Russia) are openly rejecting the idea that human activity has any measurable influence on the planetary climate or even that there is anything unusual or abnormal about the climate at present. Some of these people, joined by hundreds of scientists in the U.S. and Western Europe advance the idea that sunspot activity (which is cyclical) and the recently discovered (as recent as 1996) PDO (Pacific Decadal Oscillation: 20 to 30 year warming and cooling of the north-central Pacific Ocean) explain the cyclicality of global temperatures. According to those who hold this view, the planet has entered into a 30 year or so cooling period and carbon dioxide emissions even if they keep growing, cannot prevent this cooling.

In support they cite NASA’s recent study that the global oceans are cooling and expected to cool for several years. NASA is the leading proponent of man-made global warming. They also quote data from the new Jason oceanographic satellite that the PDO is entering a multi-year cooling period. Jason is run jointly by NASA and a French team. Other support for this idea that global cooling not warming, is the planetary future within anyone’s strategic planning horizon comes from experiments conducted by the Danish Space Research Institute, which links global climate behavior to variations in the magnetic wind of the sun, which is changeable, driven by sunspot cycles. Contrary to expectations, the current cycle (Cycle 24) is turning out to be very weak with negligible sunspot activity.

Two scientists at the National Solar Laboratory in Arizona project that sunspots will vanish by 2015, leading to a multi-decade down cycle in solar activity. The last time this happened was in 1645-1715 leading to bitterly cold winters and repeated crop failures (and to Napoleon’s defeat in Russia during the summer never came). Between January 2007 and May 2008 the earth cooled by as much as it had warmed in the past 100 years, according to a meteorologist at the University of Alabama. On May 19, 2008, the Oregon Institute of Science and Medicine released a petition signed by over 30,000 U.S. scientists rejecting claims that global warming is caused by human activity and condemning the Kyoto Protocol for its damage to humanity. This was well received the proponents of the cooling view and condemned by adherents of the warming view.
