Most climatologists agree that the earth’s temperature has increased about a degree over the last century. The debate is how much of it is due to mankind’s activity. Britain’s Channel 4 television has just produced “The Great Global Warming Swindle,” a documentary that devastates most of the claims made by the environmentalist movement. The scientists interviewed include top climatologists from MIT and other prestigious universities around the world. The documentary hasn’t aired in the U.S., but it’s available on the Internet.
Among the many findings that dispute environmentalists’ claims are: Manmade carbon dioxide emissions are roughly 5 percent of the total; the rest are from natural sources such as volcanoes, dying vegetation and animals. Annually, volcanoes alone produce more carbon dioxide than all of mankind’s activities. Oceans are responsible for most greenhouse gases. Contrary to environmentalists’ claims, the higher the Earth’s temperature, the higher the carbon dioxide levels. In other words, carbon dioxide levels are a product of climate change. Some of the documentary’s scientists argue that the greatest influence on the Earth’s temperature is our sun’s sunspot activity. The bottom line is, the bulk of scientific evidence shows that what we’ve been told by environmentalists is pure bunk.
Throughout the Earth’s billions of years there have been countless periods of global warming and cooling. In fact, in the year 1,000 A.D., a time when there were no SUVs, the Earth’s climate was much warmer than it is now. Most of this century’s warming occurred before 1940. For several decades after WWII, when there was massive worldwide industrialization, there was cooling.
