Global Warming By Lawrence Burnett

FAST FACTS In the last 1.6 million years there have been 63 alternations between warm and cold climates, and no indication that any of them were caused by changes in carbon dioxide levels. During the 20th century, the earth warmed 0.6 degree Celsius (1 degree Fahrenheit), but that warming has been wiped out in a single year with a drop of 0.63 degree C. (1.13 F.) in Over 80% of the 20th century's carbon dioxide increase occurred after 1940—but most of the century's temperature increase occurred before 1940!

FAST FACTS! Not only is carbon dioxide's total greenhouse effect puny, mankind's contribution to it is minuscule. The overwhelming majority (97%) of carbon dioxide in the earth's atmosphere comes from nature, not from man. Volcanoes, swamps, rice paddies, fallen leaves, and even insects and bacteria produce carbon dioxide, as well as methane. The global warming advocates make all sorts of false claims about dire consequences of global warming. They claim it will result in the spread of malaria, food shortages, more human deaths, more violent weather, and a loss of biological diversity through the extinction of species.

FAST FACTS! In the last 1.6 million years there have been 63 alternations between warm and cold climates, and no indication that any of them were caused by changes in carbon dioxide levels. The public has been led to believe that increased carbon dioxide from human activities is causing a greenhouse effect that is heating the planet. But carbon dioxide comprises only 0.035% of our atmosphere and is a very weak greenhouse gas. Water vapor is a strong greenhouse gas and accounts for at least 95% of any greenhouse effect. Carbon dioxide accounts for only about 3%, with the remainder due to methane and several other gases.

FAST FACTS! Agricultural productivity is also reduced by cold climate, not a warmer one. That's why Siberia and Alaska are not noted for agricultural abundance. A warmer climate would mean longer growing seasons and would make agriculture possible in areas where it isn't today. Our bodies require heat. We are warm-blooded and have no fur. We wear clothes, build homes, and heat them with fires, all as protection against the cold. Far more people move to Florida, California, or Arizona because of warm climate than move to Alaska, North Dakota, or Montana.
