Sun Is Real Culprit Responsible for Global Warming


Scientific Evidence Conclusively Shows that the Sun Plays a Far More Important Role in Causing Global Warming and Global Cooling than any Other Factor. In 1980, with the aid of NASA satellites, scientists proved that the sun's brightness or radiance varies in intensity. These variations occur in predictable cyclical patterns - hence, global warming and global cooling. This discovery is important because proponents of the Greenhouse Theory have always assumed that the sun's radiance was constant, thus, dismissing solar influence as playing a part in global warming.

There Is a Strong Correlation Between Solar Fluctuation and the Earth's Temperature. Simply put, when the sun gets dimmer, the earth gets cooler. When the sun gets brighter the earth gets hotter. In fact, half of the 1.5_F temperature increase since 1850 is directly attributable to the sun, not humans. Additionally, according to NASA scientists, only one-quarter of a degree can be ascribed to other causes, such as greenhouse gases, through which human activities can theoretically exert some influence.

Historical Proof that Changes in Solar Radiance Yields Changes in Earth's Temperature. During the Little Ice Age that lasted from 1650 to 1850, temperatures fell to as much as 2°F below today's temperature causing glaciers to advance, canals in Venice to freeze and major crop failures. Interestingly enough, this dramatic cooling happened during a period when the sun's radiance had fallen to exceptionally low levels. Scientists refer to this stage as the Maunder Minima; it is a cyclical phenomenom that typically appears for 70 years following 200-300 years of warming.

Global Cooling Due to Maunder Minimum. Since 8700 B.C. there have been at least ten major cold periods similar to the Little Ice Age. Nine of those ten cold spells coincided with Maunder Minima.

Evidence Shows that the Earth May Start Cooling Off. Dr. Sallie Baliunas, an astrophysicist with the Harvard-Smithsonian Center for Astrophysics and one of the nation's leading experts on global climate change, believes that there is a strong possibility that the Earth will start cooling off in the early part of the 21st century. It could already be happening. In the last fifty years, planetary temperature increased at a significantly lower rate than the previous 100 years. Further, NASA satellites show that global temperature has actually fallen by.04°F since 1979.
