Earth Science Air Mass The Texas A&M University (1996-2007) claims that the Continental Tropical air mass is probably what's developing in the state of Arizona. These represent dry, hot air masses being created over southwest U.S. and north Mexico. The air mass makes its way into the U.S. via western Texas, New Mexico, and Arizona, and typically moves in the east to northeast direction, carrying dry, hot air to the state of

Starting in the 1920's and 1930's, the lake's resorts were host to many Hollywood elite and prominent political figures. Author Peter Goin's book, Lake Tahoe (Arcadia Publishing, 2005) details this part of the Lake's history and talks about the steamers that frequently ran from point to point on the lake, whose whistles added to the trademark ethereal experience of the lake during that time period. Goin's book is heavy

This experiment showed that calcium chloride was the most effective substance tested in melting the ice, but only slightly compared to road salt and ammonium nitrate (3.5 minutes versus 4.25 minutes and 5 minutes, respectively). The results also showed that sand and cat litter required far longer (23 and 30 minutes, respectively) to complete the ice melting compared to 45 minutes for the ice that received no treatment at

James Hansen's role in the debate about climate change started after studying the atmosphere of Venus with NASA. Hansen went to the University of Iowa and studied under Professor Van Allan, who taught him about climates, which led to his work with NASA, but it was not until he began to realize that the climate of his own planet was undergoing a serious and dramatic change that he really entered

"We dare not tempt them with weakness. For only when our arms are sufficient beyond doubt can we be certain beyond doubt that they will never be employed. But neither can two great and powerful groups of nations take comfort from our present course. Both sides overburdened by the cost of modern weapons, both rightly alarmed by the steady spread of the deadly atom, yet both racing to alter

The picture to the left depicts the various elements that are responsible for thermoregulation in human skin. The illustrations shows the various layers of skin along with the veins, arteries and capillaries of the circulatory system that assist in insuring that the thermoregulatory system works properly. The sweat glands are responsible for selectively removing materials from the blood the sweat glands then concentrates or alters these toxins, and secretes them
