Global Warming A Deadly Threat For Human Life
1,510 wordsGlobal warming is one of the major environmental issues facing the world today. Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. An increase in the temperature of the Earths surface may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. One cause for Global Warming is called the Greenhouse Effect. The Greenhouse Effect results from a four step process. First, sunl...

Surface Waters Deep Water
646 wordsCold water discovered in the subtropical Atlantic was brought there by a current which had originated in the polar region; temperature measurements in the real ocean and computer models show there is a southward outflow of cold deep water from the Arctic throughout the Atlantic. This cold water is replaced by warm surface waters, which gradually give off their heat to the atmosphere as they flow northward towards Europe. This acts as a massive heating system for all the land downwind. The heat r...
