Effects Of Global Warming Carbon Dioxide
1,531 wordsGlobal warming is the heating of the earth. This heating occurs because of the greenhouse effect. The greenhouse effect is when carbon dioxide and other gases (methane and nitrous oxide) trap energy from the sun in our atmosphere. Most of the energy we receive from the sun is absorbed by the surface of the earth. Some of the energy is reflected and would normally exit our atmosphere; however, carbon dioxide absorbs this energy and it remains in our atmosphere. The more carbon dioxide in the atmo...

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...
