Most scientists believe that climate change is here and is human-induced, and that it will lead to more extreme weather patterns such as hurricanes and drought. Global warming means that the earth's overall air temp is rising. The one-two punch of carbon dioxide emissions and deforestation alter the global atmosphere. This is mainly from car exhaust, power plants and building emissions. When the earth's air temp rises even a few degrees, entire weather patterns change and get really extreme. This is already evident in the fierceness of hurricanes from Indonesia to New York City.
