The Effects Of Global Warming On The Earth

Presently, climate change is one of the largest threats to the Earth, and all recent research points to an anthropogenic cause. As humans burn fossil fuels, carbon dioxide and other greenhouse gases enter the atmosphere where they remain at unprecedented levels. As a result, greenhouse gases absorb infrared radiation emitted by the Earth and trap the radiation as heat, which should have left the atmosphere and entered outer space. This heat causes a gradual increase in the average temperature of the oceans and atmosphere, which scientists believe is permanently changing the climate of the Earth. Global warming is already greatly altering the surface of the planet, with many observable effects that include sea level rise, droughts, species loss, glacier melt, and ocean acidification (U.S. National Aeronautics and Space Administration 2016b). Recent studies also indicate that global warming is also responsible for altering the frequency and intensity of tropical cyclones. Observation has pointed towards warming ocean temperatures as responsible for fueling stronger hurricanes and the creation of fewer storms annually. This phenomenon is of concern due to the historically immense damage caused by high intensity tropical cyclones. A tropical cyclone is a low-pressure system that typically forms in the tropics, and is frequently accompanied by thunderstorms, heavy rain, and wind speeds as high as 190 miles per hour (Ahrens 2015). This type of storm system begins with a
