Who is responsible for global warming?
Global warming has been occurring for millions of years with natural temperature fluctuations; however the past half century has resulted in exponential growth in temperatures worldwide. “The hottest years on record have all occurred since 1990, and by the end of the 21th century the average U.S. temperatures could be up to 9 degrees higher”. Among other global issues rising ocean temperatures are great for your summer vacation on the beach; however the temperatures are causing algae and coral reefs to die effecting food chains. The resulting ripples in the food chain are catastrophic to food sources and economical system human’s use for their lively hood. Weather patterns are changing causing more droughts and floods, and hurricanes and tropical storms are stronger than ever because of the warmer oceans causing more destruction. Global warming is a natural phenomenon caused over millions of years, except global warming is now occurring faster than ever recorded. The increasing greenhouse emissions caused by the human race will continue to pollute the earth far too rapidly, and will have extreme long lasting consequences. According to the ; “The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) states: it is a greater than a 90 percent certainty that emissions of heat-trapping gases from human activities have caused increased global average temperatures since the mid-20th century”. The United States is the largest source of carbon dioxide pollution in the world producing 2.5 billion tons every year (2005). CO2 isn’t the only greenhouse gas responsible for heating up the planet by trapping the heat. Other gases include methane which traps more than 20 times the heat than CO2, and nitrous oxide at 300 times more heat, and chlorofluorocarbons has the heat-trapping potential thousands of more times greater than CO2 . Naturally the world’s oceans and plants absorb CO2 to keep the levels under...
