Global Warming: Fiction Or Truth? Essay

1556 words - 6 pages

True or false; global warming is a catastrophic event that is occurring by natural and human means that is causing global temperature to rise and that can lead to many disasters? This has been an issue that hundreds and maybe thousands of scientists and citizens have debated about back and forth. The thought of global warming existing is a strong claim that many and most people have been backing up. Reliable sources have claims and evidence that is sufficient to prove global warming but other reliable sources also oppose the reality of global warming’s existence. If there is no action made towards the prevention of global warming, catastrophic changes may occur to our planet.
Most of the claims from global warming currently happening are currently taking impact. Claims like this include from sea level rising in many parts of the world and ecosystem changes. Ice is melting all over the world. The greatest toll is occurring at the Earth’s Poles. Places like Greenland and Alaska are also receiving a great effect from this. Animals in the Poles like Polar Bears and Penguin’s are suffering due to ice melting and temperatures getting too warm for their cold natured selves to handle.
While global warming may have current impacts on the world, it also can have future impacts. Sea levels are expected to rise between 7 to 23 inches by the end of this century and the continuation of melting at the poles can add about 4 to 8 inches more. If the global temperatures increases, hurricanes and other storms are likely to become stronger. Other weather catastrophes like floods and droughts will be more common. The availability of fresh water in the world will be decreased due to fresh water resources melting. Some animal species will move from their natural habitat and cause changes in ecosystems which can cause other animals to dominate and others to go extinct and so on. This can disrupt many ecosystems all over the world.
Global warming is caused by humans and natural sources in the world. Scientists have determined the fact that humane activities contribute to global warming by adding more and more amounts of greenhouse gases to the atmosphere. These greenhouse gases mostly carbon dioxide (CO²) accumulate in the atmosphere and trap heat that would normally exit into outer space. However scientists have determined that many greenhouse gases are naturally occurring. This is needed to create a greenhouse effect that keeps Earth warm enough to support life. The humane use of fossil fuels is the main source that adds excess greenhouse gases. Other causes of greenhouses emissions include things like driving cars and heating homes with oil or natural gas. With these causes carbon dioxide and other heat-trapping gases are released into the atmosphere. Deforestation is a huge source of greenhouse gases. With the decrease of trees, this means less carbon dioxide conversion to oxygen. During the last 150 years of the industrial age the atmospheric concentration...
