Effects Of Global Warming Essay

Catastrophic weather changes, the disappearance of islands, melting of Arctic ice, and a new ice age are all in store because of the carelessness of mankind’s tremendous amount of greenhouse gas emissions.“Human-generated greenhouse gas emissions have reversed a 2000-year cooling trend of the arctic” says environmental expert, James E. Hansen (Eilperin). There are those who believe that “the Earth’s peculiar wobble has set it on the Milankovich cycle which has warmed the planet due to its upheavals in our weather every 22,000, 41,000, and 100,000 years” (Bloom). The Earth has initiated a warming sequence as a result of human produced greenhouse gas, carbon dioxide, and methane that may lead to catastrophic weather conditions, the disappearance of Pacific islands, and a new ice age.
As early as the 1930s, scientists began to take notice of a warming trend that had increased average temperatures by several degrees since 1865 (ProQuest Staff). In 1938, an English engineer by the name of Guy Callendar stated that the greenhouse effect is the cause of the warming trend (ProQuest Staff). By 1956, weapons researcher Gilbert Plass realized that human activity could raise the average global temperature and pose a severe problem to future generations (ProQuest Staff). Geophysicists Maurice Ewing and William Donn agree with several journalists that ice sheets might disappear within the next few hundred years, bringing about a new ice age (ProQuest Staff). Their acknowledgement in 1956 marked the first time credible scientific experts had spoken out about the disastrous effects of climate change (ProQuest Staff).
Dr. Arthur Robinson, a professor of chemistry and cofounder of the Oregon Institute of Science and Medicine, disagrees that man-made greenhouse gases are to blame for global warming (Jasper). Robinson states that those who accuse mankind for global warming are altering or denying the facts in their favor (Jasper). With the support of numerous scientific experts giving credit to the fact that mankind has brought on global warming, assuming that the opposing side is lying is a bit far-fetched. Especially since the UN supports the fact that the earth is warming due to man-made greenhouse gas emissions. Agencies like the EPA (Environmental Protection Agency) and the IPCC (Intergovernmental Panel on Climate Change) agree “that ‘substantial increases’ will occur in the near future that could bring about potentially catastrophic changes” (ProQuest Staff). An assessment made by the IPCC also stated that “human activities are substantially increasing greenhouse gases in the atmosphere” (ProQuest Staff).
Greenhouse gas is responsible for the Antarctic ozone hole that is allowing more UV rays to shine down on the ice and melt it, which in turn reveals darker ocean that absorbs more sunlight, melting even more ice (Hansen). Man-made greenhouse gas emissions come mainly from the aluminum, magnesium, semiconductor, electrical...
