The Issue Of Global Warming

Decent Essays
Problems and History The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it. In 1988, the United Nation reported that carbon dioxide levels are nearing a dangerous level of interference with the climate system so they have established the Intergovernmental Panel on Climate Change (IPCC) (ProQuest). Greenhouse gas concentrations such as carbon dioxide, methane and nitrous oxide are continuing to rise during 2014 and it is reaching historic values (International).
