Global Warming is shorthand for the climate changes that may result from excessive heat being trapped in the Earth’s atmosphere by so called green house gases. Global warming as defined in out test is “the gradual rise in world temperature, a suspected consequence of greenhouse gases trapping heat emitted from Earth that would otherwise escape in outer space” (380).
This climate change can be attributed to several different possibilities both natural and forced through human activity. “The general state of the Earth’s climate is controlled by the balance of energy the earth releases back to space”(Colls). One natural action, which can cause change, is the Earth’s shift in orbit rotating around the sun, this changes the amount of energy we receive from the sun. Other natural causes are within the oceans, atmosphere, ice sheets and volcanic eruptions to name a few. Such natural causes have created a series of ice ages on E
Over more recent years humans have caused many changes to the Earth which is a major cause for global warming. The burning of fossil fuels, deforestation, landfills, methane from rice cultivation and cattle raising are all examples of man-made greenhouse effect and global warming. The Greenhouse effect more specifically is the effect of “Warming of the Earth’s atmosphere caused by the presence of certain heat-trapping ‘greenhouse’ gases in the atmosphere”(Colls).
“The global north states are the principal sources of global carbon emissions, accounting for 73 percent of global carbon dioxide emissions”(Kegley & Wittkopf 383). We in the United States are not only the current hegemonic power but also the largest abuser of our atmosphere. This is due impart to our largely industrialized cities and over abundance of vehicles as well as inefficient power plants.
