Global Warming - Carbon Emissions

For over two decades, the scientific community has been sounding the alarm of a m*****n-made, global warming of our Earth's lower troposphere. This warming has been accelerating at an unprecedented r*****e and its effects have been accumulating at a level that can be seen in the recent weather changes and natural catastrophes over the last decade. For examples: the most powerful El Nino ever on record; the hottest European summer in 2004 that killed over 26,000 people; some of the worst hurricanes ***** flooding, including Hurricane Katrina in 2005 that devastated New Orleans; not to mention ***** one out of *****y five species fac*****g extinction because of the ***** of greenhouse gases increasing over the last few **********.

The causes ***** this accelerated global ***** of the earth's atmosphere are both simple and complex. The ***** reason is ***** our overuse ***** fossil fuels in industrial, affluent, and increasingly populated nations ***** the release of excess effluvia of CO2 into ***** atmosphere ***** affecting the ther*****atic temperature balance ***** the globe. That is ***** simple cause. The *****, interrelated ***** have to do with ***** dependence on these fossil fuels and the local, regional and national economic interests of a free-market economy that *****s tensions between developed nations (and ***** developed and underdeveloped nations) and the special interest groups whose relatively short term economic goals are taking precedent over immediate and pressing global concerns. According to ***** majority of scientific experts on global warming, ***** complex factors, *****, nati*****al and social are impeding what should be an *****, unified effort of nations to fashion solutions, *****fore it is too late (Johansen, B.E., The Global Warming Desk Reference, 2).

CAUSES OF GLOBAL WARMING

The widespread use of fossil ***** began during the Industrial age when economic industrial development brought greater financial pr*****it along ***** an increase in hum***** comfort ***** convenience.

The combustion of coal, oil and natural gas has been changing the atmospheric balance ever since with ***** increases in carbon dioxide (CO*****), methane, nitrous oxides ***** other naturally occurr*****g "trace *****" as well as synthetically produced chemicals released ***** the *****. During 1860, human created carbon emissions were at about one-tenth of a gig*****ton (billion metric tons). This had increased, between 1900 and 1940. to about 1.0 ***** 1.5 giga*****. By 1960, the carbon ***** ***** passed 3.0 gigatons to more than 8.0 gigatons by ***** late 1980's. This was a world incre*****se of carbon ***** emissions of 219 percent, or approximately a 7.3 percent incre*****se, annually. Between 1850 ***** 2000, the human effluvia of CO2 ***** from fossil fuel ***** had increased fifty times over (Johansen, 3).

***** gases ***** a class of gases that trap heat near the Earth's surface. As they increase in the ***** atmosphere, ***** extra heat they trap creates global warming. This global ***** affects the Earth's climate system and can lead to weather changes through the world. Carbon dioxide (CO2) is the
