***** 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 ***** been accelerating at an unprecedented rate and its effects have ***** accumulating at a level th***** can be seen in the recent wea*****r changes and natural catastrophes over the last decade. For examples: ***** most powerful El Nino ever on record; the hottest European summer in 2004 that killed over 26,000 people; some ***** the worst hurri*****es and flooding, including Hurricane Katrina in 2005 that devastated New Orleans; not to mention the one out of *****y five species facing extinction because of the ***** of greenhouse gases increasing over ***** last few decades.

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


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

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

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