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 rate and its effects have ***** accumulating at a level that 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 of the worst hurri*****es and flooding, including Hurricane Katrina in 2005 that devastated New Orleans; not to mention ***** one out of every five species facing extinction because ***** the ***** of greenhouse gases increasing over the last few **********.

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

CAUSES OF GLOBAL WARMING

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

The combustion of coal, oil and natural gas has been chang*****g the atmospheric balance ever since with ***** increases in carbon dioxide (CO2), methane, nitrous oxides and other naturally occurring "trace gases" 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 ***** by the late 19*****'s. This was a world incre*****se of carbon ***** ***** of 219 percent, or approximately a 7.3 percent incre*****se, annually. Between 1850 ***** 2000, the human effluvia of CO2 emissions from fossil fuel ***** 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, ***** extra heat they trap creates global *****. ***** global warming affects the Earth's climate system and can lead to weather changes through the w*****ld. Carbon dioxide (CO2) is *****
