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 ***** 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 ***** the worst hurricanes 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 effects of greenhouse gases increasing over ***** last few *****.

The causes ***** this accelerated global warming of the earth's atmosphere are both simple and complex. The ***** reason is ***** our overuse ***** fossil fuels in industrial, affluent, and increasingly populated nations and the release of excess effluvia of CO2 into ***** atmosphere ***** affecting the ther*****atic temperature balance of the globe. That is ***** simple cause. The complex, interrelated ***** have to do with our dependence on these fossil ***** ***** the local, regional and national economic interests of a free-m*****rket economy that *****s tensions between developed nations (and between developed and underdeveloped nations) ***** ***** special interest groups whose relatively short term economic goals ***** taking precedent over immediate and pressing ***** concerns. According ***** the majority of ***** experts on global warming, these complex factors, *****, national and social are impeding what should be an *****, unified effort of ***** 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 fuels began during the Industrial age when economic ***** development brought greater financial pr*****it along ***** an increase in hum***** comfort and convenience.

The combustion of coal, oil and natural gas has been chang*****g the atmospheric balance ever since with the increases in carbon dioxide (CO*****), methane, nitrous oxides ***** other naturally occurr*****g "trace *****" as well as synthetically produced chemicals *****d into the atmosphere. During 1860, human created carbon emissions were at about *****-tenth of a gig*****on (billion metric tons). This had increased, between 1900 and 1940. to about 1.0 to 1.5 gigatons. By 1960, the carbon ***** ***** passed 3.0 gigatons to more than 8.0 ***** by ***** ***** 19*****'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 emissions from fossil fuel ***** had increased fifty times over (Johansen, 3).

***** *****es are a class of 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 w*****ld. Carbon dioxide (CO2) is the
