Global Warming - Carbon Emissions

For over two decades, the scientific community has been sounding the alarm of a man-made, global warming of our Earth's lower troposphere. This warming has been accelerating at an unprecedented r*****e 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 ***** 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 *****s.

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

The combustion of coal, oil and natural gas has been changing the atmospheric ***** ever since with the increases in carbon dioxide (CO2), methane, nitrous oxides and other naturally occurring "trace *****" as well as synthetically produced chemicals *****d ***** the atmosphere. During 1860, human created carbon emissions were at about one-tenth of a gig*****on (billion metric tons). This h*****d increased, between 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 ***** late 1980's. This was a world incre*****se of carbon dioxide ***** of 219 percent, or approximately a 7.3 percent increase, annually. Between 1850 and 2000, the human effluvia of CO2 emissions from fossil fuel combustion had increased fifty times over (Johansen, 3).

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