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 that can be seen in the recent weather changes and natural catastrophes ***** 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 ***** 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 ***** last few decades.

The causes ***** this accelerated ***** ***** of the earth's atmosphere are both simple and complex. The simple reason is that our *****use ***** fossil fuels in industrial, affluent, and increasingly populated nations ***** the release of excess effluvia of CO2 into ***** atmosphere is 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 fuels and the local, regional and national economic interests of a free-market economy that ********** tensions between developed nations (and between developed and underdeveloped nations) ***** the special interest groups whose relatively short term economic goals ***** taking precedent over immediate and pressing global concerns. According ***** the majority of ***** experts on global warming, ***** complex factors, economic, ***** and social are impeding what should be an *****, 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 ***** industrial development brought greater financial profit along ***** an increase in hum***** comfort and convenience.

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

***** *****es are a class ***** gases that trap heat near the ***** surface. As they increase in the Earth's *****, ***** 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
