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 ***** been accelerating at an unprecedented rate and its effects have been accumulating at a level th***** can be seen in the recent wea*****r changes ***** 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 and flooding, including Hurricane Katrina in 2005 that devastated New Orleans; not to mention ***** one out of *****y five species fac*****g extinction because ***** the effects 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 simple reason is that our overuse of fossil fuels in industrial, affluent, and increasingly populated nations and the release ***** excess effluvia of CO2 into ***** atmosphere ***** affecting the thermostatic temperature balance ***** the globe. That is the ***** cause. The *****, interrelated causes have to do with our dependence on these fossil ***** ***** the local, regional and national economic interests of a free-market economy that ***** tensions between developed nations (and ***** developed and underdeveloped nations) and 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, *****, ***** and social are impeding what should be an *****, unified effort of ***** to fashi***** solutions, before it is too late (Johansen, B.E., The Global Warming Desk Reference, 2).


The widespread use of fossil fuels began during the Industrial age when economic industrial 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 ***** ever since with ***** increases in carbon dioxide (CO2), methane, nitrous oxides and other naturally occurring "trace *****" as well as synthetically produced chemicals released ***** the *****. During 1860, human created carbon em*****sions were at about *****-tenth of a gig*****on (billion metric tons). This had increased, between 1900 and 1940. to about 1.0 ***** 1.5 gigatons. By 1960, the carbon emissions ***** passed 3.0 gigatons to more than 8.0 ***** by the late 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 and 2000, the human effluvia of CO2 ***** from fossil fuel combustion had increased fifty times over (Johansen, 3).

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