***** 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 r*****e and its effects have ***** accumulating at a level th***** can be seen in the recent weather changes ***** 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 hurri*****es and flooding, including Hurricane Katrina in 2005 that devastated New Orleans; not to mention the one out of every five species facing extinction because ***** the ***** of greenhouse gases increasing over ***** last few *****.

The causes of this accelerated global warming of the earth's atmosphere are both simple and complex. The simple reason is that our *****use of 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 ***** the globe. That is ***** ***** cause. The *****, interrelated ***** have to do with our dependence on these fossil fuels and 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) ***** the special interest groups whose relatively short term economic goals are taking precedent over immediate and pressing ***** concerns. According to ***** majority of scientific experts on global warming, these complex fac*****rs, economic, national and social ***** impeding what should be an immediate, unified effort of nations to fashion solutions, ********** it is too late (Johansen, B.E., The Global Warming Desk Reference, 2).


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

The combustion of coal, oil and natural gas has been changing the atmospheric ***** ever since with ***** increases in carbon dioxide (CO*****), methane, nitrous oxides ***** other naturally occurring "trace *****" as well as synthetically produced chemicals *****d into the atmosphere. 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 to 1.5 gigatons. By 1960, the carbon ***** had passed 3.0 gigatons to more than 8.0 ***** by the ***** 19*****'s. This was a world increase of carbon dioxide 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 times over (Johansen, 3).

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