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

The causes of this accelerated ***** 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 ***** excess effluvia of CO2 into ***** atmosphere is affecting the ther*****atic temperature balance ***** the globe. That is ***** simple cause. The *****, interrelated ***** have to do with ***** dependence on these fossil ***** and the local, regional and national economic interests of a free-market economy that *****s 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, ***** complex factors, economic, national and social are 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).

CAUSES OF GLOBAL WARMING

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

The combustion of coal, oil and natural gas has been changing the atmospheric balance ever since with ***** increases in carbon dioxide (CO2), methane, nitrous oxides and other naturally occurr*****g "trace gases" as well as synthetically produced chemicals *****d into the *****. During 1860, human created carbon em*****sions were at about *****-tenth of a gig*****ton (billion metric tons). This had increased, between 1900 and 1940. to about 1.0 to 1.5 giga*****. By 1960, the carbon emissions had passed 3.0 gigatons to more than 8.0 gigatons by the late 1980'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 emissions from fossil fuel ***** had increased fifty times over (Johansen, 3).

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