***** Warming - Carbon Emissions

For over two decades, the scientific community has been sounding the alarm of a m*****n*****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 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 hurri*****es and flooding, including Hurricane Katrina in 2005 that devastated New Orleans; not to mention the one out of every five species fac*****g extinction because of the ***** of greenhouse gases increasing over the last few decades.

The causes ***** this accelerated ***** ***** of the earth's atmosphere are both simple and complex. The ***** reason is that our *****use of fossil fuels in industrial, affluent, and increasingly populated nations ***** the release of excess effluvia of CO2 into earth's atmosphere ***** affecting the thermostatic temperature balance of the globe. That is the simple cause. The complex, interrelated ********** have to do with ***** dependence on *****se fossil fuels and the local, regional and national economic interests of a free-m*****rket economy that causes tensions between developed nations (and ***** developed and underdeveloped nations) ***** the special interest groups whose relatively short term economic goals are taking precedent over immediate and pressing global concerns. According to ***** majority of ***** experts on global warming, these ***** factors, economic, ***** 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).

CAUSES OF GLOBAL WARMING

The widespread use of fossil fuels began during the Industrial age when ***** ***** development brought greater financial profit along with an increase in hum***** 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 ***** o*****r naturally occurring "trace *****" as well as synthetically produced chemicals *****d ***** the *****. During 1860, human created carbon em*****sions were at about *****-tenth of a gigaton (billion metric tons). This had increased, between 1900 and 1940. to about 1.0 to 1.5 giga*****. By 1960, the carbon emissions ***** passed 3.0 gigatons to m*****e than 8.0 ***** by the ***** 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).

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