***** 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 rate and its effects have been 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 ***** one out of every five species fac*****g extinction because ***** the effects of greenhouse gases increasing over the last few decades.

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

The combustion of coal, oil and natural gas has ***** changing the atmospheric ***** ever since with ***** increases in carbon dioxide (CO2), methane, nitrous oxides ***** other naturally occurr*****g "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, between 1900 and 1940. to about 1.0 to 1.5 giga*****. By 1960, the carbon emissions ***** passed 3.0 gigatons to more than 8.0 gigatons by the late 19*****'s. This was a world incre*****se of carbon dioxide ***** of 219 percent, or approximately a 7.3 percent increase, annually. Between 1850 and 2000, the human effluvia of CO2 emissions from fossil fuel ***** had increased fifty times over (Johansen, 3).

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