Global Warming Causes
Carbon dioxide is the by product of fuel such as gasoline, diesel,
kerosene and etc. It derives from many sources around the globe.
Combination of Carbon dioxide and water create a so called greenhouse
gas. It forms on the higher atmosphere where in the clouds form and
definitely creates global warming in the entire planet.
Here are some possible causes of global warming:
- The emissions of Carbon Dioxide from Power Plants – in U.S.
almost 40% of carbon dioxide and 93 % of coal emissions come from
burning of fossil fuels to generate electricity. Coal emits more or
less 2 times than the carbon when burned .It produces natural gas
that emits 50% carbon dioxide.
- Carbon Dioxide gives off from vehicles - vehicles are another
contributor to global warming. In U.S. alone 33% of carbon dioxide
emission comes from cars, minivan, jeeps and other utility vehicles.
It was found out that a car that gets 12 miles per gallon of fuel
will emit more or less 800 pounds of carbon dioxide within 500 miles
of travel within the city. So therefore in every gallon of fuel
consumed by every vehicle, 19.6 pounds of carbon dioxide was added
into the atmosphere.
- Carbon Dioxide from Airplanes and other aircraft- airplanes and
other aircraft contribute 3.5 % of global warming and has a tendency
to rise up to 15% in the near future according to UN
intergovernmental Panel of Climate Change.
- Carbon Dioxide from Building- construction of buildings and
building structures emits more or less 12% carbon dioxide.
• Methane - second to carbon dioxide, methane is another component
of greenhouse gas. It is 20 times or even higher affectivity in
trapping heat. It gain increase in its atmospheric levels of about
145% in the last century. The sources of methane are rice paddies,
fossil fuel production, bovine flatulence & bacteria in bogs. Rice
commonly planted and grown in flooded fields. In this situation,
organic matter in the soil will decompose and CH4 will contaminate
the air through the rice plants.
- Increase of Water vapor - water vapor definitely is the most
prevailing gas in the atmosphere. It enhances warming caused by
carbon dioxide, methane and many other gases. Two thirds of the heat
blocked by greenhouse gases was hold by water vapor and will cause
more warming around the globe. More clouds formation will takes
place due to this scenario and the heat will turn back out into
space.
- Nitrous oxide as one of the greenhouse gases - this kind of gas
is usually came from rainforest and oceans. It is called as
“laughing gas” which is sometimes used as anesthetics. Colorless and
non –flammable gas nitrous oxide was spread out into the atmosphere
by chemical reactions which probably involve sunlight.
- Deforestation - cutting and burning tress, in short destroying
rain forest can create a bulk of carbon dioxide in the atmosphere.
Deforestation according to NASA Web Site is the source of 20-25%
carbon emission to the atmosphere. The presence of rainforest could
absorb 2 billion tons of carbon every year and because the earth is
losing millions of acres tress in the forest hence the carbon will
directly spread over the atmosphere.
- City Gridlock – traffic in the city is one factor that causes
global warming. Study shows that drivers in Los Angeles and New York
City only loss 600 million gallons of gas every year just because of
traffic. These 600 million gallons will turn out to be 7.5 million
tons of carbon dioxide in two cities mentioned only.
- Carbon in Atmosphere and Ocean – According to Research
Information Office 750 billion tons of carbon is present in the
atmosphere and 1020 billion tons are dissolved by the surface layer
of water such as deep ocean likewise forest and soils which dissolve
610 billion and 1580 billion tons of carbon respectively.
- Permafrost - is a frozen soil with 2,200 feet depths
particularly in arctic and subarctic regions. Northern Hemisphere is
25 % permafrost which has 32 degrees Fahrenheit within two years.
There are hard permafrost that was built with buildings and houses
particularly in Alaska land surface, Canada, Scandinavia and
Siberia. The rising of temperatures will bring danger and
destruction to buildings, electric generating station, pipeline and
others. Furthermore due to instability of the ground erosion, affect
terrain, slopes, roads and foundations would likely damage.
- Tundra – is a called a “biome” which is describes as a region of
different vegetation. Animals and microorganism live vigorously in
unique kind of climate. According to research 50 billion tons of
carbon is frozen in tundra and turn out to be a source of carbon
dioxide today. University of California biologist “Walter Oechel,”
conducted studies on tundra’s carbon dioxide emissions who will
assumed by majority as a carbon sink but it was found out in this
study that it turn out to be a net emitter of carbon dioxide. Latest
study says that tundra is now dry and the historic carbon sink is no
longer present in site.
