*Global warming is a current issue in the media
with a wide variety of research supporting
different causes. I want to find the leading
reason our planet’s ice glaciers are melting.
*What is the main cause of global warming?
*The media highlight global warming to be a
problem although some research proves
otherwise. I would like to research both sides to
have a better understanding.
*I looked at information from Bob Corell’s Artic Climate Assessment and Paul Matewski research
*Then I looked at an alternate view from Rle Oldenburg from Naesaq Museum in Greenland and Dr. Soon an astrophysicist
*Also a New York Times article from Doha Talks about Global Warming and Climate Change
*The articles all had a good point of view but didn’t address the other side of the argument
*I expected to find a lot of research on this subject with multiple reasons on the cause of global warming
*I also expected some research to supported the idea that global warming does not exist.
*I hypotheses' that global warming is occurring and people are the main contributed to the problem because of all the pollution we release in the atmosphere.
*
*I conducted a content analysis because this
is a current issue with a lot of publicity. I
want to learn all the side of the argument
and if it is possible to change the melting.
*I researched several different sources to
gather data.
*
*Bob Corell, an American scientist, believes
people are the main contribution to the top of
the world melting
*Corell conducted a study called Artic Climate
Impact Assessment. In his results, he found the
temperatures in the artic is rising twice as fast
as the rest of the world
*The seas are rising and polar bears are getting
close to become extinction
*
*Corell’s research found when
green house gases are
released they are trapped
creating solar heat
*In 1992 Greenland had began
to melt then ten years later
much more ice has melted
*98% of the world’s mountain
glaciers are melting
*
*The amount of ice melting in the artic is equivalent to all
the ice in the alps (over 105 million acres of ice) in only
fifteen years
*He predicts sea levels all over the world will rise 3ft.
higher in 100 years
*When the ice melts it causes a chain effect. The snow
and ice melts then becoming dark water that produces
solar heat leading to more snow and ice melting
*
*Corell believes it is impossible to reverse global warming because so many green house gases have already been released that the temperature will rise no matter what we do differently
*He is certain global warming will increase the severity of our tropical storm such as hurricanes and cyclones in the pacific. Also global warming will lead to more storms
*
*Paul Mayewski, form USM, lead 25 expeditions collecting deep ice cores from glaciers in Greenland
*Ice catches everything in the air so the ice samples Mayewski gathered showed an atmospheric record that covers half of a million years
*The ice cores can explain the green house gas levels, whether it was stormy, and what the temperatures were over the years
*
*Matewski results told him human activity is responsible for
global warming
*The artic has not experienced CO2 levels like this in
thousands of years
*Something has changed to cause this melting and that is
burning of fossil fuels, releasing carbon dioxide, CO2 and
other green house gases
*
*Rle Oldenburg from Narsaq
Museum in Greenland believes the
climate warming is a natural
process that started in 200 BC
*When the Vikings first found
Greenland in the 10th century, the
land had no glaciers but instead
had green fields, trees, and open
waters
*The Vikings settled here because
it was a good place to farm, fish
and live. They created civilization
for a century until the climate
changed
*
*A few hundred years after the turn of the 11th century
the Vikings were wiped out. Greenland had began to
freeze over killing the crops and animals.
*Greenland was not the only part of the world get drop
in temperature. Rivers and canals in England and the
Netherlands also froze. People worried for their
safety.
*
*The climate is not constant but is always changing
*Dr. Soon, an astrophysicist, researched the eras of the
warming and cooling climate cycle
200BC- 600AD :Roman Warming
440- 900 :Dark Ages Cooling
900- 1300 :Medieval Warming
1300- 1850 :Little Ice Age (phase 1 and 2)
1850- present :Modern warming
*This research supports a natural climate cycle and not
an issue of global warming
*
*According to Doha Talks, Global warming is a rising
issues that needs to be addressed
*She believes this should be the most pressing issue for
world leaders
*The problems due to the use of too many green house
gasses mostly burning fossil fuels and forests
*
*In North America and other well developed countries, the rate of emission has dropped because of the week economies and awareness of the issue
*Many states in the U.S. have set renewable power programs that have played a large role in reducing emission
*Although emission had decrease in some of the advanced countries, the developing countries such as China and India continues to increase in emission
*
*Coal is the dirtiest and
most carbon fuel
* Emission rates increased
5% in the past year
*
*I found most researchers believe human activity is the
main cause of global warming.
*Each researcher had a different opinion on how to solve
the problem or if it even needed to be solved.
*The majority of the research I found supposed my
hypothesis with more detail.
*I believe my information would be more accurate if I
researched more people to have a wider range of data.
