Global Warming and its Effect on the World
Global warming is one of the most controversial topics being discussed by many
today. Global warming is a gradual increase in the overall temperature of the earth's
atmosphere. I have found there is a lot of research that explains how global warming is
causing great damage to the earth and its environment. Studies also show how life and
animals are also being affected by this. Global warming has emerged as one of the
biggest environmental issues in the last two decades and I feel that more people need
to take this more seriously and do things to lessen its effects.
Earth's climate has changed throughout history. In the last 650,000 years, there
have been seven cycles of glacial advance and retreat (climate.NASA.gov). This means
that glaciers grow and shrink. The glaciers shrink due to global warming and grow due
to precipitation. “In Montana's Glacier National Park the number of glaciers have
declined to fewer than 30 from more than 150 in 1910” (nationalgeographic.com). The
figure below shows how the mass of glaciers has been decreasing due to global
warming.

The ice from the glaciers is melting which causes the sea levels to increase. “Global sea
levels are rising 0.13 inches (3.2 millimeters) a year” (nationalgeographic.com). Not only
that, but the oceans are warming up due to the increase in CO2 gasses. On the top 700
meters of the ocean, about 2,300 feet shows that it has been warmed more than 0.4
degrees Fahrenheit since 1969. Thats 0.0078 degrees the ocean is rising per year. It
may not seem like a lot now, but in the far future that can cause great damage.

Some causes of global warming are since the 18th century we began to build
more factories, cars and power stations that have been slowly putting more and more
CO2 into the atmosphere. Every time we burn coal, gas, or oil we increase the amount
of gasses and add to global warming. In addition forests which absorb CO2 have been
cut down all over the world. With fewer trees more CO2 goes into the atmosphere. Also,
our world population has increased from one billion in 1800, to almost seven billion now.
More people equals more CO2. A warming earth disturbs weather, people, animals and
much more. Excessive emissions are leading to global warming. “If emission
entitlements could be clearly defined and all countries could emit subject only to their
quotas, each country’s emissions behaviour would change and the limitations on global
emissions would not be topped.” (Garnaut, Ross, et al)
Scientists are detecting a strong link between the planet's warming and its
weather patterns. The dangerous effects of heat waves including death occur as a
result of temperature and humidity. Higher temperatures also boosts evaporation which
dries out soil in the summer and causes droughts. In addition evaporation puts more
moisture into the atmosphere causing hurricanes. Lastly, the increase in snowfall may
also be linked to climate change because there is more moisture in the air because of
the increasing amount of evaporation due to the heat. (Climate.NASA.gov)
Exposure to health hazards related to climate change affects different people in
different communities to different degrees. With climate change the frequency, severity,
Trusty 4
and location are changing. Climate change can affect human health because the same
greenhouse emissions that cause global warming can lead to respiratory disease in
adults and children. “Air pollution kills and estimates 7 million people worldwide every
year” (un.org). By trapping heat in our planet carbon emissions also damage the human
body and mind in other ways, such as heat stroke.
Not only is global warming hurting the earth, it is hurting the animals also. It is
impacting polar bears in the Arctic and sea turtles in Africa (worldwildlife.org). In the
Artic it is having an even bigger effect becasue the heat is melting glaciers and effecting
precipitation patterns which are causing animals to have to go elsewhere to find food
(global warming effects). “Since 1906, the global average surface temperature has
increased by more than 1.6 degrees Fahrenheit (0.9 degrees Celsius)—even more in
sensitive polar regions” (nationalgeographic.com). Additionally, there has been a study
that indicates how “53% of monarch butterflies have decreased in Mexico due to global
warming”. The climate change has alos affected the turtles nesting sites by altering the
sand temperatures making it too hot to walk on. Because of the heat, it is impcacting teh
turtles mating and producing of eggs, which will ultimately result in a decrease of the
numbers of sea turtles (worldwildlife.org). Figure 2 below shows the picture of a polar
bear and explains the impact that global warming may have on these bears. “Climate
change is impacting flora and fauna across the Arctic. Although scientists don't know
specifically what killed this individual polar bear, experts warn that many of the bears
Trusty 5
are having trouble finding food as the sea ice they historically relied on thins and melts
earlier” (nationalgeographic.com).

The effects of global warming is being seen already in places such as Mozambi.
Over the past 20 years, Mozambi has an increase in droughts, flooding, and storms.
These increases have hurt the countries economy. Additionally, warmer temperatures,
changes in precipitation and more extreme weather events are projected for the
countries future. “These climate stresses may exacerbate both climate and nonclimate
stresses and affect development objectives, such as food security, natural resources
management, public health, and economic growth.” (Artur, Luís, and Dorothea Hilhorst).
Because of these extreme changes, the country is having to work at developing early
Trusty 6
warning systems to warn thier people and figuring out how to keep the economy strong
(Artur, Luís, and Dorothea Hilhorst).
Global warming has made such a big impact on society, there is even a movie
about it. This movie is called “Before the Flood” and it is a documentary that follows
actor Leonardo Dicaprios movement to five different continents to gian more of an
understanding of climate change, and its impact on the world. In this film Leonardo talks
with many different scientists and political leaders about this subject. “He also discovers
a calculated dis-information campaign orchestrated by powerful special interests
working to confuse the public about the urgency of the growing climate crisis”
(beforetheflood.com).
“Global warming can also have long term effects if it is not controlled. If it
continues at its current rate, Sea levels are expected to rise between 10 to 32 inches or
higher by the end of the century” (nationalgeographic.com). In addition, hurricanes and
other storms are expected to become strong and floods and droughts more frequent.
“Large parts of the U.S., for example, face a higher risk of decades-long
"megadroughts" by 2100” (nationalgeographic.com). In addition, if the warming is not
contained, less freshwater will be available since glaciers “store about three-quarters of
the world’s freshwater” (nationalgeographic.com). Lastly, because ecosystems will
continue to change some animals will move farther north and some animals, such as
polar bears, could become extinct (nationalgeographic.com).

So what is our world doing to help slow down global warming? The World Wide
Fund for Nature (WWF) was set up to urgently trying find ways to help. For example “in
October 2012, the WWF began a four year project to conserve a snow leopard habitat”
(worldwildlife.org). The organization promoted water security and helped communities
prepare for climate change impacts in Central Asia. Additionally, the WWF is asking for
cities to transition toward 100% renewable energy and implement easy measures to
improve air quality, protect water supplies and reduce urban flooding (worldwildlife.org).
In Paris, in response to global warming nearly “200 nations adopted a climate
agreement at the COP21 summit that will aim to limit our planets average global
temperature rise to less than 2 degrees celcius”. Also, at this same meeting in Paris, the
worlds leading scientific organizations also made statements publicly that endorses how
humans are most likely the cause of the past centurys global warming trends
(climate.nasa.gov).
What can we do as individuals to help with this crisis? We can do many things
such as “replace regular incandescent light bulbs with compact fluorescent bulbs, which
consume 70% less energy and lasts longer” (davidsuzuki.org). Additionally other ideas
include: driving less or carpooling, reducing, reusing and recycling, using solar energy,
using less hot water, turning off the lights, and even planting a tree. Eating is another
way to reduce climate change. How so, you might ask? “Eating more meat-free meals
and also growing your own food and not wasting it” (davidsuzuki.org) believe it or not is
Trusty 8
a way to help with global warming. There are many ways to help with global warming,
but these are a few that don’t take that are not to extreme and take little effort.
In the above paragraph, it is mentioned that reduce, reuse, recycle is a way to
help reduce global warming. Reducing is important because 230 million tons of garbage
is created in the U.S. each year (www.pbs.org). Reusing is important because one
ceramic coffee mug saves enough energy to produce 500 paper cups. Lastly, recycle is
important because there are 79 million tons of materials diverted from landfills and
incinerators. Lauren Singer, a New York resident has done this in a big way and she
managed to fit four years of trash she produced into a single mason jar
(nationalgeographic.com). This is an extreme example, but if we all put in just a little
effort it could make a big difference. In conclusion, there are things that we can all do to
help with this important cause, little or big.
Even with the evidence that is outlined above, there are some people that think
climate change is not real and is “fake science” (Trusty). Those who deny it exists have
a few key reasons for their disbelief. One key reason that some do not believe is
because they say scientists can not come to a mutual agreement on what causes global
warming. Some studies dispute that it occurs because of human intervention such as
pollution and claim that that statement that 97% of scientists agree on the cause of
global warming is inaccurate (procon.org). One report states that over 1,000 scientists
disagreed that humans are primarily responsible for global climate change. When
Trusty 9
looking at research from 11,944 studies it was found that only 3,974 of scientists had a
point of view on the causes of global warming. Of those that expressed a point of view
on the causes, “just 64 (1.6%) said humans are the main cause.” (procon.org).
Another key reason that some do not believe in global warming, is because the
average world temperature has remained consistent for several decades and small
fluctions are not significant. “Earth’s climate has always warmed and cooled, and the
20th century rise in global temperature is within the bounds of natural temperature
fluctuations over the past 3,000 years.”(procon.org). Even though the planet has
warmed 1-1.4 degrees, many say that this is soo tiny and is not a significant increase
and that it is not the first time we have seen the slight increases. “A study published in
Boreas found that summer temperatures during the Roman Empire and Medieval
periods were "consistently higher" than temperatures during the 20th century.”
(procon.org)
In conclusion, global warming is a major issue for the world and has many
negative side effects such as the impact on the earth, people, and animals around us.
As you can see from the studies I discussed above, I believe there is a tremendous
amount of evidence of global warming that should not be ignored. I feel that since global
warming is moving at slow rate people dont really give it that much attention. But we
should be trying to stop it as soon as we can before it gets too out of control. The
government and individuals are currently taking action to fight this challenge but it is
Trusty 10
going to take everyone working there hardest to beat it. There are many things called
out in this paper that we can all do to help with this very serious issue. “There is still
time to avoid the worst impacts of climate change, if we take strong action now”.
