How Global Warming Endangers Polar Bears

Global Warming Global Warming
In recent years, global climate change due to global warming has been largely researched. The
paper, "Global Climate Change Triggered by Global Warming," offers compelling evidence from
various scientific papers that the process of Earth's climate undergoing significant change has
already begun and requires our attention due to the probability that human–generated greenhouse
gases are the primary cause. Major focal points are shifting towards determining the causes to
mitigate the effects rather than establishing the existence as sufficient amount of evidence has
proven that global warming is indisputable. During the final decade of the 20th century,
climatologists have concluded that the past millennium to be the warmest, especially in the year of
2005. Solutions towards the cause would require assistance from the population as a whole. An
example of a catastrophic climate change is a period known as the "Younger Dryas," an epoch in
time when the mean global surface temperature dropped drastically in a couple of decades and
lasted for one millennium. Although the circumstance of the Younger Dryas is quite different
compared to the present, it shows how cataclysmic a drastic climate change could enforce. Two
important or major definitions presented in the work are mean global surface temperature and
(global) climate. Mean global surface temperature is defined as "average of the air temperature
measured at the land surface and of the surface water temperature measured over large bodies of
water" (Jordan, 2006, p. 159). As for global climate, according to Jordan (2006), "the average of the
global weather...over a time interval appropriate to the rate at which the climate is changing" is the
best definition. These two terms appear frequently throughout, which shows the significance of
comprehending the meaning as it relates to the argument and explanation.
Arguments on the veritable source of action outlined in the paper are the sun, the long–term
quazi–periodic process, the urban heat–island effect, and the greenhouse effect. Most of the cases on
the natural force have been rejected or eradicated, such as the sun, due to contradicting evidence
found by further research on the hypotheses stated. The most

Global Warming
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural
processes caused by human, natural, and other gas emissions. (Melissa Phillips). This results in an
increased emission of greenhouse gases. (Caroline Quatman). Short–wave solar radiation sinks into
the Earth's atmosphere and warms its surface; while longwave infrared radiation emitted by earth's
surface is absorbed, and then re–emitted by trace gases. (Brent C. Willhoite)
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases.
Greenhouse gases can occur naturally as well as a result of human activities. (Melissa Phillips).

These gases trap heat and cause the greenhouse effect, rising global temperatures.(Heidi Sterrett).
Human activities add to the levels of these gasses, causing more problems. The burning of solid
waste, fossil fuels, and wood products are major causes. Automobiles, heat from homes and
businesses, and factories are responsible for about 80% of today's carbon dioxide emissions, 25% of
methane, and 20% of the nitrous oxide emissions. The increase in agriculture, deforestation, landfills,
industrial production, and mining contribute a significant share of emissions too The gases released
into the atmosphere are tracked by emission inventories. An emission inventory counts the amount of
air pollutants discharged into the atmosphere. These emission inventories are used by many
organizations. NASA and meteorologists also use them.(Heidi Sterrett).
The Centers for Disease Control have been involved in studying global warming's effect on human
health. Global warming is a danger to a human's health. Its affect on climate can adversely affect
humans. Plagues have been attributed to global warming. An increase in temperature can result in
a longer life cycle for diseases or the agents spreading them. Living in a warm area makes egg
production a quicker process. Global warming will lead to more precipitation, which enables
infectious diseases to be more easily contracted and spread.

Argumentative Essay On Global Warming
Global warming, we see it as sad polar bears hopelessly swimming for their lives in the ocean. It's
shown as rising sea levels that can washout entire cities. It even sometimes gets turned into politics
but scientifically, what is the definition of global warming? It is the heating up the of Earth, caused
by infrared radiation that gets stuck in our atmosphere because of the increase of CO2 put into the
atmosphere. Infrared radiation is electromagnetic radiation that cannot be seen by the human eye,
but we feel it as heat. Seems pretty logical doesn't it? To some it doesn't seem as reasonable. Some
believe global warming isn't a man made problem, but just a cycle of 'weather patterns'. For
example, our now president –Donald J. Trump– doesn't consider climate change to a threat to the
inhabitants of earth. Our president also said that global warming is a 'hoax'.
"Snowing in Texas and Louisiana, record setting freezing temperatures throughout the country and
beyond.
Global warming is an expensive hoax!"
–Donald J. Trump
This is what many people believe, and this tweet too seems pretty logical to a majority of people.
But in 2014 January 29th when Donald J. Trump posted this tweet, there was record setting freezing
temperatures happening nation and worldwide. But also 2014 was one of the top three hottest years
on record. Now that doesn't seem like a 'hoax'.
Humans don't like being wrong. It's embarrassing, uncomfortable to believe something and then be
confronted about it. So that's why there's still high percentage of people who don't believe in the
change in climate. People who work with oil companies don't want to acknowledge it because it
can ruin their business. Politicians ignore the problem because it costs money to fix our past
mistakes. That fear, people being scared, it makes us shut down. But we can try ignoring the
problem, but the thing about problems is, they can be ignored but they never truly disappear.
Weather may feel the same as every other year, but The whole world is heating up, including our
vast oceans.
Tropical hurricanes need to have surface water temperatures to be 26В°C or more for them to form.
As our oceans get hotter hurricanes are able to form farther out in the sea

Global Warming: A Human Cause? Essay
Global warming, just the thought of the words bring to mind scenes of melting ice, stranded polar
bears and dying plants. In today's society it seems humanity is always being blamed for the
tragedies that seem to go along with this catastrophe. However, research has proven that humans are
not the sole cause of global warming. In fact, some scientists say that the natural causes of global
warming far outweigh the human causes.
What exactly does global warming effect? The effects of global warming are spread across the
entire world and can be broken down into three main areas, the first of which is heat waves. Heat
waves are defined as periods of time lasting more than three days at which the average temperature

(47–48) This warming of the arctic also affects humans around the world not just the indigenous
people and animals. David Rind says "these increases in temperature around the arctic will most
certainly impact our weather here in the United States if we do not have those seemingly unneeded
outbreaks of arctic cold then we will not receive as much winter precipitation which will make it
hard for states like Kansas to produce their winter goods". (qtd in Johansen 286)
The final area that scientists break down the effects of global warming is wild storms. Global
warming is said to increase the amount of rain produced during thunderstorms which may in turn
cause floods. According to Robert Britt "as the climate warms up more water will fall in the form
of rain rather than snow which will cause the reservoirs to fill faster, this in turn will result in the
water runoff all into spring rather than being able to bring it out throughout the summer". In
addition to heavier rainfall, hurricanes and tropical storms are greatly affected by small increases
in the global temperature of the oceans. For example according to Dr. Kerry Emanuel "a 0.5 degree
Celsius increase in the oceans temperature can cause the power of hurricanes in that year to at least
double". With such extreme effects of global warming why is the human

Essay Title: Polar bears are endangered
Polar bears are one of the countless species who are endangered. They were one of the first
animals affected by global warming and their population is heavily decreasing. Around 1980, the
Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has
reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the
Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and
Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada,
since; Canada holds more than half the world's polar bear population. Other affected countries
include the U.S. (Alaska), Greenland,...show more content...
At the present rate of global warming most of the frozen portions of the Arctic may disappear by the
end of this century.
CONSEQUENCES OF THE ISSUE
There are so many consequences because of global warming and humans polluting. As a result of
global warming, the polar bear habitat is getting demolished. The warmer temperatures are
melting the ice in the Arctic and North Pole. Polar bears are travelling miles and miles to find ice.
Polar bears live, eat, and raise their cubs on Arctic ice, which is breaking up and melting at an
alarming rate. Year by year, this problem will get worse and worse. Humans and factories throw
away their waste in the ocean and it goes in the water the fish and animals drink. Polar bears eat
fish and they are affected by this polluted water as well. Hunters kill many animals including the
polar bears and it's decreasing their population. When polar bear population decreases, other
animal populations will rise and the animal chain will change. We should not let global warming
take over our species and destroy the animal chain. Polar bears are one of the many animals
affected and if there are too many animals affected, the whole animal chain will fall apart. Research
shows that, even if steps are taken to reduce emissions now, gases already in the atmosphere will
continue to heat up the earth for another 40 to 50 years. Scientific statistics indicate they may suffer
extinction by year 2100. We still have many years to make a

Global Warming Is A Threat Essay
Global warming has been a controversial issue since the first publication of global warming,
"Worlds in the Making," by Svante Arrhenius in 1896. This topic is discussed in multiple areas of
life, including politics, at the dinner table, and among scientists in a laboratory. The various
viewpoints of individuals usually lead to a heated discussion on global warming, and sometimes
ignites an intense argument. Through research and discussions with various people, I have come to
the belief that global warming is a real threat and needs to dealt with accordingly. Through act of
emitting extra carbon into the atmosphere, whether through burning fossil fuels or deforestation,
humans have inadvertently raised the average climate temperature over the last 200 years. Many
pieces of evidence support the claim that global warming is a significant issue today. The first key
piece of evidence I will discuss is the release of carbon into Earth's atmosphere. Since the
introduction of fossil fuels, which are the main source of energy on Earth, the average temperature
has increased slowly over the last 200 years, eventually amassing to a crucial level ("Global
Warming"). The second piece of evidence is the rapid speed of the melting of the polar ice caps.
Multiple satellite images have proven that the coasts of Antarctica are receding at a much faster pace
than in recent history (Conway). This retreat can cause many dire situations for our future
generations to come, including sea level to

Global Warming Argumentative Essay
Global Warming: Myth or Fact? The Global Warming theory has become increasingly popular over
the past few years. Citizens of the world are being encouraged to be more environmentally conscious
by others including politicians, celebrities, and world organizations. The problem with the theory
lies in the fact that it has become more and more controversial as it gains publicity and attention. The
basic concept behind this theory is that the earth was made with a balance of "greenhouse gasses".
These gasses are naturally occurring within the atmosphere and they essentially make the planet
habitable by keeping it warm. When the world became more industrialized, the amount of carbon
dioxide that was being emitted into the atmosphere...show more content...
The more people habituating the planet, the more potential there is for emission of greenhouse
gasses. In short, the basis of this argument other than years of documented research and scientific
discovery is what harm could we do by being more conservative in our use of energy and other
entities that produce more than their share of greenhouse gasses? The answer as it stands now is
none. The harmful effects of ignoring this crisis are all but proven fact. The problem that the pro–
global warming theorists have created is that of social standing and little else. While there may be
scientific backing to support some of the theory, the media presents the problem with great
sensationalism. Global warming and energy conservation has thus become a trend and losses some
of its validity through this. The scare tactics used by the media to "promote awareness" are just that,
a linguistic ploy to gain favor. "Awareness of this global threat reinforced public concern and
environmental problems and thereby provided environmental activists, scientists, and policy makers
with new momentum in their efforts to promote environmental protection." (McCright, 2000) This
statement draws line to the potential benefits that would be received if the pro–global warming
theorists were to draw enough attention to the issue. Driven by social empowerment and conviction
to environmental protection, these activists misrepresent the actual threat and paint it as being much

Climate Changes And Climate Change
The concept of climate change has been around for quite a while. The earliest mention of climate
change dates back to the 19th century. Swedish scientist, Svante Archenius was the first scientist to
study the effect of CO2 on climate. (Rodhe et al 1997)
The Intergovernmental Panel on Climate Change (IPCC) defines climate change as "A change in the
state of the climate that can be identified (e.g by using statistical tests) by changes in mean and/or
the variability of its properties and that persists for an extended period, typically, decades or longer.
Climate change may be due to natural internal processes or external forcings, or anthropogenic
changes in the composition of the atmosphere or in the landuse"
The UNFCC also defines climate change as "a change of climate which is attributed directly or
indirectly to human activity that alters the composition of the global atmosphere and which is in
addition to natural climate variability observed over time periods."
Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide,
Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere
make the earth habitable with respect to regulating the earth's temperature. However, an increase in
the concentration of these gases results in trapping energy in the atmosphere and this in turn
increases earth's temperature. "Global greenhouse gas emissions have grown since pre–industrial
times, with an increase of 70% between

Thesis Statement : Global Warming
Thesis Statement: Global warming is a growing concern of scientists and researchers who believe
that it is a serious problem for our planet. The concerns and research have also been questioned and
have even been called myths. Millions of people find themselves affected by these weather pattern
changes and are concerned for their futures. Activists on both sides of the argument are very
passionate and not afraid to attack each other in every way they can. There are many questions that
are still not answered, however, we continue to see drastic weather changes to Earth. We must go
beyond the arguments and learn as much as we can to stop what could possibly lead to the
destruction of our planet, our way of life and our future.
Global warming is concerned with an average increase in the temperature of the atmosphere and the
increase in the Earth 's surface temperature primarily due to the emission of greenhouse gases from
the burning of fossil fuels. As for the processes of global warming, they can occur from a variety of
causes. The causes include the things that are concerned with natural and human factors.
Some people believe that global warming is a myth or hoax. They believe that global warming is
being used to generate fear and panic and that those behind this movement are using it to control
people 's lives and for financial gain. "Within the community of scientists and others concerned about
anthropogenic climate change, those who are skeptics are more commonly termed

Global Warming and Climate Change Essay
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural
process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy
from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The
gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous
oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to
be trapped in the Earths lower atmosphere which causes global warming. If there weren't any
greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the
earth. Global warming can and...show more content...
Every time the temperature keeps rising, the more carbon dioxide will be released. When this
process gets going, it is very hard to keep in control. Methane is another greenhouse gas. Methane is
a greenhouse gas whose molecules absorb heat trying to escape to space. Natural sources include
wetlands, swamps and marshes, termites, and oceans. (Methane) Methane gases are released into the
atmosphere. Atmospheric methane has doubled since the Industrial Revolution and has "contributed
20 percent to the enhancement of the greenhouse effect, second only to carbon dioxide". (Methane)
A major effect of global warming is there will be higher temperatures and it will affect how the
water cycle works. Places on the earth will receive more rain than others. There will be a great
amount of evaporation going on from the rivers, lakes and oceans due to a increase in the
temperature. This could be a good thing for some people needing rain and a bad thing for other
people who get to much rain. While the temperature is on the rise there will be greater amount of
rains all over. In return with all of the rains this could help farmers. It would extend the growing
season for crops. This would greatly help out the farmers because they would be making more
money. While this is the positive side of the rain, this could also hurt the farmers. There are some
crops that out there that will die with to much rain. There

Essay on Global Warming
Global Warming
Our planet's atmosphere traps energy just like a greenhouse. Energy from the Sun can enter the
Earth's atmosphere, but not all of it can easily find its way out again.
What blocks the Sun's energy from escaping from the Earth? Unlike a greenhouse, the Earth does not
have a layer of glass over it! Instead, molecules in our atmosphere called greenhouse gasses absorb
the heat. Greenhouse gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide.
There may not be much of some of these gasses in our atmosphere, but they can have a big impact.
Each greenhouse gas molecule is made of three or more atoms that are bonded loosely together.
These molecules are able to...show more content...
About 30 gases produced by human activity have been identified as contributing to the greenhouse
effect. These are sometimes called greenhouse gases. The main ones are carbon dioxide, methane,
CFCs and nitrous oxide. Sunlight reaches the Earth's surface, is reflected off it, and is prevented
from escaping from the atmosphere by this layer of gases, which acts like glass in a greenhouse.
Up to a point, the greenhouse effect is a natural process, and naturally occuring carbon dioxide is not
dangerous. Without greenhouse gases, the average temperature of the Earth would be –19C , in
other words, too cold for us to live. However, the concentration of the greenhouse gases in the
atmosphere has changed dramatically: since the 18th century, carbon dioxide has increased by 30%.
There is disagreement among scientists about the seriousness of global warming. Most scientists
agree that the global temperature is rising. They do not agree on more specific elements of the
issue: How much will it warm up? What will happen if it does warm up? How far are humans
responsible? What should we do to stop it?
Scientists believe that if we go on producing gases at the rate we do now, it is likely that the Earth's
average temperature will rise by about 0.3 degrees C every ten years. This

The Impact of Global Warming on Oceans Essay
Water takes up a larger percentage of the surface of our Earth than does land. The earth's oceans are
vital aspects to our environment and it is necessary that we take care of them. On another note,
global warming is an issue that is having effects on almost all aspects of our environment. Global
warming itself means a gradual increase in the temperature of our Earth's atmosphere over large
periods of time. There is evidence that global warming has occurred in the atmosphere, however,
now we are beginning to see its effects in the world's oceans, as well. Though some may not see the
connection that it has with the oceans, it has had quite a profound effect on our Earth's oceans. As I
mentioned before, oceans are environments that must...show more content...
Now that we are aware that global warming is influencing our world's oceans, we must look at the
affects that it is having. I did not find any positive affects of global warming on the oceans. It is sad
to say, but I was left with only the negative. One of the effects that warmer temperatures have on the
oceans is that they disrupt the ocean circulation rate (Pearce, 1996). As I previously mentioned,
oceans must maintain all of its characteristics properly. Warmer temperatures in the atmosphere
affect circulation rates in the oceans. If circulation rates in the oceans are altered, then everything in
the oceanic environment becomes changed. The oceanic currents become affected, as well.
Global warming is also affecting the animals that live in our marine environments. These marine
mammals are accustomed to living in specific temperatures. They cannot survive in the water if the
temperature of the water changes dramatically. Thus, certain animals die as a result of the increase
in temperature of the oceans. Also, it is very difficult to receive data from something as large and
profound as our oceans. The various techniques that scientists use to receive data are not exactly
quiet experiments. The tools used to take ocean data are actually loud machines that are put into the
ocean. One might think that these loud machines would have no affect on animals because it is very
difficult to hear things under

Global Warming Essay
Global warming is the process in which the Earth's temperature starts increasing. This happens
because industry, fossil fuels, agricultural processes caused by human, natural, and other gas
emissions, this factors increase greenhouse gases, greenhouse gases are made up of carbon dioxide,
methane and nitrous oxide. The greenhouse gases stay in the atmosphere and prevent the suns
warming rays to leave the Earth. So the sun's warming rays stay inside the Earth increasing its
average temperature. Global warming isn't the end of the world, it's just a natural process in which
the Earth cleans or rinse organisms.

Lastly many bodies of water become polluted thanks to all the gasses in the atmosphere that mix
with the clouds and fall as acid rain polluting rivers, and lakes and killing many animals. All of
theses factors change our daily life and can ruin whole species, and all of this is because of
temperature changes.
Many scientific methods of controlling or lowering the Earth's temperature are being researched;
these can also be called geoengineering. Geoengineering is a method in which scientists can
change the levels of greenhouse gases directly or indirectly. Also there could be methods that
prevent greenhouse gasses to be emitted. There have never been any geoengineering solutions
done on a global scale since it has to be almost proof less. But there have been some ideas that are
being use on a small scale like the iron fertilization; this is a process in which iron is injected into
the oceans to speed up the reproduction of plankton which breath carbon dioxide and emit oxygen,
this is one solution that seems to have the least side effects thanks to the reason I just presented
and also due to that plankton are the base of many marine animals food chain. So this method is
being widely researched to see if it can be done on a global scale. Not only is lowering the levels of
gases in the air important, but also lowering the level of gases we emit, and there have been many
scientific breakthroughs like solar energy or cars that run

Persuasive Essay On Global Warming
In the world we live in, it seems like all of society has clouded judgement on just about everything.
You'll turn on the TV and see people go against all types of logical thought, and that can lead to
even your own judgement being shrouded in a cloud of confusion. One topic that leads in this
"social confusion" is global warming. While climatologists and many other well–versed people on
the matter argue for its reality, many have their hearts set on quite an opposite alternative. Our
world is plagued by the fake news brought about by these people, and the only way we can fix this
issue is to get past the lies and to focus on the solutions themselves.
Let's begin with the facts about global warming. Frankly, it's a problem, and a growing one at that.
It's a matter of extreme importance to many activists, and many of us have seen people speak up
about it across our media. This isn't just a media issue though, as many scientific organizations have
had their eyes on this issue. According to NASA, we've recently seen a global change in
temperature, our oceans warming, our ice sheets shrinking, our glaciers retreating, and our snow
cover virtually disappearing. Not only that, but our sea level has been increasing, the Arctic is
shrinking, and our oceans are becoming acidic. On top of that, the Intergovernmental Panel on
Climate Change itself stated that the "Scientific evidence for warming of the climate system is
unequivocal." Global warming is also responsible for the slow

How does the rising use of fossil fuels impact the earth? The simple answer is that the earth's
temperature rises, otherwise known as global warming. Global warming then devolves into climate
change. Global warming has been "proceeding at a rate that is unprecedented over decades to
millennia" ("Climate Change Evidence: How Do We Know?") because of the world's increasing
reliance on fossil fuels. World–wide natural disasters, such as Hurricane Harvey, may be correlated
to an increased risk in extreme weather events due to climate change. There has been efforts to
curb climate change, such as pieces of legislation like the Paris Climate Accord, but beliefs of
individual leaders such as Donald Trump, who "claims to think that links between carbon emissions
and climate change are 'a hoax'" (Steadman 19), has halted the fulfillment of such agreements
between states. If there is not effective efforts to slow the emission rate, the earth will face
devastating consequences. Therefore, the leaders of countries across the world must work together
to develop a solution to slow climate change, or else the future will be disastrous.
Global Warming and Climate Change
First, climate change and global warming must be defined and explained. According to Melissa
Denchek from the Natural Resources Defense Council, climate change is "a significant variation of
average weather conditions" (Denchek). The key factor is that the variation is a long–term trend,
and not just due to natural weather

Some people say global warming is caused by human activity, others say global warming doesn't
even exist. Some people claim that the climate is changing for the worse. They believe that humans
are the primary cause of these changes, especially the increase in temperature, caused by the burning
of fossil fuels. They believe that the temperature changes are causing glaciers to melt. They claim
that the melting of ice masses leads to a higher sea level and worsening conditions for Arctic
animals, as well as other negative effects on the environment. Others do not agree with this. They
say that the climate is not changing at all and that if it is, it is certainly not due to human behavior.
The term "global warming" refers to an abnormal, increasing average temperature of the planet. The
average temperature has fluctuated constantly throughout the whole time the Earth has existed, but
recently the climate has changed in ways it has not done earlier, as well as more rapidly than it
ever has before. The natural reasons for the climate to change are still occurring, but with an
addition of some thought to be caused by human activities. The primary cause behind the increasing
temperature is according to NASA large amount of greenhouse gases being released into the air
when fossil fuels are being burnt. The higher temperatures are said to cause for example melting
glaciers and increased coastal erosion. The melting of ice results in negative changes to the
ecosystem of the affected

Global Warming is due to the greenhouse effect. The greenhouse effect is a naturally occurring
process that aids in heating the Earth's surface and atmosphere. It results from the fact that certain
atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy
balance of the planet by being able to absorb longwave radiation from the Earth's surface. Without
the greenhouse effect, life on this planet would probably not exist as the average temperature of the
Earth would be a chilly –18 degrees Celsius, rather than the present 15 degrees Celsius.
As energy from the sun passes through the atmosphere a number of things take place. A portion of
the energy (26 %...show more content...
The now warmer atmospheric greenhouse gas molecules begin radiating longwave energy in all
directions. Over 90 % of this emission of longwave energy is directed back to the Earth's surface
where it once again is absorbed by the surface. The heating of the ground by the longwave radiation
causes the ground surface to once again radiate repeating the cycle described above, again and
again, until no more longwave is available for absorption.
The amount of heat energy added to the atmosphere by the greenhouse effect is controlled by the
concentration of greenhouse gases in the Earth's atmosphere. All of the major greenhouse gases have
increased in concentration since the beginning of the industrial revolution (about 1700 A.D.). As a
result of these higher concentrations, scientists predict that the greenhouse effect will be enhanced
and the Earth's climate will become warmer. Predicting the amount of warming is accomplished by
computer modeling. Computer models suggest that a doubling of the concentration of the main
greenhouse gas, carbon dioxide, may raise the average global temperature between 1 and 3 degrees
Celsius. However, the numeric equations of computer models do not accurately simulate the effects
of a number of possible negative feedbacks. For example, many of the models cannot properly
simulated the negative effects that increased cloud cover would have on

PERSUASIVE SPEECH ON GLOBAL WARMING by: Jennifer Zelmer
Introduction: We all know about global warming, but do we really care or try to do at least some
of the things that will help stop it or at least slow it down?
1) Over the last century our planets temp. has risen 1 degree. I know that doesn't sound like much
but it's been enough to melt a lot of the polar ice caps and glaciers. A) The hottest years ever
recorded were in the late 1990's and early 2000's. B) In 2007 there was a massive polar ice melt and
the amount of glaciers and sea ice has decreased quite a bit since the 70's. This has already caused
the sea levels to rise. C) The U.N. panel on climate change projects that by the end of this...show

C) And of course we can't forget the three R's. Reduce, Reuse, and Recycle. Only buy what you
need , ruse whatever you can, like containers and paper, and recycle what you cannot reuse. It's
really as simple as that.
4) Th extra heat our homes produce also adversely affects the planet. A) By sealing and insulating
our homes better we can help stop that and save money on our energy bills. B) Also instead of
turning up the heat when your cold, put on an extra layer of clothes. Again you'll be saving
energy and money. C) If at all possible, use solar energy. After all it's free, all you have to do is
buy the equipment. And you would be helping to ensure that our ancestors still have a planet to live
on. D) Finally, by turning off unused power sources such as tv's and computers, again you will be
helping the environment as well as saving money on energy bills.
Conclusion: If we all would do as many things that we possibly can to help reduce greenhouse
gasses in our atmosphere, we would all be doing a great thing by helping to ensure that our
grand–kids and theirs will still have this beautiful planet to live on and enjoy. Thank

Greenhouse Effect Essay
I have noticed that climate change has been a big issue this year. I think it's very important to talk
about Global warming and be aware of the causes of it. We all should want to take care of this
earth, because we are the ones living here. We should make people more aware of the greenhouse
effect and how it can affect us.
Consequently, in September of this year, Florida had some devastating hurricanes that wiped out
thousands of homes, businesses, and schools. According to Monmonier's book, "Coast lines: how
mapmakers frame the world and chart environmental change," He predicted that the sea levels
were rising at an unprecedented rate, causing flooding around the world, including the coast of
Florida and California (Monmonier pg. 131). The two main causes of global sea level rise are
thermal expansion of the warming of the oceans and the lack of land–based ice due to melting. Due to
global warming, our ice caps are melting, and our ocean temperatures are steadily increasing.
(Monmonier pg. 131). So how can we help?
Second is air pollution, this is one of the biggest problems we are having today. Air pollution is
caused by everything we do today. In the Earth's atmosphere, a process called the Greenhouse effect
occurs, it acts as a shield to trap in the heat from the sun, so it prevents the heat from going back into
space. The Greenhouse effect occurs in nature as carbon dioxide, methane, and nitrous oxide. People
say, "Without the greenhouse effect, the planet would be

summary on global warming, but in a few phrases. Introduction of the discussion: In this
discussion, there will be three pages elaborating on certain topics, which are sea levels rising, the
disappearance of land, rising temperatures rising and etc. These specific topics will be discussed
more efficiently in my three–page discussion and evaluated. Introduction...show more content...
We don't know yet what we're stepping up against. We first need to make sure everyone knows
what we're up against. But the worst is that since the temperature is rising, the ice will melt and

shows that the quantity of water in the sea is rising. It means the waters will invade any land on

like in the summer of 2003, when 70 000 people died in Europe. But it will take time for the ocean
to expand. Antarctica is melting, it's one of the causes of global warming. Trillions of gallons are
being released into the ocean. The sea levels are rising, its what's causing the temperatures to rise.
The higher the temperatures get, the more the sea levels rise. It will cause tsunamis, floods,
hurricanes and many other disasters will occur. Most of Antarctica's ice sheets are more than two
miles thick. It has happened before and it's happening again... It is happening right now! It is not
