Climate Changes And Climate Change
When you hear the words "climate change" what comes to mind? Probably weather and the
changes. Many of us watch the news or use an app on our cellphones/electronic devices to keep
an eye on the weather for the day, week, or even the month. But, there is actually a difference
between weather and climate. Weather is actually "the changes we see and feel outside from day
to day. It might rain one day and be sunny the next. Weather also changes from place to place"
(Dunbar, 2014). Whereas "climate is the usual weather of a place. Climate can be different for
different seasons. Different places can have different climates" (Dunbar, 2014). This paper will
focus on the ins and outs of climate change, specifically focusing on what climate change...show

But many climate scientists will tell you that this change in climate is due to humans and their
activities. It is said that humans release greenhouse gases and "if emissions continue unchecked,
they say the global warming could ultimately exceed 8 degrees Fahrenheit, which would transform
the planet and undermine its capacity to support a large human population" (Gillis, 2015). To
make it easier to understand, as sunlight reaches the Earth's surface there are two things that can
be done, one; it can either be reflected back into space or two, it can be absorbed by the Earth.
Once the Earth absorbs the sunlight, it then releases some energy back into the atmosphere as
infrared radiation, also known as heat. Then these greenhouse gases tend to act like a "blanket,"
therefore making the Earth warmer than it would be otherwise. This process is what we call the
"greenhouse effect." The reason scientists say that climate change is caused by humans is that it's
simple, humans drive, cook food, and even heat or cool their homes, which release gases such as,
carbon dioxide (CO2), methane (CH4 ), and water vapor (H2O).
According to a study in October 2015, "Earth had warmed by about 1.7 degrees Fahrenheit since
1880 when records begin at a global scale. Which includes the surface of the ocean. The warming
is greater over land and greater still in the Arctic and parts of Antarctica" (Gillis, 2015). Although
an increase of warmth of 1.7 degrees doesn't seem like it's a big deal,

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

Climate change is one of the most important challenges of humankind in this century. The ability to
adapt, mitigate and reduce carbon emissions will be decisive to preserve the world for future
generations. The last IPCC report has provided more evidence regarding the rise in temperature and
sea level. Apparently, additional 2В°C above the pre–industrial average temperature levels is
unavoidable, and it will continue at that level due the accumulation of gases in the atmosphere
(Solomon 2009). Climate change will affect people all around the world in different ways, though the
capacity to cope with it is different among regions and countries. The Latin America region is
notably susceptible to climate change, due its geographical position, population location and its
economy relying in natural resources (Vergara et. al. 2013a). The withdrawal of the coral biome,
glaciers melting, jungles & forest savannization and strongest climate events are only some of the
threats that will affect their inhabitants.
According to expert's estimations, the economic cost associated with climate change events in Latin
America with a temperature rise of 2В°C, is in the order of 85–110 billion per year by 2050
(Fernandes et. al. 2012, Dasgupta et. al. 2007, Vergara et. al. 2013 & Vergara et. al. 2007).
Economic injuries of this magnitude, can erode the development path of countries like Colombia
and Mexico . The restriction to natural resources access will undermine countriesВґ prospects for

Without this layer of gases the Earth would be too cold to be inhabited, perhaps 20 degrees cooler
than now. But, then amount of gases in this layer must remain constant. Even a slight increase could
have drastic results. Many people believe that a one degree increase in the temperature will not
cause much harm. The truth is with every degree of increase in temperature a 100 more wildlife
species are put in danger of extinction. Numerous experiments and studies prove that an increased
level of greenhouse gases, mainly carbon dioxide, is causing climate change and causing it fast.
2) Human Activities
A) Burning of fossil fuels–This is the most prominent and deadly source of climate change. Burning
of fossil fuels can release greenhouse gases ranging from carbon dioxide to ammonia. With massive
industrialization currently going on, the amount of fossil fuels burned is increasing. Transport and
heating are also major energy sources. Almost 7 giga tonnes of Carbon dioxide is emitted per year.
In the U.K three–fourths of energy produced comes from fossil fuels. Mineral fuels like petroleum
and coal are major sources of energy. In the last 150 years more than 45 Billion tonnes of carbon
dioxide has been emitted .The most problematic factor is that in the last decade; there has been no
slowdown in carbon emissions.
B) Poor use of land–Plants are the only natural purifiers of air and also the most abundant. But,

Climate Change and Its Impacts Essay
Our world is always changing, so is our climate. Some changes are apparent, others not so much.
Climate change is an important issue of concern in the twenty first century. Climate, if it changes at
all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly
all scientists predicted that it would take thousands of years for the planet to warm up due to
emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years,
things began to change. The rate and the amount of warming that is happening on this planet is
unprecedented. Wearth says, "People did not grasp the prodigious fact that both population and
industrialization were exploding in a pattern of exponential...show more content...
Global warming is a measure of climate change, and is a rise in the average global temperatures."
Climate change is caused by natural factors such as solar variability and human factors such as
greenhouse gases and ozone depletion. Evidence of climate change is growing but we are so
dependent on the use of fossil fuels in our everyday life such that it is only making the issue worse.
The heavy dependence of fossil fuels will continue to increase the carbon dioxide levels in the
atmosphere in a few decades. As the planet warms, there will be consequences. This research paper
will address the issue that climate change is occurring and its impact on temperature, oceans,
ecosystems, fresh water and the human population. As a human being on this planet the issue of
climate change bothers me because the rapid warming in the last few years is mostly due to
human–induced activities and we continue to warm the planet at this instant in time. The planet has
warmed in the last hundred years and it is also predicted that it will warm further in the next hundred
years. Although the increase in temperature may be small but they can lead to large and potentially
dangerous shifts in climate. Everyone's life is connected to climate change. If the climate changes,
the human society has to adapt to it by changing its designs, rules and infrastructure. Many places
have experienced climate change as the

Cause And Effect Essay On Climate Change
Climate change is a change in the usual weather that is found in a place. "A change in global or
regional climate patterns, in particular a change apparent from the mid to late 20th century
onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by
the use of fossil fuels (Oxforddictionaries.com, September 25, 2017)." Climate change has been an
ongoing controversial global issue about the effects that it has had on the Earth. Some people would
rather deal with climate change later, than now, claiming it is a problem for the distant future. But
the effects that scientists have predicted in the past are occurring now, such as loss of sea ice,
accelerated sea level rise, and longer, more intense heat waves. If we do not take action now, we
could be facing some serious issues in the future. "Scientists have high confidence that global
temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by
human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more
than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to
10 degrees Fahrenheit over the next century.
According to the IPCC, the extent of climate change effects on individual regions will vary over time
and with the ability of different societal and environmental systems to mitigate or adapt to change.
The IPCC predicts that increases in global mean temperature of less

Climate Change Impacts and Threats Essay
Global climate change, most commonly referred to as global warming, is a worldwide problem
facing our environment. Global climate change is simply a rise or fall in Earth's temperature over a
period of time. Although this problem has natural causes, the true detriments come from humans and
how we live day to day. Although many people have heard ofclimate change, there is not a big effort
to fix this problem or to understand it. The best way to rectify this change to the environment is to
help others recognize the causes of this problem and the effects they have on our planet. By
researching, one can determine their impact on the climate, as well as how to reduce this effect. To
understand how to fix global climate change, we must first...show more content...
It is also thought to be possible that the movement of continents changed the temperature of the land,
the air, and the oceans (encyclopedia of science). These environmental shifts have definitely played a
part in atmospheric changes. More recently, however, humans have had a much greater effect on the
earth. This all began in the late 18th century, when the Industrial Revolution was in bloom and there
was more need for factories and equipment. The smog and pollution coming from these buildings
was visible to all, and the damages were huge. This altered the composition of the earth's atmosphere
by creating much more carbon dioxide, and quickly had an effect on the global climate (epa.gov).
Even though each individual created very little carbon dioxide, when put together, the United States
created a lot. This is put best by Malcolm Gladwell, when he explains "we need to prepare
ourselves for the possibility that sometimes big changes follow from small events and that
sometimes these changes can happen very quickly" (11). To understand how much of an effect
humans have had, one must rely on the numbers and the experts. The industrial activities that our
modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per
million to 379 parts per million in the last 150 years. The [Intergovernmental] panel [on Climate
Change] also concluded there's a better than 90 percent probability that

Argumentative Essay On Climate Change
Over the years there has been a lot of controversy on if climate change is an issue that needs to be
discussed and solved. There is a constant debate among scientist on if human actions are contributing
the changing of earth's climates. Climate change is defined as the change in average weather
patterns for a specific region or Earth as a whole. This could include the change in an average
temperature for a city or the amount a rainfall it receives (Dunbar, 2015). The main difference
between weather and climate is the period of time specific patterns are recorded. Weather patterns
are looked at over a much shorter period of time, meaning that these patterns are going to be more
sporadic and change more frequently. Climate on the other had is recorded over a much longer
period of time and usually show less drastic changes in patterns when compared to weather. Some
people may argue that climate change is not an issue because Earth's temperature is always changing
do to natural effects. What people don't realize is that human activity has effected the rate that earth's
temperature is changing, and just the smallest changes can lead to drastic consequences (Dunbar,
2015). One of the main reasons that earth's temperatures are rising are due to greenhouse gases.
Greenhouse gases are created when humans burn fossil fuels such as coals, natural gases, and oils
to produce heat or electricity. These gases are then capable of trapping infrared radiation sent by the
sun. Once these

Synthesis Essay On Climate Change
It is terrible that climate change has affected every country. As a result, one key information that we
think will help us make a better analysis will be each country's progress in dealing with the issue.
This information can be found in recent news and articles that give detail reports on the topic. One
can also learn more from scientific documents written by ecologists that currently research on
climate change. Moreover, one can monitor the daily temperature of a specific season, summer for
instance, in the countries for a few years. From this point, one can calculate the average temperature
per summer and see which country had the most increase or decrease in terms of these average
temperatures. The country that experiences the least increase

Argumentative Essay On Climate Change
Climate change can be traced down to since the mid–1800s, when the industrial revolution first
started taking place all around the world. Lives of human and animal species have been negatively
affected since then, with events such as natural disasters, the melting of ice in polar regions, and
change in weather and living conditions. Climate change in polar regions, in particular, has faced
the most damage compared to any other region because of its location in regard to the sun. Climate
change holds many different views and opinions about the effects, and even the existence itself, but
evidence is clear and unmistakable in global ramifications and local impact in polar regions.
"...Climate change [is] the 'greatest hoax ever perpetrated on the American people'", skeptics like
Senator Inhofe of Oklahoma like to say. Climate change is change in climate patterns due to an
increase in carbon dioxide and other greenhouse gases produced by certain human activity.
According to the National Snow and Ice Data Center, data taken by satellite has shown that the
Arctic cover has decreased by 30% over the past 30 years, and this change, which also include
change in sea ice and permafrost, in artic weather and climate is caused by humans. Although
numerous scientists have confirmed the legitimacy of climate change, there are different views on
whether climate change is real or not. Government officials like Senator Jim Inhofe of Oklahoma or
Senator Marco Rubio of Florida have explicitly stated that they do not believe climate change is
neither real, nor caused by humans (Tom McCarthy, 2014). On the other hand, mainstream media
and other media outlets, such as The Independent and The Economist, have reported their findings
of climate change and its legitimacy. The Independent (Conner, S. 2011) reported that records of
these changes were taken by military submarines, land measurements, and satellite data to prove ice
in polar regions are melting faster and faster. Satellites have tracked sea ice since the 1970s and by
nuclear submarines since the Cold War,
according to Peter Wadhams of Cambridge University and it was predicted that by September
2015, there would be no more sea ice. (Conner, S. 2011). Luckily, sea ice has not

This is not just because more economically developed nations have more carbon emission and
should have more responsibility; it is also about the future of these developed nations. Even if the
more economically developed nations do not help the less economically developed nations, the
effects of climate change will still affect the developed nations. More importantly, the less
economically developed nations' economic impact to the world from climate change will have some
amount of impacts to the more economically developed nations. So by taking the lead and help the
less economically developed nations to survive in climate change, more economically developed
nations can economically benefits
Overall, all the nations are contributing to climate change and all of them should have a
responsibility. In contrast, more economically developed nations contributes more to climate change
than less economically developed nations does but unfortunately less economically developed
nations are facing more problems from the climate change. Therefore more economically developed
nations should take more responsibility so that the less economically developed nations will not
suffer as bad and should also take the lead, helping the all other nations in the world to survive in

Reflective Essay On Climate Change
Climate change is an unpredictable change in weather among the countries and states that make
up parts of the world. Despite the tragedies of Hurricane Sandy, the ongoing California Wildfires,
and the three hurricanes that divested Texas, Florida, and Puerto Rico, I believe those powerful
climate events is the truly beginning of what the world is in store for. I feel like in a way not
only is mother nature sending signals, but so is God. The last natural disaster North, South, and
Central America are waiting for is the Tsunami that will wash away our humanity. However, one
object that will vanish our entire existence before God does is the bomb Koreans will soon erupt
on our soil. To fight for our lives and planet, as humans we should take better care of our
environment before it all comes crashing down like a domino effect.
Climate change has affected social classes by targeting low–income communities in pollution
industries around the areas just out of convenience. Communities of both colored and low–incomed

Importance Of Climate Change Essay
Climate change is one of the biggest problems the whole world is collectively facing. Even though
climate change is partially caused by the natural cycles of Earth, humans I think are still a major part
of it and I think that we can do more to protect the environment that we live in. Climate change
happens when temperatures increase dramatically. When climate change causes temperature rises
many environmental problems can occur here on earth . Temperatures rising can result in more
floods, droughts, or flooding rain, as well as more frequent and severe heat waves which can cause
wildfires. Oceans and the Antarctic Ice Glaciers have also experienced changes in oceans that are
rising temperatures and are becoming more acidic. The Antarctic ice glaciers are melting and sea
levels are rising destroying many habitats along the ice glaciers such as penguins and polar bears. As
these changes frequently occur in future decades, they will likely present challenges to our society
and environment.
Greenhouse gases ,such as carbon dioxide, is absorb and emits heat into the earths atmosphere,
keeping the Earth warm enough to support life. However, human activities, such as burning fossil
fuels, are adding large amounts of greenhouse gases to the atmosphere. Earth must get rid of energy
at the same rate it receives energy. More greenhouse gases means that more heat is being held in the
atmosphere, which makes the temperatures higher. All the greenhouse gases people have added to the

Heat takes a lot more energy to reduce the temperature while the cold is easier to adjust to. Another
collateral affect the climate change would have is poor air quality. With pollution from power and
emissions from cars and power plants causes things like smog and bad air for us to breath in our
atmosphere. http://climate.nasa.gov/causes/ Warmer temperatures and higher concentrations of
carbon dioxide in the atmosphere stimulate some plants to grow faster, mature earlier, or produce
more potent allergens. Allergy–related diseases are among the most common and chronic illnesses
that can lead to lower productivity. Young children, the elderly, and those who are already ill are less
able to withstand high temperatures and poor air quality. Temperature extremes and smog hit people
with heart and respiratory diseases, including asthma, particularly hard.
"Climate change has a variety of reasons why the earth is absorbing so much heat one of those
reasons are from when sunlight reaches Earth's surface, it can either be reflected back into space
or absorbed by Earth. "Once absorbed, the planet releases some of the energy back into the

Climate change has been discussed a plethora of times in the science community. Only a small
number of scientists believe that climate change is not happening. Most scientists today agree that
climate change is indeed happening and its causing extreme damage to the planet. What is majorly
causing climate change is the burning of fossil fuels. The gasses released are affecting the
atmosphere creating a greenhouse like effect on the earth which makes the temperature of the earth

Part of the conclusion of the article "Climate change: evidence of human causes and arguments for
emissions reduction", written by Baum, Misra, and Karmosky states, "Climate change is a complex
and important issue. The study of climate change spans many academic disciplines across the natural
and social sciences, humanities, and engineering. Existing research finds that there is very strong
evidence that the climate is changing, that these changes are driven primarily by human activity, and
that the changes will have very large impact on natural and social systems." (12)
There are many effects of climate change that will affect many multicellular organisms. Polar
Bears being one of those organisms is already becoming extinct because of climate change. Due
to the rising temperatures of the earth's surface, the sea ice has been melting. Sea ice happens to
be a crucial factor for Polar Bears. The article "Climate change threatens polar bear populations: a
stochastic demographic analysis" written by Hunter, Caswell, Runge, Regehr, Amstrup, and
Strirling, states that sea ice has been decreasing, "The extent of perennial sea ice in the Arctic has
been declining since 1979 at an average rate of 11.3% per decade (Stroeve et al. 2007, Perovich and

Informative Essay On Climate Change
The earth is a beautiful and extraordinary planet, but are we treating it right? For the past 20 decades,
temperatures have been rising along with hundreds of factors contributing to it. Climate change
concerns the public as they wonder if its occurring, how much has occurred in the modern era, what
has caused it, what the effects will be if we don't do anything about it and much more. Many people
and scientist agree that mankind is the number one cause of climate change. Humans have
influenced this by greenhouse gases, methane nitrous oxide.
Scientific evidence suggests that human activity like agriculture, urbanization and industrialization
have influenced climate change. Clearing land and building cities up for agriculture results in
changing the climate. This is because the population is increasing rapidly and the demand to use
fossil fuels in our everyday life is also increasing. Increasing use for fossil fuels, industrialization and
deforestation has a huge impact on the climate. Enhanced greenhouse gases are an increase in
natural greenhouse gases impacted by mankind. The major cause of greenhouse gases is the increase
in carbon dioxide, methane and nitrous oxide being released in the atmosphere. If greenhouse gases
continue to be produced at the same rate as it did in 2000, then there will be a 0.1–degree change in
temperature per decade. This isn't likely to happen though because of the dramatic need for fossil fuel

Persuasive Essay On Climate Change
Climate Change
Not everyone in the world has noticed that the climate has changed throughout the years. The
negativity of climate alternation comes from pollution, weather, and temperature changes, which
will endanger the earth. However, it's possible that some people in the world are willing to help;
people are trying to decrease the chances of climate modification from raising. Even though climate
change is very bad for the earth and toward humans, no one can put an end to this problem due to
several causes which will affect us. Three different outcomes that surround the topic climate change
comes from our human activities, environment changes, and human health issues. These are the
reasons why it causes climate changes to create negative effects on the earth.
Greenhouse gases are the reason why climate change has affected the environment for many years.
Changes that can happen in the environment could be how cold is the temperature today, how much
sunlight is being produced during the day or is there enough clean water. The environment gets
affected when "the atmosphere traps the heat radiate into the Earth toward space" (NASA 1). When
that happens the environment will change the "impacts on human systems which involve food
production, local livelihoods, and health" issues (Environment and Climate Change Canada).
Different type of effects that can happen to the earth could be "sea levels, droughts, floods and
other extreme weathers, climate change ecosystem and extinction threats" (Greenpeace
International 1). Other living things such as insect, bird, or plant will be extinct or will move to
different places in the world and this will affect human health issues (National Geographic 1).
These issues will cause trouble to the earth's environment, and it's not possible to know when the
problems will turn more worst. Ice melting from the Arctic has increased, due to climate change and
it will harm the polar bears, seals, and penguins (National Geographic 1). My grandmother has
grown vegetables in her backyard, and as the climate changes, this affects the growing process of the
food. In the summer when I go outside the temperature has increased from the radiated of the sun

Human activities

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
