Global warming is an increase in the earth's temperature caused by human activities that release greenhouse gases like carbon dioxide and methane into the atmosphere. These gases trap heat and cause the greenhouse effect, rising global temperatures. Problems occur when higher concentrations of greenhouse gases build up in the atmosphere from activities like burning fossil fuels and deforestation. Human health can be adversely affected by global warming through changes to climate that allow diseases to spread more easily.

1. Global Warming Essay
For decades societies have been concerned about climate change, and in recent years it has sparked
a debate as to whether the earth is warming due to causes by humans or through a natural
progression. There are scientists on both sides of the debate, but one thing that they can agree on is
that the earth is in fact warming. Studies have indicated a rise in the carbon dioxide levels (CO2) in
the earth's atmosphere that can be attributed to the what is known as the greenhouse affect (Simon,
Reece, Dickey, 2007). Natural occurring gases such as carbon dioxide, methane, and water vapor act
as source for trapping heat into the atmosphere, however CFC's or chlorofluorocarbons are man
made synthetics (Simon et al., 2007). These synthetic...show more content...
This puts a strain on aquatic life such as mollusks, coral, and plankton, which rely on a stable PH
level to build their exoskeletons (Simon et al., 2007). The increase in climate temperatures also
contributes to erratic weather patterns across globe. The Natural Resources Defense Council
(n.d.) has reported that due to the warming of the oceans there has been an increase in category 4
and 5 hurricanes over the last 35 years. In 2005 there were 27 named storms, which was the most
active season on record (NRDC, n.d.). This was also the year that hurricane Katrina made landfall
in New Orleans making it the deadliest and costliest hurricane in recorded history (NDRC, n.d.).
There has also been a higher level of droughts most notably between 1999 and 2002, which was the
most extensive in the last 40 years (NRDC, n.d.). The NRDC (n.d.) also claims that global warming
may have been the reason for the increased frequency in droughts over the last 40 years. With
droughts there can usually be expected wildfires, and in 2006 record levels were set in the amount
of fires reported and acreage lost at nearly10 million acres (NRDC n.d.). In stark contrast global
warming also contributes to increased rainfall totals in some areas. A study by the
Intergovernmental Panel on Climate Change observed that over the last 50 years an increase in
heavy rains has been a result of global climate change due to human

2. 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.
Now a days the Automobiles, heat from homes and businesses, and factories are responsible for
about 80% of today's carbon dioxide...show more content...
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

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.
