This is a short PowerPoint that I made about Climate Change.

CLIMATE CHANGE
By: Jared Martin

2. • The graph above was taken from NASA.
• This graph represents the global surface
temperatures from 1880-today, and a prediction
for the years until 2020.
• According to NASA, 17 out of the 18 warmest
years have occurred since 2001 on the chart
above.
• It is extremely apparent that there is some sort
of warming trend going on.

3. • Due to the increasing
temperature that occur from
climate change, many forests
get hot and dry.
• As a result of this, many
wildfires will start to occur.
• This is especially harmful
towards humans. Trees
”inhale” carbon dioxide and
release beneficial chemicals
like oxygen.

4. • The photo above demonstrates the melting of glaciers due to climate
change.
• The melting of the glaciers will cause the overall sea level to rise. As a
result of this, many large cities like New York will experience extreme
flooding.
• According to the National Snow & Ice Data Center, areas that are
glacierized cover 5.8 million square miles.
• The NSIDC states that if all the ice on land melted, sea level would rise
around 230 feet worldwide.

5. • As you can see in the photo above,
climate change is literally destroying the
homes of many polar bear who rely on
the ice.
• With the ice melting, it is making it
harder and harder for the polar bears to
successfully hunt.
• Many polar bears swim for tens of miles
to search for any remaining ice.

6. • This devastating photo above shows the
melting of glaciers that took place over
the years at Glacier National Park.
• The melting of these glaciers are a
visual representation of climate change.
• Climate change and the warming trend
are ruining some of the world’s most
beautiful national parks.

7. Human Activities
• NASA claims that there is approximately a 95%
chance that climate is result to human activity
since the 20th century.
• A major example is the emissions that come from
your car or airplanes.
• According to the Union of Concerned Scientists,
emissions give off pollutants like; Nitrogen oxides,
carbon monoxide, sulfur dioxide, and greenhouses
gases like carbon dioxide.
• Other examples of human activity include leaving
the lights on when not using them, burning of
fossils fuels, deforestation and more.

8. The shocking graph above shows how high the
carbon dioxide levels are today, and how low they
were in the past. (Photo from NASA)
