Global Warming(Real) And
Human Caused
Paul Wilkins
What Is Global Warming
 Global
Warming is nothing more than the
increase of Earth's average surface
temperature due to the effect of
greenhouse gases, such as carbon dioxide
emissions from burning fossil fuels or
from deforestation, which trap heat that
would otherwise escape from Earth and
this causes the called the Green House
effect
The Greenhouse Effect

When the suns radiations reach our atmosphere some
of it is reflected back into outer space and some of
that radiation passes through the atmosphere and is
absorbed by the earth and the heat is kept close to the
earth surface causing the earth to warming up. Then
the heat from the earth is radiated outward and
absorbed by the greenhouse gasses in the atmosphere.
This keeps the heat from disappearing into space and
keeps the earth warm enough just to sustain life
(Global Warming Fast Facts).
Human Caused

“The report, based on the work of some 2,500
scientists in more than 130 countries, concluded
that humans have caused all or most of the
current planetary warming(Global Warming Fast
Facts).”
Human Contributions to Global Warming
 Industrialization
-Burning of fossil fuels ie. Coal,Gas or
Oil.
 Deforestation
•
Deforestation

According to the Environmental Defense Fund (EDF), a
leading green group, 32 million acres of tropical rainforest
were cut down each year between 2000 and 2009—and the
pace of deforestation is only increasing. “Unless we
change the present system that rewards forest
destruction, forest clearing will put another 200 billion
tons of carbon into the atmosphere in coming decades…,”
says EDF
Various Problems

Weather (temperature raise)

Intense hurricane and floods

Wildfires

Wildlife, as many as a third of
the species known to science
may be at risk of extinction
A Possible Argument
We had record snows in the winter of 2009-2010 and also in 2010-2011.
The Counter Claim

Our local weather tells us nothing about another
continent, or the global average; it is only a local effect,
determined by short-term atmospheric and oceanographic conditions. In fact, warmer global temperatures
mean more moisture in the atmosphere, which increases
the intensity of normal winter snowstorms. In this
particular case, the climate change critics forget that the
early winter of November-December 2009 was actually
very mild and warm, and then only later in January and
February did it get cold and snow heavily.
Counter Claim Cont.

That warm spell in early winter helped bring more
moisture into the system, so that when cold weather
occurred, the snows were worse. In addition, the snows
were unusually heavy only in North America; the rest of
the world had different weather, and the global climate
was warmer than average. (How We Know Global Warming
is Real and Human Caused).”
What can we do as humans

Plant small Gardens/Trees.

Cut back on how we use electricity
-Turn off lights if not needed
-Light bulbs

Use city transit for transportation to cut on using automobiles so much (low
emission)
Green Peace
This organizations main campaign is to put a stop to global
warming. One solution Green Peace proposes is by having
renewable energy sources like wind, solar, and geothermal
can provide 96% of our electricity and 98% of our total
heating demand.
