1. Global Warming PowerPoint
Presentation
Reed Sarosiek
Hr. 1

2. Overview
• For this project we were assigned to
create a PowerPoint presentation on the
alarmist and the skeptics views on global
warming then express our own views on
global warming by using facts to back our
beliefs.

3. What is Global Warming?
• Global Warming is the theory that we as
humans are increasing greenhouse gases
(the think layer of gases that catches the
sun’s rays and heats the earth) through
industrialization causing more gases and
increasing the amount of sunlight that gets
caught and heats the Earth.

4. Alarmist Viewpoint
• The alarmist viewpoint is that global
warming and pollution from CO2
emissions are adding to greenhouse
gases so significantly that the Earth is
warming up and will continue to warm.

5. Why is this warming bad?!
• Alarmist believe that this increase in
temperature will eventually cause the
melting of the ice caps. This melting could
increase the oceans height by up to 2 feet
in only one century! This would mean
many heavily populated costal cities would
flood causing millions maybe billions of
dollars and damage and the potential loss
of life in these cities.

6. Other Effects from Global Warming
• The alarmist believe that there are also
other effects to global warming such as
natural disasters have been increasing,
disease have been spreading more
rapidly, and animals have been found
migrating towards the poles due to the
increase in heat.

7. Facts to Back the Alarmist View
• The number of category 4 and 5 hurricanes have
almost doubled in the last 30 years.
• Malaria has spread to higher altitudes in places
like the Columbian Andes, 7,000 feet above sea
level.
• The flow of ice from glaciers in Greenland has
more than doubled in the past decade.
• At least 279 species of plants and animals are
already responding to global warming, moving
closer to the poles.

8. Future Effects of Alarmist’s Global
Warming
• Deaths from global warming will double in just
25 years, to 300,000 people a year.
• Global sea levels could rise by more than 20 feet
with the loss of shelf ice in Greenland and
Antarctica, devastating costal areas worldwide.
• Heat waves will be more frequent and intense.
• Droughts and wildfires will occur more often.
• The Arctic Ocean could be ice free by 2050.
• More than a million species could be driven to
extinction by 2050.

9. Alarmist’s Solution
• By doing things like using compact
fluorescent bulbs, inflating your tires
properly, use recycled products, drive a
hybrid, support local business’, carpool,
and even planting more trees can help.
• None of these are overnight solutions but
if we all work to do some of these things
we can drastically help our planet.

10. Skeptic’s Views
• Unlike the alarmist’s view the skeptic’s
views vary but the two main ideas are that
either this warming is part of Earth’s
natural cycle (the Earth has been warming
and cooling ever since its beginning). Or
that this is all an effect from solar activity
and the temperature of the Earth.

11. Sun Theory
• As supplier of almost all the energy in
Earth's climate, the sun certainly has a
strong influence on climate change.
Consequently there have been many
studies examining the link between solar
variations and global temperatures.

12. Earth’s Natural Cycle Theory
• This theory is essentially saying that yes
there has been human interference but
nothing to the extent of what the alarmist
fear. This theory also states that the Earth
ahs warmed and cooled before as well as
had rises in the levels of CO2 and has
always gotten through it.

13. Facts to Back the Skeptic’s Sun
Theory
• Perhaps the best evidence of the sun
theory would be this graph showing the
temperature in comparison to solar activity

14. Fact’s to Back the Earth’s Natural
Cycle Theory.
• Some major evidence of the Earth’s
warming cycle would be the fact that
Greenland was originally in fact exactly
how it sounds… GREEN…
• Also the fact that the Earth witnessed a
medieval warming period that saw very
warm temperatures.
• As well as the little ice age that occurred in
the early 1800’s.

15. Skeptic’s Reasons to be Skeptic
• Skeptics say that global warming is just another
way for scientists to get significant funding for
their experiments.
• By making global warming out to be a
apocalyptic disaster of sorts the government has
been throwing money at scientists to find a
solution to this problem and learn more about it.
• So by saying your experiment has something to
do with global warming you are more likely to get
funds and more significant funds.

16. My View
• Too be honest I’m not really sure what to
believe about global warming right now.
Both sides have some very good points.
Now I would say naturally I would lean
towards the alarmist side just because I
always try and be as green as possible
whether it be through driving less or
recycling as much as possible.

17. My View Continued
• But too be honest right now I haven’t seen
enough evidence to make me believe that this
global warming is so significant we need to stop
the way we do everything and change right
away. Although I do strongly agree that with that
all the privileges we are given through
industrialization we need to use our intelligence
to make sure all the processes we use to make
our lives easier are efficient and have very little
harm on our environment.

18. My solution
• I think that we should slowly wean
ourselves off of all types of inefficient
energy sources and make an honest
attempt to preserves as much of our
planet’s rainforest’s and other natural
parts of the Earth. As well as taking little
steps to energy efficiency like hybrids,
energy efficient appliances, and using
solar and wind energy.
