2. Global warming + The Greenhouse Effect
Global warming is defined as an increase in the average
temperature of earth’s atmosphere, either by human
industry and agriculture or by natural causes like the
earth has experienced numerous times through its
history.
The Greenhouse effect is a warming effect caused by
certain gases that retain heat from sunlight. Without
such gases the earth would be below freezing. The
global warming debate is centered on whether added
greenhouse gases released by human activity will
overheat the earth and cause harmful effects.
5. Carbon Dioxide CO2
Generally a colorless,
odorless, non-toxic gas.
The most important
greenhouse gas
Contributes more to the
greenhouse effect than any
other gas released by
human activity
Humans release about 37
billion tons of CO2 per year
6. Facts About Global warming
90% of the global warming
has been caused by human
factors since 1950.
The hottest decade
spanned from 2000-2009.
The sea level has risen
approx. 1 inch. At this rate,
it will become a serious
problem by 2100
There has been an 11%
increase in CO2 levels since
1950
When the earth was 9
degrees cooler, the ice over
NYC was over 2000 feet
thick. There is a chance
that the earth will be 9
degrees hotter by 2100
The Year 2011 saw the most
Co2 dumping at about a
rate of 1000 tons/second
into the air.
China emits 40% more CO2
than the U.S.
7. More Facts…
Since the industrial
revolution in the late
1700’s the CO2
concentration in Earth’s
atmosphere has increased
by about 34%, most rapidly
from 1960 onward.
8. Major Contributors to Global Warming.
The use of Fossil Fuels
The livestock industry
A reduction in the sun’s
output of cosmic rays which
lessens the amount of
clouds that exert a cooling
effect on the earth
Sulfur pollution from coal
use in Asia
Ocean circulation that
affects how much cold
water rises to the surface,
which affects how warm or
cold the atmosphere is
9. Evidence of
Climate Change
Glacier shrinking is an evidence
of climate change. Between
2002-2005 greenland lost 150-250
cubic Km of ice every year, and
Antarctica lost 152 cubic Km.
The Arctic sea is losing its ice at
a rate of 11.5% per decade.
10. The Cost of Global Warming
Massive ice glacier melts. A continued trend in this
direction will lead to a rise in the sea level, with
projections indicating a 7-23 inch rise by the end of the
century.
This will affect millions of people living by the
coastlines, as well as wildlife too.
The Polar bear is an endangered species due to the
effects of global warming.
In 2007 residents of Tegua islands had to be evacuated
due to rising sea levels.
11. The Cost of Global Warming
As of the 1950’s the Arctic sea has diminished approx. 15%
Montana’s glacier national park had 150 glaciers in 1910. It
now only has 27
25% of Australia’s crop production in 2007 was lost to
desertification.
Developing countries have to rely on food aid due to failed
rains in their countries.
Extreme weather: Frequent wildfires, floods in Haiti,
earthquakes in Japan, Hurricanes in the U.S. droughts in
Africa.
14. But How Can I Help?
Recycle: paper, plastic,
newspaper, glass, aluminum
cans. By recycling half of
your household waste, you
can save 2400 lbs of carbon
dioxide annually.
Use less heat and Air
conditioning: adding
insulation to your walls and
attic can lower heating
costs by more than 25% and
can save about 2000 lbs of
carbon dioxide a year.
Change lightbulbs: use CFL
bulbs. They last 10x longer
than incandescent bulbs
and use 2/3 less energy.
Drive less: it saves
gasoline. Every gallon of
gas you save keeps 20lbs of
CO2 out of the atmosphere
Buy energy efficient
products: buy cars with
good gas mileage, CFL
lights, avoid products with
excess packaging.
15. But How Can I Help?
Use Less hot water: buy low
flow showerheads, use
energy saving settings on
your dishwasher and let
dishes air dry. This can save
500 Lbs of CO2 annually
Use the off switch: turn off
lights and electronics when
you leave a room, don’t
leave water running while
not using it
Plant a Tree: They absorb
CO2 and give off oxygen.
One tree absorbs one ton of
CO2 during its lifetime.
Get a report card from your
utility company: they can
provide free home energy
audits to help identify areas
in your home that may not
be energy efficient
Encourage others to
conserve: share this info
with others. It will go a long
way towards reducing energy
and your monthly budget.
