Title: Global Warming can destroy our planet
1Global Warmingcan destroy our planet!
- If we just sit and do nothing about it.

2Changes
- Scientific consensus is that human activity,
mainly carbon dioxide emissions, is causing
global warming. - Every time we use electricity or gasoline, we are
sending CO2 emissions to the atmosphere.
3Global Warming
- World before Industrial revolution, 1800
- CO2 level low
- No fossil fuel emissions (oil, coal, gas).
- Weve had a global climate equilibrium for the
last 100,000 years its like we had a very
comfortable blanket developed specially for us. - Now we have a huge blanket (caused by the extra
human-made emissions in the atmosphere) - made of heat-trapping, heat-emitting IR
greenhouse gases.

5- How hot will the Earth be in a few years?
- Depends on us.

6CO2 in the atmosphereYears 1960-2000
7CO2 in Atmosphere Years 1000 -2100
8Earths Surface Temperature Years 1000 -2100
How hot it ultimately gets depends on us.
9Global average temperatureYears 1860-2000
10Consequences
- Polar caps melt
- Sea level rise
- Extreme temperatures
- Cyclones/tornadoes
- Drought / floods
- Disease
- Agriculture losses
- Extinction of animal species, corals, vegetation
- Worst case scenario stop ocean conveyor belt
11Kilimanjaro (Tanzania, Africa)
30 years later
12Lake Chad
- Was the 6th largest lake in the World!
- A study by U. Wisconsin-Madison and NASA's EOS,
the lake is now 1/20th of the size it was 35
years ago. - W. Africa (Chad, Niger, Nigeria, Cameroon), the
region has suffered from an increasingly dry
climate, experiencing decline in rain since early
1960s.
We are causing Extreme poverty in Africa due to
our emissions which accounts for 25 of all world
emissions compared to Africas 3.
13Patagonia (Argentina)Longest Glacier in S.A.
1928 2004
14Costa Rica
- First official lost species due to Global
warming - the golden toad
- Female Male
15Hurricanes
- 10 hottest years ever, occurred in the last 14
yrs. - 2003 1st hurricane ever in the S. Altantic Ocean
- 2005 highest of hurricanes,
- most intense, 6 Greek letters
- 2005 Wilma strongest hurricane ever recorded AO
- Then
- 2006 Monica strongest hurricane ever recorded
- Luckily, this year (2006), El Niño decreases
hurricanes
16Icebergs with caves broken food chain
60 of krill population killed because of this.
Krill are small shrimp-like crustaceans
zooplankton, food for baleen whales, mantas,
whale sharks, seals, and a few seabird species
17Worst case scenario abrupt changeIPCC
(Intergovernmental Panel on Climate Change)
Due to change in salinity, if Artic keeps
melting, this current could stop, creating a
small ice age in Europe and North America.
18On top of this
- New blooming economies want to live their own
version of the American Dream.
Example in China, the traditional bicycle lane
was closed to lay way to an extra automobile
lane. India is now also flourishing economically
and greatly increasing their CO2 emissions.
19Potential Solutions
- Reduce CO2 emissions
- Reduce energy consumption
- Alternative green power solar, wind
- Reforestation
- Increase fuel efficiency e.g. fuel cell, hybrid
cars - Emission trading- Kyoto Protocol signed by 135
nations in Kyoto, Japan to reduce emissions. - Not signed by U.S. or Australia!, the 2 nations
with the highest emissions.
20The Good News is
21Weve done it before! Ozone Layer Montreal
Protocol's ban on CFCs
- For years, chlorofluorocarbons (CFCs) were the
agents--contributing to the destruction of the
Earth's ozone layer. - After the Montreal Protocol's ban on CFCs,
slightly-more benign HCFCs replaced them..
The ozone layer is healing, but there is still a
higher incidence of skin cancer and other
diseases in the World due in part by this hole.
22More Good News
- You can save over 2,000 every year while helping
the planet!
23Top 16 Things Save with NO initial cost
- Turn off (or even better, unplug) appliances
- (consider a power strip), cord instead of
cordless phones - Turn off water faucet,
- shower not baths, flow
- change shower head
- Clean air-conditioning filters
- Tune-up car, keep balanced,
Accelerate minimum only - MPG
24- Turn down Water heater, and air
conditioner - Use sheets instead of blankets
- Turn off PC, printers, when not using
- Use Laptop instead of PC
- Use cold water for washing cloths!
- Hang clothes if possible
- Use dishwasher only when full
- Wash by hand if possible
25- Eating habits
- Eat less meat (less methane)
- Eat local products
- Plant trees
- They also lower house T in summer,
- They reduce CO2
- Car pooling, walking or biking
- Avoid sanitary dishes/napkins
- Both styrofoam or paper
26- Buy products with least packaging
- Large family packs
- Gift bags instead of wrapping
- Water bottles! ? - use refillable bottle.
Packaging and clean water production needs a lot
of energy and releases tons of CO2 in the
atmosphere annually.
27- Be a wise consumer
- Buy less
- Give away things you not longer use.
28- Recycle!
- (plastic, paper, cardboard, cans, glass)
- Email your senators, government officials
- Sign petition at www.undoit.org
- Sign petition at climatecrisis.org
29Top 11 Things Save with some initial cost
- You will recover the initial costs quickly and at
the same time, reduce emissions greatly. - Consider solar water heater
- Replace light bulbs with coiled fluorescent
30Top 11 (cont)
- Consider new appliances with Energy Star
- MYTH Not all new appliances are energy
efficient!! Check the labels carefully.
31Top 11 (cont)
Transportation accounts for 67 of oil used!
- Consider buying a small car or a Hybrid,
- Use public transportation
- Eat organic products (better health, less Br)
- Consider wind or solar power
- Use silicone or dark baking pans
- Use reusable plastic or cloth coffee filter
- Use rechargeable batteries
Green means its also good for your HEALTH.
32Small changes, make a big difference
33In summary
- ave Money, improve your Health, Save the Planet!
In doing so, we are indirectly helping the
extreme poor is our moral responsibility.
34Political Issues
- Oil industry interests,
- Lobbyists
- Governments covering up scientific evidence
- (e.g. NASA climatologist, Jim Hansen)
- Real cost of nuclear energy
- Should include the cost of waste disposal and the
cost of medical treatment of potential health
diseases due to radioactive materials. - versus cost of clean energy like solar or wind.
35Take action!
Stop Global Warming
36With your helpwe can save the World!
We are ONE human race we only have
ONE planet. Lets use its resources
efficiently so that we can all benefit from it.
