Transcript of Global Warming

Global warming =
increase of average temperature on earth
It is a
natural
process
started
18,000
years ago
Ice Age
Ice Age
100,000 years
global warming
warm climate
15,000 - 20,000 years
global cooling
humans
didn't cause
global warming
The End..
Thanks for watching
Global Warming
Global Warming:
Affects -
- our Weather
- Rising Sea Levels
-Wild life

Green House Gases Warming Our Atmosphere:
Water Vapor
Methane

You release Methane when you do things like..
Decomposition of Waste in Landfills
Agriculture and Rice Cultivation
Nitrous Oxide

Commercial and Organic Fertilizers
You Release Nitrous Oxide when you do things like:
Fossil Fuel Combustion
Nitric acid production
Biomass Burning
Chlorofluorocarbons
Carbon Dioxide

Destroys Ozone Layer

Humans Cause Global Warming..
Extreme Weather
Floods
Droughts
Heat Waves
Hurricanes
Wild Fires
Rainfall rates have indeed increased 10-31%
Floods happen more frequently and to be more severe
1.3 billion dollars in crop loss
Drought have also been become very severe especially in vulnerable places like the the South East.
Longer fire seasons, fires occur more frequently and they spread through a bigger surface area
In just Georgia and Florida alone wildfires have destroyed 600,000 acres of land.
Unprecedented heat in the summer of 2003 caused an estimated 70,000 premature deaths in Europe. As shown on the map, temperatures that summer in parts of Europe were 5-10°C (9-18°F) higher than in 2001. Such blistering summers could become the norm by late this century if greenhouse gas emissions aren’t reduced.
Wind speeds of hurricanes have increased 10-13% and 12 hurricanes have made damages over a billion dollars. Hurricane Katrina was one of them, she made damages over 125 billion
Rising Sea Levels
Sea Levels are rising at a rate off 3.1 millimeters a year
Higher sea levels will occur because the arctic ice melts every year. Once the ice melts all that water is pumped into the ocean where it floods many cities on Earth.
Miami in 20 years:
Miami is already have huge trouble with rising sea level. They’re worried that the ocean will flood the runway near the beach and they are already experiencing traumatic contamination of fresh water.
All Wildlife need..
- the right temperatures
-fresh water
-food sources
- a place to raise their young
Rising temperatures has already been melting arctic ice, which removes hunting ground for Polar Bears.
Warmer water causes population declines for fish such as trout and salmon for they need cold water to survive.
Severe droughts stress and can kill plants on which wildlife depend for food and shelter, and deprives wildlife of water sources.
Climate change had also altered food availability for migratory species; birds for instance arrive on schedule to find their food sources such as insects, seeds and flowering plants but because of global warming they have either hatched or bloomed too early or not at all.
The polar Bear

Scientists predict that by 2050, 67% of our polar bears will disappear.
The Pika
These furry creatures need the cold air, for if they are exposed to the heat they can die in a matter of hours.
Waterfowl
Global warming is impacting waterfowl around the world, changing their habitats, food sources and migration cycles.
significant declines in Prairie Pothole wetlands could lead to a 9-69 percent reduction in the abundance of ducks
Our Climate is changing so fast that species are not able to adapt to this rapid climate change. Help stop Global Warming NOW!!
How we can help:
save energy by-
-Pick a Green-e-certified energy supplier
-Purchase Carbon Offsets
- Drive smarter cars

(ones that don't release much greenhouse emissions)
-Drive less
-Replace your light bulbs with compact fluorescent bulbs
-Heat/cool your home as little as possible
It's your time to take action
