Global Warming IS a Fact

This NASA Image shows the Polar Cap in 004

This NASA image shows the Arctic Polar ice cap in 2004. The 1979 ice boundary superimposed. Compared to 1979, the north polar ice cap is now 20% smaller during the summer. Arctic temperatures are rising twice as fast as they are in the rest of the world.
The planet IS warming.
Over the last century, the world's average temperature has increased about 1 Fahrenheit
In the Northern Hemisphere, spring thaw begins 9 days earlier than it did 150 years ago, and the fall freeze starts 10 days later.
The hottest years on record are 1998, 2002, 2003, 2001, and 1997.
There is more warming at higher latitudes.
In the past 50 years, average temperatures have increased 4 -7 Fahrenheit in Alaska, western Canada, and eastern Russia.
In Barrow, Alaska, average temperatures have risen
4 Fahrenheit in 30 years -- almost twice the global average.
The United Nations' Intergovernmental Panel on Climate Change says global temperatures will rise up to
10 Fahrenheit by century's end.
Arctic ice is at risk.
Rising temperatures have a dramatic impact on Arctic ice, which serves as an "air conditioner" at the top of the world. Since 1978 Arctic sea ice area has not only thinned, but it's shrunk 9% per decade.
ACIA projects that at least half of the Arctic's summer sea ice will melt by century's end, and that the Arctic region is likely to warm
7-13s Fahrenheit during the same time.
The Arctic impacts affect people and animals.
Coastal Indigenous communities report shorter periods of sea ice, causing more ocean storms and coastal erosion.
Increased snow and ice melt causes rivers to rise.
Thawing permafrost ruins roads and other infrastructure. Some communities have been forced to move from historic coastline locations.
Sea ice loss is devastating for animals like polar bears and ringed seals in the Arctic and Antarctic penguins. They depend upon that environment to live.
Greenland's ice sheet could melt. Over the very long term, Greenland's massive ice sheet holds enough melt water to raise sea level by about
23 feet. The ACIA predicts this ice sheet will melt throughout the 21st century.

Glaciers are shrinking
In 1910, Montana's Glacier National Park held some 150 glaciers. Now fewer than 30, greatly shrunken glaciers, remain.
Tropical glaciers are in even more trouble. The snow on Tanzania's Mount Kilimanjaro
19,340-foot peak have melted by 80% since 1912 and could be gone by 2020.

Sea levels have risen
Average global sea level rose 4 - 8 inches in the 20th century
Sea levels could rise between
4 - 35 inches by 2100. A 1.5-foot sea level rise in flat coastal areas would cause the coastline to retreat by 150 feet. 100,000,000 people worldwide people live within 3 feet sea level.
Rising seas would promote flooding in many areas, including Florida, Louisiana and many South Sea Islands. The Indian Ocean nation of Maldives, whose maximum elevation is
8 feet, has built a sea wall around the capital, Male, to protect it.

Warming could alter the ocean conveyor belt
The ocean's circulation system is known as the ocean conveyor belt. It moves tropical heat around the planet to help balance global temperatures. With freshwater input from melting ice caps, for instance, this system would lose it's balance, creating unforeseen and fast-paced change.

Extreme weather could become common 
Global warming could cause more frequent and extreme weather conditions such as storms, hurricanes, heat waves, fires, and droughts.

Human activities have contributed to global warming
Since the 1860s, industries and shrinking forests have helped raise the atmosphere's CO2 level by almost 100 parts per million. In the Northern Hemisphere, temperatures and greenhouse gasses have forced even larger increases since the 1950s.
Water vapor is the most important greenhouse gas. Carbon dioxide, methane and nitrous oxide also contain heat and help keep Earth's temperate climate balanced. Human activities, burning fossil fuels and clearing forests produced these gases faster than plants and oceans can soak them up. The gases remain in the atmosphere for
100 years. Even an complete halt in emissions would not stop the warming for many years.

Global warming affects plants, birds and amphibians also.
Since the 1950s, many European plants flower a week earlier and lose their leaves 5 days later.
Birds and frogs are breeding earlier
in the season.
Some butterflies now range
2 - 150 miles farther north than they did a few decades ago.

Warming could cause plant and animal extinction.
By 2050, carbon dioxide and other greenhouse gases could force the extinction of more than 1,000,000 of Earth's land-dwelling plants and animals.
Coral reefs are also affected.
Coral reefs worldwide are "bleaching," losing key algae and resident organisms, As water temperatures rise above 85 in warm, sunny weather, coral reefs are losing key algae and organisms. Many species cannot adapt to this change within interdependent ecosystems.
What You Can Do To Help!
1. Reduce Carbon Dioxide Emissions by about 500 pounds per year:  Replace your current washing machine with a low-energy, low-water-use machine. (440 pounds).  Wash your laundry in warm or cold water, instead of hot. (60 pounds).
2. Reduce Carbon Dioxide Emissions by about 1,000 pounds per year:  Wrap water heaters older than 5 years in an insulating jacket.
3. Reduce Carbon Dioxide Emissions by about 550 pounds per year:  Keep your water-heater thermostat no higher than 120 F.
4. Reduce Carbon Dioxide Emissions by about 450 pounds per year:  Replace old, energy inefficient appliances with newer efficient models. For list of energy-efficient appliances, visit: (www.energystar.gov).
5. Reduce Carbon Dioxide Emissions by about
1,000 pounds per year:  Reduce your garbage by 25% and reduce carbon dioxide emissions.
6. Reduce Carbon Dioxide Emissions by about 850 pounds per year: Recycle aluminum cans, glass bottles, plastic, cardboard, and newspapers.
7. Reduce Carbon Dioxide Emissions by about 1,000 pounds per year:  Caulk and weather strip around doors and windows to plug up leaks.
8. Reduce Carbon Dioxide Emissions by 1,590 pounds per year:  Leave your car at home two days a week and walk, bike, or take public transit.
9. Reduce Carbon Dioxide Emissions With your Car:  Find a car that gets more miles to the gallon. The potential carbon dioxide reduction for a car that gets 32 miles per gallon is 5,600 pounds per year.
10. Make the Right Mov:  Move closer to work and reducing your commute.
11. Turn Off:
  Turn off your TV, video player, stereo, computer, and lights when you aren't using them, and you start saving within a minute or two.
12. Baby your Car:  Tune-up your car and could boost your miles per gallon from 4- 40%.
A new air filter could increase mpg by
10%.
Take your roof rack off your car when you aren't using it.
