Introduction

• Global warming is when the earth heats up and the temperature increases

• More recently, the temperatures have been rising, causing more dangers for people, animals, plants and our environment.

The U.S. emits about 6.4 billion metric tons of greenhouse gases annually, 25% of the world’s total.

Carbon dioxide stays in the atmosphere for approximately 100 years, methane lasts about 12 years. Other greenhouse gases last even longer.

As these gases continue to raise surface temperatures, they trigger the release of even greater quantities of carbon dioxide and methane that are currently trapped in frozen Arctic permafrost and tundra soils, further increasing temperatures.

…potentially causing “runaway global warming”.

These greenhouse gases last a long time…

Warming begets more warming…

A feedback mechanism ensues…

Causes of Global Warming•Electrical pollution is a main cause for Global Warming. Mostly, fossil fuels are burned to create electricity and are made of dead plants and animals. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.

•When we throw our garbage away, the garbage goes to landfills which are sometimes burned. This sends an enormous amount of greenhouse gasses into the air and makes global warming even worse.

•Another factor that makes global warming worse is when trees are cut down. Trees and other plants collect and absorb carbon dioxide (CO2), which is a greenhouse gas.

The Greenhouse Effect

Remedies

Because greenhouse gas emissions are tied very closely to our energy consumption, using less fossil fuel based energy puts fewer greenhouse gases into the atmosphere.

This will help slow global warming.

1.Reduce our consumption of fossil fuels

50% of electricity in the United States is produced from coal.

2.Small changes really add up

Replace your old refrigerator with a new Energy Star: Annual savings: $90; 700 pounds CO2

Set your thermostat down a few degrees in the winterAnnual savings: $135; 1400 pounds CO2

Wash clothes in cold water onlyAnnual savings: $70; 500 pounds CO2

Drive JUST 10 fewer miles per weekAnnual savings: $80; 520 pounds CO2

Reduce your garbage by 10% through greater recycling or reduced packagingAnnual savings: 1200 pounds CO2

Caulk and weather-strip around doors and windowsAnnual savings: $80; 650 pounds CO2

* These are mid-range estimates from published sources; your savings may vary.

3.Save Energy.• Turning off lights saves energy and money. The more energy used, the more rivers are dammed or more fossil fuel is burned, causing air pollution

and increased levels of carbon dioxide in the atmosphere

4. Save Resources.• Throwing away containers of any kind wastes energy and resources and adds to our waste problem. Many towns are running out of landfill space.

5.Promote Car pooling.• Our reliance on cars that burn fossil fuels is one of the major causes of increased levels of carbon dioxide in the atmosphere and it is the primary

cause of urban smog.
