Save energy to save money.

• The summer to save on heating and cooling costs.
• Install compact fluorescent light bulbs (CFLs) when your older incandescent bulbs burn out.
• Unplug appliances when you're not using them. Or, use a "smart" power strip that senses when appliances are off and cuts "phantom" or "vampire" energy use.
• Wash clothes in cold water whenever possible. As much as 85 percent of the energy used to machine-wash clothes goes to heating the water.
• Use a drying rack or clothesline to save the energy otherwise used during machine drying.Set your thermostat a few degrees lower in the winter and a few degrees higher in

Save water to save money.

• Take shorter showers to reduce water use. This will lower your water and heating bills too.
• Install a low-flow showerhead. They don't cost much, and the water and energy savings can quickly pay back your investment.
• Make sure you have a faucet aerator on each faucet. These inexpensive appliances conserve heat and water, while keeping water pressure high.
• Plant drought-tolerant native plants in your garden. Many plants need minimal watering. Find out which occur naturally in your area.

Less gas = more money (and better health!).

• Walk or bike to work. This saves on gas and parking costs while improving your cardiovascular health and reducing your risk of obesity.
• Consider telecommuting if you live far from your work. Or move closer. Even if this means paying more rent, it could save you money in the long term.
• Lobby your local government to increase spending on sidewalks and bike lanes. With little cost, these improvements can pay huge dividends in bettering your health and reducing traffic.

Eat smart.

• If you eat meat, add one meatless meal a week. Meat costs a lot at the store-and it's even more expensive when you consider the related environmental and health costs.
• Buy locally raised, humane, and organic meat, eggs, and dairy whenever you can. Purchasing from local farmers keeps money in the local economy.
• Watch videos about why local food and sustainable seafood are so great.
• Whatever your diet, eat low on the food chain [pdf]. This is especially true for seafood.

Skip the bottled water.

• Use a water filter to purify tap water instead of buying bottled water. Not only is bottled water expensive, but it generates large amounts of container waste.
• Bring a reusable water bottle, preferably aluminum rather than plastic, with you when traveling or at work.
• Check out this short article for the latest on bottled water trends.

Think before you buy.

• Go online to find new or gently used secondhand products. Whether you've just moved or are looking to redecorate, consider a service like craigslist or FreeSharing to track down furniture, appliances, and other items cheaply or for free.
• Check out garage sales, thrift stores, and consignment shops for clothing and other everyday items.
• When making purchases, make sure you know what's "Good Stuff" and what isn't.
• Watch a video about what happens when you buy things. Your purchases have a real impact, for better or worse.

Borrow instead of buying.

• Borrow from libraries instead of buying personal books and movies. This saves money, not to mention the ink and paper that goes into printing new books.
• Share power tools and other appliances. Get to know your neighbors while cutting down on the number of things cluttering your closet or garage.

Buy smart.

• Buy in bulk. Purchasing food from bulk bins can save money and packaging.
• Wear clothes that don't need to be dry-cleaned. This saves money and cuts down on toxic chemical use.
• Invest in high-quality, long-lasting products. You might pay more now, but you'll be happy when you don't have to replace items as frequently (and this means less waste!).

Keep electronics out of the trash.

• Keep your cell phones, computers, and other electronics as long as possible.
• Donate or recycle them responsibly when the time comes. E-waste contains mercury and other toxics and is a growing environmental problem.
• Recycle your cell phone.
• Ask your local government to set up an electronics recycling and hazardous waste collection event.

Make your own cleaning supplies.

• Join the Million Car Carbon Campaign by purchasing your Earth-Aid kit today.
• The big secret: you can make very effective, non-toxic cleaning products whenever you need them. All you need are a few simple ingredients like baking soda, vinegar, lemon, and soap.
• Making your own cleaning products saves money, time, and packaging-not to mention your indoor air quality.

Global Worming Causes

World View of Global Warming is an independent documentary project by photojournalist Gary Braasch, now in its 11th year, presenting a comprehensive look at global warming science, the world wide effects of climate change, its implications, and what action is being taken about it. Braasch documents this change through science reporting and photography from the Arctic to Antarctica, from glaciers to the oceans. Rapid climate change is occurring now and its effects are fast becoming one of the prime events of the 21st century.

What Causes Global Warming?

Scientists have spent decades figuring out what is causing global warming. They've looked at the natural cycles and events that are known to influence climate. But the amount and pattern of warming that's been measured can't be explained by these factors alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans.To bring all this information together, the United Nations formed a group of scientists called the International Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming. Each report represents a consensus, or agreement, among hundreds of leading scientists.

One of the first things scientists learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture (especially from the digestive systems of grazing animals), nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2.

Different greenhouse gases have very different heat-trapping abilities. Some of them can even trap more heat than CO2. A molecule of methane produces more than 20 times the warming of a molecule of CO2. Nitrous oxide is 300 times more powerful than CO2. Other gases, such as chlorofluorocarbons (which have been banned in much of the world because they also degrade the ozone layer), have heat-trapping potential thousands of times greater than CO2. But because their concentrations are much lower than CO2, none of these gases adds as much warmth to the atmosphere as CO2 does.

Most Causes of Global Warming

1. Carbon dioxide emissions from fossil fuel burning power plants
2. Carbon dioxide emissions from burning gasoline for transportation
3. Methane emissions from animals, agriculture such as rice paddies, and from Arctic seabeds
4. Deforestation, especially tropical forests for wood, pulp, and farmland
5. Increase in usage of chemical fertilizers on croplands
6. Rise in sea levels worldwide
7. More killer storms
8. Massive crop failures
9. Widespread extinction of species
10. Disappearance of coral reefs

Causes of Global Warming

Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.

Greenhouse Gases and Global Warming

While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.

The Consequences of Global Warming

As the concentration of greenhouse gases grows, more heat is trapped in the atmosphere and less escapes back into space. This increase in trapped heat changes the climate and alters weather patterns, which may hasten species extinction, influence the length of seasons, cause coastal flooding, and lead to more frequent and severe storms.

How Do You Contribute?

If you want to help stop global warming, you have to understand how your actions are causing it. The main causes of global warming, in order of the magnitude of their impact, are:

Carbon Dioxide from:

• Fossil Fuel
• Deforestation
• Failing Sinks

Methane from:

• Cattle and Rice Paddies
• the Artic Tundra
• Clathrates

Nitrogen Oxides from Farming
Other Gases
