Steps taken by all the countries to reduce global warming?

Yes, the steps are :

1. Reduce, Reuse, Recycle

Do your part to reduce waste by choosing reusable products instead of disposables. Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste. And whenever you can, recycle paper, plastic, newspaper, glass and aluminum cans. If there isn't a recycling program at your workplace, school, or in your community, ask about starting one. By recycling half of your househ

2. Use Less Heat and Air Conditioning

Adding insulation to your walls and attic, and installing weather stripping or caulking around doors and windows can lower your heating costs more than 25 percent, by reducing the amount of energy you need to heat and cool your home.

Turn down the heat while you're sleeping at night or away during the day, and keep temperatures moderate at all times. Setting your thermostat just 2 degrees lower in winter and higher in summer could save about 2,000 pounds of carbon dioxide each year.

3. Drive Less and Drive Smart

Less driving means fewer emissions. Besides saving gasoline, walking and biking are great forms of exercise. Explore your community mass transit system, and check out options for carpooling to work or school.

When you do drive, make sure your car is running efficiently. For example, keeping your tires properly inflated can improve your gas mileage by more than 3 percent. Every gallon of gas you save not only helps your budget, it also keeps 20 pounds of carbon dioxide out of the atmosphere.

5. Buy Energy-Efficient Products

When it's time to buy a new car, choose one that offers good gas mileage. Home appliances now come in a range of energy-efficient models, and compact florescent bulbs are designed to provide more natural-looking light while using far less energy than standard light bulbs.

Avoid products that come with excess packaging, especially molded plastic and other packaging that can't be recycled. If you reduce your household garbage by 10 percent, you can save 1,200 pounds of carbon dioxide annually.

6. Use Less Hot Water

Set your water heater at 120 degrees to save energy, and wrap it in an insulating blanket if it is more than 5 years old. Buy low-flow showerheads to save hot water and about 350 pounds of carbon dioxide yearly. Wash your clothes in warm or cold water to reduce your use of hot water and the energy required to produce it. That change alone can save at least 500 pounds of carbon dioxide annually in most households. Use the energy-saving settings on your dishwasher and let the dishes air-dry.

Fluorescent Light Bulbs

Compact Fluorescent Light Bulbs: Change a Light Bulb and Change the World

If you want to change the world, start by changing a few light bulbs. It is one of the best things you can do for the environment—and your budget. According to the Union of Concerned Scientists, if every U.S. household replaced just one regular incandescent light bulb with a compact fluorescent light bulb, it would prevent 90 billion pounds of greenhouse gas emissions from power plants, the equivalent of taking 7.5 million cars off the road. And the U.S. Environmental Protection Agency says that by replacing regular light bulbs with compact fluorescent light bulbs at the same minimal rate, Americans would save enough energy to light more than 2.5 million homes for a year.

Reasons to Switch to Compact Fluorescent Light Bulbs

On top of that, replacing one regular light bulb with an approved compact fluorescent light bulb would save consumers $30 in energy costs over the life of the bulb. Compact fluorescent light bulbs use at least two-thirds less energy than standard incandescent bulbs to provide the same amount of light, and they last up to 10 times longer. Compact fluorescent light bulbs also generate 70 percent less heat, so they are safer to operate and can also reduce energy costs associated with cooling homes and offices. The only real drawback to using compact fluorescent bulbs is that each one contains about 5 mg of mercury, a toxic heavy metal that can cause serious health problems if inhaled or ingested over a period of time or in large enough doses. As a result, many environmentalists and other experts recommend recycling compact fluorescent bulbs to make sure they don't end up in landfills.

How Much Can You Save by Using Compact Fluorescent Light Bulbs?

For most people, switching from incandescent to compact fluorescent bulbs offers a lot of opportunity for energy and cost savings. Lighting accounts for 20 percent of the electric bill in the average U.S. home, and the average home has approximately 30 light fixtures. (Calculate your personal energy and cost savings with this handy online calculator, and find out how much you will be helping the environment.)

To save the most energy and money by using compact fluorescent light bulbs, the U.S. Environmental Protection Agency recommends replacing standard bulbs in areas where lights are used frequently and left on for a long time, such as family rooms, living rooms, kitchens, dining rooms, and porches.

Choosing the Right Compact Fluorescent Light Bulbs

To make sure you get the same amount of light when replacing standard bulbs with compact fluorescent light bulbs, check the lumen rating on the light you are replacing and purchase a compact fluorescent light bulb with the same lumen rating. (A lumen rating is the measure of light the bulb puts out.) Wattage varies greatly between standard light bulbs and compact fluorescent light bulbs. Compact fluorescent light bulbs typically use about one-quarter of the wattage used by standard bulbs to produce the same amount of light. So to replace a traditional 60-watt bulb, look for a compact fluorescent light bulb that is about 15 watts. Compact fluorescent light bulbs are available in many different sizes and shapes to fit in almost any fixture—from three-way lamps to dimmer switches—for both indoor and outdoor use. Compact fluorescent light bulbs also come in a variety of color temperatures, which helps determine the color and brightness of the light each bulb provides. (Learn more about the brightness,color and light quality of compact fluorescent light bulbs.)

Keeping It Simple

None of this is as daunting as it may seem. But to make it really simple, the environmental group Environmental Defense has put together an easy-to-use web site that lets you search for the compact fluorescent light bulbs according to where you want to use them or by shape, brightness, color of light or other features. The site also features user reviews of specific bulbs, and side-by-side photos of energy-saving compact fluorescent light bulbs with incandescent bulbs to help you determine whether the fluorescent bulbs will fit your light fixture. With all of the choices now offered by compact fluorescent technology, saving energy, saving money, and protecting the environment is as easy as changing a light bulb.

Implement steps against global warming

1. Change standard incandescent light bulbs in your home and place of work. Use compact fluorescent bulbs instead of incandescent bulbs. Compact fluorescent bulbs use less electricity, give off the same amount of light and are less expensive to use. This will help the environment and save you on your electric bill.

2. Replace old electronics and other appliances with energy efficient ones. Many stores carry energy efficient model appliances such as stoves, refrigerators, washer and dryers and air conditioners. You will be able to easily identify these appliances with the energy

3. Lessen your electrical usage. This can easily be accomplished by making sure lights are turned off in rooms where no one is present. Also, unplug all non-essential appliances (DVD players, stereos, televisions and more) when they are not being used and this will cut down on what is known as phantom load that occurs with appliance that still draw energy even when not being used.

4. Install water saving shower heads and faucets. These utilize a low-flow system that will allow the homeowner to use half the amount of water, while not hindering performance and function. Keeping with water conservation, it can benefit the environment and the consumer greatly to turn down the hot water heater temperature to 120 degrees F. This is a simple way to do your part in the fight against global warming, while seeing hot water costs going down.

5. Switch to environmentally and globally safe cleaning products. These products are commonly known as "green" products because they are safe for the environment. So, look for products that are "eco-friendly."

6. Learn to recycle. In most every community in the United States, there is a recycling program initiative. Recycling paper, plastics, glass products and metals can dramatically cut down on the pollutant gases that are emitted at landfills. Also, learn to buy products that are made from recycled material.

7. Plant some trees. One of the biggest problems about global warming stems from foresting practices like logging and slash and burn farming. Combine this with intensive livestock practices that are incorporated by big farm corporations and you have the main reason for 90 percent of forests in the United States being destroyed. Destroying forests only adds more carbon dioxide into the atmosphere since trees absorb carbon dioxide. So, plant a tree and shade your neighborhood naturally.

8. Tune up your car periodically. Make sure your tires are inflated properly because this can lessen the amount of gas your car has to burn. For two car families, try to drive the car that gets better gas mileage more often.

9. Leave the car at home. Whenever possible, walk, bicycle or use public transportation. This will cut down on harmful car emissions released into the environment.

10. Switch to organic food products. These products are produced through environmentally sound means and are healthier for human consumption. Many of these organic food products are commonly found in today's grocery store, making it easier to switch to these more nutritious and environmentally safe products. There are organic eggs, cheeses, milk, meats, fruits and vegetables and breads. The selection is in abundance; but it is up to you to make this simple switch which can send a strong message to corporate farms that utilize non-environmentally safe practices to produce food.
