hai guys... how are u. this my suggestion

As we know, global warming is one of the the natural disaster that we face in our life nowadays. These condition makes the earth feel more hot then the normal level. Global warming happen because the people burn the rubbish openly. The gases from there makes the level of temperature increase and it may bring a risk for our ozone layer. Indeed, the ozone layer being thinner and according to the reseordier there have a big hole in our ozone layer. Beside, these situation may increase the level of the water in the sea and may bring flood. So because of this dangerous situation, I want to suggest that we should create a video games software, which can gives an awareness to the public especially teenagers...hhuhuhuhuh....

Ways to prevent Global Warming...

hai guys..this four easy ways to help prevent Global Warming...

Step 1: Prevent global warming by minimizing drafts in your home.

One of the simplest and easiest ways to prevent global warming is to make sure all your windows and doors are draft free. Small gaps in your windows and doors can cause you to consume a lot more energy than you really need to in order to heat and cool your home. To make your home free from drafts wait until a cold day, then hold your hand along the edges of your doors and windows feeling for cold air. If you detect drafts, buy weather stripping from your local hardware store and install it wherever it is needed.

Step 2: Prevent global warming by reducing your waste electricity use.

Amazingly about 11% of residential electricity consumption is used by "phantom loads." A phantom load is caused when an electrical appliance draws electricity when it isn't in use. For example, a DVD player has an electrically lighted display that stays on even when you turn the power off. An easy way to eliminate these phantom loads is to plug your computers, printers, scanners, DVD players, televisions, etc. into multi-plug electrical surge protectors. Then, with one flick of the switch, you can make sure that the appliances plugged into your surge protectors are drawing no electricity at all.

Step 3: Prevent global warming with more efficient light bulbs.

One of the simplest ways to prevent global warming is by using more efficient light bulbs. The Union of Concerned Scientists tell us that if every American household replaced just one incandescent light bulb with a compact fluorescent one, then over the life of the bulbs 90 billion pounds of CO2 emission would be prevented from going into the atmosphere. This is like taking 6.3 million cars off the road!

Step 4: Prevent global warming by turning down your hot water heater.

Most of us have our hot water heaters turned up too high. If you turn down your hot water thermostat just 10 degrees Fahrenheit, you reduce 3% to 5% of your energy consumption. You'll have plenty of hot water if you set your water heater between 110-120°F.
These four simple ways to prevent global warming can be implemented quickly, easily, and with little to no expense.

Effects of global warming.....

The predicted effects of global warming not only impact the environment, but human life as well. Effects of global warming on the environment include glaciers, ecosystems and ocean currents, and sea level.

a) Impact On Glaciers

Global warming has so far and will continue to have negative effects on the glacier mass balance. From 1900-1980 there has been a recorded decline from 144 to 142 mountain glaciers. From 1980 to 2002 there has been a recorded net decline in all but a few mountain glacier masses. The biggest concern would be the failure of the glaciers in Hindu Kush and the Himalayas. These glaciers are the main water supply for China, India, and most of Asia. The complete melting of these glaciers would result in a major flow for several decades, however after that the most populated areas in the world could potentially run out of water.

b) Impacts On The Ecosystems And Ocean Currents

The continued increase in temperature will scientifically lessen the snow cap, create a rise in sea level, and produce weather changes. The combination of the effects of global warming will cause a change in the ecosystems. This change can potentially force animals out of their habitats endangering their existence and possibly even forcing them into extinction, while other animals may flourish. There is also the belief that global warming can affect ocean currents. An example of this would be the slowdown and likely shutdown of thermohaline circulation. This would lead to the localized cooling in the North Atlantic region such as Scandinavia and Britain who are warmed by the North Atlantic Drift.

c) Increase The Height Of Sea Level

A slight increase in sea level will make some densely populated coastal areas completely uninhabitable. For example, if the sea level raised a total of 4 meters practically every coastal city in the world would be drastically impacted creating major impacts on the world’s trade and economy. Within the next millennium a predicted 200 million people will be devastated with loss due to an irreversible glacier melt and rise in sea level. By 2100 the sea level is probably to rise 1 meter.

Causes of Global Warming....

There are many Causes of Global Warming such as Carbon Dioxide from Power Plants , Carbon Dioxide Emitted from Cars and Carbon Dioxide from Airplanes.

1) Carbon Dioxide from Power Plants

In 2002 about 40% of U.S. carbon dioxide emissions stem from the burning of fossil fuels for the purpose of electricity generation. Coal accounts for 93 percent of the emissions from the electric utility industry. US Emissions Inventory 2004 Executive Summary p. 10 Coal emits around 1.7 times as much carbon per unit of energy when burned as does natural gas and 1.25 times as much as oil. Natural gas gives off 50% of the carbon dioxide, the principal greenhouse gas, released by coal and 25% less carbon dioxide than oil, for the same amount of energy produced. Coal contains about 80 percent more carbon per unit of energy than gas does, and oil contains about 40 percent more. For the typical U.S. household, a metric ton of carbon equals about 10,000 miles of driving at 25 miles per gallon of gasoline or about one year of home heating using a natural gas-fired furnace or about four months of electricity from coal-fired generation.


2) Carbon Dioxide Emitted from Cars

About 33% of U.S carbon dioxide emissions comes from the burning of gasoline in internal-combustion engines of cars and light trucks (minivans, sport utility vehicles, pick-up trucks, and jeeps). Vehicles with poor gas mileage contribute the most to global warming. For example, according to the E.P.A's 2000 Fuel Economy Guide, a new Dodge Durango sports utility vehicle (with a 5.9 liter engine) that gets 12 miles per gallon in the city will emit an estimated 800 pounds of carbon dioxide over a distance of 500 city miles. In other words for each gallon of gas a vehicle consumes, 19.6 pounds of carbon dioxide are emitted into the air. A new Honda Insight that gets 61 miles to the gallon will only emit about 161 pounds of carbon dioxide over the same distance of 500 city miles. Sports utility vehicles were built for rough terrain, off road driving in mountains and deserts. When they are used for city driving, they are so much overkill to the environment. If one has to have a large vehicle for their family, station wagons are an intelligent choice for city driving, especially since their price is about half that of a sports utility. Inasmuch as SUV's have a narrow wheel base in respect to their higher silhouette, they are four times as likely as cars to rollover in an accident.

3) Carbon Dioxide from Airplanes

The UN's Intergovernmental Panel on Climate Change estimates that aviation causes 3.5 percent of global warming, and that the figure could rise to 15 percent by 2050.

(Ed Ayres, editor of Worldwatch magazine, Nov/Dec 2001)

“As human-caused biodiversity loss and climate disruption gain ground, we need to keep our sights clear and understand that the measure of a threat is not a matter of whether it is made on purpose, but of how much loss it may cause. It's an ancient habit to go after those we perceive to be evil because they intended to do harm. It's harder, but more effective, to "go after," meaning to more effectively educate and socialize, those vastly larger numbers of our fellow humans who are not evil, but whose behavior may in fact be far more destructive in the long run."
