this is my contribution on global warming
and check out a documentary called --is tsunami man made-on discovery channel,about a super tranmittor called HAAARP
in North Africa,India,Mexico ,millions of people are effected by land loss and desertification
in recent times thousands of people have died because of exessive heat,usually old people.in India ,Mexico and France,
deforestation causing desertification,the desert conditions causing very cold nights and scorching hot days
in china, thousands of what used to be farmers are running for their lives from the dust storms that have burried their towns and turned their lands into dessert,the globe where they were got to hot for them .
and instead of producing food they are now needing it from some where else,and they will drastically effect the world food prices when they start buying water in the form of grains ,at any cost destabalising governments, in some countries ,could be the result
(are you seeing more Chinese around interested in agricultural lands ,we do here in Mexico)
,the Sahara is growing by 7 kilometers a year
and all of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were no desserts.
collectively this planet is drying up because of bad farming practices like,over grazing and fertilizers,
as far as the food production is concerned, Global warming or some of its effects are serious,rising seas result in landloss
each degree rise in temperature means 10%crop loss
more landloss because of desertification every year,we have less areble land to produce food ,for an extra 70 million people ,
and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
who are overpumping deep carbon aquifiers
who are plowing more and more unstable lands because they have lost so many million hectares to desertification ,
because of bad farming practises ,such as using fertilizers and heavy machinary or over grazing
RISING SEAS
The northpole is melting ,and we will know it without ice in our life times.
this does not affect the sea level because it is ice that is already in the water.but the melting ice from Green land and the south pole ,are another matter.
Global warming is in theory reversable,but it will mean global co operation between all countries ,and taking into account human nature and the world politics ,it is unlikely that this will happen,
At least not untill we are all in the middle of planetary disastres and it becomes a battle for the survival of humanity every where.
SOLUTIONS
if you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to reverse the destructive processes
reduce carbon emisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,powerplants etc.
the capture of carbon and the production of water and assist the aquiferous manta.
the world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia
Waterharvesting projects ,such as millions of small dams.to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.
the protection of existing forrests.
stop building more highways,urban planning to include vegetation stop building cities encourage people to return to the land to conduct their business from there which now has become possible thanks to the internet.
education to motivate people to auto sufficiency by building more home food gardens.
education on environmental awareness
education on family planning to curb over´populaion
Agricultural education and improvements to follow the principals or sustainability and soil management.
more environmental or land ,design to prevent bush fires,such as--fire breaks
,more dams.regulations and control for public behaviour
alternative effeciant public transport to discourage the use of the internal conbustion engine
recicling wastes,limit water use

Start a teen council and get others to join your group. There is more power in high numbers of people.... I'm in America.....Arizona.... And I am a believer that something is going wrong with the global warming and other things happening. Some things need to be done and right away. But most people are lost as to what to do and how to go about it. I personally think that our world's population has a lot to do with it too. There are just too many people and everyone wants to live by their own rules. I think we need to start reducing the amount of people being born... That's just another way of helping.....

Well at least you are thinking. This is a hoax, why am I so sure. I look at the scientists that are saying that it is and that they have nothing to gain for saying the truth. THese "scientists" that say mankind are the cause for this are getting grant money and have an agenda. There is a climatologist that is the head one for Oregan, and he is going to get fired because he says the climate is changing as part of a natrual progression for earth. According to the GOvenor of Oregan that doesn't line up with the way that he wants that state to function. This is ALL political. China produces more harmful emmisions from their country wide coal burning that would take 2 billion SUV's to duplicate, and I believe that currently there are only a few million in the world. And funny enough China is exempt from the Keuoto (sp?) Treaty. In the treaty if you want to polute more then you have to buy "Credits" from other countries to do so. It is all about shifting wealth. This is so sad that the serioulsy flawed science behind it. Anybody who believes in global warming is a lemming. THe LIberal Media is pushing forward Thier radical agenda whether there is sound facts or not. THere are more credible scientists who do not believe that global warming is caused my man. ANd when I say global warming I am saying that the earth has raised .6 degrees celcius in the past 125 years. This is all about the grant money and the tearing down of America. WAKE UP AMERICANS

Certain gases don't let the heat escape from the Earth's surface. It's like putting on an extra blanket or an extra sweater. If you put on a sweater, the sweater does not actually make any heat. It just makes it so that the heat from your body does not escape as easily.
The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. (The higher ends of the ranges quoted are for the gas alone; the lower ends, for the gas counting overlaps.)[2][3] Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons (see IPCC list of greenhouse gases).
Millions of tons of crap DAILY into the atmosphere is nothing to sneeze at. Pun intended.
We are shrewing ourselves over for a buck.
Shooting ourselves in the herd.
Stepping on our own ducks.
Cutting off our nose to spite our finch.
Kicking ourselves in the asparagus beetle.
For the almighty dollar we're ruining it for everybody and everything, and people who deny it are three fries short of a Happy Meal.
Have a nice day.

How about visiting your local library instead of asking people to do your homework? Just because an assignment is challenging doesn't mean it is "stupid."
There is no shortage of material available (including online databases) at your library. Learn how to use it instead of simply relying on others to do your work for you. Librarians are happy to help students learn how to use the various resources in a library.
And while you're there, maybe you can pick up a dictionary and a book on English grammar.
You might think that people like me and your teacher are jerks - but if you don't learn how to do research on your own, you will not have the tools necessary to lead a rewarding life later on. School might be tough now, but it's NOTHING compared to what you'll face when you're an adult.
Good luck.

Here is the basic information. And some good quotes, too.
Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing.
Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.
It won't be a Hollywood style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.
Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.
"The science of global warming is clear. We know enough to act now. We must act now."
James Rogers, CEO of Charlotte-based Duke Energy.
"The overwhelming majority of atmospheric scientists around the world and our own National Academy of Sciences are in essential agreement on the facts of global warming and the significant contribution of human activity to that trend."
Russell E. Train, former environmental official under Presidents Nixon and Ford
"Global warming is already starting, and there's going to be more of it. I think there is still time to deal with global warming, but we need to act soon. Humans now control global climate, for better or worse."
James Hansen, Ph.D. climate scientist, NASA
"By mid-century, millions more poor children around the world are likely to face displacement, malnourishment, disease and even starvation unless all countries take action now to slow global warming."
Michael Oppenheimer, professor of geosciences and international affairs at Princeton University
"We simply must do everything we can in our power to slow down global warming before it is too late. The science is clear. The global warming debate is over."
Arnold Schwarzenegger, Republican, Governor, California
"Our nation has both an obligation and self-interest in facing head-on the serious environmental, economic and national security threat posed by global warming."
John McCain, Republican, Senator, Arizona
"These technologies will help us become better stewards of the environment - and they will help us to confront the serious challenge of global climate change."
President George Bush

Increase in carbon dioxide (caused by burning coal, and other things) in the air = increase in temperature
Increase in temperature = can greatly affects orgamisms
That's what I remember from Earth Science class.
