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, mostly caused by water vapor.
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.
Really good website for more information here:

Lots of numerical scientific data proving it real here:

Probably the best is the Union of Concerned Scientists because it is scientists from several nations and not just one nation stating an opinion although this site is the American branch of that.
the next site I give you here concerns what you, or anyone else for that matter, can do to reduce your carbon footprint and decrease global warming in that way. Good luck with the project!!

British Judge rules 11 wrong Facts Al Gore in Court
Inaccuracies in Al Gore's An Inconvenient Truth
The decision by the government to distribute Al Gore's film An Inconvenient Truth has been the subject of a legal action by New Party member Stewart Dimmock. Although a full ruling has yet to be given, the Court found that the film was misleading in 11 respects and that the Guidance Notes drafted by the Education Secretary’s advisors served only to exacerbate the political propaganda in the film.
In order for the film to be shown, the Government must first amend their Guidance Notes to Teachers to make clear that 1.) The Film is a political work and promotes only one side of the argument. 2.) If teachers present the Film without making this plain they may be in breach of section 406 of the Education Act 1996 and guilty of political indoctrination. 3.) Eleven inaccuracies have to be specifically drawn to the attention of school children.
The inaccuracies are:
* The film claims that melting snows on Mount Kilimanjaro evidence global warming. The Government’s expert was forced to concede that this is not correct.
* The film suggests that evidence from ice cores proves that rising CO2 causes temperature increases over 650,000 years. The Court found that the film was misleading: over that period the rises in CO2 lagged behind the temperature rises by 800-2000 years.
* The film uses emotive images of Hurricane Katrina and suggests that this has been caused by global warming. The Government’s expert had to accept that it was “not possible” to attribute one-off events to global warming.
* The film shows the drying up of Lake Chad and claims that this was caused by global warming. The Government’s expert had to accept that this was not the case.
* The film claims that a study showed that polar bears had drowned due to disappearing arctic ice. It turned out that Mr Gore had misread the study: in fact four polar bears drowned and this was because of a particularly violent storm.
* The film threatens that global warming could stop the Gulf Stream throwing Europe into an ice age: the Claimant’s evidence was that this was a scientific impossibility.
* The film blames global warming for species losses including coral reef bleaching. The Government could not find any evidence to support this claim.
* The film suggests that the Greenland ice covering could melt causing sea levels to rise dangerously. The evidence is that Greenland will not melt for millennia.
* The film suggests that the Antarctic ice covering is melting, the evidence was that it is in fact increasing.
* The film suggests that sea levels could rise by 7m causing the displacement of millions of people. In fact the evidence is that sea levels are expected to rise by about 40cm over the next hundred years and that there is no such threat of massive migration.
* The film claims that rising sea levels has caused the evacuation of certain Pacific islands to New Zealand. The Government are unable to substantiate this and the Court observed that this appears to be a false claim.
SO the ANSWER to YOUR QUESTION IS THEY WANT a CARBON TAX to tax evil OIL Corporations DEM Senator DODD. that means trickle down to you $8.00 a gallon Gas Higher food prices TRUCKS deliver food run on FUEL,higher electric they will build NUCLEAR POWER PLANTS its a low carbon foot print .
90% of France runs on Nuclear .SO the ANSWER to YOUR QUESTION IS THEY WANT a DODD. that means trickle down to you $8.00 a gallon Gas Higher food prices TRUCKS deliver food run on FUEL,higher electric they will build NUCLEAR POWER PLANTS its a low carbon foot print .Carbon Tax will go to build these also if you donate to Blue Sky thru power company the $ goes to build new nuclear plants they say its clean low carbon foot print,Be careful what we wish for
ANSWER: ask teachers What happen to the polar bears during the last 5 ICE AGES?.
What ended the Ice Ages?

Awesome, I'm also doing a project on it!!
I found the best sites:
www.uscusa.org/global_warming/
www.climatehotmap.org
World Book (G)
www.livescience.com/globalwarming/
livescience is probably the best because it gives you the most info, and more like the top 10 most polluted places, the ozone depletion by 30%, yea, that's about right, I hope you ace your project as i do mine!!!!!!!!!!!

lots of different persons have spoken approximately this. in fact, there is an advert on in Australia approximately it. curiously, cows (noticeably) produce a methane gas which contributes to a million/3 of our worldwide warming difficulty.
