Yeah. Don't cause it.
Serious, start with what it is and what causes it. Include things like hole in the ozone layer and such. Close out with positive efforts. Include the Kyoto Pact.
Why is it that the biggest greenhouse gas emission country (USA) refuse to sign a pact that requires a reduction in the emmission of greenhouse gases. And why do its politicians claim that more studies are needed to determine whether or not these gases really causes ozone depletion?

How do you know there is globing warming? Have similiar things happened in past? Not in our life time but in the earth's past. At one time the whole inland plains of the U.S. was covered with water. During another period the same area was covered in ice! The ocean levels today are higher than they were a few thousand years ago. The fossil evidence indicates that northern Alaska and even the South Pole had very temperate climates at one time. The last "mini ice age" in north America ended about 1840! What causes Ice Ages anyway?
The problem with "golbal warming", as I see it, is that too many people are making guesses based on geological very, very, very short term 'evidence' that cannot explain past earth cycles.
Wolly Mammoths have be found frozen in Siberia with buttercups in their mouths - how did that happen? Today's alarmists cannot explain the long period cycles of the planet but keep yelling "global warming" - based not on thousands or hundreds of years of research but just a few years. Why was there a great inland sea in this country, why did the ice damn holding Lake Missoula melt and flood the entire Columbia River basin?
Based on most estimates, the planet earth has been around for about 4 billions years, alot of those years without even oxygen in the atmosphere! All the continents were together for one land mass! Obviously there have been some changes.
Until science can explain most of the previous cycles of the earth's atmosphere, a current 'snap shot look' does not prove global warming or any other radical change in the earth.

First choose if your going to say it's happening and needs to be recognized and halted, or if it's just a change in nature which has always and will always happen. After that get the facts to support the point of view your trying to push and throw in some big words.
Also I heard that northern California is suing a bunch a of automotive companies for global warming lol.

thats easy, i did a report on it last year except it was a hard thing to get info on. I say that u should approach it by: Global warming is caused by a vast list of causes. One of the most popular cause is the greenhouse effect.
