An Inconvenient Truth Trailer

Yes I think its just a period of time thats getting hotter.
I think the Earth just does this sometimes like the ice age.

i watched this in science class it is amazing i almost cried when i watched it! if you wanna learn more watch 6 degrees could change the world! we should all prevent global warming from happening!

Thermal Maximum. This was 55 million years ago. 55 million years ago, palm trees existed as far north as the southern tip of alaska as far east as wyoming. Species of alligator were discovered in Canada's yukon territory. There was no glacial ice. There was no permanent ice on the entire planet. 55 million years ago, Earth was indeed a different planet. The current level of carbon dioxide in our atmosphere is 750 ppm. During the PETM, it was 1200. We're expected to reach in that 50 years.

the earth is in a perpetual cycle of heating and cooling periods. The event of a "global warming" or cooling spell is 100% normal, this is true. It is also true, as scientists have proved, that the amount of carbon dioxide and global temperatures are more or less a direct cause, with a few other minor influences (methane, a substance stored in large quantities of arctic ice, being one).The last warming period whose temps equaled the ones we're experiencing was called the Paleo-eocene Thermal Max

this is the most terrifying video i ever saw.
did we really betrayed earth or earth betrayed us?.....?????????

Please watch my video and see with your own eyes; Go to punchpringle1 and click on my first video: 'Video Proof of Global Warming!'
(very short video)

For crying out loud. A large participant is this phenomenon is the sunspots and the overall heating of the sun itself. BUT WAIT--there's no cars on the sun, are there?
Observations of these same things on Mars and Jupiter--but there's not cars on there either! Imagine that!

GlobalWarmng is due tothe planetary orbit of Nibiru the 12th planet that is on its way back and will reach its 0 point on dec. 21th 2012. On one of the satellite planets that orbits Nibiru, lives a superior race of beings known as the Annunaki, who are a race of giants

The truth will set you free

Have you noticed, for example, how every heat wave results in more media hysteria, while record cold waves are brushed aside as irrelevant?

Global warming has already started. It's been taking place for years now. We're slowly, but surely, killing our planet, and in doing so, ourselves.

wrong, global warming happened before causing massive extinction of animals and plants, the problem is that it happened more or less gradually and only survived the ones that could addapt, the real problem of global warming caused by mankind is that it's too fast in time.

the whole point of this film is IF we don't do something about it then the earth won't be like it is today but douche bags like yourself pick on stupid things like that. who else besides al gore do you know that travels the world explaining the danger that can happen? no one. so think about what you say before saying it. peace.

hey i wouldnt have to got to school cuz it would be underwater ^^!!! lol but its in 100 years :-S

Holy S**t Calcutta will be in under water

really? is this truth, y don't you give some facts to back that statement up?

this is really scary
we should stop global warming before it starts

this is truth!

Anyone that has seen this film surely noticed how many times this hypocrite says the word "if". If this, if that, if greenland were to split in half then the earth's sea level would rise 20 feet, ya...IF!!!...maybe IF Al Gore wasnt such a douche bag hypocrite he would not be traveling the world in his gulf stream and "F**king up our global temperature"

btw global warning never happend before just the ice age

skeptics the truth is right there glaciers disapearing ocean risings temperature increase worse storms, this is one of the biggest issues in the history of mankind.

Same here. Im glad she did

The rest is natural? Greenhouse gases make the atmesphere thick. Sunlight cant escape; world heeats up. how is factories releasing Co2 and fumes from cars natural, huh? HUMANS CAUSED GLOBAL WARMING, SO WE ARE THE ONES THAT CAN STOP IT
