Just finished watching the documentary/movie was well worth it. Some pretty scary 'real' sceniaros that mirror 'the day after tommorro' however instead of a few weeks we are looking at a decade or two for the 'ice age'

there is nothing to disput global warming and the very real dangers already today.

There is stuff to dispute whether or not the global warming is manmande - that's where most of the debate is.

We just need to get rid of cattle. If they weren't producing all that methane, we'd be a lot better off.

I don't think you'll have a doubt in your mind after watching the docu/movie

LOL, cow burping was the 'ozone' conflict wasn't it?

After a few years worth of working towards a double-major in international political science and economics, propaganda films are far less effectual than they used to be, be they from the right, left, up, or down. I've researched the global warming phenomenon and found that the scientific establishment has not established the cause of recent global warming. Nevermind the fact that people often use doomsday scenarios to scare people into backing a given cause. To say nothing of the fact that meteorologists often can't even get the weather forcast a week out correct, so why should I trust these weather forcasts decades or centuries out?

I won't do the docu/movie any justice, however there was crediable evidence global warming is real. The movie also cited' the scientific establisment in peer to peer notes of over 900 none of them disagreed on the global warming issue.

The comparison of Co2 levels in relationship with tempurature was presented objectivly, the levels were real, and the tempuratures were real. The cause of the emissions was left for the audience, however it does not take a giant leap of faith to make the connections.

There was also evidence etracted from ice cores, relating the tempuratures of the last 600,000 years. For over 600,000 years the average tempurature of the globe has never reached its current levels, and once more, the average tempuratures of the planet of over 600,000 years showed the differnece between sitting in america on an average sunny day, and having over 1 mile of ice over your head. To show the current tempuratures spanning 600,000 years he literally had to use a 'lift' to raise himself over 15 feet, where the largest fluctuation hand been only a few feet between ice age and the hottest years.

I'm not saying that global warming isn't real. What is ultimately at issue is how much of it is due to human activity and just how dire the results will actually be. Please have a look at this presentation created by Richard Lindzen, Alfred P. Sloan Professor of Atmospheric Sciences at MIT:

Al Gore.... I'm trying to think of a joke about a lock box... because it would be so timley...

Try this.. put some ice in a bowl Fill the bowl up with water until it's almost overflowing. Make sure that the ice is simply floating in the bowl. Alow the ice to melt. Will the water overflow the bowl?

ice not floating I beleive was the demonstration, like the ice on greenland

he dependence of the temperature on the CO2 concentration is not linear but rather "sublinear"

I'll have to watch the movie again. there was a direct relationship between the two, however, it this statment is true, the rizing of both co2 and tempurature should have been gradually getting closer. The idea is that co2 in the atmosphere also protects more radiation from making it to the earths surface... However this is still not healthy and only covers 'tempurature' less natural light will have an effect on plant life which is the natural 'scrubber' of Co2

Without getting into too many details(for now, not enough time ), I will say that I think people tend to polarize this issue, one side overpromoting it's danger or the other underpromoting its danger. It is obviously a very complicated situation, one that is based not on a few big factors(though we'd love it if it was) as much as a lot of small factors that act as forces on the ecosystem, and as our understanding isn't solid enough to put comprehensive mathematics behind it and really predict (& therefor test) theories very well, it is hard to find the cause and the effect. However, you would be surprised how much information there is out there, ever increasing exponentially since 2000 it seems, to the point where there is too much evidence to deny that humans are in some part playing a role, particularly the role industrialization has had on the ecosystem of the planet. (Including our re-evaluation of the ecosystem during the 80's when 'global cooling' was confusing the data and justifying arguements against man-induced global warming). One piece of evidence that pushes it over the edge for me is CO2 levels at atleast 2000 years out:

The last link Stasi provided is rather old, a lot of important discoveries have happened since 2000, here is the new "In Depth" section from the BBC:

Mmmmhmmmm, but the content really isn't much different than that in the links with more recent data I provided.
