A brief but comprehensive overview of what science knows and does not know about climate change at the start of 2009. Very interesting live presentation given by a leading climate scientist at the 25C3 Chaos Communication Conference in Berlin 2008-12-30. Language spoken: English Duration: 64 minutes Resolution: 720x576 Preview screens: http://bayimg.com/image/aanljaaba.jpg Speaker: Professor Stefan Rahmstorf (Potsdam Institute of Climate Impact Research) Excerpt: "... this [diagram] shows 400.000 years of climate change, and the blue curve is the up and down of the carbon dioxide consentration in the atmosphere as measured from ice cores from Antarctica, and the red curve here is the temperature in Antarctica from those ice cores. Many of you will probably recognize this, because this is the point where Al Gore in his movie climbs on a ladder, and... he makes a slight mistake there... Otherwice it is a quite good movie, but this story he does not get quite right. So, what I want to tell you about this data is mainly two things, the first of them is ..." ________________________________________________________________________________ Please help seeding this torrent after downloading to make it available to more people.
A note: Since this is a recording of a live presentation at a conference there is a small problem with the sound quality at the start of the live presentation but they get it fixed quickly and the sound is good from then on.
In case anyone with an old computer has problems playing the movie you can try changing the end of the filename from .mp4 to .mpg or to .avi

Cheers m8, looking forward to watching this
This is a must watch presentation. Thanks for the up! Oh and yes Global Warming is real!
So is global cooling. Its the sun. Plain and simple.
@Ocarinar
The process of climate change (whether it be warming or cooling) is more composite than just the energy influx from the sun.
This presentation gives some insight into how the different physical factors are interconnected and on what grounds scientists make their projection scenarios.
No matter if you are "for" or "against" climate change I think you will find this interesting to watch. The speaker tries to answer several critical questions from the audience (consisting of non-environmentalist computer hackers) after his presentation is finished.

Thanks for uploading that =)
so is carbon-dioxide responsible for the melting of the polar ice caps on mars? the melting of ice on saturns and jupiters moons?
gonna watch this film though folx.
information can't hurt me.

it can if your religious! lol
if you learn enough science there is no way you can keep your faith
*grin*

How in the world did they collect data from 400,000 years ago. Amazing. If we had only known when they first started collecting! What a bunch of hogwash. First Global warming, but now, cause it's cooler, it's "Climate Change". "Lies always change but truth remains the same"-ME
Garbage, the sun is the cause of this stuff. Periods of warmer temps and cooler. Watch the great global warming swindle up on here. Sad a british news agency reports on it but here in the states oh better believe gore or you are a holocaust denier as they say in the movie

exelent presentation, plus it explains/debunks a couple of "skeptics" arguments. well worth watching.
THANKS CCC !

I haven't seen this yet, but for all you luddites burying your head in the sand, please tell me at what point before the modern industrial revolution were humans releasing enormous quantities of carbon monoxide (among others) into the atmosphere. If you don't think that makes a difference - "oh, it's all the sun, man" - then you're scared to admit the truth.
The Earth might have a tough, resiliant and adaptive ecosystem but it can't last forever. Like an alcoholics liver, it will recover itself and recover itself after serious abuse, then one day it'll fail. It's not invincible.

The 'fingerprint' that shows the warming is absolutely NOT from the sun was discovered decades ago, from looking at the stratosphere/troposphere - if it was the sun, the results would be exactly opposite.
It couldn't be clearer, but still 'It's the sun' returns as an argument. Why? Because 'sceptics' are shameless chancers, re-animating 'zombie arguments' if they think they will work. They can even contradict themselves completely, so they have no consistent internal logic, that's no problem. That alone should tell you this selective scepticism is politics, not science!

Go to Dubai, where the Sheik is using his oil income to rapidly turning a mere 60km of coast into 800km of luxury beach front living. There is little provision for sea rise. Is he lying to himself? Should he read Anna’s book urgently? Similarly with the many new billion dollar airports at sea level around the world and the explosion in interest in river front and beach front living. You can only think the world’s developers, engineers and investors with the best advice are completely barking mad and irresponsible spending trillions building at sea level or they do not believe there is going to be any significant sea rise in the next fifty years. Even the sinking Maldives are building new airports at sea level, possibly as they lack land let alone hills. Clearly they are all mad, deceived by a campaign of disinformation by vested big money oil interests.
So that's your evidence? Inference from developers/real estate agents?? How many times have unsuitable projects been built? How worried do you think developers will be about the next generation of owners, compared with the first??
As for the airports, you answered that yourself, but in economic terms, it may well be worth it for 50yrs of aviation use. Did you consider that? Please do yourself a favour and forget this ridiculous conspiracy theory...
