An Inconvenient Truth
There's a movie teaser line that you may have seen recently, that goes like this: "What if you had to tell someone the most important thing in the world, but you knew they'd never believe you?" The answer is "I'd try." The teaser's actually for another movie, but that's the story that's told in the documentary "An Inconvenient Truth": it starts with a man who, after talking with scientists and senators, can't get anyone to listen to what he thinks is the most important thing in the world. It comes out on DVD today.
The scariest horror film of 2006 was a documentary.
The first thing everyone wants to know, or at least to argue about, is whether Al Gore has his facts straight. The short answer is yes, he does. There are minor errors. They don't detract from Gore's main point, on which the scientific debate has ended.
And the main point is scary, and almost too big to think about or talk about. The earth is warming, because of us. Sometime in the next hundred years, our environment is going to change in big ways. We can't predict it with much accuracy yet, but the best estimates we have are that it's going to be -- measured in lives and dollars -- really bad.
In a way this film isn't really about that story. It's about a man telling that story -- someone who, after suffering a bit of a setback, asked himself, well, what can I do now? What's important to me? How do I want to spend my time?
What's important is a question a lot of nerds may be familiar with. We like to talk about important things. But how do you respond when you try to say something serious and the cool kids laugh at you? What do you do, when you put yourself out there, try to engage people's minds, and instead they make fun of your clothes?
The good news for anyone who's had a prom invitation rejected is that people can come back from worse disasters. His presidential bid didn't go so well in 2000. Gore had given talks on global warming before; after he was forcibly retired from public service, he took a Powerbook and Keynote on the road, sharpening and expanding his slideshow talk in airports and hotels.
Half of the film is that talk, and it's an engrossing talk. There are charts and diagrams and footnoted stats (and a Futurama clip) and it's about as fun as numbers and chemicals get. Turns out Al Gore has a sly sense of humor (but not a nasty one -- the film's only two political nudges are pretty gentle). Unless you're a climate scientist you'll probably learn something too.
But the other half, interwoven with the lectures, is a man picking up the pieces and rediscovering something important in his life, a message that he has to tell. That succeeds as a film.
And Gore's lecture succeeded too. Somehow, I'm not sure how, this documentary changed the way Americans look at global warming. In early 2006, global warming was still seen as one of those things that may be true or may not. Pundits were fairly evenly divided and both positions were routinely heard. It's now late 2006 and the debate has moved from "is global warming happening?" to "it's happening, we've caused it, and what if anything should we do about it?"
Most of the warming-deniers left are the real extremists out in Rush Limbaugh territory. We're not yet all the way to a serious, scientifically-informed debate, but somehow, overnight, this film pulled most of the fence-sitters over to where the scientists were years ago.
As for actually fixing global warming, it will take a miracle. Maybe two miracles. I think in the next few decades we're going to need to start an Apollo moonshot-type miracle of technology and engineering to beat back the greenhouse effect. Nanorobots. Reflective dust in the stratosphere. Giant mirrors at the Lagrange point. Bioengineered plankton to sink carbon or change the oceans' albedo. Something. That's just a guess.
But meanwhile, though we hope someone can build us an airbag before we crash the car into the tree, that doesn't absolve us from stepping on the brakes. Right now, we need a change in attitude, in our community and our politics, to start slowing the damage we're doing every day to our grandchildren's Earth -- to buy them time, and give them more options. The only way that happens is when the governments of industrialized and developing nations decide this is a priority.
And the only way that happens is for people everywhere to stop listening to the cool kids and, once again, pay attention to the nerds.
I don't think the reason that nobody initially wanted to listen had to do with the story, but rather the storyteller. Gore was about as charming and captivating as an endangered sea turtle. Had some other high profile public figure attacked the problem with the same gusto, there may have been a little more initial acceptance of the core message, which I actually feel would have harmed the result.
... An Inconvenient Truth is one big step in the right direction.
Why? Because if anyone else had tried to get congress to act on Global Warming, there would have never been An Inconvenient Truth. Had Gore been more successful in convincing congress to join the Kyoto treaty or strengthen EPA guidelines, I don't believe there never would have been the movie. Which just means that the public would remain uncommitted/unconvinced, and future administrations would have just reversed what the more convincing version of an Al Gore could have achieved in Congress.
What's amazing is that Al Gore's movie really IS engrossing. He comes across as a man with a mission. While he may sensationalize the risk a little at times, he delivers a message that is irrefutable: we must act now. I believe he has helped increase awareness of the problem, and the greater the awareness the greater the chance for long term change. Governments will act on ridiculously expensive endeavours only in the face of overwhelming public support
Huh? Don't mind me, I'm just the new guy.

There are some conclusions that I think are inevitable... The final ultimate conclusions is essentially:
Nothing, absolutely nothing, says it can't be done with energy-farms on colossal areas. These farms are used for sequesteration and also as an energy source. This does not depend on changing human nature, it will work and it will pay itself of. All it needs is for someone to propagate the idea.
Runup to that conclusion:
Sadly recent news and statistics can let one only draw the following conclusions:

If you'd like to recreated a lot of the stuff from the movie, using real data as inputs and getting similar results as what Gore gets, the EdGCM project has wrapped a NASA global climate model (GCM) in a GUI (OS X and Win). You can add CO2, re-arrange the continents, change the vegetation cover, or turn the sun down by a few percent all with a checkbox and a slider. Supercomputers and advanced FORTRAN programmers are no longer necessary to run your own GCM. Disclaimer: I'm the project developer.

The short answer is, you don't look at scientific consensus as proof, but as evidence for forming your own conclusion. The caliber of people that hold an opinion are testimony as to it's potential worth. When a bunch of religious nutbars, tin foil hat conspiracy theorists, and oil industry executives hold one side of the opinion, and a wide collection of highly educated, fairly disinterested parties hold the other, I'm inclined to give the nod to the group that actually studies the issue and knows how to work numbers. The fact that the educated group also has data to support their views, while the rejectors mostly proclaim, like Monty Python's knight, "It's not proved yet!" is merely icing on the cake.
I was taught to respect my elders. The trouble is, it's getting harder and harder to find some.
Even a devout Catholic can't look at the history of the Catholic church and say that organized religion has been anything other than a monstrosity for most of its history. From the Inquisition to the Crusades to anti-Semitism to political and social oppression - the history of Catholicism is sordid and shameful. Most organized religions fare no better, and the shame of their history simply depends on how long they've been around. The Mormons, for example, have the Mountain Meadows Massacre (http://en.wikipedia.org/wiki/Mountain_Meadows_Mas sacre).
However, just as science has been misused to support things like phrenology (http://en.wikipedia.org/wiki/Phrenology) the argument can be made that what we've seen historically is not necessary to organized religion. It is instead what happens when organized religion falls prey to lust for political and economic power. As far as I'm concerned the chief difference between the evils of organized religion and the evils of science are that religion is a much, much older social institution than science. As a result, religion has had time to be perverted in all kinds of ways that science has not yet and - if we are vigilant - never will be.
In short: People who believe in organized religions should be the ones who are the angriest about what religious institutions have done throughout history. It's our duty to try and make sure the same mistakes of the past aren't committed again.
As far as my anti-authority stance goes, yes: there is a certain amount of intellectual tension in both adhering to a standardized body of theological belief and the scientific method. But tension is not the same thing as contradiction. I happen to think that part of the purpose of an organized religion is to make our intellectual lives harder - not easier. Intellectual tension is the motivator for intellectual growth in the same sense that necessity is the mother of invention. This means I don't hold my spiritual beliefs as sacrosanct and my scientific ones as conditional. All belief is conditional. I don't expect everyone to believe that, especially given religion's dearth of credibility on Slashdot, but that's the intro to the answer to how a devout Mormon also holds anti-authoritarian beliefs if you're curious.

How very true, and completely beside the point. Consensus is important because it is enough to justify action. The debate is not really about the "truth" of global warming, it is about the cost of preventative measures versus the cost of inaction for a range of possible scenarios. It is about risk assessment, it is about pinning down variables.
Which explains one of the controversial aspects of the movie: the apparently equal focus on Al Gore, the man.
One reviewer I read hit it on the head: this is a concert movie.
It helps that the concert turns out to be a surprisingly good one, but the film takes you not only backstage, but to the back story. There is a poignancy to watching the man who won the popular vote for US President in 2000 schlepping his stuff from venue to venue, telling the same story over and over. If you don't put a human face on his motivations, it would go from poignancy to pathos.
It's important for the movie not go there, because despite its dire message it is supposed to leave the viewer with hope and optimism.

This reminded me of something. I remember being scared to death when I was a kid (20 years ago) because I saw a news article that the o-zone may be completely gone in a 10 years!! Well, what the heck happened? I know there is still a big whole in the ozone but where is it now? The fear mongering media must have moved on.
.
I also remember in an early science class that we would be out of oil by 2015, but I saw a report recently that we wouldn't be hitting problems until 2050. Not that 2050 is good either, but I just do not respond well to this "SKY IS FALLING" attitude anymore.
My favorite argument for global warning I've heard is "Even though we can't prove it 100%, the consequences are so grave we should stop C02 emissions now!!" Well, I have a theory that I can't prove 100% that Aliens are going to invade the earth and grind us into sausages, and the only way to stop them would be to shroud the earth in a planet wide blanket so the earth can't be seen. I can't prove it, but DO YOU WANT TO BE GROUND INTO SAUSAGES?!?!.
I do believe that global warming COULD be a problem, but this is highly reminiscent of media fear mongering. Where are all those hurricanes we were going to have this year because of global warming?!
. The trouble is: how do we make up our minds about the issue if we reject scientific consensus as proof? The only thing I can think of is to understand as much of the issue as we can for ourselves rather than from the media. That's something I definitely need to work harder on.
It is far better to act on the basis of authority than not act at all. 98% of people do not have the ability or time to work through the equations and models themselves. Does this mean we should never act on environmental issues? If a parent is told that scientific consensus says that taking Thalidomide while pregnant will result in birth defects should the parent continue to take Thalidomide until they go back to school to study up on statistical methods and double blind tests?
When you go off and research the issue and come back to us with arguments that undermine the authorities then you have a right to tell us we're on the wrong path. But it is totally irresponsible for you to just wave your hands and say: "Don't believe the authorities! Don't act! Don't do anything until you've studied it yourself! I'm not studying it, but you should!" You're just parroting what the oil companies have been saying for the last decade. "In the absence of absolute proof, inaction is preferable."
In this case, there is one aspect which is totally undisputed. We are changing the atmosphere. Where I come from, pissing in the bathtub is considered impolite whether anyone is guaranteed to get sick from it or not. Human beings should minimize their impact on the atmosphere precisely because we do not know with certainty what the consequences are likely to be.
Out of the things I am passionate for, my support of nuclear fast breeder reactors (specifically speaking, the lead-cooled variety) and the development of such is probably at or near the top. Here's why.
Number one: INHERENTLY SAFE
Any commercial nuclear reactor anywhere in the continental US in this day and age is of the thermal type. To put it simply, this means that they operate using highly pressurized water as a coolant and as a moderator. The consequences of using such a reactor are that the water must be pressurized to the extent that it remains liquid while heated to somewhere around 200 degrees C higher then it's normal atmospheric boiling point.
Is this a good thing? Quite frankly, in my opinion, no. Chernobyl was what it was because when the folk operating the plant (a comparatively poor design to be sure) failed to keep the reactor under control, and the heat reached uncontrollable levels, the cooling water literally became a steam explosion, bursting the pipes and blowing a section of the plant apart. This radioactive "steam" then escaped and spread across much of eastern europe. The consequences of using such a design may not ever be fully known.
A fast reactor (as opposed to thermal) is of an entirely different design. A fast reactor does not need a moderator and typically uses a highly heat-conductive liquid (usually a metal with a very low melting point) to cool the reactor core. In most designs, the reactor core sits inside a large "pool" of such material and is cooled by natural convection, rather then traditional "fail-safe" mechanisms like pumps. In addition, the reactor core can be designed in such a way that basic physics prevents it from getting above a certain temperature. As the materials used in such a design expand, the amount of fission reactions actually decrease the hotter it gets. Meaning the hotter it gets, less heat gets generated. It's a natural check against any conceivable type of meltdown, without the need for human interference. In addition, no pressurization of any kind is needed. The entire plant can operate at normal atmospheric pressure. No steam explosions. If every single human being working at such a plant were to die, the fission reactions would die off naturally over time, the reactor would cool down to outside temperatures, and eventually become entombed in a huge chunk of shield material (if Lead or Lead-Bismuth is used as the cooling material). In effect, it's an entirely safe reactor design in every way that practically matters.
Number Two: MORE EFFICIENT
This actually means several different things. First off, and most striking, is that a breeder type of reactor can potentially get nearly a hundred times as much energy out of the already impressive energy potential of uranium ore used in traditional "thermal" reactor designs. This is because thermal reactor designs only "burn" about 1% of the uranium ore that gets put into them, which is Uranium 235. The rest of the Uranium 238 (far more common in nature) becomes highly radioactive and gets thrown away as "waste" that lasts a considerable amount of time before it goes back to the same level of radiation as the ground it came out of. A breeder reactor alleviates this problem by not only burning the usable Uranium 235, but by "breeding" an even greater amount of the Uranium 238 into new fuel, plutonium. The really ideal part is that if integral plant designs become common, the new fuel that gets bred in this process can be refined and put directly back into the reactor core, without the need to ever leave the site. Over time, all of the uranium that gets put into such a reactor gets used as fuel. This gives the human race enough potential energy, given the worlds known reserves of uranium, to last well over a million years. In addition, all that is left is leftover fission-products that have a much smaller frame of time to decay to safe levels then traditional waste, 300-400 years to be exact. And far less of it; small enough amounts to handle safely on site without problems. It can even be
I know this is an odd question, but has anyone considered the amount of heat our modern society produces? Lightbulbs, cell phones, cars, trains, airplanes, power plants--everything modern society relies on produces heat.
Might that heat--maybe combined with greenhouse gases--be contributing to recently noticed warming trends?
It's a documentary about Global Warming, not 'Our Earth: Greenhouse or God's Judgment?'.
This is science, it's not been proven or dis proven yet. But there is a scientific explanation for it, much like most of the other theories out there. (Evoloution, black holes...)
:3 rawr.
Actually, By the time Piltdown Man was revealed as a hoax, many anthropologists' models of human evolution were already regarding it as an aberration and disregarding it. I imagine quite a few of them blew sighs of relief when they heard it was a hoax. There were a few at the time of discovery believed it to be a hoax, too. I suppose time will tell on the global warming debate, too.
This is science
..... Sorry
Bwaahahahhahah Um
Science refers to either:* the scientific method - a process for evaluating empirical knowledge; or* the organized body of knowledge gained by this process.
en.wikipedia.org/wiki/Science
Ok now here is the challenge show me ONE of these studies you are talking about
much less read and understood that does not have fudge factors built into it and I will agree that you are approaching it from a scientific stand point not before. Every one that I am aware of has included some kind of fudge factor built into it.
Now on that note
Aceptance of ideals, beliefs, etc., which are not necessarily demonstrable through experimentation or reason.
