Definitely worth the watch. But... skip all the comments and video responses. Just the same typical bullshit of See no evil, hear no evil, speak no evil.
Anyone know who this guy is? I haven't done any searches or tried looking at YouTube profile yet though. The whole thing was very well scripted and delivered. Very charismatic and watchable even though we're not looking at much more than a guy in front of a camera with a white board.

It's a logical argument that seems (and is) obvious. It's rather an alternate version of my argument, which is that even if global warming is not true, the actions we would take to combat it are still positive actions.
That is, even if global climate change is not true, it still makes sense to reduce our energy consumption, and it still makes sense to search for alternative fuels. For one thing, it's is an undeniable fact that fossil fuels are a finite resource. So are nuclear fuels, for that matter. The only infinite source of energy we have is the sun. (Yes, it's not infinite, but if it goes away, so do we, without question.) If you only had five dollars to your name, would you choose to spend it like a drunken sailor, or would you try to make it last as long as possible?
The counterargument to him is that he's ignoring the costs in the two positive scenarios. That is, if we do nothing and don't need to, there's no cost. If we do something and do need to, there's still a significant amount of cost. As such, you can't ignore the ramifications of those two scenarios, since they have different outcomes.
However, you still come up with three scenarios that we've dealt with and overcome before, and one cataclysm.

Like atoms/matter, money/wealth cannot be destroyed. It can only be redistributed. For one group of people to go into a serious economic depression, there will be others doing extremely well. I believe the economic burden can more easily be managed than the technical if enough thought is put into it.
I still can't believe that some people have such a negative reaction toward those who seek to help this planet and its inhabitants.

Well, that's part of my problem. We're not helping the planet. There's very little we could do that would harm the planet. We're talking about protecting our futures. Even if one isn't interested in saving the plants and animals, one has to realize that without those plants and animals, we can't survive.

Perhaps just a picky point, but wealth can be destroyed and is destroyed all the time. The obvious example is destruction of infrastructure in war. Sure, that can be rebuilt, and sure the rebuilders will be compensated, but real wealth has been lost; those rebuilding it could have been working on something new. Natural disasters destroy wealth. While a depression may affect populations unevenly, it is NOT correct to assume that one group's losses are another's gain.
The idea that wealth is a constant and can only be redistributed is the core mistake of modern "soft socialism". There isn't a pie of a fixed size that gets divided either "fairly" or "unfairly". Wealth is *created* by human effort, and can be destroyed by negligence (or worse). Part of the cause of this confusion is that most people equate money and wealth, and they are very different things.
The reason why some say that if you distributed the wealth equally around the world it would end up right back in the hands of those who have it now is not, for the most part, that wealthy people have learned how to very effectively screw everyone else. Its that, in general, wealthy people have learned how to create wealth (or manage the creation of wealth). Of course there are some exploitive ways to acquire *money* that don't involve creating *wealth*, but those are the exception. There are also people who would create wealth but lack any sort of means. Those things are true, but the idea of a fixed amount of wealth that gets shuffled around is a horribly mistaken idea, and the conclusions that are frequently drawn from it are very dangerous.

How do you explain the current crisis in the credit industry that happened because the value of credit lines backed by assests, such as houses mysteriously went down in value. You could argue that it wasn't really "mysterious" and that anyone should have seen the subprime crisis coming, but apparently Wall Street wasn't reading all of the hundreds of housing bubble blogs created in the last few years..

I disagree with this assertion. The qntm guy missed the point altogether. It is not about destroying the earth itself, it is about making it inhabitable. Namely altering the atmosphere.
The main thing that we can affect is the atmosphere. We already know that in the early years of the earth, there was no atmosphere to speak of and that is was generally made by the many colonies of bacteria that emitted oxygen. The beings on earth can certainly affect this. Now we are emitting other things that cause an effect. We have never seen the effect of this before so we will spend alot of time arguing about it.
But we can know more by studying the atmospheres on other planets like Mars and Venus. Both very different atmospheres. We have evidence that Mars once had rivers and that water was there. But that all changed for some reason.
So far in our search, we have not quite found a planet like ours - that could support life like ours. I bet that this has something to do with a proper balance being attained here. I would also bet that the kind of equilibrium we have here is hard to come by. If we frustrate it too much, we could be in danger of a serious global change.
We have had changes like this before - like the dinosours dying just from a meteor or something. We have evidence of cataclismic events that chanegd everything on the face of the earth and changed the course of the species. I don't doubt for one minute that with our technology, we could make very significant changes that could have very long term effects.

I have a few problems with the whole global warming thing, but not the problems you're thinking I might have after you've read the first inflammatory phrase of this sentence.  First and foremost, I think the assertions of problems caused by global warming may be greatly understated. Rising ocean temperatures spawning more frequent and more violent hurricanes. Rising sea levels wiping out coastal cities. Desertification of croplands causing worldwide famine. Worldwide famine causing mass migrations. Mass migrations causing wars. BFD. I want you to give some consideration to the first of the doomsday problems mentioned above: rising ocean temperatures. Does anybody know how great a temperature increase the algae in the ocean can tolerate? Is it important that the algae in the oceans are responsible for more than three quarters of the world's oxygen production? How about the nay-sayers who state (quite possibly correctly) that human activity is responsible for only three percent of the world's greenhouse gases, so how can that have much effect on the climate? Well, imagine a bucket with a hose feeding water into it, and a hole in the bottom of the bucket that leaks water out at exactly the same rate the hose fills it. Now, increase the output of the hose by three percent and see what happens. Have you noticed that the people who most vehemently deny that global warming is going to be a big problem are those who have a financial interest in maintaining the status quo? I'm kinda glad that I'm old and won't live long enough to see humanity reap the bitter harvest of its greed. The rest of you "youngsters" may not be so lucky. tanstaafl.

Most predictions of global climate change catastrophe feel that what's likely to happen is that Greenland will melt, dumping huge amounts of water into the Atlantic. I cannot help but believe that that water will most likely be only slightly warmer than freezing, and therefore couldn't do anything but cool the oceans. On the other hand, that water is likely to be freshwater, and therefore potentially warmer than the saltwater it would be flowing into, so I could be wrong.

Ahh.. so my drinks will stay cooler if I pre-melt the ice cubes before dumping them into the glass? Hardly.
That big ice-cube, Greenland, is already in the oceans, and it is already melting (I've seen it with my own eyes from above). This means that the ocean is warming up enough to melt it, *quickly*. This isn't making the ocean any cooler than it was with the ice form of Greenland in it.
Once it finishes melting, there'll be no more ice, and the drink (ocean) will get even warmer, even more quickly.
The global warming impact predictions are wayyyy understated.
Doh.

Really? The reason that the glaciers are receding from inland Greenland is because the ocean is sneaking over there and melting it?
The point is that it's the air temperatures that is melting glaciers. If the glaciers slide away more quickly, cold water will enter the ocean at a much quicker rate.
So yes, if you put a liter of 33°F water in your ten liters of 60°F water it'll cool down faster than if you put one ten mL 31°F ice cube in every ten minutes.

Every global climate change prediction I've seen shows the oceans heating at a far slower rate than landmasses, like 0-2 degrees versus 5-8 degrees, with the least amount of heating just south of Greenland.
I'm not an expert on either climate change or algae environmental requirements, but the oceans seem not likely to change much very fast, whereas the land temperatures are far more significant.

I recall a Discovery or History Channel show that stated the influx of freshwater from the melted polar caps would have dramatic (and difficult to model) effects on the undersea 'rivers' and their very existence. Halting the flow of water around the Earth would be far worse than the flooding that would come from the increased volume of water.
It was an interesting show. Sorry I don't have a better grasp of the implications or functional factors for you.
Another thing I recall was a google-maps based webpage that would 'flood' areas in view based on % melt. That was also interesting.

I saw the show you are referring to. What they claim would happen is the icebergs/ice caps would melt. That would decrease the salinitiy of the ocean. The decreased salinity would then cause the 'converyor belt' effect of the oceans, which cause the gulf stream to recirculate, to either slow down, or stop altogether. This recirculation helps to moderate temperatures around the globe (in conjunction with the prevailing winds) and dicking with it would cause the temperatures to go all out of whack.
That was the scientific conclusion, anyway.

I just noticed in a copy of The Skeptical Inquirer (a publication of The Center for Inquiry) which has this position paper that outlines the scientific evidence of global warming and possible scenarios. I haven't read the article completely, but I've never heard anything bad about the source and the article seems a fair assessment of the situation. Tim- the 'conveyor belt' is mentioned, also. Thanks!

That big ice-cube, Greenland, is already in the oceans, and it is already melting (I've seen it with my own eyes from above). This means that the ocean is warming up enough to melt it, *quickly*.
Well, kinda-sort of. The way I understand it (and I'm not a climate scientist, but I do read National Geographic, and they had an article on the Greenland glaciers last year), Greenland isn't really "in the oceans." The glaciers are actually sitting on land, and though the ends of them do overhang, or sit in the ocean, it's not the ocean that's warming up the glacier, causing it to melt. The melting is due to the rising air temperatures.
However, that melt water has two effects, which exacerbate the problem. First, it pools on the surface, creating darker spots that capture the sun's energy better than the surrounding ice (which reflects the sun's rays), increasing the temperature of the "melt pool". That, of course, further increases the rate of melting, in a feedback loop. Second, at some point, those pools either create, or drain into, a crevasse leading underneath the glacier. There, the water acts as a lubricant between the ice and the land, increasing the rate at which the glacier slides, which, naturally is into the ocean.
The warm ocean problem is not so much evident in Greenland's glaciers, as it is in the open Arctic, where ice no longer forms where it used to, and, when it does, it's neither as strong, nor as long lasting, as it was in the past. <insert picture of drowned polar bear here>

No one in this discussion seems to be grasping the fact that the Earth's oceans and atmosphere are inexorably linked. As goes one, so goes the other. The oceans are a buffer in the climate cycle, and even a small change in overall ocean temperature indicates something is wrong with our climate.

So what you meant to say before, is not that the melt water will "cool the ocean", so much as the melt water will decrease the rate at which the local ocean water temperature is increasing. It's still warming up, but, due to the influx of glacier melt, not at the same rate as it might otherwise be increasing.

Well, yes, we (or at least I) understand that, but that particular thread of the discussion was about a local effect, rather than the entire ecosphere cycle. Mark's statement (whether intended, or not, and he can correct me as necessary) had the implication that the warming ocean is directly causing the glaciers to melt. It's an indirect link -- the warming ocean contributes to the warming atmosphere, and it's the warming air causing the melting glaciers. Furthermore, one could argue that it's the warming atmosphere that triggered the ocean's warming, too, starting the feedback loop that we're currently in.
The melting glaciers are merely(*) a symptom of the problem that is most significantly manifested as a result of the warming air portion of the feedback loop, rather than the warming ocean part of that same loop.
(*) Okay... not "merely" -- the melting of the glaciers does have some contribution to the warming/cooling, but the real concern over their melt has more to do with a catastrophic rise in ocean levels, rather than contributing to increased heating.
All IMHO, of course.

Hm. What does rising ocean levels mean to river levels? I'm guessing nothing other than the mouth will be further, um, inland(?), but I'm not sure.

Hm. What does rising ocean levels mean to river levels? I'm guessing nothing other than the mouth will be further, um, inland(?), but I'm not sure.
It's probably negligible (and I'm making this up as I go along), but a bigger surface area could mean more evaporation, and more rainfall, leading to higher river levels over the whole catchment area.

I spotted that too, the happy face on the right column means "everything's ok" but on the left column the at the bottom is not comparable - it's the same as above, but no global warming.
He does talk about the options in some detail, but the table is the key point of the video, and making it so misleading is a bit wrong.

Oh, another argument is that there aren't just the two states, one where global warming doesn't exist and another where it does. There are really three states, one where global warming doesn't exist, one where global warming does exist and we can do something about it, and one where global warming does exist and we can't do anything about it. That third state isn't necessarily excluded when you narrow the question (as he did) to human-caused global warming, as it's possible that we've set something in motion that we can't stop.
So that adds a third row where not doing anything results in catastrophe and doing something results in a potentially worse catastrophe by exacerbating a fiscal depression.
Of course, there are potentially more columns, too. Doing something can be split into reversing/preventing/ameliorating global warming (which each could potentially be their own column) and preparing for global warming; that is, maybe there's some way we could allow global warming to occur but figure out a way to make it non-catastrophic.
Then each of the do-something columns can be split in two: one where we do something and succeed and another where we do something and fail.
All in all, I tend to agree with his conclusion, though. If we assume there is potential for catastrophe, we should do everything we can to prevent it.

The one thing I haven't figured out is how the cost of attempting to prevent global warming could cause a global depression. After all, that money won't just go away -- it's going to have to be spent researching, investing in, and manufacturing of new technology, and infrastructure, all of which should lead to more jobs, and a healthier economy -- making column A a win:win column.

I'm no expert on economics, but that money has to come from somewhere. Taxes. MUCH higher taxes.
And the problem with that, is the same as we have now, except greatly amplified: it only works if all countries participate. Without large economy naysayers like China, USA, and Russia on board, the countries that *do* participate will be at a severe economic disadvantage to those who don't raise taxation/participation levels.
In the end, everyone gets gradually fried.

Yes, basically you're pumping money into something that isn't immediately producing a salable product, and probably never will, as the only logical course of action is to give that product away, since it's probably useless if not applied universally. (Yes, people will make money implementing it, but they will be getting that IP for free.)
Of course, you're paying people to do these things, and employing people is positive, so it's not as if it's all going to waste, but there is no advancement of wealth.

O-kaaayyy... Let's start by assuming that the only way to ameliorate the global warming problem will be a drastic reduction in the consumption of fossil fuels. That means you get to drive your car 15 miles per week. That means that the availability and cost of manufactured goods goes up enormously due to chaos in the transportation industry. That means that the world's largest industry (no, not automobile manufacturing, which will also be destroyed, but, believe it or not, tourism) will go away. That means a tremendous change in the entire social fabric (in the USA at least and in many of the so-called developed countries) as even getting to work on a daily basis will become problematical if not impossible.
The above effects are just the tip of the iceberg, so to speak, and would certainly be the harbingers of a global depression.
Just call me Mr. Gloom & Doom, but I honestly believe that we are already past the tipping point.

I once saw an office block in a US city that had bicycle racks outside. Then I looked a bit closer. It was the EPA office.
A 15-mile-per-week private car rationing scheme would certainly radically change the pricing structure of the housing market (McMansions in gated communities far from public transport links would be worthless, run-down townhouses near rail stations in inner suburbs would be very valuable). But if the change were gradual enough, I don't see that it would damage the economy too much, at least if commercial transport was affected less.
It would be a "tremendous change" in the lifestyles of those people who do currently have 10-mile, 30-mile, 50-mile car commutes. But the writing has been on the wall for that lifestyle for a long time. Are there really still people who believe it will continue to be sustainable indefinitely?

Right. And just how much time do you think we have?
Think about how long it would take to essentially shut down the automobile industry and all the peripherally related industries (steel, rubber, automobile repair, auto sales, etc.) and re-employ those workers, without triggering a global depression.
Hey, maybe we can convert over to building ELECTRIC cars, and get around the whole fossil fuel thing and save the world. Oh, wait... where is the electricity to run the electric cars going to come from? Coal? That would be worse than burning gasoline. I know! We'll build more nuclear plants. The average waiting time for certification of a nuclear power plant in North America is currently around 40 years and counting, but what the heck, maybe the ice in Greenland won't melt all that much in another half a century.
The automobile industry is just ONE example of the turmoil that would ensue in the unlikely circumstance that we actually did do something about global warming.

Apparently the 59,297 Americans who purchased large SUVs in April alone of this year seem to think so. (Scroll to end of article for citation)
There's the myth of an old Chinese curse, "May you live in interesting times." The coming decades certainly have my interest.
