Global Warming Irreversible, NOAA Scientist Finds
Tibor the Hun writes "NPR reports that Susan Solomon, one of the world's top climate scientists, finds in her new study that global warming is now irreversible. The study, published in the Proceedings of the National Academy of Sciences, concludes that even if we could immediately cease our impact on pollution and greenhouse gasses emissions, global climate change would continue for more than a thousand years. The reason is the saturation of oceans with carbon dioxide. Her study looked at the consequences of long-term effect in terms of sea-level rise and drought."
We all gona die, but at least I got my first post...
So they are saying we will have the opposite of the Younger Dryas no matter what we do. That may be true, and it might not be true, but I think it's a bit premature to say that our computer models are so good that they can definitively say what global conditions will be like in 1,000 years. Considering how few variables we model let alone the level of detail we have on those data points I think it's a bit foolish to say we can say much of anything definitive from our models at those type of timescales.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
Wow. I hope the paper is not as inane as her quotes. There's a difference between passive conservation and active geo-engineering. What Solomon is trying to say is that even if we all hold hands and try to conserve that it'll make no difference because the damage is already done. Of course, to acknowledge this is difficult if you buy into environmental conservationism, as Solomon obviously does, so you end up with quotes like "I guess if it's irreversible, to me it seems all the more reason you might want to do something about it".
How we know is more important than what we know.
Damn whales exhaling in our oceans.
Dad?
I am not surprised. I have been pondering the various, strong positive feedback loops involved with climatic phenomena, like the release of gigantic amounts of methane from the Siberian permafrost due to warming, the decrease of vitality and eventual death of plankton in the oceans (main source of oxygen for the planet, as well as main source of food for fish) due to increased sea temperatures, decrease of albedo due to melting of icecaps and glaciers, decrease of rainfall and consequent decrease of forests (that the Indonesian and Amazonian forests have been mercilessly burnt, doesn't help), to mention just a few. I am sure the better informed reader can add a few more of these positive feedback loops, but in my humble opinion, these are the stronger ones, and make the process of global warming unstoppable.

It's the old "Limits To Growth" bullshit back again. The same people who predicted mass starvation in the 70s are now predicting massive climate change. The whole concept that new technology means you can't just extrapolate seems to be lost on them.
And this kind of hysterics has been around a long time. Hobbes had his "nasty, brutish, and short" predictions for mankind in Leviathan. According to experts 30 years ago, the was simply no way we could produce enough food for 5 billion people. Now we're doing it for 7. These professional pessimists have always underestimated mankind's ability to change, adapt, and solve problems. They've always underestimated our capacity to make things happen.
Life is hard, and the world is cruel
The key element about global warming that seems relevant is this : how LONG will it take? If we have 200 years before the ice caps finish melting, then it's not really the crisis that it's made out to be.
Why won't it matter if it takes 200 years? Because realistically at even a fraction of the current rate of technological progress, mankind will have the technology to do something definitive about it in 200 years. The simplest, most elegant solution I can think of to global warming is to build giant orbital sunshades to reduce the total solar irradiance to the earth's surface.
I can even see how this would be done using a juiced version of current technology. Automated factories would produce the thousands of square kilometers of shade material (kind of like the automated factories in Japan right now...). The factories might be on the earth or the moon. We'd blast the shades into orbit using lasers (see Lockheed Martin's new LED pumped laser weapon for technology that could do the job TODAY) and they would automatically position themselves in the right location using tiny ion engines (also already been done).
The solar panels would produce electrical energy, which would be beamed down to earth via microwave. The panels would only be maybe 40-50% efficient, so the waste heat would radiate out to space, reducing the total thermal load on the planet.
Presto! Problem solved, and probably would be a profitable endeavor for some future megacorp.
You cannot extrapolate from the occurence of "new technology" in the past to help us, onto future new technology coming at time to help us. New technology is in general an unknown, and thus you should NEVER plan with them in mind. The new technology could as well NEVER happen and so much screw you up in an irreversible way. Which is why it is insane on planning on new tech coming (ne crude extraction tech, new energy generation tech (including fusion), new food production tech, new recyclage tech , new medicine tech etc...). A sane planning should always be based on current tech. You can always adapt your planning if a new tech comes up. You can't if you are waiting for some new tech to come (when ? In how far the problem would be solved ? What problem would be left ? etc...). waiting for new tech to solve your problem is akin to waiting that the problem solve itself. And that is totally utterly lost on you.

No, much more likely we'd be gone, and in a few tens of millions of years
Let's just hope that whoever will be putting our bones in a museum will get a little sophisticated and won't think that digital watches are a pretty neat idea.
Considering the evidence that climate has been cyclic with a cycle of approximately 100k years for the last million-odd years, leads me to think that there must also be negative feedback loops involved here. You seem to have missed that. Badly.
Yes, I realize this doesn't mean that there couldn't be a magic global temperature or CO2 concentration at which suddenly this behavior breaks down. But somehow, I don't think we know all that much about all the processes involved.
Wasn't that nuclear winter?

I suggest you read this and see why the Sun is not responsible for our current climate problem.
At the risk of sounding out of place. I listened to this on the drive to Bar Review Class today and the point was that the damage we have done is relatively irreversible, but we can stop the magnitude of the result by limiting green house gas emissions in the present. That is not particularly outlandish, but it is also slightly disheartening to see that we have passed a threshold of no immediate return. That is the reaction is moving in a reaction to restore equilibrium.
I think we need to not discount technological possibilities of the future, however, curbing carbon emissions is a laudable goal for the present.
I suggest you read this and see why the Sun is not responsible for our current climate problem. Mars receives a tiny percentage of the Sun light the Earth does so we should be seeing a corresponding percentage increase. Jupiter's climate is mostly driven from its internal heat not the Sun (and we really don't know much about that). What about all the other planets, Mercury? Venus?
Earth has not been 'far warmer'. See the hockey stick.
Cold in DC and in Europe for that matter is due to slowing of the Golfstream and masses on polar region air coming down, both of those phenomenons are activated by global warming.
It could be that the natural negative feedback loop for the global warming is the formation of an Ice age cowering Europe and most of the USA under miles of ice. That might balance things out. In a couple thousand years.
So ... 10 billion people, frozen Europe, Canada, USA, Russia, scorched deserts in most of Afrika ... where will we all go to live? Will everyone migrate peacefully? How many billion people will be killed in wars to control few strips of land that are still fertile? And how many billions will die of starvation because they did not have the military power to get those lands?
Not so fun.
I don't really see why that's a failure of logic. Her point seems to be that, look we've pushed it to the point it's going to happen, let's not make it even worse.
The event isn't going to be a simple binary yes it does happen/no it doesn't happen it's going to occur on a sliding scale, it could be major, it could be minor, it could be anything in between, how we react is going to define that.
The logic only fails if you're viewing the result in a simple two state it does/doesn't happen manner. It's your application of discrete logic to a comment about a non-discrete system with a non-discrete range of outcomes that's at fault.
If what she says is true and that it is irreversible, then yes we need to do something about it- it means we've fucked up majorly and we need to do something about it now to ensure the impact it has is as small as possible. Certainly going with the attitude of "Oh well" and continuing as is is likely only going to make it a whole lot worse, or even speed it up so that it happens not in 1000 years, but in 100 years. Even if we can keep it to 1000 years and it is serious then at least there's the hope we'll have a better solution by then, but a solution in 100 years could be a much tougher call.

Mars and Jupiter have been experiencing "global warming", too.
Oh yes, you're totally right! I bet you're the sort who argues over accuracy of Earth's temperature records, but you're willing to believe that we have enough data to show global warming on Mars and Jupiter FFS.
Anyway. From Realclimate:
There are shills on slashdot. Apparently, I'm one of them.
Well, I probably just biased you into thinking I'm a climate change denier with the title, but guess what... I buy into science.
However, there is such a ridiculous, self-reinforcing feedback loop of grandiose speech and groupthink within the climate research community that its no wonder quacks out there are encouraged towards disbelief. If you attend lectures by some of these researchers (personally, its been mostly atmospheric chemists for me), you'll see that nearly every one of them thinks they're some sort of Messiah trying to spread the holy message. This article (the original, not the fluff news summary) is no exception.
In order to secure a newspaper headline title (once again, in order to get THE MESSAGE out), Solomon completely ignores a range of facts and potential solutions.
First fact, she admits in the article that people have previously predicted the consequences to last centuries. Apparently, when you increase the timescale from 200 years to 1000 years, you pass her arbitrary distinction between 'reversible' and 'irreversible'. How about we agree to refer to this as possibly reversible on a really long time scale, huh? And instead of Solomon saying that she was the one to discover global warming was 'irreversible', instead say that it will take longer than expected to return to normal?
Second, Solomon DELIBERATELY turns a blind eye to research already in the literature that contradicts her model. This surpasses vanity and enters into the realm of negligence on the level of an ethical violation. I'm talking about the emerging field of carbon sequestration here. Anyone in the field of climate research WILL know about the branch of research focused on removing and confining CO2 from the atmosphere. While any implementation is still a long way from large scale deployment or commercial viability, if you're going to make predictions on a 1000 year time scale, you might want to take into account technology advances in this field! However, that would destroy Solomon's pretty newspaper headline and reduce it to the following:
Global warming might last five times as long as previously expected assuming we don't find a way to fix the problem first
.
Does that sound front-page newsworthy to you? Ok, I support the theory of man-made global warming. However, if we want to persuade the skeptics and nuts out there, climate researchers should start approaching the issue honestly and responsibly. Half truths will only undermine further discussion!
Don't buy car insurance, either.
After all, you've never had an accident! Who are those doomsayers who say you HAVE to?
In the 70s they were also predicting a coming ice age.
That has been refuted even here on Slashdot IIRC. Global Cooling article in Wikipedia says:
"Of those scientific papers considering climate trends over the 21st century, only 10% inclined towards future cooling, while most papers predicted future warming."
Which doesn't mean your statement is necessary false, but you should provide some data supporting it.
The headline is a little alarmist, but the article is more reasobable:
One of the things people don't understand about science sometimes is that it doesn't set policy because it requires objectivity. Goals, which are the basis of judgement and therefore decision making, are subjective.
I think the point is that the site (antithetically americanthinker) is politically/economically motivated bs.
... the fact that "ice caps" are the least of our worries. Diseases, spread by insects, could become widespread as insects migrate to previously colder climate zones. Malaria, dengue fever, West Nile etc. That will probably be the quickest "experience" we have with global warming.
As we currently do not have correct antidotes against these diseases, I call your bluff.
Slashdot: stuff for news, nerds that matter, matter for news, stuff that nerd
I think they were right (about the coming ice age).
During the "mini ice age" 300 years ago, the notable feature was the lack of sunspots. Guess what the latest photos of the Sun show - NO sunspots.
Temperatures have also been going down, not up recently.
Analogy time. If you're trying to optimize code for speed you want to work on the region of code where you're spending the most time in already. It's the same as with temperature on the earth. The biggest input is the Sun. If the Sun cools down, as it apparently does periodically (periodic ice ages are fairly well documented and proven), then things get colder.
If one was *really* concerned about Global Warming, one would want a thermostat applied to the Sun. No one has suggested that. I find it remarkable the Sun stays as consistent as it does.
Anyway, the Sun is a first order effect, and anything man-made is at best several orders beneath that. We have more to worry about if the Sun suddenly becomes unstable and goes nova than this so-called Global Warming.
I'll leave it to someone else to provide a car analogy.
There is a myth that they predicted all apocalyptic shit in the 20th century. I remember when Limits came out .... its predictions were aimed squarely at the early to mid 21st century.
That was not what they were teaching in schools 20 years ago. Oil was supposed to have run out about 1997 or 1998 and tin 1990ish.
Oopsy!
Oh wait! We *did* already run out of oil out of the ground and all of today's oil production comes from extraction from teenager's faces![1] How could I be so dumb?
[1] Who would have thunk that Mel Brooks could save the world?
I get the joke but I'm not sure how we ended up on limits of growth and horse shit, that is not what TFPaper is about.
What it says is that IFF we stopped pumping out GHG tomorrow it would take thousands of years for the ocean to regain it's pre-industrial PH level. The ocean (and the shelled critters in it) is the largest C02 sink, too much CO2 makes the ocean slightly more acidic and this is already having a negative affect on said shelled critters ability to make shells, loss of coral reefs is the most publicised of these effects. Personally I hardly think it's surprising that it would take a long time for makind's CO2 spike to be aborsbed into the system if we all dropped dead tomorrow but science is about measurement and evidence, the question of "how long would it take" is as valid as any other.
limits of growth and horse shit
I like the horse story but the Dodo bird meat industry didn't fare quite as well. Tecnology may one day overcome that "temporary" glitch but until it does the Dodo meat industry went past it's own limit to growth in the 1700's(?). While we are LIMITED by our lack of terra-forming technology I think the most obvious limit to growth comes from from human shit, not horse shit.
As far as I am concerned we have no choice but to turn to technology to fix technology. However it's nice to have a "bug report" that clearly lays out what the problem is. Science is that bug report, without these kind of studies we wouldn't even recoginse the problem, and in fact many people still don't (just look at this thread for examples).

These professional pessimists have always underestimated mankind's ability to change, adapt, and solve problems. They've always underestimated our capacity to make things happen.
These people have their value though.
Without their strong caveats who knows whether enough of us would feel compelled to actually solve those problems before they blindsided us like a stealth missile.
All optimists, progressives, and risk-takers express this kind of dismissiveness about such dire predictions, but without them, and those who act on them, our decisions would become reckless very quickly.
For instance, if nobody started raising severe alarms about energy use, we probably would have all died in a third world war caused by people fighting over oil for their 10 gallon per mile cars.
VLC FOR MAC IS DYING! IF YOU DEVELOP, PLEASE SAVE IT!!
Yeah, 32000 "scientists" from just about any field that allows one to get a PhD should easily trump many thousands of scientists from the fields closely related to climate science.

We can produce food for many times what is on this planet. The only difference is that diets will adjust to which food products can be readily produced. Do you understand how much land that is suitable for farming isn't even used?
Susan Solomon is a CO2 freak. Her contention has been that we produce too much CO2 but every time I have read her interviews she spouts the changes in how much we produce without going into how much is naturally occurring. In other words, it looks bad if you just see how much more we produce but mankind has nothing on the mother nature's numbers.
Hyperbole for the win by the way, we have lots of fish, the key is who is farming it and where. Certain vocal industries are decrying loss of fishing but what good does putting a restriction on where our people can fish if our neighbors don't.
The whole problem with the GW is caused by man is that it really is "GW is profitable to certain men". Cap and Trade is the outcome these people want because it will make them money. In the mean time poor chinese and africans will lose their lands to damns and energy projects that benefit the rich world and a few rich people.
Lovely.

Are any of us truly surprised.
How many of us just want to believe otherwise, as the idea of it is so difficult to accept. I imagine that one could almost put a name to the mental behavior that so many of us have as we consider this.
It really _has_ always been about adapting, rather than avoiding. The bomb has already gone off, the walk of the meek is at hand.
There is plenty of food.
Where we struggle, as human beings, is getting it to the people who need it. Politics, not capability, determine who gets fed and who doesn't.
We have PLENTY of resources to feed 7bil, 8bil, or even 10bil people. That has never been the problem. It's our own selves that is the problem.
It seems all our problems would be solved if we were fewer...

In actual fact we currently produce enough food for over 7 billion people. (Some is turned into ethanol, some grain is used to fatten up meat animals, some food goes to overweight people like me ... all because food prices are historically low.) The reason millions of people are starving today has nothing to do with global production shortages -- it's because of political failures.
If by "threw up their hands" you mean "publicly funded and built a massive underground public transit system" and "pushed the adoption of automobiles by adopting increasingly auto-centric laws", then yes, they "threw up their hands".
If you actually knew your history rather than assuming that things then were as things now, you'd know that the public transit system in New York was not built by the government, but by private enterprise looking to make a buck. The move to put it underground was funded by city bonds, but it the elevated train system was already there. Furthermore, "auto-centric" laws came as result of the mass adoption of automobiles by the public at large, not the other way around.
If a job's not worth doing, it's not worth doing right.
Well its funny because every manner of fossil fuel is in a state where we are getting "not as good" raw material out of the ground. I'm hardly a big environmentalist but I can't see how anyone can deny any peak fossil fuel or even nearly planetary resource.
The oil we are getting is not as good and harder to extract. In old oil fields you drilled a few hundred feet and you could just pipe it onto a rail car and you were good to go. Now you have to go thousands of feet, blow compressed air into the ground to smash up rocks, heat the oil so you can pump it, and then you have to refine the crap out of it to use it. Even good old coal is certainly not as good - Germany is practically onto burning lignite and that's pretty crappy coal and even in America the good hard stuff is getting used up and we're onto lower grades of coal.
Even for metals you have to wonder where all the good stuff is. In the 19th century, people were getting gold out of the ground and you could SEE chunks of it. Now, when they talk about gold mining, they don't even bother screening the miners because the gold content of the earth is so low that a miner would have to take out an F-150 sized truck of the stuff to get a few bucks.
Meanwhile, up in space, we have an asteroid that is quite literally made out of 20 trillion dollars worth of practically pure iron and precious metals, a planet made out of methane, and we're sitting here with our thumbs up our rears, barring ourselves from using nuclear power to make spaceships with, when unimaginable wealth is in the skies above us.
You don't need to be a scientist or a genius to see where the future is. All you need is to read an assay of a asteroid, and compare that to an assay of what's considered to be a good project today. Right now, if we took a tenth of the capital we spend on developing technologies to get every last scrap of goodness out of our used up planet, we could have enough materials of any kind to essentially end all of poverty on this planet.
There is no long term environmentalism without the conquest of space.

The only problem with your argument it the complete fantasy that your altruistic busybody is both going to show up and his/her replacement is going to continue in their do goodery. As flawed as free market and capitalism is, it feeds of the basic human instincts of greed and desire to harness them and use them to further the economy.

They had an entire crew killed on the launchpad on the very first go, and the crew of Apollo 13 were dumb-shit-lucky to make it back to earth. Six of the missions actually landed on the moon, out of SEVENTEEN missions (yes, a number were not designed to land on the moon, or even leave earth orbit.)
Even if you're exceptionally kind, NASA failed to reach the moon 1 in 7 tries.

"I am not a climate scientist, but I believe that if I don't understand no one else possibly could," would have been a sufficient answer.
There were two papers written about it, one was in Scientific American. Everything else was media hoopla. Carl Sagan was going on about nuclear winter, but mostly the "global cooling" stuff is being resurrected by people who are politically motivated.
When did I write that doing abortions is the same as taking care of children? You need to get back to your Logic101 classes.
Um, how about right HERE:
That includes not preventing pregnancy, not doing abortions and not taking care of their children properly.
See, this is where you were talking about the poor, ignorant masses that are all too fatalistic to either:
a)not have children
b)abort those unwanted children
or c)take care of those children they DO have.
Right there would be where you were setting up implied equality in the situation, by listing all the alternatives in a grammatical structure of balance.
I'll use an example you should relate to easier: Now that Obama is in office, we'll have less taxes, more money, and a better economy!*
See, that sentence created a progressive equality, just as yours did. With mine it was: Less taxes leads to more money which leads to a better economy! Yours was that if those poor folk had any sense they'd: prevent pregnancy, abort the ones that DO happen, and take care of the select few that they decided were "keepers."
