There are more photosynthetic organisms than just trees. While planting trees and turning them into wood/charcoal works, it's inefficient, and takes up a huge amount of land. Something like algae would be much more efficient. I've seen a number of proposals/studies done about natural carbon sequestration, and from what I've seen algae is the way to go.

In addition to carbon sequestration, you can use the algae to produce biofuels or food for animals. There's a bunch of articles about it. This article covers the concept pretty well.

Forgive me if I'm missing the obvious, but when I think about mechanical or science based ways of physically pulling carbon from the atmosphere vs the hundreds of millions of cars and ships and factories pumping it into the air, I can't help but laugh at the 'spitting in the rain' feeling I get. Creating a bunch of carbon trees just seems so puny compared to the problem - is it realistic at all?

The way I look at it is that every bit helps. And you can capture the carbon near the source to feed it to whatever your sequestration method thing is to make it more efficient (eg take the emissions directly from the coal plant's smoke stack instead of waiting). And how "puny" the effort is completely depends on the method(s) and the scale.

But yeah, carbon sequestration is not a solution by itself, it's merely another step we can take to un-gently caress ourselves. Society absolutely needs to switch to zero-carbon energy for any good progress to be made.

Since you seem to be unaware of what is taking place in the world from an economics standpoint, let me catch you up - Europe is currently embroiled in a debt crisis. Greece is so deep in debt that they are cutting government spending at a rate that is causing rampant unemployment and social unrest. The "recovery" is stalling in the developed world, and the debt crisis threatens to tear apart the eurozone and throw a few more of its member states into the same situation that Greece is in.

The United States is not even close to immune from the turmoil. Our debt-to-GDP ratio is dangerously high, and we've tacked on about 5 trillion dollars worth of debt since 2008. Many of the biggest banks in the U.S. are heavily exposed to European debt, and a Greek default may well kick off a double-dip recession. If the U.S. government manages to stave off recession with more spending and bank bailouts, we'd be setting ourselves up for a credit crunch, and we'd probably get to choose between the dollar being dropped as a global currency (a nightmare scenario) or austerity (see Greece). "The government can just nationalize the energy grid!:downswords:" is a totally unfeasible solution in the current economic climate.

Climate change and resource depletion are problems that are economic as well as environmental. Both problems are massive externalities that have been ignored for years, and the cost is now showing up in insurance payouts and government disaster relief programs, as well as rising energy prices. Any solution that doesn't deal in both sides of the issues - economic and environmental - is wrongheaded, and represents a fundamental misunderstanding of what is going on.
Austerity is certainly not the solution to the economic crisis. The crisis was caused by the recession, which was in turn caused the mortgage crisis and its cascading effect. There's still plenty of money out there. The problem is that the money is all in the hands of a few people--millionaires, billionaires, and massive corporations. Taxing those entities would immediately give us enough money to resolve the "debt crisis," and more importantly, enough money to employ a whole lot of people to completely revamp the energy infrastructure of the United States (and Europe, and anywhere, really, if the same methods were applied). The other part is to nationalize the major industries (energy, banks, etc) that have clearly shown they're unable to not cause global economic turmoil and horrid externalized costs that will affect billions.

Now, the problem with some of the recent nationalizations we've seen is this: The governments nationalize the debts and bad parts, then give away the good parts to a bunch of rich assholes. Ask yourself this: Is the energy industry profitable right now? Well duh, or it wouldn't be run by profit-seeking entities. For the fossil fuel-related energy industries, that's only because they've been able to externalize the costs. But it doesn't matter. The point is, the government nationalizing something like the energy industry doesn't mean it has to go further into debt. Indeed, it makes money, and that helps solve the so-called debt crisis!

The problem with so many looks at the solutions to climate change and the current economic recession is that those looks only are through the lens of capitalism, especially neoliberalism and this ridiculous idea that countries shouldn't be in debt and the rich should get richer so wealth can trickle down. Hell, even the so-called "socialists" in Greece bought into it, and were calling for austerity and cuts. Has that worked? No. Has it worked anywhere its been implemented? As far as I know, no.

But there is precedent for getting out of a horrid economic recession: Massive government spending. We got out of the Great Depression by the massive government spending that was World War 2--and you bet your rear end the government went deep into debt to do it. Now obviously, we don't want there to be a world war 3 just to get us out of this current crisis. But the government spending doesn't need to be directed at war: It could be directed to building massive renewable energy projects (wind, solar, nuclear--I don't care, though I think the latter is the most realistic), infrastructure, etc. That would solve the climate crisis and the economic crisis with one fell swoop.

The problem is not scientific, or technological. The problem is not that no one knows what to do. The problem is systemic, and for that, we need systemic change. The current powers (both governmental and economic) that are driving the world towards a ruinous path need to be removed, and a system that can deal with far reaching consequences implemented.

The headline seems like it will get spread around, with the bolded parts ignored. And the albedo changes and other feedback loops will probably counteract this quite a bit.

Deniers will cherry pick text as they always do. As long as there is either a ideological or financial incentive to deny reality, it doesn't matter how much evidence you present to them.

The results of this study don't seem very surprising to me. As the ocean and atmosphere mix, the ocean absorbs basically a set percent of air. If that air has higher concentrations of CO2, then, yeah, ocean uptake of CO2 is going to increase.

The big problem though is the second part you've bolded: at a certain point, the ocean gets saturated with CO2. Then, suddenly, this huge carbon sink disappears, and warming accelerates. Meanwhile, as CO2 gets absorbed into the ocean, ocean acidity rises accelerating the ecological crisis there. Nevermind the rest of it, that the ocean is absorbing more CO2 than previous studies thought should be cause for alarm all by itself. Fish stocks, coral reefs, etc are already in distress--this only will speed up extinctions in the ocean.

What do you mean? That you would need nuclear weapons to mess up a nuclear plant?

First, if someone is bombing a nuclear plant, that implies there's either war or terrorism going on at a significant scale that's probably way worse then slight radioactivity.

Any bomb big enough to threaten a nuclear plant (turns out the concrete containment dome designed to protect the outside from the reactor does a great job protecting the reactor from the outside too) would kill more people if it hit a city. The worst case scenario of radioactive release from, say, a light water reactor would be peanuts compared to that. Newer generations of reactors with passive safety features (which we would be using if there was a large scale switch to nuclear) would be even less vulnerable to bombs/etc.

The planet and life in general will be fine. Life has survived snowball earth, toxic atmospheres (oxygen!), massive meteor impacts like the K-T, and 6C+ warming spikes (PETM). Life will be fine. The planet will be fine.

Fighting climate change is, to me at least, about preserving humanity and minimizing human suffering first, and preserving the current ecosystems and species second.

In no way does nuclear destruction help any of those goals and you need to snap the gently caress out of whatever crazy-rear end mental state you're in that makes you think a nuclear holocaust would be on any level better for anything--humans, life, whatever.

I understand the pessimistic outlook on all of this. I get depressed about it all the time. But you then need to channel that sorrow into rage, and channel that rage into action. Humanity has not failed--not yet. Do what you can to build a better future. Join an activist group, protest, talk with people, run for office, lobby, work on changing the system that is causing this environmental crisis--anything.

In my opinion climate change is unstoppable. Historically speaking the earth has always been a hot and tropical planet (see the dinosaurs). It just so happens that we're emerging from the tail end of a catastrophic ice age that wiped out 90% of life on earth and its going to get a lot hotter before the planet returns to its natural tropical state.

Any reason why I'm wrong about that?

Current temperature is not dependent on historic temperature.

You're also conflating man-made climate change with natural climate change. On time scales of hundreds of thousands and millions of years, Earth's climate changes. Due to solar cycles, continental drift, feedbacks, volcanism, etc. That stuff is unstoppable. The climate change everyone in this thread is talking about is man-made climate change, which is directly caused by the greenhouse gases humans are putting in the atmosphere, and that climate change is absolutely stoppable.

Well it's not so much that I accept it, just that it's not as obviously inane as I expected. I mean he's not an expert, but he does link to articles by experts that at least seem authoritative. So that sort of threw me off. I mean I guess my question is something like a) is it really true that the global mean temperature has dropped since 2003? and b) is that at all meaningful or is it just some fluctuation within a larger trend?

Here is a site that debunks common climate myths.
  • The planet has continued to warm. 1998 was a very warm year, but that doesn't mean the planet is cooling. It's a single data point that gets taken out of context in order to show later years are cooler, but NASA article with a nice graph of temperature. 2010 and 2005 were the warmest years on record (source). "Climate" is an average of many years of weather. We can safely say the climate is warming. It doesn't do so liberally, it dips and peaks. So for example, the decade of 2000-2009 was the warmest in recent history, beating the 90s.

  • Climate change causes extreme weather, and that includes blizzards (basically, because of increased energy imbalances and increased precipitation). No reputable scientific body has claimed winters will disappear (they're caused by the globe's tilt, which isn't going anywhere). While glaciers and snowpack will gradually disappear in the coming decades, and the arctic will disappear in the summers in a few decades, no one has claimed it would happen immediately.

  • Climate change is caused by humans, in case he tries to pull that one. We know that due to analysis of radioisotopes of carbon in the atmosphere (natural carbon and burned carbon have different isotopes, so the proportion over time tells us the CO2 spike has human origins. Also, you can just look at the industrial records of setting huge amounts of fossil fuels on fire).

  • The Earth has indeed warmed in the past. And in the Paleocene Eocene Thermal Maximum it caused a mass extinction in the oceans. It was the fastest spike of temperature we've found in the geological record, and it happened over ~20,000 years. Our temperature spike is happening in ~200 years. The speed and magnitude are the problems: we, and many other species, are going to have trouble adapting to climate change that fast.

  • There are some scientists who disagree with climate change. Don Easterbrook is one of them, and at the university he goes to, people don't like to talk about him. 97% of scientists do believe in climate change. That doesn't matter either, but what does matter is the evidence and observations support those scientists. As the IPCC report details. Now, the alternating periods of warming and cooling are the ice age cycles, and they're caused by Milankovitch cycles. Without human interference, we would be eventually heading into another ice age. But the amount of CO2 we've put in the atmosphere has changed that. Pretty much every simulation predicts that.

Most of the statements on that site are outright lies. Those that aren't either are an appeal to the authority of a single scientist (who's conclusion is not supported by evidence) or taking information out of context, or cherry picking data.

There are a great deal of people who are either on the payroll of the fossil fuel companies or are ignorant of the subject and make wild unsubstantiated claims. So for example, here's an article showing that. There's plenty more where that came from. There's a lot of financial incentive for fossil fuel companies to deny climate change, because if climate change is true it means the end to their billions of dollars of profit and a switch to different energy produces. It also threatens the world view of conservatives (that's a great article by the way).

Basically, the easiest way to do it is look at the first site I linked and use it to counter any of his claims. Anyone denying climate change will pretty much never admit defeat, they'll just move from claim to claim, constantly shifting goal posts hoping they can finally claim something you can't immediately refute. Suffice to say, they are full of poo poo and all evidence points to that. We can already see the effects of climate change with the recent droughts and extreme weather all over the world, and the gradual disappearance of the arctic ice.

Really, I can go on, but hopefully that's enough resources for you to (hopefully!) correct him.

When convenient, call out socialists when they try to conflate their twisted ideals with environmentalism.

None of this is particularly controversial or even non-obvious.
What do you do when neither of the major parties you can vote for take a pro-environmentalist stance, and the few, much smaller parties that do actually have a genuine environmentalist platform have no hope of winning (when they even can run a candidate) because the two major parties benefit from absurd amounts of money from corporate donations and systemic rules put into place to protect their power?

Not sure what you mean by the second and third sentence, could you elaborate?

The solutions to climate change are controversial and not obvious. That's because the problem is not scientific, or even an engineering problem (the answer to those problems are fairly obvious), but one of politics and economics. If there wasn't controversy over what to do about those, you'd be missing a lot of the debate from this thread.

Um, doesn't the middle ground position, as far as scientific consensus goes, still have us totally screwed?

Pretty much.

All evidence I've read though says the IPCC worst case scenario low balled it, because we're currently beating it and right on the path for 6 degrees C or more warming in the next century.

But yeah, even if it is some sort of middle-ground 3-4 degrees C rise, that's still enough to drown several island nations and cause global catastrophic damage that will likely kill millions.

Edit: The tagline for the wired article ("Why the world won't end in 2012... or any time soon") is technically correct because the worst damage will take decades to hit. It's basically a strawman though: No one who knows anything about the issue claimed the world was going to end this year or next.

5. Nothing other than a prolonged period of planned austerity will really work.

How would austerity help? To end CO2 emissions, you either need to
a) Pretty much cease producing most electricity, using cars, trains, planes, ships, which would plunge the world into poverty, starvation, and total collapse, or
b) Massive infrastructure projects that switch from carbon emissions, eg. building massive amounts of nuclear, solar, wind, electric train systems, making buildings/cities more efficient.

The latter uses carbon initially, but actually solves the problem. The former either delays it or causes enough damage we might as well have let climate change take its course. Even if you could convince everyone to live in horrid conditions and poverty for years (hint: you can't), I don't think you're taking into account how brutal the kind of global austerity needed to significantly lower carbon emissions would be.

Take a look at Greece, for example. Austerity there has torn the country party. There are people starving, committing suicide, rioting, and the horrid conditions have pushed people so hard they're willing to reconsider facism in the hopes it will help. Measures that would actually reduce CO2 emissions would be worse, and the effects would be worse too. I mean, think for a moment how much our society depends on cars, trucks, and electricity. Reducing those to the point where CO2 goes down with no replacement is a disaster. Any solution to climate change should prevent mass death and suffering, or it's no better than the problem it tries to solve.

So, this is a really stupid question, but I'm having a tough time parsing all the readings and articles in the thread, so I'll just ask: precisely how hosed are we? Are we "just" red-alert-holy-poo poo-if-we-keep-doing-this-we're-doomed level, or has the apocalypse point pretty much already come and gone? Because I'll just start leaving all my lights on right now if that's the case.

It's hard to predict, because climate is really complicated. Here's what we can say:
  • Ice is melting and extreme weather (such as the recent drought in the US) is on the rise faster than most scientists predicted. On that note, we are on the track of the worst-case IPCC scenario, and heading towards above 2 degrees C warming in the next 50 years (which is very bad).
  • If carbon emissions are not drastically lowered, the worst effects of global climate change will occur, probably killing tens of millions minimum. It's hard to predict exactly how much time we have, but the window where we can prevent the worst damage closes around 10 to 20 years from now.
  • No matter how bad it is or is going to get, we need to try and get to zero carbon emissions, because it can always get worse if we don't.

It's not too late yet. But the sooner we act, the more lives we save. Of course, leaving your lights on or turning them off makes no difference. What we need to stop climate change is massive, systemic change on the global level. I think the only way to do that is to have mass movements on the streets that lead to those changes.

It may be a typo or a missing word or something but I am having trouble extracting meaning from this, but allow me to see if I have it right:

1: Oil companies use tricky/bribed science to gin up a figure on atmospheric carbon that is something like 400-500% the value widely accepted by science as a 2C tipping point (say the actual point is 350ppm, the value the oil guys are pushing is 1400-1750ppm before we get on track for a 2C increase in avg temperature)

2: the reason they are doing this is that if they were to accept the truth and adjust production to fit into that 350ppm ceiling, they would need to take a 20 trillion dollar write off.

Is this close?

Part of the value of oil companies is based on oil they can profitably extract, but haven't yet. The value of that oil is ~$20 trillion. If that oil was burned, it would get us to over 1400 ppm of CO2, which is super very mega-bad. To instead keep us below 2C of climate change, the oil companies would have to not use that oil, meaning they basically lose $20 trillion.

I hope I got that right and that makes sense.

Something will happen, certainly, but my point is that the dots have not been connected to global collapse of modern civilization. Maybe somebody has and I'd be interested to see that. But the dominant story in the last few pages of the thread of total collapse of civilization and a catastrophic return to primitivism (which is itself an anachronistic concept) hardly seems inevitable to me.

Predicting the effects of climate change a few decades out is hard enough; predicting the most likely path of it's effects on civilization is magnitudes more difficult.

That said, one can figure out pretty easily general patterns that will emerge from climate change:

1. Primary effects: Extreme weather (heat waves, drought, storms, flooding, etc.), rising oceans, and loss of ice (contributing to droughts).
2. Secondary effects: More pests (not killed by winters), disease carrying bugs (as climate zones shift), desertification, and massive crop die-offs (see: all of the above), more deaths due to storms, mass starvation, and mass displacement (due to flooding, starvation, storms, climate zones shifting).
3. Tertiary effects: Studies have shown people without the basic necessities of life (food, water, shelter) are more likely to fight, so war. Realize the scope of the damages, and you realize conflicts would be everywhere and widespread. Also,
4. Compounding Problems: There are a huge number of problems that aren't caused by climate change, but will compound it. Growing world wealth disparity and loss of basic necessities will (and has) provoked unrest all over the world (Europe and the Middle-East are on the news quite a bit). Aquifers are being depleted far faster than replenished. Society is completely dependent on fossil fuels, which we need to switch completely off of (and soon) or they'll compound any other problems. Add to all of that the current economic system (capitalism) that values profit over lives and society and is able to basically buy political power, and you have a recipe for a cataclysmic disaster.

Yes, it's vague, but as I said, no one can predict exactly how things will go down. The point is, it's going to be bad stuff, all over the world, simultaneously.

Edit: I don't think things will regress all the way to the stone age, but if things remain on course, it will probably regress society, standards of living, and technology a whole bunch, and kill a few billion people.

Well that's pretty obviously going up. But if you do this:

...wow! It's not so threatening now, is it? Yes, if you cherry-pick data, you can do amazing things!

The article is pretty clear biased. For example, look how this section is written:

That lovely Denialist Rag posted:

Some climate scientists, such as Professor Phil Jones, director of the Climatic Research Unit at the University of East Anglia, last week dismissed the significance of the plateau, saying that 15 or 16 years is too short a period from which to draw conclusions.

Others disagreed. Professor Judith Curry, who is the head of the climate science department at America’s prestigious Georgia Tech university, told The Mail on Sunday that it was clear that the computer models used to predict future warming were ‘deeply flawed’.

Even Prof Jones admitted that he and his colleagues did not understand the impact of ‘natural variability’ – factors such as long-term ocean temperature cycles and changes in the output of the sun. However, he said he was still convinced that the current decade would end up significantly warmer than the previous two.
Note that "some scientists" in the first paragraph are 97% of all climate experts, and "others [who] disagreed" are generally either not scientists, not climate experts, or quite literally on the payroll of fossil fuel companies (or the organizations they fund). Note, though, that Judith Curry is head of a "prestigious" university. No such adjective is given to Phil Jones' organization. The argument is presented as if both sides have equal weight in numbers or evidence, when that's not even slightly true.

Then you get poo poo like "Even Prof Jones admitted that he and his colleagues did not understand the impact of 'natural variability'..." which is something climate scientists have been saying for ages: Climate is super loving complicated, and we still don't understand large parts of it. We do understand thermodynamics, though, and have enough data and models to accurately predict the globe is without a doubt warming.

Here's some other problems with that article:
  • Mentioning "climategate" as if all scientists involved weren't absolved of all wrongdoing
  • Repeatedly calling the natural variability of the sun not understood as if it wasn't pretty drat well understood
  • Continuing to use vague numbers for "skeptical scientists" to hide how small the number of said scientists actually is
  • Disingenuously conflating weather and climate
  • Hiding, quote, "Yes: global warming is real" at the end of the article, which is awesome because they're literally contradicting their own headline

Individual action (such as turning off the lights, eating less meat, etc.) is piss in the ocean when fighting climate change. Community action isn't much better. Action that fights climate change needs to be societal and global, or it's still going to result in all the bad things, and if the current political and economic norms are allowed to perpetuate, it's just going to keep getting worse.

The best solution is to create a mass movement. The Labor movement, Civil Rights movement, Women's Suffrage, and other major movements throughout history advanced rights and made progress. What we need now is an environmentalist movement equivalent to restructure society. We need a democratically planned economy, not an economy where profit is king, because once society is run by everyone, it can be run in their benefit.

Also, as a socialist who would like to see the environmentalists and socialists link up in solidarity, I can say with good confidence that most environmentalists are not socialists, closet Marxists, or anything of that nature.

I think it goes beyond even how well-informed the electorate is. When it comes down to imposing austerity measures on yourself to benefit a nebulous other/future, humanity simply isn't emotionally advanced enough to do it. Even if you could educate an entire electorate to understand that they were suffering to preserve the future of their culture, you would have to convince them that not only was the suffering worth it, but suffering even more the following election cycle and then even more the following election cycle (as you impose stricter and stricter emissions limits) and so on would also be worth it. Politicians would be running on the platform of making things even shittier while their opponents promise to ease the suffering. Summed up well by this, which has been posted here before.

Only an autocrat is capable of imposing the long-term austerity needed to address the issue, in my opinion.
Austerity isn't the solution. There's trillions of dollars of wealth being hoarded by the capitalist elite and corporations, which if taxed would be more than enough to start rebuilding the infrastructure of the US (and if the policy was expanded to other countries, the world). The massive jobs program that would result would be akin to WW2 spending getting the US out of the Great Depression (without the death and destruction), and allow for a drastic reduction in unemployment while providing well paying jobs--which would effectively end the ongoing economic crisis.

Austerity is a tool of the financial elite to protect their profits. Even the IMF admits it doesn't actually work.

Now, I understand that many progressives think of regulations as laws and rules that are designed to protect consumers from corporate abuse and misconduct. Therefore, as with the economic crash of 2008, they attribute the unprecedented banking and corporate fraud and abuse to mean that we have less regulations than we did before. The truth is that business interests and corporations actually lobby for more regulations in order to hurt their competitors or grant themselves a monopoly. Therefore a great number of regulations on the books actually protect corporate interests rather than protecting consumers.
You're trying to measure regulations as a quantity, where "more" = "bad" and "less" = "good." That isn't how it works. "Regulations" can either be good or bad. The numerous regulations that were repealed that allowed the financial industry to crash the global economy were good regulations. Regulations that are targeted at destroying small businesses are bad regulations.

The quantity of regulations is irrelevant as long as they are crafted to be effective and serve the correct purpose; in the case this thread is talking about, that means strong environmental regulations that prevent fossil fuels from causing climate change and therefore starvation, sea level rise, drought, desertification, extreme weather, and a load of other horrific effects.

jrodefeld posted:

However, the market provides regulations that are usually stricter and more comprehensive than government regulations.
This is an incredible claim. You must have some sort of peer reviewed economic study that backs it up, so please cite it. Since this is the climate change thread, I assume your source is, perhaps, a case study of environmental regulations or directly analogous.

I would argue that the problems of stopping climate change are entirely economic and political. Finding solutions thus means addressing economic and political challenges, and therefore is in the scope of this thread.

The problem is that jrodefeld isn't actually focusing on concretely applying libertarian philosophy to climate change, but instead waxing evangelical as he spoutes vague, unsupported platitudes that derail the thread.

I couldn't respond to this earlier, but how so? Maybe not consciously; environmentalists I've known are often of the STEM mindset and don't have the background or experience in social sciences, politics, history, etc. And with a STEM education you don't get much policy context to what you learn, unless you take policy classes. But, to me, nearly every environmentalist I knew in college was prone to seeing how socialism fit with their ideas about the future. And more definitively, I think capitalism, consumerism excess, and the founding principle of constant growth were widely identified as the base problem with our environmental stewardship. So I definitely think that these kind of people would be, if not already, open to more central planning. I suppose they would not be very conscious of class struggle or social issues, which is something I have noticed. That comes with the education though, and as long as the costs of our new environmentalist economic paradigm are bore by the transgressing parties, or just plain ol rich people, socialism and environmentalism could be in harmony. Is this what you mean by environmentalists not being socialist?

I was just talking from my anecdotal experience with environmentalists. Mostly, they vote Democrat and yammer about solar and wind while shaking their head about how bad Republicans are, and haven't received socialist ideas too well when I've presented them. That's my experience.

I think that good exposure to socialist ideas framed in the right way should indeed convince them, since capitalism is the root of consumer excess and the political and economic policies that have gotten us into this mess. I think socialists and environmentalists should be in harmony since the two ideas mesh extremely well with no contradictions.

The government can't even spend the money it has efficiently. Why should I expect that if they confiscate most of the private wealth in the nation from people in a certain tax bracket that it will go to anything useful?

The trick is to get a government that does good things with money (such as rebuilding the US infrastructure to be carbon neutral, universal healthcare) and not bad things (awful wars, bank handouts, oil subsidies, etc.). How you accomplish that is up for debate. I'd rather do it through reform, but revolution seems more likely.

Government, like regulation, is a tool. It isn't inherently bad or good. However, if you're implying that somehow rich people and corporations hoarding trillions of dollars and raking in the majority of wealth each year are suddenly going to create a carbon neutral economy, I would be fascinated to hear how you think that's going to happen.

Also, seconding that the "government is inefficient" thing is a myth. For example, medicare vs. private insurance. Also, I have never seen evidence that private companies or "free markets" are able to successfully regulate their own damages to the environment, so if you have some evidence of that feel free to cite it.

*needless insults*

I think global warming is unfixable. The only way is to significantly reduce growth worldwide. Imagine dozens of self-inflicted Arab Springs. In the middle of pre-existing economic troubles. Not going to happen. Of course, once arable farmland is greatly reduced that'll happen anyways. In any case, it's too late to avoid that.

I might be a pessimist, but at least I'm not blind.
You've done nothing to refute Dusz's point. Why is stopping or mitigating climate change impossible? It's not. It's difficult, but there are positive steps that you and everyone can take towards stopping it/mitigating it, and the more people taking those steps, the more powerful the effort to stop climate change becomes.

Time and time again in history, drastic, practically unforeseeable changes have taken place, upsetting the status quo in ways that people probably claimed were impossible just years or even days before they happened. The revolution in Tunisia is a modern example. That one revolution is far from insignificant, and we can see how its effects reverberated throughout the world, into Egypt, Libya, Syria, and even inspired events in the US such as the 200,000 people protesting cuts in Wisconsin and later the Occupy movement.

Russia is a good historic example. Who would have imagined, as World War I began, that backwards Russia would, in a matter of years, go through multiple revolutions and end up one of two global hegemons pioneering things like launching spacecraft? Who at that time period could have predicted the leaps in technological advancement we've made today? Plenty of other historic events like revolutions in France in 1968 or in Germany or Spain after World War I could have taken history in a drastically different direction had they gone a little differently. Many people think of the status quo as a nearly unstoppable force, but it's anything but that. History is the tale of how unstable and capricious civilization really is.

One thing that is important is to learn how massive changes take place. Take the Civil Rights movement in the US, for example. Imagine if it had been just one guy trying to change the racism and systemic oppression of blacks across the country. Would that have worked? Hell no. So what did happen? Like-minded individuals began a long campaign of civil disobedience (some, outright violence), and attacking systemic injustice on every front they could, from shops to courts and legislatures. History books like to merely point to the prominent leaders of the movements, such as MLK, but they were nothing without the millions following them.

We can learn from that. Of course one dude changing his lightbulbs or a single or even a large group of scientists warning of doom aren't going to stop climate change. We need to do much more than that. A modern example would be 10,000 people encircling the White House protesting the Keystone XL Pipeline. Their efforts caused the pipeline to be delayed--Obama didn't want to risk pissing off the environmentalists until after the next Presidential election. Of course, too many people went home after that. A mass environmentalist movement needs to be sustained--looking at any mass movement in history can tell us that.

The environmentalist movement can also find allies. The ongoing economic crisis, high unemployment, drastic cuts to social services, and lowering of wages and the standard of living all over the country (and world, but I'm focusing on the US) is causing a great deal of unrest (again, Occupy was an outbreak of that anger. The problem hasn't gone away, and the frustration hasn't either), and fortunately, the solution to climate change is the same solution to the economic crisis. The massive restructuring of society (mass transit, new electric infrastructure, switch to zero-emissions power, revamping water infrastructure, renovate buildings to be storm resistant and energy efficient, etc.) all requires millions of people being put to work to accomplish in the time-frame we need. That sort of program would reinvigorate the economy and be a huge step towards climate change mitigation and prevention. And--one country setting such a powerful example would inspire other countries--or their people.

But something like that requires a lot of sustained, organized effort, and someone has to take the first steps. Talk to people. Join organizations, or create them if need be. Work on local environmental campaigns, or change the dialogue. If no one is talking about switching from coal power in your area, start that conversation. One there's a movement, it needs to be sustained and grown. I'm talking in generalizations here, but I can get into some of the specifics people are doing in my area. The point is, there's plenty of viable ideas on how to stop or mitigate climate change. They're difficult, but that doesn't mean they're impossible, and the only way to start changing things is to start changing things.

The point is that this extremely simple, extremely cheap, individual-scale step is one that very few people have bothered to take in spite of the extremely low barrier to entry.

Yourself and Dusz expect people to make extremely big changes on an extremely large scale when they won't even do something as simple as throwing CFLs into their grocery cart when they're out at a department store.

Thanks for completely missing the point and ignoring the rest of my post.

To elaborate on the single point you did respond to, yes, people should take basic steps like replacing bulbs, insulating their house, doing an energy audit and unplugging high-energy devices, using mass transit or bikes instead of cars, etc. Yes. Of course. I've already done stuff like that. However:


Even reducing all household electrical consumption to 0 would still only be 4.86% of US energy use. Individuals only modifying their lifestyle slightly is not enough. Stopping or mitigating climate change is going to require collective effort on a massive scale.

You were saying the future for averting climate change is hopeful because of the technological advances we had from 1915 till now, which is wishful thinking. "Technology will solve it" is probably the worst rebuttal that pops up in these threads all the time. We are not in any reasonable time span, especially with the current political climate and population response to the problem, going to replace our entire energy infrastructure and world economy. Nations live and die on the oil they sell and buy and the food we started growing in the green revolution is dependent on petrochemicals.

You also said change can take place because of movements in Tunisia and Russia and various places in the past 100 years but you are underestimating this problem, everyone in America could become carbon neutral tomorrow and you still have pretty much the other 96% of the worlds population to consider, expecting them to not continue developing as nations the same way we did with fossil fuels.

There is being defeatist and there is being a realist, which is better than being an idealist. Realistic discussion of the actual situation we face serves us better than hoping that we will come up with a new space program level of innovation for combating climate change or that any movement at any time in the entire world is comparable to getting 7,000,000,000 people to agree on anything, much less that they should endure further hardship in their lives for a long term benefit.

You have to solve all of those problems while we are already past the point of being able to stop climate change, and already decades past when we should have started this worldwide movement of amazing technological advancements and forward thinking for the betterment of mankind.

TL:DR we are so screwed
You completely missed the point I was trying to make. Let me see if I can rephrase it for you any anyone else who might be confused:
  • History has shown us that the world can drastically change in a relatively short time. Examples: Technology, Russia
  • Changes in society can spread rapidly once a single tipping point is reached. Examples: Arab Spring, Occupy
  • History has also shown us the way to create drastic changes in society is one step at a time, building towards a mass movement. Examples: US Civil Rights Movement, US Labor Movement

I'm not saying technological innovation will save us. We have all the technology we need to stop climate change, and though incremental improvements and small adjustments will help any mitigation effort, they're not even necessary.

Any mass movement needs to begin somewhere. Since the root cause of climate change can be found in capitalism, the best way forward is to have environmental movements and labor movements unite, fighting for small changes while building towards the much larger changes that will be needed to stop/mitigate climate change. I point to history as an example we can learn from.

Successful popular movements can inspire actions around the world. If the US became carbon neutral due to drastic policy changes forced by a popular movement, that wouldn't exist in a vacuum. Even ignoring the US's role as a dominate military and economy power with incredibly influence in global politics, that alone would certainly inspire action around the globe. One victory can set off a chain of positive events. Again, history is an example we can learn from.

The alternative to action is inaction and the deaths of hundreds of millions of people if not billions of people. Given the consequences of inaction, inaction is a morally reprehensible position to take. The immense magnitude of the challenge facing us should not dissuade us from acting.

Does that clear things up?

It seems pretty clear that people won't really engage in any solutions until it is economically advantageous. The works of non-profits in this area don't seem to be accomplishing anything.

Well, how will "stop climate change" ever become economically advantageous enough so that corporations embrace it? Corporations only are after short-term goals of profit and cannot take into account long-term costs. Fossil fuel companies collectively have a multi-trillion dollar monetary incentive to keep the status quo. Even companies that would, in the long term, benefit from stopping climate change (for example, food service and agriculture) seem very unlikely to contribute towards stopping climate change because contributing significant funds to that would give their competition a leg up and they'd be crushed.

Will it happen through the political realm? Politicians and high level government workers are not only participating in the revolving door of bribery and regulatory capture, but politicians in both major parties are completely dependent on corporate contributions for elections, and are heavily beholden to those corporations. Lobbyists for the entrenched elite disproportionately have influence over legislation and politics.

The current work being done to stop climate change, including that done by non-profits, is magnitudes less than what it needs to be, I'll agree there. A lot of organizations tend to only combat the symptoms of the problem, and have to do it with a (compared to corporations and entrenched interests) tiny amount of money.

However, I don't see current market incentives or politics changing one bit without either a sustained catastrophe (which would mean change is way too late) or immense pressure from the masses (which history has shown is possible and effective). Again, I think the best way forward is building a powerful labor/environmental coalition with socialist ideas of solidarity, militant resistance, transitional demands, and eventually, supplanting capitalism, the root of all these problems in the first place.

Even with something as 'simple' as a massive boycott or strike, I don't think the public is in a receptive posture. If OWS was a litmus test for the viability of popular movements at the moment, we failed the test pretty spectacularly.

The Occupy movement should be reassurance to any would-be organizers that the anger and frustration born out of the financial crisis is there, waiting to be directed.

Class consciousness and political activism in this country is currently low, but I think people are starting to open their eyes to the reality around them. It takes time, constant effort, organization, and a strong plan of action. As I've said before, I think the best plan of action is to join a socialist organization and try and unite labor and environmental activists with transitional demands that eventually lead to systemic change. Since reforms will almost certainly never be allowed by the elites to lead to that systemic change, revolution is probably necessary.

While I agree with your core sentiment, I disagree with your argument on foundational grounds. I don't believe this is a class issue, so much as it is an issue about resource availability. The middle class in this country will be lock-step against any such revolution because it will mean sacrifices on their part, even if they are superficial and skin-deep cultural changes.
Resource availability issues are class issues. The capitalist class that profits from the status quo has the resources (money, and everything that buys) to maintain their grip on power. If we're to stop or mitigate climate change, we need those resources.

The middle class currently being against revolution is part of the "not class conscious" thing too. They're getting hosed over just like everyone else, and climate change will devastate their lives as well. The middle class has blindly accepted the cultural values largely imposed on them by the rich who benefit from them. In my experience, people (especially white people) in the US rarely consider what they have "culture" and tend not to examine the beliefs they hold as sacred, or even that they are beliefs, and just as arbitrary as any others. That can change.

Even if I'm wrong there, the middle class is quickly shrinking, and given the current course of events, will continue to do so. I think the people in power--whether blinded by greed or whatever insane alternate reality they've constructed--have forgotten that even a modicum of security and comfort can keep people happy and quiet. Instead, they've demanded austerity, more wealth, and the deconstruction of social programs--and not just in the US, but all over the world. It's already led to constant struggles in places all over Europe. It will lead to a backlash here too.

As to the second point, the temperature anomaly has remained relatively constant for about 11 years now man. Look at any graph if you don't believe. I posted one from the IPCC a few posts ago. You can find the NOAA data here: ftp://ftp.ncdc.noaa.gov/pub/data/anomalies/annual.land_ocean.90S.90N.df_1901-2000mean.dat
Why didn't you just link the page with the nice graph? Here:

Huh, weird, 2011 was up .11C from 2000, but up .69C from 1880, and overall there's a very stead trend upward and no evidence that climate change has or will level off, what with most of the warming being in the oceans and major feedback cycles like the melting permafrost yet to meaningfully trigger.

Arkane posted:

On a 30 year scale, we're rising at a decadal rate of ~.13C, and warming is likely to continue at a rate none of us yet know.
The current rate of temperature increase is not the predicted rate of temperature increase. For example, a new model suggests (and here's another article about it) a 1.4 to 3 degrees C rise by 2050 even with a mid-range emissions scenario. The low end estimate of 1.4C is still more than two times higher than what we would expect if current trends continued. It's likely that by 2050 we'll have overshot the 2C mark that so many people and countries have agreed is the absolute limit to how much warming we can tolerate before things get exceedingly dire. Time after time, we see that climate change is likely going to be worse than initial predictions. Given that the new IPCC model still won't include the melting permafrost, that is a trend I think will likely continue.

Arkane posted:

The reason I brought up the constancy in the recent anomaly data is to highlight the fact that whatever extremes he perceives are likely due to local changes that do not represent global trends (such as warm winters or cold winters).
Except analysis (.pdf with citations here) suggests that many of the recent extreme weather events are due to man made climate change, the probability of extreme weather occurring has increased, and this upward trend will likely continue. So actually, we're already seeing the effects of climate change, and they're coming worse and faster than most scientists predicted. Have this article, too.

Some of the misinformation being spread by deniers includes "global cooling." Several decades ago, some scientists were worried there would be global cooling, and we could cycle back into an ice age. Note that most scientists still predicted a warming trend, and most of the "ice age" crap was spread by the media.

Now the evidence for warming is overwhelming, but deniers like to bring up old topics like that one to confuse people.

Either way, there's a very good chance the Midwest will face desertification and dust bowls due to droughts, and much sooner than we'd like.
