There is nothing we can do, as long China and India get a pass, 3.2 billion people in 2 country doing nothing. Even if the US disappeared off the face of the map, its still to late. I say let it happen, it will propel us into a new era off innovation and environmental awareness. No one is going to take it seriously until its to late anyway .

They're building solar power plants everywhere, shutting down factories and coal power plants around large cities.

"Other main targets include: – reduction of emissions from coal burning industries and vehicles2 – boost cleaner and more efficient use of coal – promote the use of electricity and natural gas in place of coal – support for wind, solar and bio power sectors; increase in proportion of clean energy – encourage the use of waste straw as a resource – reduction in-field burning – implementation of control measures to deal with air pollution

...

By 2020, he said, the intensity of water use per unit of GDP will fall by 23%, energy intensity by a further 15%, and carbon intensity by 18%."

What about U.S.? It's people saying "as long China and India get a pass... Even if the US disappeared off the face of the map, its still to late... so let it happen."

You're the problem. Even if the rest of the world disappeared of the map, U.S.'s carbon emissions and pollution still exceed world's capacity to absorb it. Do you know how much of the world's environment is scorched to produce raw resources to produce goods for consumption in the U.S.? You're not taking it seriously.

Not to mention that we're incredibly hypocritical about the fact that we happily burned coal and oil and continue to, but expect developing economies to just... stop. It's worse when you consider Europe getting uppity about migrancy, which is being causes in large part by drought related to climate change.

It's going to be the story of this century: the people least responsible for climate change are going to disproportionately suffer for it. Meanwhile those most responsible will demonize them for their efforts to survive it.

I hear this logic but dont buy it. Yes many western countries were polluting heavily during the industrial age, but that was using the best technology that existed at the time. The world now knows better about these harmful environmental practices, and has access to better tech to avoid this. If you apply this thinking that 'its what the other countries did previously' that's fine but then you do you expect developing continues not to utilise computers and other new technology for 50 years while they catch up? You cant have it both ways or your just cherry picking what suits your bias.

I feel the better arguement is that per capital these countries are lower polluters and we need to all strive to reduce pollution to an acceptable per-capita level. And as a global population need to look at how we lift everyone lifestyle while reducing environmental harm. This 'you had your turn polluting the world and now it's mine' lacks logic and will not solve the problem.

Except the better tech tends to be more expensive and less labor intensive. A country with a huge cheap labor force would handicap itself by not using the most cost effective means to grow their economy, negative externalities notwithstanding.

A significant part, when you consider that the tensions we've seen explode have existed for decades. As we saw in Egypt however, when people can't support themselves, they become desperate enough to finally act.

Sadly people in this part of the world seem to only see said events in either the rosy "Arab Spring", or some version of "Islam is fundamentally evil/unstable" sense.

The other parts of the problem deserve mentioned here, because they are extremely problematic and eclipse present environmental crisis and strategy.

Syrias civil war began after billions of dollars where somewhat clandestinely spent on fomenting violent revolution there - https://www.washingtonpost.com/world/national-security/lawma...

Libyas security collapsed after its infrastructure, including its world class irrigation system was bombed out under the guise of implementing 'no fly zone'

Solar and wind based energy production is not going to fully or even mostly replace our gas/coal burners because they lack constant and predictable outputs.

Also, we have neither infrastructure for storing power at this level, nor would it be economically feasible.

Hydro and geo-thermal are better sources in this sense, but neither are abundant and have their own drawbacks.

'- promote the use of electricity and natural gas in place of coal' - Only valid if the electricity is produced by means other than burning fossil fuels, otherwise you are just moving the problem up the supply chain.

Same way with electric cars, if the electricity is still being produced by dirty means, it is not all that impressive a reduction in poluttion or emissions, it's just moving the problem up the chain.

Not trying to sound defeatist or anything, it's just not a complete solution, still seem like band aid attempts by themselves.

Both real-world examples and simulations say it's possible, by combining different renewable energy sources, spreading them out geographically, and using large distribution networks, among others: http://reneweconomy.com.au/2016/dispelling-the-nuclear-basel...
Re:NASA Scientists Suggest We’ve Been Underestimating Sea Le... by XaYdEk on Monday October 31, 2016 @11:25AM (#12837605)
I feel like I might really dive into this conversation.

Technically feasible, yes, agreed. The simulations tell us this much, that at point T+x, we could have a green electricity grid, but you have to take into account the process of getting there and that means economics and politics. And there's a lot of half-measure that seem green, but just kick the can.

Ok, from the engineering side, the flexible, dispatchable sources will be required like I said, can't fully remove them. They can be hydro, which is clean and great, but it's not universally available and were it is, it's expensive to setup and tends to wreck local ecosystems. In most developing countries, the flexible source will remain what is already available most likely, at least in the short-medium term, and that is coal and gas. (this will be mostly for economic reasons)

... “renewable electricity generation from technologies that are commercially available today, in combination with a more flexible electric system, is more than adequate to supply 80% of total U.S. electricity generation in 2050 while meeting electricity demand on an hourly basis in every region of the United States.” ... That's why the time frame is 30+ years and that's in the US. What about less developed countries ? What's the time frame there ?

What I'm saying is: we will get there eventually, we really need to, our survival as a race might well depend on it, but it's going to be one hell of a ride, it's going to take a while and it will occur at different paces in different places.

And that you need a combined approach in terms of policy as well: investments, direct grants or subsidies for large producers for new and existing renewable plants and transmission infrastructure / public-private partnership projects (depending on your countries economic preferences), incentivizing individuals to go green (ex: subsidies on solar panel purchases by homeowners in Germany, government backed buybacks of old cars, subsidies for electric cars), better environmental standards, incentives for green certifications and an actual independent third-party validation of the companies that receive/offer said certificates, increased power to government environmental agencies (don't overdue it, point is not to shrug Atlas through punitive measures, but to get them to work towards going green), tax-breaks for companies that can prove low-emission is an option, but would probably be a bureaucratic nightmare, carbon-tax and myriad of other tweaks and measures.

And the 'Free Market' doesn't like any of this. Politics and economics, not just the greatest engineering challenge we have undertaken to date.

"lack constant and predictable" We can solve this with batteries, which we have so far not been able to succeed in to do at large scales. There has been some small scale success with liquid batteries, using cheapish elements. Which in theory is feasible to scale up.
Re:NASA Scientists Suggest We’ve Been Underestimating Sea Le... by XaYdEk on Monday October 31, 2016 @06:23AM (#12835560)
Technically yes, economically difficult for most nations, if it's approached at this level.

Germany has had an interesting approach to solar, where they subsidized solar panels for homeowners. I think it is the smarter approach because you incentives individuals to go green, rather than trying to implement a top down solution.

And even so, we will need to keep power plants on call for redundancy and high load purposes.

There is a video about peak power usage in England which I found fascinating (though this is a rather unique case) https://m.youtube.com/watch?v=slDAvewWfrA

It is a complex problem. As far as I understand, in the criticism to any work on climate change in the west (at least in the US) is that people are still debating if it is real or not, in the face of evidence; hence there's lack of political will. And, in countries like India or China, the criticism is that lots of people need cheap fuel to get out of poverty and imposing restrictions would impede that. Though, the per capita consumption is way less compared to countries like US. That said, I wouldn't say these countries are not doing anything. I can speak for India, for example, there is the Jawaharlal Nehru National Solar Mission[0] that is a goal to achieve 100,000 MW of solar power generation by 2022 and I see developments underway in many states in India. There are similar initiatives in other areas like Wind energy etc.

And, the defeatist attitude that no one takes it seriously, lets just do nothing and hope it works out is dangerous. As far as I can tell, the island nations will be the first affected, not to mention harsher weather, more storms, followed by massive shortages of food and water. I wouldn't be surprised if that leads to more wars than funding research and innovation.

Yes, the US' continued debate over whether or not this is even real is maddening. Climate change has unfortunately been sucked into the great maw of partisan bickering, to loosely quote a different Vox article on the subject; belief or disbelief is not based on facts, but a deeply rooted sense of identity. And so, due to our highly tribal nature and inability to feel sufficient empathy for those in out groups, the US will not have the majority political will necessary to stop this problem. Barring a series of technological miracles that give us a bevy of cheap, carbon-neutral sources of energy generation and storage, we are completely fucked. I'll probably be lucky enough to die before things get truly awful, but if I have kids, they and their own children are going to experience the horror of a collapsing civilization.

I vote for politicians that take this seriously. I try to discuss the issue rationally and calmly with skeptical friends. I am trying to get involved with a project doing research on nuclear fusion. Beyond that, I try not to think about the fact that I could be one of the last human generations. Walking around every day feeling like the axe is over the neck of our species, and we are too divisive, petty, greedy and apathetic to do anything is just heart-rending. I truly envy people who don't believe (or care) this is real.

> experience the horror of a collapsing civilization.

Wait, what? Is there any serious prediction of global warming causing collapsing civilization? How would that happen? Hordes of starving Americans abandoning their jobs and storming Canada? We've had big famines before and they were localized to the countries they happened in. Sea level rise won't swamp many places. We've got Syria wrecked by war and civilization is doing just fine in Europe despite refugees.

Population explosion used to be going to cause collapsing civilization. So was nuclear war. Global warming is the panic of our generation. Something else we haven't thought of yet will surely be gripping people's fear 2 generations down the line.

Re:NASA Scientists Suggest We’ve Been Underestimating Sea Le... by soundwave106 on Monday October 31, 2016 @11:58AM (#12837984)
The problem is the potential collapse of some civilizations. I have seen some serious predictions that the Middle East and North Africa in particular are vulnerable to potentially becoming uninhabitable in say 100 years due to too much extreme heat (https://www.mpg.de/10481936/climate-change-middle-east-north...).

Civilization overall will grind on regardless, but you've got to admit that just the Syria refugees alone threw a massive kink in European politics. A lot of the countries that are predicted to suffer the most from climate change already are fairly poor. So the question is how much could climate change contribute to political unrest?

I agree that it does no good to talk about climate change in very strongly apocalyptic terms. That's part of the issue in the US -- the largely politicized hype tends to frame this issue in almost quasi religious terms. Either you believe in an Impending Apocalyptic Doom That Will Kill Us All, or you believe in A Vast Global Conspiracy Scam Designed To Enrich Crooked Elitist Climate Scientists. While I think there's plenty of evidence for concern, I do think the evidence points more towards a slow creeping collection of issues more than any sort of mass apocalypse.

For instance, the state where I live (Florida) is fairly vulnerable to sea level rises. What this means is that any infrastructure with a 50 to 100 year horizon has to now account for the potential that sea level could be much higher in the future if you want to really be safe (see http://www.southeastfloridaclimatecompact.org/wp-content/upl...). I don't expect Florida to be wiped out by climate change related sea rise but consider how much of Florida civilization is by the sea, I certainly expect some pain points. For poorer countries with much less resources, the pain points might be a lot harsher.

China has 22 nuclear reactors under construction, they are also collaborating with nuclear power innovators, and building renewables. India is also building more nuclear and solar. Honestly, I wouldn't be worried about them, they are the superpowers of 21st century and will understand negative consequences of climate change to their era.

I would be more worried about US & Europe - Germany is shutting down nuclear plants, opposition of nuclear is strong everywhere in Europe, US has been very reluctant to participate in climate deals and has a lot of climate-deniers in power.

I live in Yunnan, southwest China, which is very close to India. Most of Asia's major rivers descent from eastern Tibet or its foothills in or close to Yunnan: the Brahmaputra (Assam), Salween (Yunnan), Mekong (Yunnan), Red River (Yunnan), Yangtze (Yunnan), Yellow River (Qinghai).

China has built huge numbers of hydroelectric dams, in fact this region is almost certainly the unmatched world center for hydroelectricity. It is also one of if not the most ancient center of large scale hydro-engineering, due to Dujiangyan.[0]

16 years ago when I arrived, there were very few such dams, and all at smaller scale, so the pace of change has been great. (IMHO Beijing has done an OK / not terrible job of balancing these energy/"national security" requirements with ecological protection efforts.) Also, foreigners are often unaware that e-bikes are the dominant form of personal transport throughout China already. In terms of long distance transport, China's ever-expanding railways (eg. permafost-floating railway to Tibet!) carry more freight than any other country's network, and they are lending assistance to neighboring countries (Laos, Myanmar) on similar hydro-electric and rail infrastructure projects.

Given these observations, I find it ridiculous to suggest that China is not doing its part. However, I do question the wisdom of allowing so many of its citizens to buy cars.

Belgium's reactor is old (1974) and was planned to be shutdown. To my understanding, nothing serious has happened there, the plant is just following normal precautions because of a motor failure. Isn't it rather encouraging sign that safety protocols are followed?

Furthermore, if people didn't oppose new reactors as vehemently as they do, there would be less pressure to continue lifetime of the old ones

Re:NASA Scientists Suggest We’ve Been Underestimating Sea Le... by icebraining on Monday October 31, 2016 @02:24PM (#12839547)
I'm not only talking about the latest event, there has been quite enough stuff: https://en.wikipedia.org/wiki/Tihange_Nuclear_Power_Station

And considering that the first reactor was designed to work until 2005, it's only natural that more parts will start to fail until 2025.

Furthermore, if people didn't oppose new reactors as vehemently as they do, there would be less pressure to continue lifetime of the old ones.

You're just reinforcing my point. If a government can be pressured into running a nuclear plant beyond its safety limits because it refuses to take the popularity hit of telling its citizens to choose an alternative, then that government can't be trusted to run any nuclear plant at all.

We're already making a lot more stuff than what is needed (consider half of food is thrown away as food waste). What economies are fighting each other about these days is not so much availability of resources, as being the one who gets to make and sell in order to produce income.

Morally, it matters who makes things. The countries with high GDP who are responsible for the current extra CO2 in the atmosphere could always (you know, in theoretical fantasy-land) help out to make sure others produce as efficiently but reap the benefits. Instead of using the argument you make to pull up the living-standard ladder behind them.

This is what the OP said. I honestly don't get it, then why is India's (and China's) responsibility for climate change dragged in whenever the topic of climate change is brought up. Is it because, as you mentioned India has ~16 times less CO2 emissions (per capita, but still way less than US) and ~15 times less GDP?

Isn't there a fair responsibility to spearhead dealing with climate change problem when you are polluting more and have more resources to deal with the problem. While India and China, having their own problems are making efforts in this direction and US is still dealing with denial, conveniently.

Re:NASA Scientists Suggest We’ve Been Underestimating Sea Le... by awi on Monday October 31, 2016 @06:52AM (#12835669)
That is definitely not the problem. And that way of thinking is what leads to despair and helplessness, because we will never stop making and consuming.

Apart from a very few things (cement, steel, ammonia), producing things does not directly release any C02. What we need to do is stop burning fossil fuels to produce and consume energy. And that is already happening now. The biggest question is how fast can we make the transition and how much have we already fucked up.

Re:NASA Scientists Suggest We’ve Been Underestimating Sea Le... by dagss on Monday October 31, 2016 @07:07AM (#12835732)
You forgot meat, which stands for 10% or so of CO2 emissions [1] (and that isn't needed at all, compare meat consumption in the west with global average). And I'd consider "travel" a product too, I'm sure it factors into GDP which was the metric under discussion.

You are right, the biggest question is how fast we can make the transition. In considering that question, you can't dismiss lifestyle changes (=current overproduction and overconsumption) as a tool a priori, and say that only options that don't affect lifestyle can be considered.

Consider the lifestyle changes done by a population during a war. A lot of the production and consumption today happens so that people have a workplace to go to, not because it's actually needed, as in a physical necessity.

(I am not sure what you mean by direct vs indirect emission or why it matters; but the primary purpose of reducing production would of course be to reduce energy use, because one is not able to switch over to green fast enough.)

Re:NASA Scientists Suggest We’ve Been Underestimating Sea Le... by awi on Monday October 31, 2016 @08:27AM (#12836092)
No I didn't forget meat. Meat production does not directly put carbon atoms into the air (forget methane for a second). That is what I mean by direct emissions. When we decouple energy from carbon, the amount of greenhouse gasses produced by agriculture changes. The problem with such calculations you refer to is that they assume the current rate of CO2 emissions per unit of energy produced/consumed. When we reduce that number to zero, which we will, those calculations are useless. (Farming is a little more complex due to deforestation and methane, but still the argument stands.) This is whats wrong with people who try to calculate MPG equivalents of electric cars based on the current emissions from power production. Electric cars do not release any CO2, period. Power production currently does, but we will fix that separately.

We need to apply system level thinking to this problem, what is a strategy that will lead to zero (acceptable) emissions? We need to focus 100% on that strategy. I believe lifestyle changes based on moral arguments are a distraction due to the following reasons:

1. Its completely unrealistic to change behaviour at that scale

2. Even if successful the effect is only a minor delay, not an actual solution. Any gains due to consumption reductions is more than offset by growth.

3. Focusing on such things may be counterproductive. First by creating opposition to the entire climate change agenda, telling people to change their way of life makes them oppose it any way they can, including denying the problem completely. Secondly we need to stimulate demand for zero emission technologies, reducing consumption is counterproductive to that.

Given infinite clean energy you can always harvest back CO2 from the atmosphere, so I am not sure why you make the sharp distinction between direct and indirect. Yes, I agree that at the end of they day it's only about the world's energy consumption and energy sources. So I'm just saying "stop wasting energy" then.

The point about lifestyle changes wasn't moral BTW, point is they should not be dismissed if they buy time, in trying to make exponentially growing green energy overtake the exponentially growing problem with CO2 emissions. You are asserting such changes are unrealistic, in which case it is of course no point in arguing for them. (But if you look at WW2 and the oil crisis in the 70s there were large-scale lifestyle changes being made, once the crisis is easily visible and understandable.)

It seems like we need everything that can be thrown at the problem (and probably even then hopes are low). Do you believe any focus on reducing (or rather, stopping further increases of) energy consumption is actually hurting a move to clean energy?

I... uh.

Firstly, the number cited was ~10 times the CO2 output per capita, not ~16.

Secondly, it doesn't follow that GDP production in a primarily high tech, services, IP based economy should track the CO2 behavior of a different sort of economy. It's entirely possible that we're producing far and away more GDP and wasting CO2 production needlessly. (In fact, out GDP multiplier is 1.6 times higher than our CO2 multiplier, hinting that the two are at least partially decoupled.)

I think you might be over estimating how much of the US economy is IP based or high tech.

Google tells me 6.7M people work in tech out of 127M people with a full time job. Roughly 4%? Sure, the GDP per worker is higher, but suffice to say most of the GDP output of the US isn't due to sexy new low CO2 jobs.

Edit: Tech is ~7% of US GDP.

My numbers are based around the idea that the US has a 1.6/20.8/77.6 Agriculture/Industry/Services breakdown, while India has a 17/29.7/45 breakdown, and that 40% of the US GDP doesn't seem to depend in any way on things that would produce much CO2 (compared to say, heavy industry) -- real estate (not construction), finance, health care, information, entertainment, corporate governance and education. (That's not counting another 15% unspecified government spending, which likely includes a substantial amount of non-CO2-producing expenses, likely pushing that number up to about 50% GDP.)

Similarly, industry-volume-for-industry-volume, the US should be more efficient in production, meaning that it should use lower CO2 even with the same level of industry.

Which is what we see: the US does use less CO2 to produce more GDP, precisely contrary to what the argument supposes (that they're exactly correlated).

I'm not saying that the US does make poor use of its CO2 emissions, merely that the argument I was responding to failed to show either direction -- the argument it made was fundamentally unrelated.

Ed: To put math on it -- the US is somewhere between about as efficient as India and less efficient than India, depending on how exactly that 40% aligns with actual CO2 production and how closely that 15% aligns with CO2 production. In the case of the 40%, the US is within rounding of not wasteful. In the case of 50%, the US is somewhat less efficient and probably is wasting CO2 production.

The problem with your analysis is that a) it was simply wrong about the numbers, and had a 1:1 CO2:GDP relationship, when the numbers don't bear that out (and hence didn't account for my objection) and b) it supposes a fact about comparing CO2 production to GDP that isn't true, because the composition of economies varies substantially.

I wasn't saying you were wrong. I was saying your argument was bullshit.

Like weapons for export to Saudi Arabia to level Yemeni towns to reduce CO2 emissions, for example.

Suggesting China and India aren't doing enough is at best a form of colonialism and at worst racist. Both produce far less CO2 per capita than western countries. The west has an interest in stunting their industrial growth not out of any sort of altruistic concern, but because they fear competition. Regardless, both India and China are embracing renewables and clean energy at a faster pace than the west, they're not only the future economic powerhouses but also more progressive environmentally.

If we can avoid nation-state-thinking then yes. We can't; the basic architecture of any agreement right now must use the nation-state as signatory.

That is a sale that cannot be made. It looks like a transfer of (mythical) carbon credits from the US to other nations.

(a) China and India are doing the best they can, as highlighted by several links in this thread. I don't know where you get this information that China and India are "doing nothing". Please share your source. (b) "I say let it happen", "No one is going to take it seriously until its to late anyway ". Do you see the irony?

Do you have any number to show that developed nations cannot put a dent on global warming? Whatever I could gather in 5 minutes points otherwise [1]. Even if you believe so, they can still help by: (i) Using their technical expertise and money in helping developing countries develop and deploy green technology. (ii) They are the consumers of most of the manufacturing output. They can set stricter rules on ecological impact of produced goods. They can set local laws that will not allow companies to buy from polluting industries.

it is actually in the west's hands, where most tycoons and climate change deniers reside.
