As a European this is the main fear I have during this election. 4 more years of inaction from the government of one of the biggest polluters in the world will really bite us in the ass. Not that I’m super proud of how we are doing in my country, but it can’t get worse.

>4 more years of inaction from the government of one of the biggest polluters in the world will really bite us in the ass.

But that's not the case. America is reducing its emissions greatly by shifting from coal to natural gas (which mirrors what Germany is doing, for example). Coal is ostensibly dead in US. If you look at the charts from Wikipedia [1][2], you'll see the US has cut emissions at about the same rate (or faster) than Europe. That trend will continue. So what will Paris actually do in practical terms?

The problem is that after transitioning away from coal, there isn't a clear answer about the next step. Renewables are not a panacea and may never be able to power a modern economy as they will probably always require fossil fuel baseload ... not to mention that because renewables are a diffuse energy source, they require HUGE land areas which makes no different for CO2 emissions, but makes a huge difference for environmental collapse.

The US has majorly been transitioning to both natural gas AND renewables.

In fact, practically the only facilities being built for the last decade have been wind and solar and in massive quantities. If you look in the generation queues of the various RTO/ISOs (organizations that manage which units run and at what level for large parts of the grid) the only thing expected to be built is even more wind and solar along with storage. Multiple GW of wind capacity is being added each year, so it isn't slowing.

Why is this happening? It's complicated, but it's basically economics at this point.

What problems do we face? Well, sometimes wind and solar aren't available. You can solve this in three ways. The first is to have thermal generation respond when the wind/solar dips. This can be tricky as thermal generators (outside of natural gas) weren't designed to move that fast. They were designed to run near max for most of their life. Natural gas peakers are more effective here. Another option is storage, which can hold you over until you get more wind/solar again. However, we would need a massive amount of storage built for this to be effective. A third option would be to increase demand response at the industrial and customer level. Meaning, power isn't generally expected to be 100% available in that scenario. If there isn't enough generation capacity, those that aren't willing to pay the high prices are shut off (or something along those lines). That is generally how supply/demand is supposed to work anyway, but practically speaking, the demand doesn't participate today. In actuality, I expect a combination of all of that to become common place and it is what the Federal Energy Regulatory Commission has been pushing for.

Re:U.S. Exits Paris Climate Accord by Retric on Wednesday November 04, 2020 @09:05AM (#24989133)
The most economical option is it have a massive oversupply of wind and solar as their significantly less expensive than any alternative.

You can model this as (cost per kWh of cheapest alternative) / (cost of rentable per kWh) = marginal oversupply you want. So, if hypothetically Solar was 2c/kWh and peaking natural gas was 6c/kWh then you would want to add more solar until 3kWh of new Solar only offset 1kWh of natural gas with the other 2kWh being wasted.

Which does not mean 2/3 of total solar energy would be wasted. Further, storage and energy markets also complicate things. However, it does illustrate why you want an over supply of the cheapest option even if not all of it gets used.

Re:U.S. Exits Paris Climate Accord by 7thaccount on Wednesday November 04, 2020 @09:12AM (#24989195)
There is a problem with the massive oversupply idea though. It assumes wind locations are fairly randomized and I don't think that is entirely true. Meaning you can build more in area "x", but if it isn't blowing a quarter mile away, it probably isn't blowing near you either. Think of this more as a conceptual argument. Now oversupply would help if it's just blowing a little bit I suppose.
Re:U.S. Exits Paris Climate Accord by Retric on Wednesday November 04, 2020 @09:19AM (#24989254)
It doesn’t matter if supply sinks up 1:1 because demand doesn’t. If solar always produced the same energy evenly form exactly 10AM to 6PM EST for some parts of the day you could have an over supply of solar and at other parts of the day you would have an under supply. The same is true on the weekend vs weekday. Even seasonal power demand is less in spring and fall than summer and winter due to heating and cooling.

Though when selecting individual locations for wind, different locations favor different time of the day. And of course solar output varies significantly east/west and based on local weather conditions. That all gets modeled ahead of time and in practice get reflected in market rates.

Re:U.S. Exits Paris Climate Accord by mmm_grayons on Wednesday November 04, 2020 @09:19AM (#24989251)
Exactly. The big blocker to a full-scale rollout of renewables is storage and it has been this way for years. We're still facing the problem of the duck curve, which has been known for years: wind and solar peak at the wrong times because peak load is actually in the evening.
Re:U.S. Exits Paris Climate Accord by marcosdumay on Wednesday November 04, 2020 @09:37AM (#24989392)
The oversupply is coming, it seems almost inevitable by now. But a massive oversupply requires a large fall on the prices of electricity conversion and generators maintenance.

Even then, I do really expect a category of "peak demanders" to appear soon (storage is one kind, but there are other things one can do with intermittent almost free electricity). That will help increasing the spare capacity.

Re:U.S. Exits Paris Climate Accord by Retric on Wednesday November 04, 2020 @12:22PM (#24991009)
It’s going to be interesting to see what happens if daytime rates start to consistently dip below current night time rates.

I suspect an outgrowth of oversupply is storage will ramp up based on consistent access to very cheap rates. It makes a huge difference if you’re paying 0.4c/kWh or 4c/kWh to charge, especially when storage is significantly less than 100% efficient.

Re:U.S. Exits Paris Climate Accord by macspoofing on Wednesday November 04, 2020 @11:40AM (#24990577)
And where are you going to store this oversupply?
Re:U.S. Exits Paris Climate Accord by Retric on Wednesday November 04, 2020 @12:28PM (#24991076)
My point is you don’t need to store the oversupply. Grid spot prices hitting zero mean you can just dump the power as that excess is in effect worthless.

That said, consistent very low prices will likely result in someone using most of that power for something even if the power plant operators aren’t making money during that period.

I don’t think any of these solutions are viable to prove we can be reliant on renewables, and this one especially would not resonate with a populace.

Just at a consumer level, think of everything you use power for on a daily basis. It’s a cornerstone of modern life, and you can’t expect society to backtrack.

This already occurred back when renewables were nothing more than the fantasies of tree-hugging hippies like my mum.

Before I left the UK, the flat I lived in had two electricity rates, with the night rate being significantly cheaper then the day rate [0]. This meant the water heater and the (electric) storage heaters [1] were powered at night, when schools and offices used no power.

Re:U.S. Exits Paris Climate Accord by makomk on Wednesday November 04, 2020 @09:37AM (#24989383)
That has the advantage that the drop in power demand during the night is extremely predictable, so everyone knew that they could reliably get cheap power for heating just by shifting their demand by half a day. (Also, the UK had and still has a fairly large nuclear power fleet which generally runs full-out 24/7, and this kind of demand shifting is a good match for that.) The trouble with renewables is that a lot of the drops in supply are both unpredictable and relatively long, which makes them hardre to deal with.

Also, storage heaters are a real pain to deal with. They're inefficient and not very controllable in terms of the amount of heat they produce.

Not so; when the problem is bad weather rather than the diurnal cycle, even weather forecasting gives more forewarning than emergency stop buttons in power stations, and (given the geographical distribution) the change itself is smoother. On the scale of a continental grid, do you even need to care about anything besides diurnal storage/demand-shifting (as preferred) and seasonal issues?

Re:U.S. Exits Paris Climate Accord by Al-Khwarizmi on Wednesday November 04, 2020 @10:55AM (#24990133)
In my country we already have a system where the price of electricity fluctuates hourly depending on supply and demand.

The result for individuals: many people just subscribe to a flat rate from the electricity companies to avoid the uncertainty and pay the same predictable price each month (but of course, this predictable price comes at a significant markup with respect to the "free market" price). The rest of us go with the fluctuating price but just don't bother, because we are not going to spend substantial amount of time every day looking at how the prices evolve to decide when we turn stuff on or off. So we just read the bill every two months, not even making an effort to understand it, grumble a bit and go on with our lives. I suppose there may be some people who actually try to optimize, but I don't know any - from what I know, people short on income tend to go with the flat rate because they can't afford the uncertainty.

I don't know how it works in industrial applications. I do know that some industries (e.g. steel) complain about the fluctuating prices because they operate 24/7, and basically they reaction is that if the government doesn't subsidize their electricity bill, they'll just close and go to some other country. So my guess is it's not really working either.

You say that like it's true, and it's not. Anyway, the climate doesn't care. Human emissions will reach equilibrium with what's compatible with life on Earth, one way or the other. Figuring this out is preferable to massive loss of life and degraded standards of living for the survivors.

I find it particularly telling you exclude nuclear as a baseload and specify it has to be fossil fuel baseload.

Re:U.S. Exits Paris Climate Accord by macspoofing on Wednesday November 04, 2020 @11:42AM (#24990600)

They didn't. They replaced natural gas in one specific use-case, namely to provide grid stability. Those batteries (no batteries) are capable of bridging renewable variability.

When the wind is blowing. If the wind isn't blowing, you're not getting any power and you're going to have to fire up those coal/natural gas plants.

>when their new synchronous capacitor projects are completed they won't need stand by gas power plants.

How much power can these 'synchronous capacitors' store, and for how long? Can they even store enough to power a small city (~250k) for more than few mins? Let me spoil something for you, there is no battery technology that can scale to run a modern economy and hard industry. Not now, and not upcoming. If you have favorable geography, you may be able to do pumped storage, but that's about the best you can do.

Keep in mind that EVEN if you miraculously had something to store grid-scale power over a long-term, you need to greatly overprovision renewables because those 'batteries' need to be charged (with lots of energy loss) during peaks enough to bridge daily, seasonal and inter-year variability. And of course, land-use requirements for renewables is MASSIVE (from mining to deployment to decommissioning) - so renewables are very heavy on the environment. They aren't going to work.

There's a reason why no developed region relies on renewables without either fossil fuel backup (or if geography allows, geothermal or hydro). There's a reason why Germany is spending billions to build pipelines to ship natural gas from Russia for decades to come. What do they know about renewables, that you don't?

Re:U.S. Exits Paris Climate Accord by adwww on Wednesday November 04, 2020 @08:50AM (#24989001)
This is what the UK did a number of years ago. At the time we got a lot of praise for dramatically cutting emissions.

The problem is, that change didn't effect anyone negatively, and thanks to cheaper gas imports it was essentially free.

Now that we are off coal, future cuts are going to be a lot harder.

Unfortunately there are methane leaks in the systems, and it is quite possible that when accounting for the methane releases, natural gas has equally bad climate effect (emissions of CO2 and CH4 combined) as coal.

Re:U.S. Exits Paris Climate Accord by thehappypm on Wednesday November 04, 2020 @09:17AM (#24989232)
It's a step, though. Methane is inherently unstable and won't stick around in the atmosphere forever once we stop emitting it. CO2 gets absorbed into the ocean very slowly and with acidification as a consequence.
Re:U.S. Exits Paris Climate Accord by TeMPOraL on Wednesday November 04, 2020 @09:26AM (#24989302)
It's important to say explicitly what "not forever" is here. Half life of methane in the atmosphere is 9 years[0]. Then it decomposes into CO₂ and water; the latter is suspected to be a potent greenhouse gas at that altitude[1].

Good point. CO2 equivalents are a better measure than CO2.

I think fixing leaks is an easier task than reducing the coal CO2 footprint. We'll have to figure this out somehow anyways, because a lot of methane will be going into the atmosphere from thawing permafrost, both on land and in the seas.

Re:U.S. Exits Paris Climate Accord by Qwertious on Wednesday November 04, 2020 @10:18AM (#24989745)
It's not easier - as I understand it, the leaks are tiny amounts along the entire length of the pipelines. Getting an absolutely perfect seal is something that's expensive to do, whereas in theory the CO2 footprint of coal is concentrated and therefore much easier to capture.

In practice, doing either of those will spike the price of the energy, and the only reason to use them over renewables is their being cheap, so it won't happen.

Re:U.S. Exits Paris Climate Accord by FrojoS on Wednesday November 04, 2020 @09:13AM (#24989205)

Re:U.S. Exits Paris Climate Accord by freeflight on Wednesday November 04, 2020 @09:46AM (#24989483)
The main reason for German gas demand is that a lot of the residential heating still works with gas.

But the gas infrastructure synergizes extremely well with a shift to a hydrogen based energy economy, as is not just the goal in Germany, but pretty much an EU wide ambition [0].

It has nothing to do with the German nuclear phase-out that started in the early 2000s, just like European reliance on Russian resources it not anything new, nor is it bound to change, it's the consequence of geographical proximity and thus realpolitik.

Particularly considering the alternatives: LNG shipped from the US to Europe in tankers is an net-energy negative. It would be a pointless and expensive exercise of creating even more pollution all for the sake of satisfying US foreign policy ambitions to antagonize Russia and keep it as separated from the EU as possible.

Yeah, there is a slight increase in natural gas over the years (with large fluctuations), while coal is in slight decline. By far the largest share of the nuclear phaseout has been replacing it with renewables.

This is completely fallacious. There will always be outliers but the overwhelming majority of power needs, both residential and commercial, can be addressed with renewable energy and battery solutions.

> not to mention that because renewables are a diffuse energy source, they require HUGE land areas which makes no different for CO2 emissions, but makes a huge difference for environmental collapse.

Can you cite anything backing that up? Hydro electric does dramatically impact the environment but other renewable sources have no such impact. Wind is negligible despite the fanatic ravings of one fat orange lunatic who doesn't like it's aesthetics. Solar is easily deployed on rooftops and along transit corridors which has zero impact. You don't have to consolidate all the renewable energy sources in one location.

I have a solar array that covers less than half my roof, produces 1.5x my energy needs annually, it stores reserves in a battery, and back-feeds excess into the grid. The cost to operate the array is less than the cost of grid power, and my excess production results in a payout from the power company.

The excess production from residential and commercial arrays can be captured and distributed to outliers who are unable to directly leverage renewable energy and completely offset the need for polluting energy sources.

How about, at the very least it is symbolic of the fact that the US will fully take part in one of the most important global programmes there is. That it will set targets and be transparent, reporting on its efforts to reach those targets. It will share know-how and expertise with countries that are trying to solve a problem that is an existential threat to civilisation.

And if, as you suggest, the US is actually beating the progress it needs to make to keep global temperature rise to within 1.5C, then that's great - it can get the global plaudits it deserves, with no further action needed.

Of course a country of 1 billion people, like India or China, is going to produce more emissiosn than a country of 330 million, in total, even if each of the smaller country's citizens produces about twice as many as the citizens of every other country in the world.

> why it isn't talked about more

Because reducing energy use reduces quality of life at constant dollar income (at least medium term), and reduces economic growth (energy's an input in all economic activities), with all the social negative consequences that produces. It's a third rail, politically. No one's going to get elected by saying "your children have to live worse than you".

The Western world is already (slowly, over decades) reducing this (look at per capita energy use dropping nicely since the 90s), and there's significant pushback even at this rate (gillets jaunes, cost of living protests). All future energy use growth is elsewhere (Africa, China, India) with no plans to stop and if the Western world tries to impose their views on them, it'll look a lot like neocolonialism for environmental reasons.

Um, this is already happening, in a big way.

Cars are more fuel efficient than ever. I own an SUV and average 30.1 MPG. Imagine that in 2000. Light bulbs are overwhelmingly LED these days. New homes are much more insulating than ever. Smart homes are less wasteful.

Re:U.S. Exits Paris Climate Accord by freeflight on Wednesday November 04, 2020 @10:08AM (#24989664)
Tho it seems like a lot of these increases in efficiency we traded-off by being more liberal in using the tech; Light bulbs are overwhelmingly LED these days, but we now also stick LEDs in all kinds of places where a light bulb would never have fit/made sense before.

Smarthome might theoretically work, but as of right now most people are just throwing even more IT and IoT devices, constantly drawing power, into their homes. As these come from a myriad of different vendors, there is no unified platform to utilize and manage all that for electricity efficiency, it's just going on, drawing additional power.

It's so obvious I wonder why it isn't talked about more

But is it obvious? Let's say that fusion becomes commercially viable and vast amounts of emission-free energy become available cheaply. Would reducing the usage of it still matter? I would say the driving factor is the side-effects of energy production by current methods, not the energy itself.

> It's so obvious I wonder why it isn't talked about more

I think this is because energy consumption is directly related to our ability to manufacture things, and the ability to manufacture things is directly connected to both wealth and military power.

(I’m half-remembering someone else’s explanation, so I assume this is an oversimplification).

Re:U.S. Exits Paris Climate Accord by TeMPOraL on Wednesday November 04, 2020 @09:18AM (#24989242)
Because our energy consumption is ultimately tied to the exponential growth of the economy. Even if everything around us would become 10x more efficient - which already would require many scientific breakthroughs - that's just multiplying the exponential growth curve by a constant factor of 0.1. A little bit of relief, but it fundamentally doesn't change anything.

And that's ignoring the reality that if you make something 10x efficient, it tends to become used more - sometimes much more, cancelling the gains. Our economy is self-regulating; altering one factor only makes all others readjust to compensate. Permanent change will require more complex approach.

Energy efficiency is definitely a very important part of dealing with climate change, but it isn't a silver bullet.

We need to get off this exponential! Any modification of Capitalism is painted as an attack on basic human freedoms so that the rich can go down with the ship, rather than pass it on for the rest of humanity and the world.

How do we change what we optimize for? Because it currently isn't working.

Solar is great for marginal additional output, but to make it useful as a primary energy source it requires massive investments in storage technology. Solar doesn’t work at night or on cloudy days, so you still need other power sources. At least as long as storage solutions are rare.

The biggest issue with the Paris Accords is that China did not commit to begin any restrictions until 2030. ...and since they are both the world's largest CO2 emitter and world's fastest growing CO2 emitter, the Accords became a corporate strategy to just move more manufacturing to China (and other non-limited countries).

Frankly, I think the Paris Accords does more harm than good by giving anyone the notion that we were solving the problem.

The optimal strategy to combat Global Warming is to bring manufacturing back to the EU and US and regulate emissions strongly.

Re:U.S. Exits Paris Climate Accord by dalbasal on Wednesday November 04, 2020 @08:47AM (#24988976)
Ultimately, both arguments are true.

Developing nations have a claim. It's deeply unfair that wealthy nations who have emitted a lot of carbon get permission to keep emitting more as a result. But also.. if developing nations fully stake this claim by increasing their emissions or even flatlining then the game is lost.

This is the problem with thinking in absolutes. The alternative is making some concessions and moving forward regardless because of belief in the mission. Europe is already in the same per capita ballpark as china. If the US/Australia/etc had gotten themselves near this per capita level, the politics of developed/developing economies would have softened somewhat. The fairness issues aren't as sharp once emissions are similar.

Realistically, we are not politically structured (as a world) to deal with carbon reduction well. Nationalism is the dominant paradigm both structurally/politically and ideologically. It's a weak paradigm for global action.

I emphasize the politics over the economics, though obviously both intertwine. Long term, there are economic upsides as well as downsides to carbon reduction. As a blind (long) bet, I'd always bet on new energy paradigms being a good thing. The long tail upside is especially interesting. Within a functioning polity, that's something you can work. The world isn't.

Meaning them committing to doing something 10 years doesn't mean they will do it at all.

We clearly don't really care about climate change or stuff like this would be about taxing pollution through tariffs and other means. Rules like this just move the manufacturing and thus pollution to different countries. Which is pointless when the goal is to reduce climate change.

China has a lower level of pollution per capita than many other countries, including the US.

Think about it, they have more people than the US, Canada, the EU, UK, Russia and Australia combined. That's some major need for energy, which everyone else just blames on "China".

I think they're doing pretty well in comparison.

While I'm at it, I need to mention their one child policy basically stopped hundreds of millions people from ever existing. A whole lot of pollution that never happened. Something no other country has done, and I think China should have some recognition for that.

Wouldn't it be better to instead let the developing world leapfrog fossil fuel energy generation, and go straight to renewables (and possibly nuclear)?

All the new plants Chinese government approve to build now are super critical coal plants. These are the most efficient ones. The gov also regulated older coal plants to retrofit NOx, SOx, pm2.5 treatment equipments. China doesn't have much oil and natural gas but has a lot of coal. So for energy security at the present moment they kinda have to still use coal. They already import lots of oil for transportation and industrial use. But at least they are doing something to reduce coal impact which I think is better than nothing. The air quality issue is known to every Chinese person now, so the government has a lot pressure to improve it. The gov also have good strategies to drive solar adoption. Like if farmers to build solar panels in their farm fields they get tax breaks and they earn money from selling to the grid. And with the price of solar and electricity rate, it's a profitable business. So far it's being working. Solar installation is growing year by year. The gov also pushed to build a few extreme high voltage DC transmission line from the west to the east to transit the renewables generated in that region to the east where energy is demanded. The China National Nuclear Corporation has a mandate to research and build new nuclear technologies. It's now building a number of gen 3 nuclear reactors and they are researching gen 4. A number of electric car companies are taking off in China. Big Chinese cities are already clogged by ICE cars. To buy a car you need to take a lottery for licence plates. In these cities they have separate lottery group for new energy vehicles, which includes hybrid and pure electric vehicles. The gov is now giving equal quota for both groups or more for NEVs. So a lot of people are buying NEVs just because the lottery line is shorter. These people probably won't consider a NEVs before. But companies like Tesla and nio is making great cars too and that is driving demand as well. Some cities are also transition public utility vehicles like buses to electric. Also the high speed rail system and subway system also has major environmental benefits. HSR moved 2.35 billion people in 2019. I think thats amazing. Thats 2.36 billion trips on electric transportation, and not on cars and airplanes. So without the massive investments and foresight to build the HSR, there will be more cars clogging the environment and oil used.

But how? The manufacturing that went overseas did so for cost reasons. If you make it even more expensive then there is even less incentive to have it here. Dismantling the economies of the east from afar is not an option for a ton of reasons.

Re:U.S. Exits Paris Climate Accord by laurent92 on Wednesday November 04, 2020 @08:10AM (#24988657)
It is also based on the idea that any human deserves the same emissions. Of course, at first level, it is legitimate. However, a country which doesn’t want to pollute should rather choose to keep their population low, through various incentives including cost of life. It would set them back on the economic power, but that may be a choice: Better lifestyle for fewer people.

In the current system, however, a country who keeps their population low will have small allowances; It clearly incentives overpopulating its land. This inverse-incentive effect may provoke countries into doing nothing against evergrowing population, keeping cost of life too affordable, and thus, ensuring that the next generation will be overpopulated, and thus, extenuating the land.

The issue is rather that nobody really brings up any valid alternatives when they disagree with Paris.

Saying "bring manufacturing back" is not an valid alternative, it's wishful thinking that ignores how this current situation came about, while offering zero actual actionable advise how to reverse that development and fix the problem itself.

Manufacturing went to China because of laxer regulations there making it more cost-effective, how are you gonna convince it to come back to the US and EU with even harsher regulations?

It's not really that obvious because an escalating global trade-war is rarely good for anybody, and tariffs only end up costing the consumers.

That's also why even after years of Trump tariffs on China, and all kinds of other countries, there was still no major shift of manufacturing back to the US.

> This is a very very easy problem to solve... once we wean ourselves off the cheap tat China produces

No, because companies that want to employ Americans can't compete with companies that want to employ Chinese, because it costs less to employ Chinese.

In other words there are externalities (polluting the global environment) that aren't priced into the cost of labor when you're comparing the two countries. Tariffs and similar things can help price in that externality.

Cleaning up the US would probably mean outsourcing more carbon emissions to the rest of the world. Outsourcing is the primary way the developed world has "cleaned up" so far.

The only way we will substantially reduce CO2 emissions is to develop a source of energy that is carbon-free (or incredibly low carbon) and cheaper and easier to deploy than coal and gas. Reductions without that are politically impossible. There is no other way. If we don't succeed in doing so, we should plan for significant climate change as a certainty and begin planning our adaptive response.

That is not true. The other ways are:

1. Reduction of energy use per person.

2. Control of population growth - at the very least, stabilizing the Earth's population and theoretically a reduction.

3. Using Energy sources which are low-carbon, but expensive and/or difficult to deploy.

of course your way makes it a lot _easier_, but since reduction of greenhouse gasses is necessary regardless of the availability of a convenient energy solution, these are also relevant, and gradually are becoming necessary.

By the way - (1.) is already progressing relatively well in lots and lots of countries.

No, it's more like moving your cooking and garage wood shop work to someone else's house, taking the results home, and leaving the mess.

The dirtiest parts of the production chain required to sustain our lifestyle have largely been offshored, not only because of cheaper labor but because less developed or more totalitarian countries will tolerate the pollution.

Yes these things can be done cleaner, but that adds cost that people don't seem to be willing to pay.

Americans want all of: (1) high paying good jobs, (2) clean air and water, and (3) cheap manufactured shit. Sorry, but it's worse than a trichotomy. If you pick 3 you have to pass on 1 and 2.

If we want 8 billion people living in comfort, we need more energy. As always, I think we should have been building more nuclear plants back in the 90s. And again in the 2000s. And the 2010s. Maybe now we can go wind and solar. But we need lots of something.

I’m really not sure this is the case. For example, we know that we have far more than enough capacity to produce food for the entire world, we just simply don’t do it.

Of course, Americans are very wasteful, and we can’t scale that amount of wastefulness to the entire planet.

We have enough fossil-fuel-dependent capacity to strip-mine soil to feed the entire world. I'm not sure if we have enough capacity for sustainable food production, and even if, the methods, technologies and supply chains aren't there (and won't be, as long as they have to compete against modern agriculture).

The things you'd need to do to get the world to accept a definition of "comfort" that doesn't include eating meat (vegan definition) several times a week, living and working comfortably climate control buildings and access to a wide array of consumer products would not be pretty to put it mildly.

Making people's standards of living go backwards make them shoot you.

Holding down people's standards of living makes their kids or grand-kids shoot you.

Policy sticks are a time bomb. Social solutions (convincing people to behave in a way that reduces their environmental footprint) only get you so far. We need technical solutions (more efficiency in the entire economy) such that people can eat fish or beef and drive in cars (or have access to functionally equivalent or superior analogues) at lesser environmental cost. The "western lifestyle" (moving target, I know) needs to scale because even if the west manages to reduce consumption enough to have a good impact the masses in developing nations are certainly not going to settle for the status quo let alone a reduction in consumption.

You need less people, fundamentally. The total fertility rate is declining across the world luckily (except a handful of countries and Africa) [1], but everyone around now is going to have a rough ride until equilibrium is reached (sometime after 2100). Can’t grow your way out of resource exhaustion (renewables excepted).

We can also just have fewer people: If you lower infant mortality, educate women and give them access to family planning, all evidence suggests they will choose to have fewer children.

It's much easier for the planet to support a high standard of living for four or six billion people than eight or ten billion.

Re:U.S. Exits Paris Climate Accord by throwaway0a5e on Wednesday November 04, 2020 @08:16AM (#24988701)
I agree with the premise but the fundamental question is whether we can get from the current status quo to a hypothetical sustainable equilibrium without the squeeze of climate change causing a ton of pain along the way and in a manner that is at least kinda sorta ethically tolerable (i.e. genocide and/or picking who gets to reproduce are not options on the table).

The developing world population growth is peaking soon or looks to be. But standards of living growth there is exploding so their impact will peak at some unknown point in the future. The already developed world is staying roughly static in terms of population and environmental impact per person is declining slowly there. To use a metaphor, it's like we've got a half full bucket, are very slowly siphoning out water and are also half way through rapidly pouring in an unknown amount of water. Will it overflow? Nobody knows. It would be prudent to try to remove more water and pour in less though.

Edit: Anyone care to tell me why I'm so wrong? Is genocide back on the table or are people just annoyed that this is a hard problem with no shovel ready silver bullet?

Aggressive population control should be given high priority, yet declining population growth and fertility rates are always depicted as negatives in Western countries. In Europe many countries still have incentives to boost fertility.

It's high time we give up on the fantasy of an ever growing population as a ponzi scheme to boost the economy and finance public spending. We need to face the reality that we ought to have at the very least a stable population and reorganise society accordingly.

In relation to developing countries, any healthcare-related aid should be conditional to implementation of birth control policies.

Globally we really should have a target to reduce population by a few billions if we want to all enjoy life in comfort (~Western country level) on a thriving planet.

Edit: Judging by the reactions, the penny has not dropped yet for some... Hopefully it will before it's too late.

This is not true. It is possible for 8 Billion people to live in comfort (of course, for a reasonable definition of comfort, which isn't typical US lifestyle at the moment), with the amount of Energy produced right now. _If_ production and distribution, political and economic structures, transportation and habitation systems etc. were to change significantly.

"We want" is language that hides reality. Who wants this? How many people?

As the Trump election (and many other elections around the world) show there is no "we want". Different people want different things. Sweeping that fact under the carpet again and again leads to Paris type meaninglessness. Paris fails because there was never any "we".

All the narratives of fear and blame, guilt and shame that have been tried did not make a dent.

Those who want to do something will do it and those that don't want to wont.

Reconcile to that reality and things will actually move forward.

The world doesn't actually care if you don't want other people to live as comfortably as you, because it's gonna happen either way, no country in the world is going to stop pursuing a better quality of life.

From the perspective of actually fixing the problem (which takes capital investment), the most pertinent graph would be per unit of GDP.

It acts as both an efficiency measure as well as an indication of whether those most able to solve the issue are doing so.

Re:U.S. Exits Paris Climate Accord by belorn on Wednesday November 04, 2020 @08:24AM (#24988763)
Which graph to look at depend on what question one has. If the question is "Who is polluting the world and need to stop" then country’s annual CO2 emissions is the single most relevant graph since that is where the pollution is right now coming from.

If one is to ask "whom's individual citizen way of living is contributing most" we would look at per capita C02. If the question is "Who is at risk of increasing their pollution" you would look at living standards and growth rates. If you ask "Who has the beast means to invest into climate change preventing technology" you would look at GDP. If you ask "where in the production chain pollution is created" then looking at trade gives that. If the question is whom is to be blamed historically for getting us into this situation then the historical global cumulative CO2 graph shows that, through I am a bit skeptical that it actually gives a correct picture since ww1 and ww2 were very central in ushering us into the age of fossil fuels.

So if China were to spin off each province as a separate country and the US were to spin of each state as a separate country with each of the new countries emitting exactly as much CO2 as it had before it was a separate country, this would be an improvement?

Re:U.S. Exits Paris Climate Accord by belorn on Thursday November 05, 2020 @03:27AM (#24996545)
Splitting of countries has as much improvement as getting higher population density. A 5 person household does not have less pollution than 4 person household just because they got one person more to share the blame. Similar two countries combined do as much pollution as if they were separated, because physics does not care about borders.

If we go by per capita, the country that contribute the most to the world pollution is a island country with 300 islands and 1700 people. At the same time there are a bunch of oil countries which list as the most green countries in the world because per capita they got close to nothing in pollution per person. If we go outside of countries, the international space station and antarctic would have insane amount of CO2 per capita since only a very small number of highly specialized people living there.

If we want to stop climate change, going to Palau and Luxembourg with remedies will have zero impact. Their numbers at top of the table is only relevant in terms of statistics.

Long term it isn't. Reducing emissions is going to cost a lot of money. There is less money available for that after economies shrink and governments print money to support their people. Covid helps emissions temporarily but harms the overall path.

Re:U.S. Exits Paris Climate Accord by pcr0 on Wednesday November 04, 2020 @09:28AM (#24989320)

This depends if we've already overshot maximum sustainable population. You can run many different machines at over 100% capacity. The issue is they break down much more quickly. Water would be a good example of a resource that has stores we can use at a speed much faster than 100% of replacement rate.
Re:U.S. Exits Paris Climate Accord by Cthulhu_ on Wednesday November 04, 2020 @08:19AM (#24988721)
The problem is that when it comes to emissions and the resulting climate change, it won't be a smooth self-correction but rather sharp and catastrophic. I believe we've already reached the point of no return and the greenhouse effect is out of control (north pole ice not recovering, permafrost melting, etc).

We'll see drastic climate change happening everywhere. It'll probably have little effect on "us" in the west; probably limited to local tragedies because of extreme weather and a price increase in food. But elsewhere it'll cause famine, mass death, and mass migration.

Sure if you zoom out enough, humanity will manage and survive just fine. But at what cost? You can try to be utilitarian about it, but you shouldn't shrug at the prospect of millions dying and getting displaced.

If the US, brimming with wealth, technologically advanced and educated can't commit to fighting climate change, what will the poorest developing countries decide? They would need to take the burden themselves and falling behind economically (something China in particular would strongly resist). A few defectors can ruin the entire plan because of economic pressure. I think we should be nearing an accord with greater control anyway -- defectors will need to suffer harsh economic sanctions greater than what they'd spend on the accord anyway.

There's no playbook here. It may look like there is, because we keep seeing the same thing happening, but it's not coordination - it's the outcome of everyone caring primarily about their own personal interests over those of everyone else. We've built an economy and a culture that demands this kind of selfishness.

COVID-19 gives solid evidence that there is no playbook involved: in terms of political and business processes, the pandemic happened in a flash. And yet every country mismanaged the reaction in roughly the same way, for roughly the same reason. This wasn't coordinated, it's the default way we fail to solve global problems.

Re:U.S. Exits Paris Climate Accord by tootie on Wednesday November 04, 2020 @11:56AM (#24990737)
I think COVID is different. There have been coordinate disinformation campaigns emanating from vested parties in the past. Tobacco and fossil fuel companies actively invest in tamping down regulation and sponsoring fake science to support their goals. There is no pro-COVID lobby in any corner of the world who wants people to die to protect their profits. Trump has made some ham-fisted attempts to pretend one exists, but in general companies big and small are treating it as very real and very dangerous to their bottom lines. Small businesses and brick and mortars are pushing to relax restrictions with the express intent of trading health for wealth. I see a really disturbing trend among American Conservatives to just decide there's nothing to be done about the pandemic and whoever dies, dies.

If anything, I think the US election has emphasized how the idea that humans can come together, globally, to solve a problem that will require worldwide shared sacrifice for benefits that are largely at least one lifetime in the future is a pipe dream. Humans (and in fairness, most creatures) are fundamentally too selfish as a species to implement this kind of collective action.

Unstoppable severe climate change is coming, if not already here. Emissions continue to go up and up and up every year, the best you get is a slight pause in a year, while we need emissions to go to zero, fast. At this point the only slight hope is geoengineering, and even then I wouldn't bet on it.

It's not "half the country". In a recent Fox news (yes, those Fox news...) poll, they found that 72% of people were either "very concerned" or "somewhat concerned" about climate change.

What is true that none of the presidential candidates is taking the crisis seriously: Trump denies it, Biden pays a bit of lip service to it but has done very little about it with Obama, and will probably not do much about it if elected.

Noting down your concern on a poll isn't the same as taking action - even the least action, voting for someone who is not a climate change denier, was beyond half the country. And if this sort of political action is what 73% produces? Then that figure isn't worth the poll paper it's printed on.

Exactly. The poll does not dictate any action - you might as well ask people if they like puppies. Sure, most people like having an environment, but they also like sitting in an air-conditioned SUV on their trip to Wal-Mart to buy a gallon of milk. Polls like this are how you get people who are absolutely in favor of better public education, but every bond measure for the last 8 years has failed. They're useless as a policy dictating measure.

Saying they take it seriously and then putting parochial concerns ahead of it at the polls every single time. And there's a vast gulf between Obama/Biden not doing enough while Trump and the GOP are running us backwards as fast as they can. Just look at the last two administrations positions on vehicle mileage standards. Obama pushed for a huge increase and got car manufactured onboard pretty enthusiastically. Trump just undid it completely and the auto companies are actually upset. That's just unconscionable.

USA per capita CO2 emissions are large, but at least they have been coming down moderately fast. From 2007 to 2017, USA reduced emissions by 20%, whereas if we take Germany as an example of a country with strong "green" element in politics, Germany reduced by 8%.

Apply linear extrapolation, and USA would go below Germany in 20 years. Extrapolating with exponential decay, in 40 years.

Isn't it bunk to apply extrapolation to two countries that start from a different per capita base?

Germany is significantly lower in per capita emissions so their reduction is (I'm assuming) a lot harder to achieve. It's like comparing fat loss between someone who starts overweight vs someone who is starting neutral bmi.

https://ourworldindata.org/co2/country/united-states?country... and add Germany.

Happy to hear why I'm wrong, I'm certainly not an expert in stats or emissions.

I think arguing percentages is misleading and is missing the point of the total environmental impact.

Using the same data source you can truly see how much of an outlier the US carbon footprint is:

https://ourworldindata.org/co2/country/united-states?country...

Basically the large majority of countries sit below the 10 tonne per capita cut-off, with the outliers of US, Canada, Saudi Arabia, Qatar, and Luxembourg above the 15 tonne cut-off (with Qatar being basically off the charts). I am not sure if it is just consumer behaviour differences or energy source differences and I am sure there will be multiple factors depending on the country and regions but these outlier countries are effectively emitting anywhere between 50% to 300% more emissions than any other population on Earth.

The main issue here is population size:

Luxembourg : 600k

Qatar: 2.897M

Saudi Arabia: 34.997M

Canada: 37.885M

US: 331.669M

If you stop thinking per capita and actually take into account total population, you quickly realize that all other nations on Earth are dependent on US market carbon correction in order to avoid environmental collapse. Far more than any other foreign policy ineptitude from the current adminsistration it's the environmental inaction and downright resistance of US lobby driven policy that scares everyone else around the world.

We are still on track for an inevitable major environmental collapse but it could still be vastly mitigated, if US politicians and citizens would get with the program.

Well, after the disaster at Fukushima, we started phasing out nuclear power. It was replaced by renewables. (This was super-stupid since we have a stable government, no enemies close by and basically no natural disasters [0] that would threaten our power plants.) We should have shut down coal plants instead but dwelling on what we should have done does not help. The bright side of this is that our emissions are decreasing despite still running coal plants. Once we shut these down, they will drop even more and this hopefully as early as possible. I hope it is going happen because of economic reasons, i.e. when coal becomes too expensive compared to other sources of energy because that would mean it would already happen before the scheduled phase-out.

[0] If you are from elsewhere in the world, it might be hard to imagine how few threats of natural disasters we have in central Europe: there are basically no earthquakes, no tsunamis, no bush fires, no (real) hurricans (we call them 'storms'), no real tornadoes (it is such a rare thing that it usually makes it to national news if there is one), no (terrible) floods (well, every few decades there is a large flood somewhere here but that's it).

Maybe it's a cost issue? Manufacturers depend heavily on low/stable energy prices, and I know that Germany exports a lot of manufactured goods and is trade-positive.

In a global economy, per-country per-capita emissions mean little, as my consumption largely "counts" against another country that produces the goods I use.

Germany has a much larger per-capita manufacturing and export sectors of their economy, I would expect their emissions to slow more slowly.

Energy & emissions are complex to account for. I don’t know too much about the US but in France we had quite good results in term of reductions.

But where do they come from? From the optimisation of our energy consumption? Or from the relocation of some of our companies abroad?

Re:U.S. Exits Paris Climate Accord by macspoofing on Wednesday November 04, 2020 @08:42AM (#24988924)
>France we had quite good results in term of reductions.

France has the benefit of large-scale nuclear power. Any given day, my home province of Ontario, is at around 85%-95% fossil-fuel-free emissions because of nuclear and hydro [1]. If instead we decided to go with solar and wind, then we'd be waiting until 2060 to cut CO2 emissions and burning much more natural gas until then ... just like Germany.

Which is primarily due to Obama era regulations that Trump has done everything he can to roll back. Had the price of gas not skyrocketed and the mortgage crisis not hit, we would've had almost no improvements from 2000-2008.

If you look at the data available from 2016-2018 we went BACKWARDS. You can't extrapolate the data from Obama's regulations that have rolled back and say: look it'll take care of itself.

Emissions have gone down because of the fracking boom. Coal power plants are being replaced with natural gas which releases half as much carbon dioxide.

Re:U.S. Exits Paris Climate Accord by tw04 on Wednesday November 04, 2020 @09:07AM (#24989156)
The fracking boom has released massive amounts of methane into the atmosphere so we basically went from something we actively track (coal emissions) to something we don't track and thus aren't regulating or controlling (methane leaking from fracking wells). This is a net negative for planet earth...

That didn't reduce emissions and may have actually increased them.

Re:U.S. Exits Paris Climate Accord by pg_bot on Wednesday November 04, 2020 @10:13AM (#24989701)
We do track methane in the atmosphere, that is NOAA's job. Methane in the atmosphere tripled from preindustrial times to 1995 and has started to level off since then. It doesn't look like fracking has lead to a dramatic increase in the release of methane in the atmosphere.

Re:U.S. Exits Paris Climate Accord by tw04 on Wednesday November 04, 2020 @11:37AM (#24990545)
Leveled off? It's at record highs and has continued to increase every single year, it hasn't leveled off at all: https://essd.copernicus.org/articles/12/1561/2020/

The NOAA tracking global methane has literally nothing to do with tracking methane output from individual wells - which again, we don't do. Moving the goal posts doesn't make you right. We DO actively track emissions from coal fired plants. We DO know that fracking has absolutely increased methane emissions:

This is part of the fallacy in this mess that climate change has become.

If the US evaporated from the planet, nothing would change. In fact, atmospheric CO2 levels would continue to rise.

Humanity cannot solve this problem by subtraction.

If ALL of humanity left the planet, it would take 100,000 years for a 100 ppm drop in CO2.

That means we can’t solve it by eliminating fossil fuels, cars, trucks, planes, etc. We can’t solve it with solar panels. And we sure as heck know the Paris accord can’t solve it either.

It is astounding to me to see see how we continue to talk about this problem from the perspective of a premise that is completely false.

> Obama didn’t start any wars

Obama:

* Started a military campaign in Syria.

* Supported diplomatically and militarily, and armed, Saudi Arabia in its genocidal war on Yemen.

* Supported diplomatically and militarily, and armed, Saudi Arabia in its occupation of Bahrain.

* Supported diplomatically and militarily, and armed, Israel in three military campaigns in Gaza.

* Started military intervention in Somalia.

* Started involvement in hostilities in Uganda.

Now, you could argue that only two or three of these count as "starting a war", but still.

> spent 8 years trying to close Pandora’s box?

More like 8 years keeping them open, or prying them open (e.g. vis-a-vis China).

But there's one notable exception: Iran. Even though he bears responsibility for illegal and unjustified sanctions, the JCPOA agreement was a tolerable compromise all around.

Re:U.S. Exits Paris Climate Accord by Cthulhu_ on Wednesday November 04, 2020 @08:30AM (#24988802)
The Syrian civil war (if that's what you're referring to) is a result of the Arab Spring that started in 2010 in reaction to low standards of living in Tunisia, which spread to amongst others Syria.

That's the wiki summary anyway, which doesn't directly implicate the US or any particular president.

That said, general unrest in the middle-east can be attributed to meddling from the US that has been going on for decades, from the founding of the State of Israel in 1948, the US funding the Afghans during the Soviet/Afghan war, to the first and second gulf war, the Saudis, etc.

While I don't like Obama's policy when it came to the conflicts down there, he inherited it from decades of policy.

US entrepreneurism kickstarted the electric vehicle transition (thx Elon1). Batteries prices are falling. PV is already incredibly cheap and getting cheaper. Coal is becoming increasingly uncompetitive. Nuclear is making a comeback, also thanks to US entrepreneurs.

Science, Capitalism and entrepreneurship will be the unstoppable force that will solve our energy crisis, if western governments let them.

Africa, India and China will be the biggest factors going forward.

UPDATE: To be clear, I'm not arguing for laissez-faire capitalism. Government incentives are required to develop markets, as Germany did with PV, and US does with EV. My point is that the US being part of the Climate Accord or not won't matter much, the move away from coal and ICE cars is inevitable due to already existing market forces. A bigger lever would be to de-regulate nuclear where it makes sense, as that is where the biggest cost lie.

Yes, everybody knows that EVs received precisely zero government subsidy in terms of R&D, business loans, and consumer rebates. That free market did it all by itself. And we've got what... 1% of the cars on the road running on electric?

Capitalism and enterpreneurship is how we got here in the first place. Elon and renewables are only becoming a thing because of economic incentives from governments - positive incentives in the form of subsidies on e.g. new EVs, solar panels, etc, and negative incentives in the form of carbon taxes.

Take those away and the "green" companies would have NO incentive to push their work. They'd be working with people wanting to do better first and foremost, and then they would - ironically - be competing with petrol and energy companies, who also have "green" all over their marketing.

Renewables and EVs could not compete without government incentives.

Re:U.S. Exits Paris Climate Accord by Veluga on Wednesday November 04, 2020 @08:31AM (#24988813)
I'd actually argue that the lack of a carbon tax - not its existence - is an incentive, since you're not charging for the negative externality of trashing the atmosphere.
Re:U.S. Exits Paris Climate Accord by pferde on Wednesday November 04, 2020 @08:46AM (#24988956)
Isn't that exactly what government incentives are for? Subsidize the thing you want to see succeed, until it no longer needs subsidizing.

Of course, that is the ideal success scenario, in the failure scenario, you subsidize the thing until it fails, or until you can no longer afford to subsidize it.

EDIT: grammar

Re:U.S. Exits Paris Climate Accord by UncleMeat on Wednesday November 04, 2020 @08:52AM (#24989022)
Of course. The point is that it is ridiculous to use Tesla as evidence that the free market will solve our problems when

1. Tesla's impact on global emissions is minimal.

2. Government intervention in EVs has been there from the start.

The charitable conclusion is that governments and markets can work together. The pessimistic conclusion is that markets are only capable of putting lipstick on pigs.
