I am not advocating regulation since I don't think the government can do a great job predicting what the correct energy sources are for our economy. Instead, I advocate for a fee on fossil fuels to represent the fact that every time you buy the fuel with the intent to burn it, you are doing harm to others, and that harm is not reflected in the price you are paying. (BBS and I have discussed this in another thread; I believe this is true because most consumers don't really understand the future impacts of global warming, and don't appreciate or care about the impacts it will have on people that live far away from them. However, we never finished this conversation, I think.)

There's the demand revelation problem: what actually is the socially beneficial quantity of goods from pollution demanded.
Then there's the incentive problem: both you and I agree on a carbon tax, and let's say we rack our brains to get the best rate we could determine. What happens when we offer our plan to a few legislators? Well, they'll likely be favorable to it (because we picked environmentalist ones--since we're good at political entrepreneurship), and then they have to haggle with other legislators to pass the bill (at a committee level, then at the general assembly level).
Meanwhile, many underground deals will be made among legislators and special interest groups--while an overt exchange is made among legislators and voters (insert sentimental advertising campaigns--with the ongoing rage and stupidity of democratic interaction). After this political process (of nonsense), I'd expect to get a very fucked up version of our plan which will probably be poorly enforced or gouged to the point of ineffectiveness.
This is generally why I don't trust government to handle these issues, but utlimately, this conclusion is my opinion--informed by theory and by a smattering of empirical evidence on somewhat related issues. I'm open to refutation and discourse, but 'refutation and discourse' are not part-and-parcel of the political process. It's not about science; it's about rhetoric and generally zero-sum or negative-sum exchanges.

"2) This argument doesn't really make sense. The existing taxes weren't somehow encouraging use of fossil fuels; taxes generally serve to decrease demand, not increase it, due to the increased price.

I have many issues with this. First, you are coming with a bit of BBS on this. Some things aren't voluntary exchanges. Increasing tax only offsets the lowest consumer when the exchange is involuntary, if suitable alternatives aren't available.
The second, "they are not encouraging fossil fuels". Of course they are. The taxes are discouraging the government from taking action against their self-interest. If you want to show me graphs on the Prius, then that shows a poor understanding of fuel economy. The VW Rabbit diesel had better mpg than a Prius more than 30 years ago, far more miles per engine and doesn't require rare earths. In other words, the life cycle of the Prius sucks in comparison.
When the Nissan Leaf came out, at least in China, it was restricted to government use. When the Ford Fusion plug-in came out, it was restricted to government use. While these have the same issues as the Prius, at least they give better mpg.
For a long time, the US government has tied itself, the economy and the world to oil. With a more widely available form of energy, the US would plummet in world standing. That is, the quality of life would increase everywhere, including the US, but in comparative turns, the US would be on the same level as a third world country. The world would be more balanced and small nations and individuals would not be readily exploited.

Taxes decrease demand for everyone, it's just a larger effect on those with smaller incomes. But either way this point is not really responsive because I was just taking exception to your claim that the government uses taxes to stimulate fossil fuel emissions. The only way that could be true is if people burn more gasoline when it's more expensive (I think it's obvious why this is false).
Edit: it occurs to me that you may be arguing for the existence of a Laffer curve here. Let me know if that is what you are getting at.The second, "they are not encouraging fossil fuels". Of course they are. The taxes are discouraging the government from taking action against their self-interest.

Sure, it's true that by having high fossil fuel taxes, the government might have an interest in not diminishing the amount of fossil fuels. But nevertheless, the US has its CAFE standards, British Columbia has a $30/ton carbon tax, and 20-odd other localities have some sort of carbon pricing scheme in effect. The inevitable conclusion this leads to is that there isn't only one government perspective on this. Most governments are far too large and far too complex to speak of the "interest" of the government. Gasoline taxes for things like highway repair are obviously just being used for different ends than a straight carbon tax would be, and they might have conflicting interests, but so does many, many things the government does. (Especially when you consider the conflicts between provincial/state and federal taxes.)
Regarding your argument about the Rabbit: it's a false comparison. First, the Rabbit was popular right after the height of the oil crisis; that is, it was only high fuel prices that encouraged innovation towards efficiency. This supports the hypothesis that a carbon tax would spur us towards more fuel-efficient vehicles. Second, the Rabbit is just one car. Not everyone wants to drive a Volkswagen. What matters is when the average fuel economy goes up across the board, so that no matter what the consumer's preference is, he or she can purchase a car that they like and is also better on fuel.When the Nissan Leaf came out, at least in China, it was restricted to government use.

Yes, but now these things are available to the consumer market. The government can't, and isn't, keeping these things locked up forever.For a long time, the US government has tied itself, the economy and the world to oil.

That is, the quality of life would increase everywhere, including the US, but in comparative turns, the US would be on the same level as a third world country. The world would be more balanced and small nations and individuals would not be readily exploited.
This is a simply false analysis. For example, if the US had gone full throttle for nuclear power starting from the 1940s, we still could have had world dominance in the energy market due to our technological superiority, if we had handled it well. We just went a different route. And we can still go a different route. Our economy is so large that whatever energy markets we invest in, we'll maintain relevance. And your biofuel example proves the same point. It didn't have to be oil.
(But again, direct your arguments at me, not the government. This argument you're taking is lazy. It's saying "here are the things government wants to do." When did we stop talking about the things the citizens want to do? Why is the default argument now "that will never happen?" That's ceding away power in a way that guarantees that only government interests matter.)

Your analysis of my false analysis is false. Uranium has an inherent problems. Not widely available, poses many dangers and can be weaponized.

1) Non-unique: there's usually a conflict of interest when the government collects any tax revenue, because of the way state budgets usually work.
2) This argument doesn't really make sense. The existing taxes weren't somehow encouraging use of fossil fuels; taxes generally serve to decrease demand, not increase it, due to the increased price. So, adding another tax to further decrease demand isn't a new conflict of interest, it's just a continuation of existing policy.
3) I advocate for a carbon fee where 100% of the revenues are returned directly to the citizen. In this way, the government cannot use the funds to further its own interests.
4) Why are you talking about the government and its intentions? I am the one who wants the carbon tax, as a citizen; I am not the government, nor a representative of it.

I don't want you to pay me. You would likely come out ahead -- that is, you'd have more real income after the revenue-neutral carbon tax than before it. But the reason we have to use government here is one of incentives. If fossil fuels are cheaper than other sources of energy, people will use them. However, if there's a financial incentive to switch to renewables, that will then happen. A carbon tax would encourage this by making fossil fuels more expensive than the alternatives; if you stopped using them altogether, you'd get a free check (corresponding to your share of what everyone else is burning) until we switched off entirely. I'm not trying to take money away from the people, since I demand that it be returned.You say that many places have a carbon tax in effect, and quote at $30/tonne.

Correct. If we instituted a $300/ton tax that was off one year and on the next, it would devastate the economy.

I didn't say anything about uranium specifically. Just like the fossil fuel industry, the nuclear industry would have innovated if we had let it. (Indeed, it is innovating in places where the government is allowing it to, like China and India.)Again, back to addressing you. If you want to sell me something, then you need to offer me a benefit.

Even if you don't believe in or care about the future impacts of climate change, this tax is going to make you money. And it's going to improve the economy. What's not to like?When did "citizens" ever get to decide anything?
This is the nature of democracy. If all you do is complain, then you're going to be doing that forever.

In the second article we see that all CFC substitutes constitute a effect of 0.012 W/m^2, HFC being one of them.
https://uwaterloo.ca/news/news/global-w ... study-says
I understand that the last one has been challenged by your community.
So 100 times gives us the temperature equivalent of a global summer.
If we take the hundredfold comment to mean the total levels of HFCs in the atmosphere, which last 15 years in the atmosphere, and say that substitute CFCs are wholly HFCs, or that the 0.012 W/m^2 effect is solely derived from HFCs, then lacking a linear regression, a hundredfold would be equivalent to an effect of 1.2 W/m^2. And is equivalent to a global summer.
The two articles then seem to verify the third article, that warming was indeed caused by CFCs, whose use was decreased significantly after their ozone depletion effect was recognized. Though the article isn't specific as to the contribution of CFCs prior to 2000, it does state that the total effect from all ozone depleting substances remains at 0.32 W/m^2. Had the protocol not taken effect, the current rate would be at 0.65 W/m^2.
Given that HFC has an effect of a global summer at 1.2 W/m^2 and that all ozone depleting substances contributed 0.32W/m^2 and that they remain 15 years and longer in the atmosphere, what impact would this have on the temperature record from the seventies to now?
To me it would suggest that the initial 0.32W/m^2 would contribute to the equivalent of a quarter of a global summer, the reduction period would then maintain the contribution for 15 years and then we would see a temperature decrease following the life cycle in the atmosphere.
Does temperature data reflect this, or does it follow the steadily increasing amounts of CO2 and constantly warm each and every year?

shickingbrits wrote:I brought up CFCs because the article has a few points of merit on counteracting the cooling effects of a large deposit of CO2 in the atmosphere.
It highlights the point that CO2 has a cooling value in the upper atmosphere, which is no surprise.
But to your graph. I suppose this is the clear evidence of CO2 measured warming as promised.
Next, please explain the difference in atmospheric changes and ocean changes based what you explained above. Going from 10^21 J to10^23.5 J is such a small percent that it could be explained many ways.
shickingbrits wrote:I like the planet attempting to stay in equilibrium. Sounds cute. On the other hand, the second law doesn't like "the troposphere is warming up, that has to be balanced by a cooling off somewhere else."
Nature doesn't like thermal gradients, that's exactly what the second law says, and when thermal gradients do come about, nature reacts with something called weather. Nature likes vortexes, they are the most efficient way to disperse something widely.
This is quite clear. Clear enough to be called a law. It's the reason we know the core is molten. The reason we put on jackets, seal our houses to the extent that we still have decent air, the reason it is colder inland than near the sea, the reason our extremities stop receiving blood from the heart first. I don't bake a potato and a magical cool spots appears and is equal and opposite, i.e. a cool pocket. The heat radiates outward creating a new, higher equilibrium temperature throughout my house, my house radiates energy at a higher rate to the surrounding environment and the equilibrium reverts to the original.
So please try again on explaining the cooling effect of CO2 in the stratosphere.
CO2 reflects solar irradiation in the upper atmosphere. CO2 prevents heat from reaching the land and seas where the surface volume can hold the heat for any length of time.
No, that is far from the only explanation. It's not like CO2 is chilling all by itself. It has friends.

The atmospheric system is more complicated than just an isothermal ball of gas, as you indicate. Thermodynamic equilibrium is an important foundational aspect, but it doesn't apply to the Earth as a whole to mean that the system reaches a single equilibrium temperature. This is true for many reasons. Even without complicated things like weather and convection, there would still be gravity. Plus, the Earth is not a closed system. The Sun can radiate energy into it, and it can radiate energy back out.
Instead, typically what does apply is called local thermodynamic equilbrium. Any given patch of the atmosphere will attempt to come into a thermodynamic equilibrium state, and that's generally assumed so that we can even speak of the temperature at a given point in the atmosphere.
But all of this is a red herring, because when I said "equilibrium" I did not mean thermodynamic equilibrium. I meant a system that is stable, i.e. not changing in time. That's generally what physicists mean when they are referring to the equilibrium of an atmosphere; but, I can understand why you were confused. One can write down equations for what an equilibrium atmosphere looks like, and it's generally some combination of temperature, pressure and density that is static with time. Notably, it won't be one that has only a single temperature. Instead, if everything is nice and static with time, then the amount of energy in the system won't be changing with time. This is the key assumption of an atmosphere in equilibrium with the incoming solar radiation: it has to radiate out to space as much heat as it is getting pumped into it. If that is not the case, then the energy is building up somewhere. And at that point, the temperature is going to continue to rise, until it's pumping out enough energy to balance the incoming energy.
All of this is to say that I can't really answer the question you're asking, because you're making some incorrect assumptions about the way the atmosphere works.So please try again on explaining the cooling effect of CO2 in the stratosphere.
I agree that my description was a hack, and may have been misleading. Physicists use energy conservation as an intuitive guide to what must happen, but it's not always obvious how the physics will play out to guarantee it.
Let's describe it in different terms. Suppose you increase the concentration of carbon dioxide uniformly throughout the atmosphere. The troposphere will warm for the reasons already discussed: the air is thick enough there that radiation from the ground is trapped by the carbon dioxide, and more CO2 means more trapped heat. So the troposphere warms. However, the stratosphere is very thin. So, the carbon dioxide will have the effect of radiating away some heat, but it's not absorbing enough from below to compensate, so energy is lost and it must cool. We can make this even simpler -- assume that the stratosphere doesn't absorb any energy at all. This is not a terrible approximation because of how thin it is. Then, adding CO2 to the atmosphere will always tend to decrease the temperature. CO2 is good at emitting energy, and so it will absorb energy from the dominant constituents (nitrogen, oxygen) and emit it to the infrared, losing it permanently. This will lead to a new equilbrium at a lower temperature. This is slightly complicated, so we can go through it in more detail if you like.CO2 reflects solar irradiation in the upper atmosphere. CO2 prevents heat from reaching the land and seas where the surface volume can hold the heat for any length of time.
Reflection is not an important process here, especially in the stratosphere. The atmosphere is so thin that you can basically neglect direct reflection of sunlight in the upper atmosphere. Similarly, for longwave radiation the dominant contributor to what keeps the energy in is not scattering/reflection, but absorption. Going any further would involve a discussion of quantum mechanics. Just accept it as given that in this part of the spectrum, CO2 is really efficient at absorbing light, but the amount scattered would be very much less. In the visible (shortwave) part, neither process is important. So basically, this hypothesis doesn't hold water.No, that is far from the only explanation. It's not like CO2 is chilling all by itself. It has friends.
You need to pay closer attention to the chart. The decrease in radiation is not happening simultaneously at all wavelengths. Instead, it is happening at precisely the same wavelengths where we know that carbon dioxide and methane (and ozone, etc.) have absorption bands. In order for any other hypothesis to explain the decreased amount of outgoing radiation, it would need to explain how it could generate decreases at precisely the same wavelengths that mimic carbon dioxide and methane, and not any others, without actually involving carbon dioxide and methane. Needless to say, we can discard that hypothesis.
But all of this is a red herring, because when I said "equilibrium" I did not mean thermodynamic equilibrium. I meant a system that is stable, i.e. not changing in time.
