It feels like an iceberg has been slowly turning over for the past 10 years, and is now flipping quickly. Economic growth is now more correlated with carbon re

  Meh when I see that we are barely able to stop the growth of fossile fuel usage ( https://en.m.wikipedia.org/wiki/World_energy_supply_and_consumption#/media/File%3AGlobal_Energy_Consumption.svg https://en.m.wikipedia.org/wiki/World_energy_supply_and_cons... ), I'm not sure why peoples are so optimistic. And it's not like Enr and other suggestion you propose will not need insane amount of ressource extraction. Heat pump usually need a well insulated home, just isolating all the needed house in the next 25 years is probably a challenge itself between cost and having enough workers. And it's not like there was an article last week on electrician shortage ...

    I guess when I look at that chart I’m actually optimistic: - coal and oil not really growing (but there is Covid at one end and no Ukraine war effects). This is especially noteworthy for coal because china continues to increase coal power generation so the only way for it to be flat is many others decreasing - the ‘other’ section growing at 16% per yer (doubling in less than 5 years) is basically renewables I am sad that fossil fuels continue being burned more and I’m sad nuclear isn’t growing but the growth in renewables is encouraging. A thing people often say when looking at per-country data is something like ‘emissions in developed countries are only decreasing because they are offloading polluting industry to developing nations which you can see are burning more’ but this doesn’t appear to be true. Studies that try to measure trade-adjusted emissions find that they aren’t massively different from the raw amounts and that the difference has stayed pretty steady for a while even as developed countries’ emissions have fallen despite growing economies.

      I think you are being optimistic because you are neglecting the urgency of this issue. We have maybe 10 years left to get to 0 emissions. We are not even decreasing. If this graph were something happening in the 80s, I would be ecstatic (well, if I had been born and had known about global warming). Right now, it's far too little far too late. This is not a time for finding a new way of abundance, it is a time for accepting that we have been growing our economy on burrowed time, and we have to significantly shrink the global economy ourselves, or the planet will do it for our children or grandchildren 20-50 years from now.

        I don’t think the crises or emergency phrasing is particularly accurate. We have already locked in a great deal of climate change over the coming decades and urgent actions now won’t change that. I don’t think ‘emergency’ should apply to situations where things get worse over the next 30 years but actions today may cause them to be less terrible in 80 years. The narrative about shrinking economies doesn’t make sense to me because for lots of countries like the US, they emitted more when their economies were smaller. We don’t want to go back to that. I think pushing to reduce emissions by shrinking economies is unconscionable as it effectively corresponds to reducing standards of living across the world and particularly harms the poorest countries. I also dislike it because it is obviously politically unpalatable and so the people who favour it either long for some kind of authoritarian to impose it[1] or get to smugly say they were right while their desired plan doesn’t get implemented. I would much rather governments were pushed towards policies that would be desirable to people while also reducing emissions. [1] I also note that the biggest authoritarian country is burning more and more coal with increasing emissions while the biggest non-authoritarian countries have falling emissions and growing economies.

  > Environmental groups and common knowledge haven't caught up yet, but the fastest route to a low carbon future is a lot of factories producing ev cars, appliances, and batteries. Not sure where you are getting this, but sounds like you just have an axe to grid. Environmental groups have been pushing for decarbonization and accelerating the shift toward a renewable grid for forever and a day. They were the ones who educated the public about the imminence and perils of climate change, drove legislation in places like California that created the environment where EVs became popular. It wasn't Chevron, or Ford, or even Tesla that did that. The groups that weren't onboard until now are mainstream capitalists and consumers. > For 80% of the things we need to do, it's just people going to home depot. As someone who has recently built an entire electrified high-performance house that consumes a fraction of the typical house's energy, I could easily buy into this, but it is flat out wrong. What I accomplished was building a cheap-to-operate, comfortable, and healthy house for my family. It negligibly reduced the CO2 emitted on the grid, and significantly reduced the amount emitted on my behalf (by eliminating my direct natural gas usage) but I'm still reliant on a grid that is 50% fossil fuel powered. What I did is not particularly easy to replicate either, unless you are doing a full gut remodel or new construction - so not something that trips to home depot can accomplish. The bottom line is that it's not a scalable near term solution for our climate issues. Instead, a huge amount of what has to happen in the near term is development and deployment of firm grid scale renewables and the systems to coordinate and transmit energy between those and flexible sources of demand.

    It's a little bit more complicated than that. They've held onto their legacy concerns about certain non-carbon power sources for other reasons, and many environmental groups seem convinced that there is no future where the planet is safe and our current economic system stays in place. I could even be convinced of the latter, but I know enough to know that both of these policies are political poison pills in effect. Plenty of environmental groups have done plenty of harm to the cause, largely from not accepting half a loaf.

  > There are many zombie environmental groups that will continue to fight against anything humans try to change about the built environment, but over time the astonishingly good economics will move them to the side. I think environmental groups are just the tip of the iceberg that gets blamed for things because they're visible. They just don't have that much political clout (aside from the very large "environmental group" that's people who are concerned about climate change -- which may be a majority of all living humans at this point). As an example, consider strict environmental regulations on oil refineries. It seems like those must be pushed by environmental groups, right? But it can also be a case of regulatory capture by the incumbent refineries. The regulations don't apply to them because they were grandfathered in, but the regulations are their moat protecting them from any upstart competitors. Or consider fuel economy standards. Those must be pushed by environmentalists, right? But then why do light pickup trucks have very strict fuel economy standards, and larger trucks have looser, easier-to-meet standards to the point where it's hard to actually make a light truck that conforms to the standards and isn't really slow and underpowered. It's almost like the incumbent automakers have been successful at lobbying for regulations that protect the lucrative market for oversized trucks by ensuring that smaller trucks are unappealing, unavailable, or too expensive. (The chicken tax is another example.)

  Maybe that's because Global Warming isn't the only environmental issue that they're concerned about? We started getting massive bio diversity reduction since the 70s and that wasn't because of AGW. Human consumption of natural resources (esp. habitat) is a huge issue for the environment and "a lot of factories producing ev cars, appliances, and batteries" will accelerate that.

    Yep this is like saddest thing that 50% of species died in last 50 years due to human activity.

  >It feels like an iceberg has been slowly turning over for the past 10 years, and is now flipping quickly. >Economic growth is now more correlated with carbon reduction than increase. Does it now make sense why so many hydrocarbon companies want to fight against climate change and push and promote some inefficient processes – like hydrogen that mostly still use hydrocarbons to power them? They know that weaning people off oil directly means a hit to their easy money streams. They don't want their hegemony to die and they are doing their very best to keep us addicted to easy and "cheap" energy. At this point in time, if you have a politician that wants to slow down decarbonisation they are either in the pocket of big oil or just stupid. The alternative, tightly coupled energy system that feeds dictators and polluters, is not something we should contribute to any longer.
