FWIW my personal assessment is that this acceleration is both real and largely out of our control. Models in the past did not attempt to account for non-anthropogenic carbon emissions, but as we experience further warming, most especially in the Arctic, feedback loops and tipping points mean that this (carbon emissions caused by “natural” processes) are becoming more evident. This is especially sensitive because a la…

> direct air capture is the primary escape hatch We MUST MUST MUST stop burning things. Stop it. - We are still mining and burning coal. This is incomprehensible. US, AU, etc Eg: https://www.nacoal.com/our-operations - We are still subsidizing oil to around $1T/year, not counting oil wars. Yes it will take some grid and storage upgrades (US) and continue to embrace renewables. It would be cheaper than the oil subsidy…

This is why it's clear we will never do anything to slow the progression of climate change.

By far the most effective an immediate solution to limiting the damage of climate change is to simply to keep fossil fuels in the ground.

People talk about the economic pain of doing this, but that economic pain is nothing compared to the impact of unmitigated climate change.

Even though this would be painful, it is also by far the easiest and fastest to implement solution. It would take fantastically more time and resources to scale up direct air capture (even if it existed in a scalable format today) to come anywhere near addressing this problem.

> Yes it will take some grid and storage upgrades (US) and continue to embrace renewables

This is not exactly true, we would have to experience global economic collapse in order to reduce our fossil fuel use. 80% of energy is not spent on electricity globally and this is non-electricity usage is where most of the fossil fuels are consumed and this drives most of the global economy. There's a good reason there are multiple wars being fought over for oil.

This ship has sailed, warming is irreversible. Developing nations mainly in Asia (China, India etc) are, well, developing and burn like there is no tomorrow. But they are not to blame. It is their turn to live nicely, like the US and Europe did for decades. Nobody can remove this right from them.

this strangely self-hating and suicidal message has been spread for decades now, this falls along the same kinds of thinking as blood grudges and blood wars.

we don't need to adopt this form of thinking at all, no one is owed anything.

> I’m of the opinion that direct air capture is the primary escape hatch we have for not hitting 3 or even 4C warming in the next 100-200 years Why is it always never 'burn less fossil fuels'. Anything but the oil company bottom line huh?

We could cease burning all fossil fuels tomorrow and we'd still have to resort to geoengineering. Read the IPCC projections. All of the ones that keep us below 3c require 'negative emissions'. That's code for DAC, a technology that we've only ever deployed to small pilot projects, deployed more widely, more quickly, than we've deployed any technology ever.

TLDR: We're gonna have to use sulfate injection until we can transition our economy

It's my understanding that if you look at a large enough historical time window, although warming has accelerated recently (and we are in part to blame); the Earth is still relatively cool compared to historical averages.

Milankovitch cycles? What time frame? Did humans live in the same areas during that time? At -4C cooler new york city was under 2000 feet of ice. +4C would be devastating for most of humanity.

I am not sure how not directly linked to global warming. I am currently on the phone but I remember a study that mentioned that Pakistan, India, and Bangladesh would see a deadly heat (wet bulb temperatures) from basically 0 as it is right now to 30 days/year by 2050 or 2060. I can't remember right now. If that is not linkable to global warming I am not sure what is. And that is a huge event. In Europe we are struggl…

Chapter 1 of "The Ministry of the Future" describes a fictional wet bulb event. It's grisly and horrific and I highly recommend you read this chapter, it changed my view on climate change. https://books.rockslide.ca/read/780/epub#epubcfi(/6/14!/4/2/...

Thank you. I will

That is completely wrong. First, the West and particularly the US are still well ahead of China regarding both historical total emissions and per-capita annual emissions. And regardless of what China does in the future we still need to get our acts together domestically. Also, China is aggressively pushing low-carbon energy sources on all fronts. Where they are now is not necessarily an indication of where they will…

If the United States stopped polluting 100%, global pollution would decrease by only about 10%. Probably even less, because much of that pollution would simply be exported through outsourcing. So what happens next?

Please remember that we are not talking about stopping climate-related policies. The point here is climate-related science. And even if you are an arch-conservative and you assume (despite all observations) that you can do fuck all about it, knowing how things are going to be is very useful if you intend to survive, never mind thrive.

Yes. The obsession with demonizing AI/data centre loads seems to be a deliberate distraction from the much, much larger carbon loads of the economy at large relative to which IT power consumption is a tiny proportion.

Animal agriculture is around 15% of global emissions, and AI is probably .1% to .5%, but sure, stop using LLMs. That will solve the problem.

Indeed lets tear down forests to build soya fields for all that fake meat tofu.

AI is nothing compared to automobiles and heating, construction and shipping. It uses a bunch of energy, but not so much compared to moving yourself around in a car of plane.

Which in turn are also relatively small compared to the damages of cattle and fishing. Seriously adapting our diets around being more sustainable. I'm not advocating for veganism or such, but at least to understand that eating a burger pollutes as much as driving a large vehicle for 50 miles and that maybe we can substitute that with poultry or eggs or cheese many times.

What about putting trees down for soya fields?

Developed rich countries are hurting. See the wildfires across North America, massive amounts of flooding across Europe, etc. Nothing will change until many of the global electorate stop burying their heads in the sand. These people don't change their minds until things affect them specifically. Then they change their mind, and all their former fellows tell them they're brainwashed. This doesn't change until nearly e…

Politicians, at least freely elected, are a symptom of given population at given time. Don't blame trump for trump, he made it painfully obvious to whole world who he is and who he certainly is not, sort of kudos to him for being consistent. Blame fully the people who saw all this and voted for him twice . At least if you care about root of the problems and not just venting off. I am not offering a solution to educat…
