It's gonna be great, when it's warmer.

Re: Global warming has accelerated significantly
#482FWIW 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.
Otherwise it doesn't make sense to put CO2 into the air with one hand and take it out with another.

You saw our reaction to covid. Millions. It will take millions of deaths in a nuclear armed country. See 'The ministry for the future'

Wasn't a drought originally part of the cause of Syria's collapse into civil war? Climate change is already causing unrest in equitorial countries, mass migration and a corresponding rise in authoritarianism / right wing populism in Europe.
You're making the "It's snowing there can't be global warming" argument in reverse. One local drought can't be attributed to or be proof of global warming. It's like smoking causing lung cancer; (the following numbers are made up) 5 in 100 non-smokers might get lung cancer but 20 in 100 smokers do. 5 of those smokers would have gotten lung cancer anyway and 15 wouldn't have but there's no way to know which individual…
Oh no, on the contrary, I'm saying it's already started and people aren't paying attention.
Re: Global warming has accelerated significantly
#485Don't kid yourself - we closed this one with "Won't Fix" a while ago. "But what about ?" No. Full stop. We're not going to do it, and we're not even going to apologize for it either. All we can do now is prepare, not that I've seen a lot on this front either.
We'll fix it if it become cost effective. It might, but probably won't because if the scale.

What about solar shades? Seems like a relatively quick and easy way to regulate solar input. It's nice too because you can quickly remove it if necessary.
Reducing sunlight to the surface means we lose solar power effectiveness and we need to use more power for artificial lighting to grow plants.
Re: Global warming has accelerated significantly
#487What a surprise with all the wars going on, and AI depleting Earth resources, what a change from about the pandemic era when everyone was into paper straws and cups and promising to be a better person, because that is what was going to change anything.
All data centers in aggregate (AI and all other uses) use about 1.5% of electricity production, which itself is about 20% of total energy use. So when people are focusing on AI above all other energy uses, it doesn't really paint an accurate picture of what's going on.
Wasn't crypto a significant percentage as well? And that was before the AI buildout started.

> Nothing will change until developed rich countries are starting to hurt. Ironic OECD countries actually REDUCED their emissions based on a peak in 2007 and continue to do so. Not reduced as a percentage of GDP or adjusted for population growth, but reduced in absolute levels. It's all China, but I guess it's cool to blame things on developed countries. There are literally 100k deaths in Europe that can be prevented…
> Ironic OECD countries actually REDUCED their emissions based on a peak in 2007 and continue to do so Any idea what percentage of this reduction is due to offshoring manufacturing?

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…
> What happens when 1.5B come knocking because if they stay they die? Like let them build few of those sci-fi domes and let them keep buying disposable bottled oxygen? I don't get the pessimism. India makes its own rockets. Pakistan has nukes. Why are they supposed to be incapable of holding the nation together on Mars-like Earth? Tokyo is already hitting 40C/100F at >90% RH during summers. It's already mildly unsurv…
The fact people already live in some of the hottest places in the world today should speak a little to human resiliency.

We are already far past the point of mere thousands of lives. Entire cities have been wiped off the map by floods.
It will take millions, if not close to a billion lives before we get serious
