fta: "Our best hope in the face of inevitable rises in heat? Cooperation. “We’ve built forecasting systems that will warn us when disasters are incoming by working together at enormous scale. We must continue to do the same.” This sentence basically says "we don't need to make less disasters, just better handle them".

Or we can't make less disasters so we better handle them.

The thing to think about, is how poorly developed, rural places, without ACs or stable grids , are much more likely to experience heat waves with universally fatal wet-bulb temperatures. Places like parts of India or Bangladesh with high population densities, too. Further more, I think, we also need to consider how non-survivable conditions to humans, may play out for other animals we depend on. The cows, chicken, sh…

As opposed to our current icehouse phase, plants have thrived during intense greenhouse periods of global climate. "Earth has been in a greenhouse state for about 85% of its history... Earth is now in an icehouse state, and ice sheets are present in both poles simultaneously." https://en.m.wikipedia.org/wiki/Greenhouse_and_icehouse_Eart...

Great, but I don't really care about plants. Did humans thrive too?

This is why I think we should be seriously considering atmospheric aerosol injection already. Not sure why there aren't more large government funded studies of this.

"Sir you should stop drinking and smoking or your liver and lungs will die" "It's ok I'll get a liver and lungs transplant :)" We'll really do everything before we consider stopping the root cause lol. And heat isn't even the only issue we're facing

I think it's more like, you have a viral infection and it's causing a high fever, and that fever is about to kill you. Should the doctor try and bring the fever down or go and research a cure for the virus? Sometimes you have to treat the immediate symptoms first because curing the underlying condition will take too long.

Sleep underground during the day, crawl out at sunset and work through the night

This assumes we don't need any ecosystem like farming etc in that area.

And it doesn't work longer-term, because "cool ground sandwiched between hot lithosphere and hot atmosphere" ain't gonna remain cool.

Frankly it's not one or the other, it's both at the same time as much as possible because we're extremely late to this party.

How do we control that? The medical industry has the challenge of having to intervene to a late stage illness with multiple interventions that must be titrated appropriately. They have the benefit of a much smaller scale though, and they've researched and learned from past cases. How do we intervene in the entire planet with multiple modes of change without making things worse? I reach for the solution of removing im…

Well there are risks of course, and it will most likely make things slightly worse for a while with less solar power and smaller crop yields with less sunlight, but there's really no other way to fix this mess.

The simple fact is that removing all of our impact in terms of just stopping release of C02 and methane (as impossible that would be to achieve with our entire society built on energy dense fuels and entrenched interest in keeping it that way) would not be enough at this point. We are cumulatively increasing atmospheric energy retention while also reducing reflectivity and both of those are more or less permanent for a while. Safe or not we'll need to add more reflectivity to give the ecosystem time to recover. Carbon capture won't help in the short term either, the oceans have absorbed too much already and will start releasing it if atmospheric ppm falls below the absorbed density.

To continue your medical analogy, you've got a smoker with lung cancer and having him quit smoking and moving to the country isn't going to be enough to save him, the damage is done. He needs some goddamn chemotherapy or he'll end up like Steve Jobs.

What would take decades? Nearly every business switched to work from home in a matter of weeks because the fear of a pandemic gripped most politicians. Why couldn't we do that now to reduce our use of oil? The fact is we have a massive amount of waste in the system that we just aren't willing to give up. How much could be saved if we didn't expect that every McDonalds in the country could provide the exact same menu…

I don't mean to be rude, but are you aware that CO2 emissions continue to _increase_ year after year? That despite the world's apparent effort, we have actually made _no_ progress in reducing our greenhouse gas emissions globally? Given this reality, how do you expect to achieve your goals in a reasonable time-frame?

Our use of oil has also continued. We like to collectively talk about reduction but its incremental at best, and not enough to keep up with increased consumption elsewhere or actually meaningfully reduce anything.

> Given this reality, how do you expect to achieve your goals in a reasonable time-frame?

In the context of this thread, there's a bit of a false dichotomy here. You're asking why I should expect that people can choose to make a meaningful reduction in consumption as an alternative to filling the atmosphere with theoretical solutions that have never been tested before and who's impacts are unknown.

Are you proposing that because people don't care enough to reduce consumption we should just let the authorities in charge spray a bunch of chemicals into the atmosphere and hope it works?

At that humidity level you can't cool by sweating. We've had days like that in southern Sweden, near the coast with very high humidity. I'm starting to go crazy over us not having ACs, and windows that are really hard to get working well with a portable ac. Retirement homes celebrate getting ice cream machines, but still lack AC and the deaths during summer are significantly higher =/

Europe in general needs to get with the program. The States have AC'd everything - busses, elevators, train stations, etc. Ice coffee in Europe is not a thing! Ask for it and you will be looked at funny. And even the "cold" drinks from the fridge in a store are just below room temperature. I don't get it.

Why do you say things which are simply untrue? Doesn't sound like you ever visited here.

Extreme cold kills far more. https://www.forbes.com/sites/joshuacohen/2023/07/19/excessiv...

You know what's wild? Global Warming will create more extreme cold events in places that don't have them! Why? Because global warming is causing the jet streams to weaken and cold air in the arctic escapes more to the south. Isn't that interesting?

Fun fact I remember reading in some studies: increased heat increases tendency for violence. Ah, not the ones I had in mind, but these will do: https://www.washingtonpost.com/business/2019/07/16/two-new-s... https://www2.psych.ubc.ca/~schaller/308Readings/Anderson2001...

Entirely obvious for anyone living in a city that both heat and the full moon have a tangible effect on that.

Its hot during the day, so people come out at night and can see if there's a full moon. Considering that it's still night, people may be drinking and can be generally up to no good.

> Ice coffee in Europe is not a thing! What?! How long haven't you been here?? I can't remember not having wide varieties of iced coffee, frapuccinos etc. in basically any cafe I've been to in at least 10 years... Europe is not a single place though, so perhaps you mean a certain part of Europe (I am familiar with France, Italy, Spain, Sweden, Austria, Poland, Belarus and a few more surrounding these countries)!?

I ordered an ice coffee in Lviv and I was told - "this is not a thing". Lviv has hardcore coffee culture, too. After that I did not dare order it in other countries. So, are we talking a nice pint of ICED coffee, with ice cubes jiggling in it?

First of all bunch of countries in Europe straight up have Starbucks where Americans can order their usual "americano", "sugar with caffeine" and "sugar with caffeine on ice" drinks that you call coffee. Second of all you definitely can get iced coffee in Ukraine (including Lviv), I guess the place you went to just didn't serve it.
