Cause he’s rich and can afford it regardless what happens. Why would you pay for ice at a convenience store when you could make it yourself at home.

I dont think rich people like to lose money.

Would you pay for ice when you know it would already melt when you get it?

I have the feeling that many people (especially politicians) think that global warming is a linear process. It's not. It might even be exponential since some sources for climate-warming are affected by warmer climate. For example, melting ice that reflects sunlight back to space [ https://arcticwwf.org/places/last-ice-area/ ]. I'm thinking about choosing a new place to live right now.

Where ought one move to optimize for climate change?

The great lakes. Fresh water is gold

> Any control theory guys out there with suggestions?

Nothing small and cheap. We've been applying a massive forcing effect by adding billions of tons of CO2 per year to the atmosphere over decades. It's going to require a commensurate amount of effort, at the very least, to swing the needle back in the other direction.

Our best bet might be something crazy like using nukes to set off volcanoes to generate an ongoing low level 'nuclear winter' type effect. We'd have to be careful to pick the right volcanoes, though, to minimize the CO2 emitted by said volcanoes.

Every year, it seems like we get closer and closer to the end. One day, temperatures will be so hot, and they will not go down. They will only continue to rise, people being kept alive by AC. Then the power grids will fail, and AC won't work, and people will just pass out from heat strokes and die off. And the world will be left with only the few who can withstand the increasing temperatures. And then the temperature…

I don't know if this comment is serious or not, but if so, it is hyperbolic nonsense. Not to say there's no warming, obviously there is, or to say it won't have detrimental effects, but it's people saying things like this that give deniers ammo to call it a doomsday cult. If you truly believe what you've just said, you need to take a step out of your own head and unbiasedly self reflect and examine the merit of your…

Why would it be hyperbolic? What exactly do you think happens when temperatures keep rising to unbearable levels? Keep cranking up the AC? What about the crops that feed the animals we eat to survive? What about the dwindling oceans we farm sea food from?

I'd like to remind the HN community, some of whom are rather quick to defend the corporate matrix, that fossil fuel companies saw this coming in the 70s and covered it up. And they had broad, deep-pocketed support. Government subsidized them, and protected them after their oil spills. Media ran Exxon and Chevron's greenwashing ads, Police beat up protesters, going so far as to infiltrate their groups, seduce their le…

Anyone who drove a car or took a flight or bought things they didn’t need contributed too. Don’t try and weasel out of it.

Don't do that man.

The oceans are growing acidic, countless species are being lost forever. We could literally all die because of this.

Blaming me for my commercial air travel while Chevron can imprison a lawyer for fighting against them is beyond fallacy, and well past what I can describe in polite terms.

Do you have family in the oil biz or something? Why would you do this?

Sulfur dioxide aerosol injection in the stratosphere until carbon capture and decarbonization can catch up. We desperately need an energy inexpensive way to sequester atmospheric carbon underground in stable (mineral) form. Hopefully we’ll see progress from Climeworks or similar concerns in this space. https://iopscience.iop.org/article/10.1088/1748-9326/aae98d/...

I read something recently about seeding beaches with crushed limestone which accelerates CO2 absorption through weathering or something.

We should start by working to keep the ocean clean, then worry about the temperature of the polluted water. Why is there more interest in controlling the temperature vs the pollution itself? consumerism needs to change for temperature to change

Climate change may very well be an extinction level event. Plastic in the ocean is not.

we can't accurately predict tomorrows weather or even trajectories of hurricanes, but lets go with this idea that the modeled weather forecast that's a decade out is realistic

What will you do to drive change?

If I could use it for 20 years first, definitely.

Yes. Interesting counterpoint from Scott Alexander: https://astralcodexten.substack.com/p/please-dont-give-up-on...

Thanks for this! Lots of my peers are going on and on about how we're all doomed. I belisve in climate change, and that it's bad and we must act. But I don't think we're gonna be living in Waterworld, which is what my friends are describing.

There is a pretty major flaw in this write up, which is the assumption that the changes we may see will be linear, be it sea level rise, temps, etc.

There are at least 4 tipping points that could upend this. If the Gulf Stream fails, Europe will be much colder than it is now, for example. Rapid breakdown of ice shelfs could quickly raise sea levels.

“It won’t be bad because it has not yet” is thin.

The middle latitudes are set to be in large part unlivable. Just imagine the geopolitical and humanitarian impacts of hundreds of millions of refugees. Just imagine when a country that is the source of a water source decides they need it and more than others downstream and reroute it.

These are massively destabilizing types of things. And not far fetched.

Sea level rise is the least of it tbh.
