If you high enough you may reach the controlled environment of the ISS.

Gotta slap on more than a thick coat to go outside, and if you thought a hailstorm could get bad down here..

Anyone know a good web site or publication that shows potential outcomes from all these different changes to global climate and where will be the best places to live in the future? Should i be looking to buy plots of property it Alaska?

The Gulf stream is about making parts of the US east coast and northern Europe warmer. If you like being warm, you can leave those areas, but it's hard to say how much colder they will be or how quickly.

For sea-level rise climate change mitigation, look at topographical maps of coastal areas. Some coastal areas have very quick climbs in elevation as you move inland. Others remain very shallow for incredible distances. The more dense an area is with wealth (think Manhattan), the more likely it is for there to be actual mitigation to sea-level rise like substantial seawalls. But the more dispersed the population and infrastructure is, the less possible that will be.

For precipitation related changes, extreme weather / natural disaster related changes, etc. we don't have much reliable modeling. But consider what the economy and demographics are like in the area you reside in, how much existing poverty or famine there is, how reliable infrastructure is, and whether your area is a net food importer or net food exporter and how much margin it has to undergo decreased agricultural productivity and still feed itself. Consider the ease or difficulty with which net-food-importer-region displaced refugees would be able to migrate to your area, as well as the size of such populations.

If shit actually hit the fan, I assume they'd have to worry about insider threats from their staff.

Isn't the trick to have a dead-man switch installed in your person which blows up the compound in the event that you're killed (or die of natural causes I suppose)? I'm sure they've thought through a lot of scenarios already.

Every human built thing (and almost every built thing is human built) can be 'unbuilt' by humans, often quickly and trivially. See door locks.

The only sure way to protect yourself is to be part of a society - something our hunter gatherer forebears quickly latched onto.

- Accelerated ice melt - The Gulf Stream brings warm water near Greenland and Antarctica. Its weakening could disrupt this process, potentially speeding up ice sheet melt. I don't understand this one. Why would the reduction in warm water brought to Greenland cause the ice sheets to melt more?

had to think about this a bit. It doesn't directly affect it, but it adds to the problem of global warming by increasing the temp gradient between the higher elevation interior and the cooler, lower elevation coast. This can cause more wind and increased evaporation, and, effectively, "pull" the damp air away from the central ice sheets.

But that's just me speculating. It definitely seems counterintuitive.

Altitude not latitude. Alaska would be a somewhat bad spot to live if AMOC slows way down. You want places where the local climate is not driven by the ocean or air currents, meaning there is very little air above them. Think Bogota, Quito, Addis Ababa etc.

Every local climate is driven by air currents, by which I assume you mean jet stream changes driving pressure changes...aka cold/warm fronts. The jet stream is significantly controlled by the heights of the Alps and the Rocky mountain ranges in the northern hemisphere and the air currents are driven by the Earth's rotation. The Earth is not going to stop rotating and the mountains are not shrinking. This is why weath…

I agree the air currents matter. But at those altitudes the sun has a much larger impact than at lower ones. The models that rate places by impact consistently list high altitude cities with lower impacts.

Aren't all the oligarchs building their escape bunkers in New Zealand?

lol probably not the most geologically safe location to build such a thing.

I mean given what we know about the Sahara and its wet and dry periods, it doesn’t seem at all illogical that ocean currents should start and stop to match. I think it’s important to understand that the earth is deeply dynamic and constantly changing, and has incredible variation in often cyclical patterns over hundreds, thousands and tens of thousands of years. While we know human caused elements are accelerating tr…

Pathetic. Cited references with evidence and nobody even wants to look. Climate is incredibly complex. Stop looking at this whole issue one dimensionally.

I can’t imagine how you’d all react to my Native American friends who are all talking about a coming ice age. They think the opposite is about to happen.

Society is the first thing to break down in a disaster situation though.

Yes, the EU will forbid the sale of new petrol vehicles starting in 2035.

Which is reasonable even if there was no climate catastrophe at all, I really hope I can fully experience unpolluted and much more silent inner cities in my lifetime! Anyway, regarding your freedom, you are free to leave to more free countries, where you can also have your leaded pipes and other unhealthy great things back!

For the cities, I'm kinda hoping cars will be banned altogether or made really expensive like London has done. Especially in cities with amazing public transport there's no reason to have so many cars around.
