Technically summer doesn't start until June 21.

Summer solstice? That's midsummer , not the start of summer.

At least in Europe the summer solstice is regarded as the beginning of summer. It takes months for the land and water bodies to warm up, so this definition makes the seasons line up with temperatures observed in Europe. Depending on geography it might make less sense elsewhere, just as not every place has four seasons.

Yep I think mass migration is inevitable. Given the absolute mess migration was out of Syria into Europe (and that was comparatively minor) I think it's going to be unpleasant. Once it starts it'll snowball as well instead of an orderly evacuation it'll be pell-mell. Sometimes think it would be nice to have a single rational world government so that we could deal with these things on a species level. Of course if we…

> Of course if we had a single rational world government for any length of time we wouldn't be in this mess. No, you would be in another mess.

That other mess might be preferable. I'd say this will get bad, but that wouldn't cover it. We might well see gigadeath.

Would you write the same thing about Houston or Paris? If not it’s just racist.

Houston and Paris are not races.

Now, this is what I generally qualify as the "that's not racist, it's bigoted" pedant's defense.

And it really doesn't carry quite as much weight as people apparently think it does.

This is how all organisms’ population dynamics work. They expand until they meet their boundary conditions.

In humans case, we may actually be making our boundaries smaller and smaller by changing the planet.

Would it be a tragedy if humans went extinct?

They will turn into refugees. That's part of why we expect hundreds of millions of climate refugees in the coming decades.

I fully agree with you, but thought that the words "out of Syria" are not really reflecting reality. According to Wikipedia[1], only about a third of the migrants originated in Syria.

I remember reading a sci-fi story back in the 80's (damn I wish I could remember the name) where that basically happened, Europe and the US fortified their borders (massive walls/fences, automated weapon systems, usual sci-fi fare) and left the rest of the world to it's own devices. I was only a kid and I remember thinking "I can't imagine that ever happening" then I look at the refugee camps in EU states (Greece par…

This has been a plot of quite a few novels, so I'm struggling to come up with that exact one (if I've even read it). Off the top of my head, Children of Men is similar.

It definitely wasn't Children of Men, I read so much pulp sci-fi back then it all blurred (except for the stand out stuff like Iain M Banks - I still remember exactly where I was when I read Consider Phlebas - At the caravan park near Pevensey Bay in 1989, book was a birthday present).

These temperatures in high humidity can be deadly even to healthy and fit humans as our bodies are left without a way to cool down. Currently, they have humidity around 10-20% so it affects the most vulnerable, but global warming may lead to making parts of the world literally deadly to every human being... https://en.wikipedia.org/wiki/Wet-bulb_temperature The wet-bulb temperature (WBT) is the temperature read by a…

What caused Chicago of all places to reach that temperature?

This has been the case almost every year this decade in India.

Also, it is quite common for the government departments to fudge data and report temperatures > 50 Celsius as 49.x to avoid halting work / paying extra to those working under the Sun because there are regulations concerning this.

Edit: I got to know about this practice being rampant through an activist in the South who is well versed with the labour laws.

If this happens frequently enough in sufficiently populated areas, then the resulting population die-off will eventually reduce the energy need and resulting carbon outlet and things may stabilize. Sucks for the people involved. But globally speaking, it may not be so bad.

People are mobile. What would actually happen would be the biggest refugee crisis the world has ever seen. Imagine tens of millions of climate refugees at the border of many different countries, and the choice is to let them in and take care of them or let them die right there. It's not a good situation to be in. Realistically speaking, with that many people, good luck keeping them out.

It's really interesting how this doesn't seem to occur to some people even in this HN discussion, even in the context of the recent refugee waves to Europe and the illegal immigration situation in the US. Boggles the mind that someone would think that entire populations would just… lay down and die or something!

In dry climates with such hot temperatures, staying hydrated and sweating will keep you cool (or rather, keep you cool enough to not die). What happens when temperatures like these are reached in high humidity zones where sweat just sticks? Will we simply have entire communities that lack air conditioning dying off?

They will turn into refugees. That's part of why we expect hundreds of millions of climate refugees in the coming decades.

The wall our president wants to build has nothing to do with current immigration trends. They’re banking on this future.

Steve Bannon has this book he’s always talking about, The Camp of the Saints. It’s the clearest and most concise guide for how they see the climate future rolling out. (This is also why I bristle when they get called climate change deniers. They’re not, they just reached different conclusions.)
