Persian Gulf Temperatures May Be At the Edge of Human Tolerance In 30 Years (arstechnica.com)
An anonymous reader writes: According to a new climate study the Persian Gulf may become so hot and humid in the next 30 years that it will reach the threshold of human survivability. Ars reports: "Existing climate models have shown that a global temperature increase to the threshold of human survivability would be reached in some regions of the globe at a point in the distant future. However, a new paper published by Jeremy Pal and Elfatih Eltahir in Nature Climate Change presents evidence that this deadly combination of heat and humidity increases could occur in the Persian Gulf much earlier than previously anticipated."
The human body needs periods of cool temperatures to recover from being in the heat. The effects are also more severe as the heat increases and the humidity reduces the ability of the body to cool itself. When it's very humid, temperatures don't fall as much as night, which prevents the body from recovering during that period. Humans can tolerate periods of hot and even humid conditions, provided they also get time to cool off and recover. The excessive heat and warm nights due to the humidity are a bad combination. While you can tolerate a really hot bathtub, you certainly wouldn't survive being in one all the time.

Science is INTERESTING, chaos theory even more so, and it's easy to see the changes if you know what to look for. The increased energy in the system is already turning all of weather to a parade of freak outliers and unpredictable quirky events that occasionally spike off the charts, and that's exactly in line with the 'chaotic system' model.
I wouldn't have called the 'Earth turning to an alien planet that doesn't support life' thing in thirty years, but if you specify it's to happen in particular (unusual areas) then I'll believe that. Some areas of the planet are already close to uninhabitable and it doesn't take that much to push 'em over the brink. The thing to watch for is not places being rendered uninhabitable by weather extremes, it's more about masses of people/animals displaced because the change is a new thing that nobody's prepared for.
You can probably, right now, buy a 40-year lease on land that might as well be the Moon in 40 years. If you want a real picture of the plausibility of man-made global climate change, don't check scientists or Al Gore, consult actuaries and insurance companies. Pretty sure you'll find they're believers, because they have to actually pay for it if they choose wrong.
Make sh*tloads of money selling fossil fuels to the rest of the world...
Parlay that money, and valuable commodity, into unwarranted global influence...
Have homeland rendered uninhabitable by the consequence of burning said fossil fuels...
..thats one way of solving conflict in the Middle East
You mean one way of causing the conflict in the middle east to escalate and start spreading outward.
Right... and if anybody thinks the Middle-East->Balkans->Europe or S-America->Mexico->USA migration is a problem now try to imagine what it will be like when large of South America become deforested and the Middle East becomes an uninhabitable dustbowl. Everytime I hear somebody make that: "It's not our problem, let them kill themselves down there, the best thing we can do is not interfere" like the OP I'm tempted to bring up the mess that is Syria which to a large extent became the mess it is because we listened to people who recommend apathy. Interfering is bad but at least you have some influence on the course of events, not interfering is worse because by not interfering you let the situation spin completely out of control.
The Persian Gulf is actually hotter and more humid. One city in Iran had the heat index soar to 163 degrees this past summer.
Yes, it gets very hot in parts of the US in the summer. The Gulf Coast states are very humid. It can get just as hot in the Plains, and the evapotranspiration from crops like corn can raise the dewpoints into the low 80s at times. I've experienced this living in Nebraska. But it still isn't as hot and humid as the Persian Gulf.
The other difference is that there's widespread air conditioning in the US. People still die, but it's mitigated because of the air conditioning. There's far less availability of air conditioning in the poorer countries of the Middle East. Sure, the wealthy nations like Kuwait, Qatar, and the UAE have plenty of air conditioning. But the same can't be said in places like Iraq and Yemen. Add to it a severe water shortage and there's potentially a big problem. The weather is worse than anywhere in the US, and the socioeconomic issues make it even worse.
Well, we already did enjoy nice bottles of English wine. In the medieval warming period, vineyards were all over northern England. Today, many street names still have names of grape varieties as a result of those times.
Oh, crap. We can't talk about that. Nevermind.

Its difficult to explain anything to people that can't be summed up into one sentence or a short five sentence anectdotal story.
That said the basic thermodynamics of added CO2 and other heat trapping gasses is simple, well understood, and was settled long ago academically. The real cutting edge research today is determining what will happen on a regional scale. In the above study published in Nature, it's not an increase in temperature so much as its an increase in regional moisture brought on by a slight warming and a shift in climate.
It's not a dust bowl effect, think of how bad that dry heat is going to be if it turns high humidity.
While results like these could be more accurately modeled, say by having better satellites, far more money is spent arguing than buying hardware and funding research. The possible doomsday scenerio isn't a whole planet that's too hot - its far more likely a slightly insane nuclear arms bearing nation essentially being locked inside a car with the windows rolled up in a Flordia kmart parking lot in July.
No we weren't. The "coming ice age" thing was an article written in the popular press and was never supported by climate science.
In reality, climate science was already talking about anthropogenic global warming way back in the 1970s.

your misusing and abusing information to make a flawed point.
"geological global average was higher than today" .... when you use a 600 million year time period.
hint: 600 million years ago complex multicellular life (things above bacterial mats and algae) didn't even exist yet.
And why just 600 million years? If we're going to geological time scales, why stop there? Why not go back further? to the cooling earth after its molten formation? Or was it just to conveniently leave out the 200 million year long glaciation period that occurred just before the arbitrary 600my cut off?
same for CO2 levels. yes, it was warmer and higher CO2 millions of years ago....and life that evolved for those conditions existed. the problem is the current situation is in not operating on evolutionary time scales. its not just the existence of the conditions, but the speed. those prior conditions occurred over hundreds of millions of years, which is actually a point supported by the very things you mention, and unlike the current conditions and trends.
and further: you're using geological time scale global averages, when the article in question is talking about a specific point in time at a specific place...the total opposite. The fact that the global average is ok for humans doesn't contradict or prevent the existence of locations not habitable by humans, places like Antarctica or the Middle East.
in short: just more unscientific denier BS.
The guy who said the election was rigged won the presidency with the second-most votes.
So basically, you want the Americans to channel the shittiest of all dictators and along with their bombings, occupy and terrorize a population. And this is marked insightful? Disgusting.
I get it. That barbaric culture is scary. You're afraid of them breeding like rabbits and establishing sharia law after immigrating to your country. If you react in this way, there is literally nothing separating you from the terrorists. Their ideas are your ideas. You literally WANT TO TERRORIZE THEM INTO SUBMISSION.
How the fuck is this insightful? Consider if someone was saying this about the US. You just know that even though you'll subjugate the majority, you will always have an armed rebellion for as long as you're there. Legitimately fighting their brutal occupiers. If The US saw Russia doing that, they'd call them brutal aggressive occupiers and that's what you'd be.
There are better options. They are harder, complex and don't give you the satisfaction of the genocide you crave. Fear leads to anger. Anger leads to hate. Hate leads to suffering. It may be from a movie but it's the goddamn truth. Real solutions are harder than that but maybe we humans haven't reached a level of emotional or intellectual maturity to use them yet.
But it won't kill everyone as you suggest.
You missed his point - If you can't survive for more than a few hours at a time outside, what happens when you lose power for a week?
Answer: Everyone dies. Or at least, a high enough percentage of the population to make the distinction irrelevant.
In reality, climate science was already talking about anthropogenic global warming way back in the 1970s.
In reality, it was being discussed in Los Alamos during the 1940's. Early climate models suggested that we hadn't even begun to notice the effects [of all the deforestation during the Industrial Revolution over a century earlier]... but that we certainly would. It should be noted that this "braintrust of brilliance" (the world's top physcists were of course gathered there) was also discussing what we might be able to do to offset the effects...
