Climate-Exodus Expected In The Middle East And North Africa (phys.org) 240

An anonymous reader quotes a report from Phys.Org: Researchers of the Max Planck Institute for Chemistry and the Cyprus Institute in Nicosia have calculated that the Middle East and North Africa could become so hot that human habitability is compromised. The goal of limiting global warming to less than two degrees Celsius, agreed at the recent UN climate summit in Paris, will not be sufficient to prevent this scenario. The result is deeply alarming: Even if Earth's temperature were to increase on average only by two degrees Celsius compared to pre-industrial times, the temperature in summer in these regions will increase more than twofold. This means that during hot days temperatures south of the Mediterranean will reach around 46 degrees Celsius (approximately 114 degrees Fahrenheit) by mid-century. Such extremely hot days will occur five times more often than was the case at the turn of the millennium. In combination with increasing air pollution by windblown desert dust, the environmental conditions could become intolerable and may force people to migrate.

I said that when they *announce* that they are going to move to Canada because of something like an election, they never actually do. It is less of a criticism that they won't ever move when they feel it is right for them to do so than it is a criticism of what they are saying, because what they are saying is usually just so much hot air if it involves actually leaving their home.

        The history of mass migrations suggest that even powerful states can be overwhelmed. Rome, Byzantium, Medieval Islamic civilization and China were all unable to prevent massive amounts of migrant peoples, and where the states weren't outright wiped out, they were heavily damaged.

        Europe can't even cope with migrants from Syria and North Africa as they are. Now imagine what it would take to prevent many times more than that trying to get into Europe. Could Turkey hold them back? If Turkey fails, could the Balkan states prevent millions of people? And what about the Mediterranean, will the British Royal Navy start laying mines and sinking any boat that tries to get across?

        The ramifications of massive migrations out of the Middle East and North Africa for Europe are enormous, and judging by the reactions to current migrations, I think we can see how destabilising and dangerous they will be.

        I don't know if you're kidding or not, but you represent a third of the problem:

        The weather is nice where I am, so I don't think the problem is real

        Then here's another third of the problem:

        The weather is terrible where I am and it used to be fine
        Followed by:
        Oh, well, just because it's bad where you are doesn't mean global warming is real

        Then the final third of the problem:

        Oh hi we're climate scientists! Since you apparently aren't paying attention to what we're saying, we're going to say it louder and be more extreme to try to make you listen!
        Followed closely by:
        Oh, well, you're just being alarmists!

        This is then exacerbated by extremists on both sides of the equation tossing around their conspiracy theories, pseudo-science, tree-hugging anti-human rhetoric, plain old-fashioned politicking, and the religious types who quietly tell you it's all part of "Gods plan", "the End Times are coming", and "soon there will be Heaven on Earth and none of this will matter anymore", or whatever other nonsense they spout. So nothing actually gets done to prove anything one way or another because everyone just keeps arguing. What will 'decide' if it's real or not will be if it either becomes Too Late To Do Anything About It (at which time everyone will continue to argue, this time about whose fault it is), or it just Goes Away On It's Own (in which case everyone will continue to argue, this time about who was wrong, who was right, and why).

      For people, that is true. People are not going to die of the heat. But their crops and pastures will dry out. So the people will either move or starve. The problem is that there is no where to move to. Even Syrians, who are more educated and secular that most other Middle Eastern people, are not wanted anywhere.

      • Exactly. People who point out that Canada will become more arable (eventually) don't usually realize that Canada might not want a large influx of Americans, nor will America want a large influx of Mexicans who can no longer farm their lands. Even assuming the same total amount of land remains capable of producing food, the migrations necessary to get people near those lands will spark several wars and lots of pain and suffering.

      Of course that's only kinda relevant if the temperature increases uniformly which it doesn't [phys.org]

      In the Middle East and North Africa, the average temperature in winter will rise by around 2.5 degrees Celsius (left) by the middle of the century, and in summer by around five degrees Celsius (right) if global greenhouse gas emissions continue to increase according to the business-as-usual scenario (RCP8,5).

      That's ~9F, would you consider that change in your summertime average to be inconsequential? The average high in Baghdad in July is 44C, if the projection is right it will become 49C, I suspect there's a few places you start to consider uninhabitable at that point.

      That isn't how a bell curve works. If you move a bell curve slightly to the left, the big change isn't in the average, but is in how much you have where you end up sampling from the extremes of the distribution. This is why for example, China doesn't have nearly as many top-tier soccer players as some much smaller countries, or how the best runners are almost all Kenyan even though the Kenyan isn't much faster than the average in most other populations. One very controversial example of this is how some populations (e.g. Ashkenazi Jews) have many more Fields Medal and Nobel Prize winners than one would expect naively, but if you move the average intelligence up just a tiny bit, you get a massive change in how many really brilliant people you have.
    • A shift of a few degrees C is nothing
      Says the guy who grasps nothing.

      The link you gave is using Celsius as scale, not Fahrenheit.

      This article is about: if global average increases by 2C then at "hot spots" that might mean 20C or more.

      If at those hot spots such peak temperatures are reached, then the normal seasonal variation has doubled. And the peak is so high that you can't live outside anymore, that is much difference in reality.

      Except we're not talking about Baghdad getting uniformly 2C warmer, every day of the year. We're talking about 60 additional hot days in the summer with the rest of the year being roughly similar to today. Those sixty days would, almost own their own, raise the year-round average by more than 4C (not 2C). For that to happen the temperature increase on these days be closer to +20C, rather than +2C.

      A lot of denialist reckoning does this kind of simplistic reckoning -- e.g., assuming 2C global warming means exactly 2C warmer, uniformly distributed in space and season across the globe. That of course would only amount to a trivial change. But what you're actually going to get is vast increases in extreme weather (hot AND cold) which averaged out across the globe.

      Think of it this way: imagine we hold the global increase in temperature to 2C. The amount of additional kinetic energy per unit volume represented by that additional 2C, integrated over the immense volume of the atmosphere, works out to be a staggering amount of total energy, which will change the patterns of weather. Since that immense fluid is rotating, the additional energy cannot mix and diffuse out uniformly and neatly; instead it will drive massive eddies of hot and cold migrating out of their old geographic limits. You'll get all kinds of extreme weather both hot AND cold, it just all averages out to +2C temperature-wise.

      To put that perspective, current estimates are that we're capturing an additional 8 x 10^21 joules of extra solar energy per year, every single year.

      This literally means that if the temp averaged 90F it will then average 180F. That's a lot of climate change.

      It's worse than that, because 0F is just an arbitrary point on the temperature scale. The only sensible way to interpret a doubling of temperature is relative to absolute zero, so this means that if the temperate averaged 90F (305 Kelvin) it will then average 638F (610 Kelvin).

      That is, indeed, well outside the range of human habitability.

    • It doesn't work like that because it's not an absolute scale.

      First, convert to Kelvin. 90F = 305kelvins. Then you can double it. 610kelvins. Now convert back to Fahrenheit. 610kelvins=638F.
