Where More People Will Die -- and Live -- Because of Climate Change (washingtonpost.com) 131

An anonymous reader shares this thought-provoking article by a graphics reporter at The Washington Post who was part of its Pulitzer Prize-winning Explanatory Reporting team: The scientific paper published in the June 2021 issue of the journal Nature Climate Change was alarming. Between 1991 and 2018, the peer-reviewed study reported, more than one-third of deaths from heat exposure were linked to global warming. Hundreds of news outlets covered the findings. The message was clear: climate change is here, and it's already killing people. But that wasn't all that was happening. A month later, the same research group, which is based out of the London School of Hygiene and Tropical Medicine but includes scientists from dozens of countries, released another peer-reviewed study that told a fuller, more complex story about the link between climate change, temperature and human mortality. The two papers' authors were mostly the same, and they used similar data and statistical methods.

Published in Lancet Planetary Health, the second paper reported that between 2000 and 2019, annual deaths from heat exposure increased. But deaths from cold exposure, which were far more common, fell by an even larger amount. All told, during those two decades the world warmed by about 0.9 degrees Fahrenheit, and some 650,000 fewer people died from temperature exposure....

But whose lives? Projections indicate milder temperatures may indeed spare people in the globe's wealthy north, where it's already colder and people can buy protection against the weather. Yet heat will punish people in warmer, less wealthy parts of the world, where each extra degree of temperature can kill and air conditioning will often remain a fantasy....

What about the long term? A groundbreaking peer-reviewed study, published in November in Harvard's Quarterly Journal of Economics, gives us a glimpse. In the study, a team of researchers projected how mortality from temperature would change in the future. The worldwide temperature-linked mortality rate is projected to stay about the same, but you can see enormous geographic variation: colder, wealthier countries do well, while hotter, poorer countries suffer.

          Wrong on many accounts.

          First, cold is easy to compensate for even with low levels of technology. You just burn something. Heat is easily generated, but more difficult to get rid of. In fact, especially with cheap fuels of all kinds (fossil, wood, whatever) it's easy to heat something, but cooling requires something else.

          Second, most of the cultures living in hot climates have aeons-old techniques for cooling, at least to a livable temperature. But these techniques don't mix well with high-density urbanism.

Look at covid, it spawned anti-asian racism, and waves of nationalism even though it should have helped get people together (in spirit at least, not physically). And Nazism was a direct consequence of Germany's ruin following WW1.

    • Not quite. Because it's colder in the North, that's where people in prehistory became more familiar with the long-term uses of fire, which produced empires and wealth. Those advantages eventually led to industrialization and mechanization in modernity, which in turn is driving global warming. So, while there's clearly a conspiracy to ignore the problem and maintain the status quo, the actual problem itself has not stemmed from deliberate acts against the global South.

And it cannot be a solution for all those poorer to storm the beaches and borders of the richer nations, it simply will not work to increase the concentrations even more.

      That problem is in the process being solved already; global fertility rates are dropping. The global average fertility rate is around 2.3 children per woman today, and there are no signs that it won't continue to drop. The key element in this drop was simply access to birth control, but decreases in global poverty also helped (poor people have more children than rich people.)

And this efficiency has been going up about 3-5% yearly for several decades. At least in part because food ultimately comes from photosynthesis, which is optimized for around 1500ppm CO2 air content.

          From IPCC reports (rather than the shit that politicians spew), climate change is a normal event that is supposed to be happening in the wake of ice age we just exited. The problem is that CO2 we're putting into the atmosphere in the wake of technological revolution accelerated it too much, resulting in rapidity of change that means that normal dying off is slightly accelerated, seemingly outpacing emergence of new species better adapted for changing environment. Data is inconclusive, because we don't have good data on amount of new, better adapted species and subvariants, and this judgement cannot be made without understanding both parts of the fomula.

          I.e. your doomsaying is both anti-factual and anti-scientific. But it's very popular in popular culture circles. As an example of lack of "dying off", in general as planet warmed and became more saturated with CO2 in atmopshere, total amount of organic life increased. I.e. the opposite of "dying off" happened. We are currently observing this with our satellites. As observed from space, planet is greenest it's ever been. As greenery is the basis for almost all calories that organic life on this planet consumes to power its existence, it's also reasonable to assume that there has never been more organic life on this planet since we started observing it from space.

          • The great "dying off" which is talked about is about diversity, especially species which can't adapt to climate change, NOT about total biomass. In fact if you had an explosion of algae killing all species in the ocean but having twice the biomass, it would not be "good" it would be terrible and a great dying off.

              The vast majority of the 'greening' is happening in arid areas, where the higher concentrations of co2 allow plants to acquire co2 with less loss of water.
              Increased co2 is also increasing crop yields with no additional labor or use of fertilizers.
              It has also revealed an unexpected counter-balance, as plants with access to more co2 put more growth into roots. As plants decay, generally the parts above the ground go back to the air, and the parts below the ground stay to enrich the soil. As such, the more c

  • Interesting analysis.

    Take away point is that in fact, not all effects of global warming are bad in all regions; it will have both good and bad effects in different places.

    From that, I'd expect a lot of migration (or attempted migration) of refugees from near-equatorial to temperate regions. This will be disruptive.

    But personally, I'd be more worried about effects on the global food supply, not on simple heat-related deaths and cold-related deaths.

It can, and has been done, but they're going to need some alternative source of money to buy food with until the land becomes productive again.

    • In that case, the difference between heat/cold deaths would probably widen another order of magnitude. Because if we did, we’d have to attribute a good chunk of COVID deaths (and other annual flu/cold deaths) to cold temperatures, since cases and deaths of communicable disease such as those always skyrocket when temps dip below freezing. That’s why they call it “cold and flu” season, because it forces so many indoors.
