Deforestation Has Killed Half a Million People in Past 20 Years, Study Finds (theguardian.com) 68

Deforestation has killed more than half a million people in the tropics over the past two decades as a result of heat-related illness, a study has found. The Guardian: Land clearance is raising the temperature in the rainforests of the Amazon, Congo and south-east Asia because it reduces shade, diminishes rainfall and increases the risk of fire, the authors of the paper found. Deforestation is responsible for more than a third of the warming experienced by people living in the affected regions, which is on top of the effect of global climate disruption.

About 345 million people across the tropics suffered from this localised, deforestation-caused warming between 2001 and 2020. For 2.6 million of them, the additional heating added 3C to their heat exposure. In many cases, this was deadly. The researchers estimated that warming due to deforestation accounted for 28,330 annual deaths over that 20-year period.

    Don't look at me like that. I did say "timber"!
    • A tree was felled, and killed a man. Since 1980, 18,000,000,000 trees were felled. Ergo, 18,000,000,000 men were killed by deforestation.

    While I agree that deforestation is bad and causes problems, saying "Study Finds" implies far too much certainty
    Popularizers of science tend to report speculation, calculation, estimation or simulation as proven truth
    Scientists are more careful about presenting their findings

    • Gotta admit I didn't even bother to read the article but this sort of thing is usually more actuarial than empirical if that makes sense.

      Also since you're nitpicking. The vast majority of generally accepted scientific theory is not regarded as the proven truth. There's a specific meaning to the words you used.

      Indeed.

      It's kind of like these ads for nutritional supplements that claim all kinds of miraculous benefits. But when you look at the fine print, what you see is that they do a whole lot of extrapolation, something like this: "Garlic contains numerous beneficial healthful ingredients that (generally speaking) benefit humans in numerous ways (some listed in the ad). Therefore, taking our supplement is responsible for all of these same benefits." Sure, those nutrients are important and play a role in human hea

        oh, look at the trumper who joined in. Now, lets not agree that any damage could actually be done, right?

        • What kind of self-respecting Trumper would say that global warming is harmful?
          Also, what kind of self-respecting Trumper wouldn't be all-in on nutritional supplements (and shunning of the well-tested medical science behind vaccines)?

          I don't think you understand Trump-supporters as much as you think you do.

          I didn't say that no damage could be done. I said it's not valid to calculate a number of people who died because of deforestation. That is too many logical leaps to substantiate.

    • But I read enough to get the gist. Deforestation means higher temps and that means people who can't afford ac get sick and die.

      The numbers are probably correct. It wouldn't be hard to compare great strokes from before the deforestation to now.

      Heck, parts of India are going to be unlivable soon.

      in other words, deforestation may be bad as a matter of opinion, but let's not call anyone's attention to it.

    The flip side that I don't believe many want to acknowledge is that the same actions also lifted several million out of poverty or otherwise saved/lengthened their lives. There's very little we do that has purely positive or purely negative effects. The real world is rarely so black and white and the choices we have a a series of compromises and tradeoffs. A person who is facing starvation tomorrow is not going to care about what the world will be like next year, much less 100 years, as a consequence of them trying to stay alive. Of even less concern is what bad things anyone posting about it on the Internet has to say about them. They're not going to stop making those decisions either unless they have a better alternative and navel gazing ain't it.
    • Humanity needs to have discussions about where we're at as a species and start quantifying the externalities we've produced along the way, hang back, and correct those.
      That is if it is humanity's desire to exist comfortably into the future. Let alone achieve the lofty goal of populating other worlds.

      Personally I think humanity has a death wish so intrinsic to it's collective being that it's hardly aware of it's own hands tightening around it's neck.

        Humanity does not have wishes or desires. Many individual humans have those things. They are far from the same, and they are not at all interchangeable.

        • Humanity collectively behaves as it is made to.
          If you look at a swarm of mice strange dynamics emerge. Eating, fighting, fucking, and then moving on in a panic to the next source of food until everything is gone. Group behaviors.

          I think we're the same. Go ahead and prove me wrong, go be the one fuck who gives up his meat, cars, planes, and walks around home bundled up in the winter. Will you you change your behaviors or will you decide the guy next to you is gonna blow through your share of the planet

            No argument here, I will not be that person. This is the best time ever to be alive and damn right I'm going to enjoy my short time here. I suggest others do the same. Human civilization is a limited time offer.

            It is going to come crashing down, or at least life will not be as great for many people in the future. Personally I think climate is the least of their worries at the rate they are sleepwalking into a shithole dystopia. If anything climate is simply another means to that end.

            • I think we can and should stop ourselves but it would be a global effort and require international cooperation, I’d take giving up or paying more under those circumstances but it’s not gonna happen and I hope our grandchildren don’t forgive us. I hope that as things get bad the ones living though it tear down monuments to supposedly great men. Captains of industry, presidents, etc.
              I wish they could show us.

    • lifted several million out of poverty

      I gotta admit, I am suspicious of this claim. Do you mean to say that people who were living sustainably off the land are better off now that they are participating in our economic system and paying for food?

      I would say that they were enslaved.

    1) The Guardian isn’t exactly known for even handed analysis.

    2) The world’s overall vegetation is 10% higher than it was 25 years ago, due to reforestation, etc. That’s the equivalent of adding a new Amazon rainforest.

    3) FAR more people die each year due to cold waves than heat waves. The ratio is about twenty to one according to some estimates.

      The Guardian is complete crap, as is the study they are referring to

        Those are simply blanket statement’s that, in of themselves are objectively true, but ultimately add zero to the conversation. They do not, for example, add any context that isn’t already extremely obvious to anyone reasonable, and do not in of themselves empirically prove your supposed point that reforestation isn’t helpful and relevant in this context. This is a variation of classic DARVO - deny, invert, and attack. It isn’t good faith argument - it’s just intended to shore u

  • To reduce the deforestation we should redouble our efforts in rooftop solar, offshore windmills, battery energy storage systems, electric vehicles, and so much else to lower our CO2 emissions, reduce air pollution, and avoid digging for coal and uranium.

    One thing concerns me though, where are we to get all the lithium and rare earth metals for these things?

  • It just goes to show you... you do not want to piss off the Ents!

  • That's the claim. A difference of 3 C killed 25,000 people a year for 20 years. Do you believe it?

    Assuming it is correct that 3C was the aggregate increase over the 20 years they looked at, or 0.15C/year.

    By way of comparison the temperature range in New York City just for today was 10C.

  • The Guardian, when it claimed to be part of the resistance, lost credibility. They have points to prove and choose the appropriate stories to publish.

  • Have populations in those areas increased because of access to more resources? Does chemo-therapy kill people? Does plastic kill people? Does petroleum kill people? Do vaccines kill people?
