Bitcoin Mining Alone Could Raise Global Temperatures Above Critical Limit By 2033 (vice.com)

dmoberhaus writes: Researchers have found that if Bitcoin is adopted at rates similar to technologies like credit cards, its energy consumption could increase global temperatures by 2C in just 16 years. This is well beyond the limit of catastrophic climate change proposed by the UN. Motherboard spoke to an expert on Bitcoin and energy about the study's implications.

  1. Chill with the arithmetic by reanjr · · Score: 1, Insightful

    Some people need to back off from arithmetic for a sec and take a moment to critically think about what the math is telling you, and how stupid you have to be to believe the math.

  2. One huge unrealistic assumption. by SuricouRaven · · Score: 4, Insightful

    Bitcoin cannot be adopted at rates similar to credit cards, because the network is incapable of maintaining reasonable performance under such a load. It's struggling already.

    Bitcoin, from a technical perspective, actually rather sucks. It's one of the first blockchain currencies, and as such it does not incorporate the performance-boosting refinements that later currencies introduced. It's just like a lot of other technical standards: Once good-enough is established, it's very hard for even a superior technology to replace it. That's why we're still using MP3 and JPEG.

    Man-made warming is not a fantasy.

    Nope, it's a religion, with all the bad connotations there of, especially with the condemnation and persecution of unbelievers.

    We randomly sampled blocks mined in 2017 until their total number of transactions were equal to the projected number of transactions, then we added the CO2e emissions from computing such randomly selected blocks. The approach was repeated 1,000 times.

    They are assuming that The number of blocks mined in 2017 is efficient for the number of transactions and the
      Number of blocks to be mined is proportional to the number of transactions --- More transactions won't result in larger blocks,
    and they ignore innovations that are being adopted like SegWit and Lightning.

    Especially with the ongoing adoption of the Lightning Network; that is not the case --- 2017 of all years is a bad reference year for predicting future growth - expect more transactions with future blocks; If massive transaction volume increases occur again, expect those on the network to eventually agree that a larger block size and other scaling measures are appropriate --- which will result in greater efficiencies or economies of scale with higher transaction volumes.

    The projection the researchers are making is really an uninteresting one: the question their study answers is more like..... What if no changes occurred to the Bitcoin network/protocol for improved scaling, and the predominant way transactions were batched and pooled since 2017 continues indefinitely AND Bitcoin adoption accelerates as projected by the model.

    Climate change is not an "absurd fantasy", you fucking liar. It's scientific fact.

      But is it "man made" ?

      THAT's not as much a scientific fact as a theory that we cannot verify because there is no way to re-run the experiment with different inputs and find out what the cause actually is. I get that folks generally swallow this as fact without so much as a blink of the eye, but it's not straightforward science or without contrary evidence. Remember, coloration does not prove causation, it only suggests it.

  6. You're lying by DogDude · · Score: 4, Insightful

    You're simply lying about climate change. It's 100% real and man made. The climate models that predict the change only work when man-made interference is included. You have no idea what you're talking about. There have been hundreds of thousands of studies that have been included just in the IPCC's reviews, so far. I have no idea what one study you're talking about, and I'm sure you don't, either.

    I know insecure people like to imagine the human race as being so technologically advanced that we could affect the entire planet, but we aren't. AGW is crazy talk by crazy people and not a shred of evidence has even been shown to link humans to anything of the sort.

    In the meantime, the refrigerants that have already caused huge holes in the ozone layer are also some of the worst of the greenhouse gasses, we've demonstrably burned hundreds of millions of years' worth of fossil fuels in a few centuries that would have remained sequestered in the ground indefinitely in anything short of a Permian-Triassic level extinction event, and the oceans are already acidifying enough from the CO2 that shellfish are already impacted.

    You could just go ask around in Alaska, since the polar regions are warming at almost twice the rate of the rest of the globe.

    But first, you have to look at why you're willfully living in a fact-free alternate reality.

    The point was that humanity was verifiably able to impact the entire planet by accident. The assertion of the GGP is that it's impossible in principle for humans to create a global environmental problem.
