  • I repeat: Live thrived under much harsher conditions in the past. It will not suddenly die out. I find your pessimism unfounded. I’m sure humankind will exist for at least another millennium.

    Ocean acidification will not kill all algae. They existed for much longer than most other forms of live. They survived the +14 °C 300 million years ago, guess how acid the oceans were back then. Also about 300 million years ago oxygen levels in the atmosphere peaked at about 35 % indicating a very strong production by plants. The algae species from back then are still alive today!


  • Watch Sabine Hossenfelder’s videos about climate models on YouTube: https://youtu.be/4S9sDyooxf4

    +3 °C just means that the average temperature on Earth increased by that on average. There are places where the increase is higher and there are places where the temperature dropped. And then there are other places where the weather will be more violent than it was in the past.
    The melting of permafrost in Russia that keeps methane trapped will probably be a problem in the future but that’s still several decades or even a century away. The release of methane will not kill us. But it might kill a lot of species.

    It’s not the temperature that’s the problem, it’s the rate of change. Flora and fauna can’t adapt that fast. 10 000 years would be enough time to adapt to +3 °C but it’ll happen within only a 150 years time span.

    Humans on the other hand will just install an air con and be done with ‘adapting’. Some coastal areas will be flooded and some hot places on Earth will be too hot for humans but everywhere else will stay ‘ok’.

    Live on Earth will survive. There were times when temperature and atmosphere conditions were way more extreme and even toxic for humans. But the dinosaurs thrived in that conditions!



  • Song says it appears that the world’s oceans are losing their ability to dissipate heat from the surface into the deep ocean.

    But isn’t it obvious that there’s a limit how much heat the oceans can store? Actually it can only get rid of it by emitting it into the atmosphere/space.
    Additionally the hotter the water gets the more energy it emits which should slow down the net energy absorption.
    As those two effects are opposites of each other there should be an equilibrium temperature where they cancel each other out. Currently it seems the oceans are a bit away from that equilibrium. It should swing the other way in a few decades or so. The oceans are big that’s why it takes time for change to manifest.

    For me it sounds like the journalist didn’t really understood, what Song researched or tried to make a click bait article.













  • Is SSD really necessary? Everything I search up says SSDs have worse retention than HDD in cold storage. A couple TB of HDD is pretty cheap these days, and seems like a better cold storage option.

    SSDs are by design less susceptible and more robust. No moving parts and able to work in much harsher conditions than hdds will ever be able to. The standard set by JEDEC requires every consumer ssd to have a 1 year data retention while powered off at 30 °C (I think). That’s the minimum it has to archieve but usually they are better than that. Do not buy the cheapest thumb drives because they contain the all the crap that wasn’t good enough to make ssds from it.
    Btw you need to fire hdds up regularly too or the motor gets stuck. I think every 3-6 months was the recommendation.

    Yes, so now I’m thinking a rotation cycle. About every 5 years replace the drives with new ones, copy over all data.

    Don’t make it flat every 5 years. Let a software monitor the SMART values of the drives and send notifications if the values indicate an increased change of a dying disc/ssd.

    Does this matter if I have a SATA->USB cable stored with it?

    Those are the first that fail, followed by the usb controller chip in the tray. Keep it as simple as possible. Removable trays are probably the best way but I’m not sure how much wear they can take.

    Do not buy 2.5" drives. This class will die out soon™. There were no new hdds introduced in years and ssds are often replaced by M.2 ones because of the faster connection.
