        No, also the massive SO2 that Mt Pinatubo put into the atmosphere slowly went away. And the CFCs.

        Pinatubo created more sulfur emissions during its eruption than 10 years of all human coal burning.

        And also on top of that we were also wrecking the Ozone.

        Nature can always make our mistakes much much worse.

      It’s the same as people using the example of the Y2K bug being a non event. Yeah, because globally trillions of dollars were spent fixing it before it became an event.

            Did you even bother to read it?

            Among other things it says: “Based on the Montreal Protocol and the decrease of anthropogenic ozone-depleting substances, scientists currently predict that the global ozone layer will reach its normal state again by around 2050.”

            The reason it isn’t discussed as much is because it’s on the mend and the only things newsworthy are the larger than normal cyclical hole that forms. Another thing mentioned was a volcanic eruption in 2022 that is believed to contribute to that “larger than normal” hole.

            Nothing there disputes the fact that we took action. I worked as a refrigeration tech and we even had to learn about this before we could be EPA certified to handle refrigerants.

          Yes, most administrative programs, think hospitals, municipal, etc had a year set only in 2 digits. Yesterdays timestamp will read as 99 years in the future, since the year is 00. Imagine every todo item of the last 20 odd years suddenly being pushed onto your todo list. Timers set to take place every x time can’t check when last something happend. Time critical nuclear safety mechanisms, computers getting stuck due to data overload, everything needed to be looked at to determine risk.

          So you take all the dates, add size to store additional data, add 1900 to the years and you are set. In principle a very straight forward fix, but it takes time to properly implement. Because everyone was made aware of the potential issue IT professionals could more easily lobby for the time and funds to make the necessary changes before things went awry.

              Depends on the “they”…

              But generally, back in the day data storage, memory and processing power were expensive. Multiple factors more expensive than they are now. Storing a year with two digits instead of four was a saving worth making. Over time, some people just kept doing what they had been doing. Some people just learned from mentors to do it that way, and kept doing it.

              It was somewhat expected that systems would improve and over time that saving wouldn’t be needed. Which was true. By the year 2000 “modern” systems didn’t need to make that saving. But there was a lot of old code and systems that were still running just fine, that hadn’t been updated to modern code/hardware. it became a bit of a rush job at the end to make the same upgrade.

              There is a similar issue coming up in the year 2038. A lot of computing platforms store dates as the number of seconds since the beginning of 1970-01-01 UTC. As I type this comment there have been 1,710,757,161 seconds since that date. It’s a simple way to store time/date in a way that can be converted back to a human readable format quite easily. I’ve written a lot of code which does exactly this. I’ve also written lot of code and data storage systems that store this number as a 32bit integer. Without drilling down into what that means, the limit of that data storage type will be a count of 4,294,967,296. That means at 2038-01-19 03:14:07 UTC, some of my old code will break, because it wont be able to properly store the dates.

              I no longer work for that employer, I no longer maintain that code. Back when I wrote that code, a 32bit integer made sense. If I wrote new code now, I would use a different data type that would last longer. If my old code is still in use then someone is going to have to update it. Because of the way business, software and humans work. I don’t expect anyone will patch that code until sometime around the year 2037.

                A little nitpick: the count at that time will be 2,147,483,647. time_t is usually a signed integer.

                I often wonder what happened to the code I wrote in 2010 and used for production coordination & was working fine when I retired (2018). I figured the minute I left the hotshot kids would want to upgrade to their own styles. Not everyone liked it bc it wasn’t beautiful but no one could say it wasn’t functional, so it persisted. I was busy learning design and assemble CNC routers; but it worked and I didn’t have time to make a selection of backgrounds & banners. It’s just Excel, AutoCAD, & Access using VBA, which everyone has says they are going to deprecate VBA but, alas, people still want it. I remember Autodesk announcing the deprecation of VBA c. 2012 and I just looked and I guess they changed their mind bc there are modules for VBA available

              The Mayans figured a calendar that only went to 2012 would be good enough. And they were right, their civilization didn’t exist anymore in 2012. Only relevance their calendar system had in 2012 was that some people felt like it was a prophecy about the end of the world. Nope, just was an arbitrary date the Mayans rightly assumed would be far enough away it wouldn’t matter.

              While I suppose you could make a date format that was infinitely expandable, it would take more processing power and is really unnecessary.

              Anyway got until 2038 until we’ll have to deal with a popular date format running out of bits. We’ll probably be in some kind of mad max post apocalyptic world before then so it won’t matter.

                That’s a misconception. The Maya (not Mayan, that’s the language) long count for December 20, 2012 was 12.19.19.17.19. December 21, 2012 was 13.0.0.0.0. Today is 13.0.11.7.4. It continues the same way indefinitely, it’s just the number of days since some arbitrary date (August 11, 3114 BCE if you’re curious) in base 20, with the second to last digit in base 18, which seems odd at first but it rather cleverly makes it so the third digit can stand in as a rough approximation of years, and the second is approximately a generation. Now October 13, 4772 could be seen as an endpoint but there’s nothing that says it can’t be extended with one more digit to 1.0.0.0.0.0, and then you’re good for another 150,000 years or so.

                Now there was a creation myth that said 0.0.0.0.0 was the previous world’s 13.0.0.0.0, but there was no recorded belief that this was any sort of recurring cycle, in fact plenty of Maya texts predicted astronomical events millennia past 2012. The idea that it was recurring was probably borrowed from the similar Greek construct of ekpyrosis, which doesn’t specify any sort of time frame.

            You’re saying “imagine” a lot there.

            Were there concrete examples of critical software that actually would’ve failed? At the time I remember there was one consultant that was on the news constantly saying everything from elevators to microwaves would fail on Y2K. Of course this was creating a lot of business for his company.

            When you think about it storing a date with 6 bytes would take more space than using Unix time which would give both time and date in four bytes. Y2K38 is the real problem. Y2K was a problem with software written by poor devs that were trying to save disk space by actually using more disk space than needed.

            And sure a lot of of software needed to be tested to be sure someone didn’t do something stupid. But a lot of it was indeed an exaggeration. You have to reset the time on your microwave after a power outage but not the date, common sense tells you your microwave doesn’t care about the year. And when a reporter actually followed up with the elevator companies, it was the same deal. Most software simply doesn’t just fail when it’s run in an unexpected year.

            If someone wrote a time critical safety mechanism for a nuclear reactor that involved parsing a janky homebrew time format from a string then there’s some serious problems in that software way beyond Y2K.

            The instances of the Y2K bug I saw in the wild, the software still worked, it just displayed the date wrong.

            Y2K38 is the real scary problem because people that don’t understand binary numbers don’t understand it at all. And even a lot of people in the technology field think it’s not a problem because “computers are 64 bit now.” Don’t matter how many bits the processor has, it’s only the size that’s compiled and stored that counts. And unlike some janky parsed string format, unix time is a format I could see systems at power plants actually using.

              This comes to mind:

              You don’t store dates as Unix time. Unix timestamps indicate a specific point in time. Dates are not a specific point in time.

                You also don’t store dates in a string that you’ll have to parse later. I’ve had to deal with MM-DD-YYYY vs. DD-MM-YYYY problems more times than I can count.

                And you understand that you could have a date in unix time and leave the time to be midnight, right? You’d end up with an integer that you could sort without having to parse every goddamn string first.

                And for God’s sake if you insist on using strings for dates at the very least go with something like YYYY-MM-DD. Someone else may someday have to deal with your shit code, at the very least make the strings sortable FFS.

              Pretty sure no human lived at the Trinity test site or anywhere else in the test sites where weapons were detonated, especially at the moment of detonation. And I’m pretty sure none have since moved onto those sites either. Hence “inhabited”. It’s not like we nuked cities and towns.

          That’s a pretty good description. And most software back then didn’t use nice date utilities, they each had their own inline implementation. So sometimes you had to figure out what they were trying to do in the original code, which was usually written by someone who’s not there anymore. But other times it was the most mundane doing the same fix you already did in 200 other programs.

      The question is, what will happen in 2038 when y2k happens again due to an integer overflow? People are already sounding the alarm but who knows if people will fix all of the systems before it hits.

        It’s already been addressed in Linux - not sure about other OSes. They doubled the size of time data so now you can keep using it until after the heat death of the universe. If you’re around then.

          Obviously new systems are unaffected, the question is how many industrial controllers checking oil pipeline flow levels or whatever were installed before the fix and never updated.

            Being somewhat adjacent to that with my work, there is a good chance anything in a critical area (hopefully fields like utilities, petroleum, areas with enough energy to cause harm) have decently hardened or updated equipment where it either isn’t an issue, will stop reporting tread data correctly, or roll over to date “0” which depending on the platform with industrial equipment tends to be 1970 in my personal experience. That said, there is always the case that it will not be handled correctly and either run away or stop entirely.

      Y2K specifically makes no sense though. Any reasonable way of storing a year would use a binary integer of some length (especially when you want to use as little memory as possible). The same goes for manipulations; they are faster, more memory efficient, and easier to implement in binary. With an 8-bit signed integer counting from 1900, the concerning overflows would occur in 2028, not 2000. A base 10 representation would require at least 8 bits to store a two digit number anyway. There is no advantage to a base 10 representation, and there never has been. For Y2K to have been anything more significant than a text formatting issue, a whole lot of programmers would have had to go out of their way to be really, really bad at their jobs. Also, usage of dates beyond 2000 would have increased gradually for decades leading up to it, so the idea it would be any sort of sudden catastrophe is absurd.

        The issue wasn’t using the dates. The issue was the computer believing it was now on those dates.

        I’m going to assume you aren’t old enough to remember, but the “only two digits to represent the year” issue predates computers. Lots of paper forms just gave two digits. And a lot of early computer work was just digitising paper forms.

        You’re thinking of the problem with modern solutions in mind. Y2K originates from punch cards where everything was stored in characters. To save space only the last 2 digits of the year because back then you didn’t need to store the 19 of year 19xx. The technique of storing data stayed the same for a long time despite technology advancing beyond punch cards. The assumption that it’s always 19xx caused the Y2K bug because once it overflows to 00 the system doesn’t know if it’s 1900 or 2000.

    I literally had this exact exchange with someone last year, when they tried to cast doubt on global warming by comparing it to the ozone. Another person did the same , using acid rain, and I pointed out that the northeast sued the shit out of the Midwest until they cut that shit with the coal fire power plants.

      The Conservative Party led Canadian Government and the Regan-era Republican US Government started working on the US-Canada Air Quality Agreement, which was signed by the George H.W. Bush administration into law in the US (and the Brian Mulroney led Government of Canada).

      That’s right — two Conservative governments identified a problem, listened to their scientists, and enacted a solution to acid rain. And now the problem has virtually disappeared.

      Oh how low Conservatives have fallen on both sides of the border since those days.

    TBH “The whole world agreed on something” narrative doesn’t really reflect what happened.

      The fact is, most companies are fine to let an existing system run rather than replace it with one that has a cheaper consumable thing, provided they can still get that consumable and the cost of replacing that system is high.

      Basically, corps would have kept buying and using CFCs because replacing the refrigeration system is too costly.

      Not only was an alternative found that was cheaper and safer and almost as good (as effective), but scientists and engineers put in the effort to find ways to adapt existing systems to the new working fluid. All for significantly less than replacing the system.

      Not only was a replacement found, but it was made economically viable for widespread deployment in a very short timeframe; not just having a short development time, but also a very short duration to deploy the new solution to an existing system.

      You’re right, that it was cheaper and everything, but most of the time changing the working fluid of a refrigerator/air conditioning unit, will require that the system is replaced. They worked around that. Additionally, you’re correct that it was industry that made the change and pushed it to their clients.

      I just want to make sure we recognise the efforts put in by the scientists and engineers that enabled the rapid switch to non-CFC based cooling systems. It’s still an amazing achievement IMO, and something that required a remarkable amount of cooperation by people who probably don’t cooperate often or at all (and are, in all likelihood, fairly hostile to eachother, most of the time).

      IMO, that’s still one of the best examples of global cooperation that anyone could possibly point to. Rarely do we have a problem where there’s almost universal consensus on the issue and how to fix it. In this case, there was. That level of cooperation among the people of earth is borderline unparalleled; the only other times we cooperated this well that people would know about are usually negotiations done with the barrel of a gun. Namely the world wars. One group said that we’re going to do a thing, another group said nope. It was settled with lives, bullets and bombs, and nearly every person alive was on one side or the other… Except Sweden, I suppose… And maybe smaller countries that didn’t have enough of an army to participate. (I’m sure there’s dozens of reasons, but I’m not a historian)

      Without guns, bombs, or even threats, just a presentation of the facts and a proposal for a solution, everyone just … went along with it.

      To me, that’s unprecedented.

        No.

        The rest of the world’s doing a great job at following through on CFC bans.

        This is entirely on China and China alone. No one is forcing their factories to cut corners and use them. Just the same as plastic rice, gutter oil, poison baby formula, etc.

          I think the argument to be made is that if China is cutting these corners the rest of the world shouldn’t do business with them. By choosing to use a factory that is using CFCs you are increasing demand for them.

        I was thinking of this paper from 2018:

        ACP - Evidence for a continuous decline in lower stratospheric ozone offsetting ozone layer recovery

        Abstract. Ozone forms in the Earth’s atmosphere from the photodissociation of molecular oxygen, primarily in the tropical stratosphere. It is then transported to the extratropics by the Brewer–Dobson circulation (BDC), forming a protective ozone layer around the globe. Human emissions of halogen-containing ozone-depleting substances (hODSs) led to a decline in stratospheric ozone until they were banned by the Montreal Protocol, and since 1998 ozone in the upper stratosphere is rising again, likely the recovery from halogen-induced losses. Total column measurements of ozone between the Earth’s surface and the top of the atmosphere indicate that the ozone layer has stopped declining across the globe, but no clear increase has been observed at latitudes between 60° S and 60° N outside the polar regions (60–90°). Here we report evidence from multiple satellite measurements that ozone in the lower stratosphere between 60° S and 60° N has indeed continued to decline since 1998. We find that, even though upper stratospheric ozone is recovering, the continuing downward trend in the lower stratosphere prevails, resulting in a downward trend in stratospheric column ozone between 60° S and 60° N. We find that total column ozone between 60° S and 60° N appears not to have decreased only because of increases in tropospheric column ozone that compensate for the stratospheric decreases. The reasons for the continued reduction of lower stratospheric ozone are not clear; models do not reproduce these trends, and thus the causes now urgently need to be established.

        and this paper from 2023:

        Potential drivers of the recent large Antarctic ozone holes | Nature Communications

        The past three years (2020–2022) have witnessed the re-emergence of large, long-lived ozone holes over Antarctica. Understanding ozone variability remains of high importance due to the major role Antarctic stratospheric ozone plays in climate variability across the Southern Hemisphere. Climate change has already incited new sources of ozone depletion, and the atmospheric abundance of several chlorofluorocarbons has recently been on the rise. In this work, we take a comprehensive look at the monthly and daily ozone changes at different altitudes and latitudes within the Antarctic ozone hole. Following indications of early-spring recovery, the October middle stratosphere is dominated by continued, significant ozone reduction since 2004, amounting to 26% loss in the core of the ozone hole. We link the declines in mid-spring Antarctic ozone to dynamical changes in mesospheric descent within the polar vortex, highlighting the importance of continued monitoring of the state of the ozone layer.

          Unfortunately there can still be emissions:

          https://www.nature.com/articles/s41586-019-1193-4

          From abstract:

          A recently reported slowdown in the decline of the atmospheric concentration of CFC-11 after 2012, however, suggests that global emissions have increased3,4. A concurrent increase in CFC-11 emissions from eastern Asia contributes to the global emission increase, but the location and magnitude of this regional source are unknown3. Here, using high-frequency atmospheric observations from Gosan, South Korea, and Hateruma, Japan, together with global monitoring data and atmospheric chemical transport model simulations, we investigate regional CFC-11 emissions from eastern Asia. We show that emissions from eastern mainland China are 7.0 ± 3.0 (±1 standard deviation) gigagrams per year higher in 2014–2017 than in 2008–2012, and that the increase in emissions arises primarily around the northeastern provinces of Shandong and Hebei.

      The ozone hole size is influenced by the strength of the polar vortex, the Antarctic temperature, and other things in addition to the concentration of CFC molecules. It’s barely shrunk, but CFCs are so long-lived that was expected - the critical point is it stopped growing over 20 years ago. I believe they expect to start seeing shrinking within the next decade.

    What happened is scientists discovered chlorofluorocarbons were bad for the ozone, countries believed them, the Montreal Protocol was signed, and CFC use fell by 99.7%,l eading to the stabilization of the ozone layer, perhaps the greatest example of global cooperation in history.

                My view is that I would prefer someone younger and with similar ideals as Bernie but in reality, we have a choice between Biden and a man that given the chance, would end liberal’s right to vote forever.

                I feel like people that bitch and complain about Biden do not at all understand the danger we are all in if Trump wins because the vote is split. Republicans do not have a conscience. They are more than happy to band together despite their disagreements if it means that they win. I just wonder why in the fuck anyone would risk that happening again given the decades of harm Trump caused in one term.

                So am I happy about voting for Biden? No not really. It bothers the fuck out of me that Israel has the support it does. But the reality is that Trump and the modern republican party are about [] that close to reinacting the night of broken glass and Id rather that not happen.

                  I don’t think you understand the point of view people critisizing Biden. Democrats are the ones that put Trump in power, just so they can have an easier elections and don’t have to place more popular candidates to run against them. Voting for Biden is simply accepting defeat, that their plan worked and that they can do absolutely anything and you will support them because they will also support a worse candidate on the other side at the same time. It is not looking at the big picture, long term. In the future they can get someone like Trump to be a Democrat candidate and support someone even worse on the Republican side and you will have to vote for them under exactly the same situation. Democrats have a candidate that literarlly funds a genocide and we would think that once that line is crossed people would simply say that is enough, but apparently even Hitler would be elected in US elections as long as he places someone worse as prime candidate of another party.

      Problem with that is that in comparison the alternative to CFC was not that more expensive and then a cheaper one was invented shortly after.

          It’s not so simple. They’re cheaper than building non renewable, but are they cheaper than keeping the current plants running? Also, energy consumption keeps growing, and in many places, new generating plants using renewables usually only take care of the growth, and doesn’t allow for room to take older plants out of operations. If we don’t make huge efforts to reduce our energy consumption, I doubt we’re going to get rid of non renewables so soon…
