        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.

            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.

            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.

          AfaIk that’s not entirely true, e.g. Debian is changing the system time from 32 bit integer to 64 bit. Thus I assume other distros do this as well. However, this does not help for industrial or IOT devices running deprecated Unix / Linux derivatives.

          It had no payload on any of its flights. Rockets that have enough time/money put into development to have a reasonable expectation of working on the first try (and don’t have such an ambitious design) normally launch with a payload on their first flight. Sometimes, even those fail on the first few flights. Having the first few of a new rocket design fail before reliability is achieved is common (ex: Astra) and SpaceX’s other rocket, the Falcon 9, is known as the most reliable rocket, I even suspect it achieves landings more often lately than most others do launches.

          Starship’s last launch went decently well, reaching orbit (which is as far as most rockets go!) but failing during reentry. It is also supposed to be the rocket with the largest payload capacity to low earth orbit, with 100-150 tons when reused and likely 200-300 when expended.

          Starship, as it is right now, is already a better rocket than SLS. It can already carry more mass and be cheaper (even fully expended) than the SLS’s 4 billion cost per launch.

          It will get better. Falcon 9 didn’t land the first time either, but now it has successfully landed more consecutive times than any other rocket has flown.

          There’s nothing wrong with saying this is a test. This is only a test, and we don’t expect it to be perfect yet. Each time they learn from the data. And SpaceX hasn’t repeated the same mistake twice.

          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.

      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.

        You do realize that “counting from 1900” meant storing only the last two digits and just hardcoding the programs to print"19" in front of it in those days? At best, an overflow would lead to 19100, 1910 or 1900, depending on the print routines.

        Was there ever really a threat to begin with? The whole thing sounds like Jewish space lasers to me.

          It was a massive threat as it would break banking records and aircraft flight paths. Those industries spent millions to fix the problem. In 14 years(2038) we’ll have a similar problem with all 32bit computers breaking if they haven’t had firmware updates to store UTC time as a 64bit number composed of two 32bit numbers. Lots of medical, industrial, and government equipment will need to either be patched or replaced.

          There wasn’t much of a real “threat”, in that planes wouldn’t fall out of the sky. but banking systems would probably get quite confused, and potentially lead to people being unable to access money easily until it got fixed.

    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.

        I’d argue that while we are much more diligent than other countries, and regulations are much stronger. The average person doesn’t pay nearly enough attention, and the fact the UV index isn’t required to be mentioned on weather reports, or as prominently or more prominently than the temperature, is a big oversight in my opinion.

        I check the UV every time I go outside (other than when it’s died down over winter), just as you’d check the temperature, and I think it’s wild barely anyone else does.

      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.

      For climate change you basically can double our energy costs and therefore double the cost of almost everything.

          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…

    This has since been determined to have tack on benefits in the fight against the climate crisis as well, it’s halved the potential growth in global average temperatures by 2100, which cannot be overstated in just how fantastic that is.

    We went from everyone being baked alive and having 20 kinds of skin cancer to boot to merely dealing with catastrophic climate change and society changing people migrations the likes of which haven’t been documented since the successive eras of steppe invasions into Europe, China, India, and the Middle East.

      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.

        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 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.

                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.

      Matt Walsh is literally the dumbest person on the planet. Most of the people involved with The Daily Wire are cynical little freaks playing a part, Walsh is just a moron.
