| Climate Central has a model that can show how much more intense hurricanes are based on how much warmer the ocean is. This is an advance for attribution science, which aims to show how much of a natural disaster is attributed to climate change. In the future I expect a party, perhaps an insurance firm, or reinsurance firm sue oil companies for their role in accelerating climate change to pay for the cost of natural disasters. |

Why make something legal and build your entire society around it and then turn around and retroactively blame them for providing legal goods? Seems insane to me. | | |
| ▲ | js8 7 months ago | parent | next [-] | | It's not what happened, though. Fossil fuel companies had studies about the impact of AGW since 60s, and yet decided to fund climate change denial. That's criminal. | | |
| ▲ | brookst 7 months ago | parent [-] | | But here we are talking about this recent advance in showing cause/effect. Are you saying the fossil fuel companies had this knowledge 60 years ago and scientists are just learning it now? | | |
| ▲ | margalabargala 7 months ago | parent | next [-] | | Fossil fuel companies, and scientists, had the knowledge that CO2 emissions from fossil fuels would warm the earth 60 years ago. Here we are now talking about a specific example of someone doing some math and writing an article about it. This is not a "recent advance", it's a retrospective based on warming that has already happened. Someone 60 years ago could have (and did!) predict "warming will cause stronger hurricanes, and here's about how much stronger they might get". This article is "here are some hurricanes that happened recently, and here is specifically how much stronger they were than they would have been, due to the warming over the last 60 years" | |

| ▲ | bongodongobob 7 months ago | parent | prev [-] | | No. Fossil fuel companies and scientist knew the effects. What is new is attributing how much of the storms power is due to climate change. It's a new metric essentially. |

| ▲ | JadeNB 7 months ago | parent [-] | | > To counteract the opposite incentive - "we learned there's a terrible side effect of what we're doing, the obvious choice is to bury that info and cover it up" by making you liable once others catch on. Doesn't the presence of legal penalties for an action make it even more desirable (for the perpetrator, from a purely practical point of view) to bury information about those actions and cover them up? |

| ▲ | richardw 7 months ago | parent | prev [-] | | Because they’ve gone to great lengths to influence what is legal. Humanity should have more than a “we told you so”. It’ll also reduce more of this BS in future, when people act against all our interests with no repercussions, sailing super yachts on the ever-expanding waterline. |

| ▲ | burkaman 7 months ago | parent | prev | next [-] | | Several US states have already done that, Maine just did a couple days ago: https://www.maine.gov/ag/news/article.shtml?id=13129752 | |
| ▲ | SoftTalker 7 months ago | parent | prev | next [-] | | It's not like we all didn't want and buy the oil. | | |
| ▲ | burkaman 7 months ago | parent | next [-] | | We didn't all launch an ongoing decades-long campaign of lies about what the consequences will be though. | | |
| ▲ | anonym29 7 months ago | parent [-] | | Right, we just blindly trusted the first things we heard on the subject, and everyone knows that's rational because humans never lie. Remember: as long as you trust your government, trust the corporations, trust all the information you hear, especially from large and well-known institutions, you'll always be fine. Never slow down, never stop to think, just keep buying, keep consuming, keep tuning into the same media sources, and NEVER EVER dare to question social consensus! | | |
| ▲ | burkaman 7 months ago | parent | next [-] | | I get the sarcasm but I don't really understand who you're mocking. I guess people who foolishly followed the herd and bought a gas car in the 80s instead of doing their own research and inventing an electric one. | |
| ▲ | twojacobtwo 7 months ago | parent | prev [-] | | No one has time to verify/double check literally everything they're told. And if they did, they wouldn't have the time to learn everything that one would need to know to verify everything. It's impossible. Therefore, some level of trust is necessary: moreso for those who have less time/opportunity to learn and verify. While I understand the sentiment, blaming ~everyone~ provides no value here, while blaming the institutions who actively misled the world might. |

| ▲ | CalRobert 7 months ago | parent | prev | next [-] | | I didn’t want to. But my home was a mile+ away from anything and a terrible place to walk with no public transportation in large part thanks to the actions of oil and car companies | | |
| ▲ | xyzelement 7 months ago | parent [-] | | I couldn't help but notice in your profile that you literally created a site to find homes based on attributes that are important to you, with the first example being "transport." | | |
| ▲ | CalRobert 7 months ago | parent | next [-] | | Indeed! I grew up in a car dependent place and wanted to find one where it was easier to live without being so reliant on one. Same reason I moved to Europe, though Ireland was disappointing in this regard | |
| ▲ | twojacobtwo 7 months ago | parent | prev [-] | | Sounds like personal experience -> project motivation. |
|
| |
| ▲ | taneq 7 months ago | parent | prev [-] | | We should invent some kind of term that makes it sound like everyone had all the info since the 70s and so everyone's equally to blame. I know, let's say "carbon footprint" and make it sound like every single human has been deliberately stomping all over the environment. | | |
| ▲ | openrisk 7 months ago | parent [-] | | Thats quite cynical, but more importantly, by not accepting as legitimate the so-called "consumer responsibility" angle you are missing half of the equation. Already in this forum there more than enough people that will viciously defend their right to consume whatever they fancy with "their hard-earned money" and would cry "tyranny" if you suggest there is a limit after which their lifestyle becomes a danger to others. The equation gets even more muddied if you also consider the responsibility of individuals as labor providers to the corporate entities that are responsible for environmental degradation. Again, people "got to pay the bills" etc. Sure, there are bad people out there, prime suspects, clear villains. But its mostly bad systems. | | |
| ▲ | ceejayoz 7 months ago | parent [-] | | The fallacy of the “consumer responsibility” argument is the same as the problem with “ideal communism” - it requires pretending humans aren’t humans. | | |
| ▲ | baq 7 months ago | parent | next [-] | | humans respond as expected to high taxes on things which other humans decide should be taxed. in this case, burning oil and coal should be taxed so other sources of energy are incentivized. the point you highlight is 'your tax is my opportunity' for those who don't care, to paraphrase a certain wealthy man. | |
| ▲ | barbazoo 7 months ago | parent | prev [-] | | I don't get it. Communism is a system, consumer responsibility is individual. Every individual changing their behavior changes the outcome. | | |
| ▲ | ceejayoz 7 months ago | parent | next [-] | | Both require people to care enough about others they’ll never meet enough to significantly self-sacrifice to be successful. I can cut my carbon footprint to the bone, and my neighbor will run their two-stroke leaf blower all day because they like the noise it makes. | | |
| ▲ | openrisk 7 months ago | parent | next [-] | | I am not sure you are familiar with what the term consumer responsibility means in this context. It doesnt mean to rely on consumer's "good hearts" and conscience. Its a mechanism to attribute impact to final consumption, so that the costs of that impact are also priced to influence these consumers. So your neighbor would somehow pay for their mindless blowing (rather than the manufacturer or the fuel provider). The comment to which I responded implied that this is unfair, that the corporate beneficiaries / polluters should "pay". | |
| ▲ | barbazoo 7 months ago | parent | prev [-] | | Totally. > I can cut my carbon footprint to the bone, and my neighbor will run their two-stroke leaf blower all day because they like the noise it makes. Personally I reduced our currently measurable monthly CO2 emissions from ~350kg/month to ~15kg/month. They need a lot of (gas powered) leaf blowers to offset that. If thousands or millions of people do it, it'll make a difference. I'm aware of course that not everyone is in the financial position to do what we did. For a lot of people though it's a choice they could make if they're open to changing their lifestyle a little bit. (I'm not saying our emissions are down to 15kg/month, but that's based on what I can currently measure, transportation, LNG, electricity, etc. Likely they are much higher of course but I gotta start somewhere) | | |
| ▲ | JadeNB 7 months ago | parent [-] | | > Personally I reduced our currently measurable monthly CO2 emissions from ~350kg/month to ~15kg/month. How? | | |
| ▲ | barbazoo 7 months ago | parent [-] | | By switching to low carbon fuels mostly, e.g. from LNG to RNG (renewable natural gas) and from gas to electricity by getting a (used) EV. |

| ▲ | stouset 7 months ago | parent | prev [-] | | Individuals are capable of altering their behavior. Groups behave in accordance with incentive structures. Hoping for and/or expecting societal change through mass application of willpower is wishful thinking. | | |
| ▲ | lotsofpulp 7 months ago | parent [-] | | That sounds like an argument against democracy. | | |
| ▲ | almostnormal 7 months ago | parent | next [-] | | It's not difficult to argue against democracy, but it's very difficult to find an alternative that isn't much worse. | |
| ▲ | stouset 7 months ago | parent | prev [-] | | I genuinely don’t follow. | | |
| ▲ | lotsofpulp 7 months ago | parent [-] | | > Hoping for and/or expecting societal change through mass application of willpower This sounds like the same mechanism for democracy, educating a broad populace and hoping they make the right (best?) choices. | | |
| ▲ | stouset 7 months ago | parent [-] | | Educating a person is materially different from getting them to act against their incentives. Doing so with a population is even more so. The average American is overweight and doesn’t exercise. They are almost certainly aware they need to reduce their calorie intake and spend at least a couple of hours a week engaging in physical activity. Knowing you ought to change you behavior and actually doing it are completely different issues. I actually happen to think that both are basically losing battles these days, but the underlying reasons aren’t the same. |

| The empirical data is that we don't have more hurricane (in total or per category) per decade now than we did 150 years ago [1]. So if climate change (which is real, to be clear) is intensifying hurricane, shouldn't that be reflected in the data? Likewise, when Helene hit North Carolina, this too was attributed to climate change except the exact same thing happened a century ago [2]. When we talk about the impact of hurricanes on infrastructure, people and buildings, we forget that there are an awful lot more people now than there was a century ago. 100 years ago, the population of Florida was less than a million. Calling every storm a once in a century storm or saying how once a century events now happen every year (you'll hear both of these claims often) does nothing but discredit climate change. Move a normal distribution half a standard deviation left or right and you have real impact but it will take you a lot of data points to figure out that's really happened. Extreme outliers in either case will tell you, quite literally, nothing. [1]: https://www.nhc.noaa.gov/pastdec.shtml [2]: https://www.usatoday.com/story/graphics/2024/10/07/hurricane... |

Isn't it the other way? If climate change makes storms more intense, then "(previously) once-a-century storm happening more often than once a century" is precisely what you would expect to see. I agree that there are too many breathless headlines and not enough scientific rigor, but that happens with any topic, not just climate change. * Also, nothing can really "discredit climate change" in the same sense nothing can discredit covid-19 or the war in Ukraine. It's happening, we all know it's happening, the most we could argue about is how it would impact the world. | |

| > the potential damages caused by a storm increase exponentially—by a power of eight—with increases in wind speed As any CS undergraduate will be able to point out, this is not exponential, it's polynomial. Exponential means that damage ∝ a^speed A good CS undergraduate will be able to point out that this doesn't matter, as the constants involved may well be more important. |

| Glad we've finally figured out how to isolate the impacts of a single variable on a massive and incredibly complex system without even enumerating all of those other variables. The Science (tm) is so cool! |
| |
| ▲ | seadan83 7 months ago | parent | next [-] | | > without even You're assuming that the other variables were not enumerated, to which it seems likely you would be very wrong. The difference here is, given all the variables - what happens when you turn the sea surface temperature dial up? That DOES take into account the other variables. Previously, the answer was "no clue, the interactions between the interdependent variables are too complex to come to any possible conclusion." | | |
| ▲ | gwervc 7 months ago | parent [-] | | In a model. Which is the "in mice" equivalent in climate science. But heh, I like a new version of Sim City as much as anyone else. | | |
| ▲ | biblioman 7 months ago | parent [-] | | By "'in mice' equivalent", do you mean "a useful way to make statements about things that can't be directly measured"? Assuming you don't mean that, that's not a gotcha. Practically all of science is "in a model". We can't observe an alternative universe where DNA doesn't mutate, but that doesn't disprove evolution. | | |
| ▲ | anonym29 7 months ago | parent [-] | | I'm not saying we shouldn't observe and try to learn more with an open, curious, and inquisitive mind. I'm saying we shouldn't be making definitive high-confidence assertions along the lines of "there's mathematical proof that anthropogenic climate change is the factor that causes X more deaths in Y storm". Because this isn't a matter of 2+2=4. There are more variables at play here than the combination of our intelligence and our technology allows us to accurately model. If what we brought to the table was good enough, we could consistently and accurately predict the weather a week out. Also, I want to be completely clear that my counterpoints here are not a refutation that human activity is a contributing factor to climate change (it absolutely is a factor), or that climate change isn't happening (the climate is absolutely changing). I'm simply suggesting is that there are more factors besides human activity that are also contributing factors. We also don't know what all of these factors are yet, and I'm not aware of any techniques that allow you to isolate the impact of any individual factor in a complex system without knowing even how many other factors there are to control for, let alone what the values of those unknown factors are. | | |
| ▲ | seadan83 7 months ago | parent [-] | | At this juncture, I'm sorry that I'm having trouble understanding the exact counter point. > Also, I want to be completely clear that my counterpoints ... I appreciate these clarifications, thank you. To paraphrase the article a bit, storm models basically are looking back at storms and are comparing storms with differing temperatures. We can then use this to understand what difference a couple degrees makes, this difference is due to climate change (which has raised temps by a couple degrees). > If what we brought to the table was good enough, we could consistently and accurately predict the weather a week out. I don't think so - this sounds like shifting the goalposts. Looking at past events is much better for controlling comparable variables compared to predicting future events. Predicting future events is a whole different ballgame vs saying "had Y happened, it would have looked like X, which did Z". Which is also to say: the variables of these two storms line up, except for the temperature variable - and this was the difference in windspeed between the two storms. Seemingly the models are relatively predictive over the dataset they have, and since we are looking back at existing events - it does seem more solid for analysis compared to predicting future storms. The full methodology is not stated beyond this. So, our criticism of accounting for variables or neglecting variables is from a position of ignorance. FWIW - This is the pertinent section from the article below: > “Climate models and observations are both showing us that, in a world without climate change, temperatures would be somewhere between 2 to 3 degrees Fahrenheit cooler,” Gilford said. Because the intensity of a hurricane is determined foremost by the temperature of the seas over which it passes, Gilford and team used the pre-warming sea surface temperatures to determine the maximum wind speeds that any particular hurricane theoretically would have reached without climate change. From there, they used statistical relationships gleaned from past hurricane seasons to estimate what the wind speeds might have been without warming. They could then compare these numbers against the speeds that were actually recorded to determine how much climate change likely ramped up the intensity. |
