[flagged] Europe's deadly floods are glimpse of future climate (bbc.com)

What's up with so many Hacker News commenters coming out of the woodwork when headlines blame climate change to challenge it?

Just a glimpse of the article shows there's some research behind making the point of the headline, still people feel the need to comment on their feelings to deny it possibly could be due to climate change.

Per the article:

> The World Weather Attribution (WWA) group said one recent four-day period was the rainiest ever recorded in central Europe - an intensity made twice as likely by climate change.

> The kind of rainfall unleashed by Boris is thankfully still rare – expected to occur about once every 100-300 years in today’s climate, which has warmed by about 1.3C due to greenhouse gas emissions.

> But if warming reaches 2C, similar episodes will become an extra 5% more intense and 50% more frequent, the WWA warned.

> Without more ambitious climate action, global warming is expected to reach around 3C by the end of the century.

> “This is definitely what we will see much more of in the future,” said Friederike Otto, senior lecturer in climate science at Imperial College London and co-author of the WWA study.

There's a study, BBC is reporting on it and some people feel the need to challenge it even though probably know nothing of climate science?

Is science denialism reaching even folks here? What do you get out of this behaviour?


I've noticed that myself and attributed it to the site having a large percentage of U.S. readers. It's annoying when there's scientific studies and then a lot of the comments take a particular political stance about the topic.

The submission itself usually disappears from the front page very quickly too which might be because of the low quality comments.


FWIW, all those posts are coming from IP addresses that map to the EU. I think many (most?) are by the same person.

About 50% of HN users were in the US, last time I looked at this, but it was years ago.


Interesting that they are linked to a limited number of people - that does imply astroturfing to my mind.

I'm glad to see that I'm wrong about it being a U.S.-centric site. My default assumption is that a lot of websites are heavily U.S. biased and a 50% U.S. vs the rest of the world sounds like a good mix to me. (I'm in the UK).


So basically astroturfing? Does this type of activity automatically get flagged? I wish there were a way for us regular users to be able to detect this. Otherwise, we end up with these discussions where people conclude that something is, say, a widespread mentality in the U.S, or a "Silicon Valley thing", when in reality it could be a small number of bad actors.

It's quite difficult to assess what's happening on HN from the outside (I know, I've tried).

It's both bad form and against guidelines to make accusations.

But you can ping mods if you suspect some sort of promotion/demotion ring, sockpuppets, etc. I'd emailed dang about an hour ago on this thread. My regret is not having done so earlier.


> a lot of the comments take a particular political stance about the topic.

And oftentimes, these political stances are US-centric and don't make sense to anyone else, e.g. you might have an article about the efficacy of masks and then you'll read a dozen comments saying that "Fauci lied to us", which is completely irrelevant to anyone not living in the US (if you really wanted to generalise it, you'd have to claim that politicians in most countries lied to their people which IMHO is a much harder sell, but whatever).


Whilst much of Europe is well past climate denialism, with the exception of the petro-fascist state of Russia, there's still an active English-speaking denialist community in the UK, less so in politics than in the largely right-wing / conservative press, with such people as Matt Ridley leading that brigade.

I spend a great deal of time reading and listening to news from across Europe, and the degree to which climate, degrowth, and energy transition are treated as mainstream topics is far ahead of the US, another petro-state.

(Notably, Norway doesn't seem to have followed the lead of other petro-states in climate denial that I'm aware, though its own oil-wealth legacy is distinctive on several grounds.)


> Is science denialism reaching even folks here?

Reaching from where? You are responding to the source of it - emotionally charged language in journalistic reporting.


It’s the Silicon Valley wannabe intellectualism that has somehow allied itself with contrarianism.

They just reflexively think the consensus view is wrong because daddy Thiel said you can make big money that way.

“The Contrarians”, of course, is its own silly tribe of lemmings that produces its opinions from its identity first and foremost.


> Silicon Valley wannabe intellectualism

I've noticed the fringe hot takes tends to occur around this time of day on HN, which is 5am in SV (some of us wake up very early to run/bike without getting run over, as well as answer EMEA emails).

Most users at this time of day are European (who tend to be German, Eastern European, and British ime) and some East Coasters.

Mainstream HN doesn't kick in until 4-5 hours from now.


I would say that Europeans are entitled to describe the actual weather in Europe as opposed to the SV narrative of it.

I have no idea what GP was trying to say with his "it's mostly European users" comment, but as a European who does worry about climate change, I don't think that climate change denialism is somehow less extreme in the US than in Europe.

> "it's mostly European users" comment

I meant it isn't West Coast users on HN at this time of day. It's mostly European users before transitioning to East Coast users

It's an international forum, and depending on the time of day, HN's tone changes significantly


I agree that the tone shifts depending on the user base, but your comment appears to imply that there are more fringe takes when European users are online. I don't think that's the case and I also wouldn't know why Europeans are somehow more fringe (we do tend to have different cultural expectations, but "climate change denialism" is, I think, not one of them).

I didn't mean that Europeans make more fringe takes. I think the rate is consistent with American users.

IMO, the difference is there is less usage during peak EMEA hours, which makes fringe takes more prominent and visible, but by the time West Coast is using HN, that is peak overlap time for all users of HN globally.


ok fair enough, thanks for explaining.

HN audience is both reflexively contrarian (will argue with any article on any subject), and also surprisingly rightwing (exposed to climate change denialists).

There is a surprisingly vocal and toxic community that are fringe members on both sides of the aisle on HN.

Hypothetically a good thing, but in action it tends to derail most conversations.

The whole COVID Pandemic, the 2020 election, (edit: and the shutdown of SlateStarCodex) definetly brought a lot of nuts out of the woodwork, and they never left.

Edit: Here's an example below. It's one account that I've had significant arguments with before. In addition, it's also a "new" (post-2021) account, ime all of whom don't tend to provide the level of discourse comparable to earlier HN users (yes, I recognize the irony as a combative newish throwaway)

There was a large increase in HN usewebase around that time when the SlateStarCodex forum shut down.


> The whole COVID Pandemic and the 2020 election definetly brought a lot of nuts out of the woodwork, and they never left.

HN was downright insufferable during the pandemic, it really made me think about leaving. Thankfully, nowadays the "bad" topics (mostly politically very polarised ones) tend to be fewer and can more easily be avoided.


> it really made me think about leaving

Same here, except it just made me combative on HN.

I'm waiting for the day dang blocks my account for a violation AND deletes all my posts, because YC won't honor a CCPA request without proof of identity, and I'm a bit too close for comfort with the YC community so I do not want to furnish that to him or YC.

If there was a way to filter accounts created after 2021, or with a polarity score, I'd be happy staying on here, but at this point it's a form of social media addiction due to the dopamine rush of the occasionally level headed conversation and debate.


fwiw, there's https://news.ycombinator.com/classic which is the "Frontpage as voted by ancient accounts", so dang has some notion of that.

Not fringe at all. Watch the all-in podcast on YouTube, who just had Mearsheimer and Jeffrey Sachs as guests, with a large and enthusiastic live audience.

Speaking of which, Calacanis just had Covid. Are you still wearing a mask? If not, why not? Covid is still present but Biden declared it over in March 2022 and then it was suddenly officially over for all followers.


You created an account just to argue with me?

Use your real account.


I sympathise, having had someone hunt down my (now old) Wordpress blog and post an angry and barely coherent rant there due to something pro-mask that I wrote here:

https://benwheatley.github.io/blog/2021/06/14-21.59.37.html

And yes, I still wear masks on public transport. Except when I clear my pockets and forget to replace them.


Who were "the nuts" during the COVID pandemic?

The ones wishing unemployment, imprisonment, and death upon the people who didn't want to get the vaccine? The ones who insisted on forcing kids to were masks? Or the ones who silenced scientists who held differing view points from the mainstream narrative or challenged the efficacy of masks? Or the ones who were saying Ivermectin was for horses? Or the ones who said if you get the vaccine you won't catch or spread COVID?


> Ivermectin was for horses

It's for worms. If you have a persistent infection of parasitic horses, it's probably not going to do much good.


What they're getting confused with is that as the craze hit and Ivermectin supplies ran low, some people were buying it from veterinary supply stores in formulations meant for horses.

People were, quite rightly, saying that taking medicine formulations meant for horses was a bad idea, given the potentially non-human-friendly additional ingredients and the difficulty in keeping within safe dosages.


> surprisingly rightwing

If I try to put it into (very reductive) descriptive terms, I might say that the "left" puts more emphasis on the fact that people are victims of circumstances, while the "right" puts more emphasis on the idea that everyone's the architect of their own destiny.

Both of these perspectives are correct to some extent - you could argue about it endlessly, from a philosophical point of view. But it's maybe also not that surprising that people who are (to some extent) aligned with a hacker ethos and have had success in life by working on hard problems would find that second point of view much more enticing - after all, it's much more satisfying to think that your success is due to your own virtue than due to your luck (when it the end, it may very well be both).

There are of course also sometimes elements of hypocrisy in it, in situations where HN users feel they have less agency. While there is a strong (though definitely not unchallenged) sentiment among a segment of the userbase that companies should do whatever they want when it comes to their products and business practices, you very rarely see that same sentiment applied when it comes to things that affect developers in their daily work, such as home office, meetings, Scrum, etc.


Also a surprisingly large number of them are libertarians, whose view is that government can never do anything right and if anybody claims a government intervention (or a concerted society-level effort) is necessary then they are lying.

Climate change is, almost by definition, something that cannot be solved at individual level. It must be tackled at the society level. Which makes it a lie in their worldview.

Don't ask me, I could never understand the libertarian position.


I've put some effort into doing so.

Much of the mainstream right-libertarian rhetoric seems to trace most directly to Murray Rothbard and to a lesser degree Robert Nozick (though he distanced himself from that somewhat later in life), with strong supporting roles from Milton Friedman, F.A. Hayek, von Mises, and others. The institutional support is strongly tied to the Kochs, the Cato Institute, and a large group of aligned propaganda mills through the Atlas Network, comprised of 500+ partners in 100+ countries, to quote the network itself. The greatest number are in the US (181) and Europe (157), with a disproportionate number in the English-language speaking Canada (11) and Australia (10):

<https://www.sourcewatch.org/index.php?title=Atlas_Network>

<https://www.atlasnetwork.org/partners>

Somewhat interestingly, few of the RLs I've encountered seem even aware of this legacy, with many appearing to think that they'd reached an identical set of conclusions (and rhetoric) through their own self-directed free thinking...

The Atlas Network itself is strongly tied to the Mont Pelerin Society. Philip Mirowski and Dieter Plehwe edited an excellent history of that movement, The Raod from Mont Pelerin (2015):

<https://www.hup.harvard.edu/books/9780674088344>


I've had both views, and still think that the first is fairly accurate.

I'm no longer so certain that HN is strongly right-wing. There are definitely right-wing members, and so long as they act within HN's guidelines that's possibly a Good Thing in the spirit of airing a range of views across the spectrum (not in its more recent psychiatric sense), which would include debunking fallacious and calling out of actively dangerous views.

From what I've been able to directly observe,[1] both left- and right-wing political harrangues and advocacy seem to fare poorly. Right-wing think tanks, Reason being the notable exception, are rarely linked to HN. Most news stories come from largely centrist sources, with the NY Times and WSJ both being amongst the most frequently hitting the front page. (Both have seen a sharp drop in front-page appearances as their respective paywalls have tightened, NYT falling to < 25% of its prior frequency, a point I'd like to see explored in detail as journalism's fight for survival continues.)

Ideological talking points / memes tend to be low-effort, regurgitations, and easy to post to threads, especially early. And I suspect, with some basis in media theory, that this tends to favour the populist right.[2] This post itself has seen a sharp reshuffling (which is continuing as I make some later comments to it, on that specific topic) as votes and flags take effect. The previously top-ranked comment is now (quite rightfully IMO) flagged: <https://news.ycombinator.com/item?id=41646319>), along with numerous others.

Unfortunately overall substantive discussion and story placement on the front page have both suffered as a consequence (points I've made in email to dang).

2. See generally the Frankfurt School's work. Dwight MacDonald's "A THeory of Mass Culture" (1953) develops the idea <https://is.muni.cz/el/1421/jaro2008/ESB032/um/5136660/MacDon...>, as does Umberto Eco's "Ur Fascism" (1995) <https://web.archive.org/web/20240000000000*/https://www.nybo...>.


There are topics HN has extreme difficulty in discussing rationally, one of my prime disappointments with the site.[1]

There are also clues in HN's moderation, in guidelines, by members, by mods, and by automated processes, which may give some hints as to how to best address this.

HN guidelines include a number of elements which might be used against disinformation / denialist comments, specifically:

- Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

- Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.

- Please don't post shallow dismissals.

But most particularly these two:

- Eschew flamebait. Avoid generic tangents. Omit internet tropes.

Virtually all denialist points are in fact generic tangents and Internet tropes. That they're also by all appearances based on shallow (if any) reading of the specific article in question is all the more damning.

- Please don't use Hacker News for political or ideological battle. That tramples curiosity.

I've discussed both these two points in emails with dang, and suspect that applying them has significant traction.

The out-of-the-woodwork aspect of this suggests that accounts are engaged in ideological battle. I'd watched this post as, early in the US/SV day, multiple shallow takes and tropes (most though not all now strongly downvoted or flagged) appeared on this topic. Long before any substative and science-backed discussion appeared. The one apparently substantive denialist take was from a twenty-year-old study which, for some reason, omits much of the past twenty-years alarming increase in flood frequency and severity (now flagged comment: <https://news.ycombinator.com/item?id=41646319>). I'm seeing both "green" (recently-created) and some rather familiar accounts expressing denialist views. And yes, I've been tracking some of the less-substantive / useful contributors to HN for a while now. It's a small set but they can effectively steer discussion, especially if posting early to a thread.

Member flags and voting contribute somewhat to post and discussion quality, and here again on contentious topics what often seems to be occurring is a great deal of strongly motivated voting and flagging activity. I may partake of that myself, though I believe, with some basis in underlying science and facts, that my own actions are strongly justified. (I am not in the denialist camp, should that not have been sufficiently clear already.) That's something of a given, though mods can take actions on flags to some extent.

Mods will wade in sometimes, though for the most part their time and attention are quite limited. They may be summoned by email to hn@ycombinator.com. Responses generally occur, though I'm noting these are often many hours delayed of late.

Automated moderation applies to specific sites (most general news sites are modestly penalised by HN, they remain among its most frequent and highly-voted sites), and more specifically for this discussion, the "flamewar detector". This is a heuristic that posts with > ~40 votes with a comments:votes ration > 1 (<https://news.ycombinator.com/item?id=36926236>). I've suggested "spiciness" as an alternate name for this. Whilst it does work pretty well in many cases, it seems to unfairly penalise precisely the highly-contentious threads which HN already has difficulty in discussing. I'd argue that that characteristic cuts against HN's prime directive, of stimulating intellectual curiosity (<https://news.ycombinator.com/item?id=26998308>) and [T]o make thoughtful comments. Thoughtful in both senses: civil and substantial" (<https://news.ycombinator.com/newswelcome.html>).

If anyone could suggest ways of distinguishing truly flamey threads from those which are substantive-but-spicey, I'd love to hear them, and I suspect mods might as well. What's most frustrating is that the trolls, flames, disinfo warriors, etc., all manage to frustrate substantive discussion. I find it's best not to engage significantly with them, other than to provide a single succinct rebuttal, e.g., pointing out that an article claiming no increase in high-water events dates back two decades.

I also suspect that dang gets frustrated with the disinfo aspect as well.[2]

One of the best ways to counter thread-derailment, which submitters can undertake, is to post a thoughtful, considered, comment which highlights a key aspect of an article. HN is reactive, and such comments tend to get upvoted and, though drawing critical "no, but" responses, also typically draw "yes, and" responses which further emphasize key points, facts, arguments, and related materials.

Posting such a comment even if apparently after a thread has derailed can also perform surprisingly well. I've adopted this practice to some success. Both are far more effective than complaining about behaviour.

Oh, and email the mods. I'll be doing so after posting this comment, linking it as my broader complaint. I do believe there's some opportunity for improvement here.

> If anyone could suggest ways of distinguishing truly flamey threads from those which are substantive-but-spicey, I'd love to hear them

Taking threads that trigger the flamewar detector (simple comments vs points comparison) and then running them (either individual comments or the comments as a whole) through an LLM to score them for flamebait seems obvious so my question is why didn't that go anywhere. If you didn't want to use new technology, you could still just build a classifier based on the usernames involved. It wouldn't have to be perfectly accurate, just enough to flag something for manual review.


That's one thought I'd had.

There's a simpler heuristic which was developed at Microsoft back in the early aughts, based on Usenet, which simply looked at thread topology to make inferences about the type of exchange.

I'm pretty sure that was Marc Smith (the name was a very common one, that or Jones was in my memory), see:

"You Are Who You Talk To: Detecting Roles in Usenet Newsgroups" (~2005?)

<https://www.microsoft.com/en-us/research/wp-content/uploads/...> (PDF)

(Date based on citations and recent data (2004) mentioned in article. Why aren't academic articles internally dated?)

NB: That's one paper I've found, not necessarily the most applicable, though it points in the right direction. I'll update (edit or reply) if I find something more appropriate.


> Just a glimpse of the article shows there's some research behind making the point of the headline, still people feel the need to comment on their feelings to deny it possibly could be due to climate change.

because "due to" is simplistic when we are dealing with multiple factors.

heavier rain might be more common due to climate change, but it causes a lot more flooding than it otherwise would because of the blocking of drainage etc.

> today’s climate, which has warmed by about 1.3C

Warmed by 1.3°C against what benchmark?


I guess retreating from denial to nit-picking is at least some progress.

Any disagreement with what you want to think is "denialism", any undeniable facts you do not like are "nitpicking"

The "deniers" are clearly right about one thing - rational argument is not welcome.


Some areas may become inappropriate(lethal...) for housing. A lot of people may have to be moved, not to mention the amount of new housing to build.

Some states should have a lot of spare housing and keep it available... because because once they need it in a kind of urgent matter...


Or housing can be modified to tolerate the occasional flood. Lives can be saved through better prediction and quick evacuation. The economic impact of regular repair and recovery may be less than abandoning such areas.

It is insanely difficult to construct general-purpose housing which can withstand metres-deep water flowing at high rates. All the more so where flooding is combined with landslides, debris flows, washouts, sinkholes, and the like.

Prediction and advanced warning helps considerably, but is itself problematic where storms intensify rapidly and threaten a huge area. This has been the case for several recent European flood events, most notably in the Ahr valley in 2021:

<https://www.theguardian.com/world/2022/jul/13/floods-then-an...>

As I write, Hurricane Helene, a tropical depression just a day ago, is intensifying in the Gulf of Mexico and threatening landfall on a region which spans from Alabama to the Florida peninsula (though the panhandle / Big Bend region seems most likely). The storm is anticipated to further intensify to major hurricane status (category 3 or higher, winds from 178 -- 209 km/h, 111--130 mph, or higher) before making landfall tomorrow evening local time.

That's a huge area which faces possible evacuation. The more so as despite the localised nature of the hurricane eye, Helene's total diameter is huge, and tropical storm or better wind speeds are forecast from Louisiana to South Carolina, and encompas all Florida and Georgia, along with nearly all of Alaabama and South Carolina, as well as parts of Mississippi, Tennessee, and North Carolina.

The one saving grace is that the storm seems to be moving rapidly and won't linger over any one area for long, though I suspect that river systems in the southeast will see much flooding.

Forecast cone for eye location: <https://www.nhc.noaa.gov/refresh/graphics_at4+shtml/213335.s...>

Forecast wind speeds: <https://www.nhc.noaa.gov/refresh/graphics_at4+shtml/213335.s...>


prediction and quick evacution is AI hallucination grade.

People died with flash floods, and it is worse if happening in the middle of the night, not to mention in the "middle of nowhere".


As long as housing is considered a financial instrument and problems like NIMBY and overly restrictive zoning continue to persist, none of this will happen.

this is incoherent: the dangerous areas will increase in size, then restrictive zoning will grow.

It isn't incoherent. You're just incapable of understanding the problem. You want more housing in areas that aren't at risk of flooding? Well, see my original comment. If you still have problems comprehending, that's not really my problem.

Few notes as an European NOT concerned by floods while being born in a relatively flood prone area: it's not about climate change but people who do not want to change. In the very past our ancestors have chosen settlements prone to floods sometimes, BUT with clear water available regularly because back than there was no effective pumped aqueduct and the need for clear water was the same than today, while the impact of floods was sometimes MUCH LESS than today: for instance many old homes was built of two-story with the ground level used only for animals or tools, in case of floods foods was kept at the first level and hay for livestock under the roof. In case of flood anything who suffer water wast dry, animals are easy to moves and steel/wood tools does not suffer much; today car's do not like being flooded and are not as easier to move as livestock in nature back then, we have electricity who not like water as well and so on.

Long story short, it doesn't matter if floods are more frequent or more powerful, our society have changed so our needs are different and we change homes and their location accordingly. This is a thing most people here reject vehemently. I have friends flooded multiple time, they can relocate economically alone as I do, they have no special constraint not to do so, but they refuse, they cry against the government, weather, anything else, they waste money to restore anything and keep going refusing the fact that when their ancestors have chosen a specific place there was different needs than today.

Similarly at less urgent level: back then zones with little circadian thermal variations was preferred because there was no cheap heating, so it was better for human health to be in a moderately change temperature than in a quickly change one every day. Nowadays where it's hotter in summer and we have p.v. and effective insulation it's much better for us living with large daily thermal delta because nights where we do not have p.v. we do not need to cool homes, and even if night are even cold it's not an issue thanks to insulation, while during the day we get "free" A/C with local p.v. Back than being near the sea was nice because yes, sometimes the sea invite itself inside the home, but every day we can go fishing with less time and efforts. Nowadays we can cars, roads etc being so near a certain place it's still useful sometimes but much less demanding than before and avoid salt and chlorine corrosion, submersion etc is much more important.

To going straight to the point: the world have always changes, civilizations have fallen because of that, it doesn't matter if today it's faster than ever or not, and it does not even matter much the various causes because the current climate change impose to adapt, AFTER such monumental effort we could discuss about how much we can mitigate the effects if we can or not. To implement the new deal we need anyway to rebuild anything because we can't on scale converge to electricity homes not designed to be heated with little energy, we can't generate enough, anyway aging infra and homes demand the same. It's not so "urgent" that anyone have to find a new home tomorrow, but it's about time to start discussing how to mass relocate food productions and people, starting from the most difficult areas a step at a time and year after another AND DOING SO CALMLY also makes the economy back on track because no one can de-localize the construction of a home, at least not for the largest part of the job.

> What about acknowledging the effects of improper land management (forestry, rivers, etc)?

Those are indeed a factor, and European nations as well as the EU have started programs to counter those 20th century artefacts (see "Renaturation"). But the amount of rainfall itself (measured) was extremely high, by any standard. The mediterranean sea was between 2 and 4 deg C warmer than usual, causing increased evaporation and in turn increased precipitation across Europe. (This has been widely reported)


I think that’s more of a topic for impacts to places like California and the Gulf Coast that have been heavily built up over the past fifty years despite their known issues with fires and hurricanes, vs the places in Europe impacted by these floods that have been occupied for many hundreds of years.

"X% of the variability in flooding explained by climate change, regressions show" probably failed the A/B testing for engagement.

Totally agree, climate change is highlighting the places we messed up but had enough stable weather patterns to hide it.

Lots of areas are getting absolutely flooded around Europe and it's basically because they drainer or changed the water courses, as well as making everything flat and smooth for (over)farming.

And then you get a week of rains and everything goes tits up.


> The World Weather Attribution (WWA) group said one recent four-day period was the rainiest ever recorded in central Europe

And having the rainiest four day period in recorded history


Copernicus is the go to tool I believe for the data https://atlas.climate.copernicus.eu/atlas

Having a look at the "Maximum of 1-day precipitation" dataset it is clear that it has increased greatly over the past decades which results - among other things - to flooding


If you are not the lazy one - what are those proper land managements? There were trees falling (not just in the cities) in Slovakia because it rained in one day like in a whole year.

> Do we just blame every "natural" disaster on climate now?

No.

> What about acknowledging the effects of improper land management (forestry, rivers, etc)?

Those are acknowledged, and there needs to be more focus on it.

Was there anything else, or is this just a blatant attempt at spreading doubt about climate change?


My issue is the "it's the climate" narrative takes all the coverage and distracts us from a lot of the low-hanging fruit things we can solve (forest brush, beaver damns in Poland, etc) as well as other environmental issues.

> The World Weather Attribution (WWA) group said one recent four-day period was the rainiest ever recorded in central Europe

Statements like the above are what should give everyone pause.

I think that statement can't be true.

Detailed measurements exists for less than a hundred years - yet the WWA is cock sure this is the highest rainfall ever. It goes to the credibility.


What do you think "ever recorded" means? I'll take a stab: "the most rain we could find credibly recorded in the data we have currently available to us."

If you have other data you should consider sharing it with them.

It may be natural fluctuations, but there has definitely been more forest fires and floods in the past 3-5 years than in the decades before them, and the high and lows have also been worse.

There have been numerous accounts of rivers retreating so much that land that hasn't been dry in almost 1000 years is again in fact dry.

Torrential rain have also become a lot more frequent where i live, where some locations gets weeks or months worth of rain in 30 minutes. Again, the amount of water may not be different, but the sheer volume and logistics of getting rid of it again may cause temporary flooding.

As for the current flooding in central europe, there were places that got a years worth of rainfall in days, which again causes rivers to transport a lot more water, and when the storm moves downstream it again pours more water down, into the already full river.


How do you get to that conclusion from your (2004) link?

Thanks for writing this. I hadn't clicked on the link and wasn't aware that the person you responded to was using data that's 20 years old. It's really awful that that is currently the top-rated comment.

I saw a report on the Schelde river. The total amount of water transported per year is not changing. But the difference in volume varies much more than it used to. We have longer periods with lower water heights, and more extreme heights on peak days.

This means a few things: Salinity of the sea perpetrates deeper on land. The risk of drinkable water buffers getting depleted grows. The risk for flooding rises.


Central Europe is in recovery from widespread deforestation. The regrowing forests act as a increasing buffer, weakening floods, overshadowing the effects of climate change.

And yet the increased flood event trend is despite forest recovery.

I'm still not convinced the flood event trend is actually increasing. And i should be if I'm living in the Elbe valley.

just to clarify: your source is from 2004.

Extreme floods in central Europe over the past 500 years: Role of cyclone pathway “Zugstrasse Vb” M. Mudelsee, M. Börngen, G. Tetzlaff, U. Grünewald First published: 02 December 2004


From (father being a fireman/worked in many search and rescue operations).

TL:DR from a fireman:

My father has always been saying "water will find a way". As progress+civilization expand, there is less and less free/open ground. Roads, parking lots, shopping centers, more roads, train tracks (elevated = blocking water), rivers being covered, fires, etc. Water doesn't care, it wants to go through - it will go through.

In the "good old days" it would rain X amount up on that mountain, and 10% of X amount will find its way towards your town. Now, burn that mountain, then add 50 roads/highways/etc. Now 40% of X amount will find its way towards your town.

By the way your town has 30% less free ground (roads, parking lots, etc.)

Thus, floods. You can (rightfully so) poke 100 holes on the above, because each town/village/mountain/river is different, but the point/spirit remains. "Water will find a way".

EDIT: I am always fascinated to read in the news that the (e.g.) "Old lake" flooded again after 30 years". Guys!!! The name of the location is "Old Lake", which means that for about a couple of million years water has been converging there. The fact that some people built there, doesn't Water/Nature from doing its thing.

This is what was defined by Daniel Dennett as a deepity.

> The World Weather Attribution (WWA) group said one recent four-day period was the rainiest ever recorded in central Europe

Surely you have data ready for peer review that contradicts this group of scientists?


The comment you replay to literally praises the fact that we have rain again, as opposed to several almost arid climate years in Europe.

Remember when the rivers were too dried up in France for the nuclear plants to function? Then everyone said that due to climate change we'd soon have an arid climate in Germany.

So, according to "peer reviewed data", we go from an arid 2020 to rain forest 2024 in just four years due to climate change. Remarkable.


Uhhh yeah, the whole issue with climate change is the system’s equilibrium getting narrower and narrower, so swings to extreme states become more common and more severe.

Yes, it is a remarkable behavior of complex systems like weather, but we see it in all complex systems as they spin out of control.

“You say the vehicle crashed by veering off the right hand side of the road, but in this video we see the car wildly veering from left to right across 6 lanes of traffic multiple times first! Remarkable!”


More extreme weather would mean the equilibrium state is getting wider, not narrower.

Think of a bell curve, with growing standard deviation.


Nobody whose home has been flooded is currently “glad that we have rain again”.

Yes, there have always been floods. But we had several events on the scale of "once in a century" in the last years... So, maybe... centuries don't last as long any more?

"once in a century" doesn't mean literally once a century, but rather a percentage probability over time. Having a couple in quick succession is actually not that strange.

It is not? Well, seems like the percentage probability is up when it happens more often.

Look at this table for example: https://de.wikipedia.org/wiki/Liste_von_Hochwasser-Ereigniss...

Seems like people either started documenting more or there are more floods now.


When was the last flood before Storm Boris that was like this?

FTA: "Central Europe's devastating floods were made much worse by climate change"

There are always been floods. But now they get worse. How much worse ? I don't know.

And as another HNer said, land management has its part in this too...


> There are always been floods. But now they get worse. How much worse ? I don't know.

From the OP: "But if warming reaches 2C, similar episodes will become an extra 5% more intense and 50% more frequent, the WWA warned."


But if you look at the number-crunching process that gave you those percentages, it turns out to be woefully fragile and sensitive to a whole range of other factors

Countless prior models were completely off, but this one is suddenly correct and needs to be treated as a reliable predictor.

The problem is that if you dare to question the accuracy, you are immediately labeled a "denier." The only acceptable answer is that no matter what the prediction is, if it is alarmist, it is correct.


I still think that all those oil and weapon depots exploding relatively close to Poland, the Czech Republic, Romania, Austria and Italy have something to say here.

Hot clouds travel far away in no time and a similar stormy behavior has been seen lots of times in pyrocumulus from big wildfires before.
