Triple-dip La Niña confirmed as BoM makes declaration
- rrreese 4y agoIf like myself you are confused as to what the byte Ordered Mark has to do with weather, BoM is the Australian Bureau of Meteorology. Triple dipping refers to this being the third year of La Niña in a row.
- backspace_ 4y agoThat is quite the confusion you got there. As la nina is a weather event, how is it related to Byte ordered Mark?
- DiggyJohnson 4y agoThey were just defining the unknown acronym in a playful way, presumably. You got the joke, but didn’t even notice.
- seshagiric 4y agoI was actually thinking it meant bill of materials. I am a programmer with construction background
- DiggyJohnson 4y agoLol, fwiw this was my initial reading as well.
- netsharc 4y agoHNer's religious devotion to "Don't change the submission title" is sometimes infuriating. It needs to say what BoM is and that it's confirmed in Australia.
- backspace_ 4y agoThere is no need to make comments like that, others will just complain about it.
- JasonFruit 4y agoWhich is not always a reason not to say something when you believe it's important.
- backspace_ 4y agoEven if it is important, there will still be an overwhelming amount of people who will not care
- JasonFruit 4y agoThat goes both ways. Even when something annoys you, there are a lot of people who don't care.
- indigodaddy 4y agoOnly takes a quick glance of the actual article to gain clarity on it though.
- culopatin 4y agoI thought it was Bill of Materials
- cstejerean 4y ago> Known as a “triple-dip,” a three-year La Niña stint has only occurred three times since record keeping began: from 1954 to 1957, 1973 to 1976, and from 1998 to 2001. So basically every 20 or so years and the last one was about 20 years ago.
- kelnos 4y agoIt might be interesting to compare the severity of the three prior triple-dips with the current one. My zero-research guess would be that this current one is worse than the last.

- 2muchcoffeeman 4y agoI was around for the last one in Sydney. Anecdotally, this seems like the worst floods. But that could also be because we’ve had 3 major events in a row: massive forest fires, pandemic, multiple bad floods.
- deleted 4y ago[deleted]
- hammock 4y agoIs this due to global warming?
- labster 4y agoPossibly, but in isolation it’s impossible to tell. Weather is a series of events; climate is a statistical phenomenon. But basically yes, all bad and exceptional weather is caused by climate change, at least in terms of moral equivalence. Many people somewhere is suffering from climate change, and you should pretend that it’s you, because you want to have the mindset that it has hurt people most everywhere.

- keepquestioning 4y agoThis is terrible. My Australian friends are complaining endless rain during summer is ruining their quality of life.
- notimetorelax 4y agoDublin would like to have a word with them.

- bobnamob 4y agoThe 3 “once in a century” flood events haven’t been great either
- keepquestioning 4y agoIs there any link to climate change & flooding?
- lisper 4y agoYes.
- culi 4y agoNot Australia, but a recent study[0] confirmed the Pakistan flooding (in which 10% of this country that's larger than Texas is underwater) links to climate change. Historically, tying events like this to climate change in a way that lives up to scientific rigor has been quite difficult, but techniques and available data have been improving. Allowing us to tie many extreme weather events to climate change, including: the seemingly never-ending droughts in the Horn of Africa, Mexico, and China, flash floods in West and Central Africa, Iran and the inland United States and searing heat waves in India, Japan, California, Britain and Europe. They refrained for making estimates for the Pakistan flooding, but earlier this year scientists found that the heat that scorched India and Pakistan this spring had been 30 times as likely to occur because of greenhouse emissions. July’s extreme heat in Britain had been at least 10 times as likely If you're looking for a mechanism of action for how climate change can make monsoons more deadly, it's likely to do with increased evaporation of water due to increased temperatures and the fact that hotter air holds more moisture [0] https://www.nytimes.com/2022/09/15/climate/pakistan-floods-global-warming.html https://www.nytimes.com/2022/09/15/climate/pakistan-floods-g...
- escapecharacter 4y agoThis sauce sounds delicious!
- dominotw 4y agoawesome ski season then?
- hammock 4y agoThe last one was terrible, what are you talking about
- iammiles 4y agoWas great in the PNW
- hammock 4y agoI ought to check it out this year. Where’s your favorite place to go? I’m thinking of how last year wasn’t hardly any snow and quite a few meltoffs in the east (where I did most of my skiing because of all the madness at the resorts all over). And the year before that worst avalanche year in memory for Colorado, if you do any backcountry
- rdudek 4y agoIt usually means below-average snowfall in Colorado. Other states might fare better than us.
- ISL 4y ago100%. The real strength of knowing these oscillations is the ability to get ahead of the cycles if you know they're coming. La Nina is great where I live, El Nino is not, but the reverse is true elsewhere.
- jnovek 4y agoI have migraines triggered by changes in the weather. The last two winters have been the most miserable of my life. This most recent winter I had a migraine that lasted an unbelievable 63 days starting the day after Christmas.
- taywrobel 4y agoWhile I definitely agree climate change is a clear and present danger, how do you know that your migraines are weather related? Sounds like a conflating of correlation and causation.
- jnovek 4y agoYour skepticism is reasonable. It does sound like an extraordinary claim. The relationship between migraine and weather is a studied phenomenon. I admit that I don’t personally understand the research on this topic, but I trust my neurologist. I do know that the proxy data for weather changes is barometric pressure, so it’s often specified in that way: “changes in the barometric pressure cause migraines for some people”. However I find the concept easier to explain to people with the phrase “changes in weather” because, in my experience, most folks don’t really know the relationship between the barometer and the weather. The Mayo has a layman’s discussion on the topic of weather and migraine: https://www.mayoclinic.org/diseases-conditions/migraine-headache/expert-answers/migraine-headache/faq-20058505 https://www.mayoclinic.org/diseases-conditions/migraine-head... EDIT: I forgot to mention. I “know” about the correlation because I’ve done hundreds of days of migraine journaling over the years and used that to find probable triggers. Unfortunately, that’s essentially the state-of-the-art in the field. :-/
- klyrs 4y agoIt's funny to me that people have unlearned the relationship between pressure and weather. I grew up in a house with a faux-antique barometer, and always took that for granted. Like reading an analog clock, this isn't knowledge that "kids these days" pick up. Which is still weird, because TV weather announcers always talk about the pressure when describing their weather forecasts. But of course, people want to know if their BBQ is going to be sunny, they don't want a lesson in physics. https://www.amnh.org/explore/ology/earth/make-your-own-weather-station/make-a-barometer https://www.amnh.org/explore/ology/earth/make-your-own-weath...
- andrewstuart 4y agoMelbourne's gigantic Thomson Dam is nearly full - a rare event. DamCam: https://www.melbournewater.com.au/water-data-and-education/water-storage-reservoirs/Thomson/thomson-dam-cam#/dc/latest https://www.melbournewater.com.au/water-data-and-education/w... 200KM from Melbourne, the Thomson is the main water storage and holds 1,068,000 megalitres. For comparison, Sydney harbour is 562,000 megalitres. The Thomson is at 96% full, and in fact most of Melbourne's dams are full or nearly full according to: https://www.melbournewater.com.au/water-data-and-education/water-storage-levels#/ https://www.melbournewater.com.au/water-data-and-education/w...
- bombcar 4y agoMany dams (Oriville for example) are important parts of flood mitigation - isn’t having the dams nearly full bad for that? Or is the rainy season over?
- 01100011 4y agoIf it were, i think they'd drain off enough water between storms to preserve some reserve capacity for flood control.
- quickthrower2 4y ago“Between storms” - no such thing for the last Australian summer
- ozzydave 4y agoSome dams have additional capacity for flood mitigation, like Wivenhoe Dam in Queensland. Unfortunately that’s not fool proof either: https://en.m.wikipedia.org/wiki/2010%E2%80%932011_Queensland_floods https://en.m.wikipedia.org/wiki/2010%E2%80%932011_Queensland...

- enviclash 4y agoLast I read was that the meeting of ice in Antarctica is increasing the probability of extending La Nina (sorry I lost the source). There are theories about ENSO states becoming more frequent with climate change, the most favoured one was a more stable El Nino (see PNAS article by Lenton on climate tipping)

- elevaet 4y agoHow will this affect winter temperatures in Europe, wrt limited gas supply?
- warble 4y agoWetter and colder in the north, warmer central Europe. Alps usually get a lot of snow. https://www.metoffice.gov.uk/research/climate/seasonal-to-decadal/gpc-outlooks/el-nino-la-nina/enso-impacts https://www.metoffice.gov.uk/research/climate/seasonal-to-de...
- 2000UltraDeluxe 4y agoIf the additional snow results in snow-covered roofs then it might actually help. 15cm of snow is very efficcient insulation.
- liversage 4y agoPrevious year (presumably the second consecutive La Niña event) the winter was exceptionally dry in the Alps leading to the current unprecedented snow and ice situation in that area so at least that year the snowfall was very limited. The article states that the predictions should't be regarded as forecasts so obviously some years might not have the expected changes, but in addition the only expected effect of La Niña in Europe seems to be a drier autumn on the Iberian peninsula so I'm not sure how you arrived at your statements.
- siquick 4y agoThe last 2 summers here in Sydney have been pretty much a writeoff due to the rain. And then before the double La Niña we had the bush fires of 2019 where the city had some of the worst air quality anywhere of the world. The (general shoddily built) houses just aren’t built for this weather - I’d say that more than half of my friends, family, and work colleagues have had to deal with mould in their apartments and houses. A huge reason for living in Sydney is the quality of outdoor life, then combined with extensive lockdowns, insane housing prices, and an openly corrupt and overbearing state government, it’s not been a great place to live for a lot of the population in the last few years.
- 10u152 4y agoWow, what a lot of hyperbole. Could you please show us some sources for the “openly corrupt” government? I’d also like some more information about the shoddily built houses. If we’re talking insulation then yes they’re not particularly well insulated compared to a Nordic country. But we also have a very mild climate compared to Nordic countries. New McMansions aren’t particularly well built but that’s the consumer driving the massive floor plan/minimum cost. Building, like any other product is very much up to the consumer in terms of what they want to prioritise. Specifically on mould, if the ambient humidity is, on average very high, no matter how well built your home is things will go mouldy. The solution is mechanical dehumidification/cooling but that comes with other penalties.
- hrayn3 4y agoThe previous Premier of the state (Gladys) resigned due to corruption. The new premier is involved in a plot to give sweet fake jobs to his political buddies, as well as various other schemes. The previous Labour government got swept out because of massive corruption. At a federal level, NSW politicians are involved in water grafts (Angus Taylor and barnaby Joyce) as well as huge handouts to nonexistent companies (great barrier reef foundation got 700 million dollars with no office and 5 listed employees and have done nothing visible with the money - except to say that it's been spent). NSW is very openly corrupt at all levels of government.
