Good, makes sense, as Scala is ‘made in Europe’ (mainly swiss and polish teams), and makes very robust software. Only it’s under-hyped. Here you can try my interactive climate-system web-model written in latest Scala, which compiles three ways - to the web-app you see, to native code for fast calculations, and to a jvm desktop app (with 25 years history, originally java).
Yes. Persistent contrails - i.e. aviation-induced cirrus clouds which spread in supersaturated air layers - are indeed bad for the climate, but often their effect is ignored as hard to quantify, while the simpler small effect of short-lived contrails is conveniently cited instead.
Also, while all high clouds have a warming effect by reflecting infra-red radiation back to earth, there can also be a cooling effect due to reflecting solar radiation, which is greater when the angle of the sun is low. So the net effect is warming in the middle of the day and at night, but cooling in morning and evening.
SF6 emissions are bad news, but thanks for reporting it.
Wondering whether Solvay HQ in belgium had any role in covering this up ?
I recall using SF6 30 years ago to study ocean gas fluxes, but only microlitres, as we knew about it’s crazy high GWP even then.
Maybe Euroclear is not the only reason - rather a convenient excuse for De Wever to waste time - as his seat of power is Antwerp with a huge chemical industry partly fueled by Russian gas, and his party is right-wing nationalist and maybe more sympathetic to the Putin-Trump vision than they dare to admit (as not in line with sentiment in the country as a whole).
It’s well known that each person has to have a different account for each of those big-tech services. Whereas in the fediverse, the original idea was that one account can traverse multiple services. The problem as the OP explains, is that it may seem you are following your friend’s account, whereas actually you might see just a small fraction of it, and not be aware that there is more.
I think OP has a valid point - it’s not about experienced users, but newcomers to the fediverse, who may think they are following an account, when actually they only see a small part of it - there could be some indication of what’s missing.
That’s a rate of only 1.2% per year, was that your intention ?
This headline and several others relating to same ‘news’ are mixing up information about 2024 (which is what the GCB data tables show) and 2025 emissions which are expert-projections. Of course it’s useful to project for 2025, to inform the COP in Belem, but big collaborative data assimilation and analysis of sinks takes time, so the accurate data is about 2024 (you can download the most recent GCB data tables ).
Checking their ‘Key Messages’ for 2025, the headline figure of 38.1 Gt fossil CO2, seems to be a decrease compared to the last figure in the tables for 2024 ( converting units x 12/44 ) . This is hard to reconcile with projected national increases ( but those seem to me - just quick reflection - pessimistic compared with previous carbon-brief analyses ?).
In general it seems to me science-communicators do not help general understanding promoting reports by muddling up the years - global trends are changing, and blips related to weather and geopolitics vary from year to year. We’ll have more blips still to come this year.
Interesting concept, but the efficiency compared to standing turbines needs to be calculated based on the expected lifetime. What’s the leakage rate of the helium? What’s the resistance of the fabric (or whatever it’s made of) and cables to UV light ?
Most pre-putin-era russian music stars are in exile somewhere in europe. They should coordinate together, make a big concert in some safe place, with clear political messages, some might penetrate through to people behind the state-tv propaganda wall.
Yes, indeed there is always going to be a balance point, with most tasks in life. Thinking is hard, more effort devoted to one topic is less for another. But we can also get into a bigger mess by trying to tell people simple answers to complex problems.
Actually to be more specific I’m a climate-system model developer, it’s intrinsically a very complex problem, so I try to develop software to help people learn by experiment, and balance choices. You can see my current efforts here. Maybe it’s already too complex for some, too simple for others, I’m still trying to fill the gaps.
I don’t agree with this, the answer is not collapse.
To me complexity is beautiful, creating and maintaining complexity is the essence of what it is to be alive.
Although I’m no fan of hierarchy or big capital, there are better systems for organising, balancing feedbacks, and we need to keep thinking about ways to do this (which is why we’re here on lemmy).
While medieval societies based more on tribal loyalty were more unequal and hierarchical than modern ones, as well as sustaining far fewer people until the next famine or pandemic.
I consider Human Ecology as the concepts of ecology (including energy, system feedbacks etc.) applied to human society and all that depends on - which is broader than your description. I recall the activities of CHE in Edinburgh in the 1990s. However there are diverse interpretations, also the word ecology has different nuance in different languages (e.g. is used more broadly in french).
Makes sense from a human-ecology point of view (which was trendy in 1980s),
but that thread is rather fatalistic - a more useful question is what can we do about this ?
As a software developer, I’m also aware that there can be diminishing returns to increasing complexity and feedbacks, on the other hand more feedbacks can add extra powers and resilience, how to stabilise with a good balance ?

Although I don’t live there, I’d like to see more discussion of India on Lemmy.
Why just US schools? Such a rethink should apply to every country.
In my opinion, school holidays should be rescheduled to coincide with the best periods for outdoor activities (for example, here in europe I’d prefer the summer holiday to be in June which is cooler than July but with longer daylight hours). While for both extreme hot or cold (and dark) periods, it’s better that kids are gathered in a coolable / warmable institutional building, than assume that all parents can provide such a space for the whole day.
Current school holiday patterns date from 19th century traditions, when kids helped with planting in april and harvest in august, change is long overdue.
I used to sing while riding a bicycle around hilly edinburgh, can testify it’s good for positive psychology.
Well written article on complicated topic. I hadn’t realised - even as a belgian climatologist - that one plant was responsible for so much emissions.
I reckon that in europe as a whole, we have enough steel and need to shift to recycling it more efficiently (including dismantling some reinforced concrete structures, ol pipes etc), although that’s not the case in Africa, India with with growing population.
We used to have many fireflies around midsummer in our garden (in belgium) - until we got ducks, now they are fewer. Their larvae eat slugs and snails, so those ducks compete for the same food. I’d guess “pest control” is a bigger cause for decline than climate, in this case.
This article feels to me really out of date. Scala3 was launched nearly five years ago, The tooling and lib-support was indeed dodgy back then but works very smoothly now. Scala3 also broke Scala2 macros, and some people whose business-model was selling support for clever libraries built on those macros made a lot of fuss (bad publicity). Meanwhile Scala3 has new more robust macros which work fine.
I develop in scala an interactive climate-scenario model web-app . It’s running the model in your browser (500 years x 250 countries x many gases, sectors, feedbacks etc. - so it’s complex)… The scala code compiles to js (or wasm) -which is what runs this web app - but the same code also compiles with scala-native to run fast batch- calculations or tests. It also compiles to the jvm app like my older java code, but I rarely use this now.
Scala3 code looks more like python than java - minimal brackets, and much nicer to read and higher level than rust.
As for tools I just use Zed editor with Metals for LS, Mill for build, and other libs from the lihaoyi ecosystem, no web ‘frameworks’. Scala is both robust and flexible. In general - if the code compiles, typically it runs correctly first time, if not the very-intelligent compiler identifies precisely what to fix where (very different from so-called ‘AI’). So instead of reams of junk ‘tests’, it’s usually just enough to check whether my climate system plots look and behave as expected - higher level thinking.
As for Kotlin it was effectively a russian-led (at the time) fork of Scala, staying closer to Java - so less flexible, but they did much more systematic marketing - and I suspect some of that deliberately pushed blog posts knocking Scala.
What Scala lacks is promotion, so those following fashions of this hype-driven world won’t find it.
For those who use it, it’s a great language, to do complex stuff that scales robustly.
