I'd say there might be an 'optimum' somewhere in between - on average slightly lower rate than replacement, aiming for sustainable decline without crisis, preserving cultural heritage - as human cultural diversity matters as well as biodiversity. But we lack intelligent discussion of this topic - partly as it’s hard for people to imagine intuitively how small annual changes integrate over time.I'd like to further develop my interactive model - designed for climate projections but including a demographic model, to help people experiment for themselves, including regarding potential changes in global migration fluxes.

As a kid, I learned to write i = i +1, before school maths taught me it can't. The point is, computers do iteration well, especially to model dynamics of real non-linear systems, while classical maths is good at finding algebraic solutions to equilibria - typically more theoretical than real. Calculus is great for understanding repeatable dynamics - such as waves in physics, also integrating over some distributions. But even without knowing that well you could still approximate stuff numerically with simple loops, test it, and if an inner-loop turns out to be time-critical or accuracy-critical (most are not), ask a mathematical colleague to rethink it - believe in iteration rather than perfect solutions.

Nowhere to be honest, due to discouraging geopolitical situation. We had a family project to (re-)learn together, but the lessons provided for my kids at school were poor quality, while at my age I doubt I'll ever get enough characters to stick, to enjoy interesting texts.Years ago gave a few lectures in chinese, about 二氧化碳，海洋 与气候，etc., but general vocabulary, cultural references, are harder than science.

From the photos, it also appears that the "sun god" isn't strong enough to penetrate the seasonal smog (maybe that's what they're praying for?).

I'm aware of the racism issue, I even observed it myself in China, even many years ago.
But i've also seen similar problems in other corners of the world. Such cultural concepts can change slowly, as they did over here.
Anyway, I doubt this would dissuade people trying to connect what will become the world's main supply of surplus young labour, with the world's greatest demand for care-services, combined with spare apartments, money, and a milder climate. Not saying it’s good or bad, just trying to anticipate future changes.

I agree. For global discussions, are many Indians going to learn Chinese, Swahili, Hausa, Arabic, and vice-versa ? Meanwhile international-english is the new latin... Even within India, the south insists to keep english as an official language, to avoid being dominated by more populous hindi-speaking north.
Alternatively LLM-translation may facilitate multi-lingual discussion, but in this case the language of software development may still be influential during such transition.
By the way - this is an important topic for future of lemmy, which should expand more towards the south - where's a good place to develop it (beyond such set of replies)?

That seems like a big change in one year. It may to some extent reflect delay, as on average chinese used to pair-up at a younger age than typical in europe, also maybe some feel old traditions aren't necessary to keep a stable family with children. But the article says, the core factors are economic. Even so, as they have built so many surplus apartments, the [real] prices must drop, I wonder how many years before they are trying to sell the chinese dream to migrants from Africa or elsewhere.

So far, he did - but just hoping maybe whatever blackmail P has on T won't work any more ... as he's got the votes (for the last time), also it seems mud just doesn't stick as more was revealed about his past deals with women and other dodgy business. They both follow the recipe book from 1930s germany, but that doesn't lead to peace.

Back in 2011, I with my young family took a local bus north from Mariana, which diverted through several villages including that one Bento Rodrigues just below the dam, soon to be washed away. Through gaps in the trees we could glimpse those huge orange lakes just behind earth dams - it was obvious even to a casual tourist that it was a disaster waiting to happen. But the bus was run by the mining company, like all services around there, I suppose that's why people didn't complain more.
By the way I was told Brazil didn't even make much from iron mines, as most of raw ore was exported to China, which got the real value.

Emissions grew in 2023, that's not the same as 'are now growing'. There is a good chance global CO2 emissions fall in 2024, mainly due to trends in China. Of course it takes time to gather data, but NS should be more careful with the headline.
The spinscore link has useful refs - but keeps mixing up CO2 emissions with "CO2 equivalents" including methane, landuse and minor gases. Methane rising is a big issue, but might potentially be turned around faster. Regarding landuse, deforestation was exacerbated last year by El Niño feedbacks - it's hard to separate the anthropogenic part of these fluxes.
Rather than simple headlines which encourage fatalistic doom, it's more useful to explain how some factors progress better than others. They are right to highlight growth in road transport and aviation (even if some growth still covid-rebound), although more effort still needed in all sectors.

Hmm. I'm still using a 2014 iMac, as its 27" 5k screen still very good for coding (with added memory). Sometimes develops a bunch of thin vertical lines, which come and go maybe dependent on temperature, but hasn't changed for for ten years and i can live with those. Just wish they'd continue providing security updates for it.

Odd that Estacio de França is now the terminus only of lines from the opposite direction - but it makes sense to run all across the centre.
