I like some concepts and design of Mbin, something to learn from, but I'd believe more in its growth potential if not written mainly in php.

Interesting observation and analysis, and illustrates the potential of more lemmy-mastodon interaction.
Indeed mdon like-federation seems weird but I presume it was setup this way for efficiency, to reduce the number of small communications? Although Lemmy has a backend in rust - more efficient than mdon's ruby - still I wonder whether the lemmy system of federating all upvotes would scale well if the number of users grows to that of mastodon and beyond ? Could there be some intermediate compromise solution (e.g. federate batches of 100 likes)?

I didn't discover Lemmy through search, nor did I ever use reddit - I found it from mastodon where a few people promote lemmy posts. Then gradually realised I preferred the community-focus here, compared to the individual-focus of mdon (although combining both could be good). As mdon has many more users, improving this inter-op would help to bring people here.

Trying to imagine what's the application of mats of electric seaweed - if the energy could somehow make them self propelling, and self replicating, could get interesting, big potential surface area ...?

Some good digging - indeed it is hard to understand all the different ways to define and interpret climate sensitivity.

Well written!

Clearly there's a big gap between greenwash rhetoric and practical reality, but that's not unusual all over the world. The big question here is not the design of the central buildings, but whether it makes sense, as long-term sustainable development, to relocate the capital, and it seems to me there are arguments both ways. Jakarta is low-lying, literally sinking into the rising sea, and the island of Java is overcrowded - so something had to change. The new capital will lead to some deforestation on Borneo, on the other hand by bringing elites nearby they may re-evaluate the value of the jungle, it could be harder to hide destruction. The new location has potential for sea transport, but may lead to an over-dependence on air-transport.
Maybe useful to compare with other countries that moved their capital for geographical balance, and to avoid rising sea-level and overcrowding, for example Lagos to Abuja, or the new egyptian constructions SE of Cairo.

Also the global impact would likely be much greater, due to the co-operation factor.
On the other hand, there is a time-lag to policy impact, also exogenous surprises (superimposing past presidents on that plot may be revealing).

It slows down, an effect of cold water from melting ice passing south of greenland, which has a local cooling effect, while the atlantic as a whole gets warmer. Consequence is a greater heat contrast along that front, which may intensify the sequence of low pressures bringing wind and rain, which is what Ireland has just experienced this summer. But the high-resolution models do not show that AMOC stops abruptly, that was a feature of simpler models designed to replicate palaeoclimatic changes at the end of the ice ages, when the amount of ice available to melt was much higher.

Ireland has a long coastline but most of it near mountains, so there is fortunately scope to gradually retreat uphill. The large flat part is in the middle - the central Shannon basin is only 35m above sea-level, but unless East Antarctica goes too, that's safe for the moment. As for temperature rise, it's a cool country that may expect relatively little warming, due to the cold blob south of greenland, at least while ice continues melting. So, Ireland may need to prepare for large influx of people escaping heat elsewhere.

Key message remains that methane is "the strongest lever we can quickly pull to reduce warming".
It's not runaway, but there is a positive feedback of methane increasing its own lifetime by using up atmospheric oxidising capacity. I note also, new to me - "an increase in decomposition rates from wetlands as higher temperatures interacted with La Niña conditions in the tropics" - so during El Niño we get more CO2 from forest fires, but during La Niña more CH4 ... - how to lock-in that carbon ? I also wonder how much methane is coming from Russia recently, whose government cares the least of all.

Stability is indeed a strength of EU - effectively averaging over all the countries smooths over political oscillations - which is useful for tackling long-term policy problems (like climate). I'm not advocating majoritarian voting where 51% overrides 49%. However with ± 30 countries, one or two should not block the rest - the current system leads to transactional brinkmanship where the last hold-outs get some prize in return for postponed obstruction. I've seen similar (worse) problems in UN climate negotiations - also due to "consensus" principle.
