@jessicayluo.bsky.social is a marine biogeochemist and ecosystem modeler at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), where her work focuses on how marine organisms transport carbon from the surface to the deep ocean, and how these dynamics shift under climate change.

SUPERB and angrily unvarnished response, by former BBC chairman, Lord Patten.

No itโ€™s important to listen to this. Because then you understand that many of them will do ANYTHING to keep power. Remember Musk got involved in the 2024 election after saying to Tucker โ€œif she winsโ€ I am definitely going to prison.

So we need to move knowing that nothing is off the table for them.

The ethical use case for SRM is one in which governance conditions fail to enable adequately rapid decarbonization, and then there is a revolutionary change in governance that allows effective and equitable management of SRM

Fortunately the people proposing this disgusting treatment of immigrants and their families are currently in opposition not in government. Frankly I'm ashamed that even a minority-party elected politician of my country can dare say this out loud. Gross attitude to my friends and colleagues.

It is to the credit of UStA that they cover the surcharge for staff (PDRAs, faculty, fellows), though not currently for students, for whom itโ€™s arguably even more of a burden and access issue. But that is surely a tenuous position in the currently HE financial climate.

I cannot stand the โ€œcritics sayโ€ framing. What on earth could you call the NHS surcharge โ€” a fee for a service that you concurrently pay taxes for โ€” other than double taxation? It is blatant to the point of absurdity. Dump it in the river.

Once more for the people in the back: you cannot ask people to pay many ยฃ1000s upfront for the *privilege* of *temporarily* coming to work and pay taxes in this country, give them nothing particularly unique in return, and expect that to be a sustainable situation.

The NHS health surcharge is a national embarrassment; and it would be if the affected group were not always perceived as โ€œforeignโ€, and โ€œprivilegedโ€ to be here at all.

It says right from the start โ€œyou will be treated differently hereโ€, and it shows our arse as a nation.

We killed them all. Every last one of them. And now they will never be again.

They lived their Curlew lives, migrated, cared for their young, and had every right to be here - as much as ourselves. And they did us no harm.

And we killed them all.

Presumably there was a time when many more of our 2nd order relationships existed through our shared commitments (to religion, community, leisure)?

Itโ€™s an interesting side note that so many of our second order relationships are about consumption. Our modern lives are steeped in transactions โ€” perhaps then itโ€™s not surprising that, unexamined, these relationships are seen as nothing more than transactional.

4. We pay again and again for a failure to raise taxes. Itโ€™s a false economy, for which we suffer in multiple ways.

This, from John, is fantastic.

I never really caught that first wave of the internet, but I certainly lament the whirlpool it has become.
