Qxf7+ is one of those moves that’s easy when I know it’s puzzle but sadly I’ll never spot in a real game.

The β€œpro” argument is that the leadership of the Royal Society is composed predominantly of cowards.

Hm....democracy pretty much requires that we settle differences of opinion through "bickering", unless you have a better solution?

That column has been really scraping the barrel for a while now. IMO.

The one change that really worked for me was giving up on reading it.

Apparently real.

This seems like an absolutely terrible idea to me. Oxford already has enough of a problem with generators of plausible bullshit. See: multiple PMs and cabinet ministers passim.

The arrest of four people after this incident is an outrageous affront to the freedom of expression enjoyed by UK citizens. It is a human right we all enjoy and is protected in law.

I would. They wouldn’t have raised the issue again if it wasn’t to find a way to change their position.

We are psyched about this as the ice ages are cool (sorry!) - but also as figuring out these processes by which the ocean took up 100s of gigatonnes of CO2 from the atmosphere in the past may help us better understand the controls on its capacity for carbon uptake in the future… πŸ“ˆπŸŒŠ

Elon Musk openly called for violence on our streets yesterday.

I hope politicians from all parties come together to condemn his deeply dangerous and irresponsible rhetoric.

Britain must stand united against this clear attempt to undermine our democracy.

The hallmark of a good scientist is being able to change their mind in light of new evidence. The leadership of the Royal Society is failing this test day by day....

Appalled by the violent scenes of police being attacked at the Tommy Robinson rally today. Those responsible should face the full force of the law.

These far right thugs do not speak for Britain.

Sam Altman’s next big idea is presumably to build a bigger LLM and then ask it how to reduce the hallucinations. Hopefully he’ll do this *before* he asks it to design a commercially viable fusion reactor.

I need you to understand what this country feels like right now for those of us who look different. I'm sitting here, trying to plan for Saturday, make sure I don't even need to go to the corner shop for milk, like it's Christmas Day or lockdown. Why? Because I live near where Yaxley-Lennon will 1/

Is Sam Altman really an instance of chatGPT? It's basically what you expect from generative AI. Word salad with no truth value, no actual correspondence with reality. It looks like an answer, it's syntactically an answer, but it doesn't have any value other than entertainment.

Look I know the life of a climate scientist *feels* like a long prison sentence but maybe you’re being just a bit hyperbolic here :-)

All the shortarses can’t reach the higher buttons! Equally ridiculously, lot of people would rather go to 5 and walk down to 2,3,4 than climb the stairs.

The effect of CH4 - as - CH4 is roughly 100 times greater than the effect of the CO2 that the CH4 is converted to. The number 64 comes to mind but (a) may be misremembering and (b) is years old if true.

10.09.2025 16:04 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

roughly speaking, never. Both values will stay fairly constant because the CH4 value relates primarily to the recent *rate* of emissions whereas the CO2 value relates to the total *cumulative* emissions. Sure, *eventually* the CH4 - to - CO2 pathway will accumulate too, but it's a way off (I think).

10.09.2025 16:02 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

It's not that complicated given an emissions scenario. But my intuition (in agreement with @mtobis.bsky.social ) is that the long-term effect of CH4 is unlikely to catch CO2 any time soon. Even if the short-term effect is a significant contributor (because CH4 is more powerful as a GHG than CO2).
