(*) "very approximately" because petrol, natural gas, etc., have highly variable prices across the board. Between countries, between types of end-user, between fuel chemistries, etc. Here's some back-of-the-envelope that #ChatGPT did for me ...

... Let alone the cost of the climate damage caused by the CO2 added to the atmosphere in the period between burning the fuel and DAC-ing that CO2. All not paid for by the #BigOil companies (and consumers).

Anyhow, glad to have that cleared up. Suck on that Newton! Well, actually, Johann Georg von Soldner (1776–1833).

And thanks to #Elbow's #GuyGarvey for picking this episode to mark #MelvinBragg's retirement. (4/4)

(Immediate caveat: I asked #ChatGPT)

Anyhow, it suggested that, rather than Newton's theories predicting this effect, it's *evolutions* of these theories by later scientists that predicted this effect. Further, that these amendments are actually incorrect (compared to #GeneralRelativity). (3/4)

I'm no physicist, but that claim (which I've heard before) doesn't align with what (little) I know about the foundations of Newton's theories. However, being a modeller, and thus instinctively not averse to armchair solutions to science problems, I thought I'd ask #ChatGPT ... (2/4)

Given (a) they installed Musk as one of their Fellows in a fit of fanboi excitement, and (b) have completely failed to dislodge him even after he went full Nazi on them, I no longer think they can be humiliated.

It's cute that we think this is them becoming our pets - as (SPOILER ALERT!) @unlikelyworlds.bsky.social has already written ("Beyond The Burn Line"), this is just them prepping to become our successors.

Do we know if this is just "bad luck" (i.e. caused by natural variability in avian flu occurrence) or is it something that's amplified by climate change, perhaps because warmer temperatures increase bird abundance on the islands, increasing the risk of infection?

We just needed a reputable source to do this first. Got that now.

It's a good target ...

And when I say "could do a lot worse", I'm speaking in classic 🇬🇧 understatement. It's a great introduction to both the basics of the C cycle, how our understanding of this has grown (partly thanks to @pfriedling.bsky.social), and a reminder of the policy hill that's still to be climbed.

Over my whole lifetime, a persistent reason for public support of the UK's (imperfect) socialised healthcare service, the NHS, has simply been looking over the pond to see the appalling shitshow of US provision.

(On the assumption, of course, that this moth has been doing the same thing as Biston betularia since the industrial revolution kicked-off ...)

The classic dilemma: does it want the short-term benefit of fossil fuel soot providing camouflage, or the long-term benefit of fossil fuel abandonment, reduced sooty camouflage, but less climate change ravaging its habitat?

A little treat for you @bas.ac.uk from #ScreenJunkies ... youtu.be/2DuX1l-clGY
