ChatGPT - CO2 emission cost comparison
Shared via ChatGPT
chatgpt.com
(*) "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).
Cost of direct air carbon capture to remain higher than hoped
The cost of removing large quantities of CO2 from the air will fall in the medium term, but not as much as previously hoped. This is the conclusion reached by ETH researchers on the basis of new calcu...

And, for reference, the cost of #DirectAirCapture is very approximately (*) the same as the consumer cost of putting that #CO2 in the atmosphere in the first place. So, when you hear about expensive renewables and cheap #FossilFuels, remember the latter's price-doubling #Externality cost.
Holy fuck - @aiannucci.bsky.social's #StrongMessageHere today is all about my favourite undiscussed environmental concept: #Externalities. I'm never going to get any work done today if #BBCRadio4 keeps this up ... or, of course, I turn off the radio.
Anyhow, glad to have that cleared up. Suck on that Newton! Well, actually, Johann Georg von Soldner (1776–1833).

(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)
Today's return to an #InOurTime recording on #BBCRadio4 is about #Eclipses. Brilliant as ever, but it just made a point that niggled me. Namely that, though Einstein's #GeneralRelativity famously predicted deflection of light by the Sun's gravity, Newton's earlier work also did this. (1/4)
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.
Why most Indians blame global warming for extreme weather events
Over 70% of Indians in all districts say that global warming is causing severe heat waves. To better understand this, we conducted phone interviews with over 19,000 people between 2022 and 2025. Here ...

Hot take: Because it probably is responsible for these?
(I also wonder what the sales of 2020's #TheMinistryForTheFuture are like in India?)

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.
Coincidence I'm sure, but it's difficult *not* to make the #JurassicPark connection between #Radio4 reports of the discovery of Hitler's DNA on the #TodayProgramme earlier, with the #InOurTime on #Dinosaurs right now. It suggests some sort of #BoysFromBrazil remake to capture our fascist zeitgeist.
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.

Alternatively: "100% of #gamers believe #Steam has a monopoly on PC games that spares them from having to install multiple bullshit apps like #Uplay / #EAApp"
Sure, @steampowered.com's monopoly is bad, but so is having to tolerate a whole load of crap alternative platforms.

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.
Hey @royalsociety.org - hate to break it to you, but just because you were formed in the wake of Britain's last civil war, doesn't mean you'll weather one fomented by your most racist, most scumbaggy Fellow. You're embarrassing UK science by acquiescing to a fellow who doesn't even respect you.

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?

Thinking back to *that* rat, I'm only surprised that the AI didn't put a massive penis on Jupiter.
Not at all surprised at all that it was a predatory journal turned the handle on this one.

Thanks for this! It's useful to see. NERC seems hovering at ~25% (with noise).
There might be a glitch with the total line as it starts higher than any of the others. Or I'm misunderstanding the "mean".
