"Ultimately, the greatest #climate benefit for #DAC comes from geologic #sequestration for which there is no revenue opportunity beyond public policy support. Public investment in and support of #carbon removal technology has increased in the past few years, but more will be needed to scale sufficiently and avoid the worst impacts of #climatechange."
"And it’s important to note that #DAC offers quantifiable and permanent storage, whereas natural #carbon removal solutions like #trees are at risk of #deforestation and #ClimateChange induced threats like wildfires and drought."
"The range of costs for #DAC vary between $250 and $600 today depending on the technology choice, low-carbon energy source, and the scale of their deployment; for comparison, most #reforestation costs less than $50/tonne."

"#DirectAirCapture is currently categorized as “technology readiness level” 6 (on a scale of 1 to 9), meaning it’s still in the large-scale and prototype phase, not yet ready for full commercial deployment. But this also means there’s ample opportunity to improve performance and reduce costs through learning from early iterations of the #technology. "

#DirectAirCapture is... chemically complicated. Difficult to imagine an at-home method.

#Forests have the ability to store more #carbon, but in unstable conditions due to #ClimateChange, #grasslands stand more resilient.

I know the answer to this question is in one respect "trees", but is there tech to *more permanently* #sequester #carbon from the atmosphere available at the small scale level?
I'm picturing a #solar powered thing that then [performs magic] and the result is a lego-sized cube of carbon every 24 hours. What's the alchemistic process?

carbon offsets
Carbon offsets are at best a very limited resource and at worst a total scam:
* Even if it would work as well as possible, the earth’s land ecosystems can only hold enough additional vegetation to absorb 40 - 100 GtCO₂e from the atmosphere.
* Once this additional growth is achieved (and that takes decades), there is no capacity for additional carbon storage on land.
* The world emits 55 GtCO₂e into the atmosphere per year. So all we can offset is 2 year’s emissions at most.
So even if it would work (but zero evidence so far), offsetting is not a sustainable solution: it is too little and too late because we need to cut emissions dramatically (by 40 GtCO₂e per year) in the next 20 years.
And if that is not bad enough, in practice, it's even worse, because a lot of the saplings die in the first year, and the land used for tree planting was in general already sequestering carbon in its previous state.
So as it stands, carbon offsetting almost certainly leads to increased CO2 emissions, purely because those who buy them have no incentive to lower their own emissions.

Hey Fedi, do you know if there is a federated (perhaps even #ActivityPub-powered) cooking recipe hosting service? If not, let's 👏 make 👏 this 👏 happen!
I hate modern recipe websites. All of them are full with ads and tracking. The leading recipe hosting in my country loads over 30 different trackers, and that's excluding the ads!

Watched #TheWindRises yesterday with my son and we experience *all kinds of feelings*.
He barely watches movies - but he can sit through a studio #ghibli any day. Fascinating.

#BobbyFischer (where is he? I don't know, I don't know) was the world #chess champion from 1972 to 1975. His favorite chess set was in the #dubrovnik 1950s style:
"What I played with #Spassky in 92 was the original Dubrovnik set, and it's very, very rare, I mean, it's almost impossible to get one... to get one, if you can get one in good condition, you know, it's absolutely... I think it's the best chess I've ever played on…it's just a joy to play with, a joy to hold, the definition of the pieces, the design... it's just a marvelous set, but it's very hard to get one, I don't have it...”
“On photos you see me playing and analyzing, that's another Dubrovnik set, that was made later in #Croatia. I got that in #Zagreb around '70 and that's a great set, but they stole it... and the balance of the pieces, the pieces didn't fall over, and the design, just great, great set.” (https://www.dubrovnikchessmen.com/bobby-fischer.html)
