Absolutely no point in companies waving their ‘green credentials if they use AI, as it’s game over.

The shocking water level use and ridiculous power usage wipes out years of carbon capture etc etc in days

You can’t be ‘green and use AI

I ♥️trees. We're converting a hillside cornfield to a food forest. They bank carbon. As forests grow older, eventually the rate of CO2 removed is balanced by decomposition, ... produce fields 33% less efficiently. It is the CHANGE IN USE that changes net CO2.

Trees are wonderful clean carbon sequestration plants, but photosynthesis is far slower than the scale of human combustion of coal, oil and gas. The lecture by Dr. Scott Wing, Curator of Fossil Plants at the Smithsonian Museum of Natural History said that half of 200 million years of photosynthesis that had then been sequestered into coal, oil, and gas had been used up to date. Matching that statement to the papers and data published by the UCSUSA. Together they inspired the ridiculous yet scary at scale estimate of 5,475 years of plant sequestration PER DAY of human combustion of fossil fuels. The UCSUSA data cited papers stating that since 1751, humans had released 1,480 gigatons of CO2 (GtCO2). Dr. Scott Wing said that was about 100 million years of sequestration. With far greater precision we know human industrial combustion has released another 405 GtCO2 in the last 11 years. That is an additional 27.4% (or 27,400,000 years of sequestration) as modeled above... burned in 11 years (or 4,017 days). For the past 11 years, humans have burned fossil fuels at a rate of over 6,800 years of sequestered photosynthesis per day of human consumption. Short term, humans can use techniques like biochar mixed into soil to undo some of the harm, but plant respiration and decomposition of fallen leaves, branches and trees reaches a balance. Chris Martenson's Crash Course long taught the problem of reduced Energy Return on Energy Invested (EROEI) The need to also do Carbon Capture and Sequestration (CCS) makes it worse. Yet, all the IPCC pathways for keeping survivable planetary temperatures rely on CCS. Nick Breeze narrates this refutation of CCS at scale needed: "Survivable IPCC projections based on science fiction - reality is far worse" https://www.youtube.com/watch?v=8akSfOIsU2Y The prognosis for having photosynthesis save us from our industrial society's binge party on sequestered carbon has another problem. Earth has passed the optimal temperature for photosynthesis during the primary growing season. The mix of C3 and C4 plants that have evolved during the last 3 million years of Ice Ages can not efficiently handle the temperatures conditions of the Pliocene that current atmospheric greenhouse gas concentrations are generating Peter Carter assembled this info-graphic. The primary study referenced by Peter regarding terrestrial photosynthesis: https://www.science.org/doi/10.1126/sciadv.aay1052 Abstract The temperature dependence of global photosynthesis and respiration determine land carbon sink strength. While the land sink currently mitigates ~30% of anthropogenic carbon emissions, it is unclear whether this ecosystem service will persist and, more specifically, what hard temperature limits, if any, regulate carbon uptake. Here, we use the largest continuous carbon flux monitoring network to construct the first observationally derived temperature response curves for global land carbon uptake. We show that the mean temperature of the warmest quarter (3-month period) passed the thermal maximum for photosynthesis during the past decade. At higher temperatures, respiration rates continue to rise in contrast to sharply declining rates of photosynthesis. Under business-as-usual emissions, this divergence elicits a near halving of the land sink strength by as early as 2040. Fig. 2 Temperature dependence of the terrestrial carbon sink. Integrated global temperature response curves for normalized photosynthesis (green dashed line), respiration (red dashed dotted line), and a mass balance estimate of the land sink (blue solid line) in relation to current climate (gray bar), where the mean across each curve sums to zero. Photosynthesis represents the integration of C3 and C4 curves (Fig. 1) weighted by global fraction of C3/C4 photosynthesis (37). The gray shaded bar represents observed mean annual temperature range from 1991 to 2015 (9, 22), and vertical dashed line indicates current annual mean temperature at FLUXNET tower sites.

Seeing this come across my feed is making me scream a little because we do have an energy-efficient, entirely plausible way to do this that we already know exists - biocapture. Photosynthetic algae blooms capture carbon as a factor of their surface area, so we could absolutely use that w/vert farms

But how much profit was made pushing carbon capture as the solution and a reason to not reduce fossil fuel use? The billions wasted might just be the cost of business to keep burning.

The so-called low-carbon projects that major oil and gas companies promote include hydrogen, biofuels, carbon capture and storage, and carbon offsetting.
They are all false solutions that not only fail to reduce emissions, but also prolong the use of fossil fuels. www.eurekalert.org/news-release...

Rewilding before we start reducing meat & dairy aka land use is like deploying Solar Ration Management (SRM) or carbon capture storage (CDR) before we start reducing GHG. Putting the cart before the horse makes everything worse faster by definition.

Most power is solar, supplemented by fusion. The stations of the ALCEFS have one cylindrical base that always faces the Sun, and which is covered in solar panels. There are also dedicated uncrewed space-based solar harvesters that form a sort of pseudo-Dyson swarm, although the swarm is still very far from harvesting a majority of the Sun’s energy. The ALCEFS has most likely passed the Kardashev Type I mark a while ago (although it isn’t planet-based), but is still a long way away from the Kardashev Type II mark. Resources are gathered from asteroids. Each station of the ALCEFS has an asteroid in the centre from which resources are mined. Again, there are also dedicated uncrewed asteroid harvesters, mostly in the asteroid belt. Various specialised materials have been discovered, including a room-temperature superconductor, a hard self-healing substance used to build the walls of the stations and a transparent self-healing substance that is almost as hard and used to make the stations’ windows. Quantum computers exist and are powerful enough to make post-quantum cryptography a necessity, but have few applications otherwise. A post-quantum cryptography scheme is in place that is basically uncrackable. Molecular computers, which can perform computations and store information at the molecular level, are widespread. AI is highly advanced, approaching Artificial General Intelligence (AGI), but is still generally regarded as non-sentient. It took a while to get to that point, thought. The AI bubble of the 21st century burst to give way to the Third AI Winter, which lasted centuries. It ended when new techniques were developed that allowed AI to actually produce reliable, and not just believable, output. Slowly, AI’s bad reputation, well-deserved at the time but now largely obsolete, has been lifting. Holographic cameras (holocams) and holographic screens (holoscreens), have been invented, which can capture and display 3D scenes, respectively. Note that these are not the projections into 3D space that are commonly referred to as holograms in sci-fi. Holoscreens are flat 2D screens which can display images which appear 3D from all angles, as if looking through a window, without the need for specialised 3D glasses. They have a limited ability to display 3D images that appear to come out of the screen’s surface, which will look wrong if the image surpasses the borders of the screen or if there is something between the screen and where the image is meant to appear to be. Robotic manufacturing techniques are highly advanced, and just about anything can be manufactured to specifications entirely without human involvement within a few hours. Agriculture is also done fully robotically. All meat on the stations is cultured, grown in vats from stem cells, and does not actually come directly from an animal. There have been several advances in medicine. All surgeries are done fully robotically. They have advanced prosthetics. Organ transplantations are no longer really done, made obsolete by the implantation of artificial organs 3D-printed using the intended recipient’s stem cells. Bacteriophage- and virophage-based cures have been found for various illnesses. Progress has been made on life extension, with people at the time of the story typically living to 120 and occasionally reaching 150. The technology is advanced enough that if those born now had access to the current state of the art throughout their lives, they might live to 200 or 250. That is, until an immortality drug, which can stop and even reverse ageing, is discovered, a key element of the plot of the story. This drug provides biological immortality, which means that those who take it can still die, but will not become more and more likely to die over time. With it, lifespans could be thousands of years long. Artificial photosynthesis was used to sequester carbon prior to the Impact. Diamond trees, a new technique that sequesters carbon in the form of diamond, is being developed for the terraforming of Mars. Although it has been proposed to use it for returning Earth’s atmosphere to how it was, this is opposed by the Terran survivors, who have lived for centuries at the elevated temperatures. And there is not much push to return to Earth, given it’d still be toxic to non-natives. The ALCEFS The ALCEFS consists of 126 space stations, together with the various solar harvesters, asteroid harvesters and other spacecraft that provide them with power and resources, transport people between them or complete other important functions for them. The process for becoming a citizen of the ALCEFS is quick, easy, straightforward and stress-free. The ALCEFS has done away with the concept of money. Everyone in the ALCEFS, whether resident or visitor, is entitled to essentially unlimited free food and drink, healthcare, education, robotic assistance and even most luxuries, and are allowed to stay at the temporary shelter. Each citizen has the right to a free home, either individually or shared with a group who agree to live together, appropriately sized to its number of inhabitants, meeting all their accessibility needs. People can request additional features for their home, and the stations will do their best to have them granted. Any surplus homes can be loaned for a time as supplementary housing. The stations are essentially fully-automated, no one is expected to work and it’s illegal to compensate for work done. All mandatory labour, including penal labour, is also illegal. The only human labour in the ALCEFS is wholly voluntary. The ALCEFS also outlaws pretty much any sort of trade, only allowing wholly voluntary gifts. If something is offered that comes with both advantages and disadvantages, that’s fine as long as the advantages and disadvantages are inalienable; that is, that it’s impossible to offer the advantages without the disadvantages. An example would be a medication that necessarily comes with unwanted side effects, when no equivalent medication without those side effects is available. The ALCEFS operates by liquid democracy. Each citizen of the ALCEFS has the right to vote on every issue, or to delegate their vote to a registered delegate. They can choose to delegate only for certain topics or wholesale. Anyone can suggest issues to vote on and second issues others have proposed. Any issue with enough support will be put to vote. Anyone can register as a delegate for any particular topics or all topics, and must pick a delegate level for each, a whole number starting at zero. Delegates can only delegate their vote to delegates of lower level for the relevant topic. This prevents cycles from forming, such as when two people each delegate their vote to the other. Upon registering, delegates receive a delegate number, which they can either make public or share only with select people, and only those with access to this delegate number can delegate to them. Those with access to this delegate number are also able to see how they voted. Citizens of the ALCEFS are also periodically assigned AI calibration duty, which involves answering a number of questions to ensure AI remains aligned with human values. This is not strictly mandatory, but is highly encouraged, and the closest thing in the ALCEFS to mandatory work.

Colour me unconvinced that the solution to all problems is to use public money to bribe the greediest among us into playing nice.

(And carbon capture is not an answer here; it's cost prohibitive, particularly when compared with the cost of reducing emissions.)

Doesthis technology actually work? What are the risks? Pieces of this tech puzzle are already well understood, but that doesn't mean it's been feasible thus far. Of the roughly two dozen direct air capture facilities already operational worldwide, none have been able to achieve the emissions reductions targets they proposed, several have created more emissions than they've sequestered and others have shuttered as funds ran dry. The limited results have not deterred governments and energy agencies from factoring this technology into long-term climate plans. In 2023, the Canada Energy Regulator projected the country will use direct air capture to remove between 46 and 55 megatonnes of carbon dioxide each year by 2050. Manitoba Hydro's projections say the province will be able to capture 10 to 12 megatonnes each year in that time with direct air technology - approximately a third of Manitoba's annual emissions. Critics are less optimistic.

From the article:
“There really is no example of this kind of project working at the scale that Deep Sky is proposing anywhere in the world,” Wilt said. That’s in part because carbon capture is easier and cheaper at high carbon dioxide concentrations. At a chimney, carbon dioxide can represent between four and 30 per cent of the molecules in the air. But in the open atmosphere, carbon dioxide makes up just 0.04 per cent of the air — about 400 parts per million. Extracting carbon dioxide at these low concentrations is a much bigger technical challenge with much higher costs. The International Energy Agency projects that direct air capture could eventually cost between US$125 and $335 per tonne of carbon dioxide, while Deep Sky’s carbon capture projects currently cost about US$1,000 per tonne, according to research by the Climate Action Team. A big part of that cost is driven by energy use.
