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.

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.

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.

So much trash in this Matt Yglesias NYT rant but this specific bit where has has a go at @doctorvive.bsky.social is absurd even for him.

Eliminating fossil fuels is basic fundamental science shit, not environmentalist shit

A realistic look at the Senate map makes it clear that Democrats’ hopes hinge on states that have important fossil fuel industries. A Democratic Party that is open to responsible stewardship of those states’ natural resources can win majorities and invest in solutions for tomorrow — just as Democratic governors in energy-producing states like New Mexico and Colorado have used oil and gas revenue to finance a goal of universal child care and historic upgrades to conservation and recreation on public lands. The current view from the environmental movement, as expressed by the climate activist and author Genevieve Guenther, is that Democrats should ignore these practicalities because “reducing emissions by some marginal amount while locking in fossil fuel development prevents us from drawing emissions down to (net) zero.” In this approach to making policy, one starts with an end goal — two degrees of warming; global net zero by 2050 — and asks whether some specific new project is consistent with that goal or not. Since this would require a very rapid phaseout of fossil fuel use in rich countries, no new fossil fuel infrastructure is permissible even when the infrastructure would — like new pipelines to the northeastern United States or new liquefied natural gas export terminals — likely make emissions lower by promoting more rapid electrification. This mentality explains why green groups continually find themselves opposing bipartisan congressional negotiations to enact permitting reform legislation that would make it easier to build both renewable and fossil fuel infrastructure. A world that was heading to global net zero in 25 years would not enact such a reform, so it’s unacceptable. Reaching net zero CO2 or GHG emissions primarily requires deep and rapid reductions in gross emissions of CO2, as well as substantial reductions of non-CO2 GHG emissions (high confidence). For example, in modelled pathways that limit warming to 1.5°C (>50%) with no or limited overshoot, global methane emissions are reduced by 34 [21–57]% by 2030 relative to 2019. However, some hard-to-abate residual GHG emissions (e.g., some emissions from agriculture, aviation, shipping, and industrial processes) remain and would need to be counterbalanced by deployment of CDR methods to achieve net zero CO2 or GHG emissions (high confidence). As a result, net zero CO2 is reached earlier than net zero GHGs (high confidence). {3.3.2, 3.3.3, Table 3.1, Figure 3.5} (Figure SPM.5) B.6.3 Global modelled mitigation pathways reaching net zero CO2 and GHG emissions include transitioning from fossil fuels without carbon capture and storage (CCS) to very low- or zero-carbon energy sources, such as renewables or fossil fuels with CCS, demand-side measures and improving efficiency, reducing non-CO2 GHG emissions, and CDR47. In most global modelled pathways, land-use change and forestry (via reforestation and reduced deforestation) and the energy supply sector reach net zero CO2 emissions earlier than the buildings, industry and transport sectors. (high confidence) {3.3.3, 4.1, 4.5, Figure 4.1} (Figure SPM.5, Box SPM.1) B.6.4 Mitigation options often have synergies with other aspects of sustainable development, but some options can also have trade-offs. There are potential synergies between sustainable development and, for instance, energy efficiency and renewable energy. Similarly, depending on the context48, biological CDR methods like reforestation, improved forest management, soil carbon sequestration, peatland restoration and coastal blue carbon management can enhance biodiversity and ecosystem functions, employment and local livelihoods. However, afforestation or production of biomass cro… Energy Systems C.3.2 Net zero CO2 energy systems entail: a substantial reduction in overall fossil fuel use, minimal use of unabated fossil fuels51, and use of carbon capture and storage in the remaining fossil fuel systems; electricity systems that emit no net CO2; widespread electrification; alternative energy carriers in applications less amenable to electrification; energy conservation and efficiency; and greater integration across the energy system (high confidence). Large contributions to emissions reductions with costs less than USD 20 tCO2-eq-1 come from solar and wind energy, energy efficiency improvements, and methane emissions reductions (coal mining, oil and gas, waste) (medium confidence). There are feasible adaptation options that support infrastructure resilience, reliable power systems and efficient water use for existing and new energy generation systems (very high confidence). Energy generation diversification (e.g., via wind, solar, small scale hydropower) and demand-side management (e.g., storage and energy efficiency improvements) can increase energy reliability and reduce vulnerabilities to climate change (high confidence). Climate responsive energy markets, updated design standards on energy assets according to current and projected climate change, smart-grid technologies, robust transmission systems and improved capacity to respond to supply deficits have high feasibility in the medium to long term, with mitigation co-benefits (very high confidence). {4.5.1} (Figure SPM.7) We have options in all sectors to at least halve emissions by 2030 Limiting global warming will require major transitions in the energy sector. This will involve a substantial reduction in fossil fuel use, widespread electrification, improved energy efficiency, and use of alternative fuels (such as hydrogen). “Having the right policies, infrastructure and technology in place to enable changes to our lifestyles and behaviour can result in a 40-70% reduction in greenhouse gas emissions by 2050. This offers significant untapped potential,” said IPCC Working Group III Co-Chair Priyadarshi Shukla. “The evidence also shows that these lifestyle changes can improve our health and wellbeing.” Cities and other urban areas also offer significant opportunities for emissions reductions. These can be achieved through lower energy consumption (such as by creating compact, walkable cities), electrification of transport in combination with low-emission energy sources, and enhanced carbon uptake and storage using nature. There are options for established, rapidly growing and new cities. “We see examples of zero energy or zero-carbon buildings in almost all climates,” said IPCC Working Group III Co-Chair Jim Skea. “Action in this decade is critical to capture the mitigation potential of buildings.” Reducing emissions in industry will involve using materials more efficiently, reusing and recycling products and minimising waste. For basic materials, including steel, building materials and chemicals, low- to zero-greenhouse gas production processes are at their pilot to near-commercial stage. This sector accounts for about a quarter of global emissions. Achieving net zero will be challenging and will require new production processes, low and zero emissions electricity, hydrogen, and, where necessary, carbon capture and storage. Agriculture, forestry, and other land use can provide large-scale emissions reductions and also remove and store carbon dioxide at scale. However, land ca…

The world's largest carbon capture and storage complex planned for northern Alberta could use most of the surplus water in the giant Cold Lake-Beaver River basin, potentially forcing water rationing in the province. The $16.5-billion megaproject is a linchpin of the "grand bargain" energy deal signed by the Canadian government with Alberta last month. Many question marks hang over the project though, including how much water Pathways CCS — or any next generation carbon capture initiative — will actually consume.

They want to build them quickly, without regulation (like they're doing in the US), and run them on fossil fuels (mostly gas, while promising to phase it out, use carbon capture or build nuclear). While sucking us dry of our water in the process.

And Carney seems keen to help them do it.

Excellent new @commsdeclare.bsky.social work out today - read the whole thing here: commsdeclare.org/wp-content/u...

The Shell-funded education program urging students to 'design their own CCS' inspired me to re-share an original artwork of mine from a few years ago:

Design Draw a diagram of your new carbon capture and storage solution. Communicate Explain how and why your design will remove carbon dioxide from the atmosphere. Create Create a prototype of your design that you can test at home or at school. Dissolved carbon dioxide in water can be tested qualitatively using universal indicator as in Activity 1, or you may research alternative methods to test carbon dioxide concentration. and it's my cartoon from a few years back of someone just leaving a fossil fuel IN THE GROUND

Truly there is no mix of emojis or all-caps that can get across just how gargantuan 7 gigawatt of fossil gas is. This is obviously more spammy than most of these projects but if anything does end up built it'll still be utterly massive, even if it's a small fraction of this number
Celebrity investor Kevin O’Leary’s proposed $70-billion data centre, designed to run on 7.5 gigawatts of gas-fired power, could raise Alberta’s greenhouse gas emissions to levels not seen since the coal era, according to estimates obtained by The Energy Mix. Planned in an area battling drought, the project’s water needs would also be vast, rivalling the annual use of hundreds of thousands of Alberta households. Wonder Valley is still nowhere near getting off the ground. But if it ever gets built as planned, it could pump out 25.7 to 30.5 megatonnes of emissions a year, depending on what turbines and gas are used, and whether or not it includes carbon capture, found [pdf] Pembina Institute Senior Analyst Jason Wang, who crunched the numbers for The Mix. “It would be the equivalent of a return to the era of mostly coal-fired electricity,” said Wang. The reversal would set the province and Canada back about 20 years, matching the 27 megatonnes of coal emissions Alberta phased out between 2005 and 2023. The data centre complex, which O’Leary claims will be the “largest on Earth,” would require the equivalent of about 10% of all gas supply in Alberta once fully operational. It’s still just a concept, but in the Municipal District of Greenview where it’s planned, local officials are confident it will be built. “We’re about to pull off the largest project in Canadian history in this sector and I think Greenview should be really proud of that,” Chief Administrative Officer Stacey Wabick told council members at a budget review meeting in November. Wonder Valley was announced with great fanfare last December, a few days after the Alberta government unveiled a new data centre strategy designed to attract $100 billion in investments.

While the deal will require any pipeline to be built by the private sector, Mr. Carney, a former special U.N. envoy on climate change, and Danielle Smith, Alberta’s premier, acknowledged that no company currently backs the project. And neither those leaders nor other government officials identified any specific buyers in Asia for Alberta’s heavy oil, which most refineries cannot process. Despite all the hurdles and an array of issues that must still be resolved before pipeline construction could begin, Mr. Carney and Ms. Smith offered superlatives for the agreement’s potential. Want to stay updated on what’s happening in Canada? Sign up for Your Places: Global Update, and we’ll send our latest coverage to your inbox. “It creates an energy transition, all aspects of energy, but really sets the stage for an industrial transformation,” Mr. Carney said. “At the core of the agreement, of course, is a priority to have a pipeline to Asia that’s going to make Canada stronger, more independent, more resilient, more sustainable.” Ms. Smith promised that the agreement and further talks had the potential to reverse what she called a “deliberate phaseout” of Alberta’s oil and gas industry through federal environmental rules. But hours after the signing, Steven Guilbeault, the former environment minister who promoted many of the measures from which Alberta is now exempt, said that he was stepping down as Mr. Carney’s heritage minister. In a two-page statement, Mr. Guilbeault said that he strongly opposed the agreement and that any pipeline to the Pacific “would have strong environmental impacts.” Mr. Guilbeault will continue to be a Liberal member of Parliament. Several environmentalists, also raised concerns that the agreement could prompt other provinces to demand their own exemptions to climate laws, causing Canada’s system for mitigating climate change to gradually collapse. “We expected more from Mark Carney,” said Keith Brooks, the programs director at Environmental Defence. “This is a gift to the oil industry and Alberta Premier Smith, at the expense of practically everyone else.” In the agreement, Mr. Carney lifted a cap on emissions from Alberta’s oil and gas sector, exempted the province from federal regulations to phase out the use of fossil fuels for electrical generation and postponed a deadline for substantially reducing leaks of methane, a potent climate-change gas. The pipeline has been put in the federal government’s new fast-track approval system for large infrastructure projects. If the pipeline is approved, according to the agreement, Alberta will build a system to capture carbon emissions from oil sand projects, which burn large amounts of fossil fuel to extract, separate and turn oil-bearing bitumen into synthetic crude oil. The oil industry has been seeking federal money to finance that 16.5 billion Canadian dollar system (about $12 billion), which would move the carbon to underground storage. Some economists and many environmental groups question the economic viability and effectiveness of that project. Alberta has also agreed to rework and improve its carbon-pricing program for large industrial emitters, including the oil industry. Mr. Carney said that any pipeline must include Indigenous communities as investors and that it must also offer unspecified economic benefits to British Columbia. Both groups will also have to support the pipeline, he said. Getting the province and Indigenous groups to that point will be a struggle. While the agreement does not specify the route for any pipeline, it does indicate that the federal government is willing to end a ban on oil tankers off the northern coast of British Columbia. “There is no support, there is no project, there’s no interest in being a part of any oil pipeline,” said Gaagwiis Jason Alsop, the president of the Council of Haida Nation, a coastal First Nations group in British Columbia. “It’s a non-starter.” David Eby, the premier of British Columbia, said that he was concerned that a pipeline project without a private-sector backer would become a distraction from other major projects, calling it an “energy vampire.”
