Household Air Pollution and Clean Cooking Fuels: Despite Efforts, Many Still Lack Access: LP Gas, aka Propane, Offers the Most Practical Solution: Efforts by the UN, WHO, and Others


     Programs to promote and subsidize clean cooking fuels have been around for a long time. The fuels they replace cause respiratory diseases, particularly among women and children who breathe the toxic smoke. While environmentalist elites in the U.S. try to depict natural gas and LP gas, or propane, as toxic because they do emit some nitrogen oxides (NOx), those other fuels, including wood, charcoal, kerosene, crop residues, dung, and even coal, emit far worse pollutants. Compared to them, natural gas and LP gas are clean. Hence, the relative term “clean cooking fuels.” LPG does not produce the fine particulate matter and soot as the solid fuels do, and that makes it much healthier for those in the home, especially when the stoves are unvented, which is often the case.




       Jennifer Hernandez and Vijaya Ramachandran wrote an article about clean cooking fuels in The Ecomodernist that highlights the work of Kirk Smith in solving this problem over several decades. They write:

Beginning in the early 1980s, Smith studied the consequences of cooking with solid fuels in poorly ventilated homes. He and his colleagues documented the links between household smoke and serious illness, including childhood pneumonia, chronic lung disease, and cardiovascular disease. His work on clean cooking in India helped transform household air pollution from a largely overlooked problem into a major public-health and development priority. Smith worked with Indian researchers to measure women’s exposure to smoke from traditional cooking fuels such as wood, dung, charcoal, and crop residues. That fieldwork helped establish the scientific basis for understanding household air pollution as a serious cause of respiratory and cardiovascular disease, especially among women and young children.”

     Smith argued that slightly cleaner biomass stoves were an inadequate solution and advocated for the use of LPG.

By documenting the risks of solid-fuel cooking and making the case for clean fuels at scale, Smith helped shift clean cooking from a niche stove-design issue to a central question of health, gender equity, air quality, and development. Smith and his collaborators showed that household air pollution was among the world’s largest environmental health risks, contributing to millions of premature deaths each year.”

     The World Health Organization notes that about one quarter of the world’s population, or 2.1 billion people, are exposed to high levels of household air pollution. This is expected to fall to 1.8 billion people by 2030, which is great, but not nearly enough. These toxic cooking methods are estimated to cause 2.9 million premature deaths per year, including 309,000 children dying per year. Sub-Saharan Africa leads the world in lack of access to clean cooking fuels, with an estimated 923 million people lacking access. This is where the majority of people lack access to electricity.



     The specific diseases caused by toxic cooking fuels and their occurrence are listed by the WHO below:




     The WHO points out that rural people are especially affected by the lack of clean cooking fuels.

There is a large discrepancy in access to cleaner cooking alternatives between urban and rural areas: in 2021, only 14% of people in urban areas relied on polluting fuels and technologies, compared with 49% of the global rural population.”

     Of course, there are fuels cleaner than LPG. These include electricity, solar, biogas, and ethanol, but biogas cleanliness is variable depending on how processed it is. These options are often not available and not affordable.  

     They list another benefit of switching from wood and charcoal to LPG. It saves the local forests from being stripped away as they have in several places in the world, including central Africa and Haiti.

The contrast between Haiti and the Dominican Republic illustrates the point. The two countries share the island of Hispaniola and have similar environmental conditions, but they have followed very different cooking-fuel paths. The Dominican Republic shifted much more of its household cooking away from wood and charcoal and toward LPG or electricity, while Haiti has remained heavily dependent on charcoal.”

     Forests in Haiti have been cut down, while those in the Dominican Republic have been preserved. This is a major reason that flooding causes such devastation in Haiti but not in the Dominican Republic. Forests stripped for cooking fuels in Africa have led to destructive landslides that have killed many.

     Another issue is that women and children spend considerable time sourcing and gathering these toxic cooking fuels, time that could be spent on education. It also puts them at risk for injury and violence.

     WHO also points out that indoor air pollution is a major contributor to outdoor air pollution.

     They note that Smith was concerned that restrictions on fossil fuel use due to climate change concerns would lead to restrictions on LPG use, which would ensure guaranteed health problems for billions of women and children. They write:

A targeted LPG subsidy for poor households must be evaluated as a public-health intervention, not as a generic fossil-fuel subsidy.”

     They stress that LPG must be made affordable, with subsidization as necessary. It should also be widely available. They argue that policy should support LPG as the major solution until affordable electricity is available. They also argue that Sustainable Development Goals (SDGs) should not be pitted against climate concerns.

The same principle applies more broadly. Energy policy should not be reduced to a choice between climate and development goals. Healthier and more prosperous societies are generally better able to invest in environmental protection, forest restoration, and cleaner energy systems. Climate policy should support energy transitions within poor households, to improve health outcomes and alleviate the burden of poverty.”

     WHO recently reported that the UN’s SDG on ambient and household air pollution has not been improving over the past 5 years but has remained more or less stable since COVID. There are three SDGs regarding ambient and household air pollution, listed below.



     
There are also efforts from the private sector that focus on problems like clean cooking fuels. One, I wrote about earlier this year, Energy Corps, was founded by energy CEO Toby Rice, his wife, and prominent geologist and energy expert Scott Tinker.

Canadian Wildfire Smoke is Bad for Americans., But U.S. Wildfire Smoke is Also Bad for Canadians, and Ways to Be Protected


 

     No one wants to breathe unhealthy, toxic air. Combustion in its various forms is responsible for particulate matter (PM), which is dangerous to breathe. It does not only matter how big the source is, but where one is relative to it. Sources of PM include wildfires, campfires, bonfires, wood-burning fireplaces, coal-fired power plants, biomass power plants, waste-to-energy power plants, coke plants, industrial combustion processes, diesel-burning transportation, home heating, ships, trains, jets, smoking, and many more. Wildfires can be a major and dominant force. Weather inversions can bring the smoke closer to the ground, where humans have no choice but to breathe it. This happens very often in places like California, where a significant portion of it comes from China and Southeast Asia. California consistently has some of the worst air quality in the U.S., due in no small part to its susceptibility to these weather or heat inversions. Thus, poor air quality events from wildfire smoke require two conditions: fires and a weather inversion to hold the smoke down.




     A few years ago, my car dealer’s repair shop offered a free cabin air filter replacement when Canadian wildfire smoke was present. That is one way we can protect ourselves. Another is simply staying indoors when the air quality is bad due to PM. Vulnerable people might want to wear masks or use home air purifiers. PM pollution can be dangerous, especially for vulnerable people. I wrote a detailed post on PM pollution last August.

     A group of Republican Senators just penned an angry letter to Canadian Prime Minister Mark Carney, demanding better forest management practices in light of three consecutive years of cross-border Canadian wildfire smoke events. However, sometimes the opposite occurs when smoke from U.S. wildfires impedes Canadian air quality. The letter included the following:

"Our hospitals are once again treating children, dialysis patients, and older residents for the effects of smoke that did not originate anywhere near them."

This is the third consecutive year we have had to write to Canadian officials about a crisis that Canada has the tools to prevent and has chosen not to."

     The pic below shows Vancouver in 2020 under a blanket of U.S. wildfire smoke.




     I don’t know whether Canada could manage its forests better to prevent fires or not. Experts have noted that there are other climate and weather factors that make fire more or less likely. According to an article in Cleveland.com:

Canada’s forests have always experienced wildfires as part of natural ecosystems, but scientists say today’s fires are increasingly occurring under conditions that allow them to grow larger and burn longer, according to CBS. Warmer temperatures, reduced snowpack, dry vegetation and prolonged drought create landscapes where fires can ignite more easily and become more difficult to contain.”

Forest management practices, including removing excess vegetation, conducting controlled burns and creating firebreaks, can help reduce wildfire risks in certain areas, USA TODAY reported. But experts say those tools cannot completely prevent large-scale fires, particularly when weather conditions create extreme fire behavior across millions of acres of remote forest.”

     Canada’s fires in recent years have broken records. They did not change their forest management practices that had been sufficient until the more recent fires. Perhaps they should intensify those efforts, but it’s not likely that will solve the problem.

Scientists and wildfire specialists, however, caution that blaming forest management alone overlooks the broader forces driving today’s fire seasons. They say a combination of climate change, weather patterns, forest conditions and human decisions all contribute to the increasing frequency and intensity of wildfires.”

     Ohio Senator Bernie Moreno said he would introduce legislation to sanction Canada over the wildfire smoke, and another GOP senator from affected Michigan quipped:

Unless you want to become the 51st state, learn to manage your forests.”

     I think the proposed sanctions and the rhetoric, including calls to enter Canada and fix the forests for them, are uncalled for, disproportionate, and an insult to our friendly neighbors.

     Moreno called for forest thinning, fuel reduction, prescribed burns, and beefed-up enforcement against arson. I don’t know how much that would help. Some major fires have been started by prescribed burns that got out of control. Detection and enforcement of arson is difficult in any case.

Addendum - right after I posted this, I got in my car and drove to town, noticed the smoky air, and even smelled it. Then my A/C stopped blowing cool air. Then I remembered to set the air to recirculate so that no air comes in from outside. This was a recommendation for smoky air and also for hot days in general. It's possible that my cabin air filter got clogged. I may pull it out and either replace it or clean it. I was lucky that after a while, it started blowing cool air again.

AAPG Subsurface AI Special Report: Summary & Review


     This special report was sponsored by Aspen Tech. AI in oil & gas is not new. Beginning with simple neural networks and in the past decade with large language models and generative AI, the sector is embracing AI and achieving positive results. The report cites seismic surveying, reservoir evaluation, data validation, production strategies and optimization, multidisciplinary collaboration, predictive maintenance, and drilling optimization as examples. Digital twins, or real-time digital models, have been and are being deployed in several areas. Digital twins and generative AI have already been credited with increasing production and decreasing costs. Oil & gas companies generate vast quantities of data, including 3D seismic data, well logs, drilling data, and production analysis data. Thus, they are quite amenable to AI analysis that can find hidden relationships in the data.

     The report identifies four key themes for subsurface AI in 2026.

1. Simplifying Vendor Portfolios. This is important for reducing the siloing of data and putting it all in a single system. With a single encompassing platform, AI can act as an application programming interface (API). AspenTech’s Subsurface Intelligence “brings together domain-specific agents (for geophysics, formation evaluation, petrophysics, geomodelling and reservoir engineering) using AI capabilities.”

AI-propelled software is enabling companies to use a single platform to work with multimodal data. Data analytics software company Databricks’ Data Intelligence Platform bridges data warehouses (where structured data informs decisions, but raw data is often problematic) with data lakes (repositories for raw data). “

Leveraging Databricks, companies standardize schemas, manage quality, and keep datasets in sync as new sources come online,” says Enterprise Solutions Specialist at DataBricks, Reagan Kennedy. “With that data they can apply AI/ML capabilities, build out analytics, and expose the data via APIs and applications so existing tools can read/write against the same data instead of maintaining their own silos.”

2. Automation of Upstream Workflows with Agentic AI. They define agentic AI systems as systems that “autonomously act, decide, and orchestrate multistep workflows.” These systems are currently moving from the pilot phase to being fully operational. Output moves from making suggestions in generative AI to initiating actions in agentic AI.

“…generative AI might suggest a reservoir model to help with well planning. Agentic AI would use automation to rapidly create the model and then query asset-wide data to understand where the next best places to drill are or to predict the outcomes of different development strategies.”

Additionally, multi-agent frameworks can coordinate across subsurface disciplines simultaneously: One agent interprets stratigraphy, another models pore pressure, a third cross-references offset well data.”

     Agents are typically limited to what they were designed to do, such as analyze the geology of a single basin. Thus, location-specific and domain-specific validation is important. AI offers faster project analysis and better integration of data, and geologists should incorporate it smartly to save time and improve overall subsurface analysis.

3. The Open Subsurface Data Universe Launches. The Open Subsurface Data Universe (OSDU) was developed beginning in 2018 by major oil companies, including Anadarko, BP, Chevron, ConocoPhillips, Devon, Equinor, Exxon, Shell, and TotalEnergies, along with tech companies. It aimed “to create a single, open, cloud-native data platform where seismic, well log, reservoir, and production data could live, communicate, and be accessed by any application, regardless of vendor or operator.” OSDU was not without rollout problems in integrating different kinds of data, but it is still being perfected. AspenTech’s OSDU czar, Dani Alsaab, noted:

The future is multi-vendor collaboration in the upstream ecosystem, and we see ironclad commitment to OSDU as a differentiator for the future.” 

     The report notes that OSDU is still the best framework yet devised for the standardization of subsurface data. However, it has yet to be widely adopted outside of large oil & gas companies and still has challenges with interoperability and the integration of proprietary data.

4. Using AI to Train the Next Generation of Workers. They note that new employees can be aided by better AI integration of “how-to” functions in software so that software competency is improved and employee training is advanced. Software competency is a very important skill for modern geologists. However, it should not eclipse training in geology, but ideally complement it.

GenAI with domain guardrails is the way to transfer technical knowledge and experience to the next generation of workers,” said AspenTech’s AI CTO Heiko Claussen. “We see this as a way to give our four decades of technology leadership that has been built into our domain-specific software a new lease on life: It is an evergreen way to make future workers experts. It empowers us to add value to industry in new ways. There will be plenty of jobs, but the core skills will be how knowledge workers best leverage, interpret, and take advantage of these new AI tools.”     

     While I think this is all important, I also think that geologists should not abandon the basics of geology for AI-based approaches in all domains. We should always remember that AI functions best as a digital assistant, hopefully a remarkably competent one that can advance successful solutions to problems.

Lake Powell and the Colorado River System Face Continued Drought and Reduced Hydropower Output


     Lake Powell in Arizona is part of the Colorado River system. The U.S. Southwest has been undergoing a long-term drought, and water levels continue to drop, nearing critical thresholds for the Glen Canyon Dam’s ability to generate hydroelectricity. A recent water surface measurement recorded a level about 34 feet above the 3,490-foot “minimum power pool” at which Glen Canyon Dam can no longer generate hydropower. Previous projections suggested that the water level could fall that low as soon as August 2026. The U.S. Bureau of Reclamation (USBR) handles data for the lake and river system. There are wider potential implications of the ongoing drought. Current management involves releases from other reservoirs. 




     Newsweek’s Joe Edwards has been following the story and reports:

The wider stakes extend well beyond the reservoir. The drought-stricken Colorado River provides municipal water to about 40 million people, supports more than 8 billion kilowatt-hours of hydropower a year—enough for about 700,000 homes—and sustains 5.5 million acres of farmland, according to USBR.”

     A second concern with the situation is the possibility of future restrictions on downstream water use.




Glen Canyon Powerplant has eight generators with a total capacity of 1,320,000 kilowatts, according to USBR. As Lake Powell drops, the dam also loses hydraulic “head,” reducing the efficiency of power production even before turbines are fully shut off, according to reporting from the Lake Powell Chronicle.”







     In April, federal water managers issued emergency actions to shore up Lake Powell, moving water from the upstream Flaming Gorge reservoir and reducing releases to Lake Mead, amid record-low snowpack and deepening drought on the Colorado River. Releases to Lake Mead are important for residents, farmers, and customers downstream in Arizona, Nevada, and California. The reduced snowpack and prolonged drought have led to Colorado River levels at 36% of capacity. Edwards continues:

The agency said in April it intended to add up to about 2.48 million acre-feet to Lake Powell by releasing 660,000 acre-feet to 1 million acre-feet from Flaming Gorge Reservoir and reducing Lake Powell’s annual release to Lake Mead from 7.48 million acre-feet to 6 million acre-feet through September 2026.”

But USBR also acknowledged the trade-off: reduced releases from Lake Powell would “accelerate the downstream decline of Lake Mead,” with the potential for up to an additional 40 percent reduction in Hoover Dam hydropower generating capacity as early as this fall, it said.




     The emergency releases and withholdings issued are expected to raise Lake Powell’s water level by 54 feet to at least 3500 ft elevation by April 2027. The Flaming Gorge Reservoir was 83% full in April and is expected to drop to 59% full by next April.

     He cites a 2024 study published in Communications Earth & Environment that concluded that agriculture is responsible for 74% of all human uses of the river water and 52% of total water use. It also found that cattle-feed crops like alfalfa were responsible for 46% of the river’s direct water use. It will not be able to sustain that usage level, and some of those crops and nut orchards may have to be abandoned. 

     Recreation and tourism around the lake are likely to be affected as well. Local officials noted media headlines leading to cancellations. According to Bob Hembree of the Lake Powell Chronicle:

"The national media... has done nothing but put out sensational headlines saying there’s no water in Lake Powell, we’re going dead pool, all of the above," Franz said. She noted that these reports have a direct economic cost, mentioning that she had already heard from a business that "had four cancellations because of a headline back East."

     Hydroelectric output of the Glen Canyon Dam has long been decreasing. It used to power 40% of the nearby city of Page, but now provides only 20%, and power costs have increased.

     Current constraints on Lake Powell and the Colorado River Basin water supply are given below.




     Seven Western states and parts of Mexico share the greater Colorado River basin and must share the water resource. Thus, there will be continuing discussions in the future about how to manage it. The Dept of the Interior has indicated that it will manage the basin rather than have the states do it. Secretary of the Interior Doug Burgum met with Governors for the seven basin states, Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming, and their designees in April to discuss the concerning hydrology and plans for operations. He noted then:

Interior and Reclamation continue to coordinate with the basin states, tribes, Mexico and basin stakeholders as we make the decisions necessary to operate and protect the system.”

Assistant Secretary - Water and Science, Andrea Travnicek, noted:

As we weigh current conditions and prepare for future operations by working with states, tribal nations and stakeholders, the Department of the Interior and Reclamation remain fully committed to taking the actions necessary to reduce impacts on water deliveries, safeguard critical infrastructure, and preserve as much operational flexibility as possible.”

The Spaceship Earth Metaphor of Resource Distribution is Outdated: A More Expansive and Dynamic Approach is Needed


     I wrote about ecological metaphors in my 2021 book, Sensible Decarbonization. One metaphor that I covered was the Spaceship Earth metaphor, where the Earth, or biosphere, is considered to be a closed system with limited, finite resources. While that is true in some sense, it is also true that the limits of resource availability change based on costs and technology. New and cheaper ways of finding and developing resources make them more available than before. While total resources are indeed finite, technically and economically recoverable resources change via technology and cost-reductions, respectively. I wrote in my book:

     Another metaphor is that of the Spaceship Earth, which suggests the biosphere is a self-contained system. A systems view is very good as it allows us to look at relationships between components of the system. Earth systems science is often how we evaluate climate science. Visionary R. Buckminster Fuller popularized the idea of spaceship earth in his 1969 book, Operating Manual for Spaceship Earth.  Fuller was contemplating how to solve human problems in his works, in which he developed his conceptions. He tried to balance achieving the benefits of innovation with achieving the benefits of sustainability. Of course, humans are a part of the Earth system. We are not separate from nature, which is where some ideas put us. The Earth system involves many chemical cycles: carbon, nitrogen, etc. Oliver Morton, in his 2015 book on geoengineering, The Planet Remade: How Geoengineering Could Change the World, sees the spaceship Earth metaphor as an unnecessary separation of humans and human well-being from the Earth system. A ship has well-defined limits (the notion of “carrying capacity” came from ocean ships) and a purpose. The limits of the Earth system are much less clear, and any notion of purpose, especially some preordained one, is pure fantasy. Morton writes:

The question is not how to ‘save the planet’ as it was, but how the planet can be remade in a way that works while respecting the rights of people living on it. It is a task that calls for imagination and compromise much more than for naval discipline. It is a task of homemaking, not ship handling.”

     I read Fuller’s book in the 90s, and it was fun and a bit fascinating. He was an interesting guy. Fracking pioneer George Mitchell was a huge fan of Fuller and tried to design his town project with Fuller’s ideas of sustainability and circularity. Fuller did write a little about metaphors, including the following mind-bending quote:

We are prisoners of our own metaphors, metaphorically speaking.”

     Marian Tupy of HumanProgress.org wrote an essay in 2023 criticizing the spaceship earth metaphor based on David Deutsch’s book ‘The Beginning of Infinity: Explanations That Transform the World,’ which offered a detailed critique of the metaphor.

     Deutsch’s book challenges the closed-system assumption of the metaphor, citing human creativity and ingenuity as a way to exceed resource limitations. Notions of mining the moon or asteroids for materials would expand the system beyond the Earth itself.

     Deutsch cited water scarcity as being overcome by desalination technology, which can remove that scarcity where applicable by tapping resources that were previously seen as untappable.

     He cites knowledge and creativity as the means to overcome limitations and as the key drivers of human progress. Deutsch uses the example of the Green Revolution in agriculture as one way humans overcame limitations of food production to vastly improve the availability of food globally. One could also cite the development of synthetic fertilizers via the Fischer-Tropsch process. Humans excel at solving problems and making processes more efficient and economical. Another example he gives of the power of knowledge and creativity to overcome limitations is medical advancements, which enable people to live healthier and longer lives.

     Deutsch also argued that sustainability by itself is not adequate, and as noted, Fuller sought to balance it with innovation, and he does as well.

Deutsch argues that a focus solely on sustainability is limiting. He contends that progress and growth are driven by the pursuit of new ideas, the development of knowledge, and the continuous improvement of explanations.”

     Deutsch also advocates for a pro-growth mindset as an important motivation for innovation.

Deutsch suggests that a pro-growth mindset encourages the exploration and development of new technologies, enabling continuous improvements and expanding the possibilities for human progress.”

     Deutsch also argues that the spaceship earth metaphor is more easily associated with a pessimistic outlook, hence its adoption by catastrophists. There are even darker metaphors related to spaceship earth, such as ecologist Garrett Hardin’s idea of lifeboat ethics, a metaphor that says there is no room on the boat to help more than the boat will hold. This idea was used to argue against helping the poorest people in the world, the ones most in need of help. Deutsch suggests that an optimistic outlook can be fostered by expectations of harnessing the power of knowledge and creativity. He presents space exploration as an example of an optimistic pursuit. Being pessimistic would entail less likelihood of venturing into space at all.

Deutsch argues that optimism fuels the pursuit of ambitious goals and drives innovation, leading to significant advancements in science and technology.”

     He favors innovation and technology rather than conservation and limits as the best means to solve environmental and resource scarcity problems. He cites strides in clean energy development as an example where innovation is having positive environmental impacts.  

     Deutsche highlights human exceptionalism, how our ability to control our environments, in detail, is unparalleled.

     Tupy offers an apt summary of Deutsch’s ideas:

In summary, David Deutsch’s criticism of the concept of Spaceship Earth in The Beginning of Infinity challenges the prevailing view that Earth is a closed system with limited resources. Through a range of examples, including asteroid mining, water desalination, the green revolution, medical advancements, clean energy technologies, space exploration, and the eradication of smallpox, Deutsch emphasizes the potential for resource expansion, the transformative power of knowledge and creativity, the importance of a pro-growth mindset, the benefits of optimism, and the capacity for humans to address environmental challenges through sustainable solutions. By employing these examples, Deutsch invites readers to reconsider the limiting assumptions of the Spaceship Earth concept and embrace a more expansive and optimistic perspective on human potential and progress.”

‘Buy, Borrow, Die’ Strategy Works for the Super-Wealthy, Despite Bezos Saying It Isn’t Real


     

     What is the ‘buy, borrow, die’ strategy to optimize wealth? According to an article in Moneywise:

The aptly named “buy, borrow, die” strategy was developed by Professor Edward J. McCaffery in the 1990s to describe how rich people get — and stay — rich by paying less in taxes.”

Buy, borrow, die” is a strategy in which wealthy people accumulate appreciating assets, borrow against them and use the estate to pay off the debt after they die. It works because of how taxes are assessed: Not every financial move is a taxable event.”

Buy a car? Generally, you’ll pay taxes. Earn money? Pay taxes. Sell $62 billion in stocks? That’s a taxable event. But if you borrow money against those stocks — as Elon Musk did to buy Twitter in 2022 — that’s debt, not income and it isn’t taxed.”

In addition to avoiding taxable events, the “buy, borrow, die” strategy also allows whatever assets you borrow against to continue to appreciate, making you even more money. And while you’ll obviously pay interest on the loan, for the uber-wealthy, the math can still work out in their favor.”

     Jeff Bezos has claimed the strategy is not real and not used by the wealthy, despite evidence to the contrary. Elon Musk and Larry Ellison are thought to use the strategy.

The highest income tax bracket, for those earning over $640,601, is 37% (4) but interest rates on loans are typically much lower. In Musk’s case, he would likely have paid capital gains tax had he sold his stocks, which are typically taxed at around 20% (5) — still higher than most interest rates.”

     What irks me about this is that only the wealthy, and specifically the super-wealthy, can and often do benefit from this. The strategy is not available to most investors. The super-wealthy can easily provide collateral for any kind of loan and often provide it in stock. They are already significantly undertaxed, and this strategy allows them to avoid even more taxes. The strategy works best when interest rates are lower since it is interest that is paid instead of taxes. New policies, such as taxing certain loans or loan amounts, could limit the strategy, but no such policies are currently under consideration. The practice also irks me because the world’s wealthiest humans are able to increase their own wealth through this loophole and increase overall wealth inequality, which is already beyond absurd levels. It is effectively a wealth preservation strategy available exclusively to the super-wealthy. 

     Below is a Microsoft CoPilot summary of the practice:

RMI’s Five Oil & Gas Myths Regarding Methane Emissions: Since Gas Waste Drops When Prices are High, They Say Companies Capture Methane for Profit When it Benefits Them


    This article from the Rocky Mountain Institute (RMI) explains some aspects of methane emissions reductions in the oil & gas sector that are often misunderstood.

Myth 1: In terms of pollution from methane emitted during production, all oil and gas is the same. Some oil & gas fields emit more methane than others. Associated gas from oil wells is often deemed too expensive to produce along with the oil, so it is vented or flared, which results in methane and CO2 emissions, respectively.

Myth 2: Gas leaks are minimal and not too costly. Methane can leak from several different points in oil & gas systems, including valves and controllers, condensate tanks, flanges, poorly maintained flares, and during blowdowns of pressurized compressors. Much more gas can be recovered than is currently recovered due to economics. They estimate Texas is losing $1 billion in annual revenue due to methane leakage.

Myth 3: Gas loss and methane emissions are inevitable and impossible to prevent. They state that gas loss or methane emissions are largely preventable, and the technology exists to capture that gas today. The most interesting section of this article is the graph below that shows how gas flaring and methane venting rise and fall with natural gas prices. When prices are high, more gas is recovered, and when prices are low, more gas is wasted. That clearly suggests that some companies are not doing all they can to minimize methane emissions.




Myth 4: Gas is natural and clean. They are not quite correct here. Gas is indeed natural. It often contains impurities, and some can be toxic, like hydrogen sulfide. Gas often needs to be processed from its field or natural form into a pipeline-quality product. Dry gas is generally clean and requires minimal processing. Thus, they are not quite correct here.

Myth 5: Gas supplies are reliable and prices are certain. This is true, of course. However, some regional gas prices are more predictable than others, and some supplies are more reliable than others. Geopolitical global price shocks have occurred, but some regions are protected by abundant and available low-priced gas and are less affected by global events.

Pielke Jr. Explains the Continued Retreat from High Carbon Emissions Scenarios


   

     Climate impact scientist Roger Pielke Jr. explains the recent CMIP-7 scenario retirements due to implausibility.  CMIP-7 concluded in April that the RCP8.5, SSP5-8.5, and SSP3-7.0 scenarios were “implausible.” Since these have been included in most or all past climate science, this is big news. So-called ‘business-as-usual’ scenarios will now show much less global warming. How much less?

The table below shows just how large these changes are in gigatons (Gt) of carbon dioxide emitted from the burning of fossil fuels to 2100 — both in terms of the highest cumulative emissions across the scenario set (in the first bullet below) and in terms of the scenarios designated as reference or current policy (second bullet below):




     The Medium scenario is considered to be most likely and in line with current projections. The low-medium scenario is possible with stronger decarbonization efforts. The carbon emissions of the most likely Medium scenario are nearly a third of those projected in the SSP 5-8.5 scenario.




     Pielke Jr. notes:

While MEDIUM is the only scenario framed as “current policy” in the CMIP7 set — at 3C in 2100 — it sits above other “current policy projections,” which you can see in the table below. In addition, the MEDIUM-to-LOW scenario at 2.3C in 2100 is just about at the lower end of the projections that assume that national pledges are met.”


     The temperature ranges given in the different projections that are considered plausible run from 2.2 degrees Celsius to 3.0 deg. C. 




     He also explains that the High scenario should not be treated as a business-as-usual scenario, but one in which policies are adopted that increase emissions.

Thus, the range from MEDIUM-to-LOW to MEDIUM — with medians of 2.3C to 3.0C in 2100 — can serve usefully as the equivalent of a baseline or reference range. The HIGH scenario, at ~3.4C in 2100, is explicitly designed as an exploratory scenario to illustrate a world in which policies are adopted that increase emissions. CMIP7 explains:

Clearly, this scenario is not a “business-as-usual” scenario nor the no-policy reference scenario for the other scenarios.”

This point needs to be emphasized. HIGH is not a baseline or reference scenario and should not be treated as such. I’m sure this warning will be ignored by some.”

     As he shows below, the most likely Medium scenario means that annual global emissions are projected to stabilize as they are currently close to doing, and begin to drop in the 2030s. That dropping is accelerated in the Low-Medium scenario. 





     With the new changes, we should see graphs in future IPCC reports that look much different. He notes that the current and pledged policies range is now below what RCP4.5 was presented as achieving with aggressive policy. Below, he gives his thoughts on the implications of the new scenario plausibility determinations, including some uncomfortable political maneuverability for those who favor more catastrophic scenarios and who want accelerated decarbonization.
