In connection with "how do we feed ourselves without disrupting the climate," Research needs for a food system transition by Sunala Shukli McDermid and coauthors and published in Climatic Change first reviews what we've learned of impacts from our agriculture and in particular animal husbandry on Earth systems, including climate. The review's conclusion remains familiar: there's an urgent need to make some major changes. That's going to need a lot of attention to a lot of detail, and how to work at that level is the main thrust of the article's purpose. The authors go on to argue we need to practice concerted, systematic research in key areas of agriculture and agricultural policy so as to inform our steering of transitions, identify pitfalls, and make translating scientific findings into policy more efficient. They break this big overall challenge into more digestible conceptual chunks, with suggestions on how to get started.
Also having an emphasis on animal agriculture but with specific remedies in mind come Biloltto et al. with Carbon, cash, cattle and the climate crisis, in Sustainability Science. The coworkers suggest several key methods to significantly reduce the greenhouse effects of continuing to consume animal protein from large mammals, including vaccination of animals so as to control enteric methane.
Fuceri, Ganslmeier & Ostry ask: Are climate change policies politically costly? A key question given the risk appetite of many policiticians. The team reports some fairly palatable answers in Energy Policy. Policies can be effective yet relatively benign when it comes to generating resentment in electorates if delivered with sensitivity to timing and with economic impacts buffered and damped by appropriately choosing points of policy application. As well it's important not to leave people "in the lurch:"
Our results show that when CCPs are adopted in times of increasing inequality, political costs are magnified. However, redistributive instruments targeted at the individuals experiencing higher economic insecurity are viable strategies to overcome the political fallout from CCPs and support governments to take necessary action without risking losing office.
Tensions and heat in climate mitigation policy discussions often rise when certain technologies are in play. For different reasons this is true of both nuclear power and carbon capture and sequestration. Each carries baggage. Nuclear power has as history of hard-selling by enthusiasts who've often downplayed or even denied various challeges arguably unique to this general area of technology, with the credibility of the entire nuclear enterprise thus dragged down as we've experienced a few disaster cases wildly outside of promoters' range of negative possibilities. Meanwhile, carbon capture and storage (CCS) is currently in favor with legacy fossil fuel concerns as a means of prolonging monetization, with "will it actually help" being a minor detail in such cases of narrow self-interest. Even so, it remains the case that each suite of technologies may yet play a useful role in our continuum to permanently sustainable energy sources. In this week's government/NGO section are broad updates on prospects of both, with each report sounding a bit boosterish on its face.

Clean Energy Now for a Safer Climate Future - Pathways to Net Zero in the United States by 2050, Jacqueline Ennis and Amanda Levin, Natural Resources Defense Council
To align with global efforts to limit warming to 1.5 degrees Celsius, the United States faces the monumental yet achievable task of cutting greenhouse gas (GHG) emissions to net zero no later than 2050. Even with last year’s historic climate legislation, the Inflation Reduction Act, the country is not on track to reach its climate goals. Doing so will require critical choices about how and where to invest economic, political, and social capital in the coming decades. Modeling by the authors is used to provide guidance on how to prioritize these choices by estimating the technology, infrastructure, and cost requirements of different pathways to net zero. The authors found that by deploying five crucial decarbonization strategies—clean power, energy efficiency, electrification, natural carbon solutions, and decarbonized fuels—achieving net zero GHG emissions in the United States can be technologically feasible and cost-effective. The first four decarbonization strategies capture the highest priority actions for getting the United States on track to net zero within this crucial decade.
The Carlyle Group’s Hidden Climate Impact: Exposing a decade of fossil fuel investments, Giachino et al., Private Equity Stakeholder Project, Global Energy Monitor, and Americans for Financial Reform Education Fund
Carlyle stands out among large diversified private equity firms as having one of the largest energy portfolios—most of it devoted to fossil fuels. The Carlyle Group’s lopsided energy portfolio has approximately $22.4 billion in carbon-based energy and $1.4 billion (less than 1 percent of assets under management) committed to renewable and sustainable energy companies. Exploiting regulatory exemptions and loopholes, private equity firms like Carlyle have become major greenhouse gas polluters, far away from public scrutiny and with minimal regulatory oversight. Private equity firms stand ready to swoop in and acquire polluting assets sold by publicly-listed companies under public and investor pressure to cut emissions from their operations. Furthermore, large institutional investors such as university endowments, philanthropic foundations, and public pension funds that have set ambitious decarbonization goals to mitigate climate risks in their portfolios are still heavily invested in private equity firms financing polluting assets. The authors find that Carlyle invested billions of dollars in fossil fuel assets which have dumped at least 277 million metric tons of CO2 and other greenhouse gasses into the atmosphere from 2011 to 2021, contributing to the global climate crisis, and harming low-income communities and communities of color disproportionately.
Human-induced climate change increased drought severity in Horn of Africa, Kimutai et al., World Weather Attribution
The southern part of the Horn of Africa, covering parts of southern Ethiopia, southern Somalia, and eastern Kenya saw below-average rainfall for the short rains (October-December) in 2020, 2021, and 2022 as well as the long rains (March-May) in 2021 and 2022. In order to identify whether human-induced climate change was a driver of the low rainfall, i.e. the meteorological drought, the authors analyzed rainfall over the most impacted region in the southern Horn of Africa, covering parts of southern Ethiopia, southern Somalia, and eastern Kenya, for 24 consecutive months, from January 2021 to December 2022, as well as just the individual 2022 March-May and October-December seasons separately. The authors found that in today’s climate, which has been warmed by about 1.2°C through human-induced greenhouse gas emissions, the below-average rainfall in the March-May season is a 1 in 10-year event, a 1 in-5-year event in the short rains. For the entire 24-month period there is a 5% chance every year for such an event to develop. The authors found that, as a result of human-induced climate change, the combination of low rainfall and high evapotranspiration as unusual as the recent conditions would not have led to drought at all in a 1.2°C cooler world. In today’s climate, the same event is now classified as exceptional drought, with major crop and pasture losses and widespread water shortages. This change in drought severity is primarily due to the strong increase in evaporative demand caused by higher temperatures. Climate change has made events like the current drought much stronger and more likely; a conservative estimate is that such droughts have become about 100 times more likely.
Laying the Foundation for New and Advanced Nuclear Reactors in the United States, National Academies of Sciences, Engineering, and Medicine
The world confronts an existential challenge in responding to climate change, resulting in an urgent need to reduce greenhouse gas emissions from all sectors of the economy. What will it take for new and advanced nuclear reactors to play a role in decarbonization? Nuclear power provides a significant portion of the world's low-carbon electricity, and advanced nuclear technologies have the potential to be smaller, safer, less expensive to build, and better integrated with the modern grid. However, if the United States wants advanced nuclear reactors to play a role in its plans for decarbonization, there are many key challenges that must be overcome at the technical, economic, and regulatory levels. The authors discuss how the United States could support the successful commercialization of advanced nuclear reactors with a set of near-term policies and practices. The authors recommend addressing the need to close technology research gaps, explore new business use cases, improve project management and construction, update regulations and security requirements, prioritize community engagement, strengthen the skilled workforce, and develop competitive financing options.
Pathways to Commercial Liftoff: Carbon Management, Fahs et al., Department of Energy
Today, the United States leads the world in carbon management deployment, with over 20 million tonnes of CO2 per annum (MTPA) of carbon capture capacity. But this is just 1 to 5 percent of what could be needed by 2050: the U.S. will likely need to capture and permanently store approximately 400 to 1,800 MTPA to meet its net-zero commitments by 2050. This scale-up represents a massive investment opportunity of up to approximately $100 billion by 2030 and $600 billion by 2050. A portfolio of carbon management technologies for a suite of applications is commercially mature and ready to deploy today. There are several dozen commercial-scale carbon management projects currently in operation and well over a hundred in stages of project development. The authors discuss the whole carbon management ecosystem, including point-source carbon capture, utilization, and storage (CCUS) and carbon dioxide removal technologies (CDR). The authors suggest that the industry is poised to allocate billions of dollars in capital towards carbon management technologies, driven by industries with attractive economics for CCUS, like ethanol, natural gas processing, ammonia, as well as other large integrated projects. This is enabled by the current supportive policy framework, partly based on recent changes from the Inflation Reduction Act. The United States also has excellent storage geology and relatively abundant low-cost zero-carbon energy resources that can power CDR projects.

With a median world income of US$ 9,373, for most of us US$ 42 is significant money to wager on an article's relevance and importance.
Most articles appearing here are found via RSS feeds from journal publishers, filtered by search terms to produce raw output for assessment of relevance.
Relevant articles are then queried against the Unpaywall database, to identify open access articles and expose useful metadata for articles appearing in the database.
The objective of New Research isn't to cast a tinge on scientific results, to color readers' impressions. Hence candidate articles are assessed via two metrics only:
A few journals offer public access to "preprint" versions of articles for which the review process is not yet complete. For some key journals this all the mention we'll see in RSS feeds, so we include such items in New Research. These are flagged as "preprint."
The section "Informed opinion, nudges & major initiatives" includes some items that are not scientific research per se but fall instead into the category of "perspectives," observations of implications of research findings, areas needing attention, etc.
Please let us know if you're aware of an article you think may be of interest for Skeptical Science research news, or if we've missed something that may be important. Send your input to Skeptical Science via our contact form.
A list of journals we cover may be found here. We welcome pointers to omissions, new journals etc.
