A cloudless sky on a sunny day looks featureless and inactive to our eyes. In reality, invisible to us a perfect frenzy of chemistry is happening in the daytime sky. For people interested in tracking the life history of a given compound in Earth's atmosphere there are many details to capture and account for.
In connection with climate change, we're of course interested in the effective residence time of the most important "greenhouse gases" or GHGs, which include not only CO2 but also methane (CH4) and nitrous oxide (N2O).
Methane is not only a much more potent GHG than CO2 but is also (and unlike CO2) chemically very busy in the atmosphere, too active and too generous for its own good. CH4's trip into the air is essentially on a one-way ticket; all methane entering the atmosphere is also ultimately destroyed there. Destruction mostly happens in interactions with OH and Cl radicals hungry for electrons on offer by CH4.
Careful accounting for availability of radicals is needed to predict the lifespan of methane in the atmosphere. Qinyi Li et al. have paid particular attention to the various roles of various compounds and elements acting in concert and opposition to act on and destroy methane, in Reactive halogens increase the global methane lifetime and radiative forcing in the 21st century (Nature Communications). In particular the authors note that the radical compound OH is a main "consumer" of methane, but OH itself requires O3 (ozone) as a feedstock. Full accounting reveals that O3 is destroyed in suffiicent quantity by halogens such as bromine, iodine and chlorine so as to limit the supply of OH radicals. This is a previously unidentified and hence unconsidered factor, and one that is quite significant. It helps to explain some discrepancies between modeled expectations and observed behavior.
The above atmospheric chemistry description is highly simplified and paraphrased by somebody who did their 3 semesters of university chemistry about 40 years ago. The upshot is pretty easy for all of us to understand. From the abstract:
Here, we demonstrate that reactive halogen chemistry increases the global CH4 lifetime by 6–9% during the 21st century. This effect arises from significant halogen-mediated decrease, mainly by iodine and bromine, in OH-driven CH4 loss that surpasses the direct Cl-induced CH4 sink. This increase in CH4 lifetime helps to reduce the gap between models and observations and results in a greater burden and radiative forcing during this century. The increase in CH4 burden due to halogens (up to 700 Tg or 8% by 2100) is equivalent to the observed atmospheric CH4 growth during the last three to four decades. Notably, the halogen-driven enhancement in CH4 radiative forcing is 0.05 W/m2 at present and is projected to increase in the future (0.06 W/m2 by 2100); such enhancement equals ~10% of present-day CH4 radiative forcing and one-third of N2O radiative forcing, the third-largest well-mixed greenhouse gas.
This isn't good news, especially when projected onto the weekly drumbeat of research findings on methane sources we're unleashing by our rapid warming, thawing and flooding of abundant organic carbon stocks, which when combined with hungry microorganisms will feed methane into our atmosphere in abundance.
Saudi Arabia’s Climate Change Policy and the Circular Carbon Economy Approach. Squaring a circle turns out to be quite difficult.
Mitigating climate disruption in time: A self-consistent approach for avoiding both near-term and long-term global warming. The authors argue and illustrate how optimal & fully predictable mitigation of climate change must include a holistic inventory of anthropogenic emissions— including those with offsetting effects. There are improvements to be made in the scope of our inventories & accounting.
A right to pollute versus a duty to mitigate: on the basis of emissions trading and carbon markets identifies fundamental moral failure in the concept of "cap and trade" as a means to steer ourselves to lower CO2 emissions. Moving on from philosophical principles, the author also discusses cap-and-trade's failure to perform in the face of human nature and the real world.
The turning point: A Global Summary. Leaving aside "intangibles" such as misery, extinctions etc., the authors find that our present course for 3°C of warming will result in loss of US$178 trillion in net present value terms over the next 50 years. Conversely, not acting as Homo bolidus will see us squarely in the black. In this week's government/NGO section and offered by professional pragmatists Deloitte.
All of the above open access and free to read. As usual, this week's edition of NR includes a juicy selection of government and NGO reports, directly accessible by clicking here.

2022 Summer Reliability Assessment, North American Reliability Corporation
The assessment identifies, assesses, and reports on areas of concern regarding the reliability of the North American BPS (bulk power system) for the 2022 summer season. In addition, the assessment presents peak electricity demand and supply changes as well as highlights any unique regional challenges or expected conditions that might impact the BPS.
Summer Energy Market and Reliability Assessment, 2022, Federal Energy Regulatory Commission
The assessment provides the Federal Energy Regulatory Commission’s outlook for energy markets and electric reliability, focusing on June, July, August, and September 2022. The report contains four main sections. The first section discusses the findings of the Summer Assessment. The second section details the weather outlook for Summer 2022. The third section discusses energy market fundamentals, including natural gas and electric market supply and demand expectations, including expected North American Electric Reliability Corporation regional resource adequacy details. The fourth section describes notable issues and addresses potential implications of pipeline outages, drought, hydro-generation, and wildfires on western U.S. energy markets.
Energy Transition in PJM: Emerging Characteristics of a Decarbonizing Grid, PJM
Driven by PJM’s strategic pillars – facilitating decarbonization reliably and cost-effectively, planning/operating the grid of the future, and fostering innovation – PJM has embarked on a multiphase, multiyear effort to study the potential impacts associated with the evolving resource mix. The diverse set of PJM state policies were synthesized into three scenarios in which an increasing amount of the annual energy is served by carbon-free generation (40%, 50% and 70%). The assumptions embedded in the three scenarios – Base, Policy and Accelerated – were refined and extended in order to analyze the impact of four major sensitivities: electrification (electric vehicles and heating), energy storage, interregional interchange and the inclusion of a downward-sloping Operating Reserve Demand Curve into the energy and ancillary services markets. An entire year of the energy market was simulated with an hourly resolution, and the capacity contributions of renewable resources were evaluated using the Effective Load Carrying Capability method. The results suggest five key focus areas for the PJM stakeholder community and delineate the subsequent phases of the study: (1) electrification shifts the seasonal resource adequacy risk to winter; (2) retail rate design and energy storage become increasingly important with electrification; (3) market reforms are needed to incentivize flexibility and mitigate uncertainty; (4) the integration of renewable resources increases the need for balancing resources to meet forecasted ramping requirements; and (5) energy storage (four hours) enhances operational flexibility, but seasonal capacity and energy constraints require transmission expansion, long-term storage and other emerging technology.
Alaska Native Issues. Federal Agencies Could Enhance Support for Native Village Efforts to Address Environmental Threats, US Government Accountability Office
The Government Accountability Office (GAO) was asked to review federal efforts to help Alaska Native villages address environmental threats. The report examines (1) information about environmental threats to Native villages; (2) federal funding provided to address such threats, and actions supported by that funding; and (3) opportunities to better support efforts to build resilience to such threats. More than 70 out of over 200 Alaska Native villages face significant environmental threats from erosion, flooding, or thawing permafrost, according to a 2019 statewide assessment. Consequences from even a moderate flood or increasing erosion could be significant and over one-third of these communities face the compounding effects of more than one threat. According to several federal officials, short-term actions are needed to address the most urgent threats without waiting for additional studies. At the same time, many Native villages also need more information to support longer-term planning. Congress should consider establishing a coordinating entity to assist Native villages facing environmental threats.
Morocco, Algeria, Egypt: Assessing EU plans to import hydrogen from North Africa, Michael Barnard,
Corporate Europe Observatory and Transnational Institute
The European Commission’s 2020 hydrogen strategy has a big focus on importing ‘green’ renewables-based hydrogen from its neighborhood (North Africa and Ukraine). Since the recent invasion of Ukraine and the subsequent need to reduce dependency on Russian gas, the Europena Union (EU) has doubled its import targets to 10 million tonnes per year by 2030, as per the RePowerEU communiqué. The author examines three North African countries that in recent years are increasingly focused on hydrogen, based in significant part on the interest of the EU and its corporations. Morocco, Algeria and Egypt are all planning to manufacture green hydrogen and hydrogen-based products and ship them to the EU via boats and pipelines, to help meet this projected demand. The author examines how feasible is such a plan, how much would it cost, and would they be the best use of renewables in those countries? There are big question marks over whether green hydrogen can ever be exported at sufficiently attractive prices, given the high production and transportation costs.
The Carbon Bankroll. The Climate Impact and Untapped Power of Corporate Cash, Climate Safe Lending Network, The Outdoor Policy Outfit, and BankFWD
The research presented in the report makes it possible to calculate the emissions generated by a company’s cash and investments (cash, cash equivalents, and marketable securities). This research shows that this previously hidden emissions source is substantial. For some of the world’s largest companies, including Alphabet, Meta, Microsoft, and Salesforce, their cash and investments are their largest source of emissions. In fact, for Alphabet, Meta, and PayPal, the emissions generated by their cash and investments (financed emissions) exceed all their other emissions combined. The authors selected the companies featured in the report to show the magnitude of corporate cash and investment emissions and to highlight how companies’ climate accomplishments are being undermined by a misaligned financial system that is channeling hundreds of billions of corporate U.S. dollars into the carbon-intensive sectors driving the climate crisis.
Environment of Peace. Security in a new era of risk, Dabelko et al., Stockholm International Peace Research Institute
Two cataclysmic events have shaken our world in the space of just three years. The most serious pandemic in living memory has claimed millions of lives, sickened countless more people and caused economic damage measured in trillions of dollars. Now, Russia’s invasion of Ukraine has killed many thousands and created millions of refugees; it threatens to wreak havoc in the world’s food supply, raises the specter of nuclear conflict to a level not seen since the end of the cold war, and has raised questions anew over institutions designed to secure peace in Europe and globally. What does environmental degradation have to do with peace and security? The evidence assembled for this report shows that the answer is: everything. The twin security and environmental crises are linked in ways that we are only beginning to understand, with impacts we are only beginning to feel. Climate change is a risk multiplier for both new and pre-existing sources of tension. The impacts fall hardest in places already marked by poverty, dysfunctional governance and conflict history. But given the extent of interconnections in the 21st century, they have consequences right across the world—connecting people and populations in an environment of insecurity. There are three principal conclusions from the report. First, there is a profound need to begin anticipating and managing the increasing risks to peace stemming from the interlinked security and environmental crises. Second, that without a step change in action on all aspects of environmental degradation—cutting greenhouse gas emissions, reducing pollution, arresting the decline in species and ecosystems, and more—the security challenge will inevitably get worse. The third conclusion is that there is hope. Humanity has the knowledge and skills to escape from the trouble in which we find ourselves.
Russia Sanctions and Gas Price Crisis Reveal Danger of Investing in “Blue” Hydrogen, Jaller-Makarewicz et al., Institute for Energy Economics and Financial Analysis
Elevated gas prices and a future tight market means blue hydrogen, e.g., hydrogen derived from methane with carbon capture and storage, is no longer a low-cost solution. The authors estimate that blue hydrogen costs published by the UK government last year are now 36% higher, calling into question continued policy support for development of the technology. Blue hydrogen is an extension of the gas value chain and does not make sense as an investment during a gas price crisis.
The turning point. A Global Summary, Philip, Ibrahim & Hodges, Deloitte Economics Institute
The authors modeled region-level data from 15 geographies5 across Asia Pacific, Europe, and the Americas to estimate how much it could cost the global economy if we are not able to prevent global average temperatures from rising 3°C by the end of the century. Using scenario analysis which demonstrates how climate impacts could affect economic output (GDP), employment, and industry, the researchers established a new economic baseline, one that incorporates the climate impacts from a recent IPCC report. The authors then compared this three-degrees-hotter world to a more hopeful scenario: a future in which the world makes a different choice—and changes. The status quo is the costlier choice. According to the modeling, unchecked climate change could cost the global economy US$178 trillion in net present value terms from 2021–2070. The human costs would be far greater: a lack of food and water, a loss of jobs, worsening health and well-being, and reduced standard of living. If, on the other hand, the world acts now to rapidly achieve net-zero emissions by midcentury, the transformation of the economy could set the world up for stronger economic growth by 2070, according to the analysis. Such a transformation could increase the size of the world economy by US$43 trillion in net present value terms from 2021–2070.
We know it's frustrating that many articles we cite here are not free to read. One-off paid access fees are generally astronomically priced, suitable for such as "On a Heuristic Point of View Concerning the Production and Transformation of Light" but not as a gamble on unknowns. With a median world income of US$ 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.
