The United States experienced some historical low temperature records during the just-concluded winter. It's a reminder that climate and weather are quite noisy; with regard to our warming climate,, as with a road ascending a mountain range we may steadily change our conditions but with lots of variation on our path. Despite what we've just seen, the probability of new low temperature records being set in North America is steadily shrinking. Zhenyuan Cui & Chao He quantify one such measure in their paper Decadal trend of synoptic temperature variability over the Northern Hemisphere in winter. Rapid cooling events or "RCEs" are becoming rarer and of smaller magnitude: "The synoptic-scale standard deviation of temperature decreases significantly with a trend of − 0.15 K/decade (− 0.09 to − 0.21 K/decade among reanalysis datasets) over continental regions in mid-high latitudes. Correspondingly, the rapid cooling events (RCEs), defined based on the day-to-day temperature decrease exceeding 6 K, also show a general decreasing trend in terms of their frequency and intensity."
Meanwhile, the Gulf of Mexico (GOM) is accruing energy at a prodigious rate. Zhankun Wang et al. publishing in the AMS Journal of Climate report energy being stuffed into this patch of ocean at a rate of "approximately 1.38 ± 0.41 TW for the entire water column of the GOM between 1970 and 2020. The rate has not been continuous; more lately energy input to the GOM is about 1.76 ± 1.36 TW. The team's entire careful analysis can be read in their article Upper-Oceanic Warming in the Gulf of Mexico between 1950 and 2020.
Simulated carbon cycle and Earth system response to atmospheric CO2 removal by Cao, Jin and Jiang reports on an improvedd, more holistic exploration of CO2 removal at large scale: "We expanded previous studies by using an Earth system model to examine the response of land and ocean carbon cycle, as well as a set of climate variables to idealized scenarios of atmospheric CO2 removal with different removal rates." The authors thereby identify a range of effects probably obvious for experts but not so much to the rest of us. They conclude: Our study demonstrates that to offset previous positive CO2 emissions by atmospheric CO2 removal does not mean to offset climate consequence of positive CO2 emissions. Rapid and deep reduction in CO2 emissions is key to prevent and limit increasing risks from further warming.
Looking ahead to more peaceful future in Ukraine and how to deal with the aftermath of Russia's invasion and its accompanying destruction of the built environment on a massive scale, in their perspective piece for PLOSClimate Kateryna Utkina, Ilona Otto & Galina Churkina point out that Ukraine is rich in biomass raw materials. This leads to an opportunity: "Since the construction industry is one of the largest sources of greenhouse gas emissions (GHG), and the lifespan of buildings and infrastructure extends beyond 50 years, it is essential to include net-zero climate targets in the post-war reconstruction. One possible step that can be taken to meet the climate policy goals is to use construction materials, where the manufacturing and use have a balancing effect the GHG emissions. These construction materials store carbon, and their manufacturing is associated with low GHG emissions." The authors suggest key steps for making low-impact reconstruction possible, in Rebuild better for a sustainable future
From this week's government/NGO section, "ahem" delivered in An Economist’s Case for Restrictive Supply Side Policies. Ten Policies to Manage the Fossil Fuel Transition: "The authors explain the economic rationale—and climate necessity—of deploying restrictive supply-side policies to actively wind down fossil fuel extraction. Levers like bans, restrictions, or phaseouts are not new; in fact, history shows that products can go quickly from commonplace to banned. In the last four decades, the United States has outlawed lead paint, phased out asbestos, and curtailed tobacco marketing and sales. Similar policies can be used for fossil fuels; indeed, comparable policies are in place in other countries and at the state level."

Evaluating Impacts of the Inflation Reduction Act and Bipartisan Infrastructure Law on the U.S. Power System, Steinberg, National Renewable Energy Laboratory
The authors present the methods and results of a study estimating the potential impacts of key provisions of the Inflation Reduction Act (IRA) and the Bipartisan Infrastructure Law (BIL) on the contiguous U.S. power sector from the present through 2030. The analysis uses an advanced power system planning model, the Regional Energy Deployment System (ReEDS), to evaluate how major provisions from both laws affect investment in and operation of utility-scale generation, storage, and transmission, and, in turn, how those changes impact power system costs, emissions, and climate and health damages. While not exhaustive in capturing every provision, the analysis estimates the possible scale of power sector effects that could result from the modeled provisions in IRA and BI
Innovation at Scale: Supporting Pilot-Scale Demonstrations, Natalie Tham, Bipartisan Policy Center
The establishment of the Office of Clean Energy Demonstrations (OCED) at the Department of Energy represents an important step toward accelerating American innovation and achieving net-zero greenhouse gas (GHG) emissions by 2050. The clean energy and low-emissions solutions required to meet these goals are complex, capital-intensive, and not yet deployed at scale. Promising technologies often fail to move past successful research and development (R&D) into market adoption due to the expensive and risky nature of validating technology at scale. Federal funding provided by OCED is critical to effectively demonstrate and de-risk these technologies so they may be commercially proven and deployed widely. While OCED programs have and likely will continue to focus on very large and complex projects—those at the last step before commercial application or requiring $25 million or more to achieve commercial scale—there is a lack of public and private funding for pilot-scale demonstrations which require less than $25 million. Projects at this stage are larger than typical venture capital investments but not yet sufficiently de-risked for project finance providers. Pilot-scale demonstrations aim to prove that larger investments are worthwhile. OCED is well-positioned to address this funding support gap by creating a Small Business Innovation Research (SBIR) program and a Small Business Technology Transfer (STTR) program through existing authority.
The role of climate change in extreme rainfall associated with Cyclone Gabrielle over Aotearoa New Zealand’s East Coast, Harrington et al, World Weather Attribution
n early February 2023, a tropical low-pressure system formed in the Pacific Ocean to the north of Fiji before slowly moving westwards into the Coral Sea. A cyclone subsequently formed in the open oceans to the south of the Solomon Islands where, surrounded by sea surface temperatures much warmer than normal (approaching 30°C), both oceanic and atmospheric conditions were favorable for the system to intensify. Tropical Cyclone Gabrielle was officially named by the Australian Bureau of Meteorology on February 8th, strengthening to its peak Category 3 status on February 10th. Based on extrapolations from weather records that go back to 1979, heavy rain like that recorded over two days was about 30% more intense and four times more likely than in a pre-warming world that is 2.1 degrees Fahrenheit (1.2 degrees Celsius) cooler than now. But there are large uncertainties in those figures because available data are limited.
An Economist’s Case for Restrictive Supply Side Policies. Ten Policies to Manage the Fossil Fuel Transition, Mark Paul and Lina Moe, Climate and Community Project
The authors explain the economic rationale—and climate necessity—of deploying restrictive supply-side policies to actively wind down fossil fuel extraction. Levers like bans, restrictions, or phaseouts are not new; in fact, history shows that products can go quickly from commonplace to banned. In the last four decades, the United States has outlawed lead paint, phased out asbestos, and curtailed tobacco marketing and sales. Similar policies can be used for fossil fuels; indeed, comparable policies are in place in other countries and at the state level. The International Energy Agency has made it clear: If the planet is to remain habitable, fossil fuel extraction must end. Restrictive supply-side interventions can provide crucial support for demand-side policies by guaranteeing emission reductions, stopping international carbon leaks, and alleviating carbon lock-in. Complementary supply-side policy strategies crucial to achieving the United States’ decarbonization goals include ending fossil fuel subsidies, banning new leases and permits for fossil fuel extraction on federal lands and in federal waters, rejecting all new fossil fuel infrastructure, tax windfall profits, ban oil and fossil gas exports, and nationalize the fossil fuel industry.
Our Progress Towards Net Zero, Shell
Reduced Scope 1 and 2 absolute emissions by 30%. Reduced net carbon intensity by 3.8%. Invested $4.3 billion in low-carbon energy solutions, and $3.9 billion in non-energy products. Developing renewable hydrogen. To account for reductions in emissions across full energy value chains it is necessary to build new protocols to include mitigation actions by both energy suppliers and users. Currently, energy suppliers report Scope 3 emissions from the use of their products, which are equivalent to the Scope 1 emissions reported by the users of those products. However, when users of energy products mitigate their Scope 1 emissions by the use of carbon capture and storage or offsets there is no protocol for reflecting a corresponding reduction in Scope 3 emissions reported by the energy supplier. Shell will continue to engage stakeholders on these carbon protocols and will seek to align with new frameworks as they evolve.
Triple Threat. How disease, climate risks, and unsafe water, sanitation and hygiene create a deadly combination for children, United Nations Children’s Fund
Globally, 600 million children still lack safely managed drinking water, 1.1 billion lack safely managed sanitation and 689 million lack basic hygiene services, 149 million children still face the indignity of practicing open defecation and unsafe water, sanitation and hygiene (WASH) are still responsible for the deaths of around 1,000 children under 5 every day. The authors examine the “triple burden” of water, sanitation, and hygiene (WASH)-related threats facing children at the intersection of access to WASH services, the burden of WASH-related diseases, and climate threats. By examining the burden of disease from unsafe WASH, people can see where the problem is greatest. Through examining access to water and sanitation services, people can see where investment is the lowest. Through examining climate threats, people can see which countries face the greatest risk to both health and services for children. Ten countries alone – with a combined population of over 190 million children and all in sub-Saharan Africa – face this triple burden. Around 2 out of 5 deaths from unsafe WASH are concentrated in these countries.
Cover Image Review of the Draft Fifth National Climate Assessment, National Academies of Sciences, Engineering, and Medicine
The US Global Change Research Program (USGCRP) is mandated to develop an assessment of global change every four years or less. The Fifth National Climate Assessment (NCA5) is the latest in a series of sustained assessments that evaluate the state of global change science and analyze the wide range of impacts of climate change in the United States. The assessments represent a consensus-based view of the state of knowledge, relevant for policy and decision making.
Review of the Draft Fifth National Climate Assessment, National Academies of Sciences, Engineering, and Medicine
The U.S. Global Change Research Program (USGCRP) is mandated to develop an assessment of global change every four years or less. The Fifth National Climate Assessment (NCA5) is the latest in a series of sustained assessments that evaluate the state of global change science and analyze the wide range of impacts of climate change in the United States. The assessments represent a consensus-based view of the state of knowledge, relevant for policy and decision-making. The draft NCA5 report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being to the built environment, to businesses and economies, and to ecosystems and water resources.
The Future of Gas in New York State, Michael Walsh and Michael Bloomberg, Building Decarbonization Coalition
The authors provide information to assist the Public Service Commission and other stakeholders at this critical, early moment in gas distribution system transition planning. They use existing research and add new data and analysis on several key topics, such as the costs of the gas distribution system, the fragility of gas utility business models to competition from new electric technologies, the hurdles to substituting fuels like renewable natural gas (RNG) or hydrogen for fossil methane gas, and the benefits and pitfalls of pathways studies. The authors offer a synthesis of these and other factors in a scenario-based discussion of potential approaches to gas distribution system transition.
Zero Emission Long-Haul Heavy-Duty Trucking, Thomas Walker III, Clean Air Task Force
The author compared the operational performance of hydrogen fuel cell vehicles (FCEV) and battery electric vehicles (BEV), identifying key advantages to FCEVs in efforts to decarbonize long–haul heavy-duty trucking. The author used a novel approach to analyzing questions of cost by comparing the operational performance of BEV and FCEV drive trains and infrastructure as alternatives to diesel trucking on a popular long-haul route in the U.S. The author found that FCEVs outperform BEVs in terms of the number of stops required (three vs. eight), total time spent refueling (1.4 hours vs. 43.8 hours), and available room for cargo (accounting for the size of equipment). While building charging and refueling infrastructure for BEVs and FCEVs could prove equally challenging, FCEV refueling technology has the comparative advantage of being similar to existing diesel refueling technology, making for fewer barriers to transition.
The Impact of Resource Inflexibility on Capacity Accreditation in New England, Frost et al., Synapse Energy Economics
The authors analyze the operational limitations of several electrical generation resources in New England. They examined the risk of unpredicted scarcity events that could be impacted by unplanned outages and forecast errors. They found that electrical generation resources can take long amounts of time to start up in New England and that within these long start-up periods, there is a considerable risk of forecast error or forced outages that push the electrical system into shortage before long start-up time units can respond. While the analysis focused on several specific resources, the problems that were identified are widespread.
Chapter 9, Opportunities for Better Managing Weather Risk in the Changing Climate, Economic Report of the President, The Council of Economic Advisers
The risks that climate change poses are multidimensional, regionally specific, and vary based on underlying socioeconomic vulnerabilities. Adaptation policies need to be targeted to particular settings and therefore will need to be both varied and complex. The authors proposes four overarching objectives for structuring further Federal adaptation efforts including producing and disseminating knowledge about climate risk; long-term planning for the climate transition; ensuring accurate pricing of climate risks; and protecting the vulnerable.
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.
A list of journals we cover may be found here. We welcome pointers to omissions, new journals etc.
