From our government/NGO reports section, World Weather Attribution's latest report Extreme heat in North America, Europe and China in July 2023 made much more likely by climate change:
North America, Europe, and China have experienced heatwaves increasingly frequently over the last years as a result of warming caused by human activities, hence the current heat waves are not rare in today’s climate with an event like the currently expected approximately once every 15 years in the US/Mexico region, once every 10 years in southern Europe, and once in 5 years for China. Without human-induced climate change, these heat events would however have been extremely rare. In China, it would have been about a 1 in 250-year event while maximum heat like in July 2023 would have been virtually impossible to occur in the U.S./Mexico region and southern Europe if humans had not warmed the planet by burning fossil fuels.
In Climate Risk Management, Further understanding “severe” climate risk:
Acknowledging that the notion of dangerousness can substantially vary from one sociocultural context to another, this Perspective paper builds on recent literature to explore three notions that are estimated to be foundational to climate risk severity: the physical, ecological and social thresholds leading to transformational and possibly abrupt changes; the irreversibility of these changes; and the cascading effects within and across the systems affected. While not necessarily the most determining dimensions of risk, they deserve more attention and integration into frameworks to assess “severe” climate risk, such frameworks remaining under-developed.
Growing Threats From Swings Between Hot and Wet Extremes in a Warmer World, Geophysical Research Letters:
In this study, we present a comprehensive assessment of the two types of interacting hot and wet extremes: humid heat extremes followed by pluvial flooding (heat-pluvial) and extreme pluvials followed by humid heat (pluvial-heat). We find that these events have increased significantly in most regions of the world for the last three decades, which can be associated with the warming effect. Importantly, we identify that the vapor pressure deficit plays an important but varying role in the abrupt alternation between heat and pluvial events. We emphasize the importance of using reliable statistical tests to ensure the validity of the results for complex compound events. Our analysis highlights the need for policymakers and stakeholders to develop adaptation strategies to cope with overlapping vulnerabilities due to compound hot and wet extremes, especially in areas prone to both such as West Australia, South America and Sub-Saharan Africa.
Deglacial perspectives of future sea level for Singapore, Nature Communications Earth & Environment:
Here we provide probability perspectives of future sea level for Singapore using regional geological reconstructions and instrumental records since the last glacial maximum ~21.5 thousand years ago. We quantify magnitudes and rates of sea-level change showing deglacial sea level rose from ~121 m below present level and increased at averaged rates up to ~15 mm/yr, which reduced the paleogeographic landscape by ~2.3 million km2. Projections under a moderate emissions scenario show sea level rising 0.95 m at a rate of 7.3 mm/yr by 2150 which has only been exceeded (at least 99% probability) during rapid ice mass loss events ~14.5 and ~9 thousand years ago. Projections under a high emissions scenario incorporating low confidence ice-sheet processes, however, have no precedent during the last deglaciation.

New Mexico Advanced Clean Cars II Program, Tolomiczenko et al., Natural Resources Defense Council, Sierra Club, and Western Resource Advocates
The authors investigated the state adopting the Advanced Clean Cars II (ACC II) regulation under two different manufacturer compliance scenarios including manufacturers, as expected, use many of their compliance flexibilities to comply with the regulation or manufacturers do not use these flexibilities to meet compliance. These two compliance strategies provide, respectively, a reasonable midpoint estimate and an upper limit of zero-emission vehicle (ZEV) placements under ACC II policy. The authors also investigated the effect of New Mexico reaching 100 percent clean electricity by 2040 under both ACC II compliance scenarios. Depending on the scenario chosen, the ACC II regulation will have significant cumulative net societal benefits through 2050.
A Path to Pollution-Free Buildings: Meeting Xcel's 2030 Gas Decarbonization Goals, Fickling et al., Natural Resources Defense Council and the Southwest Energy Efficiency Project
In 2021, Colorado passed legislation requiring Colorado’s gas utilities to reduce their greenhouse gas emissions by 4% by 2025 and 22% by 2030, relative to 2015 levels. These goals cover emissions from customers’ use of gas and leakage from the utility’s distribution system. They are ambitious, and the steady growth in gas sales by Xcel Energy, Colorado’s largest electricity and gas provider, makes them even more so. Since 2015, Xcel’s retail gas sales have grown by 9%, meaning that the utility’s 2030 emissions reduction goal is really a 28% reduction from current levels – which it must achieve in just seven years. The authors recommend measures to drive a steep reduction in emissions from the gas utility and demonstrate how Xcel can meet Colorado’s targets in a way that delivers the most emissions reductions per ratepayer dollar. To achieve its 2030 goal, Xcel must rapidly increase adoption of efficient electric appliances – heat pumps and heat pump water heaters – and weatherize tens of thousands of homes and businesses. While the efforts necessary to meet the clean heat targets are challenging, they are achievable.
The Prospects for Pumped Storage Hydropower in Alaska, Koritarov et al., Argonne National Laboratory and hte National Renewable Energy Laboratory
The resource mapping analysis confirmed that numerous locations in Alaska are suitable for the development of pumped storage hydropower (PSH) projects, both larger grid scale projects and smaller projects that could be suitable for remote communities. The resource assessment for larger, grid-scale projects showed the potential for more than 1,800 closed-loop systems in Alaska, with a total energy storage capacity of about 4 terawatt hours (TWh). Because of their small reservoir sizes and dam heights, many locations were identified as potentially suitable for small-scale PSH systems. Nearly 50% of the identified potentially suitable small-scale PSH sites are in Southeast Alaska.
Hawai'i Pathways to Net Zero: An Initial Assessment of Decarbonization Scenarios, Gold-Parker et al., Hawaiian Electric
The authors developed long-term, economywide decarbonization scenarios that meet Hawaii's 2045 net zero greenhouse has target. Importantly, this study does not seek to define prescriptive approaches to achieving net zero in Hawaii, but rather provides an initial exploration of what might be needed to achieve this ambitious climate goal in terms of energy infrastructure, technology adoption and deployment, and supportive policies. This initial assessment of decarbonization scenarios does not include an evaluation of the potential costs and benefits of the energy transition, focusing instead on the scale of the energy transition and the types of technologies and fuels that would be needed to meet Hawaii’s 2045 target.
FEMA Response and Recovery Climate Change Planning Guidance, Federal Emergency Management Agency
The authors provide background information on climate change and how it affects emergency management operations. They also provide steps and considerations to incorporate that information into existing planning processes and products. The intended audience for this climate change guidance document includes all internal FEMA response and recovery planners. This guidance provides an overview of climate change and general insights from climate assessments on observed climate-related impacts; input regarding how FEMA should expand its threat/hazard profiles based on climate change trends and predictions; and climate change planning considerations to inform FEMA’s deliberate plans for federal emergency response and recovery operations.
Modelling Climate Litigation Risk for (Re)Insurers, Martin Lockman, Sabin Center for Climate Change Law
"Modelling Climate Litigation Risk for (Re)Insurers" assembles a toolkit to help academics, attorneys, insurance practitioners, and industry regulators model (re)insurer climate litigation risk. Section 2 of this report discusses the categories of climate litigation, and creates a definition of “climate litigation risk” tailored towards (re)insurer risk evaluation. Using this definition, Section 3 next systematically categorizes the risks, commercial opportunities, and operational flexibility that climate litigation presents to (re)insurers. Section 4 then discusses qualitative and quantitative techniques used to model these climate litigation risks, and outlines a simple climate litigation risk model for (re)insurers. Finally, annexes to this report (1) review regulations that require companies to assess and disclose their exposure to climate litigation; (2) outline key academic, industry, and government resources that discuss climate litigation risks and opportunities for insurers; and (3) highlight global climate litigation of particular significance to (re)insurers.
Extreme heat in North America, Europe and China in July 2023 made much more likely by climate change, Zachariah et al., World Weather Attribution
July 2023 saw extreme heatwaves in several parts of the Northern Hemisphere, including the U.S. southwest, Mexico, southern Europe, and China. The authors assess to what extent human-induced climate change altered the likelihood and intensity of the extreme July heat in these regions. In line with what has been expected from past climate projections, these events are not rare anymore. North America, Europe, and China have experienced heatwaves increasingly frequently over the last years as a result of warming caused by human activities, hence the current heat waves are not rare in today’s climate with an event like the currently expected approximately once every 15 years in the US/Mexico region, once every 10 years in southern Europe, and once in 5 years for China. Without human-induced climate change, these heat events would however have been extremely rare. In China, it would have been about a 1 in 250-year event while maximum heat like in July 2023 would have been virtually impossible to occur in the U.S./Mexico region and southern Europe if humans had not warmed the planet by burning fossil fuels. In all the regions a heatwave of the same likelihood as the one observed today would have been significantly cooler in a world without climate change.
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.
