The New Climate Denial, The Center for Countering Digital Hate
The authors quantify the startling and important rise over the past five years in what they call “New Denial” — the departure from rejection of anthropogenic climate change, to attacks on climate science and scientists, and rhetoric seeking to undermine confidence in solutions to climate change. “New Denial” claims now constitute 70% of all climate denial claims made on YouTube, up from 35% six years ago. The study centers on data analysis performed by an AI tool, CARDS, developed by academics Travis G. Coan, Constantine Boussalis, John Cook, and Mirjam O. Nanko. The AI allowed the authors to quantify the frequency of different types of climate denialist claims in text. The authors identified the changing tactics of climate deniers on YouTube by analyzing thousands of hours of transcripts of videos on the platform from 96 channels dating back to 2018.

Acceleration of the ocean warming from 1961 to 2022 unveiled by large-ensemble reanalyses, Storto & Yang, Nature Communications:
OHC [ocean heat content] increases heavily threaten the marine environment, therefore, reconstructing OHC before the well-instrumented period (i.e., before the Argo floats deployment in the mid-2000s) is crucial to understanding the multi-decadal climate change in the ocean. Here, we shed light on ocean warming and its uncertainty for the 1961-2022 period through a large ensemble reanalysis system that spans the major sources of uncertainties. Results indicate a 62-year warming of 0.43 ± 0.08 W m−2, and a statistically significant acceleration rate equal to 0.15 ± 0.04 W m−2 dec−1, locally peaking at high latitudes. The 11.6% of the global ocean area reaches the maximum yearly OHC in 2022, almost doubling any previous year.
Climate change is rapidly deteriorating the climatic signal in Svalbard glaciers, Spolaor et al., The Cryosphere:
The Svalbard archipelago is particularly sensitive to climate change due to the relatively low altitude of its main ice fields and its geographical location in the higher North Atlantic, where the effect of Arctic amplification is more significant. The largest temperature increases have been observed during winter, but increasing summer temperatures, above the melting point, have led to increased glacier melt. Here, we evaluate the impact of this increased melt on the preservation of the oxygen isotope (δ18O) signal in firn records. δ18O is commonly used as a proxy for past atmospheric temperature reconstructions, and, when preserved, it is a crucial parameter to date and align ice cores. By comparing four different firn cores collected in 2012, 2015, 2017 and 2019 at the top of the Holtedahlfonna ice field (1100 m a.s.l.), we show a progressive deterioration of the isotope signal, and we link its degradation to the increased occurrence and intensity of melt events.
Evidence of human influence on Northern Hemisphere snow loss, Gottlieb & Mankin, Nature
Here we show that human-caused warming has caused declines in Northern Hemisphere-scale March snowpack over the 1981–2020 period. Using an ensemble of snowpack reconstructions, we identify robust snow trends in 82 out of 169 major Northern Hemisphere river basins, 31 of which we can confidently attribute to human influence. Most crucially, we show a generalizable and highly nonlinear temperature sensitivity of snowpack, in which snow becomes marginally more sensitive to one degree Celsius of warming as climatological winter temperatures exceed minus eight degrees Celsius. Such nonlinearity explains the lack of widespread snow loss so far and augurs much sharper declines and water security risks in the most populous basins.
Functional changes across marine habitats due to ocean acidification, Teixidó et al., Global Change Biology:
Here we quantify shifts in species composition and trait diversity associated with ocean acidification (OA) by using field measurements at marine CO2 vent systems spanning four reef habitats across different depths in a temperate coastal ecosystem. We find that both species and trait diversity decreased, and that ecosystem properties (understood as the interplay between species, traits, and ecosystem function) shifted with acidification. Furthermore, shifts in trait categories such as autotrophs, filter feeders, herbivores, and habitat-forming species were habitat-specific, indicating that OA may produce divergent responses across habitats and depths.
The role of flexible geothermal power in decarbonized electricity systems, Ricks et al., Nature Energy:
In this work we evaluate the impact of operational flexibility on the long-run system value and deployment potential of EGS [enhanced geothermal systems] power in the western United States. We find that load-following generation and in-reservoir energy storage enhance the role of EGS power in least-cost decarbonized electricity systems, substantially increasing optimal geothermal penetration and reducing bulk electricity supply costs compared to systems with inflexible EGSs or no EGSs. Flexible geothermal plants preferentially displace the most expensive competing resources by shifting their generation on diurnal and seasonal timescales, with round-trip energy storage efficiencies of 59–93%. Benefits of EGS flexibility are robust across a range of electricity market and geothermal technology development scenarios.
The perceived potential of religion in mitigating climate change and how this is being realized in Germany and Switzerland, Hearn et al., Journal of Environmental Studies and Sciences:
This article examines the perceived potential of religion in mitigating climate change and how this is being realized. Based on 38 interviews, conducted with representatives from religious communities and umbrella organizations in Germany and Switzerland, we focus on the areas of values, political influence, and materialization. Our results show that the potential of religion in addressing climate change remains largely unfulfilled despite increasing steps in this direction.
Global Impact of Sea Level Rise on Coastal Fresh Groundwater Resources, Zamrsky et al., Earth's Future
Here, we assess the impact of sea level rise exclusively on coastal fresh groundwater resources worldwide (limited to areas with unconsolidated sedimentary systems) by estimating future decline in inland fresh groundwater volumes under three sea level rise scenarios following Representative Concentration Pathway (RCP) 2.6, 4.5, and 8.5. For that, 2D groundwater models in 1,200 coastal regions estimate the past, present and future groundwater salinity. Our results show that roughly 60 (range 16–96) million people living within 10 km from current coastline could lose more than 5% of their fresh groundwater resources by 2100 according to RCP 8.5 scenario compared to only 8 (range 0–50) million people based on RCP 2.6 scenario.
Job creation in a low carbon transition to renewables and energy efficiency: a review of international evidence, Hanna et al., Sustainability Science
In this paper, we present findings from a systematic review on job creation, quality, and skills, focusing on decarbonisation in the energy sector. We compare a range of gross job employment factors which indicate that overall, investment in renewable energy and energy efficiency can deliver more jobs than gas or coal power generation. In addition, we review a subset of recent studies which estimate the net employment effects of decarbonisation in the energy sector at a national scale, across various international contexts. These national studies largely agree that the most likely outcome over the next few decades is a modest net positive creation of jobs and moderate economic growth.

Transforming Energy Demand, Daniel Gross and Matthew Yeomans, World Economic Forum and PwC
The authors outline actions for businesses and countries to enhance energy management, efficiency, and carbon intensity reduction. they highlight commercially beneficial levers, implementable with existing technologies, to affect the transition significantly. Adopting measures for energy-efficient output and service delivery is essential for businesses and countries to sustain economic growth and achieve net-zero goals. As the global population and energy demand rise, particularly in developing markets, implementing public policies and fostering value chain collaborations are key to managing energy consumption and reducing carbon intensity. This will help mitigate energy costs and supply issues and unlock commercial benefits, thereby accelerating the transition. At COP28, over 120 countries committed to doubling the pace of energy efficiency improvement, necessitating concrete, realistic plans.
Global Water Monitor 2023 Summary Report, Van Dijk et al., Global Water Monitor
The authors provide rapid and global information on climate and water resources through information on rainfall, air temperature, humidity, soil and groundwater conditions, vegetation access to water, river flows, flooding, and lake volumes in 2023. Trends in the water cycle and some of the most important hydrological events of 2023 are interpreted and discussed. For example in 2023, precipitation was close to average. There does not appear to be a clear trend toward more monthly high or low rainfall extremes. The average temperature was the highest recorded globally and in 77 countries. The frequency of record-warm months was also the highest 0bserved. Relative air humidity was the second lowest on record, continuing a trend towards drier average and extreme conditions. Drier-than-normal conditions prevailed nearly everywhere. Despite warmer and drier conditions, high annual soil water conditions were observed in many regions. Vegetation vigor was the highest since 2001, continuing a steady increase over the last decades. Surface water occurrence from water bodies and flood events was the second lowest in two decades, but months with record high water occurrence appear to be increasing globally. River flows were slightly lower than the previous year. Record high river flows appear to be getting more common, and record low flows are less common. Lake volumes have been increasing over recent decades. High-storage records are broken more often. Many dry and wet records in terrestrial water storage - combining all parts of the terrestrial water cycle - were broken in 2023, despite several months of missing data.
Climate Change in the American Mind: Beliefs & Attitudes, Fall 2023, Leiserowitz et al., Yale Program on Climate Change Communication and the George Mason University Center for Climate Change Communication
Americans who think global warming is happening outnumber those who think it is not by a ratio of nearly 5 to 1 (72% versus 15%). 58% understand that global warming is mostly human-caused. By contrast, 29% think it is caused mostly by natural changes in the environment. 65% say they are at least “somewhat worried” about global warming, including 29% who are “very worried.” 28% hear about global warming in the media at least once a week.
Regional population dynamics and mobility trends in the Pacific, Bedford et al., University of Auckland
The authors discuss the contemporary demographic context and future dynamics of population change, including international mobility, in the Pacific region. A key finding is that it would be prudent to monitor population change in five different Pacific population clusters, rather than focussing on the usual three sub-regions of Melanesia, Micronesia, and Polynesia. These clusters are Western Pacific, Central Pacific, Eastern Pacific, Northern Pacific, and French Territories. Population change and climate change are similar in that both require lengthy timeframes for their monitoring and analysis. The authors' primary objective is to produce a synthesis of findings relating to population change in the Pacific region over the century between 1950 and 2050.
The year of 2023 was the second-warmest on record for the UK, narrowly behind the record set as recently as 2022, McCarthy et al., Met Office
The authors look back at the UK’s climate in 2023, the significant climate events that shaped the year and how human-caused climate change influenced them. they found that eight of the 12 months of the year were warmer than average. Somewhat unusually, the warmest periods were in June and September, with the high summer months of July and August generally cooler and wetter. June was the hottest month of the year for the first time since 1966 and was the hottest June on record by a large margin. Through a climate attribution analysis, they showed that a year as warm as 2023 has been made around 150 times more likely due to human-caused climate change. They would expect to reach or exceed the 2023 annual temperature in around 33% of years in the current climate. 2023 was relatively wet with 1,290mm of rainfall, making it the UK’s 11th wettest year in a series going back to 1836. The few wintery cold spells of the year were relatively short-lived. 2023-24 has seen the most active start to the storm season since naming storms began in 2015.
2023 Standard Scenarios Report: A U.S. Electricity Sector Outlook, Gagnon et al., National Renewable Energy Laboratory
The authors present the ninth edition of the annual Standard Scenarios. They summarize 53 forward-looking scenarios of the U.S. electricity sector that have been designed to capture a wide range of possible futures. The Standard Scenarios are simulated using the Regional Energy Deployment System (ReEDS) model, which projects utility-scale electricity sector evolution for the contiguous United States using a system-wide, least-cost approach subject to policy and operational constraints. A subset of the scenarios are simulated in the PLEXOS production cost model to obtain a broader suite of metrics at the hourly resolution, which are made available through the National Renewable Energy Laboratory’s (NREL’s) annual Cambium3 data sets.
Global Drought Snapshot 2023, Tsegai et al., United Nations Convention to Combat Desertification
The authors provide both current and future effects of drought. For present effects paint a vivid picture of the multiple impacts of drought. From dwindling reservoir levels to declining crop yields, from loss of biological diversity to famines, the numbers reveal the “loud” reality of drought. The majority of data points used were published within the last 24 months. To combat the negative effects of drought, global drought resilience is essential. the authors then shift the focus away from the multiple negative and often cascading impacts to building resilience, which involves proactive measures that minimize vulnerability and enhance adaptive capacity. This encompasses various sectors, including agriculture, water management, and disaster preparedness. In addition, raising awareness and providing support to vulnerable communities can help build their resilience in times of drought.
Drought and Extreme Heat Impacts to Data Centers in Northern California, Gemma Anderson, Infrastructure Security Division, Cybersecurity and Infrastructure Security Agency, Department of Homeland Security
Commonly, data centers are designed and operated on the assumption of stationarity of the climate. Historical weather data informs the basis of their design and operations. However, as a result of climate change, this assumption is not valid and poses a great risk for data centers. In the coming decades, Northern California’s drought and extreme heat risk is projected to increase significantly. The author provides a drought and extreme heat impact assessment of data centers in this region. The author identifies the climate variables and analytics relevant for assessing data center-specific impacts from extreme heat and drought and demonstrates how to access and understand future climate projections from climate models. The author emphasizes the importance of including future climate projections in data center design and planning.
The Global Risks Report 2024, World Economic Forum
The authors present the findings of the Global Risks Perception Survey which captures insights from nearly 1,500 global experts. The authors analyze global risks through three-time frames to support decision-makers in balancing current crises and longer-term priorities. Chapter 1 explores the most severe current risks, and those ranked highest by survey respondents, over two years, analyzing in depth the three risks that have rapidly accelerated into the top 10 rankings over the two-year horizon. Chapter 2 focuses on the top risks emerging over the next decade against a backdrop of geostrategic, climate, technological, and demographic shifts, diving deeper into four specific risk outlooks. The authors conclude by considering approaches for addressing complex and non-linear aspects of global risks during this period of global fragmentation.
Global Warming Acceleration: Causes and Consequences, Hansen et al., Columbia University
Record global temperature in 2023 helps reveal the acceleration of global warming on decadal time scales. The proximate cause of the acceleration is an increase in Earth’s energy imbalance, specifically a substantial darkening of the planet (decreased albedo) equivalent to a CO2 increase of more than 100 ppm, although it is difficult to apportion the albedo change between aerosol forcing and cloud feedbacks because of limited global measurements. Large 2023 warming is consistent with prior research; reduced aerosol cooling and high climate sensitivity. The authors expect record monthly temperatures to continue into mid-2024 due to the present large planetary energy imbalance, with the 12-month running-mean global temperature reaching +1.6-1.7°C relative to 1880-1920 and falling to only +1.4 ± 0.1°C during the following La Nina. Considering the large planetary energy imbalance, it will be clear that the world is passing through the 1.5°C ceiling, and is headed much higher unless steps are taken to affect Earth’s energy imbalance.
The New Climate Denial, The Center for Countering Digital Hate
The authors quantify the startling and important rise over the past five years in what they call “New Denial” — the departure from rejection of anthropogenic climate change, to attacks on climate science and scientists, and rhetoric seeking to undermine confidence in solutions to climate change. “New Denial” claims now constitute 70% of all climate denial claims made on YouTube, up from 35% six years ago. The study centers on data analysis performed by an AI tool, CARDS, developed by academics Travis G. Coan, Constantine Boussalis, John Cook, and Mirjam O. Nanko. The AI allowed the authors to quantify the frequency of different types of climate denialist claims in text. The authors identified the changing tactics of climate deniers on YouTube by analyzing thousands of hours of transcripts of videos on the platform from 96 channels dating back to 2018.
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.
