Open access notables Fossil fuel emissions dominate Northern Hemisphere CO2 seasonal cycle trends under mitigation scenarios , Jin et al., Nature Communications Variations in the atmospheric CO2 seasonal cycle across the Northern Hemisphere have historically been dominated by terrestrial ecosystems, making ground-based observations a reliable proxy for terrestrial carbon dynamics. However, whether this dominance will persist in the future remains uncertain. Here we combine atmospheric transport modeling with factorial simulations to assess and attribute future changes in the CO2 seasonal cycle through 2100. We show that the dominant drivers of these changes shift fundamentally across scenarios. Under the high-emission scenario (SSP5-8.5), strengthening land sinks dominate and amplify CO2 seasonal variability, preserving ground-based observations as a reliable terrestrial proxy. In contrast, under the low-emission scenario (SSP1-2.6), CO2 seasonal amplitude declines widely, driven primarily by reduced fossil fuel emissions and their dampened seasonality. Consequently, established ground-based CO2 observations may no longer reliably track terrestrial carbon dynamics under mitigation pathways, underscoring the need for new approaches for monitoring and climate policy verification. Dynamic evaporative and radiative cooling for efficient year-round energy savings , Zhou et al., Science Advances Electricity-free radiative cooling (RC) techniques are gaining ever-increasing attention to decrease energy consumption and carbon dioxide (CO2) emissions. However, the cooling power of RC in summer is severely limited by atmospheric window constraints and its negative effect in winter offsets annual energy savings in four-season regions. This study introduces a dynamic evaporative and radiative cooling (DERC) device to maximize the cooling power in hot summer and achieve year-round dynamic thermal management. Adaptive to changes in environmental temperature, the DERC device demonstrates dynamic regulation of water evaporation, along with notable modulation of solar and thermal radiation (ΔAsol = 87%; ΔεBroadband = 63%). Theoretical and real-time experiments demonstrate that the DERC device is more energy-efficient than cutting-edge dynamic radiative cooling (DRC) techniques. The energy-saving simulations indicate that the DERC device yields over 40% primary energy savings and CO2 emission reduction compared to the DRC device. This DERC device represents a conceptual advancement, paving the way for global energy savings and emission reductions. Heating up the headlines: How tabloid framing reshaped Germany's Buildings Energy Ac t , Loschke et al., Energy Research & Social Science Media has become a decisive force in shaping climate and energy policy, influencing not only which issues gain attention but also how they are framed and contested. This paper examines how BILD, Germany's largest tabloid, transformed the 2023 reform of the Buildings Energy Act (GEG) into one of the most polarizing political controversies in recent German history. Analyzing a corpus of 333 BILD articles from January 2023 to March 2024, we identify three dominant rhetorical strategies – personalisation, economic alarmism, and ideological framing – epitomised by the term “Heizungshammer”, which appeared over 250 times in BILD alone and spread to more than 1100 articles across the broader press. These narratives produced concrete policy outcomes: the progressive dilution and eventual abandonment of the 65% renewable energy obligation, the cancellation of planned building efficiency standards, and a reversal of Germany's position in EU negotiations on the Energy Performance of Buildings Directive. The case demonstrates that tabloid framing can migrate directly into legislative outcomes, with measurable consequences for climate governance ambition, highlighting the fragility of climate legislation in an age of digital populism. Shades of Swedish climate scepticism: an exploration of explanatory factors on doubts about climate change , Mendy & Lindvall, Environmental Sociology This study examines the drivers of climate scepticism in Sweden, distinguishing between epistemic scepticism – doubts about the scientific evidence of climate change – and response scepticism , concerning doubts about the need or effectiveness of climate mitigation. Using a large-scale survey (n = 5280), we analyse how variants of political ideology – regarding economic and material aspects, and cultural values captured on the GAL-TAN scale – and trust shape these forms of scepticism. While relatively few respondents expressed epistemic scepticism, response scepticism was more prevalent. Low trust in scientists is the strongest determinant of epistemic scepticism, alongside TAN-oriented ideology. TAN orientation associates more strongly with response scepticism than epistemic scepticism, suggesting that individuals who accept climate science may still oppose mitigation policies, possibly due to a proclivity of social dominance orientation or political cues. A novel result is that attributional uncertainty, beliefs that climate is changing equally due to human and natural causes, is found to strongly associate with response scepticism, suggesting that more effective climate communication could alleviate such scepticism. The paper underscores the need to disentangle social mechanisms behind different sceptical climate beliefs and to refine the concept of response scepticism, as it may reflect distinct psychological and political dynamics . From this week's government/NGO section : The Power Behind AI. Wave of Dirty Gas Power Plants Planned for Data Centers , Bird et al., The Environmental Integrity Project: At least 74 natural gas-fired power plants are planned across the U.S. to provide energy for the rapidly growing data center industry. These proposed gas plants, which would be dedicated to serving data centers, are expected to generate 143 gigawatts of electricity – enough to power the state of California nearly three times over. The plants would also release nearly 662 million tons per year of greenhouse gas pollution, which would have the climate-warming effect of 140 million cars and trucks driving for a year or the emissions from the entire nation of Australia. Beyond greenhouse gases, this wave of power plants for data centers could also release 159,142 tons of health-harming air pollutants, including 44,281 tons of nitrogen oxides that contribute to smog and lung damage and 32,684 tons of fine particulate matter, which can trigger heart and asthma attacks. And this is just the tip of the iceberg. This pollution is a small fraction of the likely environmental effect of the booming artificial intelligence (AI) industry and affiliated data centers. These 74 planned gas plants, including 71 new power plants and three plant expansions, would be connected directly to data centers — so-called “behind-the-meter” power plants. These plants are designed to provide their electricity primarily to data centers and not to compete with local households and businesses on regional power grids. More power plants are being planned across the U.S. that will indirectly serve the growing data center industry along with other consumers on the grid, which will likely drive up electricity prices for nearby residents. Code, carbon, kilowatts: AI’s hidden toll and the race to green the grid , Patrick Hoffmann and Katharina Utermöhl, Allianz Research Data-center investment reached USD580bn in 2025, putting AI on track to become one of the world's fastest-growing sources of electricity demand. Installed capacity is expected to double by 2030, with AI workloads already accounting for 15–20% of data-center electricity use and potentially approaching 40% by the end of the decade. Yet the sector's environmental footprint remains underestimated as most analyses focus only on operational electricity use. The authors take a broader systems view across 26 countries (+93% of global capacity), adding lifecycle emissions, water use and AI's growing resource demand. Identical workloads can generate up to 24 ti mes more emissions depending on the emission intensity of the grid, making location as decisive as demand growth. Fossil-dependent grids in Indonesia, India and Malaysia exceed 600 gCO 2 /kWh, compared with under 30 gCO 2 /kWh in Norway and Sweden. The US and China, which host the largest data-center clusters, sit in between at 384 gCO 2 /kWh and 526 gCO 2 /kWh, respectively, giving Europe's cleaner power mix a structural advantage for low-carbon AI growth. These disparities are amplified by transmission and distribution losses of 10–15% in some markets, while less reliable grids raise electricity needs and dependence on backup generation. 125 articles

Articles/Reports from Agencies and Non-Governmental Organizations Addressing Aspects of Climate Change Uneconomic Coal Operations in PJM: Market Distortions, Cost Impacts, and Policy Considerations , Roumpani et al., The Citizens Utility Board of Ohio Uneconomic coal operations are not isolated incidents, but occur by a combination of permissive market rules, utility incentives, regulatory decisions, and policy interventions. In combination, these weaken price signals and allow aging, high-cost coal units to remain online even when they are no longer competitive. The authors examine mechanisms that allow or drive uneconomic coal operations including self-scheduling, in which generators operate regardless of market prices, often recovering losses through state-approved power cost recovery mechanisms.; uplift payments, which compensate generators under specified conditions for operating or committing when market revenues are insufficient; Reliability Must-Run (RMR) agreements, which keep uneconomic units online after retirement announcements due to localized reliability concerns; and policy interventions, including recent federal actions, that override or blunt market signals. The Power Behind AI , Bird et al., The Environmental Integrity Project At least 74 natural gas-fired power plants, which could release as much climate-warming pollution as the nation of Australia each year, are planned across the U.S. to provide energy for the rapidly-growing data center industry. These proposed gas plants, which would be dedicated to serving data centers, are expected to generate 143 gigawatts of electricity – enough to power the state of California nearly three times over – along with 662 million tons per year of greenhouse gas pollution. Greenpeace Report on Wildfires in Portugal , Viegas et al., Greenpeace The wildfire risk in Portugal has been changing over the past decades due to the positive or negative effects of various factors, some related to natural or physical conditions and others to socioeconomic, political, and organizational activities. Using statistical data on national fire occurrence and extent, which have been available since 1943, and on climatic factors, vegetation cover and properties, population evolution, and administrative changes in the wildfire risk management system, the authors provide an overview of wildfires in Portugal and their evolution over the past decades. The long-term data are used to provide an overall perspective on some of the major factors present over these eight decades. Carbon Markets, Unseen Workers: Labor Rights and Governance Gaps in Africa , Otieno et al., Solidarity Center The authors address a critical gap by analyzing carbon markets through a labor and political economy lens. Grounded in experiences from Kenya, Ghana, South Africa, and Nigeria, the authors examine how both compliance and voluntary carbon market mechanisms shape employment, labor conditions, and worker participation. The authors illuminate the role of workers across carbon value chains, assess alignment with the International Labor Organization's core conventions and decent work principles, identify governance and accountability gaps, and explore pathways for worker and trade union engagement. The authors provide a framework for workers and their organizations to develop their own engagement and advocacy strategies tailored to their specific priorities. Hawai'i’s Electricity Future: Three Findings on Solar Reform, Enhanced Geothermal, and the JERA LNG Proposal , Ethan Hartley and Michael Roberts, University of Hawaii Economic Research Organization The authors ask what Hawaiian Electric and Hawai‘i should build to keep O‘ahu’s lights on through 2050 while transitioning to 100 percent clean power, and what it will cost. The analysis uses a planning model — the kind of computer model utility companies and grid regulators run when they have to decide which power plants to build over the next two decades — and solves it more than three hundred times under different assumptions about oil prices, solar and battery costs, land-use rules, the Public Utility Commission-approved Waiau Repower, and the JERA liquefied natural gas proposal. Three findings hold across all the variations tested; cheaper solar and battery deployment is by far the biggest economic lever Hawai‘i has; under defensible current cost assumptions, O‘ahu does not need to build any new fuel-burning power plant beyond what is already committed; and Enhanced Geothermal Systems (EGS) are the largest non-solar economic lever — if the technology delivers on the optimistic cost trajectory. California Salmon Strategy for a Hotter, Drier Future: Restoring Aquatic Ecosystems in the Age of Climate Change, Second Progress Report , State of California In January 2024, California adopted the California Salmon Strategy for a Hotter, Drier Future (Salmon Strategy), identifying six priorities and 71 actions to restore struggling salmon populations. Since the release of the Salmon Strategy, the state has fully completed 49% of the actions and partially met or advanced progress on 51% of the actions. This progress report describes progress for the 71 actions across two stages, those that are in-progress and those that have been completed. For example, salmon fishing is back, salmon are returning to the Klamath Basin, salmon have been reintroduced to cold-water habitat on the Yuba River, and river flows for salmon have been protected in the Scott and Shasta rivers. The Impact of New York's 2026 Climate Law Retreat , Jonathan Binder and Vincent Nolette, Sabin Center for Climate Change Law, Columbia University On May 26, 2026, New York State enacted significant revisions to its 2019 Climate Leadership and Community Protection Act (CLCPA). The 2026 Amendments, which include changes to the greenhouse gas (GHG) emission accounting methods, the statewide GHG emission limits, and the requirement to adopt implementing regulations, collectively weaken the Act's ambition. New York’s retreat from state climate action after championing it for years reflects a broader national trend of de-prioritizing mitigation efforts. The 2026 Amendments will have vast and important consequences for the implementation of the CLCPA. Numerous actions will need to be updated through rulemaking, guidance, or other administrative processes. This will require a significant and resource-intensive undertaking by the State, and especially by the Department of Environmental Conservation (DEC). Amending the statute was largely done behind closed doors as part of the state budget process. By contrast, most of these administrative actions to implement the amended CLCPA will require a public-facing process. In the background, the risk and actual commencement of litigation will continue to shape the Act’s outcomes. Despite these amendments, DEC, with support of various stakeholders, retains significant discretion to maximize the CLCPA's benefits through strong implementation. Stafford Act's Requirement to Consider Climate Change in State Hazard Mitigation Plans , Olivia Guarna, Sabin Center for Climate Change Law, Columbia University Congress passed the Stafford Act in 1988 to provide a means for sustained and coordinated federal aid in response to disasters. The Stafford Act includes a comprehensive non-emergency hazard mitigation program. Hazard mitigation assistance empowers states, tribes, and local governments to engage in planning and mitigation activities that improve disaster outcomes and minimize losses in their jurisdictions. A key component of the Stafford Act’s hazard mitigation assistance programs, which are implemented by the Federal Emergency Management Agency (FEMA), is the development of state hazard mitigation plans. The Stafford Act requires state hazard mitigation plans to “identify the natural hazards, risks, and vulnerabilities of areas in the State.” The author argues that, under the Stafford Act, state plans must consider the effects of climate change on natural hazard risks and vulnerabilities. Code, carbon, kilowatts: AI’s hidden toll and the race to green the grid , Patrick Hoffmann and Katharina Utermöhl, Allianz Research Data-center investment reached USD580bn in 2025, putting AI on track to become one of the world's fastest-growing sources of electricity demand. Installed capacity is expected to double by 2030, with AI workloads already accounting for 15–20% of data-center electricity use and potentially approaching 40% by the end of the decade. Yet the sector's environmental footprint remains underestimated as most analyses focus only on operational electricity use. The authors take a broader systems view across 26 countries (+93% of global capacity), adding lifecycle emissions, water use and AI's growing resource demand. Identical workloads can generate up to 24 times more emissions depending on the emission intensity of the grid, making location as decisive as demand growth. Fossil-dependent grids in Indonesia, India and Malaysia exceed 600 gCO2/kWh, compared with under 30 gCO2/kWh in Norway and Sweden. The US and China, which host the largest data-center clusters, sit in between at 384 gCO2/kWh and 526 gCO2/kWh, respectively, giving Europe's cleaner power mix a structural advantage for low-carbon AI growth. These disparities are amplified by transmission and distribution losses of 10–15% in some markets, while less reliable grids raise electricity needs and dependence on backup generation. A Study of Architectural Measures to Reduce Overheating. Literature Review and Analysis , Historic England The authors identified different historic architectural measures used in England and in British colonial architecture abroad. They investigated how passive architectural measures, such as awnings or shutters, have been used in the past to reduce solar gain and seasonal overheating. The different measures are supporting Historic England in identifying appropriate adaptation options to a changing climate. As temperatures increase, there is a growing risk of overheating occurring in buildings. This could lead to thermal discomfort, health implications for building occupants due to thermal stress, and increased energy usage due to a rising demand for cooling to counter the overheating. In addition to identifying what measures were used historically, the authors also sought to identify the different risks, regulations and limitations that might need to be considered when contemplating their integration into an existing historic building. Glass Half Full: Building a Decarbonized U.S. Power Sector , Lily Bermel, Center for Energy and Environmental Policy Research, Massachusetts Institute of Technology The Inflation Reduction Act of 2022 (IRA) was built, sold, and attacked as the largest climate investment in U.S. history. It enacted an extensive suite of clean energy tax credits and included hundreds of billions of dollars in grant and loan programs, reestablishing the United States as a climate leader. The One Big Beautiful Bill Act of 2025 (OBBBA) rescinded the vast majority of the IRA’s grant and loan programs and restructured the clean energy tax credit framework by phasing out the wind and solar tax credits and adding restrictions to the others. Many clean energy advocates saw these changes as the death of the IRA and warned of dire consequences for the American energy transition. Indeed, removing and restricting energy tax credits will contribute to higher energy prices, project cancellations, job losses, and less energy added to the grid at a time when power demand is surging. Policymakers designing the next wave of decarbonization policy need to start with a clear-eyed understanding of how the current environment shapes the energy transition. The author provides one for the power sector, the backbone of that transition. The author assesses how much the current policy environment preserves the benefits of the prior policy environment, situates those modeled results within the real-world forces shaping delivery, and draws out what the findings imply for future policy priorities and public spending. The Power Behind AI. Wave of Dirty Gas Power Plants Planned for Data Centers , Bird et al., The Environmental Integrity Project: At least 74 natural gas-fired power plants are planned across the U.S. to provide energy for the rapidly growing data center industry. These proposed gas plants, which would be dedicated to serving data centers, are expected to generate 143 gigawatts of electricity – enough to power the state of California nearly three times over. The plants would also release nearly 662 million tons per year of greenhouse gas pollution, which would have the climate-warming effect of 140 million cars and trucks driving for a year or the emissions from the entire nation of Australia. Beyond greenhouse gases, this wave of power plants for data centers could also release 159,142 tons of health-harming air pollutants, including 44,281 tons of nitrogen oxides that contribute to smog and lung damage and 32,684 tons of fine particulate matter, which can trigger heart and asthma attacks. And this is just the tip of the iceberg. This pollution is a small fraction of the likely environmental effect of the booming artificial intelligence (AI) industry and affiliated data centers. These 74 planned gas plants, including 71 new power plants and three plant expansions, would be connected directly to data centers — so-called “behind-the-meter” power plants. These plants are designed to provide their electricity primarily to data centers and not to compete with local households and businesses on regional power grids. More power plants are being planned across the U.S. that will indirectly serve the growing data center industry along with other consumers on the grid, which will likely drive up electricity prices for nearby residents. City of Boulder, Climate Action Plan , City of Boulder This Climate Action Plan outlines how Boulder's aim to reduce emissions, strengthen infrastructure resilience and invest in communities most affected by climate change. It connects long-term goals with practical strategies already in motion across the city. Already occurring are extreme heat, longer droughts, greater fire risk and rising energy burdens, especially for community members with the fewest resources. These effects are not future threats. They are here now. The city is responding with clear targets, coordinated action and a focus on long-term public benefit. Mental Images of Global Warming in the Indian Mind , Thaker et al., Yale Program on Climate Change Communication Most Indians are unfamiliar with the term "global warming": When asked to name the first word or phrase that came to mind, 58% were unable to give a specific response or said they do not know. Those familiar with “global warming” associate it primarily with heat, water, and pollution. Familiarity with the term “global warming” varies sharply, with higher recognition among more educated, higher income, and urban respondents. Investing in the green economy 2026: Resilience and reacceleration , Dai et al., London Stock Exchange Group The green economy has surpassed US$10 trillion despite energy shocks, policy divergence and market volatility. Against a backdrop of volatile markets, energy supply disruption and rising electricity demand, the authors analyze green investment opportunities and how the green transition is evolving by examining the size, growth, performance and financing of the global green economy across asset classes. The authors also examined how green assets are scaled via merger and acquisition with profitability analysis, the role of green bonds in supporting capital flows, and the diverging regional green economy shaped by decarbonization and energy security priorities. 50 State of Energy Affordability , Apadula et al., North Carolina Clean Energy Technology Center The authors provide updates on state and utility actions to address rising electricity costs, including utility business model reforms, utility oversight and cost recovery, infrastructure planning and procurement processes, customer cost allocation, and customer programs. Economic, Consumer Cost, and Pollution Impacts of Federal Energy Policy Changes , Robbie Orvis and Daniel O’Brien, Energy Innovation Policy and Technology The United States’ energy policy framework has shifted dramatically during the second Trump administration and 119th Congress. Over the past one and a half years, the federal government has overhauled many legislative and regulatory policies, creating significant implications for clean energy deployment. Energy prices continue rising, exacerbating the affordability crisis Americans are facing. The authors used the Energy Policy Simulator to model federal policy decisions made since January 2025 to determine what the near future holds for families and businesses in terms of energy costs, public health, job losses, and grid reliability. The authors analyze the effects of policy changes on energy prices, the economy, air pollution, and healthcare spending from 2026 to 2040. The author's modeling shows higher energy costs, worsening public health effects, and less capacity added to the grid – blocking new generation when it is needed most and increasing utility costs. Renewable Power Generation Costs in 2025 , Dardour et al., International Renewable Energy Agency Renewables remain the most cost-competitive source of new electricity generation. More than 90% of utility-scale renewable projects commissioned in 2025 delivered power below the cost of the cheapest new fossil-fuel plant built in their market. After more than a decade of steep declines, renewable power costs are stabilizing. In 2025, Solar PV remained at its 2024 level of USD $44/MWh, while wind continued to improve, with onshore wind falling to USD $33/MWh and offshore wind to USD $78/MWh. In contrast, most dispatchable renewable technologies recorded higher costs, with hydropower, geothermal and concentrating solar power rising to USD $62/MWh, USD $89/MWh and USD $115/MWh, respectively. Bioenergy was the exception, declining to USD $86/MWh. In 2025, renewables helped avoid an estimated USD 480 billion in fossil-fuel costs and about 8.4 gigatonnes of CO2 emissions, confirming their role not only as the cheapest new power, but as a pillar of energy security, economic stability and resilience.
