A letter from Members of Congress to the BOEM arguing that BP's Kaskida project in the Gulf of Mexico poses unacceptable risks to ecosystems and public health, citing failures in high-pressure, high-temperature (HPHT) technology qualifications and underestimated spill risks.

Wildfire smoke pollution in the U.S. has increased significantly, with per-person exposure four times higher between 2020-2024 than during 2006-2019. Research indicates that fine particulate matter (PM2.5) from wildfire smoke caused approximately 164,000 premature deaths in the U.S. from 2006 to 2020, with human-caused climate change accounting for about 15,000 of those deaths. While the West and Northwest experience the most smoke days, smoke is a nationwide issue, with every county in the contiguous U.S. seeing at least 16 smoke days annually. The rise in smoke since 2016 has stalled or reversed air quality improvements in 30 U.S. states, threatening the goals of the Clean Air Act.

The report details how the Trump EPA used a rare Clean Air Act provision to grant pollution exemptions to 52 facilities owned by 25 companies, including BASF, Shell, and Westlake. It highlights that these exemptions undermine the HON Rule, which aimed to reduce carcinogenic emissions by nearly 80%. The document further links these regulatory rollbacks to significant lobbying expenditures by the chemical industry and the American Chemistry Council, noting that several companies are expanding the very facilities that received exemptions.

Analysis of 247 major U.S. cities shows that under high-emissions scenarios, summer high temperatures are projected to increase by an average of 3.6°F by 2060 and 7.9°F by 2100. For many cities, these future conditions will resemble current climates in locations hundreds of miles to the south, with 16 cities projected to reach temperatures only currently found in Pakistan, the Middle East, and North Africa.

GreenLatinos condemns the use of military and law enforcement force during immigration raids in Los Angeles, asserting that such tactics are used to distract from the federal government's efforts to undermine California's air quality, public health, and public lands. The statement provides a comprehensive list of legal and emergency resources for impacted communities in Southern California, including rapid response hotlines and 'know-your-rights' guidance.

An attribution analysis reveals that 88% of 247 major U.S. cities have seen an increase in extremely hot summer days strongly influenced by climate change since 1970. On average, these cities now experience six such days annually, compared to zero in the 1970s, with the most significant increases occurring in the South, particularly in Texas and Louisiana.

The document outlines the cyclical relationship between climate change and wildfires, highlighting how rising temperatures and droughts increase fire frequency while the resulting emissions accelerate global warming. It focuses on the US-Mexico border region—specifically Southern California, Arizona, and Northern Baja California—where smoke stagnation and limited healthcare access disproportionately affect migrants, outdoor workers, and marginalized urban populations in cities like Tijuana, Nogales, and El Paso. The guide suggests journalistic angles for investigating cross-border firefighting coordination between agencies like CAL FIRE and CONAFOR, the health impacts of smoke on vulnerable groups, and the effectiveness of local air quality monitoring tools.

The document outlines the global feedback loop between climate change and wildfires, while highlighting the specific vulnerabilities of border communities and migrants in the US-Mexico region. It provides a framework for reporting on transboundary air pollution, the health risks of smoke exposure for marginalized groups, and the role of cross-border fire management coordination.

Over 10 million US homes still rely on delivered fuels like oil and propane, which are expensive and polluting. Transitioning these households to air-source heat pumps (ASHPs) and heat pump water heaters (HPWHs) could save US customers nearly $8 billion annually in energy bills and significantly reduce carbon and air pollution. The document advocates for state-level policy changes, such as allowing fuel switching in utility energy efficiency programs and implementing clean heat standards, alongside targeted outreach and contractor training to support rural and low-income households.

The Inter-American Institute for Global Change Research (IAI) is expanding its Expert List to provide regional actors with a curated directory of professionals for technical consultations. Nominees must possess authoritative knowledge in one of eight priority themes: Food Security, Energy Security, Water Security, Biodiversity and Ecosystem Services, Climate Action, Health and Well-Being, Poverty and Equity, or Clean Air, Water, and Soils. The list currently comprises investigators from IAI-funded projects and members of the Scientific Advisory Committee (SAC) and Science-Policy Advisory Committee (SPAC). Parties must submit nominations by 6 June 2025.

The report finds that while a majority of Armenians recognize the impacts of climate change—particularly on health—and support renewable energy, actual personal engagement in environmental activities remains low at 22%. Public trust in environmental action is highest for educational institutions and lowest for the private sector and NGOs. Significant barriers to participation include a lack of time, financial costs, and indifference.

The report finds that while a majority of Moldovans (61%) perceive their understanding of climate change as good or very good, actual engagement in environmental activities is around 57%. Public priorities for environmental protection are led by access to clean water and sanitation and waste management. There is significant concern (65%) regarding dependence on foreign energy sources, with strong support for developing solar and wind power. Educational institutions are viewed as the most important actors in driving environmental action, while corporate sustainability initiatives receive the highest level of public support. Barriers to individual engagement include a lack of time (62%) and financial costs (34%).

The report finds that while a majority of Ukrainians acknowledge the personal impacts of climate change and support renewable energy development, significant barriers such as financial costs and a perceived lack of common practice hinder individual engagement. Public trust in environmental action is highest for volunteers and youth activists, while the central government is viewed as moderately important but less efficient. Energy security is a major concern, with a strong preference for solar and wind power to reduce foreign dependence.

The Danger Season 2025 microsite integrates National Weather Service (NWS) alerts, population data, social disadvantage metrics from the Climate & Economic Justice Screening Tool (CEJST), Climate Central’s Climate Shift Index (CSI), and EPA/AirNow’s Air Quality Index (AQI). The methodology focuses on the period from May to October, identifying counties under extreme weather alerts or experiencing unhealthy air quality. It calculates four daily indicators: the total population facing alerts, the percentage of disadvantaged people affected, the percentage of the population facing at least one alert, and the proportion of extreme heat alerts attributable to climate change. The scope includes the contiguous United States, Alaska, Hawai'i, Puerto Rico, and the U.S. Virgin Islands, though certain datasets like CSI and AQI have specific geographic gaps.

The project transformed Terminal Binjai from an inefficient, inaccessible transit hub into a safe, inclusive node for green mobility through a participatory process. Key interventions included a design competition involving university students and residents, 'transect walks' to identify pain points, and the implementation of low-cost 'tactical urbanism' upgrades. These changes resulted in improved lighting, accessible pathways, and weather-protected shelters, complemented by the addition of 30 new buses to the bus rapid transit (BRT) system. The project's methodology has been codified into a Digital Mapping Toolkit to support equitable urban transport planning in other cities globally.

The Supreme Court of Appeal (SCA) ruled on 11 April 2025 that poor air quality in the Highveld Priority Area breaches constitutional rights and that the Minister of Environmental Affairs has a legal duty to prescribe regulations under section 20 of the National Environmental Management: Air Quality Act 39 of 2004 (NEM:AQA). The court found that while the law uses the permissive word 'may', this constitutes a mandatory duty once the 'jurisdictional fact of necessity' is established. The SCA declared that the Minister unreasonably delayed these regulations and directed their prescription within 12 months. Notably, the court affirmed that environmental rights under section 24 of the Constitution are immediately realisable rather than subject to progressive realisation based on available resources.

The report finds that while 61% of Moldovans describe their knowledge of climate change as 'good' or 'very good', there is a significant gap between this perception and actual engagement. Public priorities for environmental protection focus on water access and waste management, while energy security is a major concern, with 65% of respondents worried about dependence on external energy sources. Support for the green transition is highest for corporate sustainability and renewable energy, though high costs remain a primary barrier to the adoption of renewable energy in households.

Main Street 1549 (Pty) Ltd proposes 'downscaled and non-invasive' surveys in Licence Blocks 9 and 11B/12B in the Outeniqua Basin to inform future oil and gas production infrastructure. The surveys involve seafloor mapping, sampling, and the use of Remote Operated Vehicles (ROVs), with a 500-metre exclusion zone around vessels. Potential impacts include disruption to marine life (specifically whales, dolphins, and migratory fish), noise and water pollution from vessel discharges, and negative effects on local livelihoods tied to fishing and tourism. The document also highlights risks to the cultural and spiritual heritage of indigenous groups who view the area as 'living' waters. Public comments on the Draft Scoping Report are requested by 3 April 2025.

The research identifies that while health and environmental benefits motivate the transition to electric school buses, districts are hindered by concerns over cost, infrastructure, and technology. Notably, geography and locale influence district needs more than priority status, and most districts do not currently integrate equity considerations into their electrification processes.

The document examines the potential for Nigeria to reduce methane emissions in its oil and gas sector, noting that such actions could unlock USD 1.5 billion annually and support the country's commitment to reduce emissions by 30% by 2030 under the Global Methane Pledge.
