The report finds that human-induced climate change has reduced rainfall in Jamaica by approximately 6% and in Puerto Rico by about 9%. These changes have increased the likelihood of severe effective precipitation events in both regions compared to a pre-industrial climate. The study highlights that warmer temperatures intensify drought severity through higher evaporation, making the 2026 early wet season rainfall deficits more frequent and severe.

The document presents seven facts regarding the National Park Service (NPS) and its connection to Hispanic/Latino populations. It notes a significant underrepresentation of Latinos in the NPS workforce and leadership compared to their share of the U.S. population. It highlights historical figures like George Meléndez Wright and sites such as Chicano Park and Chaco Culture National Historical Park. The text also expresses concern over the removal of permanent workers since January 2025, the exclusion of U.S. territories from public surveys, and proposed mineral withdrawals in the Greater Chaco region.

ClientEarth warns FMCG companies that relying on recycling is insufficient to mitigate legal risks and urges a shift toward upstream plastic reduction. The document details risks from mandatory due diligence laws, product liability for health harms, and anti-greenwashing enforcement, specifically targeting misleading 'recyclable' claims. It also highlights the impact of the EU's Corporate Sustainability Reporting Directive (CSRD) on plastic-related disclosures.

The Union of Concerned Scientists analyzed nearly eight million affordable homes and found that 79.1% were located in counties experiencing at least one week's worth of heat alerts in 2024. The report highlights that people of color, older adults, and individuals with disabilities are disproportionately affected due to substandard housing, the urban heat island effect, and energy insecurity. Key recommendations include increasing funding for the Low-Income Home Energy Assistance Program (LIHEAP), implementing cooling inspection standards for subsidized homes, and updating building codes to improve heat resilience.

The Union of Concerned Scientists analyzed the intersection of the housing crisis and extreme heat, finding that residents of affordable housing—particularly people of color, older adults, and people with disabilities—face significant risks. Analysis of 2024 heat alerts shows that the highest shares of exposed affordable housing are in the Northeast and Southeast, while Texas, California, and New York have the highest total number of exposed homes. The report advocates for increased investment in climate-resilient affordable housing and the expansion of the Low-Income Home Energy Assistance Program to improve cooling and building efficiency.

The report identifies critical failure modes in ground-mount solar PV systems exposed to extreme winds, such as the failure of top-down clamps and low-cycle fatigue in module frames. It recommends high-load modules (4,000 Pa uplift), through-bolting with specialized washers, and dual-post foundation designs to improve survivability in hurricane-prone regions.

Between 2020 and 2024, climate change increased the number of 'pregnancy heat-risk days'—days exceeding the 95th percentile of local temperatures—in every analyzed country. In 90% of countries and 63% of cities, these risk days at least doubled compared to a world without climate change. The most significant increases occurred in developing regions, particularly the Caribbean, where 15 countries saw an average of at least 60 additional risk days annually, representing roughly one-fifth of a typical pregnancy. Beyond heat, the report notes that climate-driven air pollution, flooding, and infrastructure damage further threaten maternal health and birth outcomes.

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 document argues that virtual power plants (VPPs), which aggregate decentralized energy resources (DERs) like rooftop solar and battery storage, can reduce the Caribbean's dependence on expensive imported fossil fuels and improve grid stability against climate-driven threats like hurricanes. Using the US Virgin Islands as a case study, the report evaluates the scalability of VPPs to provide energy, capacity, and ancillary services, offering recommendations for policymakers and utilities to transition toward cleaner, more resilient energy systems.

The document outlines recommendations for the EPA to integrate climate justice into environmental protections. It emphasizes the need for transparent, holistic decision-making, the acknowledgment of historic biased policies, and the strengthening of the National Environmental Protection Act (NEPA) to better account for cumulative stressors and the specific needs of marginalized communities and non-mainland US territories.

As of October 2024, there are 12,241 committed electric school buses in the U.S., with nearly 5,000 already delivered or operating. Adoption is heavily driven by the EPA's Clean School Bus Program, which funds 67% of all commitments and prioritizes high-poverty, rural, and tribal districts. While California leads in absolute numbers, the Northeast and Midwest have seen significant percentage increases. Seven states have enacted statutory zero-emission transition requirements, and WRI projects that 62% of all school bus sales will be electric by 2032 following revised EPA greenhouse gas emission standards.

The document details how rising sea surface temperatures, driven by human-caused climate change, are increasing the frequency and intensity of rapid intensification in tropical cyclones. It highlights that 70% of billion-dollar tropical cyclones in the U.S. since 1980 underwent rapid intensification, contributing to over $1.4 trillion in damages and nearly 7,000 deaths.

As of June 2024, the U.S. has 12,164 committed electric school buses, with 67% funded by the EPA's Clean School Bus Program. Adoption is widespread across 49 states, with California leading in total numbers, while the Southeast has seen significant recent growth. The report finds that deployment is increasingly equitable, with a majority of buses now located in high-poverty districts and areas with high air pollution, though adult asthma rates show a more even distribution.

The document details the technical approach for mapping disruptive flooding and its impact on critical infrastructure across US territories. It describes the use of NOAA tide gauge data, digital elevation models, and three sea level rise scenarios (low, medium, and high) to project inundation. The analysis overlays these flood maps with datasets covering housing, education, industrial sites, energy, government, and health facilities, while incorporating socioeconomic data from the White House Council on Environmental Quality to assess impacts on disadvantaged communities.

The Union of Concerned Scientists analysis finds that climate-driven sea level rise will expose over 1,600 critical infrastructure assets in the US to disruptive flooding at least twice per year by 2050. Public and affordable housing are the most vulnerable assets, with a disproportionate burden falling on disadvantaged communities. By 2100, the scale of risk depends heavily on global emissions, with the high scenario potentially affecting 15,081 assets. The report recommends science-informed planning, scaled-up funding, and a focus on reducing historical inequities to build coastal resilience.

As of June 2023, there are 5,982 committed electric school buses across 914 U.S. school districts or private fleet operators. Adoption is heavily driven by the EPA's Clean School Bus Rebate Program, which funded 39% of all committed buses. While California leads in total numbers, adoption is becoming more geographically distributed, with 49 states now having commitments. The report finds that adoption is occurring equitably, with a majority of buses located in low-income districts and areas with high air pollution. Type C buses are the most common, making up 62.5% of commitments.

The Mississippi Clean Hydrogen Hub (MCHH) aims to leverage natural salt domes for large-scale, long-duration green hydrogen storage to safeguard energy security. Domestically, the hub is positioned to supply critical sectors in the Gulf Coast, Midwest, and Mid-Atlantic, potentially serving 52% of US refining, 44% of shipping, 19% of steelmaking, and 17% of heavy-duty trucking capacity. It also seeks to bolster US fertilizer security by transporting green hydrogen feedstock via the Mississippi River to the Midwest. Internationally, the MCHH intends to establish green shipping corridors to help the EU diversify away from Russian fossil fuels and provide backup energy to climate-vulnerable nations in Latin America and the Caribbean. The report argues that an initial public investment of $500 million could unlock billions in private capital by 2026, creating a national strategic hydrogen reserve and reducing industrial losses from power outages.

As of December 2022, there are 5,612 committed electric school buses in the US, a significant increase driven largely by the EPA's Clean School Bus Rebate Program. While California leads in total numbers, adoption has expanded to all 50 states and is increasingly concentrated in low-income and minority communities, though the report emphasizes the need for continued focus on equity and infrastructure support.

The 2022 Climate, Environmental, and Energy Congressional Hearings Tracker catalogs hearings held by various U.S. House and Senate committees. The tracker covers a wide array of topics including the Inflation Reduction Act, the Bipartisan Infrastructure Law, electric vehicle infrastructure, methane pollution, and agricultural resiliency. It details the specific dates and titles of hearings across committees such as the House Select Committee on the Climate Crisis and the Senate Committee on Energy and Natural Resources.

The U.S. has seen a steady increase in the frequency and cost of billion-dollar weather and climate disasters since 1980. In 2022, by September 30, the country had already experienced 15 such events totaling $29.3 billion in losses, exceeding the historical annual average of seven. The time between these disasters has shrunk from 82 days in the 1980s to an average of 18 days between 2017 and 2021, reducing the time available for recovery and preparation. While hurricanes are the most costly event type, the overall trend of increasing extremes is linked to human-caused greenhouse gas emissions, with projections suggesting further intensity without rapid emissions cuts.
