The document explains how climate change—specifically warmer winters, hotter summers, and altered precipitation—is expanding the range and survival of disease-carrying insects like mosquitoes and ticks. It highlights specific threats in the US, such as Eastern Equine Encephalitis in New England and Lyme disease in the Northwest, while noting that over 8 billion people could be at risk of malaria and dengue by the end of the 21st century if emissions continue to rise. The guide advises reporters to examine weather patterns, social determinants of health, and to consult vector biologists.

The document explains how climate change—specifically hotter summers, milder winters, and altered rainfall—is expanding the geographic range and longevity of disease-carrying insects like mosquitoes and ticks. It highlights specific threats in the US, such as the rise of Lyme disease in the Northeast and eastern equine encephalitis in New England, while noting a global risk where over eight billion people could be susceptible to malaria and dengue by the end of the 21st century. The guide advises reporters to examine weather patterns, consider social determinants of health, and consult vector biologists.

The document examines the prevalence of perfluoroalkyl and polyfluoroalkyl substances (PFAS), known as "forever chemicals," in the U.S. environment and population. It details the health risks, including cancer and immune suppression, and outlines the regulatory response led by the EPA's 2021 Strategic Roadmap and the 2024 National Primary Drinking Water Regulation. The brief also covers state-level phase-outs, legislative efforts in the 118th Congress, and technical challenges in remediating PFAS from water and soil.

A coalition of advocates argues that the EPA's disparate impact regulations under Title VI of the Civil Rights Act of 1964 are essential for protecting marginalized communities from disproportionate environmental harms. The document details systemic environmental racism, provides case studies of both successful and failed civil rights enforcement, and urges the EPA to strengthen rather than roll back these protections.

Analysis of 242 U.S. cities shows that fall temperatures have increased by an average of 2.5°F since 1970, with the most intense warming occurring in the Southwest. This trend is characterized by a higher frequency of above-normal temperature days, which prolongs risks related to heat-related illness, wildfires, and allergies, while also affecting agricultural growing seasons and energy demand for cooling.

The report finds that June 2024 was historically hot across the United States, with climate change making temperatures 2.3 times more likely on average. The Southwest experienced the most extreme anomalies, with Nevada's temperatures being 8.2 times more likely due to climate change and the region seeing an average of 4.2 additional days above 90°F. Analysis of 191 ACIS stations showed that 12 experienced their hottest Junes on record, and 168 stations had at least one day where temperatures were at least twice as likely due to climate change.

The report finds that U.S. residential electricity rates have generally kept pace with economy-wide inflation since 2010, and that states with high clean energy growth often see rates rise slower than inflation. Instead, the report identifies natural gas price volatility, wildfire mitigation and liability costs, aging coal plant investments, and rising transmission and distribution costs as the primary drivers of rate spikes. It further argues that the regulated utility business model incentivizes capital-heavy investments over more cost-effective operational solutions, which compounds these costs for consumers.

The Rocky Mountain region (Colorado, New Mexico, Utah, and Wyoming) possesses the feedstocks, industrial infrastructure, and legislative support necessary to develop a sustainable aviation fuel (SAF) industry, yet it currently lacks substantial production. This roadmap examines regional feedstock availability and policy mechanisms to align the region with the US SAF Grand Challenge and outlines actions for short-, medium-, and long-term SAF development.

The Southwest United States experienced an extreme heat event from June 6 to June 13, 2024, with human-caused climate change making high temperatures at least five times more likely. The event caused record-setting temperatures in cities like Phoenix and Las Vegas, led to numerous hospitalizations for heat exhaustion, and contributed to wildfires in California.

The report details significant economic distress in the Navajo Nation, characterized by low median household incomes, high unemployment, and a workforce that must largely seek employment outside the community. While average annual wages have increased, they remain below living wage standards for most industry clusters. The region faces demographic challenges, including a declining youth population and limited housing availability due to complex land-use and leasing requirements.

An analysis of 476 weather stations from 1973 to 2023 shows that fire weather seasons are lengthening and intensifying across the contiguous United States, with the most significant increases occurring in the West. While the East has seen more modest increases, both regions are experiencing a notable rise in fire weather days during the spring. The Southwest has seen the most dramatic growth, with some areas experiencing fire weather twice as often as they did 50 years ago.

The report asserts that Western US states must collaborate on regional electricity transmission expansion to realize significant economic gains. It highlights that energy export states could see their market access grow from $3 billion to $40 billion per year by 2050 with increased capacity, while states with clean energy standards could reduce costs by over 30% through expansive regional planning.

The report argues that reconductoring existing transmission lines with advanced conductors can rapidly increase grid capacity and reduce costs, but is hindered by utility incentive structures, rigid equipment standards, and planning gaps. It recommends aligning utility incentives, updating regional planning horizons, establishing efficiency standards, and expanding federal funding and workforce training to overcome these hurdles.

The report analyzes the federal permitting process for high-capacity electric transmission lines in the U.S., identifying systemic delays caused by poor interagency coordination, capacity shortages, and regulatory misalignment between federal and state authorities. Based on a dataset of 37 projects and case studies, it argues that while litigation is often cited as a primary barrier, it is rarely the sole cause of project failure. The authors recommend that the President prioritize transmission as a national priority, that Congress consolidate siting authority for multi-state projects, and that agencies adopt more agile, transparent, and collaborative environmental review processes, including expanded use of programmatic EISs and categorical exclusions.

The Private Equity Stakeholder Project (PESP) testifies that private equity firms use extractive financial tactics—such as high leverage, sale-leasebacks, and debt-funded dividends—to maximize returns, often resulting in the bankruptcy or closure of hospitals. The document highlights specific cases including Prospect Medical Holdings, Steward Health Care, and Apollo Global Management's Lifepoint/ScionHealth, noting severe impacts on patient safety and staffing. PESP proposes state-level policy solutions including stricter merger reviews, financial transparency, anti-looting measures, and joint and several liability for investors.

To meet its 2045 clean energy goals, California must roughly triple its energy capacity, but faces significant barriers in grid infrastructure, interconnection processes, and land use. The document proposes solutions such as grid-enhancing technologies, interconnection reforms with equity considerations, and incentivizing clean energy on built environments or disturbed lands.

The author argues that food waste is a critical but often overlooked component of climate action plans, noting that food waste in the US generates 170 million metric tons of CO2 emissions annually. The document highlights the EPA's $4.6 billion CPRG program as a key funding opportunity for governments to implement scalable waste reduction projects, citing California's Senate Bill 1383 as a model for curbing organic waste in landfills.

The document details how Yale Climate Connections (YCC) utilizes personal narratives, evidence-based 'climate framing', and diverse voices to bridge the psychological distance of climate change. It emphasizes the use of the 'Six Americas' segmentation to tailor content, the importance of centering hope through problem-solution narratives, and the strategic use of succinct 90-second radio stories to reach a broad national audience, including conservatives and opinion leaders.

The Infrastructure Investment and Jobs Act (IIJA) allocated $12.1 billion to advance carbon management technologies in the United States. Two years into implementation, the Department of Energy (DOE) and Environmental Protection Agency (EPA) have launched several key programs. The Carbon Capture Demonstration Projects Program has selected nine FEED study projects and three demonstration projects, including the Baytown, Project Tundra, and Sutter projects. The Carbon Storage Validation and Testing Program has awarded funding to projects across multiple states, including Texas, Louisiana, and Wyoming, to develop large-scale sequestration and transport infrastructure. Additionally, the EPA has allotted $48 million to 25 state and Tribal recipients to support the regulation of UIC Class VI wells. In the realm of carbon removal, the Regional Direct Air Capture (DAC) Hubs Program has selected two commercial-scale hubs in Texas and Louisiana for award negotiations. The document notes that while progress is underway, agencies have until 2026 to allocate remaining funds, and future success depends on shared transport networks and community engagement.

The report details survey results from the Ironbound Community (New Jersey), Navajo Nation Chapters (New Mexico, Arizona, Utah), and St. James and St. John the Baptist Parishes (Louisiana). It finds widespread skepticism toward developers due to unfulfilled past promises and low initial awareness of CBPs. While support for CBPs increased after residents were informed of potential benefits, priorities varied: environmental quality (water and air) and affordable housing were highly valued, while specific clean energy funding like EV charging stations ranked lower. Residents strongly emphasized the need for transparent, accessible engagement and the inclusion of small business owners and environmental groups in negotiations.
