Human-caused climate change is increasing the frequency and intensity of wildfires in the U.S., exposing millions of homes and hundreds of thousands of miles of roads and power lines to risk. Approximately one-third of U.S. homes and 116 million people are located in counties with high or very high wildfire risk, with the highest concentrations in Western states and Florida. Between 2000 and 2019, over 265,000 miles of roads and power lines in the contiguous U.S. were exposed to large fires. The risk is further amplified by the expansion of the wildland-urban interface, which grew by about 31% between 1990 and 2020.

The report finds that July 2024 temperatures were elevated in the eastern and western thirds of the United States, with the West Coast showing particularly high anomalies. Using the Climate Shift Index (CSI), the analysis identifies the Southwest as having the strongest climate signal, with cities averaging at least 14 days where temperatures were at least three times more likely due to climate change. Specific cities like Spokane, Washington, and Reno, Nevada, showed significant temperature anomalies and long-term warming trends since 1970.

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.

Analysis of 240 U.S. weather stations shows that 86% of locations have experienced an increase in unusually warm winter days since 1970, with the most significant rises occurring in the Upper Midwest, Southeast, and Northeast. Winter is the fastest-warming season for 74% of the analyzed locations. These trends are accompanied by a decrease in freezing nights, shorter cold snaps, and a rise in the temperature of the coldest day of the year. The document notes that winter warming affects agriculture, water supplies, public health via allergy and mosquito seasons, and winter sports.

Since 1970, the coldest day of the year has warmed by an average of 7°F across 242 U.S. locations, with 97% of locations seeing a rise of at least 1°F. Winter cold snaps have also become shorter, decreasing by an average of six days in 97% of 244 analyzed locations. The most significant warming of coldest days occurred in the Ohio Valley (8.7°F) and Northwest (8.4°F) regions, with the highest individual increases recorded in Boise, Idaho (15.7°F) and Las Vegas, Nevada (14.3°F). These trends contribute to longer allergy and growing seasons, disrupted crop chill requirements, and altered water supplies.

In 2023, the contiguous U.S. experienced its 5th-hottest year on record, with an annual average temperature 2.4°F above the 20th century average. The year saw a record 28 billion-dollar disasters, resulting in an estimated 492 lives lost and over $93 billion in damages. Severe storms were the primary driver, accounting for 68% of these events. The frequency of such disasters has increased significantly, with the average time between events dropping to 12 days in 2023, compared to 82 days in the 1980s.

In 2024, WRI supported over 150 U.S. cities and counties in accelerating clean energy deployment and helped over 60 cities claim more than $12 million in tax credits via the Inflation Reduction Act's elective pay mechanism. The organization advanced next-generation geothermal technologies, launched a database of 50 community benefits frameworks for transmission projects, and supported the deployment of electric school buses (ESBs) through initiatives like the RVXDS project in California. WRI also focused on reforming power markets and grids, providing technical assistance to the PJM Cities and Communities Coalition and researching interregional transmission procurement.

The Biden administration has announced a plan to restore endangered salmon and steelhead in the Pacific Northwest, committing over $500 million in federal funding and support for clean energy projects to replace the services of four dams on the lower Snake River. This plan aligns with the Columbia Basin Restoration Initiative (CBRI), which calls for breaching the dams within two fish generations. Earthjustice and several Native tribes and states have paused litigation against the government to allow for the implementation of these commitments, though final dam breaching will require Congressional action.

The Earthjustice Northern Rockies office focuses on protecting biodiversity, safeguarding sacred Indigenous lands, defending water quality, and transitioning from fossil fuels to renewable energy through litigation and partnerships in Idaho, Montana, and Wyoming.

The 2022 French nuclear outages were caused by a confluence of pipe corrosion, workforce shortages, and heat-related river curtailments, rather than inherent flaws in nuclear technology. The author argues that these issues can be mitigated through standardized reactor designs, consistent government policy to maintain a skilled workforce, and technical cooling upgrades. Despite the 2022 dip in availability, the document asserts that nuclear energy provides essential 'clean firm' power necessary for the cost-effective decarbonization of the European electricity grid.

In 2022, the U.S. experienced 18 billion-dollar weather and climate disasters causing $165 billion in damages and 474 deaths, with Hurricane Ian being the costliest hurricane on record. The year was the 18th hottest on record for the U.S., with 73% of analyzed locations experiencing warmer-than-normal temperatures. These events are part of a longer warming trend, with 98% of analyzed U.S. locations showing increased average annual temperatures from 1970 to 2021. Meanwhile, U.S. fossil fuel emissions increased by 1.5% in 2022, though the Inflation Reduction Act is expected to help double annual wind and solar PV capacity additions by 2027 compared to 2021.

The document reports that 97% of 246 analyzed U.S. locations experienced an increase in average temperature during the period from December 25 to January 5 between 1969 and 2021. It details regional shifts in snowpack and precipitation, noting that winter is the fastest-warming season for most of the U.S., which increases the likelihood of precipitation falling as rain rather than snow.

Georgia electricity customers face high energy burdens, particularly low-income households and people of color, despite relatively low electricity rates. The document identifies several regulatory levers the Georgia Public Service Commission (PSC) could use to lower costs, including reducing Georgia Power's return on equity (ROE) to the national average, implementing fuel-sharing mechanisms to mitigate natural gas price volatility, and updating the Integrated Resource Plan to incorporate Inflation Reduction Act incentives. It also suggests securitization as a means to save customers $1.05 billion and recommends comprehensive transmission and distribution planning to avoid unnecessary capital-intensive spending.

The report examines the intersection of the U.S. nursing shortage and private equity's expansion into travel nursing. It argues that while the pandemic exacerbated staffing issues, structural problems and profit-seeking by hospitals created a vulnerability that travel nursing agencies and private equity firms have exploited. The document details how private equity firms use leveraged buyouts and dividend recapitalizations to extract value from staffing agencies, while agencies have seen profit margins grow from 15% in 2019 to 62% in 2022. It also covers legislative efforts to address price gouging and the push for mandated staffing ratios.

The policy brief examines the impact of high-severity wildfires on the U.S. forest carbon sink, noting that forests in several Western states have become net carbon emitters. It advocates for scaling up 'fuel load treatments'—such as prescribed burns and mechanical removal of biomass—to mitigate wildfire risk and suggests developing markets for thinned biomass (e.g., biochar, green hydrogen) to fund these efforts and reduce emissions. The brief calls for federal policy support via the 2023 Farm Bill to increase research, support rural and Tribal communities, and incentivize innovative wood products.

Climate Central analysis reveals that 83% of 241 analyzed U.S. cities saw an increase in summer stagnant days between 1973 and 2021, with a strong positive correlation between these events and rising summer high temperatures. Annual stagnation has also increased in 81% of these cities, with hotspots in Southern Texas and coastal California. These trends are expected to worsen with climate change, potentially adding up to 40 more stagnant days per year by late-century, which traps pollutants and disproportionately affects communities of color due to historical housing policies.

The report examines the transition to regenerative agriculture across four case studies (Braga Fresh, Fresh Del Monte, Shepherd’s Grain, and Zirkle), finding that while regenerative practices can reduce input costs and improve soil health, they often lead to higher initial food losses. It argues that 'circularity'—measuring and repurposing on-farm loss—is essential to mitigate these risks and boost economic resilience. The document highlights a disconnect between buyer demands for sustainable produce and their unwillingness to pay price premiums or adjust strict cosmetic specifications, which hinders the scaling of regenerative practices.

To meet its 2030 climate target of reducing net emissions by 50-52% from 2005 levels, the United States must increase its land carbon sink's annual removal by 13% over 2019 levels, reaching at least 913 Mt CO2e. The World Resources Institute identifies three primary pathways to achieve this: reforestation and restocking, agroforestry, and wildfire risk mitigation. Together, these pathways would require a total federal investment of $126.6 billion over 20 years, supporting approximately 199,000 jobs annually and generating $226.8 billion in value added to local economies. The document advocates for the Bipartisan Infrastructure Deal and the Build Back Better Act to maintain robust funding for these initiatives to catalyze a just, low-carbon economy.

Phosmet is a U.S. registered pesticide used in 40 states, primarily on orchards and grapes, and is currently under registration review. It is associated with serious health effects, including cancer, neurodevelopmental harm, and reproductive toxicity, with exposure occurring via food, drinking water, and occupational contact. The pesticide is applied to a significant percentage of several common crops, including peaches (55%) and nectarines (50%).

The document argues that U.S. nuclear policy is currently operating in an "information vacuum," with the Nuclear Regulatory Commission (NRC) often prioritizing licensee cost-savings over public safety and environmental data. It highlights systemic risks in "fast-track" decommissioning, the vulnerability of thin-walled spent fuel canisters to corrosion and failure, and the lack of scientific evidence supporting 80-year license extensions for aging plants. The authors further caution against the deployment of small modular reactors (SMRs) and the establishment of consolidated interim storage facilities (CISFs) without comprehensive risk and cost analyses. The briefing concludes with ten recommendations to policymakers, including mandating ASME N3 standards for waste containers, requiring "hot cells" for repackaging damaged fuel, and reforming NRC oversight to reduce regulatory capture.
