New research from Climate Central indicates that climate change accounted for 27% of the rate of heat-related emergency room visits in the U.S. during the warm seasons from 2018 to 2025. The study found that all U.S. regions experienced increased visit rates due to climate change, with the highest rates occurring in southern and western states. A notable peak occurred during the June 2021 northwestern U.S. heat wave, where daily visit rates were approximately 50 times higher than the regional average, with 27% of that rate attributed to climate change.

The report argues that while next-generation geothermal has vast potential to provide clean firm power, its growth is hindered by a 'missing middle' financing gap, subsurface uncertainty, and outdated regulatory frameworks. It proposes five deployment levers: characterizing subsurface resources through data digitization and mapping, governing through streamlined permitting and clarified property rights, financing via procurement standards and convertible loans, connecting through improved transmission planning and workforce development, and innovating through sustained R&D and testbeds.

The report analyzes the strategic use of joint ventures by private equity (PE) firms to enter healthcare markets, leveraging the reputation of nonprofit partners to scale operations. Through case studies of Lifepoint Health, Ascension, Compassus, and Ardent Health, it documents patterns such as sale-leaseback real estate transactions, the use of nonprofit referral networks, and declining care quality. It argues that current IRS and state regulations are insufficient to oversee these complex structures and recommends expanded oversight of management fees, control rights, and charitable asset transfers.

This fact sheet from the Environmental and Energy Study Institute describes the role of cobalt as a critical mineral for the clean energy transition, detailing its applications in lithium-ion batteries, global distribution of reserves and production, and the significant human rights and environmental impacts associated with its extraction, particularly in the Democratic Republic of the Congo.

As of March 30, 2026, the western U.S. is experiencing a historic snow drought, with snow water equivalent at its lowest record for April 1 and 65% below the 1991-2020 normal. This condition is attributed to a record-warm winter and a record-shattering March heat wave fueled by heat-trapping pollution. Long-term trends from 1955 to 2023 show an 18% average decline in April 1 snowpack across 652 monitoring stations, with snow droughts growing 28% longer between 1980 and 2018. These trends increase risks for water supplies, hydropower, and wildfires, with projections suggesting a further 25% decline in snow water equivalent by 2050.

In 2025, the contiguous U.S. experienced its fourth-warmest year on record and 23 billion-dollar weather and climate disasters, totaling $115 billion in damages. Globally, 2025 was the third-warmest year since 1850, with NOAA data indicating it was approximately 1.3°C warmer than the pre-industrial average. The year was marked by record-breaking December heat in the U.S. Southwest and devastating atmospheric river flooding in Washington and Oregon.

The document reports that November 2025 was the third warmest on record globally and the fourth warmest for the contiguous U.S. It highlights a long-term trend of warming winters in the U.S., where the coldest day of the year has warmed by approximately 7°F since 1970. The briefing also notes significant regional anomalies, such as extreme warmth in Texas and heavy rainfall in southern California, while discussing the ongoing La Niña advisory and its expected impacts on weather patterns through early 2026.

The Mona to Oquirrh transmission line, a 100-mile project completed in 2013, faced significant opposition from Tooele City due to a lack of early community engagement and a proposed route that threatened a valued viewshed. Despite initial refusals by Rocky Mountain Power (RMP) to reroute, the City used its ownership of a small portion of the land to launch legal challenges, including a temporary restraining order. This forced RMP into negotiations, resulting in a January 2011 settlement where RMP agreed to reroute the line behind the mountains and provide community benefits, including the purchase of 130 acres of open space and a $500,000 contribution to the Skyline Nature Park.

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 document examines how climate change is creating a home insurance crisis in the U.S., characterized by skyrocketing premiums and widespread policy non-renewals. It asserts that 'Big Oil' companies, who knew about the risks of fossil fuels as early as 1954, are responsible for these conditions. The report highlights specific state-level crises in Florida, California, and Hawaiʻi, and advocates for policy solutions—such as subrogation and legislative surcharges—to shift the financial burden from policyholders to the fossil fuel industry.

The Private Equity Detention and Surveillance Tracker details the involvement of private equity firms in the US mass incarceration system, covering facility management, healthcare, food services, telecommunications, and surveillance tools. It highlights how profit motives lead to cost-cutting in critical services, high markups on basic necessities, and the deployment of controversial surveillance technologies.

In February 2025, U.S. temperature anomalies were split, with 92 cities warmer and 99 cooler than the 1991-2020 normal. Despite an average anomaly of -0.3°F and significant cold in the Northern Rockies and Plains, no city set a low temperature record for the month. Conversely, Phoenix, Arizona, recorded its hottest February on record. Analysis using the Climate Shift Index (CSI) indicates that temperatures in many cities remained warmer than they would have been without climate change, as more cities experienced days with positive than negative CSI values. Long-term trends show that 189 out of 191 analyzed stations have warmed since 1970, with Juneau, Alaska, being the fastest-warming station for February.

RMI outlines five key factors—facility suitability, electricity costs/net metering, energy efficiency, battery sizing, and available funding—to help US communities deploy solar-plus-battery microgrids that serve as resilience hubs during disasters.

The document examines the financial mechanisms of utility regulation, specifically the gap between the allowed return on equity (ROE) and the cost of equity (COE). It argues that current ROEs are excessively high, creating a 'capex bias' that incentivizes expensive capital projects over cost-effective solutions like energy efficiency. By analyzing price-to-book ratios and applying discounted cash flow models, the authors estimate that the required return for investors is significantly lower than currently approved rates. The guide provides a framework for stakeholders to challenge inflated COE estimates by correcting flawed model assumptions regarding interest rates, growth rates, and historical means. It further dismisses common industry claims that lower ROEs would limit access to capital or increase customer costs via credit rating downgrades.

The four lower Snake River dams cause an average additional water loss of approximately 30,000 acre-feet per year due to evaporation compared to free-flowing conditions. This loss is valued at roughly $110 million as a water right and is equivalent to the water needed to grow 8,000 acres of apples or supply the household needs of 240,000 people. Future projections (2025–2055) suggest these losses will persist or slightly increase, ranging from 30,100 to 32,800 acre-feet per year across eight global climate models.

The petition argues that the 1993 Recovery Plan's compartmentalized approach of managing grizzly bears in isolated recovery areas is outdated and fails to ensure long-term genetic and demographic resiliency. It proposes a unified metapopulation framework that manages bears as a single interconnected population across the Northern Rockies, requiring the establishment of natural connectivity and the implementation of stricter regulatory mechanisms to reduce human-caused mortality. The petitioners oppose current efforts by Idaho, Montana, and Wyoming to delist grizzly bears, asserting that recovery is premature without a connected metapopulation and durable protections against threats such as habitat fragmentation, climate change, and lethal management policies.

Small modular reactors (SMRs) are emerging nuclear energy technologies producing 300 MW or less, offering a potential source of reliable, emission-free electricity for Canada's energy transition. While Canada possesses a strong nuclear industry and uranium reserves, SMRs are currently classified as a 'wild-card' technology due to high costs, regulatory hurdles, and a lack of commercial viability. Despite these challenges, several Canadian provinces and the federal government are investing in SMR development, with projects planned for Ontario, Saskatchewan, and New Brunswick.

Earthjustice reports a series of legal victories in 2024, including a landmark settlement to decarbonize Hawaii's transportation system by 2045, the cessation of coal leasing in the Powder River Basin, and a historic Inter-American Court of Human Rights ruling requiring Peru to remediate lead pollution in La Oroya. The organization also secured wins against cryptomining operations in New York, fossil fuel infrastructure expansion in New Jersey, and the loss of wetlands protections following the U.S. Supreme Court's Sackett v. EPA decision, notably helping Colorado pass legislation to reinstate wetland protections in May 2024. Additionally, the report highlights efforts to regulate PFAS in plastic containers, limit lead wheel weights, and protect endangered species such as the Cook Inlet beluga whale and Pacific sardine.

The document outlines a four-step process for utility climate risk planning: identification, quantitative assessment, mitigation, and risk distribution. It emphasizes the need for utilities to move beyond siloed resilience plans by incorporating both physical risks (e.g., extreme weather) and transition risks (e.g., carbon taxes, policy changes) into core planning documents like Integrated Resource Plans (IRPs). The authors advocate for the use of high-resolution, long-term climate datasets (30+ years) to accurately model extreme events and argue that clean energy portfolios reduce financial volatility for residential customers compared to fossil-heavy portfolios. Finally, it provides actionable recommendations for regulators to mandate risk assessments, create financial incentives for transitioning away from fossil assets, and explore self-insurance funds to protect low- and middle-income customers from catastrophic costs.

A coalition of national and regional organizations is calling on Utah's House representatives to support S. 3853, the Radiation Exposure Compensation Reauthorization Act, noting that for the first time since 1990, affected downwinders and uranium miners lack access to compensation and cancer screenings.
