In January 2025, 166 out of 191 analyzed U.S. cities were cooler than normal, with the Ohio Valley and Southeast particularly affected. Despite these cool anomalies, no city set a low temperature record for January, and the warming influence of climate change remained pronounced. Alaska was the warmest state, with Fairbanks recording the highest anomaly at 14.6°F above normal. Analysis using the Climate Shift Index (CSI) showed that days where warmer temperatures were made at least twice as likely by climate change outnumbered days where cooler temperatures were made twice as rare.

Analysis by Climate Central shows that all 50 U.S. states and 99% of 242 analyzed major cities have warmed since 1970. Alaska was the fastest-warming state, while Reno, Nevada, experienced the highest city-level temperature increase. The document links these trends to rising greenhouse gas concentrations, which reached 427 ppm of CO2 in 2025, and advocates for the transition to zero-emission vehicles, solar and wind power, and heat pumps to mitigate future risks.

The document outlines how winters are warming faster than any other season in nearly 75% of the United States, leading to significant disruptions in agriculture, health, and the economy. It provides specific regional examples—such as crop failures in Michigan, declining snow crab populations in Alaska, and increased winter tornadoes—while offering professional advice for reporters on handling climate variability and connecting local events to global fossil fuel consumption.

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 guide outlines strategies for educators to embed climate change solutions into diverse subjects, from K-12 to graduate school. Key recommendations include utilizing local examples, inviting diverse guest speakers to demonstrate various career pathways, using simulations and games, and encouraging student-led projects and engagement with local government. The author emphasizes the importance of science-informed optimism and helping students find their personal purpose within the climate movement.

The document outlines how the Energy Infrastructure Reinvestment (EIR) program, part of the US Department of Energy's Title XVII authority, provides low-cost, long-tenor debt financing to help oil and gas companies repurpose ceased operations or reduce emissions from active infrastructure. It details specific transition opportunities across the upstream, midstream, and downstream value chains, such as lithium extraction from brine, enhanced geothermal systems, and the conversion of refineries to sustainable aviation fuel production. The brief emphasizes that the current high-interest rate environment makes this government financing particularly attractive, though the opportunity is time-constrained as loan authority currently expires in September 2026.

The Union of Concerned Scientists (UCS) evaluated 38 federal agencies on their adherence to scientific integrity metrics, finding that 71% scored 'poor' or 'worst'. The report argues that political interference in science disproportionately harms underserved communities and proposes a blueprint for the next presidential administration to strengthen scientific integrity through better policy enforcement, transparency, and the integration of environmental justice principles.

The Center for International Environmental Law examines the "Insuring Our Future Act" (Assembly Bill A9905A/Senate Bill S9435) in New York. The bill targets the contradiction of insurance companies raising premiums due to climate-driven disasters while continuing to finance the fossil fuel industry. It proposes a five-year phase-out of fossil fuel investments and underwriting, alongside protections against "bluelining" and sudden non-renewals for policyholders.

The document examines the structural exclusion of Inuit from Canada's federal climate policy and proposes a shift toward an 'Indigenous resurgence paradigm' to ensure equitable representation. It identifies barriers such as tokenistic engagement and the failure to differentiate between northern and southern regional needs. The study highlights existing frameworks, such as the National Inuit Climate Change Strategy and the Circumpolar Inuit Protocols for Equitable and Ethical Engagement, as essential guides for achieving Inuit-led climate justice.

Using the Climate Shift Index (CSI), Climate Central found that human-caused climate change significantly boosted spring warmth in 2024, affecting 300 million people in the U.S. and approximately one in four people globally. The strongest influence was observed in coastal and island regions, such as Puerto Rico and Florida, while areas with the highest temperature anomalies, like the Upper Midwest, showed lower CSI levels due to higher historical temperature variance.

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 Electric Utility Toolkit explains the technical and regulatory framework of the US power grid, highlighting systemic inequalities in energy access and affordability. It details the role of Public Utility Commissions (PUCs) and provides actionable steps for citizens to engage in the regulatory process to promote energy justice and decarbonization.

The document describes La Niña as the cool phase of the El Niño-Southern Oscillation (ENSO) cycle, characterized by the movement of cold water to the central and eastern Pacific surface. For 2024, there is an 85% chance of a transition to neutral conditions between April and June, and a 60% chance of La Niña developing by June to August. The text highlights that multi-year La Niña events are increasing in frequency, with five of the last ten occurring in the past 25 years. While La Niña temporarily lowers global average surface temperatures by about 0.1C, it does not offset human-caused warming; recent La Niña years have been among the top 10 hottest years ever. Regional impacts include drier conditions in East Africa and the southern US, and wetter conditions in Southeast Asia, India, and northern South America, affecting various crop yields and increasing the risk of floods and droughts.

Climate change is increasing the intensity of extreme precipitation across the U.S., with the Northeast and Midwest seeing the largest increases since 1958. Under 2°C of global warming, 85% of U.S. counties are projected to experience a 10% or higher increase in precipitation on the heaviest 1% of days. This intensification contributes to flash flooding and landslides, disproportionately affecting racial minorities and those in mobile homes, particularly in the South and rural areas. Between 1988 and 2021, warming-induced rainfall intensification caused an estimated $84 billion in inland flood damages.

Since 1970, 98% of analyzed U.S. cities and all 50 states have warmed, with Reno, Nevada and Alaska experiencing the fastest increases. To combat this, U.S. clean technology investment reached a record $239 billion in 2023, more than tripling since 2018, with South Carolina and Nevada leading in investment as a percentage of GDP, primarily driven by battery manufacturing.

Six Alaskan children sued the State of Alaska, arguing that the state's failure to limit greenhouse gas emissions violated the public trust duty established in Art. VIII of the Alaska Constitution. The Superior Court of Alaska dismissed the case in 2012, ruling it non-justiciable as it involved political questions. The Supreme Court of Alaska affirmed the dismissal in 2014, though it differed in reasoning, concluding that a declaratory judgment would not settle the dispute as it would have no impact on the state's conduct or emissions.
