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.

The document analyzes the emergence of 'equity PIMs'—regulatory tools that provide financial rewards or penalties to utilities based on their performance regarding equity metrics. It identifies seven US jurisdictions using these tools to address energy poverty and the inequitable distribution of clean energy benefits. The report distinguishes between program-based and outcome-based PIMs, discusses the role of reporting metrics and scorecards as precursors to financial incentives, and argues that PIMs must be part of a broader regulatory strategy including cost-control reforms and low-income assistance to be effective.

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.

The report finds that private equity-owned companies accounted for approximately 21% of all healthcare bankruptcies in 2023, with a further wave expected in 2024. It attributes this trend to the private equity business model's reliance on excessive leverage, dividend recapitalizations, and aggressive growth strategies, which leave companies vulnerable to rising interest rates and labor costs. Case studies of firms like Envision Healthcare and Air Methods highlight how the No Surprises Act further impacted companies reliant on surprise billing. The report warns that these financial failures lead to service closures, layoffs, and threats to publicly-funded healthcare infrastructure.

The document outlines the technical framework for assessing electric vehicle (EV) benefits, utilizing EPA eGRID data for power plant emissions and the GREET model for upstream feedstock emissions. It specifies the use of a sales-weighted EV efficiency of 0.314 kWh/mile and an average annual mileage of 11,599 miles. Public health benefits are derived from the American Lung Association's use of the EPA COBRA model, while economic data includes announced manufacturing jobs from the EV Jobs Hub and charging infrastructure growth from the Alternative Fuels Data Center. Fuel cost comparisons rely on NREL utility rates and GasBuddy gasoline prices.

The EESI 2023 Climate, Environmental, and Energy Congressional Hearings Tracker catalogs hearings across numerous House and Senate committees. House activity was led by the Natural Resources (28 hearings) and Energy and Commerce (24 hearings) committees, focusing on energy security, grid reliability, and critical minerals. Senate activity was prominent in the Environment and Public Works (22 hearings) and Budget (10 hearings) committees, with a strong emphasis on the economic costs of climate change, infrastructure resilience, and the implementation of the Inflation Reduction Act and Infrastructure Investment and Jobs Act.

The report details how Hawaii is experiencing accelerating climate crises, specifically through extreme drought, intense tropical storms, sea level rise, and increasing temperatures. It provides comprehensive lists of potential costs for mitigation and adaptation, ranging from water management and wildfire suppression to floodproofing infrastructure and public health interventions.

An analysis of 2020 Residential Energy Consumption Survey data reveals that extremely low-income US households—those earning less than 30% of the state median income—face a disproportionately high average energy burden of 14%, exceeding the 10% threshold for energy poverty. The report highlights that the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act could save American families approximately $38 billion on electricity bills through technology upgrades and rebates. It identifies successful state-level interventions, such as California's percentage of income payment plans (PIPPs) and Colorado's low-income community solar programs, as models for alleviating energy poverty. The analysis further notes that extremely low-income households in southern states experience the highest energy burdens, often correlating with higher income inequality and diversity indices. The document concludes that states can simultaneously pursue decarbonization and energy affordability, citing Colorado and Washington as examples of states integrating specific energy affordability policies into their climate targets.

The document reports that 2023 is virtually certain to be the hottest year on record, with global surface temperatures from January to November 2023 ranking highest in the 144-year record at 1.4°C above the 1881-1910 baseline. In the U.S., 25 billion-dollar weather and climate disasters occurred between January and November 2023, surpassing the previous annual record of 22 in 2020. These events caused an estimated 482 deaths and $81 billion in damages, with severe storms accounting for 76% of these disasters. The average time between such disasters in 2023 dropped to 10 days, compared to 82 days in the 1980s.

The methodology involves isolating specific federal agency lands in the contiguous US, intersecting these areas with resource suitability data from the Princeton Net Zero America Study and the Global Heat Flow Database, and applying conservative and optimistic capacity density estimates to calculate total gigawatt (GW) hosting capacity across four scenarios.

The period from November 2022 to October 2023 was the hottest 12-month stretch in recorded history, with a global average temperature 1.32°C above the pre-industrial baseline. Using the Climate Shift Index (CSI), Climate Central found that 90% of the global population (7.3 billion people) experienced at least 10 days of temperatures very strongly affected by climate change (CSI level 3 or higher). Approximately 1.9 billion people (24%) experienced a five-day heat wave strongly influenced by carbon pollution (CSI level 2 or higher). The report highlights an inequitable distribution of impacts, with small island developing states and least developed countries facing higher exposure, although heat waves also occurred in G20 nations. The analysis also links human-induced climate change to severe weather events, including deadly flooding in Africa and Libya, and record-breaking wildfires in Canada and Hawaii.

The document reports that the average person in the U.S. breathed more harmful wildfire smoke in 2023 than in any year since 2006, driven largely by record-shattering wildfires in Canada. It details how fine particle pollution (PM2.5) from these fires travels thousands of miles, affecting every county in the contiguous U.S. and stalling air quality improvements in 30 states. The text links these trends to a warming climate and increasing 'fire weather,' noting that human-caused climate change accounts for at least two-thirds of the rapid increase in fire weather in the western U.S.

The document uses the example of international firefighters collaborating to fight Canadian wildfires as a metaphor for the necessary global cooperation required to address climate change and biodiversity loss. It highlights recent multilateral successes, such as the Convention of Biological Diversity COP15 agreement, the Global Biodiversity Framework Fund, and the UN Treaty of the High Seas, as evidence of a positive trend in environmental diplomacy. The author emphasizes the ecological importance of the boreal forest, which contains 20 percent of the world's carbon, and calls for continued partnership between governments, Indigenous Peoples, and civil society at the Seventh GEF Assembly.

The report finds that electric vehicle (EV) drivers in all U.S. states can expect cost savings per trip and annually compared to gas vehicle drivers. The highest savings occur in Washington State due to high gasoline prices and low residential electricity rates, while the lowest savings are found in Hawaii due to higher electricity costs. The analysis focuses on three vehicle classes—sedans, SUVs, and trucks—using 2023 base models and a mix of home and public charging data.

Earthjustice is calling for a moratorium on deep seabed mining, arguing that the ecological impacts of untested mining technologies on deep-sea ecosystems and the climate are unknown. The organization highlights the risk to Indigenous Pacific Islander communities and supports U.S. legislation, including the International Seabed Protection Act, to prevent mining in American and international waters. Earthjustice advocates for a circular economy based on reducing, reusing, and recycling minerals as a sustainable alternative to deep-sea extraction to meet the demand for clean energy technologies.

RMI organized Solarize cohorts in 2021 and 2022 involving 27 U.S. cities to make rooftop solar more accessible to low- and moderate-income (LMI) communities. By combining bulk purchasing discounts with grants and community partnerships, the program helped nearly 1,200 households install over 10 MW of residential solar, with 40% of participants from LMI or BIPOC communities. These installations are projected to save households over $8 million and avoid 106,000 tons of CO2 emissions over 25 years.

The briefing advocates for a global Fossil Fuel Non-Proliferation Treaty based on three pillars: ending new exploration and production, phasing out existing production equitably, and enabling a just global transition. It outlines the necessity of international coordination to address the supply side of climate change, noting that current global production plans exceed 1.5°C limits. The document provides a roadmap for governments to support the treaty through public endorsements, diplomatic engagement, and domestic policy measures such as removing subsidies and restricting new infrastructure.

The briefing advocates for a Fossil Fuel Non-Proliferation Treaty based on three pillars: non-proliferation of new fossil fuels, a fair phase-out of existing production, and a global just transition. It positions the treaty as a necessary supply-side complement to the Paris Agreement, arguing that current production plans exceed the 1.5°C carbon budget. The document outlines a business case for support, citing risks such as stranded assets and increased climate litigation, while proposing specific actions for companies, including public advocacy and the implementation of absolute emission reductions.

Since 1970, all 50 U.S. states and 241 analyzed cities have warmed, with the contiguous U.S. increasing by 2.5°F. While states reduced greenhouse gas emissions by an average of 19% between 2005 and 2020, the current pace of reduction is insufficient to meet the national target of a 50% reduction by 2030.

The document analyzes how warming average annual minimum temperatures in the U.S. are shifting plant hardiness zones northward, affecting the geographic range of crops, invasive species, and pests. Based on an analysis of 242 U.S. locations from 1951 to 2022, it finds that 95% of these locations experienced warming, with some cities seeing significant zone shifts. This trend may expand the range of high-value crops but also facilitates the spread of invasive species like Kudzu and the brown marmorated stink bug.
