The document outlines a hierarchy for space cooling, prioritizing the minimization of heat gain through passive measures before investing in mechanical systems. It details various cooling technologies, including fans, evaporative coolers, heat pumps, and air conditioners, providing guidance on their efficiency, costs, and appropriate climatic applications.

The Reefs at Risk Caribbean project workshop focused on improving a threat assessment model for coral reefs using proxy indicators. Key discussions centered on refining data for coastal development, watershed-based pollution, overfishing, and coral bleaching. Participants recommended incorporating higher-resolution data, adjusting population density metrics for fishing pressure, and treating coral bleaching and disease as separate analysis layers rather than integrated threat model components. The workshop also addressed the need for better mapping of Marine Protected Areas (MPAs) and the economic valuation of reefs.

The report analyzes the vulnerability of the Gulf Coast's diverse ecosystems—from upland forests to coral reefs—to rising temperatures and sea levels. It highlights that while climate change poses significant threats to water resources, biodiversity, and public health, current human activities like shoreline development and water engineering remain the primary drivers of ecological change. The authors advocate for a three-pronged strategy of mitigation, minimization of human impacts, and adaptive management to safeguard the region's economic and natural heritage.

The letter from Scientists for Global Responsibility (SGR), UK, argues that the US decision to reject the Kyoto Protocol is irresponsible and threatens millions of lives. The authors contend that the scientific evidence for climate change is robust and that action must be taken based on the best available evidence, even in the presence of scientific uncertainty.

The Center for International Environmental Law (CIEL), representing COICA and the Amazon Coalition, requests the reexamination of U.S. Plant Patent No. 5,751 for the 'Da Vine' cultivar of Banisteriopsis caapi. The request argues that the patent is invalid because the plant's characteristics—specifically its rose-colored flowers—are typical of the species and documented in prior art from U.S. herbaria. Furthermore, the document asserts that the plant is found in an uncultivated state and that granting a patent over a sacred plant used in indigenous Amazonian religious and medicinal traditions violates public policy and international principles like the Convention on Biological Diversity.

The document encourages journalists to link extreme weather events to human-caused climate change, arguing that omitting this connection results in incomplete or inaccurate reporting. It provides specific phrasing for attributing heatwaves and hurricanes to a warming planet and suggests analogies, such as climate change 'stacking the deck' or acting like 'steroids' for weather patterns. The guide addresses common journalistic hesitations regarding activism, deadlines, and scientific attribution, noting that while direct attribution to a single event is complex, the fact that climate change creates conditions making such events more likely is a verifiable fact. It further emphasizes that extreme weather coverage is a key opportunity to educate the public on the urgency of the crisis, particularly in the US, and to highlight how marginalized groups, including Indigenous people and communities of color, are impacted first and worst.

The document examines the application of environmental taxes, fees, and charges across different sectors in the U.S., including water, air, solid waste, and hazardous waste management. It distinguishes between revenue-raising taxes and cost-offsetting fees, noting that while many instruments are designed to recover administrative costs, some—such as the federal tax on ozone-depleting chemicals and certain state-level hazardous waste taxes—have demonstrated significant incentive effects in reducing pollution. The report also details specific state-level experiments with variable-rate waste collection and wetland compensation fees.

FloodVision provides photorealistic, street-level visuals of projected coastal flooding to help the public understand storm surge risks. The tool uses stereoscopic video, LiDAR, and GPS data combined with generative AI to model flood depths above road level, aligning with National Hurricane Center (NHC) forecasts. Beyond immediate storm response, these visuals are intended for long-term resilience planning, such as securing funding and improving zoning decisions. The guide outlines a process for requesting curated visuals and establishes ethical guidelines to protect private property and ensure the tool supplements, rather than replaces, official government guidance.

The report identifies 5,500 hazardous facilities along U.S. coasts at risk of 100-year coastal flooding by 2100 under a high-emissions scenario. It highlights a significant environmental justice gap, finding that poorer and marginalized communities are 15-41% more likely to live near these at-risk sites. The analysis emphasizes the danger of 'NaTech' disasters, where natural events trigger technological failures, leading to toxic contamination of floodwaters.

The document outlines an educational activity where students engage with 90-second radio stories about climate change to learn about its causes, impacts, and solutions. Students are tasked with selecting a story, answering comprehension questions, and then re-representing the information via a poster, brochure, comic strip, or piece of art. The guide emphasizes that science storytelling differs from fiction because it is used as a tool to present observed and measured facts in an accessible manner.

The document details the widespread groundwater and surface water contamination caused by 42 coal ash ponds and 13 landfills across 20 Florida power plants. It highlights specific instances of toxic leakage—including arsenic and lead—at sites such as the C.D. McIntosh, Jr. Power Plant and the Scholz Power Plant. The report further criticizes Florida's regulatory framework for lacking requirements for liners, monitoring, and oversight, particularly regarding the reuse of coal ash in construction materials like "EZBase."

The document evaluates the FDEP's proposed revisions to water quality criteria for 81 harmful chemical substances. It argues that the FDEP's reliance on Monte Carlo simulations is premature and flawed, leading to criteria that are substantially less protective than U.S. EPA recommendations. The author highlights failures to protect sensitive populations, including children and subsistence fishers, and criticizes the proposed compliance monitoring plan as inadequate.

The document outlines the economic and environmental benefits of energy efficiency in Florida, asserting that specific policies could save the state $392 million and avoid 18 million tons of CO2 by 2030.

In 2024, the United States had more than 4,085,300 climate jobs, with clean energy job creation outpacing fossil fuel job creation. Energy efficiency was the largest sector, supporting nearly 2.4 million jobs, while renewable energy supported 596,100 jobs, dominated by solar and wind. Clean energy storage and grid modernization supported 160,300 jobs. Clean vehicle employment fell by 3% between 2023 and 2024, though renewable fuels remained steady. The adaptation and resilience industry grew by 18% to $4.8 billion in 2024, despite a lack of formal tracking by the U.S. Bureau of Labor Statistics. Federal legislation including the Inflation Reduction Act (IRA) significantly drove investment, although some incentives were weakened or eliminated in 2025.

The document details the distribution of Recovery Act funds for high-speed rail awards across the West, Midwest, Southeast, and Northeast regions of the United States. The West region received the highest allocation at $2,942,000,000, followed by the Midwest at $2,599,600,000, the Southeast at $1,870,000,000, and the Northeast at $485,000,000. Key projects include the California High-Speed Rail, the Tampa-Orlando Phase 1 HSR, and various track, signal, and station upgrades across multiple state corridors to increase train speeds and reliability.

The document consists of a collection of 45 figures mapping the FSEIS routes for nuclear waste transport through nearly every U.S. state and the District of Columbia.

The document provides a set of policy recommendations aimed at the 117th Congress to improve coastal resilience in the United States. It emphasizes the integration of climate justice, the use of nature-based solutions, and the necessity of basing federal decision-making on future climate projections rather than historical data. The recommendations are supported by regional models, such as Louisiana's LA SAFE initiative and living shoreline projects in North Carolina, highlighting the need for community-centered planning and updated benefit-cost analysis tools.

The document argues that the One Big Beautiful Bill Act (OBBBA) will negatively impact the U.S. economy, costing households $170 billion in energy bills and reducing GDP by $1.1 trillion by 2035. To counter this, it urges states to reduce clean energy costs by improving siting and permitting, optimizing existing transmission, promoting self-supply for large customers, and enhancing procurement practices.

The document assesses how the COVID-19 pandemic strained sovereign debt management offices (DMOs) in the MEFMI region, highlighting a general lack of comprehensive business continuity plans and procedure manuals. While most countries maintained legal debt limits and audit frequencies, the crisis forced a shift toward remote work and virtual coordination, which increased operational risks and compromised the segregation of duties. The report recommends strengthening operational risk frameworks, investing in digital infrastructure, and introducing 'escape clauses' in regional debt convergence criteria to better handle future crises.

The report analyzes 308 projects totaling over $3.1 billion in IIJA expenditures across California, Colorado, Florida, New York, and Texas. It finds that while significant funds are reaching these states, investments are heavily skewed toward large-scale infrastructure projects managed by the Army Corps of Engineers, with relatively low funding for public lands and greenspaces. The analysis highlights a gap in orphaned well remediation near Latine communities and notes that carbon capture investments in Texas primarily benefit private industry. However, it identifies successes in fenceline air monitoring and climate pollution planning grants that have reached grassroots organizations and Latine-led initiatives.
