The document argues that rising sea levels and extreme coastal flooding threaten approximately 2,000 Superfund sites along the US East and Gulf Coasts, potentially releasing hazardous chemicals into nearby communities. It highlights that these risks disproportionately affect communities of color and low-income households, who are more likely to live near these sites. The authors criticize the Trump administration for sidelining climate science and rescinding resilience-focused executive orders, and they recommend a new executive order and interagency coordination to integrate climate science into Superfund site risk assessments.

The document describes a two-part methodology: first, using a "bathtub model" combining Digital Elevation Models, tidal gauge data, and NOAA sea level rise projections to map future 100-year-flood zones; second, performing a buffer analysis around 9,689 Superfund sites to determine if people of color and low-income households are disproportionately located near sites at risk of flooding.

The document analyzes how environmental degradation, the pursuit of civilian nuclear power, and geopolitical tensions—primarily involving China—intersect to create instability in the South China Sea region. It highlights the vulnerability of Indonesia and the Philippines to sea-level rise and extreme weather, their efforts to establish nuclear energy frameworks via IAEA guidance, and the internal threat posed by ISIL-affiliated extremists. The report argues that these converging risks, combined with hegemonic competition between the U.S. and China, threaten regional stability.

Dr Samuel Morin explains the importance of 'unpacking' the IPCC SROCC's Summary for Policy Makers (SPM) by using concrete, local examples—such as ski tourism, sea level rise, and mountain gravitational hazards—to make global findings relevant to French national policy-makers. He emphasizes that spending significant time clarifying basic climate principles and scenarios is a prerequisite for effectively discussing specific risks and impacts.

Dr Alex C. Ruane, an IPCC author, details his method of translating complex climate data into accessible information for community groups in Manhattan. He emphasizes moving from abstract metrics, such as CO2 concentrations, to tangible impacts on food and cities, and utilizes specific analogies—such as comparing sea level rise to raising a basketball court floor—to make scientific uncertainties and risks more comprehensible to non-experts.

Dr Masao Ishii, an author for the IPCC Sixth Assessment Report, utilizes specific observations from Japan's coastal sites and the western North Pacific—such as sea level rise, sea surface temperature, and acidity—to illustrate the connection between local experiences and the global climate system. He notes that presenting these regional examples helps audiences grasp the complexity and uncertainty of future projections. Furthermore, engaging with a diverse audience, including the general public and climate skeptics via platforms like YouTube and Slido, has prompted him to broaden his own knowledge and consider the varied implications of climate data for different stakeholders.

The briefing discusses strategies for enhancing resilience in the U.S. Caribbean, focusing on Puerto Rico's transition toward a renewable energy economy centered on rooftop solar and the U.S. Virgin Islands' efforts to integrate natural infrastructure into hazard mitigation plans.

The 2020 Atlantic hurricane season was predicted to be more active than normal due to warmer-than-average water temperatures in the Atlantic and Gulf of Mexico and ENSO-neutral conditions. While climate change may not increase hurricane frequency, it is linked to a 25-30% increase in Category 4 and 5 storms per degree Celsius of warming, more rapid intensification, increased rainfall, and higher storm surges driven by rising sea levels.

The document is a transcript of a briefing featuring experts from the U.S. House Committee on Natural Resources and the Puerto Rico Department of Natural and Environmental Resources. It examines the devastating impacts of Hurricanes Irma and Maria, as well as recent earthquakes in Puerto Rico, highlighting the vulnerability of the electric grid and coastal infrastructure. The speakers argue that while Congress has approved significant funding for recovery and resilience, bureaucratic delays in federal agencies like HUD and FEMA have stalled the disbursement of these resources. The briefing emphasizes the effectiveness of nature-based solutions, such as coral reef restoration, for wave attenuation and coastal protection, while noting that traditional cost-benefit analysis tools often favor short-term returns over long-term resilient infrastructure.

The report uses the Sustainable Asset Valuation (SAVi) tool to quantify the economic importance of the Saloum Delta's wetlands and mangroves. It compares a business-as-usual (BAU) scenario against interventions such as organic agriculture, mangrove reforestation, road construction, solar cookstoves, and oil extraction. The analysis highlights a significant trade-off: while oil extraction generates massive near-term revenues, it causes substantial losses in ecosystem services. Conversely, nature-based interventions like mangrove restoration and organic agriculture provide long-term economic gains through enhanced ecosystem performance and labour income. The report also proposes blended finance strategies, including carbon offsets and impact bonds, to fund conservation.

The document investigates the integration of the private sector into Vietnam's National Adaptation Plan (NAP). It highlights that while the private sector is a critical source of funding and innovation, current policies often view businesses as entities to be managed rather than partners. The report identifies significant gaps in climate risk awareness and financial resilience among small and medium enterprises (SMEs) and proposes specific strategies, including public-private partnerships (PPPs), green bonds, and tailored insurance products, to incentivize private investment in climate adaptation across various economic sectors.

The authors highlight the accuracy of previous intelligence warnings regarding pandemics to argue that similar foresight must be applied to climate change. They assert that unabated climate change will trigger global instability through food and water insecurity, mass migration, increased international tensions, and high-impact 'wildcard' events, necessitating a move toward net-zero emissions to protect global security.

The document examines how the COVID-19 pandemic and climate change concurrently degrade the readiness of the U.S. Department of Defense (DoD). It highlights the financial and operational strain caused by severe weather, specifically citing the $3.6 billion in damages to Marine Corps Base Camp Lejeune from Hurricane Florence. The author contends that the DoD should apply the same decisive adaptation strategies used to combat COVID-19 to mitigate long-term climate risks, such as recurrent flooding and wildfires, to ensure national security and deter adversaries.

The report identifies critical vulnerabilities in Ghana's infrastructure due to rising temperatures, variable rainfall, and sea-level rise. It proposes a comprehensive set of technical and policy adaptations across the water, energy, and transport sectors, emphasizing inter-ministerial collaboration, gender-responsive planning, and the need for sustainable domestic and international financing.

The document examines the postponement of critical 2020 ocean governance negotiations due to COVID-19, highlighting the urgent need for integrated climate and biodiversity action to prevent marine ecosystem collapse.

Turkey is pursuing a civilian nuclear energy program to diversify its energy sources and meet rapidly growing electricity demand, primarily through the Akkuyu Nuclear Power Plant developed with Russia under a 'build-own-operate' (BOO) model. While Turkey adheres to international nonproliferation regimes and collaborates with the IAEA, the BOO model creates risks regarding regulatory oversight, information asymmetry, and potential safety compromises to reduce costs. Additionally, Turkey faces significant climate security threats, including drought and sea-level rise, which may impact the operation of its coastal nuclear sites. The program also reflects Turkey's complex strategic balancing between Russia and NATO allies.

The document emphasizes that local policymakers struggle to act on climate information that is not location-specific. To address this, Climate Central provides two tools: the Coastal Risk Screening Tool, which allows users to explore coastal flood and sea-level rise risk by year or water level, and Risk Finder, which provides data on at-risk populations and facilities for states, counties, and Congressional districts. These tools utilize data from approximately 110 databases, including various U.S. federal agencies such as NOAA, USGS, and FEMA.

The document describes a vulnerability assessment protocol developed for the National Park Service (NPS) to evaluate coastal infrastructure risks. The assessments focus on physical exposure and characteristics, helping managers decide whether to protect, move, or decommission assets. While sea level rise models projected to 2050 are used, the text notes that hurricanes at current sea levels contribute significantly to exposure scores. Practical applications include raising utilities in Florida and incorporating local perspectives at Cumberland Island National Seashore.

The document outlines the critical role of up-to-date data in understanding Earth processes and managing climate risks. It highlights the use of LiDAR for flood mapping via the 3-Dimensional Elevation Program, the importance of NOAA's hydrologic and coastal data, and the role of the Earth Prediction Innovation Center in extreme weather forecasting. It also emphasizes the value of NASA and NOAA's planetary-scale satellite observations and the potential for artificial intelligence to enhance disaster prediction and community resilience through the proposed National AI Initiative.

Washington Sea Grant developed a localized sea level rise assessment for Washington State to bridge the 'action gap' between the perceived importance of climate impacts and the availability of planning tools. The project introduced a probabilistic framework for communicating uncertainty and integrated vertical land movement data to create site-specific relative sea-level projections. These data were delivered via an interactive map and a Tableau-based tool. Implementation efforts included pilot projects in Tacoma and Island County, where the data informed the redesign of Owen Beach, the visioning of a linear park, and the creation of a community-based coastal resilience planning guide for shoreline homeowners.
