The Union of Concerned Scientists (UCS) defines 'chronic inundation' as tidal flooding affecting 10% or more of a community's usable land at least 26 times per year. Under a moderate (intermediate) scenario, nearly 170 communities will reach this threshold by 2035, increasing to over 270 by 2060 and nearly 490 by 2100. A high scenario projects up to 670 communities affected by 2100, including over 50 populous cities such as New York City (four boroughs), Boston, and Oakland. The report highlights that socioeconomically vulnerable neighborhoods are disproportionately affected and argues that aggressive emissions reductions aligned with the Paris Agreement could spare hundreds of communities from this fate. Adaptation options include defending (seawalls, levees), accommodating (elevating homes, pumps), and managed retreat.

The Union of Concerned Scientists (UCS) identifies New York communities at risk of 'chronic inundation'—defined as high tide flooding 10% or more of usable, non-wetland area at least 26 times per year. Under a high sea level rise scenario, 14 New York communities will face this by 2100, including four New York City boroughs, with significant impacts on Manhattan (12%), Queens (15%), and Brooklyn (15%). Some areas, such as Coney Island and Long Beach, could face chronic inundation as early as 2060. The document argues that curtailing warming to approximately 1.8°C could spare between three and 13 communities by 2100. To address these risks, UCS recommends phasing out risky coastal development, enhancing disaster response frameworks like FEMA's grants, and creating new policies for managed retreat and relocation.

The 2016 assessment reveals a significant decline in elephant ivory availability in historical physical markets like New York City, San Francisco, and Los Angeles, potentially due to state-level bans. However, the market appears to be pivoting toward online platforms and states without strict regulations, such as Washington, DC and Oregon. The report documents 1,589 items in physical retail and 2,056 items across six online platforms, noting widespread confusion among vendors regarding legal exemptions and a trend of mislabeling ivory as 'bone' or 'mammoth' to evade detection.

The document synthesizes findings from systematic reviews to argue that pesticide exposure is linked to various cancers, reproductive issues, neurological disorders, and respiratory problems, particularly in vulnerable populations like children and pregnant women. It advocates for the reduction of pesticide use and the banning of cosmetic pesticides in Canada.

The author calls for a large turnout at the 2017 Peoples Climate March in Washington, D.C., to signal that Americans still care about climate change despite the political climate of the Trump administration. The text highlights the 2014 march as a catalyst for previous U.S. climate actions, such as the Clean Power Plan and the Paris agreement, and emphasizes the need for solidarity and systemic political accountability to protect the planet.

The briefing analyzes China's 'Standard for Energy Consumption of Civil Buildings' (GB/T51161-2016), which establishes energy quotas based on metered performance relative to peer groups. It argues that U.S. entities can benefit from China's approach to whole-building metered assessment, the localization of performance targets to account for market dynamics, and the challenges of aligning operational energy targets with design codes.

The document argues that promoting active travel—defined as walking, cycling, and public transit—creates a 'quadruple win' by reducing chronic disease, improving air quality, slowing climate change, and increasing health equity. It provides a framework for health professionals to encourage patients to integrate physical activity into their daily routines and to advocate for urban planning policies, such as the '5 Ds' of community design (density, land use diversity, design, destination accessibility, and distance to transit). A significant portion of the guide focuses on the Growth Plan for the Greater Golden Horseshoe in Ontario, explaining how intensification and complete community planning can facilitate a shift away from automobile dependence.

The document argues that urban water and sanitation systems in Alberta face significant risks from increasing temperatures, precipitation shifts, and extreme weather events. To build resilience, it advocates for a 'multi-barrier' approach to robustness, the integration of redundancy through source water diversity and decentralized treatment, and the promotion of resourcefulness via low-impact development (LID) and green infrastructure. Specific recommendations for Calgary and Edmonton include conducting stochastic hydrology analysis on source watersheds, reviewing regulatory obstacles to decentralized water technologies, and exploring economic instruments like stormwater levies and water trading systems.

The document argues that Alberta's cities must move beyond historical climatic patterns to build resilience against more frequent and intense extreme weather events. It emphasizes integrating climate projections into emergency planning, investing in robust and redundant infrastructure, and fostering community resourcefulness through participatory engagement.

The report argues that interoperable transit data is essential for the realization of 'mobility as a service' (MaaS), which allows users to seamlessly combine various transportation modes. It identifies significant barriers to this goal, including poor data quality, a lack of standardization for ride-hailing and car-sharing, and misaligned incentives. The authors estimate that achieving full data interoperability could boost ridership of alternative transportation by 5% to 10%, representing a market opportunity of $3 billion to $6 billion in the U.S. To address these challenges, the report proposes the formation of a cross-industry consortium to establish and maintain data standards and innovate in user-interface design and payment technology.

The study evaluates 52 climate actions from the 2014 UN Climate Summit, finding that while overall output performance after one year exceeds expectations, there are significant disparities between action areas and a persistent implementation gap in developing countries.

The document argues that sustainable public procurement is essential for deploying infrastructure that optimizes value for money (VfM) across the entire asset life cycle. It details the roles of governments, development banks, and private investors in managing environmental and social risks, and examines the legal instruments—such as UNCITRAL and EU directives—that enable the integration of sustainability into tendering. The paper also discusses the importance of Environmental Impact Assessments (EIAs) and the use of financial incentives like green bonds and accelerated depreciation to encourage green innovation.

The Clean Air Task Force (CATF) opposes New York City's proposed biodiesel heating fuel mandate, arguing that increasing demand for vegetable oil-derived biodiesel drives the expansion of palm oil production. This expansion leads to the destruction of tropical peatland forests, particularly in Indonesia and Malaysia, resulting in significant carbon dioxide releases and public health crises. CATF contends that even soybean-based biodiesel contributes to these impacts through global market fungibility and that current USEPA lifecycle analyses underestimate these greenhouse gas emissions.

The report finds that millions of Latinos in the US are disproportionately exposed to toxic air pollutants and ozone from oil and gas infrastructure, leading to significant health burdens. It highlights that 1.81 million Latinos live within a half-mile of such facilities and 1.78 million live in counties where cancer risks exceed EPA concern levels. The document argues that poverty and lack of health insurance exacerbate these risks, and calls for the EPA to regulate existing facilities, not just new ones, to protect public health and address climate change.

The Union of Concerned Scientists analysis finds a significant disparity in how automakers deploy electric vehicles (EVs) across the United States. While BMW, General Motors, Nissan, and Tesla are identified as leaders, others like Honda, Toyota, and Fiat Chrysler are labeled laggards due to limited model availability or a lack of plug-in offerings. The report highlights a stark geographic divide, noting that California's Zero Emission Vehicle policy has made it the only state where all available US EV models are offered, while consumers in other regions face severe shortages of EVs at dealerships.

The report analyzes the US electric vehicle (EV) market as of 2016, finding that while cumulative sales were nearing 500,000, progress among automakers is uneven. BMW, General Motors, Nissan, and Tesla are identified as leaders, while Honda, Toyota, and Fiat Chrysler are characterized as laggards. A significant disparity in vehicle availability exists between California and the rest of the US, largely attributed to California's Zero Emission Vehicle (ZEV) program. The authors argue that limited model availability and poor dealership inventory outside California hinder the national transition to electric transportation.

The document details how Hurricane Sandy and rising sea levels caused extensive damage to the Statue of Liberty and Ellis Island in 2012, resulting in an estimated $77 million in losses and significant economic disruption to tourism. It explains that sea levels in the New York area have risen by over 1.5 feet since the 1850s, exacerbating storm surges. In response, the National Park Service is implementing resilience measures, such as elevating electrical systems up to 20 feet, as part of a broader effort to manage climate change risks for coastal properties.

The document celebrates the signing of the Paris Agreement and calls on the business community to move from government intent to implementation by adopting science-based targets, internal carbon pricing, and risk mitigation strategies to support the goal of keeping warming well below 2°C.

Friends of the Earth International asserts that the Paris Agreement fails to deliver the scale of action required to limit global warming to 1.5°C, noting that current national pledges could lead to warming of around 3°C. The organization warns that terms like 'climate neutrality' may justify the use of dangerous geoengineering, carbon markets, and nuclear energy. To achieve climate justice, the document advocates for a just global energy transformation characterized by community-owned renewable energy, the blocking of dirty energy projects, and financial support from developed to developing nations.

The Maldives is implementing a GCF-funded project starting on Sh. Funadhoo and expanding to 48 other islands to combat water scarcity caused by altered monsoon patterns and tsunami contamination. The project focuses on rainwater collection, groundwater quality, and distribution networks to reduce reliance on expensive desalination. This initiative is part of a broader national adaptation plan including zoning and erosion control, while highlighting the gap between current GCF funding and the global climate finance mandate.
