Between 2000 and 2021, the U.S. experienced 1,542 major weather-related power outages, with 83% of all reported major outages attributed to weather. The average annual number of these events increased by approximately 78% in the 2011-2021 decade compared to 2000-2010. Severe weather, winter weather, and tropical cyclones were the primary drivers, with the Southeast, Midwest, and Northeast regions most affected. To address these vulnerabilities, the document suggests solutions such as microgrids, smart grid technologies, grid hardening, and bidirectional charging for electric vehicles.

CILRIF is a novel financial instrument developed by the UNCDF and partners to address the lack of affordable, long-term climate insurance and resilient infrastructure funding for cities in emerging markets. It operates through two linked facilities: an insurance facility providing 10-15 year coverage with premiums that decrease as cities meet resilience milestones, and a financing facility providing below-market rate loans for adaptation projects. The instrument uses a hybrid parametric and indemnity insurance model to provide immediate post-disaster liquidity while rewarding risk reduction. A financial model for 40 cities suggests that resilience interventions, such as drainage systems for flood risk or cooling networks for heat risk, can reduce annual premiums by 5% to 10% per intervention. The pilot phase targets Makati, Durban, and Freetown, with a goal of mobilizing USD 1 billion in commercial and concessional investment.

Since 1970, fall temperatures in the contiguous U.S. have increased by an average of 2.7 °F, with warming observed in 97% of 245 analyzed cities. The most significant warming occurred in Nevada, Texas, and Arizona, with Reno, Nevada, recording the highest increase at 7.7 °F. This trend has led to a higher frequency of above-normal fall days, affecting 74% of analyzed cities. These temperature shifts extend health risks from extreme heat, prolong pollen and wildfire seasons, allow disease-carrying insects to persist longer, and disrupt ecological events such as bird migrations and fruit ripening.

Analysis of FEMA heat data and Yale Climate Opinion Maps reveals a positive correlation (r = 0.12) between extreme heat exposure and worry about global warming in the U.S. However, a specific group of 217 counties—primarily in the Midwest and South—exhibit high exposure but lower-than-average worry. These counties, representing 6.4 million people, are characterized by higher proportions of white residents, rural populations, and 2020 Republican voters compared to the national average. The authors argue that these gaps in risk perception increase vulnerability to heat-related illness and death, necessitating tailored educational outreach and policy responses.

Climate Central analysis reveals that 83% of 241 analyzed U.S. cities saw an increase in summer stagnant days between 1973 and 2021, with a strong positive correlation between these events and rising summer high temperatures. Annual stagnation has also increased in 81% of these cities, with hotspots in Southern Texas and coastal California. These trends are expected to worsen with climate change, potentially adding up to 40 more stagnant days per year by late-century, which traps pollutants and disproportionately affects communities of color due to historical housing policies.

Since 1970, average summer nights in the contiguous U.S. have warmed by 2.5°F, with nighttime temperatures warming nearly twice as fast as daytime temperatures since 1895. Using the Climate Shift Index (CSI), Climate Central finds that climate change makes warm summer nights significantly more likely than warm days, posing health risks and increasing cooling costs.

The report finds that while a majority of Americans (72%) believe global warming is happening and 56% attribute it to human causes, there is a significant gap in understanding the strength of the scientific consensus. Public concern is high, with 64% feeling worried and many reporting personal experiences with climate impacts, yet social discussion of the topic remains low, with 67% rarely or never discussing it with family and friends.

A Climate Central analysis projects that by 2100, the average summer warming across 247 U.S. cities will be 8 °F, with many cities experiencing conditions currently found 437 miles to their south. For 16 cities, future summer temperatures will have no equivalent on the North American continent, instead mirroring conditions in Egypt and the Middle East. Specific projections for major cities include New York warming by 7.6 °F (similar to present-day Columbia, S.C.) and Chicago warming by 9.1 °F (similar to Montgomery, Ala.).

The Canadian Association of Physicians for the Environment (CAPE) submitted recommendations for Canada's National Adaptation Strategy (NAS) in July 2022. The submission argues that the NAS must explicitly address the intersection of climate change and both physical and mental health, noting that physicians are already observing increased asthma and anxiety linked to wildfires and extreme heat. CAPE highlights that extreme heat disproportionately affects vulnerable populations, including those in poverty, racialized communities, and older individuals. The organization calls for the NAS to include specific outcomes and targets, protect nature for its own sake, and prioritize natural infrastructure—such as urban tree canopies—to mitigate heat and improve public health. Additionally, CAPE emphasizes the need to harden health infrastructure to ensure hospitals remain functional and serve as community safe havens during extreme weather events.

Analysis of 246 U.S. locations shows that 74% have experienced an annual increase in extremely hot days since 1970, with Austin, TX seeing the largest increase. The document highlights that extreme heat risks are higher in traditionally cooler regions due to lack of acclimatization and infrastructure, and that vulnerable populations including children, seniors, and low-income households are disproportionately affected.

The Fair Cooling Fund provided USD 600,000 in grants to seven organizations to develop sustainable cold chain and cool home solutions. These investments unlocked an additional USD 1.37 million and supported projects in India, Ghana, Colombia, Egypt, and Rwanda, focusing on increasing incomes for smallholder farmers and reducing indoor and outdoor temperatures for low-income urban residents.

The Environmental and Energy Study Institute (EESI) hosted a briefing series titled 'Living with Climate Change' to address community preparation for polar vortices, sea level rise, wildfires, and extreme heat. A specific focus was placed on the polar vortex, noting that climate change is expected to affect the frequency and severity of these events. The document highlights the necessity of adaptation strategies for the energy grid and home energy efficiency to prevent deadly power losses, citing 246 deaths during the 2021 Texas polar vortex freeze.

A survey of 1,018 American adults in April 2022 reveals that while 72% believe global warming is happening and 56% attribute it to human causes, there is a significant gap in understanding the strength of scientific consensus. A majority of respondents (64%) are worried about global warming, and many perceive it as already affecting U.S. weather and local environmental risks, such as electricity power outages and water pollution. However, social engagement remains low, with 67% rarely or never discussing the topic with family and friends.

The report examines the security implications of climate change in the South and East China Seas, focusing on the interplay between regional political cohesion and food prices. It presents four scenarios—ranging from high cooperation and low prices to high fragmentation and food insecurity—to illustrate potential risks, including social unrest, the failure of governance, and increased Chinese maritime aggression. The analysis emphasizes that climate change acts as a threat multiplier, exacerbating existing geopolitical tensions and socio-economic inequalities in Southeast and East Asia.

The report argues that forests are vital to human health through three primary functions: provisioning (food, water, medicinal plants), prevention (reducing zoonotic spillover and buffering natural hazards), and healing (reducing risks of noncommunicable diseases). It highlights how deforestation and degradation trigger negative health cascades, such as increased disease spillover and higher exposure to pollution and extreme heat. The document advocates for a systems approach to forest conservation, integrating public health and environmental sectors to protect intact forests, improve working land management, diversify restoration, and create urban forests.

The report evaluates the Biden Administration's efforts to prioritize climate security across four pillars: leadership, risk assessment, international partnerships, and resilience/prevention. While it notes significant progress in high-level leadership and the publication of risk analyses, it argues that the U.S. must move from planning to execution, specifically by increasing funding for resilient infrastructure, improving climate forecasting, and mainstreaming climate security within the State Department and military engagements.

The Republic of Nauru is seeking USD 1,304,546.00 from the Green Climate Fund to implement Phase One of its National Adaptation Planning. This 18-month project focuses on strengthening governance, updating climate projections, and developing a robust evidence base to inform the updated Republic of Nauru Climate Change Adaptation and Disaster Risk Management Framework (RONAdapt). Key activities include establishing a Climate Change Adaptation Technical Working Group, conducting private sector risk assessments, and creating a centralised climate information database. The project addresses critical vulnerabilities including sea-level rise, extreme heat, and the legacy of phosphate mining, which acts as a 'threat multiplier' for climate risks.

The document details the disproportionate impact of climate change on Central Africa, highlighting significant temperature increases, biodiversity loss, and economic decline. It emphasizes the critical need for transformative adaptation and increased climate finance to mitigate future risks to health, food security, and infrastructure.

CILRIF is a financial innovation designed to provide cities with long-term climate insurance and access to capital for resilience building. The mechanism uses a results-based pricing structure where insurance premiums decrease as cities implement adaptation measures, thereby reducing overall financing costs and managing climate risk. The initiative targets specific cities in South Africa, the Philippines, and Sierra Leone, focusing on risks such as riverine floods and extreme heat.

The COP27 Resilience Hub served as a physical and virtual space to accelerate ambition and investment in climate resilience, representing over 1,500 non-state actors. The report identifies five cross-cutting messages, emphasizing that scaling adaptation is a prerequisite for containing Loss and Damage and that locally-led adaptation (LLA) requires radical collaboration. The document details thematic analysis across nine areas—including finance, food, water, and health—and highlights the role of Regional Resilience Hubs in amplifying under-represented voices from Africa, South Asia, Asia Pacific, and Latin America and the Caribbean.
