Analysis of 243 to 247 major U.S. cities reveals that 95% have seen an increase in unusually warm summer nights since 1970, with an average increase of 24 nights per summer. Using the Climate Shift Index (CSI), the report finds that human-caused climate change now strongly influences an average of 27 warm summer nights per year, compared to just one in the 1970s. The most severe impacts are concentrated in Florida and Puerto Rico, where some cities experience over two months of climate-driven warm nights annually. These trends exacerbate heat stress, disrupt sleep, and increase energy demand for air conditioning, disproportionately affecting vulnerable populations and those in urban heat islands.

Climate Central's analysis of weather data from 1970 to 2025 shows that all four Grand Slam tennis tournaments have experienced an increase in hot days (defined as $\ge$28°C). The French Open has warmed the fastest, with average temperatures rising by 3.5°C. Climate change is attributed with adding 160 extra hot days across the four events, with the U.S. Open seeing the highest absolute increase. Additionally, the frequency of heavy rain days ($\ge$10mm) has increased for the French Open, Australian Open, and Wimbledon.

Climate Central analysis indicates that climate change increases the probability of performance-impairing heat (above 28°C) for 97 out of 104 scheduled 2026 World Cup matches. Nearly half of the matches face at least a 50% chance of such heat, with the highest impact seen in the June 26 match in Guadalajara. To mitigate health and performance risks, organizers have implemented mandatory hydration breaks and increased evening matches, though only three stadiums (Atlanta, Dallas, and Houston) are fully climate-controlled.

The report finds that anthropogenic climate change has significantly increased the probability of dangerous humid heat during the 2026 FIFA World Cup compared to 1994. Using Wet Bulb Globe Temperature (WBGT) as a metric, the analysis indicates that more games are expected to exceed the 26C and 28C thresholds recommended by FIFPRO for cooling breaks and postponement, respectively. While air-conditioned stadiums may mitigate risks for players, spectators at outdoor events remain vulnerable. The study concludes that without substantial adaptation and rapid mitigation of fossil fuel use, hosting summer tournaments in the northern hemisphere will become increasingly hazardous.

The report finds that climate-driven hazards like extreme rainfall and heat stress will drive infrastructure costs to $14 billion per year by the 2050s and $19 billion by 2085 without adaptation. Proactive adaptation, requiring an average annual investment of $4.1 billion, could lower total costs by nearly $9 billion per year compared to no adaptation and over $4 billion compared to reactive adaptation. The analysis emphasizes that early action improves budget predictability and avoids cascading economic disruptions, though it notes that upgrades to existing assets must be supplemented by new protective infrastructure like dikes.

Analysis of 245 U.S. cities shows that 92% experienced rising November temperatures since 1970, with an average increase of 2.4°F. The highest warming occurred in El Paso, Texas (6.4°F), followed by Phoenix and Tucson, Arizona. This warming trend, alongside earlier springs and hotter summers, threatens cranberry production in the Northeast through frost vulnerability and 'cranberry scald', potentially increasing food prices.

The Cape Coast Metropolitan Assembly Climate Adaptation Plan (CCMA-CAP) provides a comprehensive roadmap for building resilience against climate hazards such as tidal flooding, coastal erosion, and extreme heat. Based on a vulnerability assessment, the plan prioritizes interventions across eight sectors, including water, health, agriculture, and tourism. It introduces a multi-criteria decision-making approach to rank adaptation options and proposes a diverse funding strategy involving government, international, and private sources, supported by a detailed monitoring, evaluation, and learning (MEL) framework.

The report finds that expanding the World Cup to 48 teams will significantly increase GHG emissions, with air transport emissions estimated to rise by 160% to 325% for the 2026, 2030, and 2034 tournaments. It estimates the 2026 World Cup in North America will produce at least 9.0 million tCO2e, while the FIFA-Aramco sponsorship deal could induce an additional 30 million tCO2e. Furthermore, a risk assessment of the 16 stadiums for the 2026 event reveals that half require immediate environmental intervention, with six facing extreme heat stress.

Analysis of 247 U.S. cities shows a significant increase in sweltering summer nights influenced by climate change, with average annual occurrences rising from one in the 1970s to approximately 27 currently. Nighttime temperatures have risen by an average of 3.1°F across 231 analyzed locations, with the Southwest experiencing the highest regional warming and Florida cities seeing the largest increases in climate-fueled warm nights.

The GCHA submission argues that Nepal's climate action should be explicitly linked to public health outcomes to maximize co-benefits and protect vulnerable populations. It recommends strengthening the draft NDC 3.0 by aligning conditional emissions targets with 1.5°C limits, establishing specific targets for black carbon reduction, and creating a dedicated section on air quality. The document highlights significant health risks in Nepal, including a 68% increase in heat stress exposure since the 1990s and rising transmission potential for dengue. It also emphasizes the economic burden of climate-related health issues, noting that heat exposure caused an estimated US$2.8 billion in annual potential income loss between 2014 and 2023, with the agricultural sector bearing 91.5% of that impact.

The report assesses the progress of 40 adaptation interventions across various sectors in Ethiopia, finding that nearly 67% of the 64 associated indicators lack current data for tracking. While the health sector shows strong implementation and monitoring, the water, energy, and urban sectors suffer from significant data gaps and institutional capacity constraints. The analysis highlights a critical lack of gender-sensitive indicators, with only six of 64 being gender-sensitive, and recommends expanding the NDC's scope to include the financial, labour affairs, industry, and education sectors to address heat stress and financial exclusion.

The report evaluates the health integration of NDCs from several countries, finding that while many recognize the health benefits of climate mitigation, most lack measurable health targets, dedicated funding for health adaptation, and alignment with 1.5°C pathways. It provides specific analyses for countries including Brazil, the UK, and the UAE, and offers recommendations for 'Healthy NDCs 3.0' that prioritize health as a central pillar of climate action.

The Climate Resilient Health and Well-Being for Rural Communities in southern Malawi (CHWBRC) project aims to reduce the adverse health effects of climate change—specifically malaria, cholera, malnutrition, and heat-related stress—across the districts of Ntcheu, Balaka, Machinga, Mangochi, Phalombe, and Zomba. The project employs a multi-pronged approach: establishing a climate-informed Health Early Warning and Response System (EWARS), upgrading 79 health facilities and 400 schools with solar energy and climate-resilient WASH infrastructure, and training healthcare staff and community members. It specifically targets marginalized groups, including pregnant women and children under two, to address gendered vulnerabilities and food insecurity. The project is implemented by Save the Children Australia (Accredited Entity), the Malawi Ministry of Health, and Save the Children International.

The report argues that Senegal's investment in LNG is a high-risk gamble that could lead to stranded assets and entrenched fossil fuel dependency, especially as European demand is forecast to decline. It suggests that prioritizing renewable energy is a safer and more effective path to meeting energy targets and economic growth.

This analysis quantifies the global increase in dangerously hot summer nights attributed to human-caused climate change. Using the Climate Shift Index, the report finds that billions of people are experiencing additional weeks per year of nighttime temperatures exceeding critical thresholds (18°C, 20°C, and 25°C), which impairs human health by preventing recovery from daytime heat and disrupting sleep.

The study tests the Tandem framework—a non-prescriptive guide for co-designing climate services—in Indonesia, Sweden, and Colombia. The authors found the framework effective in transforming climate information from 'useful' to 'usable' by building trust and institutional embedding. Based on these cases, the framework was enhanced to better incorporate vulnerability scoping, social equity, traditional knowledge, governance scales, and impact indicators.

The report assesses climate vulnerability in the New Juaben South Municipality (NJSM), Ghana, identifying flooding as the primary climate hazard. Using a Livelihood Vulnerability Indicator (LVI) approach, it finds that while all zonal councils are vulnerable, Srodae is the most exposed to floods and Anlo Town is the most sensitive due to poor infrastructure. Projections to 2100 indicate increasing annual rainfall and temperatures, which will likely exacerbate flash floods, droughts, and heat stress. The report highlights gender disparities, noting that women are more likely to live in flood-prone areas and have less access to social support networks and credit than men. Recommended adaptation measures include improving drainage systems, implementing early warning systems, and promoting climate-smart agriculture.

The report examines the vulnerability of agro-pastoral value chains in Kenya's arid and semi-arid lands (ASAL) to climate change, specifically focusing on temperature increases and rainfall variability. Using the VC-ARID methodology, it analyzes eight value chains: pasture/fodder, livestock, bee, gum and resin, aloe, poultry, mango, and beadwork. Findings indicate that rising temperatures and water stress generally reduce productivity for livestock, poultry, and fodder, while potentially increasing yields for gum and resin. The report emphasizes the need for transformative adaptation, including the formalization of cooperatives, improved market infrastructure, and the integration of gender-inclusive policies to enhance community resilience.

The document outlines a five-year, EUR 55.8 million project to transition Togo's health system to a climate-resilient model. It focuses on the northern regions of Centrale, Kara, and Savanes, where morbidity from malaria and diarrhoea is highest. The project aims to integrate meteorological data into health surveillance, establish early warning systems, upgrade health infrastructure to be heat-resistant, and improve community WASH services. It targets 273,224 direct beneficiaries and seeks EUR 37.6 million in GCF grants.

The document details the struggles of Pasang Norchel Tamang, a herder in Rasuwa, Nepal, whose livelihood has been severely impacted since 2015 by decreasing precipitation and rising temperatures. These climate shifts have led to the depletion of water sources, reduced pasture productivity, and livestock health issues, including miscarriages and lower fertility rates. To maintain income, the herder has increased his livestock numbers, leading to higher debt and forcing his children to drop out of school. Additionally, hydropower projects have fragmented pastures and blocked access routes, further compounding the vulnerability of the ethnically marginalized Tamang community.
