The report details how the climate crisis is accelerating in Arizona, leading to increased drought, extreme heat, and flooding. It quantifies specific impacts—such as a 71% decline in Lake Mead's volume since 2000 and nearly 500 heat-related deaths in Maricopa County during the summer of 2023—and outlines the extensive infrastructure, public health, and water management costs required for adaptation.

The document explores the 'anti-green backlash' and the practical dilemmas of the energy transition, focusing on social inequality, territorial disputes over renewables and mining, and the geopolitical implications of critical raw material sourcing. It argues that a just transition requires rebuilding the welfare state, increasing democratic participation, and addressing historical ecological debts to avoid 'eco-apartheid' and political polarisation.

The document highlights how global climate decisions at COP27 affect local areas through three primary tools: an analysis of U.S. warming scenarios, the Global Climate Shift Index (CSI-Global) tracking daily temperature influences in over 1,000 cities, and the Picturing Our Future tool visualizing sea level rise. It emphasizes the gap between current emissions trajectories and the 1.5°C to 2°C warming limits agreed upon in 2015.

The document defines Nature-based Solutions (NbS) as actions to protect, manage, and restore ecosystems to address societal challenges while providing biodiversity and human well-being benefits. It identifies a lack of specific NbS frameworks in South Asia but notes that existing national laws and policies in India, Bangladesh, and Nepal provide a foundation for their mainstreaming. The report categorizes NbS into five IUCN-based approaches: ecosystem restoration, issue-specific ecosystem-related, infrastructure-related, ecosystem-based management, and ecosystem-protection. It details 15 urban case studies, including the Yamuna Biodiversity Park in New Delhi, the restoration of riverine areas in Rohingya camps in Cox's Bazar, and the Green Lumbini Initiative in Nepal, highlighting the role of multidisciplinary partnerships and community engagement in achieving ecological and socio-economic resilience.

The report argues that India's buildings sector must adopt an integrative whole-system approach to address both embodied and operational emissions. It highlights that building operations account for about a third of India's energy use, and without intervention, energy consumption could triple by 2050. The proposed framework prioritises reducing energy needs through passive design, serving those needs with super-efficient equipment, and transitioning to clean energy procurement and demand flexibility. Key recommendations include government mandates for net-zero public buildings, the adoption of carbon accounting for corporations, and the implementation of building performance standards to ensure actual operational efficiency.

The report projects that under current trends, 1.22 billion people will be at high risk of lacking cooling access by 2030. While achieving universal electricity access (SDG 7.1.1) alone provides limited relief, combining it with the eradication of extreme poverty (SDG 1.1) could reduce the high-risk population by 36 percent to 783.3 million. The analysis highlights that urban poor populations are growing due to urbanization and the urban heat island effect, while rural poor populations in Africa remain particularly vulnerable. The report emphasizes that income and energy access are critical prerequisites for the adoption of sustainable cooling solutions.

The health community has developed policy recommendations for COP27 to address the insufficient integration of health issues into UNFCCC policy and monitoring. The document argues that climate-sensitive health threats cause millions of avoidable deaths and productivity losses, while mitigation efforts in energy, transport, and agriculture provide significant health co-benefits. It highlights that the health sector contributes 4-5% of global emissions and is a priority for adaptation in many Nationally Determined Contributions (NDCs). The text calls for urgent international financing to address health-related loss and damage and to build 'health resilience' as a foundation for economic productivity and overall climate resilience.

The briefing examines the impact of extreme heat and the urban heat island effect in Delhi, highlighting that the city is ranked as the second most heat-stressed city globally. It proposes that while Delhi has significant green space, including 18,000 parks and the Central Ridge, much of it is underutilized or dominated by invasive species like Prosopis juliflora. The author advocates for a transition from emergency heatwave planning to long-term nature-based solutions, specifically through the planting of locally adapted native species tailored to specific micro-habitats. The document provides five recommended practices for maximizing ecosystem health, emphasizing the need for a scientific species selection framework and the prioritization of greening in low-income, high-density neighborhoods to address heat equity.

The document is a supplemental petition by Earthjustice and the New York City Community Garden Coalition (NYCCGC) requesting that New York City agencies designate community gardens as Critical Environmental Areas (CEAs). It argues that these gardens provide essential services in underserved areas, including food security, flood resiliency, and mitigation of extreme heat. The petition highlights ten specific gardens as examples of these benefits and requests a city-wide assessment of all community gardens on City-owned land to ensure their legal protection against development projects.

The analysis finds that human-caused climate change made the July 2022 UK heatwave, which saw record temperatures of 40.3°C, at least 10 times more likely. Observational data suggests such a heatwave would have been approximately 4°C cooler in preindustrial times, while model-based estimates suggest a 2°C difference in a 1.2°C cooler world. The event was extreme even in the current climate, with some 1-day maximum temperatures having return periods of 1 in 1000 to 1500 years.

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.

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 analysis examines how the expansion of built-up areas at the expense of natural heat sinks like green spaces and water bodies increases urban heat risks in major cities across the Critical 9 countries. Using Copernicus Land Monitoring Service data and the IPCC's SSP1-1.9 scenario, the report details specific land-use losses in cities such as Shanghai, Karachi, and Dhaka, linking these changes to increased vulnerability to dangerous heat days (above 35°C) and rising energy demands for active cooling.

The document examines how hybrid clean energy systems—specifically pairing solar generation with geothermal district heating and cooling—can address systemic energy injustices. It highlights that low-income communities and communities of color face higher risks from extreme heat and aging gas infrastructure, such as leaks in Massachusetts. The author advocates for a holistic approach, citing a Massachusetts pilot project that repurposes gas rights-of-way for geothermal networks and research from Croatia showing the efficiency of solar-geothermal hybrids. Such systems can reduce energy costs, eliminate methane emissions, and improve security through microgrid capabilities, provided that new market frameworks and data-processing technologies are implemented to manage the complexity of distributed energy systems.

The document analyzes the trajectory of sustainable urban development, noting that while urban populations are projected to reach 68% by 2050, cities contribute significantly to global carbon emissions and biodiversity loss. It highlights a divide between the Global North's focus on infrastructure transformation and the Global South's need to 'jump start' sustainable development. The paper identifies key trends such as nature-based solutions, multimodal transportation, and a growing emphasis on equity and inclusive planning to address environmental racism and green gentrification.

The SAVi assessment finds that tree planting in Addis Ababa generates significant societal value by sequestering carbon and avoiding costs associated with air pollution, flooding, and heat. The analysis indicates that trees provide better value for money and more job creation than grey infrastructure alternatives, such as electric vehicles or rainwater harvesting tanks, provided that the nature-based infrastructure is maintained to ensure tree survival.

The document proposes 'community solar+', a strategic approach to community solar deployment designed to move beyond simple energy access to maximize local value streams. It argues that by planning deliberately, stakeholders can align solar projects with broader goals such as EV charging investment, energy resilience for vulnerable populations, and the mitigation of urban heat island effects.

The Basque Centre for Climate Change (BC3) has developed a guide containing 10 educational activities for high school students, aligned with BC3's research lines. The activities use active methodologies to cover topics such as carbon footprints, planetary boundaries, climate justice, and urban heat islands. The guide includes a conceptual overview of climate change, emphasizing the need to limit global warming to 1.5ºC, and provides structured lesson plans with specific goals, competencies, and resources.

The catalog consists of 10 independent educational activities linked to five BC3 research lines: Climate Basis, Low Carbon, Terrestrial Ecosystems, Adaptation Laboratory, and Integrated Models of Human and Natural Systems. These activities employ active methodologies, such as cooperative learning and research-based learning, to develop students' scientific and social competencies. Key topics include carbon footprint calculation, planetary boundaries, climate justice, degrowth, and urban heat islands. The guide also provides a conceptual overview of climate change, citing IPCC AR6 data to emphasize the need to limit global warming to 1.5 ºC by reducing global emissions by 43% and methane emissions by 34% by 2030.

North Africa is experiencing warming at twice the global rate, leading to increased heat waves, marine heat waves, and widespread losses in agriculture and health. Future projections indicate severe risks to food security, biodiversity, and coastal infrastructure, particularly in Egypt. Adaptation requires transformative, ecosystem-based approaches and a significant increase in disbursed climate finance.
