Climate Central's analysis of 239 major U.S. cities from 1970 to 2025 found that 95% of these cities experienced an increase in 'mosquito disease days'—days with temperatures suitable for West Nile virus transmission. On average, these cities saw an increase of 18 days per year. The largest increases occurred in the Southeast, Northeast, and Northwest regions, with San Francisco, CA, seeing the highest increase of 52 days. The report also notes that while West Nile virus is the most common mosquito-borne disease in the U.S., warming is expanding the risk and range of other viruses like dengue and Zika, particularly along the Gulf Coast and into the Ohio Valley and Upper Midwest by 2050.

The report argues that investing in climate services for health (CSfH) provides high economic returns, ranging from US$3.60 to $68.40 per dollar invested, due to the modest cost of implementation relative to the high value of lives saved. It defines CSfH through seven key activities—including early warning systems, disease surveillance, and resilient infrastructure—and estimates that a median-sized developing country requires an annual investment of US$12 to $18 million. Despite these returns, the study finds significant barriers to uptake, including a lack of integrated meteorological data in health surveillance systems and poor cross-agency collaboration between meteorological and health institutions.

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 document explains how climate change—specifically warmer winters, hotter summers, and altered precipitation—is expanding the range and survival of disease-carrying insects like mosquitoes and ticks. It highlights specific threats in the US, such as Eastern Equine Encephalitis in New England and Lyme disease in the Northwest, while noting that over 8 billion people could be at risk of malaria and dengue by the end of the 21st century if emissions continue to rise. The guide advises reporters to examine weather patterns, social determinants of health, and to consult vector biologists.

The document analyzes how climate change impacts public health in Senegal through heatwaves, floods, and droughts, while highlighting a community-led resilience project in Widou Thiéngoly.

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 outlines the severe health threats posed by climate change, including increased mortality from heatwaves, air pollution, and infectious diseases, while highlighting the 'triple win' of improving public health, creating a sustainable economy, and protecting the environment through aggressive mitigation and adaptation.

Central Africa has experienced warming between 0.75°C and 1.2°C since 1960, leading to widespread losses in health, food security, and economic growth. Future risks include lethal heat exposure, severe biodiversity loss above 2°C, and significant GDP reductions. Adaptation requires increased finance, nature-based solutions, and improved climate services, though the region faces severe data constraints and funding gaps.

The document details how East Africa has experienced warming exceeding the global average, leading to increased drought frequency, glacier loss, and significant economic losses. Future projections indicate severe risks to human health, food security, and biodiversity, particularly if warming exceeds 1.5°C. It emphasizes the need for transformative adaptation, increased climate finance, and improved climate services to build regional resilience.

The report assesses Ethiopia's development path to 2040, highlighting a tension between rapid GDP growth and lagging human development indicators. While the country has seen significant improvements in health and agricultural yields, it faces critical bottlenecks in primary education completion, basic infrastructure (WASH), and gender equality. The analysis warns that political liberalisation may create short-term instability due to ethnic factionalism and an 'anocratic' regime type. The report contrasts a positive 'Abiynomics' scenario, driven by targeted investments in human capital and governance, with a 'Dark Days' scenario characterized by political regression and economic decline.

The document details how climate change acts as a major global health threat through direct effects like extreme heat and storms, and indirect effects mediated by natural systems (air pollution, vector-borne diseases) and human systems (poverty, migration, conflict). It highlights that vulnerable populations, including children, the elderly, and those in low-income regions, are disproportionately affected.

The paper examines the intersection of health and regionalism within the Southern African Development Community (SADC). It finds that while SADC has established frameworks like the Protocol on Health (1999) and the Regional Indicative Strategic Development Plan (RISDP), the SADC Secretariat has a limited role, acting primarily as a facilitator for member states and international donors. Policy implementation is left to individual governments, often outsourced to NGOs and CBOs via donor funding. Case studies in Swaziland and Zambia reveal a lack of regional policy embeddedness at the national level. However, specific cross-border initiatives targeting HIV/AIDS, malaria (E8), and tuberculosis in mining have shown progress through dedicated funding and political commitment.

The report assesses climate variability and future projections across central, eastern, western, and southern Africa, highlighting a critical gap in observational data and a lack of consensus among climate models. It details regional risks—such as the 'east African climate change paradox' and the vulnerability of the Congo rainforest—while providing country-specific analysis for Malawi, Rwanda, Senegal, Tanzania, Uganda, and Zambia. The document emphasizes the need for improved high-resolution modelling and better communication of scientific uncertainty to support adaptation in agriculture, water, energy, and urban infrastructure.

The document argues that regional health policy in Southern Africa is 'under construction' and requires updated frameworks to address gaps in the SADC Regional Indicative Strategic Plan (RISDP). It proposes five key areas for innovation: strengthening cross-border health initiatives for HIV/AIDS and malaria, renewing the expired SADC Pharmaceutical Business Plan to combat medicine stockouts, increasing civil society engagement for public accountability, developing regional health diplomacy through South-South cooperation and diplomat training, and transitioning from disease-specific 'vertical' healthcare to 'integrated' systems that combine vertical and horizontal approaches.

The report estimates that the cost of inaction regarding climate change in Uganda's agriculture, water, energy, and infrastructure sectors will range between US$273 billion and US$437 billion from 2010 to 2050. These costs are estimated to be 24-46 times greater than the proposed adaptation budget. The study identifies water and energy as the sectors with the highest costs of inaction, while infrastructure is expected to require the most adaptation investment in the long term. Key recommendations include prioritizing the government's Costed Implementation Strategy and mainstreaming climate adaptation into national and district development plans.

The report finds that malaria cases in Tororo and Kabale are projected to more than double by 2050, driven primarily by population growth and secondarily by rising temperatures. Economic costs are expected to at least double, with Tororo's annual costs potentially rising to between US$20.1 million and US$560.5 million, and Kabale's to between US$1.55 million and US$41.7 million. While the evidence base for climate-malaria linkages in Uganda is limited, the study suggests that temperature increases will be particularly significant in the highland region of Kabale. Recommended adaptation strategies include strengthening disease surveillance, improving drainage in infrastructure projects, and continuing the distribution of long-lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS), both of which are identified as cost-effective interventions.

The report examines the intersection of climate variability and public health in Nicaragua, identifying key vulnerabilities and proposing a comprehensive risk management framework.

Kenya is highly vulnerable to climate risks, particularly droughts and floods, which create a long-term fiscal liability estimated at 2.0 to 2.4 per cent of GDP annually. The report identifies critical dependencies in the agricultural, water, and energy sectors, noting that 98 per cent of crop production is rain-fed and over half of electricity is generated by hydropower. While the government has established frameworks like Vision 2030 and the National Climate Change Response Strategy, the report finds that disaster risk management remains largely reactive and uncoordinated, with significant capacity gaps at the subnational level. It recommends deeper research into sector-specific vulnerabilities, the 'climate proofing' of infrastructure and budgets, and the integration of gender-disaggregated data into planning.

The document provides a comprehensive survey of quantitative research on the health impacts of climate change, categorizing studies by their methodological approach (primary, secondary, and comparative risk assessments) and the statistical models employed (time-series, non-parametric, and panel/spatial models). It highlights the complex relationship between climatic variables and diseases, particularly malaria, and reviews major global reports from the WHO and the Stern Review to outline the broader economic and public health implications of global warming.
