The report compares a pathway aligned with U.S. climate commitments against the energy and climate provisions of Project 2025. It finds that Continued Climate Leadership would lead to significant emissions reductions, job growth, and public health improvements, while Project 2025 would increase emissions, reduce GDP, and cause additional premature deaths.

The analysis finds that human-caused climate change has significantly increased the frequency of dangerous nighttime temperatures globally, affecting billions of people. Using the Climate Shift Index, the report quantifies additional nights above 18°C, 20°C, and 25°C, noting that these temperatures disrupt sleep and increase risks of cardiovascular conditions and mortality. The most severe impacts are observed in tropical regions and urban areas due to heat island effects, with specific cities in India, Indonesia, and Africa experiencing an additional month or more of extreme nighttime heat.

GreenLatinos supports the Great Gila Bend National Monument Establishment Act, arguing that the conservation of the Great Gila Bend region is essential for public health and the protection of threatened biodiversity, particularly for marginalized communities in Arizona who lack access to nature.

Climate Central analysis shows that 88% of 242 analyzed U.S. cities have seen an increase in extremely hot days since 1970, posing significant risks of heat-related illness and death for student athletes, particularly youth and teens.

The author critiques the US Supreme Court's 5-4 decision to temporarily block the EPA's Good Neighbor Rule, which aimed to limit nitrogen oxide emissions from power plants and industrial sources in 23 states. The commentary argues that the Court disregarded significant public health benefits—including the prevention of 1,300 premature deaths in 2026 alone—and bypassed the standard judicial process by acting as a 'court of first view' rather than review. The author contends that the Court is inappropriately assuming a regulatory role ('Super-EPA') by making rushed assessments of highly technical environmental records without full briefing from lower courts.

The document assesses the integration of gender perspectives within Senegal's National Adaptation Plan (NAP) process. It finds that while some sectors, such as fisheries and aquaculture, have successfully integrated gender, others—including health and transport—show weak or nonexistent consideration. The analysis highlights systemic gender inequalities in Senegal, such as unequal land access and limited female participation in strategic decision-making, which exacerbate vulnerability to climate change. It recommends strengthening institutional collaborations, improving gender-disaggregated data, and ensuring more equitable access to climate finance to create a more inclusive adaptation framework.

Climate change is increasing the frequency of nighttime temperatures exceeding 18°C, 20°C, and 25°C, which impairs human sleep and increases health risks. Between 2018 and 2023, the average person globally experienced 4.8 additional days per year above 20°C and 11.5 additional days above 25°C due to climate change. The report highlights severe impacts in specific regions, such as California in the U.S. and West Bengal and Assam in India, where the number of added hot nights is highest.

The guide advises journalists to explicitly link extreme heat events to climate change and the burning of oil, gas, and coal, noting that heat is the deadliest extreme weather event. It provides sample language for reporting, recommends avoiding trivializing visuals, and suggests using tools like the Climate Shift Index for attribution.

From June 18-20, 2024, a major to extreme heat event is forecast for the eastern half of the U.S., affecting over 25 million people. The event is characterized by record-level high temperatures in major cities and elevated nighttime temperatures. Climate Central's Climate Shift Index (CSI) indicates that human-caused climate change has made this heat at least four times more likely in several states, including West Virginia, Ohio, and Indiana.

The Southwest United States experienced an extreme heat event from June 6 to June 13, 2024, with human-caused climate change making high temperatures at least five times more likely. The event caused record-setting temperatures in cities like Phoenix and Las Vegas, led to numerous hospitalizations for heat exhaustion, and contributed to wildfires in California.

From June 11-13, 2024, over 290 million people in Northern Africa, the Mediterranean, and the Middle East are forecast to experience extreme heat made at least five times more likely due to human-caused climate change. Maximum temperatures of 40°C or higher are expected in several countries, including Saudi Arabia, Iraq, Syria, and Egypt. The document highlights risks including wildfires in Greece, damage to Bulgaria's rose oil production, and increased vulnerability for refugees in Libya, Tunisia, and Algeria.

Wisconsin taxpayers will need to spend at least $16.7 billion through 2040 to protect communities from climate change, with municipal governments bearing the vast majority of these costs ($14.1 billion). The most significant expenses include improving stormwater management ($6.67 billion) and proactive road maintenance ($5.09 billion). The report highlights that these costs fall disproportionately on high racial minority areas and low-education rural communities, potentially consuming a significant portion of local public works budgets. It argues that fossil fuel companies should be held legally accountable for these damages.

The report finds that human-induced climate change significantly increased the frequency, intensity, and duration of extreme heat globally from May 2023 to May 2024. Using the Climate Shift Index (CSI), the study determined that 6.3 billion people experienced at least 31 days of extreme heat made at least twice as likely by climate change. It identifies 76 extreme heat waves across 90 countries and highlights critical gaps in impact reporting, particularly in developing regions. The authors advocate for City Heat Action Plans and systemic adaptations to prevent heat-related fatalities.

Analysis of 241 U.S. locations from 1970 to 2023 shows that 95% have experienced warming average summer temperatures, with an average increase of 2.5°F. The Northwest, Southwest, and South regions saw the most significant heating. Additionally, 58% of analyzed locations now experience at least 14 more above-normal summer days than in 1970. The document also highlights the health risks of extreme heat, particularly for vulnerable populations and those affected by urban heat islands, and provides a directory of monitoring tools and hurricane season resources.

The document describes a research protocol for a scoping review focused on the application of data science to mitigate the health impacts of climate change and air pollution in Africa. It highlights that environmental hazards are currently the most prominent threats to health in the region and that advanced data science skills—specifically in sourcing, managing, and modelling health and climate data—are essential but rare. The review will employ a methodology involving searches across databases such as Web of Science, Scopus, CAB Abstracts, MEDLINE, and EMBASE to examine the links between climate change, air pollution, and health outcomes.

The Canadian Association of Physicians for the Environment (CAPE) and other health professionals are calling on the government of New Brunswick to ban hydraulic fracturing (fracking) due to significant risks to human health. Citing a range of scientific studies, the authors link fracking to adverse birth outcomes, increased mortality, and higher rates of cancer and respiratory diseases. They also warn that LNG infrastructure releases dangerous pollutants and contributes to climate change, which they identify as the leading global threat to human health.

A World Weather Attribution analysis concludes that the extreme heatwave affecting the Sahel in early 2024, which coincided with Ramadan and power cuts, would have been impossible without the 1.2°C of global warming caused by human activities. The event was particularly severe in Mali and Burkina Faso, where 5-day maximum temperatures had a return time of 200 years. The study finds that human-induced warming increased 5-day maximum temperatures by 1.5°C in Mali/Burkina Faso and 1.4°C across the wider Sahel, while the current El Niño event contributed only a small amount (approximately 0.2°C). In Bamako, Mali, the Gabriel Touré hospital reported 102 deaths between 1-4 April, significantly exceeding the 130 deaths recorded for the entire month of April 2023.

The report estimates that governments in Los Angeles County will need to spend at least $12.5 billion through 2040 to adapt to climate change, with municipal governments bearing the largest share. The highest costs are associated with stormwater management to mitigate flooding ($4.3 billion) and combating urban heat islands through cool pavements ($2.5 billion) and tree planting ($1.4 billion). The study highlights that these costs disproportionately affect low-income communities and communities of color, and argues that fossil fuel companies should be held legally accountable for these expenses.

The document examines human capital as a component of comprehensive wealth in Ethiopia, Indonesia, and Trinidad and Tobago. It finds that while Indonesia and Ethiopia saw significant growth between 1995 and 2020, this progress stalled recently. Trinidad and Tobago experienced a severe decline after 2008, erasing previous gains. The authors argue that diversifying human capital away from dominant sectors—such as agriculture in Ethiopia and services in Indonesia—and investing in health, education, and data capacity are essential for long-term prosperity.

The communication strategy for Côte d'Ivoire's National Adaptation Plan (2023–2030) aims to build a climate-resilient society by informing and sensitizing diverse stakeholders. It identifies four strategic axes: political appropriation, public awareness of adaptation practices, documentation of lessons learned, and coordination. The strategy targets institutional actors, community leaders, civil society, the private sector, and the media, utilizing a mix of institutional, behavioral change, and digital communication. Implementation is estimated to cost approximately 50 billion CFA francs.
