The Fall 2025 report on 'Climate Change in the American Mind' reveals that 72% of Americans believe global warming is happening, with 58% attributing it primarily to human activity. While 64% express worry about global warming, a significant majority (61%) underestimate the prevalence of this concern among their fellow citizens. The report highlights a strong perception that global warming is currently affecting U.S. weather, particularly extreme heat (74%), wildfires (72%), and droughts (72%). Despite these beliefs, frequent discussion of the topic remains low, with 44% of adults stating they never discuss global warming with family and friends. Personal importance of the issue has declined to 59%, the lowest level in 10 years. Consumer activism is present but limited, with 31% rewarding climate-friendly companies and 26% punishing those opposing climate action over the past year.

The report examines how climate hazards—including sea-level rise, extreme heat, and flooding—threaten Indonesia's military infrastructure, food security, and territorial sovereignty. It highlights the strategic risks of continued coal dependence, such as public health crises and corruption, while positioning the renewable energy transition as a critical national security priority to enhance economic competitiveness and geopolitical stability.

The document analyzes how employment in outdoor sectors—such as agriculture and construction—correlates with public concern about extreme heat in the US. It finds a moderate positive correlation overall, though this varies by region: concern is higher in the South and West but lower in the Midwest and Northeast. The briefing highlights the disproportionate impact of heat on marginalized groups and the economic risks of inaction, while comparing state-level heat protections and international policy examples.

A forecast for extreme heat across the Southwest U.S. and northern Mexico indicates temperatures up to 18°F above normal, with the Climate Shift Index (CSI) attributing a level 5 likelihood to human-caused climate change. Approximately 53 million people are expected to be affected by these conditions, which are compounded by persistent drought in the region.

The briefing examines how the prevalence of outdoor work correlates with worry about extreme heat in the U.S., finding a modest positive correlation at the county level and a stronger one at the state level, though results vary significantly by region.

The analysis finds a modest positive correlation between the proportion of outdoor workers and worry about extreme heat at the county level, though this relationship varies by region. While the South and West show positive correlations, the Midwest and Northeast show negative correlations. At the state level, a stronger positive correlation exists. The document also notes a gap between heat worry and the implementation of worker protections, highlighting that some high-worry states like Texas and Florida have blocked local heat safety standards, while California's 2005 standards are linked to a 30% reduction in heat-related injuries.

A letter from Oregon's congressional delegation requesting the repeal of Executive Order 14260, which they argue illegally undermines the sovereignty of states and localities to pursue tort cases against oil and gas companies for climate deception and pollution.

An analysis of 240 UK cities from 1970 to 2024 shows that 85% have experienced an increase in the average number of days per year exceeding 27°C. In cities such as Cambridge, Luton, and Bedford, the average number of such days rose from 1 per year in the early 1970s to 11-13 per year between 2020 and 2024, with human-caused climate change responsible for the majority of this increase.

Analysis of 247 major U.S. cities shows that under high-emissions scenarios, summer high temperatures are projected to increase by an average of 3.6°F by 2060 and 7.9°F by 2100. For many cities, these future conditions will resemble current climates in locations hundreds of miles to the south, with 16 cities projected to reach temperatures only currently found in Pakistan, the Middle East, and North Africa.

A heat event in the Western U.S. from July 8-11, 2025, is forecast to bring temperatures 5-12°F above normal, with human-caused climate change making the event at least three to five times more likely for tens of millions of people.

A May 2025 survey of 1,040 American adults reveals that 69% believe global warming is happening and 60% attribute it to human causes. While 65% of respondents are at least 'somewhat worried' and many perceive risks to their local communities from extreme weather, 65% rarely or never discuss the issue with family and friends. The report also highlights a sense of personal agency, with 60% disagreeing that it is too late to act and 53% disagreeing that technology alone can solve the problem without individual life changes.

Climate Central's analysis of 65 major U.S. cities reveals that approximately 76% of the 6.2 million K-12 public school students in these areas attend school in 'extreme urban heat zones,' where the built environment adds at least 8°F of additional heat. The average student in these cities attends school in a neighborhood that is 8.3°F hotter due to the built environment, with the highest average additional heat found in New York City (9.6°F). The report highlights that children are particularly vulnerable to heat-related health risks, which can impair academic achievement and development, while noting that 41% of public school districts need to update or replace HVAC systems in at least half of their schools.

A rapid analysis by World Weather Attribution finds that climate change made a June 2025 heatwave in southeast England approximately 2-4°C more intense, increasing the likelihood of such an event from once every 50 years to once every 5 years. The report highlights that early-season heatwaves are particularly dangerous due to a lack of human acclimatisation and that the UK's building stock, designed for heat retention, exacerbates indoor overheating. While the Heatwave Plan for England provides a foundation for response, the Climate Change Committee notes that heat-related policies remain fragmented and lack long-term targets.

Climate Central analysis indicates that human-caused climate change has made the extreme heat gripping Spain and southern France in June 2025 at least five times more likely. Temperatures are forecast to reach up to 40°C, with approximately 94% of Spain's population expected to experience at least one day of exceptional climate-driven heat.

The document outlines the agricultural stresses caused by climate change, specifically focusing on the US-Mexico border region where drought, groundwater depletion, and extreme heat are threatening farming viability and worker health. It highlights the link between agricultural collapse and migration in Central America and suggests reporting angles on water cuts, pest increases, and adaptation strategies.

An attribution analysis reveals that 88% of 247 major U.S. cities have seen an increase in extremely hot summer days strongly influenced by climate change since 1970. On average, these cities now experience six such days annually, compared to zero in the 1970s, with the most significant increases occurring in the South, particularly in Texas and Louisiana.

The Center for Climate and Security (CCS) urges US lawmakers to challenge Secretary of Commerce Lutnick on proposed FY 2026 budget cuts to NOAA. The briefing highlights risks to weather forecasting, climate monitoring, and public safety, noting that funding lapses have already disabled four regional climate centers and that 27,000 years of staff experience have been lost. CCS specifically questions the decommissioning of 14 data services, the status of the Atlas 15 precipitation project, and the lack of funding for extreme heat monitoring, arguing that these cuts undermine the $7 billion private weather services market and US national security.

The report examines the vulnerabilities of the US power grid to climate change, highlighting how extreme heat, wildfires, winter storms, and hurricanes cause widespread outages. It argues that current planning focuses on reliability under typical conditions rather than resilience to high-impact, low-frequency events. The authors emphasize that structural inequities, such as the legacy of redlining, leave low-income communities and people of color disproportionately vulnerable to the life-threatening consequences of power loss. The document recommends that regional transmission organizations (RTOs) and independent system operators (ISOs) adopt forward-looking climate risk assessments, integrate energy justice principles, and reform economic metrics like the Value of Lost Load (VOLL) to prioritize human vulnerability over economic activity.

The report finds that human-caused climate change significantly increased the frequency and intensity of extreme heat globally from May 2024 to May 2025. Approximately 4 billion people experienced at least 30 additional days of extreme heat, and 195 countries saw the number of such days at least double compared to a world without climate change. All 67 significant heat events analyzed were influenced by climate change, with some becoming dozens of times more likely. The authors emphasize that while adaptation strategies like City Heat Action Plans are vital, comprehensive mitigation through the phasing out of fossil fuels is the only way to limit future harms.

The document details South Carolina's high susceptibility to sea level rise, hurricanes, and droughts, noting that 101 weather disasters with losses over $1 billion occurred between 1980 and April 2025. It highlights the critical role of federal support from NOAA, FEMA, and USDA in maintaining coastal resilience, providing disaster aid, and supporting military installations. The briefing warns that proposed FY 2026 budget cuts—including the elimination of the Sea Grant program and significant reductions in coastal research and FEMA funding—would severely hinder the state's ability to manage climate risks and protect its economy and national security infrastructure.
