A May 2025 survey of 1,040 U.S. adults found that while 82% of Americans believe homeowners insurance costs are increasing, only 48% attribute this rise to global warming. In contrast, 69% link the increases to disasters such as hurricanes, floods, and wildfires. Other highly cited drivers include inflation (70%) and insurance company profits (69%). A significant political divide exists regarding the role of global warming, with 71% of liberal Democrats and only 27-28% of Republicans acknowledging its contribution.

A May 2025 survey of 1,040 U.S. adults found that while 82% believe homeowners insurance costs are increasing, only 48% attribute this rise to global warming. Other factors, including inflation (70%), corporate profits (69%), and weather-related disasters (69%), are more widely cited as contributors. A significant political divide exists: 71% of liberal Democrats and 61% of moderate/conservative Democrats link global warming to rising costs, compared to only 27% of liberal/moderate Republicans and 28% of conservative Republicans.

The 2025 fire season in Spain and Portugal saw extreme burned areas, with Spain experiencing its worst fires in 30 years and Portugal burning 260,000 ha. These events coincided with the most intense heatwave on record in Spain. Analysis indicates that a 1.3°C increase in global temperatures since preindustrial times has made these extreme fire-conducive weather conditions approximately 40 times more likely, transforming an event that would have occurred once every 500 years into one expected every 15 years.

Climate Central argues that the Department of Energy (DOE) report, “A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate,” fails to represent the scientific consensus and should not serve as a policy basis. The organization asserts that the DOE report selectively ignores two decades of scientific developments and omits major international assessments. Specifically, Climate Central contends that the DOE understates the link between human-caused climate change and the increasing intensity, rainfall, and rapid intensification of hurricanes, as well as the acceleration of sea-level rise. It further argues that the DOE's analysis of temperature extremes is misleading by focusing on the 1930s Dust Bowl era without global context and that its assessment of wildfires in the western U.S. is incomplete. Finally, the document disputes the DOE's claims regarding solar variations and the validity of extreme event attribution (EEA) methodologies, while arguing that the DOE's use of GDP to downplay disaster costs ignores the increasing physical hazards of climate change.

The Fall 2025 'Climate Change in the American Mind' report finds that 72% of Americans believe global warming is happening, with 58% attributing it primarily to human activities. While 64% of adults express worry about global warming, a significant majority (61%) underestimate the prevalence of this concern among the general public. The report highlights a high level of perceived risk, with majorities believing global warming will harm plant and animal species (69%) and future generations (68%). However, personal and social engagement remains relatively low, as 44% of respondents say they never discuss global warming with family and friends. Consumer activism is present but limited, with 31% of Americans reporting they have rewarded companies taking steps to reduce global warming through their purchases in the past year.

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.

A research paper by World Weather Attribution finding that climate change made the extreme fire weather conditions of 2025 in Türkiye, Greece, and Cyprus approximately 10 times more likely and significantly more intense.

The Canadian Climate Institute asserts that escalating climate risks threaten Canada's trade infrastructure and economic stability. The document highlights the severe economic toll of climate-driven events, citing a projected cost of $25 billion to the economy in 2025, and advocates for treating climate-resilient infrastructure as a project of national interest to safeguard long-term wealth creation.

A research analysis by World Weather Attribution finds that human-induced climate change made a July 2025 heatwave in Norway, Sweden, and Finland approximately 2°C hotter and at least ten times more likely than in a preindustrial climate. The event caused significant strain on healthcare systems, disrupted reindeer grazing and Sámi livelihoods, and led to increased drowning deaths and wildfires. The report highlights that current winter-focused building designs in the Nordic region are inadequate for rising temperatures and that similar heatwaves are now twice as likely as they were during the previous major event in 2018 due to a global warming increase from 1.1°C to 1.3°C.

The policy brief outlines how climate change and historical land management have increased wildfire risk across Canada, leading to record-breaking seasons and significant financial losses. It proposes five key government interventions: restricting development in high-hazard zones, mandating fire-resilient building codes, implementing fuel management and Indigenous cultural burning, increasing firefighting capacity, and accelerating carbon emission reductions.

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 examines how climate change is creating a home insurance crisis in the U.S., characterized by skyrocketing premiums and widespread policy non-renewals. It asserts that 'Big Oil' companies, who knew about the risks of fossil fuels as early as 1954, are responsible for these conditions. The report highlights specific state-level crises in Florida, California, and Hawaiʻi, and advocates for policy solutions—such as subrogation and legislative surcharges—to shift the financial burden from policyholders to the fossil fuel industry.

Using Google Search data, the Yale Program on Climate Change Communication identifies that interest in climate change in the United States follows predictable cycles tied to Earth Day and the school year, as well as spikes driven by extreme weather. While heatwaves trigger nationwide interest, events like wildfires produce more localized spikes based on geographic exposure, such as the 2023 Canadian wildfires affecting the American Northeast. The authors argue that these trends can be used by decision-makers to time communications on risk, adaptation, and the transition to renewable energy when public awareness is highest.

The 33rd meeting of the IAI Conference of the Parties (CoP-33) in Asunción, Paraguay, focused on strengthening regional scientific cooperation to address global environmental change. Key outcomes include the adoption of the Asunción Declaration on Water Security, Biodiversity, and Climate Resilience, the establishment of the Indigenous People Advisory Committee (IPAC), and the launch of new transdisciplinary and science diplomacy curricula. The meeting also addressed funding uncertainties for Belmont Forum Collaborative Research Actions (CRAs) and approved the appointment of the World Meteorological Organization (WMO), the American Geophysical Union (AGU), and the Venezuelan Institute for Scientific Research (IVIC) as Associates. A special session on Paraguay highlighted the increasing intensity of droughts and wildfires, emphasizing the need for improved early warning systems and the integration of science into diplomatic negotiations for water management.

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.

The study analyzed rainfall events in Colombia and Venezuela, finding that the June 2025 floods were not meteorologically extreme, with return periods of 10 and 3 years respectively. While some data suggests a slight decrease in rainfall likelihood and intensity in a cooler climate, high uncertainty remains due to model disagreement and a lack of high-quality in-situ weather data in northern South America. The report emphasizes that vulnerability is exacerbated by informal urbanization, deforestation, and socio-economic instability, necessitating increased investment in weather monitoring and climate resilience to manage both droughts and intense downpours.

Between 1980 and 2024, the U.S. experienced 403 billion-dollar disasters resulting in over $2.9 trillion in direct costs and nearly 17,000 deaths. The frequency and cost of these events have risen sharply, with the average time between disasters dropping from 82 days in the 1980s to 19 days in the last decade. Tropical cyclones are the costliest event type, while severe storms are the most frequent.

The document identifies a pattern of right-wing and fossil fuel-linked disinformation during Canadian wildfire seasons that downplays climate change and obstructs policy action. It urges Canadian policymakers to implement laws against greenwashing, define climate disinformation scientifically, and regulate the monetization and amplification of such content by tech platforms.

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.

The document highlights the increasing frequency and severity of wildfires in Canada, emphasizing that current support systems are strained. It calls for the full implementation of the National Adaptation Strategy, modernization of infrastructure, and a change in financial aid to prioritize preparation over intervention. The author notes that adaptation is critical for economic security, citing that every dollar invested in adaptation can save up to 15 dollars in avoided costs.
