Climate change is driving global wine production to historic lows, with sparkling wine facing specific threats to its quantity and quality. Extreme weather in France, Spain, and Italy has led to reduced yields and price increases for labels like Cava and Prosecco. Higher temperatures are accelerating ripening, which alters the balance of sugar and acid, potentially resulting in higher alcohol levels and less fizzy wines. Projections suggest that if global temperatures rise by 2°C, over half of suitable wine-growing regions could shrink, with up to 90% of traditional areas in southern Europe becoming economically unviable. Adaptation strategies, such as relocating vineyards or using protective technology, are costly and may fail to preserve the unique cultural and flavour characteristics of traditional sparkling wines.

The document introduces attribution science as a method to measure how human-caused climate change affects the likelihood, frequency, and intensity of weather events by comparing current observations with simulated 'counterfactual' worlds. It details Climate Central's specific tools, such as the Climate Shift Index (CSI) for air and sea surface temperatures and the Tropical Cyclone CSI for hurricane wind speeds. The guide distinguishes between different types of attribution—event, trend, source, and impact—and notes that while temperature-related events are highly quantifiable, other severe weather like tornadoes remains an active area of research.

The report argues that inadequate housing for First Nations, Inuit, and Métis people in Canada creates severe health burdens and climate vulnerabilities, which are exacerbated by fragmented government accountability and rigid funding models. It introduces the 'Healthy Energy Homes' concept—housing that is energy efficient, climate resilient, and supports well-being—as a way to achieve co-benefits for public health and Canada's net-zero goals. The authors recommend a shift toward long-term, flexible, and Indigenous-led investment agreements, the creation of interdepartmental coordination mechanisms, and the adoption of outcomes-based procurement to replace current 'firefighter' funding approaches.

A national survey conducted by Nanos for the Canadian Association of Physicians for the Environment in October 2025 found that 65.4% of Canadians view climate change as an important priority for the government. The report highlights strong support for methane regulation (64.5%) and a high sense of urgency (75.2%) regarding government action to reduce health risks associated with climate change, such as wildfires and heat waves. These sentiments are significantly more pronounced among 'progressive' voters and those who would consider voting for both the Liberal and NDP parties.

The study uses an integrated approach combining hydroclimatic hazard impact and supply-driven input-output models to estimate damages to Sweden's food, electricity, and water supply. Between 2005 and 2022, combined hydroclimatic hazards caused EUR 8.4 billion in economic losses across the agriculture, electricity, and insurance sectors, with floods contributing the highest share of damage.

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.

Japan and South Korea experienced extreme summer heat in 2025, with Japan recording its hottest June and July in 127 years. The Climate Shift Index (CSI) indicates that human-caused climate change made these events at least five times more likely, with several cities experiencing over a month of CSI level 5 temperatures.

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 document examines the intersection of climate change, housing quality, and health in Toronto, proposing that an equity-focused Building Emissions Performance Standards (BEPS) policy can mitigate health risks for marginalized communities. It highlights how retrofits—such as switching from gas to electric heating and stoves, improving insulation, and adding mechanical ventilation—can reduce asthma risks, protect against extreme temperature events, and lower outdoor air pollution. The brief warns against the risks of tenant displacement and 'renovictions' and recommends strong tenant protections, the creation of Community Accountability Boards, and the integration of health metrics into BEPS monitoring to ensure benefits are shared equitably.

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.

A coalition of over 50 organizations in Latin America and the Caribbean (LAC) demands urgent, health-centered climate action to protect vulnerable populations. The document highlights that the region faces severe health risks from heatwaves, air pollution, and vector-borne diseases, yet lacks sufficient national health-climate plans and dedicated financing. It calls for the alignment of Nationally Determined Contributions (NDCs) with health goals, a just transition away from fossil fuels, the implementation of the Escazú Agreement, and the inclusion of health indicators in international climate funding.

The Common Position of Latin America and the Caribbean on Climate Change and Health outlines a multisectoral framework to center health in climate governance. It identifies critical gaps, such as the fact that only 11 countries in the region have national health and climate change plans and only 11.6% of Green Climate Fund investments in the region address health. The position advocates for six pillars: protecting health from climate impacts, mitigation with health co-benefits, climate justice and equity, adaptation and health system resilience, health leadership, and financing.

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 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 Asunción Declaration, issued on May 30, 2025, outlines a regional framework for the Americas to address climate extremes such as droughts and floods. It emphasizes the integration of transdisciplinary science, indigenous knowledge, and open data exchange to improve early warning systems and protect water, food, health, and energy security. The declaration highlights the region's 69% renewable energy share while noting the vulnerability of energy sources to climate events.

The Declaration of the Parties and Associated Institutions of the IAI outlines a commitment to enhance climate resilience in the Americas through transdisciplinary science, improved early warning systems, and science diplomacy. It highlights the risks that extreme weather events, particularly droughts, pose to food security and the energy transition, noting that while 69% of energy in Latin America and the Caribbean comes from renewable sources, hydroelectric power remains vulnerable. The signatories pledge to promote open data sharing, evidence-based public policy, and the mobilization of resources to support the United Nations 'Early Warning for All' initiative by 2027.

The report details a multi-stakeholder event focused on enhancing drought resilience in the Americas. It covers the role of the UNCCD in global drought economics, WMO climate findings for Latin America and the Caribbean, the technical requirements for drought early warning systems (EWS), and case studies from the Southern Cone and the Yacyretá hydroelectric plant. The document emphasizes the need for science-policy integration, innovative financing models involving the private sector, and the use of science diplomacy to coordinate regional responses to climate-driven water scarcity.

A survey of 10,751 adults in India conducted between December 2024 and February 2025 reveals that a majority of the population has personally experienced extreme weather events, such as severe heat waves (71%) and agricultural pests (60%), within the past year. These experiences correlate with high levels of worry regarding local impacts, particularly species extinction (61%) and agricultural pests (62%). While most respondents believe global warming significantly affects these events, 32% of the population reported they had never heard of global warming.

The guide outlines the relationship between climate change and four types of summer extreme weather. It notes that heat is the deadliest weather event, killing nearly 500,000 people annually since 2000 globally, and that fossil fuel pollution drives these heat waves. It explains that oceans absorb nearly 90% of Earth's excess heat, which supercharges hurricanes by increasing intensity, rain rates, and storm surges. Regarding flooding, the guide states that a warmer atmosphere holds more moisture, leading to more frequent and intense heavy rainfall since the 1950s. Finally, it attributes the increasing threat and length of wildfire seasons to rising temperatures and erratic rainfall patterns that make vegetation more flammable.
