The document examines how rising temperatures increase the speed and frequency of thunderstorm straight-line winds, particularly in the central U.S., and projects an increase in the occurrence of large-scale derecho events.

The report synthesizes 225 interviews with stakeholders to assess how climate and health policies are integrated. It finds that while these policies are currently siloed, there is a strong consensus that integration is necessary to maximize co-benefits and address complex health threats. The document identifies systemic barriers such as funding shortages and institutional silos, while proposing strategies like 'health in all policies' and the use of trusted health professionals as climate advocates.

A Spring 2025 survey of 2,164 Indian adults reveals high levels of concern and personal experience with global warming, with 90% of respondents worried and 89% reporting personal experience of its effects. While a majority believe global warming is human-caused and support a transition to renewable energy, significant knowledge gaps exist regarding specific causes, such as livestock emissions. The report also highlights severe vulnerability, with 64% of households requiring several months to recover from a severe flood and 30% having moved or considered moving due to weather-related disasters.

The document advocates for the protection of marine ecosystems and the rights of Latino communities to clean water and equitable coastal access. It highlights the disproportionate impact of climate disasters and pollution on Latinos and lists specific legislative bills to address offshore drilling, deep-sea mining, plastic pollution, and NOAA funding.

The document explains that attribution science uses climate models and observational data to compare a world with human-induced warming to a fictional world without greenhouse gas emissions to determine the impact of climate change on specific weather events. It notes that 83% of such studies find a climate link and encourages journalists to explicitly connect these events to fossil fuel use and human vulnerability.

A study by scientists from the Philippines, UK, and Netherlands found that human-induced climate change, primarily from burning fossil fuels, increased the likelihood of the potential intensity observed during the 2024 late typhoon season in the Philippines by a factor of 1.7. The analysis focused on the sequence of six storms hitting northern Luzon, including Super Typhoon Man-Yi, and found that the probability of at least three major typhoons making landfall in a single year has increased by 25% in the current 1.3°C warmed climate compared to a world without fossil fuel combustion.

The document reports that 2024 is on track to be the hottest year on record, with global temperatures exceeding 1.5°C above pre-industrial levels for the first time. In the U.S., 24 billion-dollar disasters occurred through November 2024, resulting in at least 418 deaths and $61 billion in damages, excluding the costs of Hurricanes Helene and Milton. The analysis highlights a shrinking interval between such disasters, falling to an average of 12 days in 2024 compared to 82 days in the early 1980s.

The document outlines the requirements of FERC Order No. 1920, which mandates that transmission providers develop at least three diverse Long-Term Scenarios over a 20-year horizon to plan electric transmission. It emphasizes that state participation is critical for these scenarios to accurately reflect state policies and priorities, particularly within the PJM Interconnection LLC.

The document examines the Eastern Mediterranean migration route, highlighting a shift toward deterrence policies across both EU member states (Greece, Cyprus) and neighboring countries (Egypt, Lebanon). It analyzes how EU external migration policy encourages these nations to act as 'gatekeepers' through financial and technical support in exchange for border management and the reduction of irregular departures. The report details specific mobility patterns, such as the surge in Egyptian migration via Libya and the displacement of Syrians and Lebanese due to regional conflict, while noting a systemic lack of legal migration pathways and significant barriers to healthcare, education, and employment for refugees and migrants across all four countries.

Attribution studies in Brazil indicate that fossil fuel combustion increased the likelihood and intensity of recent floods in Rio Grande do Sul and droughts in the Amazon. Despite these impacts, the Brazilian government continues to support oil and gas expansion, with plans to increase oil production by 63% and gas by 124% by 2032. Petrobras, which controls over 90% of domestic production, is estimated to be responsible for USD 500 billion in climate damages between 2018 and 2023. While Brazil has pledged to reduce emissions by up to 67% by 2035 and has successfully increased wind and solar power to reduce reliance on hydropower, its overall climate policies are rated as 'Insufficient' by Climate Action Tracker.

The document describes a 'hazard synthesis' method developed by World Weather Attribution to combine different lines of evidence into a single number representing the influence of climate change on an extreme event's intensity and likelihood. It notes that while this approach is more realistic than using models or observations in isolation, it faces limitations when events would have been impossible in a cooler world or when climate models contradict basic physics, such as the Clausius-Clapeyron relationship. The author emphasizes that human expertise and experience are necessary to evaluate these results, as automated or AI-driven analysis cannot yet account for model deficiencies or data discrepancies.

The document outlines a four-step process for utility climate risk planning: identification, quantitative assessment, mitigation, and risk distribution. It emphasizes the need for utilities to move beyond siloed resilience plans by incorporating both physical risks (e.g., extreme weather) and transition risks (e.g., carbon taxes, policy changes) into core planning documents like Integrated Resource Plans (IRPs). The authors advocate for the use of high-resolution, long-term climate datasets (30+ years) to accurately model extreme events and argue that clean energy portfolios reduce financial volatility for residential customers compared to fossil-heavy portfolios. Finally, it provides actionable recommendations for regulators to mandate risk assessments, create financial incentives for transitioning away from fossil assets, and explore self-insurance funds to protect low- and middle-income customers from catastrophic costs.

The document links the increasing frequency and intensity of heatwaves, droughts, and floods in Argentina to human-caused climate change, specifically highlighting the role of fossil fuel emissions. It notes that while Argentina has a 2050 net-zero target, the government continues to prioritize oil and gas production, particularly in the Vaca Muerta fields, and provides significantly more investment to 'dirty energy' than to renewables. The briefing also identifies a lack of transparent emissions data for individual firms and notes that lobbying by fossil fuel companies has secured production-friendly policies.

The document outlines the prevalence of climate anxiety, particularly among youth and vulnerable populations, and advises journalists to treat these feelings as reasonable responses to environmental threats rather than pathologies. It emphasizes the link between climate distress and pro-environmental action and provides a directory of resources for both reporters and the public.

The document examines the intersection of the climate crisis and the US insurance system, focusing on the aftermath of Hurricane Helene in North Carolina. It highlights a disconnect where insurers seek significant rate hikes—up to 99% in some coastal areas—despite historical profitability, while many homeowners remain uninsured for flood damage. The authors argue that the insurance industry exacerbates the climate crisis by investing over $500 billion in fossil fuel-related assets and underwriting fossil fuel projects, thereby profiting from the drivers of the extreme weather that leads to higher insurance claims.

The document explains that fall foliage is driven by day length, temperature, and rainfall, all of which are being altered by climate change. While the effects are complex and vary by species and latitude, warming fall nights and increased weather extremes like drought and wildfires are disrupting traditional leaf cycles. This has implications for both the tourism economy and the capacity of forests to sequester carbon.

The report evaluates the effectiveness of nature-based infrastructure (NBI) and hybrid infrastructure in 12,000 hectares across the Lambussie, Wa West, Lawra, and Jirapa districts of Ghana. Comparing a reference scenario of no action against NBI and hybrid interventions, the analysis finds that both NBI and hybrid options effectively mitigate floods and droughts across various Shared Socioeconomic Pathways (SSP). Specifically, reforestation of a 3,500-hectare area in one district reduced flood risk by 46.7%.

The ADAPTE project assesses how air pollution and extreme weather interact to affect human health in Mexico City, Santiago, Buenos Aires, and Bogotá. It finds that suspended particles and nitrogen oxides in these cities significantly exceed WHO standards, with respiratory and cardiovascular mortality risks varying by city, season, age, and socio-economic status.

The report finds that providing a better life for future generations remains the top motivation for U.S. voters to reduce global warming across all political groups. Since 2017, there has been a significant increase in voters citing the prevention of extreme weather and global poverty/starvation as primary motivators, while support for economic arguments (green jobs) and energy independence (foreign oil) has declined.

The briefing links the increased frequency and intensity of US extreme weather events, such as the July 2023 heatwave and August 2024 California wildfires, to climate change driven by fossil fuels. It highlights that US oil and gas production emissions rose roughly 42% between 2011 and 2022 and notes that 88 large fossil fuel and cement companies are responsible for 48% of the rise in fire-danger conditions in the region. The document argues for corporate accountability, citing a Climate Analytics estimate that the 12 most polluting companies are responsible for USD 15 trillion in economic damages from 1985 to 2018. While the US has seen significant growth in solar and wind capacity and electric vehicle sales, primary energy consumption remains dominated by petroleum (38%), natural gas (36%), and coal (9%) as of 2023.
