An event attribution study by World Weather Attribution found that human-induced climate change, primarily from fossil fuel combustion and deforestation, has increased the intensity of 30-day maximum rainfall in northern Pakistan by approximately 15%. The study highlights that while the event had a return period of about five years, the resulting high death toll—300 fatalities nationwide as of August 3, 2025, including 140 children—was exacerbated by rapid urbanization, informal settlements, and poor building code enforcement. The report emphasizes a significant funding gap for adaptation, noting that Pakistan requires US$152 billion for adaptation between 2023 and 2030, much of which remains unfinanced.

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.

International climate finance for Brazil grew by 84% between the 2019–2020 and 2021–2022 biennia, reaching an average of US$ 5.1 billion per year. This growth was primarily driven by the energy sector, specifically solar and wind power, and was characterized by a shift toward commercial financing instruments. While Western Europe, led by France, was the largest regional provider, the AFOLU sector—responsible for most of Brazil's GHG emissions—received only 11% of the total finance. Public institutions provided 58% of the funds, with multilateral development finance institutions (DFIs) playing a dominant role, while private finance grew fourfold to reach 42% of the total.

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.

The report details how the Trump EPA used a rare Clean Air Act provision to grant pollution exemptions to 52 facilities owned by 25 companies, including BASF, Shell, and Westlake. It highlights that these exemptions undermine the HON Rule, which aimed to reduce carcinogenic emissions by nearly 80%. The document further links these regulatory rollbacks to significant lobbying expenditures by the chemical industry and the American Chemistry Council, noting that several companies are expanding the very facilities that received exemptions.

In July 2025, the United States experienced an average temperature anomaly of 1.4°F across 196 analyzed cities, with the eastern half of the country seeing above-average temperatures. The Ohio Valley was the most unusually hot region, while the West was the only region cooler than normal. Long-term data indicates that 189 of the 196 cities have seen warming trends since 1970, with Reno, Nevada, experiencing the most significant increase. Climate change influence was particularly strong in the Southeast and in San Juan, Puerto Rico, where 19 days reached a Climate Shift Index (CSI) of 5.

The document outlines the existential risk posed by the approximately 12,000 nuclear warheads held by nine nations. It explains the physics of fission and fusion weapons and analyzes the catastrophic effects of detonations, ranging from immediate blast and radiation deaths in urban centers to global climate disruption. The guide highlights the instability of 'launch on warning' postures and the potential for 'nuclear winter' and ozone depletion, arguing that even regional conflicts would cause global famine and societal collapse.

The document presents 'Making Local Climate Action Possible', a toolkit co-designed by Climate Outreach, The Connectives, and UK local government officers. It aims to overcome barriers to business engagement—such as cost pressures and limited capacity—by providing guidance and messaging strategies based on three core principles: demonstrating purpose, empathy, and integrity.

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.

The report examines 50 years of Enhanced Geothermal Systems (EGS) development, synthesizing data from 103 projects to identify trends in drilling speed, cost, and production. It highlights a shift toward commercial viability driven by oil and gas techniques, such as horizontal drilling and multi-well pads, and notes a surge in power purchase agreements (PPAs) totaling over 610 MWe. The analysis emphasizes that while incremental and step-change innovations have improved performance, further research into superhot rock and better data transparency are needed for global scaling.

The report outlines strategies for clean energy developers to mitigate local resistance by prioritizing early, transparent, and inclusive community engagement. Using five case studies across various technologies, it emphasizes the importance of flexible siting, aligning projects with local economic goals, and establishing equitable community benefit programs. It also recommends policy reforms at the state level to streamline permitting and integrate clean energy into broader land-use planning.

The study finds that unreliable power supply in Benin forces businesses to invest in defensive measures, with extra costs accounting for 44% of total electricity expenditures. These costs, primarily driven by power generator operations, push an additional 5% of businesses into a state of 'electricity burden' (spending >10% of revenue on power). The burden is most prevalent among informal businesses, home-based enterprises, and those in the production sector.

The Climate Bonds Standard version 4.3 provides a science-based framework for certifying climate-aligned investments. It covers four primary certification paths: Use of Proceeds (UoP) debt instruments, specific assets, non-financial legal entities, and sustainability-linked debt (SLD). The standard mandates independent verification by approved verifiers and requires adherence to sector-specific criteria. For entity and SLD certifications, the framework emphasizes absolute transition pathways over relative benchmarking, requiring ambitious climate mitigation performance targets (CMPTs) and robust transition plans. Additionally, the standard includes a specialized certification for agri-food entities focusing on deforestation- and conversion-free sourcing.

ClientEarth and nine other organisations challenge the European Commission's 'Sixth Omnibus on chemicals' proposal, asserting that it introduces dangerous exceptions for carcinogenic, mutagenic, and reprotoxic substances (CMRs) in cosmetics and rolls back hazard communication rules in the CLP Regulation. The briefing contends that these changes violate the EU Charter of Fundamental Rights, fail to genuinely improve EU competitiveness, and were developed without the legally required public consultations, relying instead on industry-dominated workshops.

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.

Severe storms in the U.S. have become significantly more costly, with billion-dollar events increasing more than five-fold between 2005–2024 compared to 1985–2004. While the overall frequency of severe and tornadic thunderstorms has not changed significantly since 1979, tornado activity is concentrating into more frequent and extreme outbreaks, and 'Tornado Alley' has shifted eastward. Projections suggest a 5-20% increase in conditions favorable to severe thunderstorms per 1.8°F of warming, with one study projecting a 6.6% increase in supercell frequency by the end of the century.

Russia is attempting to form a non-Western climate coalition through BRICS, the SCO, and the EAEU to define 'sovereign' climate priorities that protect its fossil fuel exports. The document argues that Russia's approach is obstructionist, relying on the recalculation of forest carbon sinks to meet neutrality goals on paper rather than implementing genuine mitigation. While Russia pushes for shared carbon markets and 'technological neutrality' to prolong fossil fuel use, its Asian partners have largely rejected deep regulatory harmonisation. Meanwhile, Russian non-fossil fuel exporters maintain independent ESG agendas to remain competitive against foreign carbon border adjustments, despite the government's lack of a domestic carbon price.

International climate finance for Brazil averaged US$ 5.1 billion per year in 2021–2022, an 84% increase from the 2019–2020 period. This growth was primarily driven by the energy sector, particularly solar and wind power, and a significant rise in private capital from commercial financial institutions. While Western Europe was the largest regional provider, the report highlights a stark imbalance in sectoral allocation: the AFOLU sector, responsible for most of Brazil's GHG emissions, received only 11% of total finance. The majority of funds were earmarked for mitigation (80%) and delivered via commercial debt and equity, while grants and concessional finance declined by 43%.

International climate finance to Brazil averaged R$ 26.6 billion per year in 2021–2022, an 84% increase from 2019–2020. Growth was primarily driven by the energy sector, specifically solar and wind power, and a significant rise in private commercial financing. While Western Europe, led by France, was the primary source, the AFOLU sector—responsible for most of Brazil's emissions—received only 11% of total funding, mostly through public multilateral sources.
