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.

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.

The document asserts that global hunger is caused by a profit-driven system rather than food scarcity, highlighting the role of the 'ABCD firms' and financial speculators in driving up prices. It links food systems to 34% of global greenhouse gas emissions and notes the severe impact of climate-driven droughts in Southern Africa. While acknowledging previous G20 efforts, it criticizes the lack of systemic reforms, such as regulating food speculation or implementing buffer stocks. Under its G20 presidency, South Africa has established a Food Security Task Force to study commodity price volatility and stabilization techniques.

The document advocates for Universal Social Protection Floors (SPF) as a means to ensure basic healthcare and income security globally. It highlights South Africa's role during its G20 Presidency to promote a voluntary framework for SPFs and the integration of social protection with industrial strategies. The text emphasizes the need for political will and funding, noting that only 12% of global development targets are currently on track.

The document analyzes the institutional strain on BRICS caused by its expansion, noting that while the bloc's global influence has grown, its consensus-based governance struggles with divergent member interests. It evaluates Brazil's 2025 presidency, which attempted to prioritize institutional development but saw most structural reforms deferred in the Rio Declaration. The authors contrast the informal nature of the broader bloc with the formal success of the New Development Bank (NDB) and propose six targeted, low-bureaucracy improvements—including a shared document repository and standardized onboarding—to improve operational effectiveness without sacrificing the group's flexible identity.

WEAP is a comprehensive software tool for integrated water resources planning used by over 50,000 users in nearly 200 countries. It functions as a database, forecasting tool, and policy analysis system that balances water demand—including use patterns and allocation—with supply factors like streamflow and groundwater. The software features a GIS-based graphical interface and supports scenario-based analysis to evaluate the impacts of climate change, demographic shifts, and policy changes on water systems. It has been applied in diverse global contexts, including projects in China, Rwanda, Colombia, India, Nepal, and California, to support stakeholder dialogue and evaluate environmental flows.

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 report highlights that Indigenous Peoples achieved expanded engagement and increased recognition of their contributions to sustainability in 2024 across the Rio Conventions. However, it identifies inconsistent acceptance of human rights language and a lack of direct funding for participation and customary practices as primary remaining barriers.

The document argues that while the core vision of the 1998 White Paper on Local Government remains relevant, the operational assumptions—particularly regarding funding and administration—are outdated. PARI identifies a cycle of decline driven by financial stress, patronage-based appointments, and infrastructure decay. It proposes a differentiated local government design where powers and functions are allocated based on a municipality's capacity and location in the space-economy. Key recommendations include reforming the political-administrative interface to reduce patronage, establishing clear affordability standards for basic services, and integrating climate-appropriate infrastructure requirements into the updated policy framework.

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.

The research paper examines whether South Africa has eclipsed Nigeria as Africa's dominant power. While Nigeria maintains significant demographic and resource-based weight, the author argues that South Africa has leveraged multilateral institutions, a diverse economy, and a value-driven foreign policy to achieve greater global visibility and influence. The analysis highlights Nigeria's internal security challenges and strategic drift as factors that have diminished its international standing, while noting that South Africa faces its own domestic vulnerabilities, including energy crises and high unemployment.

The ICJ issued a unanimous advisory opinion establishing that States have binding international legal obligations to prevent climate harm, including a duty to phase out fossil fuels and provide reparations for damages. The ruling affirms the right to a healthy environment as a binding norm and clarifies that sea level rise does not terminate a State's legal statehood or maritime borders.

The document highlights the critical nature of the INC-5.2 negotiations in Geneva, emphasizing the need for a treaty that includes plastic production caps, addresses toxic chemicals, and establishes robust financial mechanisms. It warns against the influence of fossil fuel lobbyists, the risks of consensus-based decision-making that could lead to gridlock, and the danger of postponing key decisions to future Conferences of the Parties (COPs).

The Trump administration has initiated the process to reopen the Powder River Basin in Wyoming and Eastern Montana for new coal leasing, reversing a 2024 Interior Department decision that halted leasing due to declining demand and the climate crisis. Earthjustice contends that this move, alongside a budget bill slashing coal royalty rates and mandating permit approvals, prioritizes corporate profits over public health and climate goals. The briefing notes that wind and solar power surpassed coal in the U.S. in 2024 and warns that coal mining continues to threaten the air, water, and health of frontline communities, including the Northern Cheyenne Tribe.

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.

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 report finds that China's consumer goods trade-in programme could accelerate the annual efficiency improvement rate of its room air conditioner (RAC) stock by up to 70% in 2025. This shift could reduce residential cooling electricity use by 3.4% to 4.1% during the summer of 2025, potentially saving consumers up to $943 million USD on electricity bills. The programme, part of the "Two New" policy, provides subsidies of 15% for Grade 2 and 20% for Grade 1 energy efficiency models, effectively steering consumers toward the most efficient units. This initiative aligns China's economic goal of boosting domestic consumption with its energy transition and decarbonisation targets.

The document outlines how climate change acts as a 'threat multiplier' for water scarcity, noting that nearly two-thirds of the global population faces severe water shortages at least one month per year. It highlights that freshwater demand is projected to exceed supply by 40% by 2030, exacerbated by agricultural use and outdated infrastructure. The guide suggests reporting on solutions such as wastewater reuse, sustainable agriculture, and transboundary cooperation, while providing specific examples of water crises in the United States, Mexico, and South Africa.

The briefing highlights the vulnerability of sub-Saharan African food systems to climate change, noting that women bear a disproportionate burden despite their crucial roles. It critiques industrial agriculture for exacerbating inequalities and environmental degradation, proposing agroecology as a solution to enhance biodiversity, soil health, and food sovereignty.

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.
