The document, prepared by Paraguay for the 33rd meeting of the Conference of the Parties in Asunción, argues that the World Meteorological Organization (WMO) meets the criteria under Article XI of the IAI Agreement to become an Associate. It highlights the WMO's regional presence in the Americas, its global leadership in climate cooperation through the Global Framework for Climate Services (GFCS), and a history of collaboration with the IAI since 2022, including joint research on health, climate, and drought management.

A briefing prepared by the permanent representative of the United States for the 33rd meeting of the Conference of the Parties to the Inter-American Institute for Global Change Research (IAI), proposing that the American Geophysical Union (AGU) be invited to become an Associate of the Institute.

A December 2024 survey of registered U.S. voters found that 55% believe federal agencies should increase their efforts to protect people from the health harms of global warming, while only 15% believe they should decrease these efforts. Support for increased federal action varies significantly by political affiliation, with 86% of liberal Democrats supporting more action compared to 22% of conservative Republicans.

A December 2024 survey of registered U.S. voters found that 55% believe federal agencies should increase their efforts to protect people from the health harms of global warming, while 75% want these agencies to either maintain or increase their current efforts. Support for increased federal action varies significantly by political affiliation, with the highest support among liberal Democrats (86%) and the lowest among conservative Republicans (22%).

The brief argues that the 'Wind Directive'—which suspends all federal wind permitting—violates the Administrative Procedure Act (APA) by deviating from established review processes without a reasoned explanation. Amici assert that wind power is a cost-effective, critical energy source with significant public health and climate benefits. They further argue that the directive's claims regarding wind energy's impact on whales and birds are scientifically unsupported, citing findings from NOAA and the GAO. Finally, the brief highlights a contradiction in federal policy, where the administration fast-tracks fossil fuel projects while blocking wind energy, despite the latter's superior economic and environmental profile.

Between 2020 and 2024, climate change increased the number of 'pregnancy heat-risk days'—days exceeding the 95th percentile of local temperatures—in every analyzed country. In 90% of countries and 63% of cities, these risk days at least doubled compared to a world without climate change. The most significant increases occurred in developing regions, particularly the Caribbean, where 15 countries saw an average of at least 60 additional risk days annually, representing roughly one-fifth of a typical pregnancy. Beyond heat, the report notes that climate-driven air pollution, flooding, and infrastructure damage further threaten maternal health and birth outcomes.

A cross-community statement from civil society, the private sector, and the technical community calling for the alignment of the Global Digital Compact (GDC) with the WSIS process to avoid fragmentation in digital governance. The authors advocate for the IGF to be established as a permanent forum with sustainable resources to maintain its role as a primary multistakeholder platform for digital cooperation.

An event attribution study found that human-induced climate change increased the likelihood of the April 2025 extreme rainfall in the Central Mississippi river valley by approximately 40% and its intensity by 9%, though observational data suggests these increases could be as high as a factor of 2 to 5 in likelihood and 13-26% in intensity. The event caused at least 24 fatalities and estimated economic damages between $80 and $90 billion, with significant agricultural losses in Arkansas. The study highlights that while climate change amplified the event, effective early warnings from the US National Weather Service prevented a larger catastrophe, despite current staffing shortages in NWS field offices.

The document outlines the cyclical relationship between climate change and wildfires, highlighting how rising temperatures and droughts increase fire frequency while the resulting emissions accelerate global warming. It focuses on the US-Mexico border region—specifically Southern California, Arizona, and Northern Baja California—where smoke stagnation and limited healthcare access disproportionately affect migrants, outdoor workers, and marginalized urban populations in cities like Tijuana, Nogales, and El Paso. The guide suggests journalistic angles for investigating cross-border firefighting coordination between agencies like CAL FIRE and CONAFOR, the health impacts of smoke on vulnerable groups, and the effectiveness of local air quality monitoring tools.

The document outlines the global feedback loop between climate change and wildfires, while highlighting the specific vulnerabilities of border communities and migrants in the US-Mexico region. It provides a framework for reporting on transboundary air pollution, the health risks of smoke exposure for marginalized groups, and the role of cross-border fire management coordination.

The analysis reveals a significant increase in fire weather days across much of the contiguous U.S., with the western U.S. experiencing far more frequent fire weather than the east. While the western U.S. has seen strong increases, particularly in the Southwest during spring and summer, parts of the eastern U.S. have also seen impactful increases, especially in the Southeast and Northeast. The study emphasizes that while human activity causes 87% of wildfires, fire weather primes the landscape for these fires to ignite and spread.

A growing number of US communities and governments are suing fossil fuel companies, arguing they misled the public about climate change. These 'polluter pays' cases seek compensation for climate damages, mirroring the 1990s tobacco litigation. While most cases are in the US, a significant case in Peru involving RWE highlights global implications. The fossil fuel industry is responding with lobbying for legal immunity and efforts to discredit litigants, though some cases, such as Honolulu v. Sunoco LP, are advancing toward trial.

A coalition of 54 organizations opposes budget reconciliation recommendations from the House Committee on Natural Resources that would expand coal leasing on federal lands, reduce royalty payments for coal companies, and mandate the approval of specific mining projects. The authors argue these measures contradict climate goals and economic trends, noting that coal produces less than one-fifth of U.S. electricity but over half of the electric power sector's CO2 emissions. Specifically, they oppose the mandate for the Bureau of Land Management (BLM) to make four million acres available for leasing, the reduction of maximum royalty rates to 7 percent, the expansion of the Bull Mountains coal mine in Montana, and the reopening of the Powder River Basin to new leasing.

The document warns that the plastics and petrochemical industries are using tactics similar to those of the fossil fuel and tobacco industries to influence the Global Plastics Treaty negotiations. It highlights a significant increase in industry lobbyists at the INC-5 session, who outnumber delegations from the European Union, Pacific Islands, and Latin American countries. The brief recommends incorporating conflict-of-interest protections directly into the treaty's preamble, scientific bodies, and articles concerning financial mechanisms and technology transfer to ensure the agreement's effectiveness in protecting public health and the environment.

The report details a spatial targeting strategy for phosphorus reduction in the Canadian Prairies, using the Swan Lake study area as a pilot. It integrates the PTMApp model with HEC-HMS and HEC-RAS to account for regional hydrological specifics, such as spring runoff and non-contributing areas. Key findings highlight that default PTMApp settings may overestimate BMP efficiency during spring runoff and that high-quality land-use data is critical to avoid significant errors in nutrient load estimates. The report also discusses the practical application of these models for government and First Nations stakeholders, emphasizing the value of local knowledge and the need for compensation programs to encourage BMP adoption on high-value cropland.

The document highlights the rapid degradation of wetlands in Myanmar, noting a 25% loss in the Upper Chindwin River basin between 2000 and 2020. It critiques existing government-led initiatives for being tokenistic and limited primarily to Ramsar sites, leaving smaller wetlands vulnerable. Based on a project in the Hkamti region, the authors demonstrate that community leadership—through village working committees and alternative livelihood planning—enhances resource management and monitoring. The brief recommends establishing a community-led management framework, diversifying funding, and integrating wetland conservation across sectoral policies like agriculture and tourism.

The report finds that while a majority of Armenians recognize the impacts of climate change—particularly on health—and support renewable energy, actual personal engagement in environmental activities remains low at 22%. Public trust in environmental action is highest for educational institutions and lowest for the private sector and NGOs. Significant barriers to participation include a lack of time, financial costs, and indifference.

The report finds that while a majority of Moldovans (61%) perceive their understanding of climate change as good or very good, actual engagement in environmental activities is around 57%. Public priorities for environmental protection are led by access to clean water and sanitation and waste management. There is significant concern (65%) regarding dependence on foreign energy sources, with strong support for developing solar and wind power. Educational institutions are viewed as the most important actors in driving environmental action, while corporate sustainability initiatives receive the highest level of public support. Barriers to individual engagement include a lack of time (62%) and financial costs (34%).

The report finds that while a majority of Ukrainians acknowledge the personal impacts of climate change and support renewable energy development, significant barriers such as financial costs and a perceived lack of common practice hinder individual engagement. Public trust in environmental action is highest for volunteers and youth activists, while the central government is viewed as moderately important but less efficient. Energy security is a major concern, with a strong preference for solar and wind power to reduce foreign dependence.

Climate Central analyzed 243 U.S. locations and found that 67% have already shifted to warmer planting zones between 1951-1980 and 1995-2024. Projections based on the SSP2-4.5 pathway suggest 90% of these locations will shift to warmer zones by mid-century (2036-2065), with the Upper Midwest expected to see the most significant warming.
