Climate change is increasing the intensity of extreme precipitation across the U.S., with the Northeast and Midwest seeing the largest increases since 1958. Under 2°C of global warming, 85% of U.S. counties are projected to experience a 10% or higher increase in precipitation on the heaviest 1% of days. This intensification contributes to flash flooding and landslides, disproportionately affecting racial minorities and those in mobile homes, particularly in the South and rural areas. Between 1988 and 2021, warming-induced rainfall intensification caused an estimated $84 billion in inland flood damages.

Since 1970, spring temperatures in the contiguous U.S. have increased by an average of 2°F, with the most significant warming occurring in the Southwest. Analysis of 239 locations shows that 96% of cities experienced warming, with some locations in Nevada, Texas, and Arizona exceeding 6°F. This trend is characterized by an increase in warmer-than-normal spring days, which contributes to earlier snowmelt, prolonged allergy seasons, and extended agricultural growing seasons.

The U.S. experienced a record 28 billion-dollar disasters in 2023, causing over $93 billion in damages. Since 1980, tropical cyclones have been the costliest events, while severe storms are the most frequent. The document details how warming temperatures intensify specific hazards—such as increasing rainfall intensity and fueling stronger tropical cyclones—and notes that the average time between such disasters has shrunk from 82 days in the 1980s to 12 days in 2023.

The policy brief examines the 'stabilisation' phase of Somalia's offensive against Al-Shabaab, highlighting how resource competition among political elites and donors creates coordination failures. It identifies tensions between federal and state governments, donor-driven top-down approaches, and the risks of rushing interim administration formation in liberated areas, recommending a centralised stabilisation fund and a central coordinating body.

Analysis of 241 U.S. locations from 1970 to 2022 shows that fall temperatures have increased by an average of 2.4°F in 232 cities, with the most intense warming occurring in the Southwest. This trend is characterized by an increase in above-normal fall days, which prolongs risks related to heat-related illness, wildfires, and allergies, while increasing energy demand for cooling.

Analysis of FEMA heat data and Yale Climate Opinion Maps reveals a positive correlation (r = 0.12) between extreme heat exposure and worry about global warming in the U.S. However, a specific group of 217 counties—primarily in the Midwest and South—exhibit high exposure but lower-than-average worry. These counties, representing 6.4 million people, are characterized by higher proportions of white residents, rural populations, and 2020 Republican voters compared to the national average. The authors argue that these gaps in risk perception increase vulnerability to heat-related illness and death, necessitating tailored educational outreach and policy responses.

A lawsuit led by six federally recognized Indian tribes and Earthjustice resulted in a 2021 U.S. District Court ruling to vacate the Navigable Waters Protection Rule. The court found the rule contained "serious errors" and posed a risk of "significant harm to the nation’s waters." This ruling restored water protections that had been in place since 1986, specifically benefiting wetlands, headwater streams, and desert washes in the West, Southwest, and Great Lakes regions that had been excluded from Clean Water Act safeguards.

Climate Central's analysis of 150 U.S. weather stations shows that 90% experienced an increase in hourly rainfall intensity between 1970 and 2021, with an overall average increase of 13%. This trend is linked to the Clausius-Clapeyron equation, where warmer air holds more moisture, increasing the frequency and intensity of heavy downpours. Such extremes contribute significantly to flash flood risks, accounting for approximately one-third of U.S. flood damages ($73 billion) from 1988 to 2017. Future projections suggest that U.S. flash floods could intensify by 8% by 2100 under high-emission scenarios, with the Southwest and central U.S. identified as high-risk areas.

Between 1970 and 2021, growing degree days (GDD)—a measure of heat accumulation used to track plant and pest development—increased at 97% of 246 analyzed stations across the contiguous U.S. The average increase was 525 GDD, with the most significant rises occurring in the West, Southwest, and South. While some plants may benefit, increased GDD is linked to higher water and heat stress, altered agricultural schedules, and longer pollen seasons that exacerbate health issues like asthma and hay fever.

The Somalia National Adaptation Plan (NAP) Framework provides a roadmap for reducing national and local vulnerabilities to climate change. It emphasizes the integration of adaptation into the National Development Plan (NDP-9) and peacebuilding initiatives, recognizing that climate shocks exacerbate conflict and poverty. The framework outlines a whole-of-society approach, prioritizing gender-responsiveness, vertical integration between federal and state governments, and the mobilization of climate finance. It identifies the Directorate of Environment and Climate Change (DoECC) as the lead coordinator and proposes the establishment of a National Climate Fund and a dedicated monitoring and evaluation system to track progress.

The document examines the civil war in Cameroon's North-West and South-West regions, which began in 2017 following the violent suppression of protests against francophone domination. It highlights the deep-seated grievances of the anglophone minority, the failure of the 2019 Major National Dialogue, and the critical role of the diaspora in providing financial support, media coverage via the SCBC, and international advocacy. The author argues that the conflict is rooted in post-colonial flaws and recommends an international settlement, potentially including a new referendum.

The research paper examines the Anglophone separatist conflict in Cameroon, tracing its origins to long-standing grievances over marginalisation and 'Francophonisation'. It asserts that the escalation into civil war was triggered by the violent repression of peaceful protests in 2017 and is sustained by President Paul Biya's insistence on a military solution over political accountability. The author highlights the humanitarian toll, including over 3,000 deaths and 750,000 internally displaced persons, and calls for a joint UN and African Union framework to negotiate reforms regarding Anglophone autonomy and resource management.

Based on 2018 and 2019 survey data, the study finds that 64% of Americans believe global warming affects U.S. weather. Risk perceptions are heavily influenced by local geography, with residents in the West fearing droughts and wildfires, those in the Midwest fearing flooding, and those in the East and Southeast fearing hurricanes. While 56% of Americans view extreme weather as a high or moderate risk to their community over the next decade, the specific concerns vary by state, often reflecting local experiences with 'Billion Dollar Disaster Events'.

Analysis of 242 U.S. cities since 1970 shows that 81% have warmed by at least 1°F, with the highest increases in the Southwest. Additionally, 80% of 195 analyzed cities are experiencing their average last freeze earlier in the season, contributing to longer growing seasons and associated increases in seasonal allergies and pest activity.

Climate change is extending the freeze-free growing season in the United States, leading to longer periods of pollen exposure for nearly 20 million allergy sufferers. Analysis of 201 cities shows that 83% experienced longer growing seasons since 1970, with the most significant increases in the western U.S. Additionally, rising atmospheric CO2 levels are shown to increase the quantity and allergenicity of pollen from plants like ragweed.

The analysis finds that no new natural gas capacity is needed to maintain grid reliability in California through 2030. Depending on carbon caps and the use of battery storage to meet local capacity requirements (LCR), between 28 and 56 of the 89 modeled natural gas plants could be retired. While overall natural gas generation decreases, the report warns that remaining plants may cycle on and off more frequently, potentially increasing NOx emissions and harming air quality in nearby disadvantaged communities.

The document details how climate change is increasing the frequency and intensity of heat waves across the United States, leading to severe health risks and societal disruptions. It highlights the vulnerability of specific populations, such as the elderly and outdoor workers, and the role of the urban heat-island effect. The text argues that stabilizing carbon emissions and adhering to the Paris Agreement can significantly reduce the projected increase in extreme temperatures and the frequency of heat waves by mid-century.

The document examines how a warming atmosphere increases the frequency and intensity of extreme precipitation, contributing to higher inland flood risks in parts of the United States, particularly the Midwest and Northeast. It highlights that while climate change is a driver, land-use changes—such as development in floodplains and the removal of wetlands—significantly exacerbate flood risk. The report argues that current FEMA flood maps are inadequate because they rely on historical data rather than future projections. To mitigate these risks, the authors recommend reforming the National Flood Insurance Program, increasing funding for river gauge networks and flood mapping, and implementing nature-based infrastructure and stricter zoning regulations to discourage floodplain development.

The document examines the challenges RTOs face as the U.S. grid shifts from large central generators to variable renewables and distributed energy resources (DERs). It argues that 'flexibility'—the ability to respond to changes in supply and demand across various timeframes—is essential for reliability and cost minimization. The authors recommend eliminating self-scheduling for all generators and imports, preserving negative pricing, and improving the coordination between natural gas and electricity markets. It also suggests creating technology-neutral products that value specific capabilities, such as ramping and frequency response, and highlights successful examples like MISO's Dispatchable Intermittent Resource category and CAISO's Flexi-Ramp product.

New Mexico is experiencing a warming trend with an average annual temperature increase of approximately 0.6°F per decade since 1970. This shift is driving more intense droughts, reduced snowpack, and more frequent, destructive wildfires, which threaten the state's multibillion-dollar agricultural sector and forest ecosystems. The document recommends accelerating renewable energy investments, increasing energy efficiency, retiring coal plants, and implementing robust water management and monitoring systems to build climate resilience.
