ENVIRONMENTAL JUSTICE AND CIVIL RIGHTS ADVOCATES’ RESPONSE TO PETITION FOR RULEMAKING TO RESCIND EPA’S TITLE VI DISPARATE IMPACT REGULATIONS
A coalition of advocates argues that the EPA's disparate impact regulations under Title VI of the Civil Rights Act of 1964 are essential for protecting marginalized communities from disproportionate environmental harms. The document details systemic environmental racism, provides case studies of both successful and failed civil rights enforcement, and urges the EPA to strengthen rather than roll back these protections.

Monthly Attribution Overview - August 2024
The report finds that August 2024 temperatures were elevated across much of the U.S., particularly in the South and Southwest, with Texas experiencing the highest anomalies. Using the Climate Shift Index (CSI), the analysis shows that the Southwest and South had the highest number of days where temperatures were at least three times more likely due to climate change. San Juan, Puerto Rico, recorded its hottest August on record, and Amarillo, Texas, was the most unusually hot city, 6.27°F above normal.

Disenfranchised by Climate Change
The report examines the intersection of climate change and democratic processes, detailing how extreme heat, floods, and wildfires disrupt voter registration, polling access, and ballot counting. It provides evidence of recent climate-driven disruptions in the US, India, and Pakistan, and analyzes temperature anomalies in 60 countries during the 2024 election cycle. The authors advocate for systemic changes, such as flexible voting arrangements, improved risk mapping, and updated emergency statutes, to protect the fundamental right to vote on a warming planet.

Visualising Extreme Heat
The document argues that extreme heat is often visually misrepresented as 'fun' or treated as a simple weather story, despite being the deadliest of climate extreme events. It advises visual storytellers to move beyond clichés by focusing on the most vulnerable populations—such as outdoor laborers, the elderly, and the poor—and by documenting the systemic impacts on health, transport, and employment. The guide emphasizes the importance of balancing images of risk with visuals of concrete interventions, such as cooling centers and shade structures, to avoid overwhelming audiences. Additionally, it suggests expanding the timeframe of shooting to include nights and planning access to institutions like hospitals and care homes before heat seasons begin.

Extreme heat and fires linked to climate change in Brazil
Between August 22 and 25, 2024, over 60 million people in Brazil faced extreme temperatures and wildfires exacerbated by climate change. High temperatures were forecasted to be five times more likely due to global warming, with anomalies reaching up to 10°C above normal in São Paulo. Wildfires have burned over 760,000 hectares in the Amazon and 1.3 million hectares in the Pantanal, with climate change increasing Pantanal fire intensity by 40%. On August 20, PM2.5 pollution levels reached 11 times the World Health Organization's recommendations, causing increased respiratory illnesses and affecting 10 Brazilian states as well as Bolivia, Paraguay, and Peru.

Heat Season Power Outages
The United States saw a 60% increase in major weather-related power outages during the heat season between 2014-2023 compared to 2000-2009. The South region experienced the highest number of these events, with Texas and Michigan recording the most outages at the state level. These outages compound health risks for vulnerable populations, such as the elderly and children, particularly when overlapping with extreme heat waves. Proposed solutions for grid resilience include the implementation of microgrids, smart grid technologies, and physical hardening of infrastructure.

Cooling Schools in a Hotter Climate
Climate Central analyzed cooling degree days (CDD) across 243 U.S. locations, finding that 95% experienced increased cooling demand during the back-to-school period (July 17 to September 8) since 1970. Over the last decade, human-caused climate change increased this demand by approximately 34%. The report highlights that extreme heat negatively impacts children's learning and health, while many U.S. schools lack the necessary HVAC infrastructure to adapt to these rising temperatures.

Monthly Attribution Overview - July 2024
The report finds that July 2024 temperatures were elevated in the eastern and western thirds of the United States, with the West Coast showing particularly high anomalies. Using the Climate Shift Index (CSI), the analysis identifies the Southwest as having the strongest climate signal, with cities averaging at least 14 days where temperatures were at least three times more likely due to climate change. Specific cities like Spokane, Washington, and Reno, Nevada, showed significant temperature anomalies and long-term warming trends since 1970.

Rising Heat Risks for Workers
Climate Central reports that 89% of 242 analyzed U.S. locations have seen an increase in annual 'warning days' (heat index 80°F to 94°F) since 1979, with the most significant rises in the Ohio Valley and Upper Midwest. Between 1992 and 2022, 986 U.S. workers died from heat exposure, and from 1980 to 2016, an average of 421 million work hours were lost annually, costing $14 billion. The document highlights a lack of comprehensive federal heat standards, noting that only five states have such protections, while some states like Florida and Texas prohibit local municipalities from enacting their own heat safety laws.

Climate Change in the American Mind: Beliefs & Attitudes, Spring 2024
The report finds that a majority of Americans believe global warming is happening and is mostly human-caused, with significant numbers reporting personal experience with its effects and emotional distress. While many feel a personal responsibility to act, there is a notable gap in understanding the strength of the scientific consensus, and a majority rarely discuss the issue with family and friends.

Urban Heat Hot Spots in 65 Cities
Climate Central analyzed the urban heat island (UHI) index across 65 major U.S. cities, finding that 68% of the 50 million residents in these cities live in areas where the built environment increases temperatures by 8°F or more. The study identifies albedo, green space, and population density as the primary drivers of this effect. It also highlights a link between historical redlining and current heat disparities, noting that in 84% of 179 analyzed cities, historically redlined areas experience hotter summers than non-redlined areas.

Sleepless Nights
Climate change is increasing the frequency of nighttime temperatures exceeding 18°C, 20°C, and 25°C, which impairs human sleep and increases health risks. Between 2018 and 2023, the average person globally experienced 4.8 additional days per year above 20°C and 11.5 additional days above 25°C due to climate change. The report highlights severe impacts in specific regions, such as California in the U.S. and West Bengal and Assam in India, where the number of added hot nights is highest.
