The 2026 World Cup saw nearly half of its matches played on days with a climate change signal for temperature or dangerous humid heat. Over 55% of matches occurred in cities where daily highs exceeded the 82.4°F (28°C) athletic performance threshold, with 35 of those in non-climate-controlled stadiums. Miami Stadium was the hottest non-climate-controlled venue, with an average daily high of 93.4°F (34.1°C) and dangerous humid heat on almost every match day. The hottest single game was Paraguay vs. France in Philadelphia on July 4, 2026, reaching 101°F (38.3°C). France was the most heat-exposed team, playing seven of eight matches in non-climate-controlled stadiums, while the champion, Spain, faced lower heat exposure due to more games in climate-controlled venues.

GreenLatinos asserts that international climate spaces, such as UN COPs and specialized conferences, are critical for shaping policies and funding that affect Latino communities. The organization highlights the importance of the Belém–Antalya Mechanism and the Santa Marta Fossil Fuel Phaseout Conference in building momentum for a just transition and fossil fuel phaseout, while criticizing the lack of U.S. federal leadership under the Trump Administration.

Climate Central analysis shows that 14 of the 16 host stadiums for the 2026 World Cup are experiencing more extremely hot days during the June-July tournament period than in 1970. Human-caused climate change is responsible for an average of 49% of these extreme heat days across all stadiums, with the highest impact seen in Miami and Mexico City. In 10 repeat host cities, the frequency of extremely hot days has tripled on average since they last hosted the tournament.

The report finds that anthropogenic climate change has significantly increased the probability of dangerous humid heat during the 2026 FIFA World Cup compared to 1994. Using Wet Bulb Globe Temperature (WBGT) as a metric, the analysis indicates that more games are expected to exceed the 26C and 28C thresholds recommended by FIFPRO for cooling breaks and postponement, respectively. While air-conditioned stadiums may mitigate risks for players, spectators at outdoor events remain vulnerable. The study concludes that without substantial adaptation and rapid mitigation of fossil fuel use, hosting summer tournaments in the northern hemisphere will become increasingly hazardous.

The document highlights the health risks posed by extreme heat to players, workers, and fans during the 2026 World Cup, noting that cities like Monterrey, Dallas, and Miami could exceed 35 °C. It discusses FIFA's implementation of three-minute hydration breaks and the potential for shifting match structures to four quarters. Additionally, it addresses the environmental impact of the tournament, specifically the high pollution levels resulting from travel across three host countries, and links these temperature increases to the burning of fossil fuels.

The document advocates for a transformative approach to climate adaptation that moves beyond infrastructure to include 'communication justice'.

Analysis of 247 U.S. cities shows a significant increase in sweltering summer nights influenced by climate change, with average annual occurrences rising from one in the 1970s to approximately 27 currently. Nighttime temperatures have risen by an average of 3.1°F across 231 analyzed locations, with the Southwest experiencing the highest regional warming and Florida cities seeing the largest increases in climate-fueled warm nights.

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.

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 Central analysis shows that 88% of 242 analyzed U.S. cities have seen an increase in extremely hot days since 1970, posing significant risks of heat-related illness and death for student athletes, particularly youth and teens.

The Union of Concerned Scientists analysis finds that climate-driven sea level rise will expose over 1,600 critical infrastructure assets in the US to disruptive flooding at least twice per year by 2050. Public and affordable housing are the most vulnerable assets, with a disproportionate burden falling on disadvantaged communities. By 2100, the scale of risk depends heavily on global emissions, with the high scenario potentially affecting 15,081 assets. The report recommends science-informed planning, scaled-up funding, and a focus on reducing historical inequities to build coastal resilience.

Florida is expected to experience dangerous early-season heat from May 14-16, 2024, with temperatures exceeding 90°F and heat index values between 100°F and 105°F. Human-caused climate change has made these conditions more than five times more likely, as indicated by a Climate Shift Index (CSI) level of 5 in Central and Southern Florida. Approximately 17 million people are expected to experience at least one day of CSI level 5 heat. The event is characterized by high humidity and overnight lows 5°-10°F above average, increasing the risk of heat-related illnesses and mortality, particularly for those without effective cooling.

The document outlines ten prevalent climate myths, attributing their spread to fossil fuel companies and political allies to confuse the public and press. It counters these myths with scientific consensus, noting that over 99% of climate scientists agree human activity is overheating the planet. The guide emphasizes that while the climate has changed naturally in the past, the current rate of change is unprecedented in 66 million years due to 250 years of fossil fuel combustion. It asserts that the tools to limit global warming to 1.5 degrees Celsius exist and that renewable energy is increasingly cost-competitive with oil. Geographically, it highlights the United States as the largest historical emitter of greenhouse gases, followed by China, and notes that current warming of approximately 1.2 degrees Celsius is already intensifying extreme weather globally.

Climate Central analyzed 18,945 census tracts across 44 major U.S. cities, finding that 41 million people (approximately 55% of the analyzed population) live in areas where the urban heat island (UHI) effect increases temperatures by 8°F or more. The study identifies albedo, green space percentage, and population density as the primary drivers of this effect, with New York City exhibiting the highest average UHI index. The analysis categorizes cities by heat patterns—concentrated cores, diffused zones, or sprawling intensity—and highlights that structural inequities often lead to disproportionate heat exposure for people of color and low-income populations.
