- Climate Central estimated that approximately 1,950 shootings in the 100 most violent U.S. cities from 2021 to 2025 are attributable to higher temperatures caused by climate change, representing about 1.7% of total gun violence in those cities during that period.
- Philadelphia experienced a heat dome in July with temperatures over 100°F for three days, during which nine shootings occurred, and the city’s climate-linked temperature rise of 2.7°F is associated with an estimated 149 additional shootings over five years.
- Kristina Dahl of Climate Central stated that climate change has made the typical day in studied cities 2.4°F hotter on average, increasing the risk of gun violence, with warming ranging from 1.7°F in San Francisco and Miami to 3.8°F in Fresno.
- Marion Campbell of Eddie’s House in Philadelphia explained that economically vulnerable populations often lack air conditioning, and heat increases irritability and reduces emotional regulation, contributing to violence.
- John Roman of NORC at the University of Chicago confirmed the established link between heat and violence, noting that even with lower overall gun violence this summer, climate change is likely suppressing what would otherwise be even lower rates.
- Kimberly Meidenbauer of Washington State University described how chronic stress from poverty, discrimination, and environmental heat overload the body’s ability to regulate emotions, making extreme heat more likely to trigger violent responses in overburdened communities.
Why it matters: An estimated 1,950 additional shootings are tied to climate change across 100 U.S. cities, meaning public safety is now directly shaped by global warming. Disadvantaged communities—already facing higher heat exposure and systemic underinvestment—bear the brunt, turning climate inaction into a public health and equity crisis.
