Violent crime increases proportionally to air temperature, adding to police budgets and increasing the likelihood of police violence incidents. (Anderson & Anderson 1984, Cotton 1986)
Heat waves increase the load on hospitals. The California heat wave in 2006 caused 16,166 excess emergency department visits and cost hospitals $5.4 billion dollars.

The elderly, pregnant, and young are vulnerable to extreme heat. People over 65 make up most of the heat-related hospital visits and fatalities that occur during heatwaves. (Semenza 1999)
The cost of electricity to run buildings is three times higher in summer than in spring and will continue to increase with rising electricity prices and warmer temperatures. The US loses $680 billion dollars a year to wasted electricity. (McKinsey 2008)
Summer CO2 emissions in California jump up to twelve-fold on hot days when AC use is high. Increasing levels of urban heat, population, and urbanization will increase grid-produced CO2 emissions. @EnergyLollipop (California ISO, July 2020)
Urban heat amplifies the economic costs of climate change by three-fold and is projected to reduce GPD by as much as 10.9 percent in some cities. (Estrada, Nature Climate Change 2017.)
People of color and low-income populations are affected disproportionately by urban heat. Over 700 people died in the 1995 Chicago heat wave, most of whom were
African Americans. (Klinenberg, 2015)

Heat increases the chemical reactions that create smog. In 2002, 288 million Americans were exposed to high ozone smog, which hastened death for 795 people, caused 4,150 hospitalizations, and cost $6.5 billion. (Knowlton, NDRC, 2011)
Greenery increases property values. A study on Riverside County, CA found that pro to trees resulted in an increase of $16m in total land value to the county. Tree cover increased property $ by 7% in residential areas and 18% for building lots. (Standiford, Scott, Berkeley 2002)
