Trees are beautiful, but are they also a cure for climate change related health hazards? We know that trees beautify urban spaces, increase property values, reduce stress, improve mental health, and benefit communities by reducing crime rates and increasing social cohesion. But tree cover can also provide significant cooling benefits to offset dangerous temperatures during extreme heat events, which are on the rise in urban areas as a result of climate change.

Human exposure to waterborne illnesses will increase as climate change creates more extreme precipitation events that drive harmful pollutants that into fresh waters used for drinking, bathing, swimming, and boating. Rising global temperature is also predicted to promote the growth of pathogens and toxic algae blooms in freshwater. Communities recognizing these threats are establishing adaptation plans and policies to prevent increased risks to human health as the climate changes.

Social and emotional learning (SEL) has a strong association with outcomes important to public health, from increased high school graduation rates to reduced drug use. This Quick Reference outlines the Network’s project to review policies and laws related to SEL.

Solar energy production can reduce public health risks caused by climate change. This Quick Reference resource provides an overview of the legal strategies that have been implemented by communities to promote renewable energy and equitable public health outcomes.

When natural disasters occur, entire electrical grid systems (including those powered by solar energy) can shut down. Solar energy stored in batteries, which operate independent of the grid, have become an increasingly important, reliable back-up system for maintaining the health and safety of communities in emergencies. Solar batteries also help reduce public health harms caused by climate change and the use of fossil fuels.

There are distinct differences in how U.S. laws do (or don’t) protect individuals from drinking water contamination. While a landmark federal law, the Safe Drinking Water Act, generally protects individuals who use a public water supply from exposure to unsafe levels of regulated contaminants, there is no similar protection for the approximately 45 million U.S. residents who rely on private wells for water. This gap in regulatory oversight increasingly burdens rural households, where the risk of exposure to nitrate contaminates is highest.
