Urban heat poses significant risks to public health, infrastructure, and overall quality of life, particularly in densely populated areas like Cambridge. By expanding its tree canopy, the city aims to reduce heat islands, improve air quality, and enhance community resilience against rising temperatures. The use of lidar technology has also highlighted inequities in tree coverage across neighborhoods, enabling targeted interventions. Without such measures, vulnerable populations, including the elderly and those with pre-existing health conditions, could face heightened risks during heatwaves.
