Mapping urban heat from space reveals dangerous inequities in LA public parks
A study using satellite data reveals that public parks in underserved areas of Los Angeles reach dangerously high temperatures due to heat-retaining materials like artificial turf and concrete, exacerbating environmental inequities. Parks in South LA averaged 105.8°F in summer, compared to 91.6°F in West LA, with natural surfaces in the latter providing cooling benefits.

“A new study has found that public parks in underserved areas of Los Angeles can reach dangerously high temperatures, in some cases hot enough to cause pain or burns, because of the materials used to build them.”
VERIFIED BY REFERENCE
Wikipedia entries about Los Angeles, Metro, and the Public Library do not mention park materials, temperatures, or heat-related hazards in underserved areas.
