Understanding Urban Heat Island (UHI) Effect - Causes, Impacts, and Solutions
The Urban Heat Island (UHI) effect, illustrated through images and descriptions, explores the formation of heat bubbles over cities, its causes like dark materials and vegetation loss, effects on clouds and rain, and comparison with heat waves. The issue, both anthropogenic and natural, is highlighted, and the potential problems it poses are discussed.

Urban Heat Island (UHI) STEVEN GOLUSKA
What causes the UHI Effect Increase in dark materials to trap heat and reradiate later Increase in thermally conductive materials Decrease in vegetation Decrease in surface water
UHI Effect or Heat Wave UHI Anthropogenic (human caused) Caused by building materials and vegetation/ surface water loss. Only occurs in urban environments. Heat Wave Natural Caused by high pressure systems staying in place. Can happen in urban or natural environments
Is UHI Effect a true problem? About the human population on Earth dwell in cities.1 Large cities across the globe. Data interpretation issues? Potential other effects on a broader scale?
How can we mitigate the UHI Effect? Reflective materials Environmental heat sinks Increase parks and planted environments Road colors Roof top gardens
Teaching through investigation Needed materials
Teaching through investigation Data gathering Take temps at dots, also let students take temps anywhere else they would like.
