Urban Heat Islands and Their Effects

Dr. Jeremy Hoffman discusses the concept of urban heat islands, where over 80% of Americans live. These areas are significantly warmer due to urbanization, which alters natural landscapes and affects heat balance. The video highlights the environmental and health consequences of urban heat islands, especially during extreme heat waves. It suggests mitigation strategies like planting trees, using reflective roofs, and reducing emissions. The video concludes with a call to action for individuals and lawmakers to address these issues.
