• Houston's Pleasantville neighborhood is grappling with extreme heat exacerbated by the urban heat island effect, which raises temperatures in densely built areas.
• Residents face soaring electricity bills and health risks as they struggle to cool older homes with inadequate insulation.

Impact & Risks

The urban heat island effect disproportionately impacts low-income and minority communities like Pleasantville, increasing health risks such as heat-related illnesses and respiratory issues. Older homes with poor insulation exacerbate the problem, leading to higher energy costs and financial strain. Vulnerable populations, including the elderly and those with pre-existing health conditions, face heightened risks during extreme heat events. The lack of sufficient weatherization assistance further compounds these challenges, leaving many residents struggling to adapt.
