Obvious changes due to UHI:

Densely populated cities will show 1°C–3°C temperature increase compared to rural areas.
Increased energy demand (mainly from cooling).

Reduced wind speeds (lack of "urban breezes" or low-level hurricanes).

Poorer air quality (due to heat-driven chemical reactions like ozone formation).

Case studies will confirm that green infrastructure (trees, reflective roofs) significantly mitigates UHI.

Detailed effects of UHI

[ Temperature patterns ]

• Downtown cities will record the highest temperatures, followed by urban residential, suburban, and rural zones.

• Heatmaps will most likely show that the areas with the highest temperatures are in dense construction areas, with limited greenery and heavy traffic.

[ Neighborhood Vulnerabilities ]

• Low-income neighborhoods, often with less green space and poorer housing infrastructure, are more affected by UHI.

• These areas experience higher costs of cooling during high temperatures, with few alternative options for cooling.

[ Health Impacts ]

• Higher temperatures will lead to an increase in heat health impacts like heat strokes and dehydration, which will be more prone to happen to vulnerable groups like young children, the elderly, and people with existing health issues.

• Air pollution that is intensified by increased heat will likely increase the risks of cardiovascular issues and asthma.

[ Mortality ]

• UHI effects directly increase the chances of mortality during heat waves. For example, ~70,000 deaths were estimated during the 2003 European heatwave, heavily concentrated in urban zones.

• ~37% of global heat-related deaths from 1991–2018 were related to climate change, with UHI intensifying local impacts.
