heat island

In a statement, the WMO added: "The effect of heat on human health is more pronounced in cities as a result of the urban heat island effect. This is where urban environments are significantly warmer than surrounding rural areas, especially during hot periods, due to an abundance of paved surfaces, buildings, vehicles, and heat sources."

That is because of something called the urban heat island effect.

Dehydration and heat stroke can occur when temperatures rise, and urban heat island effects can also help to trap pollution leading to poor air quality.

In cities, the trend is compounded by the fact that the built environment absorbs and retains more heat than the rural area around it, a phenomenon known as the urban heat island effect.

The lawsuit states that the revelation concerning the drop in carbon sequestration necessitates environmental review, and that the modifications — described as attempts to mitigate what’s known as the urban heat island effect — also require analysis under CEQA.
