1. Urban heat island

   An urban heat island is a metropolitan area that is significantly warmer than its surrounding rural areas due to human activities. The phenomenon was first investigated and described by Luke Howard in the 1810s, although he was not the one to name the phenomenon. The temperature difference usually is larger at night than during the day, and is most apparent when winds are weak. UHI is most noticeable during the summer and winter. The main cause of the urban heat island effect is from the modification of land surfaces, which use materials that effectively store short-wave radiation. Waste heat generated by energy usage is a secondary contributor. As a population center grows, it tends to expand its area and increase its average temperature. The less-used term heat island refers to any area, populated or not, which is consistently hotter than the surrounding area. Monthly rainfall is greater downwind of cities, partially due to the UHI. Increases in heat within urban centers increases the length of growing seasons, and decreases the occurrence of weak tornadoes.

2. Kamil Kaloush:

   Palm trees do not sequester carbon at the same rate as our native canopy trees and do not provide shade, cool down streets and sidewalks to help counter the urban heat island effect that canopy trees do.

4. Stephen Sheppard:

   With climate change, we know we are going to get three, four degrees increased temperatures minimum on average, which means a lot more heat waves, about the only low-cost way to deal with that is increasing and improving a healthy canopy of trees because they reduce temperatures and the urban heat island effect.

5. Derica Peters:

   They can also allow for water flow, which has a positive effect on storm water management, and cool the surface temperature. as we are well aware that the urban heat island is here, and as we’re simultaneously trying to prevent it and mitigate it, we have to be able to respond to it as it does impact the public and our infrastructure.
