Forecasters said the high for Phoenix had risen to 111 degrees (44 Celsius) by midafternoon Thursday and was not expected to hit Wednesday’s record high for the day of 116.Phoenix officials say they are tackling urban warming, monitoring downtown temperatures, planting thousands of trees and capturing rainwater to cool off public spaces.Elsewhere, Chicago maintains more than 500,000 trees to offset rising temperatures and is a national leader among cities for so-called green roofs covered with vegetation. According to the Georgia Institute of Technology’s Urban Climate Lab, the pace of warming in Phoenix is happening at an alarming speed – three times that of the earth as a whole, to be more exact.

The reason for an increasing UHI is the growth of Phoenix as we build out farther and farther into the desert valley. So far this year, five people have died in Maricopa County from heat-associated causes, and another 34 cases are being investigated, public health officials said.“If similar numbers of people died from any other type of weather event, “it would be considered a national disaster,” noted Phoenix sustainability officer Mark Hartman.The danger is especially acute for people like the homeless and elderly. High evening temperatures caused by urbanization account for most of the differences in the urban-vs.-rural warming rates.Special circumstances in desert cities alter the character of the UHI, both in general and its character throughout the day. Not surprisingly, Phoenix is a textbook example of the urban heat island, with the effect of the heat island reaching as far as 25 miles from Sky Harbor International Airport. Heavily irrigated residential areas are coolest, due both to evaporating surface water and the shading effect of trees. There aren’t enough trees to provide shade and evaporative cooling that can bring down temperatures.“We are working against a pronounced warming trend in large cities, and so it will require a substantial resurfacing of urban environments simply to slow the rate of warming,” Stone said.He said the heat island effect prevents a city from peeling off the day’s furnace-like heat after the sun sets, driving up temperatures over time. There is a slight mitigation of daytime temperatures in the urban center and xeriscaped residential areas due to evaporation of surface water, shading, and heat-absorption rate into the built surfaces.

For example, the highest daytime temperatures in our region often occur in the natural desert rural areas.

“There’s usually a line around the block during the giveaways.”Koetter said Louisville was the first major city to commission a heat management study, which was done by Stone’s climate lab. PHOENIX (AP) — When temperatures soar as they have this week in downtown Phoenix, homeless people ride the air-conditioned light rail to avoid a heat so brutal it killed 155 people in the city and surrounding areas last year. ‘Urban island effect’ compounds Phoenix’s sweltering heat Originally published July 25, 2018 at 11:42 pm Updated July 31, 2018 at 1:16 pm Share story
His team’s research shows Phoenix temperatures rising nearly 1 degree per decade, consistently placing it alongside Dallas and Louisville, Kentucky, as some of the fastest-warming U.S. cities. In residential areas, the density of housing, even spacing of vegetation may act to curtail rapid cooling to the nighttime sky.These higher temperatures affect those who live in cities in many ways, influencing their health and comfort, energy costs, air quality and visibility levels, water availability and quality, ecological services, recreation and overall quality of life. Already devilishly hot for being in the Sonoran desert, Arizona’s largest city is also an “urban heat island,” a phenomenon that pushes up temperatures in areas covered in heat-retaining asphalt and concrete. Within the built urban area, radiation trapping by the buildings and the large heat stored in these features during the day inhibit cooling, and this results in the urban area being warmer than the surrounding areas at night.Temperatures in the urban core are the highest, with the residential areas being somewhat cooler and open areas being coolest. The agricultural areas have the highest surface moisture, but without shading of the surface, the temperatures sometimes may be higher than in the residential areas.The situation at night is different from the day. Already devilishly hot for being in the Sonoran desert, Arizona’s largest city is also an “urban heat island,” a phenomenon that pushes up temperatures in areas covered in heat-retaining asphalt and concrete.
He said his group plants 2,500 trees such as oak, elm, pecan and ash annually.Louisville has planted some 10,000 trees over the past three years — including maples, oaks, elms and Kentucky coffee trees — and sometimes pairs with nonprofit groups to give away trees for smaller areas, such as dogwoods, said city sustainability officer Maria Koetter.“I really think the community is getting the message about trees,” Koetter said. Many people associate Phoenix with cactus, but acacia, blue palo verde, ironwood, desert willow and other trees thrive here.Aimee Esposito, executive director of non-governmental Trees Matter, said her Phoenix organization this year plans to give 5,000 small trees to residents across the area’s Valley of the Sun, and will plant more at schools through educational programs.Matt Grubisich, director of operations and urban forestry for the nonprofit Texas Trees Foundation in Dallas, said planting trees is the easiest and most effective action to ease urban heat.
