Sunday Long Read: Desert Of The Real

Saritha Ramakrishna.  What future can cities like Phoenix have in a world where climate change makes this metro area of nearly 5 million less and less sustainable -- and survivable -- every year, especially for those who can't afford to relocate?

My father once showed me an 8 ½” x 11” photo of a McDonald’s drive-through sign, set against a landscape of red dust. There was nothing around for miles; yellow arches were the only humanizing marker in an endless plain. He asked me where I thought the picture was taken. I had no idea. He later showed the picture to our neighborhood friends at a party and explained that it was land he was considering purchasing south of our home in Chandler, AZ. They nodded, asking about prices and contracts with polite interest. Once this had gone on long enough, he revealed he had actually edited those golden arches onto a stock image of Mars. I cringed, all the adults laughed. It was a summer day. The sun burned with its typical intensity, insistent on my skin. The cracked concrete around the pool tessellated outward like the Martian ground. I let my feet dangle in the water, watched them become silhouettes, ghostly in the unnatural blue. All seemed well.

Years later, on July 20, 2017, temperatures in the City of Phoenix reached 119 degrees, the fourth hottest day the city had ever experienced. The city’s national weather service branch represented the highest temperatures in a shade of brilliant magenta. These areas were designated as “rare, dangerous, and possibly life threatening.” All of Phoenix and its surrounding suburbs glowed pink
.

People retreated into their homes and let the air conditioning circulate. They dove underwater, and hoped for the best. Days like these are stagnant, the air immobilizing. It presses against the body and asphalt, radiating through a network of suburban homes in Gilbert, Chandler, Tempe, the Encanto, and elsewhere in the Valley of the Sun. Cul-de-sacs turn ghostly; the sidewalks catch the light, shimmer like water. For those waiting at the light rail or bus stops, shade provides temporary relief, though it’s a landscape not meant for continuous exposure. In order to save on air-conditioning bills, towels are soaked in ice water, dripped across overheated skin. Elsewhere, water falls from restaurant misters, flows cyclically around the waterpark rivers of Sunsplash and Big Surf.

The city of Phoenix sweltered under these impossibly hot skies, as temperatures climbed in a historic upward trajectory. Every year the city experiences an average of three months of temperatures over 100 degrees, or “triple-digit days” as local weathermen describe them. By 2060, it’s expected that three months will turn into four-and-a-half months.

I grew up in Chandler, AZ, one of many linked suburbs in greater Phoenix. Chandler is composed of networks of pools and round-edged subdivisions. Summers brought the acridity of settling chlorine in sinuses, sweat drying in artificially cooled air. In the Valley of the Sun, heat, wealth, and water move together and apart, repelling and attracting each other, shaping housing markets and their occupants’ bodies and livelihoods.

In friends’ backyards and community pools, the better-off among us gossiped and played Truth-or-Dare, fought over outcomes of Sharks-and-Minnows and Marco Polo. We spent our time hiding from each other amongst the greenery of neighborhood parks, or remained captive indoors, tethered to desktop monitors. On such July days, we lived half-online, half-underwater.

I was in Cambridge, Massachusetts during last year’s heat wave. I sat in my work cubicle refreshing social media feeds every few minutes, clicking through the photos and articles that materialized. In pixelated appreciation I scrolled past videos and photos of recycling bins melted into trickling blue goo, kids frying eggs on sidewalks and on the dashboards of cars. I had been admitted to MIT’s Department of Urban Studies and Planning a few months prior, intending to study climate change. That day, I imagined the entire city melting, congealing into indistinguishability. 
Not long after, I spoke with Dr. Nancy Selover, Arizona’s State Climatologist about this heat wave and the increasing temperatures in the state. She told me that the difficulty of extreme temperatures is that they “typically come in a heat wave” which puts residents at greater health risk. (In 2016, Maricopa County, which includes the Phoenix-Metropolitan area, reported 130 heat deaths, the highest count of the past 15 years.) The city’s record high was an impossible 122 degrees in 1990, which has yet to be broken, though she warned that “we’re edging towards probably matching that in the next couple years.” Without adaptive or mitigating measures, by the end of the century the city could be six to eight degrees warmer. Its infrastructure contributes to variations in heat exposure, via Phoenix’s well-acknowledged urban heat-island effect, a phenomenon where paved surfaces trap heat that is slowly released overnight.

“The impact of the heat island in terms of warming the City of Phoenix is almost an order of magnitude greater than climate change, greater than global or regional warming,” Dr. Selover said. Though she does not expect that this will remain the case, this notion is counter to narratives that frame climate-related issues as matters of individual choice, as opposed to summative infrastructural ones. All of Phoenix’s development and its storied overlays play a role in these hazards—developers, sellers, and homebuyers alike.

The city government has acknowledged the heat island, and the importance of canopy coverage to mitigate it. It disproportionately affects the poor, whose neighborhoods do not have the tree and shade coverage of richer areas, where air conditioning bills are an undue financial burden. Dr. Selover pointed out, “We have some older neighborhoods that have been here for years and years and years and they have a lot of turf grass, and they have a lot of big leaf trees, and they have a lot of shade, a lot of cooling,” while “the poorer communities, a lot of the minority communities don’t have the benefit of that shade.”

What I've seen time and time again is that when it comes to the effects of climate change, it's those with the fewest resources who will be made to suffer the most.

Always.
