DATA: HIGH TEMPS A THREAT TO HOMELESS
Hundreds of people without shelter die from heat each year
Hundreds of blue, green and gray tents are pitched under the sun’s searing rays in downtown Phoenix, a jumble of flimsy canvas and plastic along dusty sidewalks. Here, in the hottest big city in America, thousands of homeless people swelter as the summer’s triple-digit temperatures arrive.
The stifling tent city has ballooned amid pandemicera evictions and surging rents that have dumped hundreds more people onto the sizzling streets that grow eerily quiet when temperatures peak in the midafternoon. A heat wave earlier this month brought temperatures of up to 114 degrees — and it’s only June. Highs reached 118 degrees last year.
“During the summer, it’s pretty hard to find a place at night that’s cool enough to sleep without the police running you off,” said Chris Medlock, a homeless Phoenix man known on the streets as “T-Bone” who carries everything he owns in a small backpack and often beds down in a park or a nearby desert preserve to avoid the crowds.
“If a kind soul could just offer a place on their couch indoors maybe more people would live,” Medlock said at a dining room where homeless people can get some shade and a free meal.
Excessive heat causes more weather-related deaths in the United States than hurricanes, flooding and tornadoes combined.
Around the country, heat contributes to some 1,500 deaths annually, and advocates
estimate about half of those people are homeless.
Temperatures are rising nearly everywhere because of global warming, combining with brutal drought in some places to create more intense, frequent and longer heat waves. The past few summers have been some of the hottest on record.
Just in the county that includes Phoenix, at least 130 homeless people were among the 339 individuals who died
from heat-associated causes in 2021.
“If 130 homeless people were dying in any other way it would be considered a mass casualty event,” said Kristie L. Ebi, a professor of global health at the University of Washington.
It’s a problem that stretches across the United States, and now, with rising global temperatures, heat is no longer a danger just in places like Phoenix.
This summer will likely bring above-normal temperatures over most land areas worldwide, according to a seasonal map that volunteer climatologists created for the International Research Institute at Columbia University.
Last summer, a heat wave blasted the normally temperate U.S. Northwest and had Seattle residents sleeping in their yards and on roofs, or fleeing to hotels with air conditioning. Across the state, several people presumed to be homeless died outdoors, including a man slumped behind a gas station.
In Oregon, officials opened 24-hour cooling centers for the first time. Volunteer teams fanned out with water and ice pops to homeless encampments on Portland’s outskirts.
A quick scientific analysis concluded last year’s Pacific Northwest heat wave was virtually impossible without human-caused climate change adding several degrees and toppling previous records.
Even Boston is exploring ways to protect diverse neighborhoods like its Chinatown, where population density and few shade trees help drive temperatures up to 106 degrees some summer days. The city plans strategies like increasing tree canopy and other kinds of shade, using cooler materials for roofs, and expanding its network of cooling centers during heat waves.
It’s not just a U.S. problem. An Associated Press analysis last year of a dataset published by Columbia University’s climate school found exposure to extreme heat has tripled and now affects about a quarter of the world’s population.
This spring, an extreme heat wave gripped much of Pakistan and India, where homelessness is widespread because of discrimination and insufficient housing. The high in Jacobabad, Pakistan, near the border with India hit 122 degrees in May.
Climate scientist David Hondula, who heads Phoenix’s new office for heat mitigation, says that with such extreme weather now seen around the world, more solutions are needed to protect the vulnerable, especially homeless people who are about 200 times more likely than sheltered individuals to die from heat-associated causes.
“As temperatures continue to rise across the U.S. and the world, cities like Seattle, Minneapolis, New York or Kansas City that don’t have the experience or infrastructure for dealing with heat have to adjust as well.”
