Two years in the past, an unprecedented warmth occasion slammed the Pacific Northwest, setting 128 all-time excessive temperature data and killing 441 individuals between June 27 and July 3. It overwhelmed our medical methods and precipitated untold struggling, significantly for individuals who are aged, pregnant, have continual ailments, residing with psychological well being and substance abuse points, work outside and communities of colour.
This expertise was distinctive for us however completely in line with that of many different cities which have skilled excessive warmth in recent times. We all know warmth is harmful, significantly in areas with extra paved surfaces and fewer vegetation. Air con is strongly protecting, however not widespread right here, and its set up and operation is dear. The poor reside in hotter locations, in poorly insulated and cooled buildings, with fewer assets to guard themselves.
Now, in 2023, an El Niño is bringing unusually heat and dry situations. We’ve already skilled excessive warmth days this Might and June, and an unusually lengthy dry stretch for this time of 12 months. Local weather fashions venture even worse to come back — Washington will expertise between 17 and 30 excessive warmth days per 12 months by the 2050s, 5 occasions our historic common. We clearly want to arrange for excessive warmth going ahead. If we don’t take the teachings of 2021 to coronary heart, the implications shall be predictable and devastating. We’ve been warned.
Whereas excessive warmth could also be new to us, it’s hardly new below the solar. We will, and will, quickly construct on different communities’ expertise to scale back well being dangers. Concerted motion has had dramatic results in different cities. In a brand new report (at st.news/hot), we describe quite a few potential options, many derived from fascinated with long-term threat discount, not simply emergency response.
For instance, whereas we reside within the Emerald Metropolis, our greenery is just not equitably distributed, and we’re shedding it quick. The inequity is a legacy of historic environmental racism and redlining. Planting timber and constructing shade buildings the place individuals are most uncovered, together with bus stops and parks, might present aid from the warmth and supply different well being advantages. Equally, planting rooftops with vegetation or portray them white in order that they mirror warmth can cut back city warmth islands. Used broadly, these methods considerably blunt the warmth island impact.
Equally, there are low-cost, accessible, and sustainable methods to remain cool and maintain one another secure when the climate is dangerously sizzling, however we’ve got to get the phrase out. We have to work with trusted neighborhood messengers to design and ship culturally nuanced warmth consciousness campaigns. Right here, too, we’ve got examples: New York Metropolis developed a door-to-door wellness examine program the place neighborhood volunteers examine on at-risk residents. Baltimore developed greater than a dozen “resiliency hubs” in church buildings and nonprofits, offering water, cooling and machine charging. Seattle might simply replicate each initiatives and implement others outlined in our report.
Defending individuals from warmth requires participation of many teams and establishments not tasked with defending public well being, like municipal planning departments, church buildings, parks and recreation departments, community-based nongovernmental staff, employers of outside staff, and lots of state companies past the Division of Well being. Some cities, together with Phoenix, have created warmth workplaces to coordinate throughout companies, ranges of presidency, and a number of sectors. Such modern concepts needs to be significantly thought of regionally.
The local weather will proceed to alter, and Seattle will proceed to develop. We will do a a lot better job defending those that are most susceptible to excessive warmth. We all know what to do. We simply must mobilize the assets and decide to taking the actions confirmed to avoid wasting lives.
