Clark County has been feeling the heat, but not all neighborhoods are sweating it out equally, according to a recent study. Findings from a "Heat Watch" event, conducted last summer by Clark County Public Health and a troop of over 50 volunteers, revealed stark disparities in temperature readings across various regions of the county. As reported by Clark County, Washington, areas thick with buildings and concrete were notably hotter, particularly in the afternoon, with temperature differences reaching up to nearly 10 degrees in the evening based on location.
Amy Koski, the built environment coordinator at Clark County Public Health, pointed out the implications of these findings. "People who live in historically disinvested neighborhoods, who have limited access to resources like air conditioning and green space, and those with other health issues are all at greater risk for impacts from extreme heat," she said in a statement. Volunteers, equipped with special gear, drove around the county capturing more than 102,000 temperature readings, shedding light on the urban heat islands and cooler spots with more greenery.
When looking at the data, one afternoon, the hottest spots included the Vancouver area, touching downtown, Orchards, Fourth Plain, and Fruit Valley. Evening heat clung to Washougal and parts of Vancouver like a bad suit, particularly in neighborhoods such as Ogden, Bennington, and Fisher’s Landing East. Yet, places like Ridgefield and the western parts of Camas enjoyed lower temperatures, thanks in part to their natural spaces and trails.
These discrepancies aren't just numbers on a thermometer; they translate to real health risks. Extreme heat, flagged as the deadliest weather-related hazard in the United States, has a knack for sending people, especially those in vulnerable groups, to emergency departments when the mercury spikes. The health impacts, amplified in urban heat islands, span from heart and breathing complications to mental health issues, as laid out in the Public Health's findings shared with the Clark County Board of Health on Wednesday.
Signing up for public alerts, monitoring weather and heat risk forecasts, along with community-level preparedness, offers some defense against the onslaught of heat waves. Clark County Public Health encourages people to look out for their neighbors, particularly the most at-risk, to mitigate the toll of extreme weather.
