Americans all over the country are facing record-breaking heat waves at the start of the summer, drawing attention to the disparities among heat-related deaths when it comes to Black people.

On Sunday, an excessive heat warning was issued by the National Weather Service for locations in the West and Pacific Northwest. The warning, which is the weather service’s highest alert, has affected about 36 million people, according to meteorologist Bryan Jackson.

The temperature reached 128 degrees at Death Valley National Park in eastern California on Sunday, causing one visitor to die and another to be hospitalized.

In New York City, extremely high temperatures continue throughout the month with temperatures expected to reach 90 for the fourth consecutive day. Authorities say residents should stay vigilant for any symptoms of heat stroke, such as hot and dry skin, increased heart rate, confusion and nausea.

Excessive temperatures have drawn attention to the disparities among heat-related deaths when it comes to Black people.

Heat is the top cause of weather-related deaths nationwide, killing around 350 New Yorkers each year, according to a city mortality report.

“Only a quarter of New York City’s population is African American, but half of the deaths from heat are African Americans, Bill Ulfelder, the executive director of the Nature Conservancy in New York, told AP. “So there is something wildly disproportionate.”
