White House climate adviser Gina McCarthy called heat stress a “silent killer” that disproportionately affects the poor, elderly and minority groups. While not as dramatic as wildfires or hurricanes, “heat stress is a significant, real threat that has deadly consequences,″ McCarthy said in an interview.
“Many people don’t recognize that heat stress is a real physical problem until it’s too late for them,″ she said.
A June heat wave in the Pacific Northwest, exacerbated by climate change, caused hundreds of deaths and thousands of emergency room visits for heat-related illnesses, In Louisiana, more than a million people, including the entire city of New Orleans, lost power when Hurricane Ida struck on Aug. 29. At least 12 of the 28 Ida-related deaths in Louisiana were caused by heat, according to the Louisiana Health Department.
"Rising temperatures pose an imminent threat to millions of American workers exposed to the elements, to kids in schools without air conditioning, to seniors in nursing homes without cooling resources, and particularly to disadvantaged communities,'' Biden said, citing National Weather Service data that extreme heat is now the leading weather-related killer in America.
Labor’s Occupational Safety and Health Administration, or OSHA, is set to issue a new rule on heat illness prevention in outdoor and indoor work settings and will focus interventions and workplace inspections on days when the heat index exceeds 80° F (26.7 degrees Celsius). The White House called the rule a significant step toward a federal heat standard in U.S. workplaces and said officials will expand the scope of scheduled and unscheduled inspections to address heat-related hazards.
The administration also will expand its Low Income Home Energy Assistance Program, or LIHEAP, to boost programs to address extreme heat, the White House said. The program traditionally focuses on providing heat during winter weather, but will be expanded to help with purchasing air conditioning units or paying electric bills for cooling assistance.
The administration also is expanding the use of schools and other public buildings as cooling centers, a program McCarthy called life-saving. "They are opportunities for people in every community to actually find relief at a time when they need it most,'' she said.
McCarthy urged communities to implement programs such as “adopt a senior citizen” to conduct wellness checks, making sure that elderly residents are drinking fluids and not overheating. “That kind of personal touch is going to be the difference between an individual living longer and those that are passing away, basically unrecognized in their own homes,″ she said.
David Hondula, an associate professor Arizona State University's Urban Climate Research Center, said heat-related deaths are underreported nationwide and frequently occur in isolation, to "people who are literally alone.'' He applauded the Biden initiative, but said more data is needed about health risks posed by extreme heat.
“Better tracking of heat-health impacts across the country can help us make smart investments,” Hondula said. More frequent inspections and safety checks at work sites — especially in agriculture and construction — will save lives, he said, adding that a proposed workplace heat standard "could be quite consequential for how work happens in the United States.''
The Biden administration has taken steps since its first days in office to tackle climate change. Extreme weather events across the country — from wildfires in California, to Hurricane Ida and related floods that killed scores of people from Louisiana to New York — "have blown apart the lives of working families, wiping homes and businesses off the map,'' Biden said.
“This is a blinking code red for our nation,'' he added. "We cannot wait to act to meet the broader crisis of climate change.''
As part of the new effort, the administration is focusing on urban “heat islands” where temperatures in cities with fewer trees and higher pavement concentrations can be higher than in surrounding areas. The administration will expand urban forestry programs and other “greening” projects to reduce extreme temperatures and heat exposure, the White House said.
The Department of Homeland Security, meanwhile, is launching a series of prize competitions focused on strengthening the nation’s resilience to climate change. The first competition will focus on new ways to protect people at risk of heat-related illness or death during extreme heat events or in connection with other disasters.
Public Citizen, a watchdog and consumer advocacy group, said federal action on heat stress is long overdue. The proposed workplace heat standard is especially important, the group said, noting that “Black and Brown communities, especially farmworkers, are disproportionately subjected to work in extreme heat resulting in more heat stress illnesses, injuries and death.″
