From heat stress to sewage overflows, climate change promises to bring extreme weather that will challenge the ill-prepared U.S. public health infrastructure.
Extreme weather induced by climate change has dire public health consequences, as heat waves threaten the vulnerable, storm runoffoverwhelms city sewage systems and hotter summer days bake more pollution into asthma-inducing smog, scientists say.
The United States – to say nothing of the developed world – is unprepared for such conditions predicted by myriad climate models and already being seen today, warn climate researchers and public health officials.
“Climate change as it’s projected will impact almost every aspect of public health, both in the developed world and – more importantly – in the developing world,” said Michael McGeehin, director of the Environmental Hazards and Health Effects division at the Centers for Disease Control and Prevention.
“A flood is a major public health disaster,” he added. “A flood takes us back to the 1890s as far as the public health system is concerned.”
Last week, as the East Coast stewed its way through the first heat wave of the summer, researchers at Stanford University published a study suggesting exceptionally long heat waves and extreme temperatures could be commonplace in the United States within 30 years – sooner than expected.
“I did not expect to see anything this large within the next three decades,” Noah Diffenbaugh, assistant professor of environmental Earth system science at Stanford and lead author of the study, said in a statement. “It was definitely a surprise.”
The report was published in the journal Geophysical Research Letters.
Using some of the highest-resolution computer models to date, Diffenbaugh and Moetasim Ashfaq, a former Stanford postdoctoral researcher now at Oak Ridge National Laboratory, were able to simulate daily temperatures across small sections of the country.
They found an intense heat wave – equal to the longest on record from 1951 to 1999 – could hit western and central United States as many as five times between 2020 and 2029.
