A new study analyzed temperature and mortality data over 13 years for 15 U.S. cities and incorporated computer modeling to simulate various types of heat-related scenarios.
Houston and Dallas are two of the 15 cities studied in this analysis. Other cities include Atlanta, Boston, Chicago, Detroit, Los Angeles, Miami, New York, Philadelphia, Phoenix, San Francisco, Seattle, St. Louis, and Washington DC.
In addition to the U.S., heat-related mortality caused by climate change is projected to significantly impact Europe, the Americas, East and Southeast Asia, Australia, the Middle East, and North Africa.
“As global temperatures rise, we expect, and indeed have already seen, an increase in intensity and frequency of extreme heat waves,” says Dr. Eunice Lo, research associate at Bristol Research Initiative for the Dynamic Global Environment (BRIDGE) at the University of Bristol, and the study’s lead author. “Extremely high temperatures that persist prevent our body from maintaining its core temperature; this can lead to health conditions like heat stroke, which can be fatal.”
“The vulnerability of a location to heat depends on its preparedness to heat, peoples’ accessibility to health care and air conditioning, its population structure, et cetera,” Lo explains. “The elderly, young children and poorer households are more vulnerable to heat stress, for example.”
