Heat domes and extreme heat waves have been battering the United States for years now, and a new study shows that increasing temperatures are doing real harm to humans.
has occurred during the past two decades among patients treated at U.S. Department of Veteran Affairs health facilities, VA researchers have found.
VA diagnoses for heat illness nationwide increased from about 24 cases per 100,000 patients in 2002 up to 35 cases per 100,000 in 2019, according to results published in the July-August issue of theThis was a “statistically significant and clinically important increase,” the researchers said, adding that people with multiple chronic illnesses were most at risk.
“Some typically warmer U.S. states, including areas like New Mexico and Nevada and Louisiana, actually did not have a dramatic increase in heat-related illnesses, where others did,” Osborne said. Osborne and his colleagues think this shows that some hotter states are better prepared for climate change, because they've already been dealing with heat waves.

When water temperature goes over a seasonal threshold for five days or more, that's a marine heat wave. They do their worst damage in summer, when the ocean is already at its warmest, but they can occur any time of year.

How short-term heat waves impact apex marine predatorsA large team of marine scientists affiliated with a host of institutions across the U.S. has learned how some marine apex predators react to short-term heat waves. In their study, published in the journal Nature Communications, the group analyzed tag data from ocean species, including sharks and whales, to learn more about their behavior during these heat waves.
