Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration.

Americans are leaving many of the U.S. counties hit hardest by hurricanes and heatwaves—and moving towards dangerous wildfires and warmer temperatures, says one of the largest studies of U.S. migration and natural disasters. These results are concerning, as wildfire and rising temperatures are projected to worsen with climate change. The study was inspired by the increasing number of headlines of record-breaking natural disasters.

Heat-related deaths occur across Washington state, even in regions with typically milder climates. This is the most extensive study yet of heat-related mortality in Washington state, and the first to look beyond the major population to and include rural areas. Researchers used statistical methods to uncover “hidden” deaths that may have listed something else, like illness or a chronic disease, as the primary cause.

Summertime means lots of opportunities for fun in the sun. But this year’s high temperatures also bring an increased risk of dehydration that can cause urinary tract infections (UTIs), said Maude Carmel, M.D., Associate Professor of Urology at UT Southwestern Medical Center. These common infections are marked by a burning sensation or pain with urination, increased urinary frequency, urinary urgency, and blood in the urine (a condition called hematuria).

By: Bill Wellock | Published: July 13, 2022 | 3:50 pm | SHARE: Extreme heat is the leading weather-related cause of death in the United States. It can kill through heat exhaustion or heat stroke, as well as by contributing to deaths from heart attacks, stroke, kidney failure and other diseases. Vulnerable populations, such as older adults, infants, outdoor workers and others, are at increased risk.
