Why Extreme Heat Is So Deadly

New CDC guidance encourages clinicians to start conversations with patients about dangerous heat

Scientists say extreme temperatures that reached 119 degrees Fahrenheit and killed at least 100 people in parts of West Africa would only occur every 200 years in the absence of climate change

The planet just saw the hottest span of 12 months in human history because of climate change driven by the burning of fossil fuels

The number of fatal heart attacks, strokes and arrhythmias could triple for older and Black adults as extreme heat increases with global warming

A heat dome that baked parts of South America in late September was made much more likely and at least 1.4 degrees Celsius (2.5 degrees Fahrenheit) hotter by climate change

With three degrees Celsius of warming, U.S. deaths during extreme temperatures could reach 63,000 a year, researchers calculate

Nearly every person on the planet saw high temperatures that were made at least twice as likely by climate change this summer

Extreme heat is becoming more common across the U.S. The federal government and employers owe workers better safety measures

August and September will bring tens of millions of public school students back to class. Many face health risks from rising temperatures

Soaring temperatures fueled by climate change are contributing to buckling highways, ruptured tires and impaired visibility from wildfire smoke

Extreme temperatures across the U.S. have put the elderly, outdoors workers and people with no access to cool air at the greatest risk of severe heat-related illnesses or even death

As extreme heat worsens, cities are exploring ways to reach isolated individuals before it’s too late

As summers get hotter and longer, experts provide advice on how to survive heat-related emergencies

From Phoenix, Ariz., to China to Spain, heat records are being set all over the world

Preliminary analyses show that this July is virtually certain to be the hottest month on record for the planet by a wide margin, largely because of global warming

Climate change made heat waves in the U.S. Southwest, Europe and China hotter and more likely

It’s not just the soaring temperatures of day that make heat waves dangerous. High nighttime temperatures add to the stress on human bodies

The Phoenix area has withered for a month under triple-digit temperatures that experts say will become more common with climate change

The temperature in Death Valley could rise above 130 degrees Fahrenheit this weekend. If it does, it would set a record for the hottest temperature ever reliably measured on Earth

Yet another heat dome will send temperatures skyrocketing across the U.S. Southwest just after the planet saw its hottest week on record

Tens of thousands of people died during intense heat waves in Europe last summer, indicating that heat prevention plans aren’t protecting vulnerable populations

When dangerous heat waves hit cities, better risk communication could save lives

From North America to South Asia, summer heat waves are becoming longer, stronger and more frequent with climate change.

New research says climate change was responsible for yet another withering heat wave, which baked South Asia in April
