The medical dangers of heat are real. But people often ignore public heat alerts, or don't know how vulnerable they are. A new alert system prompts clinicians to talk about heat with patients.
Like other places, New Orleans has seen record numbers of people falling ill with heat-related conditions. First responders and hospitals race to respond with ice, fluids, and air conditioning.
El Niño is warming up the water in the Pacific Ocean. That extra heat affects the whole planet, and has helped drive record-breaking hot weather.
"If it's hot outside for you, it's most likely even hotter for your pet," one expert tells NPR. Here's how to protect your pet outdoors, keep them engaged inside and respond to signs of heat stroke.

The connection between weather and climate change has never been clearer. And simultaneous extremes, such as hot and dry weather together, are particularly dangerous.
Scientists and forecasters are trying to figure out how to talk about the connection between climate change and severe weather. It could have big impacts on how people think about global warming.
Unprecedented heat waves are on the rise as the climate gets hotter. But experts say the country's heat warning system may be leading the public to underestimate the dangers.

For decades, it was impossible to say that a specific weather event was caused, or even made worse, by climate change. But advanced research methods are changing that.
Many of this year's deadly extreme weather is linked to climate change and scientists warn they're a sign of what's to come.
