HEAT

As we head into the dog days of summer, 2019 is projected to be among the top five hottest years on record. That's according to the National Oceanic and Atmospheric Administration.

In a mostly symbolic move, the U.S. House voted Thursday to stop the Trump administration from exiting the Paris Climate Agreement. Meanwhile, many cities and states in the Mountain West are continuing to warm faster than the national average.

A new study includes an interactive map that shows how your home will be affected by climate change in the next 50 years. No surprise —Idaho and the Mountain West will get hotter.

The sun is just a dim red dot. The nearby Canadian Rockies are shrouded in thick wildfire smoke.

Bob Gray knows we probably shouldn’t be hiking up a mountain right now.

“I have a scratchy throat,” he says. “Physically it effects my breathing. I probably shouldn’t spend a lot of time in it.”

Wildfire smoke reached dangerous levels across the Mountain West Monday. Eastern Washington had the worst air in the country and all 56 counties in Montana were under an air quality alert – possibly the first time that’s happened in the state’s history.

Over the last 30 years, the West has seen an uptick in the size and frequency of forest fires. Scientists have typically attributed the change to low snowpack and high summer temperatures. But researchers writing in the journal PNAS say the trend could have more to do with rain.

Utah officials are praising a Draper firefighter who was killed while battling California's biggest wildfire, the first fatality of the massive Mendocino Complex Fire. 

Scorching temperatures are hitting our region’s biggest tourist attractions. On Friday, temperatures at Glacier National Park hit triple digits for the first time in recorded history.

A couple days later, the Howe Ridge fire blew up.

Lodgers and campers awoke late Sunday night to officials telling them to get out as soon as possible.

A new study shows air pollution like soot, dust and smoke is down around the country with one exception: wildfire prone areas like the Mountain West.  

Record-breaking wildfires in California have prompted tweets from President Trump and U.S. Interior Secretary Ryan Zinke. They blame the fires on “bad environmental laws,” too many dead or dying trees, and not enough logging.

A Belgian hiker died from apparent heat-related causes earlier this week at the Utah-Arizona border.

A coalition of advocacy and labor groups have sent a petition to the Occupational Safety and Health Administration (OSHA). They’re calling for specific standards to protect construction, farm and other outdoor laborers from extreme heat. Right now there are no specific protections in place.  

Record-breaking temperatures are scorching the United States with parts of our region seeing all-time highs. A number of heat-related deaths are already being reported in the U.S.

There is a moment as heatstroke sets in when the body, no longer able to cool itself, stops sweating. Joey Azuela remembers it well.

"My body felt hot, like, in a different way," he says. "It was like a 'I'm cooking' hot."

Three summers ago, Azuela, then 14, and his father were hiking a trail in one of Phoenix's rugged desert preserves. It was not an unusually hot day for Phoenix, and they had gotten a later start than usual. By the time they reached the top, Azuela was weak and nauseous. They had run out of water.
