Arizona Attorney General Kris Mayes sued the owners of three Tucson rental properties accused of leaving tenants without central air conditioning under extreme summer heat.

Extreme heat is one of the top five extreme weather hazards in Missoula County, and across the county the increase in the number of annual days above 90 degrees is a trend that is expected to continue as a result of climate change.

Climate Smart Missoula and its local partners this week launched a first-of-its-kind heat index and temperature map for Missoula County, revealing heat islands and their potential threat to public health.

Temperatures in Maryvale, one of Phoenix’s most underserved neighborhoods, often rise six degrees higher than other areas of the city, exacerbated by the urban heat island effect and the lack of trees and foliage compared to wealthier neighborhoods.

After a surge of heat-related deaths in Nevada, state lawmakers are proposing a bill that would require the nation’s two fastest-warming cities to actively protect residents from extreme heat.

The Missoula study also found that some of the highest rates of emergency calls during extreme heat events came from rural areas, outside Missoula’s urban core.

Earth saw a record-high average daily temperature of 62.87 degrees Fahrenheit on Monday, the EU climate monitor said, breaking the previous record of 62.76 degrees Fahrenheit set just the day before.

Despite Nevada having two of the fastest warming cities in the nation — Reno and Las Vegas — the state has taken the least action to protect the public from the impacts of climate change.

With an average monthlong temperature of 102.7 degrees Fahrenheit, the capital of Arizona made history in July.

The Earth experienced the hottest June in at least 174 years of record keeping, according to a report released Thursday by the National Oceanic and Atmospheric Administration.
