When wildfires rage, the immediate threat is obvious – but smoke from the fires actually kills far more people than the flames. As fires become more frequent, that smoke is leading to a public health crisis. In a new study published in the journal Science Advances, we found that wildfire smoke likely contributed to more than 52,000 premature deaths across California alone from 2008 to 2018, with an economic impact from the deaths of more than US$430 billion. Previous studies have examined the short-term health risks from wildfire smoke, but few have assessed how exposure to wildfire smoke over years adds up to shorten human lives. Smoke from far-off wildfires turns the skies orange over San Francisco in 2020. Running in wildfire smoke carries harmful particles deep into a person’s lungs.

Fatal attractions are a standard movie plotline, but they also occur in nature, with much more serious consequences. As a conservation biologist, I’ve seen them play out in some of Earth’s most remote locations, from the Gobi Desert to the Himalayan Highlands. In these locales, pastoralist communities graze camels, yaks and other livestock across wide ranges of land. The problem is that often these animals’ wild relatives live nearby, and huge, testosterone-driven wild males may try to mate with domestic or tamed relatives. Both animals and people lose in these encounters. Herders who try to protect their domestic stock risk injuries, emotional trauma, economic loss and sometimes death. Wild intruders can be displaced, harassed or killed. These clashes threaten iconic and endangered species, including Tibetan wild yaks, wild two-humped camels and Asia’s forest elephants. If the wild species are protected, herders may be forbidden from chasing or harmin...

Coast to coast, millions of Americans are experiencing sweltering temperatures this summer, with seemingly little relief in sight. For people who struggle to access or afford air conditioning, the rising need for cooling is a growing crisis. An alarming number of Americans risk losing access to utility services because they can’t pay their bills. Energy utility providers in 2022 shut off electricity to at least 3 million customers who had missed a bill payment. Over 30% of these disconnections happened in the three summer months, during a year that was among the hottest on record. In some cases, the loss of service lasted for just a few hours. But in others, people went without electricity for days or weeks while scrambling to find enough money to restore service, often only to face disconnection again. As researchers who study energy justice and energy insecurity, we believe the United States is in the midst of a disconnection crisis. We started tracking these disconnect...

Federal Chevron deference is dead. On June 28, 2024, in a 6-3 vote, the Supreme Court overturned the 40-year-old legal tenet that when a federal statute is silent or ambiguous about a particular regulatory issue, courts should defer to the implementing agency’s reasonable interpretation of the law. The reversal came in a ruling on two fishery regulation cases, Loper Bright Enterprises v. Raimondo and Relentless, Inc. v. Department of Commerce. This decision means that federal courts will have the final say on what an ambiguous federal statute means. What’s not clear is whether most courts will still listen to expert federal agencies in determining which interpretations make the most sense. While courts and judges will vary, as a scholar in environmental law, I expect that the demise of Chevron deference will make it easier for federal judges to focus on the exact meaning of Congress’ individual words, rather than on Congress’ goals or the real-life wor...

Hurricane Beryl was the latest Atlantic storm to rapidly intensify, growing quickly from a tropical storm into the strongest June hurricane on record in the Atlantic. It hit the Grenadine Islands with 150 mph winds and a destructive storm surge on July 1, 2024, then continued to intensify into the basin’s earliest Category 5 storm on record. Beryl was still a powerful Category 4 hurricane on July 3 when its eyewall brushed the coast of Jamaica and headed toward the Cayman Islands. A large part of Mexico’s Yucatan Peninsula was under a hurricane warning. The damage Beryl caused, particularly on Carriacou and Petite Martinique, was extensive, Grenada Prime Minister Dickon Mitchell told a news briefing. “In half an hour, Carriacou was flattened.” Beryl’s strength and rapid intensification were unusual for a storm so early in the season. This year, that is especially alarming as forecasters expect an exceptionally active Atlantic hurricane season....
