The Nets That Need Fixing
Spent last week in Muskegon watching Joel Petersen run the same calculation on his phone for the third year: repair costs versus what he might catch, minus fuel and dock fees and property taxes. The nets are spread across his garage floor, torn up, and the math never works. His family's fished Lake Michigan whitefish for four generations. Scientists say maybe ten years left before they're gone. But Joel's real timeline is his 73-year-old dad—however long Alan wants to keep going out is probably how long the Petersen operation lasts.
What's sticking with me is how fast the lake changed. Waters warming, winter ice way down, invasive mussels filtering everything clean so baby whitefish can't survive. Joel catches fish in their twenties, almost no young ones coming up. He knows what it means. And he's still probably fixing those nets before spring, not because he thinks it'll turn around but because the alternative is deciding it's over and he's not ready to be the generation that makes that call.

What It Means Here
Heat killed 546,000 people globally last year, according to the 2025 Lancet Countdown released this week by 128 health researchers. That's a 23% increase in heat mortality since the 1990s. The average person experienced 16 additional days of dangerous heat in 2024 that wouldn't have existed without climate change.
The numbers land differently depending on where you live and how old you are. Infants and adults over 65 faced more than 20 heatwave days each last year, four times what they experienced two decades ago. Heat exposure cost 640 billion potential labor hours globally, translating to $1.09 trillion in lost wages and productivity.
What this means for your specific situation depends on your age, geography, whether you work outdoors, and what health conditions you're managing. The research provides a framework for understanding your exposure, not instructions for what to do about it.
