I visited a beautiful coral reef in 2022. What I saw there this summer shocked me.

“Coral in the Florida Keys, home to the largest reef in the continental US, is dying. The ghostly white appearance of the coral above is due to a phenomenon known as bleaching. Coral, an anemone-like marine animal, gets most of its color and food from a kind of algae that lives within its tissue. When that algae disappears, the coral appears stark white. Bleached corals aren’t dead; they are starving to death.

What happened between those two snapshots is extreme and unrelenting heat. Since July, a record-setting heat wave has been cooking waters in Florida and parts of the Caribbean, at times pushing water temperatures above 100 degrees. This excessive heat causes the relationship between coral and those symbiotic algae to break down; the algae leave the coral, though it’s not entirely clear which initiates the breakup.

The result of this epic marine heat wave is a devastating bleaching event that stretches across the Keys and much of the Caribbean, threatening the future of the region’s coral reefs. That in turn threatens human lives and well-being. These ecosystems — which were already under siege well before this summer — protect coastal communities from storm surge, support fisheries, and drive tourism.”

“Underwater photojournalist Jennifer Adler and I went scuba-diving in the Florida Keys before and after this marine heat wave. What we saw is a stark reminder that climate change is not a distant threat; it’s destroying ecosystems today.”

This summer is giving us a glimpse at the dangerous future of work

“Temperatures also don’t have to be very high for strenuous work to become deadly. The lack of heat acclimatization all too frequently kills workers; the majority of workers who die from heat do so in the first few days at work. “A lot of workers will actually end up in heatstroke during the first week on the job,” says Brenda Jacklitsch, a health scientist at the National Institute for Occupational Safety and Health (NIOSH).
Extreme heat is also affecting productivity. According to a 2022 study by The Lancet, which is tracking the relationship between climate change and public health, about 470 billion hours of labor were lost in 2021 due to extreme heat. The US alone lost 2.5 billion hours, mostly in the construction, manufacturing, service, and agriculture sectors.”

Experts say Covid-19 cases are likely about to surge

“The surge of Covid-19 cases and deaths in America over the summer resulted from a toxic mix of factors: states reopening, lockdown fatigue, and a season typically filled with vacations and holidays like Memorial Day and the Fourth of July. People gathered and celebrated indoors — at bars, restaurants, and friends and family’s homes. Millions of people got sick, and tens of thousands died.

This fall, experts worry it will all happen again: States are rolling back restrictions, people are eager to get back to normal, and Thanksgiving and Christmas are coming up. America may be on the verge of repeating the same mistakes, which would risk yet another surge in the Covid-19 epidemic.”
