Largest Coral Atoll in the World Lost 80 Percent of Its Coral to Bleaching

Climate

The largest coral atoll in the world, Kiritimati, has lost 80 percent of its coral in the past 10 months due to this year’s devastating coral bleaching event and another 15 percent is likely to die, scientists reported.

The Pacific has been experiencing abnormally warm water temperatures for months, causing extreme stress to corals and the species that rely on them. This is the longest coral bleaching event ever recorded and scientists are becoming increasingly pessimistic that the affected reefs will recover.

Julia Baum from the University of Victoria described the atoll as a “horror show” and Kim Cobb of Georgia Tech called it “a wake-up call.”

In June, New York Times journalist Andy Newman wrote an article titled, "If seeing the world helps ruin it, should we stay home?" In it, he raised the question of whether or not travel by plane, boat, or car—all of which contribute to climate change, rising sea levels, and melting glaciers—might pose a moral challenge to the responsibility that each of us has to not exacerbate the already catastrophic consequences of climate change. The premise of Newman's piece rests on his assertion that traveling "somewhere far away… is the biggest single action a private citizen can take to worsen climate change."
