Coral Reefs Disappearing Twice As Fast As Rainforests

Corals in the central and western Pacific Ocean are dying faster than previously thought. University of North Carolina at Chapel Hill researchers have found nearly 600 square miles of reef have disappeared per year since the late 1960s, twice the rate of rainforest loss. The reefs are now disappearing at a rate of one percent per year, a decline that began decades earlier than expected. Historically, coral cover, a measure of reef health, hovered around 50 percent. Today, only about 2 percent of reefs in the Indo-Pacific have coral cover close to the historical baseline. “We have already lost half of the world’s reef-building corals,” said John Bruno, author of the study published in the online journal PLoS One. The Indo-Pacific contains 75 percent of the world’s coral reefs and has the highest coral diversity in the world.

One of the most surprising results of the study was that coral cover was similar between reefs maintained by conservationists and unprotected reefs. This consistent pattern of decline across the entire Indo-Pacific indicates that coral loss is a global phenomenon, likely due in part to large-scale stressors such as climate change. . .

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
