Hawaii's knobby finger coral careened toward extinction in 2015. The species was so rare that scientists could only find a few fragments in the wild, scattered across the seabed of Oahu's Kaneohe Bay.
It might have been a familiar story. Vanishing species like Southern Resident orcas and North Atlantic right whales pile up in the news. Outlooks are especially bleak for corals. Rising ocean temperatures cause bleaching, which has killed 30 to 40 percent of reefs worldwide in recent years. But the knobby finger coral's story didn't go that way, thanks to computer forecasting: science's crystal ball.
