As remote as they were beautiful, the coral reefs around the 5 volcano tips making up the Southern Line Islands dazzled National Geographic explorers in 2009 during a visit. Remarking that they re-painted the image of what a pristine coral reef looks like—bursting with color and life—the team of

Faster Ocean Warming Threatens Richest areas of Marine Biodiversity

The vulnerability of marine biodiversity to accelerated rates of climatic change is poorly understood. By developing a new method for identifying extreme oceanic warming events during Earth's most recent deglaciation, and comparing these to 21st century projections, we show that future rates of ocean warming will disproportionately affect the most speciose marine communities, potentially threatening biodiversity in more than 70% of current-day global hotspots of marine species richness.
