Conserving Coral Reefs

The world’s ocean is facing dire threats — and coral reef ecosystems are on the frontlines. Unrestrained tourism, declining water quality, and overfishing continue to endanger coral ecosystems but climate change has become their biggest threat. Even with drastic emission reductions, most of the world’s corals could still vanish by mid-century. But there’s hope: climate resilient corals have been found around the world. Reducing emissions in line with the Paris Agreement, and managing local pressures on resilient reefs, allows these reefs to thrive and replenish neighboring reefs – ensuring the long-term survival of our world’s coral reefs.

Coral reef ecosystems around the globe are likely to disappear by 2050 if the goals of the Paris Agreement are not met.

Even with drastic emission reductions to ensure we keep warming within 1.5ºC above pre-industrial levels, 70-90% of the world’s corals could still vanish by mid-century, leaving only remnants of the reefs we see today.

About Bloomberg Ocean Initiative Coral Reef Conservation

In 2018, the 50 Reefs study, a key pillar of our coral reef conservation program, identified a global portfolio of the world’s coral reefs that are the most likely to survive climate change. Managing local pressures, like water pollution and overfishing, on these reefs is critical to their survival. The Bloomberg Ocean Initiative uses the science of the 50 Reefs study to guide our approach to protecting coral reefs, working with partners Rare, the Wildlife Conservation Society (WCS), and others to advance on-the-ground conservation projects to protect these climate resilient coral reefs.
