Dissolving the Future of Coral Reefs
Coral reefs, some of the planet’s most beautiful and biodiverse ecosystems, face many natural and anthropogenic threats. Tremendous effort has gone into protecting and rehabilitating these reefs worldwide, but the mounting problem of ocean acidification has the potential to obliterate all progress made by marine scientists, conservationists, and policy-makers thus far.

Photo Essay: Exploring the Rocks That Join the Americas
The formation of the slender land bridge that joins South America and North America was a pivotal event in earth’s history. At its narrowest along the isthmus of Panama, it changed not just the world map, but the circulation of oceans, the course of biologic evolution, and global climate. Cornelia Class, a geochemist at Columbia…
