An overload of carbon dioxide is acidifying seawater, posing a subtle but profound threat to marine invertebrates.

It’s not the extra few feet of water that make sea level rise so dangerous. It’s the extra few feet during a storm during El Niño during high tide, say researchers.

Emperor penguins can flourish in locales where few other animals roam. But scientists now wonder if they can adapt to a new threat: climate change.

Scripps Oceanography research suggests that climate change will require a complete rethinking of water delivery systems in the West. That'll be step one.

The inception of the "Keeling Curve," a history of atmospheric carbon dioxide levels, marked a key moment in American science history. The record began in March, 1958 at a small observatory on the top of Hawaii's Mauna Loa.

An ancient global warming episode drastically changed the planet. Life on Earth needed 200,000 years to recover. What we're headed for in the next century could be even bigger.

After two decades watching atmospheric oxygen levels drop, a Scripps researcher's conclusions about climate could leave one feeling light-headed
