Climate Change Isn’t Just a 21st Century Problem

Humans have been burning fossil fuels for only about 150 years, yet that has started a cascade of changes that will still be felt 10,000 years from now.

What Is Ocean Acidification & Why Does It Matter?

As excess carbon dioxide is absorbed into the oceans, it is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain.

The Southern Ocean Is Breathing in Carbon Dioxide at a Healthy Rate

Since the late 1980s, the Southern Ocean’s rate of CO2 uptake appeared to have stagnated, alarming scientists. New data shows a recovery.

Global Warming’s ‘Missing’ Heat: It May Be in the Indian Ocean

A team of oceanographers says much of the heat trapped in the atmosphere by greenhouse gases is being soaked up and stored by the oceans–at least for now.

In northern winter, the Bering Sea, dividing Alaska and Siberia, becomes the most acidic region on earth (in purple) as shown in this February 2005 acidity map in pH scale. Temperate oceans are less acidic. The equatorial Pacific is left blank due to its high variability around El Niño and La Niña events. (Takahashi)
