This simulation allows students to explore the change in sea surface pH levels with increasing CO2 levels.

This short video is an excerpt from the longer video Acid Test: The Global Challenge of Ocean Acidification, produced by the National Resources Defense Council (NRDC). This short version summarizes the science of ocean acidification as well as the social implications.

This interactive visualization depicts sea surface temperatures (SST) and SST anomalies from 1885 to 2007. Learn all about SST and why SST data are highly valuable to ocean and atmospheric scientists. Understand the difference between what actual SST readings can reveal about local weather conditions and how variations from normalâcalled anomaliesâcan help scientists identify warming and cooling trends and make predictions about the effects of global climate change. Discover the relationships between SST and marine life, sea ice formation, local and global weather events, and sea level.

You're not the only one wondering if we will see El Niño grow or continue into this coming winter 2015.  How useful are March winds and subsurface temperatures across the tropical Pacific Ocean in predicting winter El Niño or La Niña states?

Guest blogger Dennis Hartmann makes the case that warm waters in the western tropical Pacific—part of the North Pacific Mode climate pattern—are behind the weird U.S. winter weather of the past two seasons.

At the beginning of February, the atmosphere was looking a little bit like El Niño. Is this just another rolling stone?

The tropical Pacific Ocean sloshes around like water in your bathtub.  These waves are as important as the vortex of water that spirals down the drain.

What's behind the drop in probabilities this month? And why might forecasting this event be particularly tricky?

How El Niño is like different flavors of ice cream.  Seriously.

As of late August 2014, tropical atmospheric temperatures appear to be responding more strongly to the ocean than they typically do at this early stage of El Niño development.
