Increasing ocean temperatures, decreasing ice

For National Geographic, Kennedy Elliot made a series of heatmaps that show the relative shifts in the ocean:

The oceans don’t just soak up excess heat from the atmosphere; they also absorb excess carbon dioxide, which is changing the chemistry of seawater, making it more acidic. “Ocean acidification is one simple and inescapable consequence of rising atmospheric CO2 that is both predictable and impossible to attribute to any other cause,” says oceanographer John Dore of Montana State University.

Great.
