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,”...

X-Ray of the oceans

Using satellite data and spatial models, researchers estimate human influence in the ocean. Darker means more impact. Two-thirds of the ocean shows increased strain from human-related factors, such as fishing and climate change. And more than three-quarters of coastal waters suffer from climate change and increases in the effects of harmful land-based activities, including pollution. In all, the researchers classified more than 40 percent of the ocean as “heavily impacted”...
