Increasing ocean temperatures have caused populations of many fish and shellfish to plummet. As a result, the amount that can be caught without depleting fish populations has declined by an average of 4.1 percent worldwide.

This painted sign, by Xavier Cortada, is a marker that someone can plant in their yard. It shows how high the sea would have to rise to flood the owner’s home (5 feet, or 1.5 meters).

Cameras set up in the Arctic’s Chukchi and Bering seas (one shown) record the amount of light that reaches water through the ice. More light means more algal blooms.

Being stressed or afraid may alter a person’s usual scent. That can throw dogs off the person’s track. People with a particular version of a gene may have a bigger change in odor when stressed, data show.
