As climate change alters water colors, deep-sea divers in the Dominican Republic (one shown) use the shifting colors to gauge conditions. Colors such as yellow and green, shown here, mean that divers can’t see the seafloor from the surface, so they must dive down more frequently — an exhausting process.
