Planet’s darkening oceans pose threat to marine life, scientists say. Band of water where marine life can survive has reduced in more than a fifth of global ocean between 2003 and 2022.

Girl, no! The albedo!

The oceans darken when light finds it harder to penetrate the water. It is often seen along coastlines where upwellings of cold, nutrient rich water rise to the surface, and where rainfall sweeps nutrients and sediments from the land into the water.

The drivers for darkening far offshore are less clear

Surely it's from increasing land erosion due to heavy rain and agricultural practices causing more sediments to be swept into the ocean? There's dead zones around the mouths of all our rivers because they're so full of nutrient and there are thousands year floods hitting every year. Like???
