Global warming not only increases ocean temperatures, it triggers a cascade of effects that are stripping the seas of oxygen. Fish are already moving to new waters in search of oxygen, and scientists are warning of the long-term threat to fish species and marine ecosystems.

ff the coast of southeastern China, one particular fish species is booming: the oddly named Bombay duck, a long, slim fish with a distinctive, gaping jaw and a texture like jelly. When research ships trawl the seafloor off that coast, they now catch upwards of 440 pounds of the gelatinous fish per hour — a more than tenfold increase over a decade ago. “It’s monstrous,” says University of British Columbia fisheries researcher Daniel Pauly of the explosion in numbers…

Microplastics Are Filling the Skies. Will They Affect the Climate? – Yale Environment 360

Micro Plastics in Arctic Snow (by Felton Davis CC BY 2.0 via Flickr).

Recent studies reveal that tiny pieces of plastic are constantly lofted into the atmosphere. These particles can travel thousands of miles and affect the formation of clouds, which means they have the potential to impact temperature, rainfall, and even climate change.

Plastic has become an obvious pollutant over recent decades, choking turtles and seabirds, clogging up our landfills and waterways. But in just the past few years, a less-obvious problem has emerged…
