FRISCO — Warming ocean temperatures will have a cascading effect reaching even the deepest parts of the ocean, researchers with the UK’s National Oceanography Centre warned in a new paper published in the scientific journal Global Change Biology.

Their study quantifies future losses in deep-sea marine life, finding that marine life on the ocean floor will decline by up to 38 percent in the North Atlantic and by more than 5 per cent globally during the next century.

These changes will be driven by a reduction in the plants and animals that live at the surface of the oceans that feed deep-sea communities. As a result, ecosystem services such as fishing will be threatened. Continue reading
