Oceans Could Soon Not Have Enough Oxygen To Support Marine Life (iflscience.com)

An anonymous reader writes: As the climate continues to change in response to the increasing amount of carbon humans pump into the atmosphere, the oceans are being particularly hard hit from melting Arctic sea ice, acidification, and warming surface temperatures. Yet those are not the only difficulties that marine life has to deal with, as a new study reports that the oceans are also losing oxygen. As the majority of marine life relies on the oxygen dissolved in the oceans, it is worrying that noticeable differences have been observed in the gas concentrations in the world's waters. The reduction in oxygen will have profound effects on ocean biodiversity, though as the study published in Global Biogeochemical Cycles shows, not all regions will be affected in the same way or over the same period of time."Loss of oxygen in the ocean is one of the serious side effects of a warming atmosphere, and a major threat to marine life," said lead author Matthew Long of the National Center for Atmospheric Research. "Since oxygen concentrations in the ocean naturally vary depending on variations in winds and temperature at the surface, it's been challenging to attribute any deoxygenation to climate change. This new study tells us when we can expect the impact from climate change to overwhelm the natural variability."

I propose the installation of a giant aquarium bubbler at the bottom of the ocean.

the treasure chest that opens to release a torrent of built up bubbles is a classic, but i've always been partial to the skeleton at the helm with his head bobbing in the air stream.

How about getting Trump and a couple of other politicians to blow into that straw? Only problem might be raising the ocean temperature with all of that hot air.

I just want to see how big the plastic treasure chest is that lets that many bubbles out!

Yikes

I wouldn't want to be a dolphin right now.

I just got this package delivered fedex...

It's a kind of vase thingy with the words 'So long, and thanks for all the fish.' etched into it.

Really pretty, but I think it means that the dolphins are going to be OK.
