By combining oxygen loss with ever-worsening ocean warming and acidification, humans are re-creating the conditions that led to the worst-ever extinction, which killed over 90 percent of marine life 252 million years ago.
This scares me more than arctic methane.
Depletion of dissolved oxygen in our oceans, which can cause dead zones, is occurring much faster than expected, a new study finds.
And by combining oxygen loss with ever-worsening ocean warming and acidification, humans are re-creating the conditions that led to the worst-ever extinction, which killed over 90 percent of marine life 252 million years ago.
Researchers at Georgia Institute of Technology reviewed ocean data going back to 1958 and “found that oxygen levels started dropping in the 1980s as ocean temperatures began to climb.”
Scientists have long predicted that as carbon pollution warms the globe, the amount of oxygen in our oceans would drop, since warmer water can’t hold as much dissolved gas as colder water. And, Georgia Tech researchers point out, falling oxygen levels have recently led to more frequent low-oxygen events that “killed or displaced populations of fish…

I do not see any empirical evidence in your article which supports your assertions.
I am interested in what you say and would like to look deeper.
Please refer me to the academic studies and observations that will help me undertand your article completely.
Cheers

Roger, it’s not my article. It’s a partial repost of an article that originally appeared in Climate Progress. You have to go back to the original article to see Joe Romm’s sources.

Well, Fukushima has already destroyed the Pacific Ocean and so add carbon and there you have it folks; disaster, disaster and disaster. And the ‘good’ news just keeps on coming.

Have you ever heard of The Saker, Shelby? I just listened to a really fascinating interview on Guns and Butter where he describes exactly how the US is going to collapse. He’s a former military analyst and describes how the US is quite weak right now – militarily, economically and politically. The US meets (exactly) 20 conditions the Soviet Union met before it disintegrated – which according to him happened because the Soviet leadership was incompetent (sound familiar?) to keep it from breaking into separate states. In my view the downfall of the US better come pretty quick now if there’s to be any chance of saving humanity.
