‘Holokauston’ of the Sea

The ocean is being burned alive. We might be next.

(I wish this were a joke. I just can’t find any humor in it.)

Ocean warming is killing the greatest places on Earth for life: the coral reefs. This slow warming during the past century has reached its tipping point, and we can now predict with clarity that an entire ecosystem is dying before our eyes.

As the scientist in this PBS report says, we could lose our reefs within 10 years. Predictions like this used to give us 100 years or so to save them, and that timeframe seems manageable, as if the next generation could solve this dilemma with ingenuity. But time is shrinking, and we might need to start thinking about living in a post-reef world—if we can live at all.

Humans have never existed without reefs, and we have no reference point for losing them. We have caused extinctions of singular species, but we’ve never come close to the extinction of an entire ecosystem. It is quite logical to assume that as the ocean and its shallow reefs go, so go we. An indirect, yet self-inflicted Holocaust.

The Greek word Holokauston refers to a burnt animal sacrifice. The slow burning of the reefs has the potential to sacrifice hundreds of coral species, thousands of fish species, and perhaps hundreds of thousands of associated species. We simply do not know the full scope of diversity on the world’s reefs, but they are estimated to contain a quarter of all species in the ocean.

How can such a rich system be dying? It’s inconceivalbe. Yet we know it is happening, we know why, and we know how to stop it.

It’s bloody murder.

Every thinking, breathing person needs to take a moment to decide: Do I care about people who will be alive within 10 years? If so, you must start caring, and caring deeply, about the ocean.

Any person with a heart and a brain will be outraged. You will go into the streets, get mad as hell, and get rid of any politician or business that is tone deaf on issues of climate change, global warming, and fossil fuel pollution. A climate denier, or a convenient “skeptic” who knows better, will be judged by history as complicit in murder.

I’m still not laughing.

With time running out, we probably have about 1 year left to turn this ship around. Even if you’re not convinced about the timing, is it worth the risk? Do you want to look back in a few years and judge yourself, and the human race, a complete failure?

You’ve got 2 marches on Saturdays to join this month.

Stand up for justice. The Holokauston of the Sea can, and must, be stopped.

 

 

 

 

 

Newest Climate Threat: The Ocean is Losing Oxygen

Shall we call this the “climate threat of the day?” With new evidence arriving daily of alarming trends and discoveries of previously unconfirmed effects from a changing climate, and a more broadly changing planet, it can be hard to keep up. Someone needs to publish a daily calendar with a fill-in-the-blank statement: “The thing that scares me the most today about planetary change is ____________________.”

For example:

The thing that scares me the most today about planetary change is ocean deoxygenation.

What is that? In essence, science has proven, just this week, that the global ocean has less oxygen today than in recent decades. The loss is greater than 2%, according to a new article in Nature by lead author Sunke Schmidtko. The trend has been predicted and demonstrated on local scales, but this composite study is the first to quantify it on a global scale.

The ocean is slowly suffocating, due to changes caused by us. If that much harm could happen within 50 years, I shudder to think what could happen within 500 years.

Wikipedia will need to update its definition of ocean deoxygenation, because it’s now an established observation, instead of a suggestion. [We also have a more immediate need of a sad Planet Ocean emoji. Here’s my sideways text-only version  (:<)  ]

Read more about this study in a Washington Post article by Chris Mooney that states: “The new study underscores once again that some of the most profound consequences of climate change are occurring in the oceans, rather than on land.”
