Increasingly Frequent Ocean Heat Waves Trigger Mass Die-Offs of Sealife, and Grief in Marine Scientists

Increasingly Frequent Ocean Heat Waves Trigger Mass Die-Offs of Sealife, and Grief in Marine Scientists

Heat waves recently extended across nearly 30 percent of the world’s oceans, an expanse equivalent to the surface area of North America, Asia, Europe and Africa.

Over the past several years, the temperature of the Earth’s oceans have been spiking high enough to trigger numerous die-offs of marine species, killing millions of corals, fish, mammals, birds and plants. Those mass die-offs also have sent a wave of emotional trauma washing over some researchers watching their life’s work vanish before their eyes.

“We talk a lot about eco grief, that sense of being overwhelmed and feeling loss,” said Jennifer Lavers, who has been tracking how thousands of seabirds have starved to death during recent ocean heat waves off the coast of western Australia as coordinator of the nonprofit marine research Adrift Lab.

Right now the extreme ocean heat in her region is waning, but globally, marine heat wave conditions extend across nearly 30 percent of the planet’s oceans, a surface area equivalent to all of North America, Europe, Asia and Africa. The harms of long-term gradual ocean warming are well documented, but Lavers said the most recent studies show that increasingly frequent pulses of extreme heat are doing the most damage to marine ecosystems.

With even more mass die-offs of ocean species projected, “scientists are leaving in droves from the field,” she said. “Incredibly skilled, talented, qualified, very passionate people are leaving because no matter what they say, what they do, how many papers they publish … It doesn’t matter.”

As Night Closes In

As Night Closes In

I was saddened to learn a few days ago, via a phone call from a fellow author, that William R. Catton Jr. died early last month, just short of his 89th birthday. Some of my readers will have no idea who he was; others may dimly recall that I’ve mentioned him and his most important book, Overshoot, repeatedly in these essays. Those who’ve taken the time to read the book just named may be wondering why none of the sites in the peak oil blogosphere has put up an obituary, or even noted the man’s passing. I don’t happen to know the answer to that last question, though I have my suspicions.

I encountered Overshoot for the first time in a college bookstore in Bellingham, Washington in 1983. Red letters on a stark yellow spine spelled out the title, a word I already knew from my classes in ecology and systems theory; I pulled it off the shelf, and found the future staring me in the face. This is what’s on the front cover below the title:

carrying capacity: maximum permanently supportable load.

cornucopian myth: euphoric belief in limitless resources.

drawdown: stealing resources from the future.

cargoism: delusion that technology will always save us from

overshoot: growth beyond an area’s carrying capacity, leading to

crash: die-off.

If you want to know where I got the core ideas I’ve been exploring in these essays for the last eight-going-on-nine years, in other words, now you know. I still have that copy of Overshoot; it’s sitting on the desk in front of me right now, reminding me yet again just how many chances we had to turn away from the bleak future that’s closing in around us now, like the night at the end of a long day.
