Study of ancient rocks suggests oxygen depletion in oceans led to end-Triassic mass extinction

A team of researchers from the U.K., China, and Italy has found evidence that suggests oxygen depletion in the world’s oceans led to the end-Triassic mass extinction. In their paper published in the …

Extinction of cold-water corals on the Namibian shelf due to low oxygen contents

They were also able to link this event with a shift in the Benguela upwelling system, and an associated intensification of the oxygen minimum zone in this region. The team has now published their …

In ancient oceans that resembled our own, oxygen loss triggered mass extinction

Melting polar ice sheets meant sea levels were steadily rising, and ocean oxygen was falling fast around the world. At around the same time, a global die-off known among scientists as the Ireviken …

Volcanic activity, declining ocean oxygen triggered mass extinction of ancient organisms

Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today’s oceans at an alarming pace — so fast that scientists aren’t entirely sure how the planet will respond. Global climate change, fueled by …

Penguin Apocalypse: Adelie colony in Antarctica faces extinction as giant iceberg blocks sea (VIDEO)
RT
A massive nature drama involving some 10,000 Adélie penguins and an iceberg is playing out in an Antarctic bay opposite Australia. Scientists fear the colossal ice heap is blocking the birds from feeding in the sea, and they have already stopped hatching.

Going, going, gonzo: A famously twisted mind tackles the extinction crisis with a wicked pen

Ralph Steadman

Ralph Steadman is probably best known for illustrating the gonzo journalism of Hunter S. Thompson, famous for the book Fear and Loathing in Las Vegas. Thompson is dead and gone (per his final request, his ashes were loaded into a cannon and blasted into the air outside Aspen, Colo., in 2005), but Steadman, a Brit, is still very much alive and kicking at the age of 76.

Steadman’s latest work, a collaboration with filmmaker Ceri Levy, is a coffee table book called Extinct Boids. It’s bestiary of extinct birds, some of which are real (there’s the dodo, of course, and the great auk, and many lesser-known species) and others (the Rodrigues Blue-Back Throstle and the Mechanical Botanical Spunt, to mention a few) that hatched directly from Steadman’s and Levy’s imaginations.

Extinct Boids cover 2

It’s a strange and wonderful thing – Steadman’s ink-splattered illustrations narrated by Levy’s comic journalings and notes. Think John James Audubon on a lot of acid. But there’s a serious message here, too – about how little we know about the world around us, about the damage we’ve done, and the spirit and creativity we’ll need if we’re going to save a few scraps of it for the boids and other critters.

To learn a little more about the project, I caught up with Steadman and Levy last week for an hour-long video chat that ranged from trench humor to the time Steadman got vertigo while standing over a French toilet. I’ll spare you the latter tale and a few others. Hope you enjoy the rest. Read more

Has the extintion cascade already begun?

PARIS: Mankind may have unleashed the sixth known mass extinction in Earth’s history, given the known species losses over the past few centuries and millennia, palaeobiologists have reported.

Over the past 540 million years, five mega-wipeouts of species have occurred through naturally-induced events. But the new threat is man-made, inflicted by habitation loss, over-hunting, over-fishing, the spread of germs and viruses and introduced species and by climate change caused by fossil-fuel greenhouse gases, says the study.

“It looks like modern extinction rates resemble mass extinction rates, even after setting a high bar for defining ‘mass extinction’,” said researcher Anthony Barnosky from the University of California at Berkeley.
