Agelbert NOTE: The Sixth Mass Extinction is here, no matter how much wishful thinkers deny it!


“As scientists we have a responsibility to be accurate about such comparisons.”

Like all extinction events, so far this one has been phased and complex, spanning tens of thousands of years and starting when our kind left Africa. Other mass extinctions buried deep in earth’s history have similarly played out over tens of thousands, even hundreds of thousands of years. To future geologists, then, the huge wave of extinctions a few thousand years ago as First Peoples spread out into new continents and remote archipelagoes will be all but indistinguishable from the current wave of destruction loosed by modernity and its growing appetites. Surely we’ve earned our place in the pantheon next to the greatest ecological catastrophes of all time: the so-called Big Five mass extinctions of earth history. Surely our Anthropocene extinction can confidently take its place next to the juggernauts of deep time—the Ordovician, Devonian, Permian, Triassic and Cretaceous extinctions.

Erwin says no. He thinks it’s junk science.

“Many of those making facile comparisons between the current situation and past mass extinctions don’t have a clue about the difference in the nature of the data, much less how truly awful the mass extinctions recorded in the marine fossil record actually were,” he wrote me in an email. “It is absolutely critical to recognize that I am NOT claiming that humans haven’t done great damage to marine and terrestrial [ecosystems], nor that many extinctions have not occurred and more will certainly occur in the near future. But I do think that as scientists we have a responsibility to be accurate about such comparisons.”

I had a chance to sit down with Erwin after his talk at the annual geology conference. My first question—about a rumor I had heard from one of his colleagues that Erwin had served as a sort of mass extinction consultant to Cormac McCarthy while the notoriously secretive author was constructing the post-apocalyptic world of The Road—Erwin coyly evaded. But on the speculative sixth mass extinction, he was more forthcoming.

“If we’re really in a mass extinction—if we’re in the [End- Permian mass extinction 252 million years ago]—go get a case of scotch,” he said.

If his power-grid analogy is correct, then trying to stop a mass extinction after it’s started would be a little like calling for a building’s preservation while it’s imploding.


“People who claim we’re in the sixth mass extinction don’t understand enough about mass extinctions to understand the logical flaw in their argument,” he said.  “To a certain extent they’re claiming it as a way of frightening people into action, when in fact, if it’s actually true we’re in a sixth mass extinction, then there’s no point in conservation biology.”   

“The only hope we have in the future,” Erwin said, “is if we’re not in a mass extinction event.”

Erwin is wrong. We ARE in the Sixth Mass Extinction. The evidence is overwhelming, and can't be ignored with pejorative descrptive adjectives like "facile" to describe the serious scientific research that proves we are in the Sixth Mass Extinction.


Wishful thinking
is the flaw in Erwin's argument (see Erwin having his morning coffee below:).


Erwin is CLEARLY ignorant (or in willful denial) of the following empirically obtained, irrefutable scientific evidence:

Industrial civilization has BOTH exceeded the maximum upper margin of the GHG (Greenhouse Gases) band by a huge margin AND has done it at a rate far above the ability of most complex non-microscopic organisms to adapt to these violent changes. Mammalian vertebrates, among the complex organisms on Earth, are the least able to adapt to rapid GHG concentration changes.

Earth's Sixth Mass Extinction Already Underway

Biodiversity hot spots of 80% of biosphere's species endangered by Global Warming Pollution 


Scientists warn in a new study that Earth is undergoing a sixth mass extinction that is "more severe than perceived."

Not only that, human activity—including pollution, deforestation, overpopulation, poaching, warming oceans and extreme weather events tied to climate change—is to blame for this massive loss in biodiversity, according to an analysis published Monday in the Proceedings of the National Academy of Sciences.

For the study, researchers from Stanford University and the National Autonomous University of Mexico analyzed data on 27,600 species of birds, amphibians, mammals and reptiles, comprising nearly half of known terrestrial vertebrates.

The results were shocking—about one-third of the species decreased in population size and range. Even common species are in decline.

"We find that the rate of population loss in terrestrial vertebrates is extremely high—even in 'species of low concern,'" the authors wrote.

Ecologist Gerardo Ceballos, an author in of the study, explained to the Atlantic how barn swallows, for instance, still number in the millions but are declining in many parts of their range.

"Even these common species are declining," Ceballos said. "Eventually, they'll become endangered, and eventually they'll be extinct."

Furthermore, in a detailed study of 177 mammals, the scientists found that all of the mammals have lost at least 30 percent of their geographic ranges between 1900 and 2015. More than 40 percent of those mammals—including rhinos, orangutans, gorillas and many big cats—have seen the land they once roamed shrink by more than 80 percent.

Without mincing words, the scientists described Earth's ongoing loss of wildlife as "biological annihilation" that will have "negative cascading consequences on ecosystem functioning and services vital to sustaining civilization."

Earth has witnessed five mass extinctions in its geological past during which the majority of living species were wiped from existence. The most well-known and recent extinction killed the dinosaurs. But instead of a massive asteroid, volcanic activity or other natural causes kicking off such an event, researchers in the new study argue that humans are to blame.

"In the last few decades, habitat loss, overexploitation, invasive organisms, pollution, toxification, and more recently climate disruption, as well as the interactions among these factors, have led to the catastrophic declines in both the numbers and sizes of populations of both common and rare vertebrate species," the study stated.

"Several species of mammals that were relatively safe one or two decades ago are now endangered," such as cheetahs, lions and giraffes, it said.

Biologist Paul Ehrlich, one of the scientists in the study, told the Guardian that their paper serves as a serious warning to humanity's own survival.

"The serious warning in our paper needs to be heeded because civilization depends utterly on the plants, animals and microorganisms of Earth that supply it with essential ecosystem services ranging from crop pollination and protection to supplying food from the sea and maintaining a livable climate," he said.

Quote
"The time to act is very short," Ehrlich added. "It will, sadly, take a long time to humanely begin the population shrinkage required if civilization is to long survive, but much could be done on the consumption front and with 'band aids'—wildlife reserves, diversity protection laws—in the meantime."

Mass Animal Die-Offs from Abrupt Climate Mayhem
Paul Beckwith

Published on Jul 14, 2017

Accelerating, abrupt climate change is an enormous threat to humanity, as outlined in the well written, long-overdue article "Uninhabited" published in New York Magazine. But it is even worse for non-human animals and plants. At least we regulate our body temperatures and some of us have access to air-conditioning.

What about animals that have body temperatures the same as their surroundings? Their metabolic rate doubles with a temperature rise of 18 F (10 C). Even a 2 C rise (Paris Agreement) increases metabolism 20%, decreasing lifetime 20%. Many species around our planet are today undergoing mass die-offs.

To me, it appears that Earth is losing its ability to sustain life, under the onslaught of human stupidity. Countries are dropping like dominos as infrastructure is decimated from abrupt climate change induced extreme weather.


Abrupt Climate Mayhem Now, in Spite of Main-Stream-Climatologist Posturing




Paul Beckwith

Published on Jul 13, 2017

Quite frankly, I am sick and tired of people, especially main-stream-talking-head-scientists, downplaying the huge unprecedented threats that are accumulating daily and will soon take down our civilizations. Our world is one that is full of specialists, with no ability to join-the-dots and recognize that humanities existence, and that of our entire ecosystems of plants and animals is degrading rapidly. Even exponentially. 
 

From my chair, I categorically state that anybody who downplays the significance and importance of our planets peril is part of the problem, and needs to get with the program or step aside so that the rest of us can do what is needed. The public needs the truth, no matter how bad it is to have any hope of changing course. And the truth is truly awful, at present

Jerry Brown: Climate Champion or Big Oil Ally?

California Gov. Jerry Brown poses as an anti-Trump climate-change savior, but his policies support Big Oil's agenda, says Adam Scow, California director at Food & Water Watch

Adam Scow is the California Director at Food & Water Watch. Adam oversees the California organizing program, which tackles some of California's greatest challenges to the long-term health of its water, energy and food.

SNIPPET from video interview:

DIMITRI LASCARIS:   Adam, I had the privilege of being in California earlier this year and I actually passed through some beautiful vineyards in the central valley area. To my astonishment, I saw oil pumps nestled among certain of the vineyards. These pumps were sucking oil out of the ground in the heart of one of the world's great wine producing regions. It struck me that such images simply don't fit with the mainstream media's narrative, where California is typically depicted as an environment leader. When it comes to support for the fossil fuels industry in particular, and fracking especially, how much do the policies of Jerry Brown's government actually differ from those of the Trump administration?

ADAM SCOW:   Well, it's a great question. The unfortunate fact is that they're not all that much better. California is a major oil-producing state. It's the third largest oil producing state in the country. In particular, Kern County is about 10% of the nation's crude. Indeed there are toxic oil operations, fracking, coexisting near agricultural fields, and creating a lot of pollution to our water and to our air. For the most part, the Brown administration here has supported big oil and their agenda. We've seen it in his refusal to ban fracking. In his current support of cap and trade, which allows big oil just to pay for its pollution, instead of making them reduce it, which is what we should be doing.
