The "E" Word.

 

It was only a matter of time before the issue of mass extinction surfaced again.  Are we already in the throes of a sixth mass extinction event? If we are, what has caused it? What can we do about it? When?

A team of climate scientists from the University of Hawaii led by Robert Cowie has churned through the mountain of scientific literature and data and published a paper that has re-ignited the debate.  The good part is that it's a well-written report that non-science types can digest. The bad news is that no sane person will like the conclusions.

The authors conclude that we are indeed in an extinction event, the 6th in the 450 million year-history of life on this planet, and it's been underway for at least 30 years. 

If you're not up for reading the report and its mountain of footnotes, Vice.com has a pretty good summary.


“We consider that the Sixth Mass Extinction has probably started and present arguments to counter those who would deny this,” said the team, which also included biologists Philippe Bouchet and Benoît Fontaine of the Muséum National d’Histoire Naturelle in Paris, France, in the article.

“Denying it is simply flying in the face of the mountain of data that is rapidly accumulating, and there is no longer room for skepticism, wondering whether it really is happening,” added the authors.

...In addition to raising alarms about a possible mass extinction, Cowie and his colleagues address a range of counterarguments that they say downplay the severity of human pressures on world species, or even suggest that humans should harness these ecological changes for our own benefit.

The team argues that this kind of “laissez-faire attitude to the current extinction crisis is morally wrong,” according to the article, and advocates for more urgent measures to address the loss of species due to human activity.

“I feel obligated to express opinions about what we feel should be done given this crisis situation,” Cowie said. “I'm not just going to present the data and say be done with it. I'm going to say what we should do to resolve this issue, because it's an important issue.”

I won't dwell on this. The links are there if you want to read the paper itself or the Vice article.  Fill your boots.

    I suppose we would have a chance to reverse things if we could accept that we would have to stop never ending growth be it financial or, more importantly, population!

    I have read some interesting articles on population growth with the surprise of China losing population but as usual the fine print shows other sorrows with Africa exploding..

    It has long been known that much of the white fish we call Cod sold in our supermarkets could well be some subspecies caught off the African coast.
    When food becomes scarce world wide you know we are in trouble.

Up in Smoke. 300 Sq. Mi. of Amazon Rainforest Lost Every Day.

Image
  The Amazon rainforest is disappearing at what should be an alarming rate. 312 sq. mi. or 808 sq. kms. every day. Over the past 30 years humans have destroyed a patch of the Amazon equal in area to the states of Texas and New Mexico . The Amazon – historically a great carbon absorber, since trees take in carbon dioxide and release oxygen – now releases more carbon than it stores, which adds to, rather helps to reduce, our global climate crisis. Deforestation rates decreased slightly from 2004 to 2012. But since then, they’re back on the rise, especially in the past couple of years, since Jair Bolsonaro became president of Brazil. In 2018, as Bolsonaro campaigned as a patriotic man of the people, scientists predicted that once the Amazon lost more than 25% of its tree cover, it would become a drier ecosystem, all because deforestation changes weather patterns (due to how trees respire), which in turn reduces rainfall. Furthermore, as the forest becomes fragmented, areas surrounded by

The Cognoscenti Syndrome

  There is a group of people I think of as the Cognoscenti, people who are well educated, very informed and of rapidly diminishing relevance. Their ranks include writers such as Chris Hedges and Glen Greenwald. These are people who have honed an almost Puritanical value system, readily finding fault in any direction. They are scathing in their attacks on Republicans and Democrats alike to the point where they become nihilists. They don't endorse. They prescribe. This is where they fail. They're unable to advocate for anything that might resonate with the public whose interests they argue are being trammeled. Donald Trump was bad but Joe Biden is scarcely better. This is where their elitism comes in.  74 million may have voted for Trump but, hey, they didn't know any better. The mob that stormed the Capitol. They were just victims of the system venting their frustrations. All the racism, bigotry, xenophobia, misogyny, white nationalism - inevitable side effects of their oppr

"Creeping Normalcy" in the Plague Age

Image
  Britain is experiencing a new wave of Covid cases, 40,000 per day .  Yet it hasn't caused much reaction from the public. It sounds like the legendary stiff upper lip, the "Keep Calm and Carry On" resolve. Health officials think it's something much more troubling. “We’re in a phase where we still have large numbers of people dying from this disease,” said Linda Bauld, professor of public health at the University of Edinburgh. “But it has gone into the background. We’ve become used to something that has not gone away. I think there’s been a desensitisation to the mortality.” On Thursday, the UK reported more than 45,000 new coronavirus cases – the most since mid-July – and more than 800 deaths were reported in the past seven days. Hospitalisations are rising, with one-fifth of ICU beds occupied by Covid patients, and the latest figures showed an estimated 200,000 pupils absent from school. The UK is faring far worse than its European neighbours, with a rate of death
