Professor Corey Bradshaw explains the unfolding “Extinction Cascades” on Nature Bats Last.

Professor Corey Bradshaw from Flinders University was this months guest on Nature Bats Last.

The audio of the episode is embedded here:

“Dr. Bradshaw is the Matthew Flinders Fellow in Global Ecology at Flinders University, where he directs the Global Ecology Laboratory and is also Chief Investigator of the ARC Centre of Excellence for Australian Biodiversity and Heritage. He heads the Flinders Modelling Node of the latter organization. Professor Bradshaw has published some 300 peer-reviewed scientific articles, 11 book chapters and 3 books. His book titles include The Effective Scientist, published by Cambridge University Press and, from Chicago University Press and co-authored by occasional guest on this show Professor Paul Ehrlich, Killing the Koala and Poisoning the Prairie. In total, his work has been cited more than 20,000 times. Bradshaw is co-Head of the Ecology Section of the Faculty of 1000 and a Fellow of the Royal Society of South Australia. He was awarded the 2017 Verco Medal from the Royal Society of South Australia, a 2017 Rockefeller Foundation ‘Bellagio’ Writer’s Fellowship, the 2010 Australian Ecology Research Award from the Ecological Society of Australia, the 2010 Scopus Young Researcher of the Year, the 2009 HG Andrewartha Medal, and a 2008 Young Tall Poppy Science Award. He is regularly featured in Australian and international media for his research. The Professor’s blog has been visited more than 2.3 million times.” Quoting  Professor Guy McPherson

Links to Professor Bradshaw’s published works are embedded here, his personal blog with a subscription option is Conservation Bytes 

“More than 99% of all species that have ever existed have gone extinct”. See the short presentation at the top of the Professor Bradshaw’s blog for more on that diamond of information and lets get over our human hubris and invincibility.
We have previously discussed on the show Professor Bradshaw’s work with Professor Paul Ehlich. That episode is embedded in the following link: Professor Paul Ehrlich returns to Nature Bats Last
Until recently I assumed that at least Tardigrades would get through the extinction bottleneck. That has recently be called into question as we discussed on the show and  below;
“Tardigrades are tough little critters. When conditions get nasty, they can dry out, reconfigure their bodies and enter suspended animation – called dessication – for years. You can throw virtually anything at them: frozen temperatures, zero oxygen, high pressures, the vacuum of space, cosmic radiation, and even being boiled.”

“But new research has shown these tiny organisms may have a weakness – long-term exposure to high temperatures, even in their dessicated state. The longer the temperatures are maintained, the lower the tardigrades’ chances of survival.”
Tardigrades Are Basically Indestructible, But Scientists Just Found Their Weak Point

In the following embedded Flinders University presentation Professor Bradshaw jokes that his colleagues describe him as Dr or Professor Doom. This subtle form of gas lighting has stoked scientific reticence as the extinction event accelerates, discouraging the less courageous scientists from telling you what they really think is unfolding. Professor Guy McPherson and I admire Professor Bradshaw’s courage, professionalism and scientific integrity. BRAVE | There’s No Plan(et) B – What you can do about Earth’s extinction emergency.

Carl Sagan Extinction is the rule.

Professor Bradshaw and I discussed the Great Barrier Reef in Australia. Embedded below is the trailer to a new documentary titled “Murder On The Reef”

All my time at sea over 16 ‘blue water’ passages and hundreds of races taught me the importance of the “Precautionary Principal”. The prudent skipper needs a wide margin of error. Caution and prudence seems to have been cast to the wind as the dominant culture grinds the living planet into dust.
Next months guest will be Jeff Gibbs, director of “Planet of the Humans” recently censored off You Tube for daring to question the renewables sector.

I'm an anti-imperialist, environmental activist and blue ocean sailor, who is passionate about the earth and all it's inhabitants without favour. Brace for imminent impact as we bare witness to the non-linear unraveling of the biosphere and habitability disappearing for most if not all complex life on the only habitable planet we know of. To quote President Niinistö in North Russia: ‘If We Lose the Arctic, We Lose the World’. Folks we have lost the Arctic.

  1. I’ve got the answer! We just need to find some Unobtainium and all our worries will be taken care of by the new corporation that will take complete control and save us all. And don’t worry, these will be NICE corporate rulers who will give all those miner kids unlike the current corporate heads that won’t. Those clips included made this all so clear!

    Or maybe it was the fungi chocolates talking about magical non-thinking…

    And Hansen didn’t relate what he told Congress to any of the papers that had already come out on Global Warming/Greenhouse Effect. I never thought about that before. Hmmmm.

    Well of course it’s about maintaining the status quo for these powerpoint people. Who wants to be broke and poor and going to the food bank every week? Who wants to never afford another vacation, ever? Mann has a good gig and knows it and he did give the world the Hockey Stick graph after all! He just needs to keep the game going until, of course, it all goes tits up but not until after he dies of old age which is probably his magical hope.

    And if we can’t discover Unobtainium, we have this to fall back on!

    Nuclear Fusion: Why the Race to Harness the Power of the Sun Just Sped Up

    Fusion companies have now raised $2.3 billion in investment, believing they can begin producing unlimited amounts of zero emissions energy by the 2030s.

    And no, I don’t hear a single word about the lag time between emission of GHGs and when the effects hit. Not a peep just about everywhere I read.

    I hope Guy appreciates my not sending him any questions whatsoever.

  2. […] “Climate change is one of a host of environmental ills for which technological solutions are being proposed. In fact, most of the proposed solutions exacerbate environmental ills in other dimensions such as species loss and mass extinction. This tendency of technological reasoning to ‘bleed’ from one dimension or axis to another— to cause unintended consequences, is a function of the structure of this type of reasoning.”“Paradoxically, calls for analytical rigor tend to narrow the realm of scientific concern, thereby raising the range of unintended consequences. This paradox is internal to the structure of technological reasoning. In practical terms, the 2018 IPCC Report on climate change relies on dubious technology to produce ‘negative carbon emissions.’ This both distracts attention away from more plausible methods and it could wildly exacerbate mass extinction.” Climate Change and Technology Mark Brimblecombe’s piece de resistance on the mitigation myth is a must read; “It is not nice to be told that you have been diagnosed with a terminal condition. It is even worse to be given false hope that if you did this or that you could mitigate the problem or turn it around when it cannot. If a medical practitioner does this, they lose their job. But climate scientists do this frequently, and probably to keep their job. It is virtue-signalling to agree with national and international climate agreements which propose that we can fix this by reducing (mitigating) our carbon footprint and carbon emissions… and so continue ‘business as usual’ and live happily ever after.” Climate Change and the Mitigation Myth In the above video I mentioned the paper by Professor Corey Bradshaw suggesting that even Tardigrades are in danger. Our interview with Professor Bradshaw and links to the paper we discussed are embedded following; Professor Corey Bradshaw explains the unfolding “Extinction Cascades” on Nature Bats Last. […]

    “Curtin-led research has revealed an increase in levels of both acid and hydrogen sulfide in the ocean was the double whammy that wiped out marine life during a mass extinction event 201 million years ago.”

Kevin Hester is currently living on Rakino Island, a small island in the Hauraki Gulf near Auckland, New Zealand, monitoring the unravelling of the biosphere and volunteering at the Rakino Island Nursery is currently developing a proposal to create a marine reserve near by. The Island has no grid tied electricity or reticulated water.  I catch my own water from the roof and generate my electricity from the ample solar radiation on the island.
