“The Plutocene: Blueprints for a Post-Anthropocene Greenhouse Earth” – the latest from prominent Australian scientist Andrew Glikson. An hour of carefully documented doom and discussion, from nuclear folly to climate disaster. Nuclear weapons and climate change both threaten our existence, but with different time scales and probability. In his work on geology and paleoclimatology, with a specialty in the causes of past mass extinctions Dr. Glikson explains his bleak prognosis in this full program in-depth interview.

Credits: During the show, as part of our discussion, I play 3 short topical clips from 1959 movie “On the Beach” starring Ava Gardener and Gregory Peck.

Future Earth may be home to grass, bugs, and maybe, – maybe – a few humans. It’s a hot radioactive world, a time our next guest calls the Plutocene. This doesn’t come from a sci-fi writer or conspiracy blogger. We’ll be talking about the new book by a preeminent Australian scientist, Dr. Andrew Glikson.

Andrew is an Earth and paleoclimate scientist, currently a Visiting Fellow at Australian National University. He was educated in Australia, where he traveled extensively into the “outback” investigating the signs kept in some of Earth’s oldest rocks. He knows the science of climate, geology, asteroids, volcanoes, and nuclear radiation. All of that comes together in his new book “The Plutocene: Blueprints for a Post-Anthropocene Greenhouse Earth“. It is published by Springer, the serious textbook and science people.

Andrew and I have been in email contact at least since 2008, when I ran his speech at Australia National University – in the Radio Ecoshock show “A Warning from the Past” 080704. It’s great to talk in person, despite the bad news for living things on the planet. In addition to his dozens and dozens of peer-reviewed papers published in scientific journals, Andrew is a prolific author of articles.

You can listen to that 2008 speech by Glikson in my show right now, or download a Lo-Fi version of it here.

 

I offer this warning to delicate listeners: Dr. Glikson says the future may be, quote, “a post-Anthropocene republic of grasses and insects dominated by tropical climate and high radioactivity for at least 20,000 years.” In this interview we uncover how he arrives at the gloomy forecast.

Andrew is a paleoclimatologist, and Earth scientist. We discuss the existential threats of climate change in our second segment. But Glikson begins his new book with our outlook for nuclear catastrophe.

A WARNING LETTER FROM SCIENTISTS

But first we cover the letter Glikson organized with Australian scientists to warn their Prime Minister about the super risks posed by climate change. About 200 Australian scientists signed it, which Andrew says is about 10 % of them. There is still, as James Hansen says, too much “scientific reticence”. Maybe that’s not surprising considering Prime Minister Turnbull’s total turn-around from climate awareness to supporting giant new coal mines in his country.

There is also “media reticence” (or just plain climate denial) in Australia, where Rupert Murdoch owns most of the press, and the government funds the balance. Hardly anyone in Australia covered this unusual warning by scientists. You can read that letter from scientists here. As a tiny speck of Australian media with Radio Ecoshock on two small stations there, I read out the letter at the end of this show.

THE NUCLEAR WAR AGAINST NATURE AND OUR BODIES HAS ALREADY BEGUN

In Chapter One, Andrew writes that our addiction to war.

“It is becoming clear that, instead of channeling its remaining resources in an effort to protect its planetary biosphere, including its own civilization, under false flags H. sapiens continues to sink its efforts into murderous enterprises called war. This guarantees dissemination of radioactive nuclides on land, oceans and atmosphere, heralding the Plutocene, a geological era due to persist for tens of thousands of years, as recorded by the build-up of plutonium-rich clay layers in ocean sediments (Scott et al. 1983).”

I immediately began scribbling notes that nobody can “guarantee” the future. Maybe a large nuclear war will never happen. But then Glikson explains we have already lived through a kind of nuclear war with the Earth.

It’s painful to see the maps and descriptions of nuclear testing all over the world. It wasn’t enough to blow up parts of our own countries, in the United States, the Soviet Union, France and Britain – we had to irradiate other people’s lands. Glikson tells us about some of the places where testing took place, and who got the cancers.

Until I read this new book, I did not know much about China’s testing of nuclear bombs in the 1960’s. As Glikson explains, it wasn’t pretty, especially for ethnic populations on the Gobi desert fringe. Find out more in this article in Scientific American “Did China’s Nuclear Tests Kill Thousands and Doom Future Generations?”

In the new Plutocene book I found in Tables 2.2 and 2.4 this amazing fact: Americans on average get more radiation than most other humans. In fact, the average dose for an American is twice the world average.

By the way, if you think nuclear weapons madness has gone away somewhere, please read this Reuters article, published November 21st, 2017: “Special Report: In modernizing nuclear arsenal, U.S. stokes new arms race“. It’s horrifying.

CLIMATE DISASTER IN THE PLUTOCENE

Glikson studied the past great climate shifts and their causes. He sent me a time map showing those climate shifts, asteroid hits, and volcanic events – and that appears in his new book, courtesy of Keller, 2005. It shows the fundamental history of this planet – which you were never taught in school.

Keller G (2005) Impacts volcanism and mass extinction: random coincidence or cause and effect? Aust J Earth Sci 52:725–757

Glikson records the unstable climate during the last glacial interlude, but why? Why were humans formed during one of the most up and down periods of Earth’s history, rather than during the many million years of a hotter but more stable time? Are we biologically adapted to instability, depending on it, even though our civilization is not? Glikson says “yes”.

In the book, in Figure 1.8 and 1.9 we can see unequivocally where the big carbon emissions are coming from. A map from the Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, shows in 2010 the bright yellow and red high emissions from: the Eastern U.S. states, Europe, South Africa, India, China and Indonesia.

Figure 1.9, from NASA’s Orbiting Carbon Observatory, shows carbon concentrations in the atmosphere, again with the huge amounts over the same places. This is confirmed evidence.

The low producers are in the Canadian and American Rocky Mountains states, in the whole of South America, the rest of Africa, Russia and Australia. These are the less guilty parties, I suppose.

Glikson quotes the large recent paper from James Hansen et al, which says:

“These predictions, especially the cooling in the Southern Ocean and North Atlantic with markedly reduced warming or even cooling in Europe, differ fundamentally from existing climate change assessments.”

So I ask Andrew Glikson for his opinion on James Hansen, and the new theories he has presented lately. Glikson sees Hansen still the climate science leader.

DOOM: GLIKSON VERSUS MCPHERSON

It’s interesting to compare the dark vision from Australian scientist Andrew Glikson with the American scientist Guy McPherson. Both expect an over-hot radioactive world. The source of radioactivity is a little different: McPherson foresees a global meltdown of 400 nuclear power reactors, when the grid fails, for various reasons.

Glikson is more concerned with nuclear weapons, and military nuclear accidents. The world just experienced an accident related to plutonium in a weapons production facility in southern Russia. Along with Glikson’s theme that we may not know what happened, we only found out about this accident, weeks later, when a radioactive cloud drifted over Europe, where detection machines were set up after the Chernobyl nuclear power accident in 1986. Russia, as a closed society did not tell the world. China would not either. I’m not sure about America, whether the news would leak out along with the radioactivity.

There are two more major differences between Glikson’s future and that of Guy McPherson. Primarily, McPherson says we will go extinct, and has at times set a date for our extinction, whether it’s in 10 years or 35 years. Near-term extinction.

Glikson does not set any date for the demise of this civilization, but rather a threshold of 4 degrees C for climate, and a great question mark of when military nuclear madness may re-appear on planet Earth. Andrew does not say humans will go extinct. Some of us, perhaps only a few of us, may well survive, near the Arctic Sea, mountain valleys, or who knows where.

“In the wake of the Plutocene, following a period dominated by grasses and radiation-resistant organisms, mostly arthropods (insects, arachnids, myriapods), a resumption of a glacial period induced by the natural sequestration of CO2, orbital-driven cooling associated with the Milankovic cycle, and a gradual decline in radioactivity, habitat niches are occupied by survivors, including burrowing mammals. Depending on the intensity of radioactive contamination in different parts of Earth (Rubens et al. 1998), hunter-gatherer humans may survive in northern latitudes and cold high-altitude valleys (World Building 2016).”
– Glikson, “The Plutocene: Blueprints for a Post-Anthropocene Greenhouse Earth”

I do not feel qualified to judge, or predict the future in the developing chaos. I have some suggestions, but even those are not well enough formed to talk about yet.

I have been accused of going too far on nuclear fears. After my many programs on Fukushima, some listeners wrote to say they enjoyed the climate shows, but tend to excuse my over-the-top nuclear fears. After all, despite Fukushima, Japan is still there, and despite all nuclear testing and accidents, there are more humans on Earth than ever before. We are thriving…

But here, in this book from Andrew Glikson, we have the marriage of nuclear disaster and climate change, both going on together. That is the Plutocene. You can listen to Dr. Glikson’s speech at the book launch on Soundcloud here.
