Todays episode is embedded here:
Dr Andrew Glikson is an Earth and Paleo-Climate scientist and Visiting Fellow at the School of Archaeology and Anthropology at the Australian National University and author of the recent book entitled “The Plutocene: Blueprints for a Post-Anthropocene Greenhouse Earth”.
“Barring effective sequestration of carbon gases, and given amplifying feedback effects from the melting of ice sheets, warming of oceans, and drying out of land surfaces, Earth is bound to reach an average of 4℃ above pre-industrial levels within a time frame to which numerous species, including humans, may hardly be able to adapt.” We may survive the Anthropocene, but we need to avoid a radioactive ‘Plutocene’
Dr Glikson and myself discussed the consequences of a 4C + world and I mentioned the expose’ published by The Independent on 27th of October 2017, covered previously on this blog, where the Oil Giants Shell and B.P. admit that a 5C increase is ‘baked in’ before mid century: Oil Giants admit to a 5C Temperature Increase being baked in but no one else will.
Issues canvassed during the interview include possible nuclear war and the meltdown of the 450 nuclear power plants after the collapse of industrial civilisation, which will leave the planet bathed in ionising radiation of an order of magnitude greater than we have already spewed into the biosphere. There is a widely accepted theory that Industrial Civilisation will not survive a 4C global mean temperature increase. I personally will be surprised if it survives 3C.
Additionally we discussed the slowing down of the Atlantic Meridional Overturning Circulation and the effect this is having on the meandering jet streams, allowing warm ocean currents and air to enter the Arctic region and polar weather to escape further south than normal. There is no normal any more!
I became aware of Dr Glikson’s brilliant work after listening to him being interviewed on Radio Ecoshock in an episode titled “Can Humans Survive”
In a very generous and informative email exchange I had with Dr Glikson he sent me the following link documenting his and colleagues work: ANDREW GLIKSON 2.0 minutes to midnight in the clock of the atomic scientists This embedded link will take the reader to http://johnmenadue.com where more of Dr Glikson’s work is archived.
One point of difference between Dr Glikson and myself is whether or not humans will survive as a species. Dr Glikson believes there will be some survivors. I struggle with that possibility as I believe that habitat is collapsing now and we are terraforming this planet into something very different to the one we evolved on. I suppose it is the 7.6 billion people question that I will leave my readers to ponder. “Soon the living will envy the dead” author unknown.
In our email exchange Dr Glikson referenced the recent Washington Post article written by Michael E Mann et al titled: Doomsday scenarios are as harmful as climate change denial This from the same Michael Mann who along with colleagues came up with the “Hockey Stick Theory”. Now that all our graphs show that level of exponential ramping up of carbon and temperature Mann no longer sees the risk.
Speaking as I and Professor McPherson do about the imminent unraveling of the biosphere is sometimes deemed as ‘alarmist’ and we are often accussed of demotivating people. I reject that position entirely. Good people will continue to do the right thing irrespective and the military industrial complex within the corporate culture will continue to grind the living planet into dust. If you’re an environmentalist and not an anti-imperialist you’ve missed one of the primary drivers of the 6th great extinction.
