Dr Andrew Glikson is a paleo-climate and earth scientist at the Australian National University (ANU). The Western Australian Glikson Crater is named in his honor (see: http://www.abc.net.au/unleashed/stories/s2633053.htm ).
Dr Andrew Glikson on climate sceptics and the likely death of billions and end of civilization (April 2009): “As indicated by Clive Hamilton in New Matilda ( http://newmatilda.com/2008/05/19/death-rattles-climate-change-skeptics ) there is little evidence the “climate change skeptics” worry their misunderstanding of climate science may lead to the death of billions and the likely demise of civilization. The legal status of disinformation campaigns aimed at the promotion of substances of proven fatal consequences, such as ozone-destroying CFCs, or the release of CO2 to levels over 350 ppm ( http://www.columbia.edu/~jeh1/2008/TargetCO2_ 20080407.pdf ), may yet prove to be the Achilles heel of global civilization “ [1].
Andrew Glikson (Australian Earth and Paleoclimate scientist) on looming climate catastrophe, climate genocide and “existential calamity for civilization and nature”(2016): “Little mention is made of the existential threats posed by the climate and nuclear issues in the context of the current elections in the US and Australia. According to the world’s climate research institutions and the bulk of the peer reviewed scientific literature, the Earth has now entered a critical stage at which amplifying feedback effects to global warming transcend points of no return. Manifestations of a shift in state of the climate include; current rise in CO2 at 3.3 parts per million per year, the fastest recorded for the last 65 million years; extreme rises in Arctic temperatures; a plethora of extreme weather events such as cyclones, floods and fires; demise of habitats such as the Great Barrier Reef where corals die due to high water temperatures and coral bleaching; and other developments. The extreme rise of atmospheric carbon dioxide since the onset of the industrial age, and the corresponding rise in mean global temperatures as a direct result of the rise in carbon gases, pose an existential risk to the future of nature and civilization. The consequences of further burning of the vast carbon reserves buried in sediments and in permafrost and bogs can only result in a mass extinction of species which rivals that of the five great mass extinctions in Earth history… It follows that, where and when the majority of authoritative scientific institutions (NASA, NOAA, NSIDC, Hadley-Met, Tyndale, Potsdam, CSIRO, World Academy of Science, IPCC and so on), based on the bulk of the evidence, indicate beyond reasonable doubt that open-ended emissions of greenhouse gases inevitably lead to a major shift in the terrestrial climate, and thereby the demise of humans and of species, a toleration and/or condoning of continuing emissions by governments contravenes at the very least the spirit of international laws… 1. Since the mid-1980s an abrupt rise in the temperature levels of the atmosphere, driven by an increase in concentration of greenhouse gases arising from release of >600billion ton of carbon (GtC) to the atmosphere is leading to an extreme shift in state of the atmosphere-ocean system, such has no precedence in the recorded geological history, with the exception of events which resulted in the mass extinction of species, including massive volcanism, extra-terrestrial impacts and large-scale release of methane. 2. As a direct consequence of the above, as well as reduction of the transient protection by industrial sulphur dioxide since mid-1980s, mean global temperatures have risen since about 1970 by more than 0.6o Currently, had it not been for the aerosols, mean global temperature would have been higher by an additional near to 1oC. 3. Allowing for the masking effect of sulphur aerosols, the total rise in temperature since the onset of the industrial age ~1750 is reaching levels similar to those of the Pliocene period (~2.6 – 5.3 million years ago). The shift is occurring at the fastest rate recorded by paleoclimate studies. Whereas many species can adapt to gradual environmental changes, the current temperature rise rate resulting from ~2-3 parts per million (ppm) CO2/year may not be sustained. 4. The current change is manifested by an increase in the rate of melting of the major ice sheets, accelerating sea level rise and a rise in the frequency and intensity of extreme weather events, reflecting elevated energy level of the atmosphere-ocean system. 5.The consequences of continuing carbon emissions and consequent rise of mean global temperatures would render large parts of the Earth’s land surfaces uninhabitable due to temperature rise, droughts, storms and flooding of coastal, deltas and lower river regions by sea level rise – estimated as about 25+/-12 meters under Pliocene conditions, constituting an existential calamity for civilization and nature. 6. Excepting injection of transient short residence-time sulphur aerosols, the arrest of current climate trend would require (A) a meaningful reduction in current rate of carbon emission(~9 GtC/year) and (B) development of new methodologies for draw-down of atmospheric CO2, by at least 50 ppm, requiring research efforts on a global scale” [2].
Dr Andrew Glikson (2019): “According to Hans Joachim Schellnhuber, chief climate advisor to the European Union, “We’re simply talking about the very life support system of this planet”. As fascism and the horror of murderous hate crimes are on the rise, governments are presiding over runaway climate change leading toward mass extinctions of species, costing the lives of billions and the demise of much of nature, while children are protesting against the betrayal of their future… At +4 degrees Celsius above pre-industrial temperature, projected by the IPCC for the end of the 21st century, life on Earth could be depleted to levels such as existed in the wake of previous mass extinctions of species… Since many in authority do not accept, or only pay lip service to, climate science, it is a good question whether governments would be investing in adaptation measures in time. In particular no plans appear at hand for draw-down of CO2 – the one measure which could potentially arrest global warming. In this regard the reluctance to date to undertake meaningful mitigation measures does not bode well. The powers to be are now presiding over the greatest calamity that has ever befell on humanity and on much of nature” (Andrew Glikson, “The advent of extreme weather events and climate tipping points”, Countercurrents, 16 March 2019: https://countercurrents.org/2019/03/16/the-advent-of-extreme-weather-events-and-climate-tipping-points/ ).

Andrew Glikson on COVID-19 deaths versus climate deaths (2020): “Where the virus may potentially claim the lives of hundreds of thousands or even millions of people, global heating above 4oC is bound to claim the lives of billions, yet most governments hardly listen to the science. By the 25 March 2020 more than 4% of Covid-19 patients, nearly 19,000 people, tragically died worldwide, with more to come, and each death its own heartbreaking story. Many governments are listening to medical science, implementing essential measures to combat the plague, instigating social isolation and economic support systems in order to avoid a potential demise of hundreds of thousands or even millions of lives. Climate change is already causing deaths, according to a new report global warming would cause an additional 250,000 deaths per-year from heat and extreme weather events, yet most authorities continue to ignore the scientific evidence of climate disruption that threatens to exceed +2 degrees Celsius and toward 4 degrees Celsius. Potentially this is leading to a demise of billions of lives and many species through extreme weather events” (Andrew Glikson, “A viral climate of fear”, Countercurrents, 26 March 2020: https://countercurrents.org/2020/03/a-viral-climate-of-fear ).
