Andrew Glikson: 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.
Earth’s Climate Enters Uncharted Waters
The Shift in State of the Atmosphere
Andrew Glikson: The release to the atmosphere and oceans of hundreds of billions of tons of carbon from fossil biospheres, at the rate of >2 ppm CO2 per year, is
unprecedented in geological history of Earth, excepting events such as asteroid impacts which excavated and vaporized carbon-rich sediments, interfering with the carbon and oxygen cycles, which led to mass extinction of species.
CO2, Mass Extinction of Species, and Climate Change
Andrew Glikson: Lost all too often in the climate debate is an appreciation of the delicate balance between the physical and chemical state of the atmosphere-ocean-land system and the evolving biosphere, which controls the emergence, survival and demise of species, including humans.
