The irony is that carbon now demonized IS THE BACKBONE OF LIFE ON EARTH. 2017 Worldwide CO2 Emissions - variwide chart (IEA ed. And it examined different scenarios for how much CO2 volcanoes were producing. They tell us that levels of carbon dioxide (CO 2 ) in the atmosphere are higher than they have been at any time in the past 400,000 years. 2019) This is a list of sovereign states and territories by carbon dioxide emissions due to certain forms of human activity, based on the EDGAR database created by European Commission and Netherlands Environmental Assessment Agency released in 2018.
