Beyond climate tipping points: Greenhouse gas levels exceed the stability threshold of the ice sheets

Abstract As the world keeps increasing its carbon emissions and exports,rising in 2018 to a record 33.1 billion ton per year, the atmospheric greenhouse gas level has now exceeded 560 ppm CO2–equivalent when methane and nitrous oxide are included, intersecting the stability threshold of the Greenland and Antarctic ice sheets.
