Phys.org  April 15, 2024 An international team of researchers (Sweden, USA – University of New Hampshire, independent org., Northern Arizona University, University of Colorado, NASA, Germany, Finland, Australia, France, Denmark, Canada) has presented comprehensive budgets of CO2, CH4, and N2O by key permafrost land cover types over the period 2000–2020 across the northern permafrost region which was emitting green house gasses (GHGs) throughout the period. While the region was a source of methane and nitrous oxide, the carbon dioxide budget was near neutral with large uncertainties. Carbon dioxide emissions from wildfires and inland waters largely offset the sink in vegetated […]
