  • ENSO Impact on the Declining CO2 Sink Rate
    SUMMARY: A simple time-dependent CO2 budget model shows that yearly anthropogenic emissions compared to Mauna Loa CO2 measurements gives a declining CO2 sink rate, which if continued would increase atmospheric CO2 concentrations and presumably anthro…
