Phys.org  November 13, 2024 The scientifically recognized definition of Carbon Dioxide Removal requires removed atmospheric CO2 to be stored “durably”; however, it remains unclear what is meant by durably, and interpretations have varied from decades to millennia. An international team of researchers (Switzerland, USA – UC Berkeley) used a reduced-complexity climate model to examine the effect of Carbon Dioxide Removal with varying CO2 storage durations. They found that storage duration substantially affects whether net zero emissions achieve the desired temperature outcomes. With a typical 100-year storage duration, net zero CO2 emissions with 6 GtCO2 per year residual emissions would result […]
