Global warming mitigation strategies

According to a Perspective, human efforts toward carbon net neutrality and the reduction of non-CO2 pollutants by 2020 is estimated to result in a 50% probability of remaining below 1.5 °C  increase in global average temperature since preindustrial times; further, removal of 1 trillion tons of atmospheric CO2 before 2100 through carbon extraction and sequestration might be needed to increase the probability to 95%, thus limiting CO2 emissions during the span from preindustrial times to 2100 to 2.2 trillion tons and generating a cooling trend at 2100.
