I noticed this too. In addition to planting forests that we then harvest and convert to biochar at peak rather than letting them decay and release carbon back to the cycle, we need to use energy intensive means to capture carbon. I have seen one proposal linked on HN that suggested direct use of a nuclear reactor's energy to do it... something like that would have the necessary power (pardon the expression) to make a dent in atmospheric CO2. Essentially, we need to build machines like the ones on LV427 in the movie "Aliens"...large structures that are essentially nuclear reactors with some extra equipment to use all their energy to terraform.... Terra.
