Tim Flannery goes into as much detail as he can about carbon sequestration opportunities in the time allotted for his lecture below.
The goal of keeping global average temperatures below 1.5°C above pre-industrial levels is a noble one, but it instantly points to the inadequacy of our current approaches to reaching such a goal. At this late stage in the game, even instantaneous full decarbonization of the global economy (i.e. instantly removing all dependence on gasoline, natural gas, diesel fuel, and all other carbon emitting power sources) does not give us time to achieve 1.5°C or better. This means that we need to actively remove CO2 from the atmosphere on an industrial scale using technologies that are both un-proven and un-discovered. Flannery’s talk dives directly into this important frontier with important implications for government and business research and development opportunities. One of my favorite videos of the year! Thanks to Pirate Television for recording it.
