Agreed on the need to invest in carbon capture now. My main argument was that a) reducing emissions to ~0 is going to be necessary even if we invent some insanely efficient carbon sequestration tech; b) the longer we wait, the worse the problem gets, in an exponential way. Emissions reproduce; c) Therefore the bulk of our effort should be spent trying to get emissions down to 0. Because if we fail at that (a task that we know how to accomplish), then no amount of sequestration tech will save us.
