Abstract
Many modeling studies depend on direct air capture (DAC) in their 1.5°C stabilization scenarios. These studies rely on assumptions that are overly optimistic regarding the cost and scaling-up of DAC systems. This can lead to highly misleading results that can ultimately impact the ability to reach climate stabilization goals.
Remember kids, it takes as least as much energy to put the carbon back as we got out of it when we released it. And because this is the real world and not some math on paper it takes somewhere between 8 and 12 times as much energy to put it back as we got out of it.
People think gas is expensive now, it should have been at least 10 times more expensive if we wanted it to be carbon neutral. Think about all the power we used by releasing carbon in just one year, we would need 10 years just to put it all back. Gasoline has powered the modern world, but it turned out to be a curse instead.
