In other words, using the DAC approach to solve the climate problem would cost at least $5.1 trillion per year, every year, as long as we produce emissions. That’s around 6 percent of the world’s economy.
This is key. People often talk as if climate change is IMPOSSIBLY large, but 6% of the worlds economy means on the order of 5 years growth, so solving climate change might set us back by half a decade. (or more realistically, might mean that over the next 30 years, we have "only" the same progress we'd otherwise have in 25 years economically)
