To get climate change under control, experts say, we’re going to have to start sucking a whole lot more planet-heating carbon dioxide out of the air. And we need to start doing it fast.

It’s gotten to the point that not one but two major climate reports released over the past week say we’ll have to resort to a still-controversial new technology called Direct Air Capture (DAC) to keep our planet livable.
