Just adding on to this, some math: The US emits about 11 gigatonnes of CO2 per year. At $150/ton, sequestering it all would cost 1.65 trillion dollars or about 8.25% of GDP. That's about what we spend on social security and the military combined. So, it's a lot. But it's possible to imagine doing it. I kinda wish there was a company with a bunch of sequestration equipment out somewhere that people could just give money to in order to suck out more CO2 from the air. Why doesn't this exist yet?
