Atmospheric methane removal seems doable, maybe a prototype for CO2 removal. It's easier because it doesn't have to be buried: it could just be burned to convert to CO2 with a much smaller warming impact.
- ArkVark 6y agoExcess atmospheric CO2 still causes major problems with human cognition and building ventilation. At about 800ppm there are measurable falls in human cognitive performance. Might not happen outside for a while, but the increase to the outdoor level makes ventilation much more difficult.
