> Climeworks is planning to start operating a plant in Iceland later this year that will be capable of capturing 4,000 tons annually.

On average human activity puts about 40 billion tons of CO2 into the air each year.

How is this even remotely 'an option'? Stop fetishizing technosolutions.

Start planting trees today. We need a trillion of them.

"Lütke estimated the cost of sequestering carbon dioxide via DAC at the time was upward of $1,000 per metric ton."

That is vastly too high to be a feasible alternative for dealing with climate change.
