Microsoft’s million-tonne CO2-removal purchase – lessons for net zero
- lkbm 5y agoInteresting bit about geosphere vs biosphere. Every time someone mentions for carbon sequestration tech, people snarkily claim we're just reinventing trees. That said, I don't think that a benchmark of "keep it sequestered for 1,000 years" is at all sensible. Unless society completely collapses, it's clearly more viable to sequester for 100 years using today's technology and then sequester 900 more years using 2120 technology than it is to just sequester for 1,000 years using today's technology.
