Can the oceans solve our carbon removal problems?
There's been growing research and investment in projects that use the oceans to artificially remove carbon dioxide from the atmosphere. Such techniques involve both a biological and a chemical approach. To date, carbon removal technologies have been largely land-based, using giant air-purification machines, or planting trees to consume and store carbon. Those efforts have struggled to gain scale and acceptance. So, will a marine-based approach make any difference? It's a controversial idea and not without its difficulties.
