Carbon Sinks

There are 5 carbon sinks that are actuatable on a short time scale:

  1. Atmosphere (smallest sink)
  2. Plants
  3. Topsoil
  4. Surface ocean layers
  5. Fossil Fuel Reserves (largest sink)

Carbonate rock and deep ocean are both long-term sinks that change on the order of 1000s of years.

However, recent advancements mean capturing CO2 in Carbonate rock has become a possibility. The CarbFix project capured and calcified 95% of the carbon emissions of a coal plant in Iceland. Of course, this process requires energy too, but it’s one more tool in the swiss-army knife.
