Soil is the primary destination for the carbon captured from the air. It also benefits from the fertilizing effect that carbon delivers it, among others with compost or simply by the abundance of greens channeling some of the absorbed carbon down through their roots.
However, the temperature is already on the rise, and it will continue to rise in the future even after we stop emitting new CO2 because of all the carbon that is already in the air and which will stay there for some time. The weather and temperature make soil dry and reduces its carbon storage capacity. It is estimated, that the soil’s capacity to take in carbon will reach its peak (the tipping point) in the second half of this century, after which it will start to decline.
