The natural process by which green house gases are removed from the atmosphere is the photosynthesis. But due to rapid deforestation and increasing green house gases (CO2) there could be shortage of oxygen in future. Atmospheric percentage of oxygen is only 21%, still sufficient, due to oxygen cycle. The process of photosynthesis requires CO2, water and a tree. But while percentage of trees going down and down per density of population shortage of oxygen likely. Then how to carry out process of photosynthesis without trees. Is there any method or can it be developed in future?

How do we quantify the coupling of the carbon, water and energy cycles at the surface, in the boundary layer and in atmospheric vertical transports?

Photosynthesis is coupled to transpiration but not to surface evaporation off wet soils and wet canopies. The BL diurnal cycle and daily equilibrium involves all the surface fluxes and the radiation balance. The vertical transports are coupled especially through convective clouds, and cloud forcing feeds back on the SW and LW surface energy budget. We need to evaluate and quantify this coupled system in earth system models.
