Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

We find that without dramatic increases in the area of forests, without substantially positive changes in land - use practices, without large net positive effects of CO2 or climate change in the future, or without some other new significant carbon storage mechanism, the U.S. carbon sink itself will decrease substantially over the 21st century.

And in a world of accelerating sea level rise and climate change, in which farmland is being degraded and turned to desert, in which ever more land is set aside for carbon storage in the form of forest, and in which the strains of survival increase social divisions and social conflict, there is a new challenge: where will the 2bn climate refugees find new homes?

There are a wide range of hypotheses about the dominant controls and key parameter values governing land carbon storage, and a parallel range of ways in which these hypotheses are implemented in the codes of land models.

Some forms of carbon removal are also subject to significant debate, such as whether bioenergy with carbon capture and storage (BECCS)-- which involves burning biomass like crop wastes for energy and capturing and storing the carbon emissions underground in geological formations — can be truly sustainable at a large scale given competing needs for land, among other concerns.

A slight contemporaneous increase in 13C of atmospheric CO2 has led to the suggestion that this effect was caused by enhanced carbon storage on land (Francey et al., 1999b; Trudinger et al., 1999).
