Carbon cycling in the world’s oceans. The flow of carbon dioxide across the air-sea interface is a function of CO2 solubility in sea water (Solubility Pump). The amount of CO2 dissolved in sea water is mainly influenced by physico-chemical conditions (sea water temperature, salinity, total alkalinity) and biological processes, e.g. primary production. The solubility pump and the biological pump enhance the uptake of CO2 by the surface ocean influ...

World carbon dioxide emissions by region, 1950-2006. Under the terms of the 1992 United Nations Framework Convention on Climate Change (UNFCCC), countries that have contributed the most greenhouse gas emissions have a responsibility to dramatically cut emissions and to assist the most vulnerable peoples and regions to adapt.
