We really have no idea how the carbon cycle(s?) function, now do we.


In the Swedish article in DI it is mentioned that 1/4 to 1/3 of carbon dioxide "disappears" inexplicably over land in the northern hemisphere, no-one knows how or where.

New discoveries show biological formation of oxygen in soils

Summary:

In the 1930s, the ability of green plants to form oxygen through oxidation of water -- photosynthesis -- was discovered. Since then, no other large-scale biological formation of oxygen has been found, until now. New research results show that down in the dark depths of the soil, a previously unknown biochemical process is under way, in which oxygen is formed and carbon dioxide is reduced to organic material.

"Global microbial biomass at a glance

The number of intra-terrestrial microbes varies notably depending on the underground site studied. Values in the range of one thousand up to one hundred million microbes per ml groundwater or gram sediment are commonly reported. Although the dry weight of hundred million microbes in one gram of sediment is very small, in the range of 1 - 10 micro-gram, the total weight of microorganisms in many square kilometres of seafloor and continental shelve sediments, rock aquifers etc. may reach an impressive number. An attempt to estimate the total carbon in terrestrial and intra-terrestrial environments was made recently. These calculations indicate that the total amount of carbon in the intra-terrestrial organisms may equal that of all terrestrial and marine plants. Although subject to a great deal of uncertainty, the estimates suggest that the biomass of intra-terrestrial life is very large. A wealth of microbial life may exist deep inside Earth with many new species, representing novel microorganisms with unique physiological and biochemical features that await exploration."
