Note: carbon-cycle estimation: a plea for measurement of ocean carbon dioxide concentrations
Unless an effort is made to measure the carbon dioxide content of the oceans, the ability of researchers to distinguish between absorption by oceanic and by biotic sinks related to carbon emissions will remain imperfect. This uncertainty presently limits the ability of policy-makers to set a carbon emissions target fully consistent with that for carbon dioxide concentrations.Keywords: ...

Removal of carbon dioxide from the atmosphere to reduce global warming: a modelling study
We propose non–linear models to study the feasibility of removing CO2 from the atmosphere by introducing some external species such as liquid droplets and particulate matters in the atmosphere, which may react with this gas and get it removed by gravity. Further, this gas can also be removed by photosynthesis process upon using plantation of leafy trees around the sources of emission. The ...
