Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.
Current global observational and modelling capabilities allow scientists to produce estimates of the carbon budget, but many uncertainties remain. An EU-funded initiative was therefore established to provide more and better data on carbon dioxide (CO2) and methane (CH4) through a global carbon observation and analysis system.
