Language is a system that consists of the development, acquisition, maintenance and use of complex systems of communication, particularly the human ability to do so; and a language is any specific example of such a system.
Henry Drummond: Language is a poor enough means of communication. I think we should use all the words we've got. Besides, there are damned few words that anybody understands!

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.
