The European Union says it wants industrialised countries to put most of their efforts into practical measures to cut gaseous emissions by reforming energy and transport policies.
Just a fortnight ago, astronomers using the Hubble space telescope identified for the first time water vapour in the atmosphere of an exoplanet, albeit a gaseous one some 150 light years away.
That means a "gaseous mixture of populism and anti-imperialism", aimed at attracting middle-class support, says Alfredo Rangel, who was a security adviser to Mr Samper's government.
Natural gas is cooled to the point at which all other gases in the mixture have become liquid and only gaseous helium remains.Its attractions are many.
Gas is, by definition, gaseous at room temperature; oil is a liquid that can easily be transported.
These impoverished ecosystems, moreover, are dominated by Acidithiobacillus, one of the sorts of bug that turn hydrogen sulphide into sulphuric acid.Crucially from a practical point of view, Dr Hernandez found that the gaseous signal showing something amiss actually has two components.
It comes in a champagne bottle, and tastes very different from the gaseous mass-produced stuff that comes in screw-top bottles.
Since gaseous hydrogen is hard to store and handle, an alternative that some people have considered is to lock the hydrogen up in methanol, a liquid whose molecules are made of a carbon atom, an oxygen atom and four hydrogen atoms.
It could also help illuminate how giant, gaseous exoplanets often come to orbit their parent stars so closely.The dominant theory of planetary formation argues that each system started out as a cloud of debris orbiting a star.
In gaseous form the inert, lighter-than-air gas is used in a range of applications from welding and fibre-optic technology to deep-sea diving.
But on exposure to room temperature, it will instantly boil and revert back to its gaseous state.
