This is the title of a News & Views article of mine that just appeared in Nature. I had the opportunity to comment on a paper by colleagues from the noble gas and isotope community on the long-term fate of CO2 in natural gas fields. This is a hot topic because it relates to carbon capture and storage (CCS), a technology that may become important in fighting climate change.
Actually I don't think that the paper will or should have any great consequences with regard to CCS applications, but the media seem interested. I got several calls yesterday and for example the German magazine SPIEGEL has an article in its online issue today.
