Category talk:Keeling Curves

Proposed Category Greenhouse gas concentrations

This cat. contains multiple images that span a time period far beyond the 1950s (see en:Keeling curve), more files depicting ghg-concentrations, which don't really fit in here, are contained in Category:Global warming graphs and other places. In parallel to Category:Greenhouse gas emissions I would like to create a new cat. "Greenhouse gas concentrations" or, perhaps, "CO2 concentrations". This Category:Keeling Curves here would become a subcat. Opinions, objections? --DeWikiMan (talk) 08:20, 20 March 2017 (UTC)
