Late Thursday morning, November 16, 2017, at a packed announcement in the European Union meeting room at COP23, environmental ministers from Canada and the UK offered perhaps the most promising news to come out of the 23rd UN climate summit. They announced a coalition of 19 countries and two US states pledging to phase out all coal burning by 2030. My editor Glenn Scherer agreed that it was a good idea to close out my coverage from COP23 with a more upbeat story. That’s what this is (link here). The story closes with a wrap-up of the work left undone.
