The World Meteorological Organisation (WMO) is the UN’s authoritative voice on the behaviour of the Earth's atmosphere, its interaction with land and oceans, and the weather it produces. On 6 November WMO predicted 2017 to be among the hottest years recorded. A few days earlier NASA revealed maps of Greenland's coastal seafloor and bedrock beneath its ice sheet having up to four times as many coastal glaciers at risk of accelerated melting as previously thought. We are in a long-term warming trend with the highest ever recorded CO2 in the atmosphere and many unusual meteorological events this year, seemingly due to climate change. These issues were discussed at the COP 23 climate talks (6 to 17 November) in Bonn. Justin Welby wrote to the delegates to say that the Anglican community supports their work and recognises addressing climate change as an urgent priority requiring immediate attention. See
