Earth’s surface was warmer last month than during any September on record, with temperatures since January tracking those of the hottest ever calendar year in 2016, the European Union’s Earth Observation Programme said Wednesday. The AFP reports that this year has now seen three months of record warmth – January, May, and September – with June and April virtually tied for first, the Copernicus Climate Change Service reported. While for the 12-month period through September, the planet was nearly 1.3 degrees Celsius above pre-industrial levels, which is alarmingly close to the 1.5C threshold for severe impacts detailed in a major 2018 report by the UN’s climate science advisory panel, the IPCC.
