This is according to a new report from Europe's Copernicus Climate Change Service. Compared to averages from 1981 through 2010, Copernicus adds this one was higher by 1.02 degrees Fahrenheit. 2019 barely tops September 2016, the former title-holder. But the difference is so small, AFP reports Copernicus is giving them a joint title. Regions with the most markedly above average temperatures included the central and eastern USA, the Mongolian plateau and parts of the Arctic, Copernicus Climate Change Service, via statement. Much below average temperatures were only recorded in a few regions, including southwestern Russia and parts of Antarctica, Copernicus Climate Change Service, via statement. September joins a few other months this year that broke or nearly topped worldwide heat records. June 2019 was the hottest for its month, while August 2019 ranked second. Sandwiched in between them, this past July was the warmest month ever recorded. The recent series of record-breaking temperatures is an alarming reminder of the long-term warming trend that can be observed on a global level, Copernicus Director Jean-Noel Thepaut, via AFP.
