Alarming record breaking temperatures observed over four months globally

By Esther Nakkazi

The Global average temperatures for September 2019 was at par with September 2016, making it the fourth month in a row to be close to or breaking a temperature record according to the Copernicus Climate Change Service (C3S), a European Commission’s flagship Earth observation program.

At a global level, September 2019 also had high temperatures making it the fourth month in a row to be close to or breaking a temperature record at about 0.57°C degrees above average.

June 2019, was the warmest on record and July the warmest month ever recorded while August 2019 settling for the second warmest August. The data was compared against the latest standard thirty-year climatological reference period, 1981-2010,  and September 2019 was.

"September 2019 being on-par with record temperatures now acts as a reminder of the long-term warming trend," said the C3S which delivers freely accessible operational data and information services, which provide users with reliable and up-to-date information related to environmental issues.

“The series of record-breaking temperatures is an alarming reminder of the long-term warming trend that can be observed on a global level. With continued greenhouse gas emissions and the resulting impact on global temperatures, records will continue to be broken in the future,” said Jean-Noël Thépaut, Director of Copernicus ECMWF.

This is close to 1.2°C above the pre-industrial level as defined by the Intergovernmental Panel on Climate Change (IPCC) and about as warm as September 2016 (0.02°C warmer), the previous warmest September in this data record, he said.

The difference in the average temperatures for September 2019 and September 2016 is very small, according to the C3S data, only 0.02°C. It is smaller than the typical difference between the values provided by the global temperature datasets of various institutions, both months will share the top spot together.

Regions with most markedly above-average temperatures include central and eastern USA, the Mongolian plateau and parts of the Arctic. In Europe, temperatures were above average over most of the continent, especially in the south and south-east.

The Copernicus Climate Change Service (C3S) is implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the European Union. ECMWF also implements the Copernicus Atmosphere Monitoring Service (CAMS). ECMWF is an independent intergovernmental organization, producing and disseminating numerical weather predictions to its 34 Member and the Co-operating States.

The Copernicus Climate Change Service (C3S), Monthly Climate Summaries from the Copernicus Climate Change Service (C3S) routinely publishes monthly climate bulletins reporting on the changes observed on the global surface air temperature, sea ice, and hydrological variables. All the reported findings are based on computer-generated analyses using billions of measurements from satellites, ships, aircraft and weather stations around the world.
