September 2019 was roughly 1.02 degrees F warmer than the average from 1981-2010.

Regions with the most markedly above average temperatures included the central and eastern USA.

"The recent ... record-breaking temperatures is an alarming reminder of the long-term warming trend."

The heat goes on.

The Earth just had its warmest September on record, tying a mark set in 2016, according to data released Friday by the Copernicus Climate Change Service, a European group that measures the planet's temperatures.

Globally, September 2019 was roughly 1.02 degrees Fahrenheit warmer than the average from 1981-2010, "making it the warmest September in our data record, although virtually on a par with 2016," the group said in a statement.

"Regions with the most markedly above average temperatures included the central and eastern USA, the Mongolian plateau and parts of the Arctic. Much below average temperatures were only recorded in a few regions, including southwestern Russia and parts of Antarctica," the group said.

The data continues Earth's hot streak, with June being the warmest June ever, and July the warmest month in recorded history, according to AFP. August was the second hottest August since records began. This all contributed to the warmest summer on record for the Northern Hemisphere, according to data from the National Oceanic and Atmospheric Administration.

"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 said to AFP.

"With continued greenhouse gas emissions and the resulting impact on global temperatures, records will continue to be broken in the future," Thepaut said.

This year's warmth is occurring without the heat from a strong El Niño event in the tropical Pacific Ocean, according to the Capital Weather Gang. El Niño is a natural climate pattern that often boosts global temperatures by bringing more ocean heat to the surface and adding it to the atmosphere.

A powerful El Niño occurred in 2015 and 2016, contributing to the record heat at that time, the Capital Weather Gang said.

September climate data from both NASA and NOAA, which also track global temperatures, will be released later this month.
