Global temperatures were up by 1.3 degrees Celsius from pre-industrial levels in the 12 months leading up to this September. Meanwhile, Arctic sea ice saw its second-lowest average extent for decades, says a new report.
The Earth has experienced its warmest September since record-keeping began, according to a European Union agency's report published Wednesday.
The report showed that temperatures in Europe were particularly warm, with the cooling La Nina weather event in the eastern Pacific cooling parts of the southern hemisphere.
Arctic sea ice saw its second-lowest September average extent on record, more than 40% below the 1981-2020 average. Temperatures in Siberia were "especially high."

Paris Agreement temperature rise maximum is close
Monitors of the Paris Climate Agreement will view the figures with particular alarm: for the 12-month period through to September 2020, the planet was nearly 1.3 degrees Celsius (2.4 degrees Fahrenheit) warmer than pre-industrial levels.
This is close to the 1.5 degree Celsius threshold for severe impacts to the planet detailed in a 2018 UN climate report.
The Paris Agreement, of which many UN nations are signatories, has nations aim to cap global warming "well below" 2 degrees Celsius and at 1.5 degrees if possible.
Overall, September 2020 was 0.05 degrees Celsius warmer than September 2019.
