Alarm also for Arctic sea ice: in September the extension was the second lowest ever recorded, both for the daily one and for the average monthly extension.
These are the latest data from the Copernicus Climate Change Service for observing climate change from the European Union's Copernicus program.

Much of the continent, particularly the southeastern areas, experienced above-average temperatures during the month.
However, underlines Copernicus "from the time series, similar levels have been recorded several times in the last two decades and are no longer considered unusual".
In particular, the Copernicus Climate Change Service still notes, the global temperature anomaly from the beginning of the year shows that 2020 is on par with 2016, the hottest year on record.
Also, for the same period, 2020 is warmer than 2019, the second warmest year currently on record.
In the last three months of 2020, climatic events such as La Niña and likely low levels of autumn arctic ice cover will affect the year as a whole, set to become the hottest on record.
