Footage of Carl Sagan addressing Congress on the threat of climate change has been making the rounds on social media after September smashed the monthly temperature record by “an extraordinary amount”.
Land and sea temperatures have shocked scientists with 2023 set to be the hottest year on record.
The EU’s Copernicus Climate Change Service (C3S) said last month was the most anomalous month they have seen since they began recording in 1940, measuring an average surface air temperature of 16.83C (62.29F).
This is 0.5C warmer than the previous September record set in 2020 and 1.75C warmer than then pre-industrial average – between 1850-1900.
Europe was 2.51C higher than the 1991-2020 average and 1.1C warmer than September 2020, the previous record.
Here’s Sagan warning what would happen to the Earth back in 1985:
