Two-thirds of the world’s surface was scorched by a month or more of record-breaking heat, Guardian analysis of satellite data can reveal.
In oceans and on land, from Colombia to China, and from the north to south pole, records for the monthly average temperature were smashed time and time again last year – in some cases, by as much as 5C (9F) hotter than the previous record.
The Guardian took the average temperatures for each month in 2024, as recorded by the EU’s Copernicus Climate Change Service (C3S), and compared them with the hottest month since 1979.
