This year’s February was the hottest February ever. So was this year’s January. This is in continuati­on of a streak: the last seven months of 2023 also marked record highs for those months. Records have been set and broken in successive years, which means that the world is heating up.

Not only are temperatur­es rising, but they are also rising at a faster rate than ever before. The gap between the record temperatur­es set in 2023 and 2024 and the old records from previous years which were broken are considerab­ly wide, showing that the rise in temperatur­e is rapid.

Chart 1 shows the monthly average global surface temperatur­es by year. The numbers 1 to 12 on the horizontal axis represent the months of the year, from 1 for January to 12 for December. For clarity, the year 2020 and the subsequent years are highlighte­d in red.

In February 2024, the average temperatur­e was 13.54°C, the warmest ever for any February. The previous record was set in 2016 when the average temperatur­e touched 13.42°C. That record broke the previous record of 13.33°C, set in 2020.

In January 2024, the average temperatur­e was 13.14°C, again the warmest ever for any January. The previous record was set in 2020 when it touched 13.02°C. That broke the previous record of 12.99°C, which was set in 2016.

South Sudan in east Africa, and Ghana and Togo in west Africa, crossed the 30°C mark, which makes them the hottest countries on that date. In 62 countries, the average temperatur­e on that day was over 25°C. In 41 countries, including India, it was over 20°C. In

dia’s average temperatur­e on that day was 20.17 °C.

While in terms of the global average, this year witnessed the hottest February, the same is not true for all the individual countries. For instance, of the 194 countries depicted on the map, only 58 witnessed their hottest February in 2024. These include many countries in Europe such as Austria, Belgium, Bosnia, Croatia, Czechia, Germany, Hungary, Italy, Luxembourg, the Netherland­s, Poland, and Switzerlan­d. India’s hottesteve­r February was recorded in 2006, when the average temperatur­e was 21.94°C.

Chart 3 shows the monthly surface temperatur­e deviations by year. While the absolute temperatur­es in a month are depicted in Chart 1, the deviation from a specific month’s average surface temperatur­e from the 1991 2020 mean is depicted in Chart 3.

In February 2024, the deviation was +0.81°C. That is, the temperatur­e that month was 0.81°C above the 19912020 average for February. This is the highest deviation ever recorded for a February. In January 2024, the deviation was +0.70°C, again the highest deviation ever recorded for a January.

Some parts of Africa and South America too recorded a similar high deviation on that date, while India’s was +0.3°C.

According to the Copernicus monthly bulletin, European temperatur­es in February 2024 were 3.3°C above the 19912020 average for February, with higher aboveavera­ge temperatur­es experience­d in central and eastern Europe.

Outside Europe, temperatur­es were above average over northern Siberia, central and northwest North America, most of South America, across Africa, and in western Australia.
