January 2025: Record-Breaking Warmth Amid La Nina’s Cooling Influence

January 2025 marked the warmest January on record, with average temperatures 0.09 degrees Celsius higher than January 2024, and 1.75 degrees above pre-industrial levels. La Nina’s typically cooling effect did not temper these record temperatures, as the planet also saw the hottest year in 2024. The World Meteorological Organization emphasized the importance of tracking these trends to address climate change effectively.

In January 2025, the planet recorded its hottest January ever, despite the cooling influence of La Nina, as reported by the European climate agency. This follows 2024, which was marked as the warmest year on record, registering a notable increase of 1.5 degrees Celsius above pre-industrial averages. The Copernicus Climate Change Service highlighted that January’s average temperature reached 13.23 degrees Celsius, surpassing the previous record set in 2024 by 0.09 degrees and exceeding the 1991-2020 average by 0.79 degrees.

Scientists indicated that January’s temperatures were 1.75 degrees Celsius higher than pre-industrial levels, with global temperatures remaining above the crucial 1.5 degrees Celsius mark for 18 out of the preceding 19 months. Samantha Burgess, the Deputy Director of C3S, commented on the unprecedented temperatures observed despite La Nina conditions, which typically provide a slight cooling effect. La Nina, characterized by cooler surface waters in the central Pacific, often influences global weather patterns significantly.

La Nina usually results in intense monsoons and increased rainfall in regions such as India, while contributing to drought conditions in parts of Africa and South America. Nevertheless, recent reports indicate that sea surface temperatures have remained at exceptionally high levels worldwide, with January’s average sea surface temperature recorded at 20.78 degrees Celsius, making it the second warmest January historically.

The Copernicus data further revealed that the preceding 12-month period, from February 2024 to January 2025, was 1.61 degrees Celsius warmer than pre-industrial levels. In addition, evidence presented shows that even during visible La Nina conditions, ocean temperatures in the eastern Pacific were found exceeding normal ranges. Furthermore, the Arctic region recorded its lowest sea ice extent for January, declining 6 percent below the average, nearing the record low of January 2018.

The World Meteorological Organization previously announced that 2024 was the warmest year on record, indicating a global mean temperature 1.55 degrees Celsius higher than the baseline period of 1850-1900, which preceded the significant climate impact of human activities like fossil fuel combustion. It is essential to note that a permanent breach of the 1.5-degree Celsius threshold from the Paris Agreement pertains to long-term temperature increases observed over a span of 20 or 30 years.

The article discusses the unprecedented temperature records experienced globally, particularly focusing on January 2025, which set a new high despite the presence of La Nina—typically known for inducing cooler weather patterns. This situation raises concerns about climate change effects, as the warmest years continually surpass earlier records, particularly in light of human-induced activities. La Nina’s interaction with global temperatures is critical for understanding climate variability, as it contrasts with El Nino, which tends to elevate global temperatures. The implications of these rising temperatures resonate with broader discussions on climate change and the urgency to meet international agreements such as the Paris Agreement, aimed at limiting temperature increases. Consequently, ongoing monitoring of sea surface temperatures and Arctic ice extent provides vital insight into the state of the planet’s climate system and helps forecast future conditions.

In summary, January 2025 experienced record-breaking temperatures, exceeding previous highs despite the cooling impacts generally associated with La Nina. This trend surfaces significant concerns pertaining to ongoing climate warming, particularly considering the operational definitions and implications of international climate agreements. Continuous observation and analysis of global temperatures and the interrelation with climate patterns are crucial in the effort to mitigate future climate change impacts.
