This February was the warmest on record worldwide, according to new data from the EU's Copernicus Climate Change Service (C3S). This is the ninth month in a row that temperatures have broken records. This comes after last year was revealed to be the hottest the world has seen since records began. February was about 0.81 degrees Celsius above the 1991 to 2020 average for the month and one-tenth of a degree warmer than the previous record set in 2016. Just the ninth consecutive record-breaking month is surprising, but put into perspective he emphasizes the trend of continuous global warming.
In Europe, the last three months have been the continent's second warmest winter on record at 1.44C above average, only behind the 2019/2020 winter. Variation across Europe, however, means some countries saw their warmest winter so far this year. The National Observatory of Athens, for example, said this winter was the hottest Greece has seen since records began. It was 1.8 degrees Celsius warmer than the average winter from 1960 to 2024 and in some northern parts of the country, experts say temperatures rose much more. In this past decade, the country has experienced six of its warmest winters.
Poland saw temperatures between 3.5C and 7.5C warmer than average for February and Hungary recorded a national average of 7C above average. Globally, December, January and February all fell to 0.78C above average. But the last three months are part of a much bigger picture of climate change. There are several other factors that may have pushed the world to a peak, setting record after record over the past nine months.
El Nino, for example, has been in the headlines, driving high temperatures, extreme weather, drought and crop failures around the world. But if you compare this El Nino to previous ones, it hasn't been as extreme as those seen in the late 1990s. Overall, it's the fifth strongest since records began. Sea surface temperatures away from the equatorial Pacific, where El Nino has the greatest effect, have been "continuously and unusually high" for 10 months. In January, they were the highest on record, according to the World Meteorological Organization. This is worrying and cannot be explained by El Nino alone, it said.
As we move into La Nina – the opposite side of the climate pattern – temperatures may drop momentarily. Fluctuations like the current particularly active phase of the sun can add more energy to the system, making the world warmer and then cooler when their effect ends. Although there have been some surprises as the transitions are faster or stronger than experts predicted, "overall, what we're seeing now is pretty well aligned with what we expected to see maybe 20 years ago," according to Buontempo.
What do we know about the next six months, five or ten years? It's simple, he says, we know the average temperature will rise. While this continued warming scenario could be "disappointing or alarming" depending on how you look at it, Buontempo adds that it's at least one where we're lucky enough to know what's going to happen and therefore we are able to act on it.
