March in Europe was 0.26 degrees Celsius above the previous hottest record for the month set in 2014, Copernicus said.
It was also “a month with contrasting rainfall extremes” across the continent, said Samantha Burgess of the European Centre for Medium-Range Weather Forecasts, which runs the Copernicus climate monitor.
Some parts of Europe experienced their “driest March on record and others their wettest” for about half a century, Burgess said.
Elsewhere in March, scientists said that climate change intensified an extreme heatwave across Central Asia and fuelled conditions for extreme rainfall which killed 16 people in Argentina.
PERSISTENT HEAT
The spectacular surge in global heat pushed 2023 and then 2024 to become the hottest years on record.
Last year was also the first full calendar year to exceed 1.5 degrees Celsius: the safer warming limit agreed by most nations under the Paris climate accord.
This represented a temporary, not permanent breach, of this longer-term target, but scientists have warned that the goal of keeping temperatures below that threshold is slipping further out of reach.
Scientists had expected that the extraordinary heat spell would subside after a warming El Nino event peaked in early 2024, and conditions gradually shifted to a cooling La Nina phase.
But global temperatures have remained stubbornly high, sparking debate among scientists about what other factors could be driving warming to the top end of expectations.
The European Union monitor uses billions of measurements from satellites, ships, aircraft and weather stations to aid its climate calculations.
Its records go back to 1940, but other sources of climate data – such as ice cores, tree rings and coral skeletons – allow scientists to expand their conclusions using evidence from much further in the past.
Scientists say the current period is likely the warmest the Earth has been for the last 125,000 years.
