According to Carlo Buontempo, Director of the Copernicus Climate Change Service, April 2024 marked another milestone in global warming trends. Buontempo noted, "If you look at the temperature it's yet again another record-breaking month, and this means that the sequence, the streak of months, record breaking months that started last year in June is continuing and now we are at the 11th month, so that's one thing and that's true for the global mean average, it is also true for sea surface temperature."

Copernicus, the EU's climate change agency, released data indicating that April 2024 was the hottest on record globally. The surface air temperature averaged 15.03 Celsius, surpassing the April average calculated between 1991 and 2020 by 0.67 degrees. Moreover, this temperature was 1.58% higher than the preindustrial reference point set at the Paris climate summit.
