Earth just experienced its hottest February on record, with average global temperatures rising 1.77 degrees Celsius above the pre-industrial average for the same month, according to a preliminary report from the European Union's Copernicus Climate Change Agency (C3S). This marks the ninth consecutive month of record high heat.
“While this may seem surprising, it is actually not surprising because continued warming of the climate system will inevitably lead to new temperature extremes.” carlo buontempo C3S said in a statement.
Europe experienced an especially unusually hot month, with average temperatures 3.3 degrees Celsius above the monthly average from 1991 to 2020. Conditions were unusual, with hot and dry weather causing fires in the Americas, including the deadliest wildfire in Chile's history. Most of the rest of the world's land is warm.
The ocean heat is even more extreme, with February's global average sea surface temperature higher than August 2023, making it the ocean's hottest month on record. The average sea surface temperature of 21.09°C recorded in a single day at the end of February was the highest daily temperature on record, and the amount of sea ice in both the Arctic and Antarctic was below average.
richard allan Researchers from the University of Reading in the UK say the record heat on both land and oceans is mainly due to rising concentrations of greenhouse gases in the atmosphere and the warming effects of the El Niño climate pattern in the Pacific Ocean. ing. Fewer reflected aerosols due to reduced air pollution also contributed to the heat in some areas, he said.
Latest information suggests that last year's record-breaking El Niño, which began in June 2023, could weaken and be replaced by a cooler La Niña by the middle of this year. projection According to the National Oceanic and Atmospheric Administration. But that may not bring instant respite. Historically, the year following an El Niño event bears the brunt of its heating effects.
