Monthly reports from the European Union’s Copernicus Climate Change Agency and the National Oceanic and Atmospheric Administration (NOAA) confirm an unusual temperature trend that began in mid-2023, the warmest year on record.
The WMO’s Global Climate Status Report 2023, to be released on March 19, will detail last year’s key climate change indicators and impacts.
The month as a whole was 1.77C warmer than the estimated February average for the pre-industrial reference period 1850-1900, according to the European Center for Medium-Range Weather Forecasts’ Copernicus Climate Change Service.
According to the report, the global average sea surface temperature from 60°S to 60°N in February was 21.06°C, the highest for any month in the ERA5 dataset, and the previous record set in August 2023 (20.98°C). ) exceeded.
According to the ERA5 dataset, the average daily sea surface temperature reached an absolute maximum of 21.09°C at the end of February. Sea surface temperature is defined in the Earth’s outer polar oceans, from 60°S to 60°N, and is used as a standard diagnostic for climate monitoring.
Although El Niño continues to weaken in the equatorial Pacific, ocean temperatures generally remain at unusually high levels.
Temperatures in February were warmer than average in most of the Arctic, Americas, Africa, Europe, and Australia, but much cooler than average in parts of Greenland, East Asia, and Antarctica. A separate report from the National Oceanic and Atmospheric Administration (NOAA) said North America, South America and Europe had the warmest February on record, while Africa had the second warmest.
Global sea ice extent was the fourth smallest in 46 years of record. According to NOAA, the extent of Arctic sea ice was slightly below average, while the extent of Antarctic sea ice was well below average (370,000 square miles/958,295 square kilometers), making it the second smallest on record.
WMO’s Global Climate Situation report uses six international datasets, including ERA5 and NOAA’s National Center for Environmental Information.
