Where calendar winter is underway, unseasonably warm temperatures have made the population feel like it's June rather than January; and where it is summer the temperatures are higher than usual. In short - the global average temperature is at the highest level recorded at the end of January in the recording history, it says The Washington Post.
The intense heat, some 20 to 30 degrees above average, extends south to Australia and South Africa, and north to northern Asia, and is the result of a combination of weather and climate factors, including El Niño.
Climatologist and weather historian Maximiliano Herrera documented the temperature records set in recent days and described them on the X network as "extraordinary", "relentless", "insane" and "endless".
Here's an overview of the highest temperatures around the world, as posted by Herrera:
Western Europe: High temperatures reached up to 20 degrees Celsius. Daily records included 23,3 Celsius in Colobrier, France; 23,2 Celsius in Cuenca, Spain; 17,9 Celsius in Imst, Austria; and 16,4 Celsius in Piota, Switzerland.
The breadth and intensity of winter heat in Europe is reminiscent of a historically warm period just over a year ago.
Australia: High temperatures approached 49C in parts of South Australia and Queensland on Wednesday, including 48,3C in Odnadata and 47,9C in Birdsville.
South America: Temperatures rose as high as 23 degrees on Tuesday, so Trelev, Argentina, had its hottest day on record with a high of 42,6 degrees Celsius. On Monday, Talca in Chile hit its all-time high of 38,8 Celsius on a day that changed South America's climate history, according to Herrera.
In Colombia, Neiva reached 39,2C, the highest January temperature ever recorded there, while Pao de Acucar in the Brazilian state of Alagoas reached 41,2C.
Africa: Record-breaking heat has warmed the region from Liberia to the Congo for weeks. Tuesday's high of 39,6 Celsius in Dimbokro brought the hottest January day in Cote d'Ivoire. In South Africa, Violsdrift jumped 46,1 Celsius.
Asia: Dawei, Myanmar hit 37,0C on Tuesday, breaking its January record for the highest temperature, while the Maldives equaled its hottest January temperature on Wednesday with a high of 33,4C in Hanimaad.
The Caribbean, Mediterranean and Mexico also recorded record warmth for this time of year.
Forecast
Weather models show that warm spells will last at least another week in many places, the Washington Post writes. In Europe, the record heat is expected to spread eastward into central Europe.
A warm start to January could increase Earth's chances for a record-warming 2024. The National Oceanic and Atmospheric Administration said there is a "one in three chance that 2024 will be warmer than 2023 and a 99 percent chance that 2024 will rank among the top five the warmest years."
The World Meteorological Organization is announced on January 12 that the year 2023 is "the hottest ever recorded in history".
This United Nations agency has warned that the average annual temperature has increased by about 1,4 degrees Celsius compared to pre-industrial times.
The WMO warned that, with this trend, the year 2024 could be even hotter and warned of increasingly frequent heat waves, floods, fires and melting glaciers in the future.
