The hot January, without an El Nino impact, provides more robust evidence to the fact of global warming.
January 2020 was the hottest in the 141-year global climate record, according to scientists at the U.S. National Oceanic and Atmospheric Administration (NOAA).
The January global land and ocean surface temperature was 1.14 degrees Celsius above the 20th-century average, surpassing the record set in January 2016. Also, the temperature departure from average was the highest monthly departure ever recorded without an El Nino present in the tropical Pacific Ocean, announced the NOAA in a statement on Thursday.
El Nino is an irregularly occurring climatic change affecting the equatorial Pacific region, characterized by the appearance of unusually warm water off northern Peru and Ecuador. The hottest January without an El Nino impact provides more robust evidence to the fact of global warming.
January 2020 marked the 44th consecutive January and the 421st following month with temperatures, at least nominally, above the 20th-century average. The ten warmest Januaries documented in the climate record have all occurred since 2002.
The year 2020 is very likely to rank among the five warmest years on record, according to U.S. National Centers for Environmental Information scientists.
The Arctic sea ice extent was 5.3 percent below the 1981 to 2010 average, tying with 2014 as the eighth-smallest January extent in the 42-year record, while the Antarctic sea ice coverage during January was 9.8 percent below the average and tied with January 2011 as the 10th smallest, according to the NOAA.
