What’s impressive about the warm start to 2020 is the lack of warmth provided by an El Niño.
A record-tying strong El Niño lasted through roughly the first half of 2016, giving a boost to global temperatures.
This year, we may instead be trending toward a La Niña. NOAA’s latest monthly outlook indicated a roughly 50/50 chance La Niña may develop by fall.
Parts of Asia, Scandinavia, western Europe, Mexico, the south Atlantic Ocean and western Pacific Ocean were record warm over the first six months of 2020, according to NOAA.
France had its warmest first half of any year in records dating to 1900, according to Météo-France.
By far, the most extreme temperature anomalies anywhere on the planet in 2020 have been in parts of Russia.
On June 20, a Russian city just north of the Arctic Circle reached 100 degrees Fahrenheit. Ten days later, a city farther north along Russia’s Arctic coast soared to 93 degrees. These may be the farthest north 90s or 100s on record in the Arctic.
The unusually warm spring sent snow cover plummeting in the Siberian Arctic starting in May, and sapped soil moisture later in the month, according to an analysis from Europe’s Copernicus Climate Change Service (C3S).
For the second summer in a row, intense wildfires raged across Siberia. Arctic sea ice coverage along the coast of Siberia plunged to a 41-year record low for June.
One of the Warmest Junes
June 2020 tied Earth’s warmest June in at least 141 years of temperature records, according to a separate analysis also released Monday.
NASA’s Goddard Institute for Space Studies found that June 2020 global temperatures were 0.93 degrees Celsius above the 1951-1980 average, tying 2019 for the warmest June in their records dating to 1880.
June was the 13th consecutive month in the top two warmest respective months in NASA’s database, a streak that began in June 2019.
Four of the first six months of 2020 either tied or set new records for that month in NASA’s analysis.
