The June 2021 global surface temperature was the fifth highest for June in the 142-year record at 0.88°C (1.58°F) above the 20th century average, NOAA, the U§ meteorological service reported this week.
Only Junes of 2015 (fourth warmest), 2016 (second warmest), 2019 (warmest), and 2020 (third warmest) were warmer and had a global temperature departure above +0.90°C (+1.62°F), it said in a statement. Nine of the 10 warmest Junes have occurred since 2010.
June 1998 is the only June from the previous century among the 10 warmest Junes on record, and currently ranks as the tenth warmest June on record.
June 2021 also marked the 45th consecutive June and the 438-consecutive month with temperatures, at least nominally, above the 20th century average.
NOAA portrays the June temperature across its records thus:
Much of the globe experienced warmer-than-average conditions, with temperature departures of at least +3.0°C (+5.4°F) across large portions of the Northern Hemisphere land, specifically across parts of North America, Europe, and western and central Russia.
The Record-warm June temperatures encompassed 4.18% of the world's surface. This was the sixth highest June percentage since records began in 1951.
The global land-only surface temperature for June 2021 was the highest on record at 1.42°C (2.56°F) above average. This value surpassed the previous record set in 2019 by +0.11°C (+0.20°F).
The ten warmest June global land-only surface temperatures have occurred since 2010. The unusually warm June global land-only surface temperature was mainly driven by the very warm Northern Hemisphere land, which also had its highest June temperature departure at +1.69°C (+3.04°F). The now second highest June temperature for the Northern Hemisphere occurred in 2012 (+1.51°C / +2.72°F).
on a year to date basis for the calendar first haf, the global surface temperature was 0.79°C (1.42°F) above average and was the eighth warmest such period since global records began in 1880.
Looking ahead, the year 2021 is very likely to rank among the ten warmest years on record, according to a statistical analysis done by NCEI scientists.
