Reuters writes that the showcased data was made possible by computer calculations based on information coming from satellites, aircraft and weather stations, among other sources.

Thus, "the month was the warmest June globally at just over 0.5°C above the 1991-2020 average, exceeding June 2019 – the previous record – by a substantial margin", experts warned.

They also said that, while Europe saw record-breaking temperatures, North America, Asia and Eastern Australia also registered higher than normal temperatures in the month of June. Marine ecosystems also suffered due to higher temperatures, as long-term climate change effects and El Nino caused more tropical cyclones and increased rainfall.

Experts at Copernicus said that "exceptionally warm sea surface temperature anomalies were recorded in the north Atlantic...Extreme marine heatwaves were observed around Ireland, the U.K. and in the Baltic Sea."

The ice belt located in the Antarctic seas also saw a 17% decrease in its surface compared to the average, also breaking another June record in this regard.

This year in June, the registered temperature was 0.5 degrees Celsius higher than the average and 0.1 degrees higher than the previous record, noted in 2019.

Since 2012, temperature recordings in June were at least 0.1 degrees higher compared to the average since the year of reference 1991. This means that for over a decade now, we haven't had a month of June where temperatures were the same or lower than the historic average.
