The announcement was made by the US agency for the atmosphere and oceans (NOAA).

The global average of 16.55 ºC in June was 1.05 ºC above the 20th century average. This was the first time that a monthly average was more than one degree above normal temperature, according to NOAA.

Other climate monitoring systems, such as NASA, Berkeley Earth and the European Copernicus, had already pointed out that last June had been the hottest since there was a record, but NOAA is considered the standard of records, with data that goes back to 1850.

The increase in the last month of June is "a considerable leap", because normally the global monthly records have such a broad base of information collection that they allow to detect variations of hundredths of a degree, and not just of tenths, stressed the climate scientist from the NOAA, Ahira Sanchez-Lugo.

"The recent temperature recorded, as well as the extreme fires, pollution and flooding we are seeing this year are what we would expect to see in a warm climate," said Cornell University climate scientist Natalie Mahowald. “We are just getting a small taste of the type of impacts that are expected with climate change”, she reinforced.
