Two recent reports, released by NASA and the US National Climate Data Centre, have confirmed that last month was the warmest June since records began.
June was the fourth consecutive month that had broken temperature records, the US National Oceanic and Atmospheric Administration (NOAA) said. Global monthly records were also broken in March, April and May.
June was the 304th month in a row that recorded a global average temperature higher than the 20th century average. February 1985 was the last month temperatures fell below the average.
