Last month was the second warmest June on record, according to global surface temperature data from NASA’s Goddard Institute for Space Studies.
This year’s global average of 14.67 °C for June falls just short of the 14.74 °C record set in June 1998 — a record aided by a strong, warming El Niño event.
In contrast, this year’s June temperature occurred during a mild La Niña, which tends to have a cooling effect.
