July was the hottest month on record on Earth, officials in the US have said.
The average temperature last month was 16.58C, beating the previous global mark set in 1998 and 2010.
Records go back to 1880, but nine of the 10 hottest months on record have happened since 2005.
The first seven months of this year were the hottest January-July span on record. Climate scientist Jake Crouch, from the US National Oceanic and Atmospheric Administration, said it is likely that 2015 will be the hottest year on record, beating last year.
Mr Crouch said this reaffirms that the Earth is warming, with a boost this year from an El Nino warming of the Pacific Ocean.
