But we do know this.

“This is the new normal,” said Gavin A. Schmidt, director of the Goddard Institute for Space Studies, the NASA group that conducted the analysis. But, he said, “It’s also changing. It’s not that we’ve gotten to a new plateau — this isn’t where we’ll stay. In ten years we’re going to say ‘oh look, another record decade of warming temperatures.’”

Global Analysis May 2017
Two of the world's hottest spots:
Spain's May 2017 national temperature of 19.0°C (66.2°F) was 2.4°C (4.3°F) above the 1981–2010 average and the second highest May temperature since 1965, behind the record year of 2015. 
The May 2017 average temperature across the United Kingdom was 12.1°C (53.8°F) or 1.7°C (3.1°F) above the 1981–2010 average. This was the second highest May temperature since national temperature records began in 1910, behind 2008. Regionally, England, Wales, Scotland, and Northern Ireland had a top third warm May on record.
