Third-hottest June puts 2017 on track to make hat-trick of hottest years

June 2017 was beaten only by June in 2015 and 2016, leaving experts with little hope for limiting warming to 1.5C or even 2C

Last month was the third-hottest June on record globally, temperature data suggest, confirming 2017 will almost certainly make a hat-trick of annual climate records, with 2015, 2016 and 2017 being the three hottest years since records began.

The figures also cement estimations that warming is now at levels not seen for 115,000 years, and leave some experts with little hope for limiting warming to 1.5C or even 2C.
