Some statistics from NOAA:
The June temperature across global land and ocean surfaces was 1.62°F (0.90°C) above the 20th century average of 59.9°F (15.5°C). This was the highest for June in the 1880–2016 record.
The average Arctic sea ice extent for June was 530,000 square miles (1.37 million square kilometers) below average, which is roughly twice the area of Texas. This is 11.4% below the 1981–2010 average and was the smallest June extent since satellite records began in 1979.
The year-to-date temperature across global land and ocean surfaces was 1.89°F (1.05°C) above the 20th century average of 56.3°F (13.5°C) . This was the highest for January-June in the 1880–2016 record.
NOAA anomalies are calculated from a 20th century baseline. As the global conversation focuses on a goal of limiting warming to 2°C above pre-industrial levels, we have combined the NOAA and NASA global temperature numbers and adjusted them to an early industrial baseline of 1881-1910 to better gauge our warming against this global goal. This is reflected in the enclosed graphic.
