The world's average temperature in July 'was the second highest on record'
The July temperature across global land and ocean surfaces was 0.83 degrees Celsius above the 20th century average of 15.8 degrees Celsius, the National Oceanic and Atmospheric Administration (NOAA) said.
The NOAA global temperature dataset record dates back 138 years to 1880. The temperature is the second highest value for July during that period. The highest was recorded in 2016, NOAA said.
The agency also said July 2017 marked he 41st consecutive July and the 391st consecutive month with temperatures at least nominally above the 20th century average.
Nine of the 10 warmest Julys on record have occurred during the 21st century, NOAA added. Only one year from the 20th century (1998) is among the top 10 warmest Julys on record.
The summary of weather data also provided details about average Arctic and Antarctic sea ice extent, saying it was 16.1 percent and 4.5 percent below the 1981-2010 average respectively in both polar regions.
The summary was developed by scientists at NOAA as a services to government, business, academia and the public to support informed decision-making on climate matters.
