The first half of 2017 is the second warmest in the historical record that dates back to 1880, trailing only last year's high mark, the National Oceanic and Atmospheric Administration said in data released Tuesday. It was the third-warmest June on record. So far, the average global temperature this year is 1.64°F above the 20th-century average of 56.3°F, according to the federal statistics.
June 2017 marks the 41st consecutive June and the 390th consecutive month with temperatures at least nominally above the 20th century average," NOAA said in its latest monthly report.
