Global temperatures in July 2017 tied for the warmest on record for any July in 137 years of record-keeping, according to data released Tuesday by NASA's Goddard Institute for Space Studies.

NASA said July 2017 temperatures across all land and ocean surfaces were 0.83 degrees Celsius above the 1951-1980 average. That technically nudges out July 2016 by 0.01 degrees Celsius as Earth's warmest July, but since that margin is so small, NASA said it was statistically a tie.

July 2017 equaled last July despite 2016 global temperatures being boosted by a strong El Niño event early that year.

A separate report released Thursday by NOAA found July 2017 was only 0.05 degrees Celsius cooler than the previous July, but was still the second-warmest in its 137-year database. Land temperatures, according to the NOAA report, were the hottest they've ever been in 1,651 months of record-keeping, dating back to 1880.

NOAA's analysis found record July warmth in parts of southern Africa, the Arabian Peninsula, China, Australia and the southern Indian Ocean. It was the hottest July on record in Bahrain and the third-hottest ever in Australia in over 100 years of records, NOAA's report said.

Meanwhile, parts of northern Europe, northern and eastern Russia and eastern Canada were cooler than average in July, according to NOAA.

The first five months of 2017 all individually ranked as the second-warmest on record in NASA's database ; only 2016 was warmer through May. June 2017 ended that trend, finishing as the fourth-warmest June.

July also marked 384 months since the last colder-than-average month in NASA's database – July 1985.

July is typically the warmest month of the year globally because the Northern Hemisphere has more land masses than the Southern Hemisphere. Land can heat faster and further than the ocean, so the Southern Hemisphere cannot warm as easily during their summer.

A separate analysis by the Japanese Meteorological Agency found July 2017 was the second-warmest July in its database. July 2016 was still warmer, by 0.02 degrees Celsius.

The last three consecutive years – 2014, 2015 and 2016 – each set a new global record for warmth, according to NOAA.

What's ultimately most important is not whether a given month is a fraction of a degree warmer or colder; rather, it's the overall trend, which continues its upward climb since the late 1970s .
