It follows the hottest June ever recorded, marking one of the hottest summers in recent history.
Heat warnings slammed much of the eastern half of the USA - from Kansas to OH and North Carolina to New Hampshire - last month.
This graph illustrates the global land and ocean temperatures during the month of July dating back to 1880.
July 2019 is now officially the hottest month on record, since record-keeping began 140 years ago.
According to the NOAA, the average global temperature in July was 0.95 degrees Celsius (1.71 degrees Fahrenheit) above the 20th century average of 15.8 degrees Celsius (60.4 Fahrenheit), making it the hottest July in its records, which go back to 1880. Parts of the Pacific, Indian and Atlantic Oceans are also showing record highs. A punishing heat wave swept across Europe and then settled over Greenland, where it triggered hundreds of billions of tons of ice melt. Last month also saw a record low for average Arctic and Antarctic sea ice coverage (19.8% below average).
The NOAA report also explained that July's extreme heat caused other historic changes on the planet, as average Arctic sea ice was nearly 20% below the July average, beating than the previous historic low of July 2012.
Because July is generally the warmest month on the calendar, meteorologists say this means it also set a new all-time monthly record for the past 140 years.
Berkeley Earth's analysis found that 2019 is unlikely to set a new record for the warmest year, largely because the January through May period was colder than the same period in 2016.
In Canada, there is extra reason to be concerned about this rapid planet heating, as the Canadian government announced earlier this year that Canada was warming at more than twice the average global rate, with the average annual temperature throughout Canada is expected to rise by 3°C by 2055.

According to the United Nations, there hasn't been a strong El Nino this year.
"Human activities-primarily the burning of fossil fuels and deforestation-have caused the atmosphere and ocean to heat up".
