to new global data released by NOAA's National Centers for
Environmental Information.



FULL STORY ==========================================================================
July 2021 has earned the unenviable distinction as the world's hottest
month ever recorded, according to new global data released today by
NOAA's National Centers for Environmental Information.

"In this case, first place is the worst place to be," said NOAA
Administrator Rick Spinrad, Ph.D. "July is typically the world's warmest
month of the year, but July 2021 outdid itself as the hottest July and
month ever recorded. This new record adds to the disturbing and disruptive
path that climate change has set for the globe." July 2021 by the numbers
* Around the globe: the combined land and ocean-surface temperature
was
1.67 degrees F (0.93 of a degree C) above the 20th-century average
of 60.4 degrees F (15.8 degrees C), making it the hottest July
since records began 142 years ago. It was 0.02 of a degree F (0.01
of a degree C) higher than the previous record set in July 2016,
which was then tied in 2019 and 2020.

* The Northern Hemisphere: the land-surface only temperature was the
highest ever recorded for July, at an unprecedented 2.77 degrees
F (1.54 degrees C) above average, surpassing the previous record
set in 2012.

* Regional records: Asia had its hottest July on record, besting the
previous record set in 2010; Europe had its second-hottest July
on record -- tying with July 2010 and trailing behind July 2018;
and North America, South America, Africa and Oceania all had a
top-10 warmest July.

Extreme heat and global climate change With last month's data, it remains
very likely that 2021 will rank among the world's 10-warmest years on
record, according to NCEI's Global Annual Temperature Rankings Outlook.

Extreme heat detailed in NOAA's monthly NCEI reports is also a reflection
of the long-term changes outlined in a major report released this week
by the Intergovernmental Panel on Climate Change.

"Scientists from across the globe delivered the most up-to-date
assessment of the ways in which the climate is changing," Spinrad said
in a statement. "It is a sobering IPCC report that finds that human
influence is, unequivocally, causing climate change, and it confirms
the impacts are widespread and rapidly intensifying." Other notable
highlights from NOAA's July global climate report
* Sea ice coverage varied by hemisphere: The Arctic sea ice coverage
(extent) for July 2021 was the fourth-smallest for July in the
43-year record, according to analysis by the National Snow and
Ice Data Center.

Only July 2012, 2019 and 2020 had a smaller sea ice
extent. Antarctic sea ice extent was above average in July --
the largest July sea ice extent since 2015 and the eighth highest
on record.

* The tropics were busier than average: In the Atlantic basin,
the season's
earliest fifth-named storm, Elsa, formed on July 1. The Eastern
North and Western Pacific basins each logged three named
storms. Overall, global tropical cyclone activity this year
so far (through July) has been above- normal for the number of
named storms.
