With a bit of luck Margo and I will be doing a fairly comprehensive video with a discussion on Arctic ice tomorrow.
An update of ice thickness
and volume - 16 July, 2019
Earth just had its hottest June on record, on track for warmest July
Straits Times,
17 July, 2019
WASHINGTON (WASHINGTON POST) - Boosted by a historic heat wave in Europe and unusually warm conditions across the Arctic and Eurasia, the average temperature of the planet soared to its highest level ever recorded in June.
According
to data released on Monday (July 16) by NASA, the global average
temperature was 0.93 degrees C above the June norm (based on a
1951-to-1980 baseline), easily breaking the previous June record of
0.82 deg C, set in 2016, above the average.
The
month was punctuated by a severe heat wave that struck Western Europe
in particular during the past week, with numerous
all-time-hottest-temperature records falling in countries with
centuries-old data sets.
Notably,
13 locations in France surpassed their highest temperature ever
recorded. The heat wave's highest temperature of 45.9 deg C, posted
in Gallargues-le-Montueux, was 3.2 deg C above the old record, set
during an infamous heat wave in July and August 2003.
NASA
is the second institution to confirm that it was Earth's hottest
June, as the Copernicus Climate Change Service had already determined
that June 2019 was the warmest such month on record for Europe and
globally.
June
featured unusually mild conditions in the Arctic, particularly in
Greenland, where the melt season got off to an early start.
July
is picking up right where June left off. Zeke Hausfather, a climate
scientist based in Berkeley, California, tweeted that the month so
far ranks as the hottest on record narrowly ahead of 2017, the
previous record holder.
"If
this July turns out to be the warmest July (it has a good shot at
it), it will be the warmest month we have measured on Earth!"
tweeted Michael Mann, a climate scientist at Pennsylvania State
University.
Like
June, July has featured some notable high-temperature extremes,
including in Nunavut, Canada, the northernmost permanently inhabited
location on Earth. It hit a record high of 21 deg C on Sunday,
breaking the previous record of 20 deg C.
In
addition, Alaska last week posted its hottest two days on record,
highlighted by a temperature of 32.2 deg C in Anchorage for the first
time.
The
June monthly record and July's toasty first half raises the odds that
2019 could make a run for a top-three finish for warmest year, rather
than top five. According to data from NASA and the National Oceanic
and Atmospheric Administration, nine of the 10 warmest years on
record have occurred since 2000, a trend that scientists have tied
mainly to human emissions of greenhouse gases, which scientists say
are trapping extra heat in the atmosphere.

If
the trends of the first half of this month continue, it will beat the
previous record from July 2017 by about 0.025C, according to
calculations by Karsten Haustein, a climate scientist at the
University of Oxford, and others.
This
follows the warmest-ever June, which was confirmed this week by data
from the US space agency Nasa, following Europe’s Copernicus
satellite monitoring system.
