Using data from the Danish Meteorological Institute (DMI), Japanese skeptic blogger Kirye just tweeted how Arctic sea ice volume has surged to the 3rd highest level in 16 years.

According to DMI, average Arctic sea ice extent in July is at its highest level since 2005.
With temperatures at normal levels, there is little prospect of Peter Wadhams predictions coming true this year!

Recently climate catastrophe non-believers have been pointing out that Arctic sea ice volume has been gaining over the past years and has not trended downward for some dozen years now.
And global warming alarmists have been very silent on the subject of climate change now that global surface temperatures have cooled and Arctic and Greenland snow and ice have rebounded.
Embarrassed, they don’t want to be reminded of all the absurd predictions they made 10 years ago, with some as recently as just five years ago.

Arctic sea ice volume melt rates have started to slow, with ice volume 4th highest since 2003.
Temperatures near the pole have been below normal almost every day this summer.

Lately Arctic sea ice volume has been a topic which climate skeptics have been looking at quite closely.
According to Al Gore and a number of climate ambulance chasers, Arctic sea ice in late summer should have long disappeared by now, see here..
But then just a few years after, the Arctic sea ice area began to recover from its lows of 2007 and 2012. So immediately alarmists shouted that area was not really what mattered, but rather sea ice volume is what really counted. Okay, that made perfect sense. Mass is in fact what’s important, and not area, when worrying about polar ice disappearing …

German climate and weather analyst “Schneefan” (Snow Fan) here writes a summary of the first half of 2018 thus far. All data show that the surface temperature of the globe has been cooling strongly over the past months and polar ice mass growing.
He writes that in the first half of this year we have seen weak solar activity and La Nina conditions acting to cool the globe’s surface. Moreover Arctic and Antarctic ice mass have grown in comparison to the previous years. …

As we all know, Greenland is warming up rapidly, causing the ice sheet to melt faster and faster.
Well, according to the BBC and New York Times, at least.
Only one slight problem – the temperature record shows quite a different story.
Each year, the DMI publishes the Greenland – DMI Historical Climate Data Collection:

A group of scientists at the University of Rhode Island stumbled on something unexpected when analyzing data brought back from a 2014 expedition to western Antarctica.
Scientists found an abundance of the noble gas Helium-3, indicating there is a volcanic heat source beneath the Pine Island glacier — the fastest melting glacier in the South Pole. The findings were published in a study in the journal Nature Communications.
“When you find helium-3, it’s like a fingerprint for volcanism. We found that it is relatively abundant in the seawater at the Pine Island shelf,” chemical oceanographer Brice Loose, the study’s lead author, said in a statement.

Antarctic ice sheet is melting, but rising bedrock below could slow it down
An international team, led by DTU Space at the Technical University of Denmark with Colorado State University, has found that the bedrock below the remote West Antarctic Ice Sheet is rising much more rapidly than previously thought, in response to ongoing ice melt.
The study, “Observed rapid bedrock uplift in the Amundsen Sea Embayment promotes ice-sheet stability,” reveals new insights on the geology of the region and its interaction with the ice sheet and is published in the journal Science. The authors noted that the findings have important implications in understanding and predicting the stability of the ice sheet and Earth’s rising sea levels.

From the “skating on thin ice” department.
According to a new paper published in the Journal of Geophysical Research, the observed mean thickness of the sea ice in the region north of (Arctic) Svalbard was substantially thinner (0.94 m) in 1955 than it has been in recent years (~1.6 m, 2015/2017).

A new paper about to be in press, comes at the end of a flurry of papers and reports published this week that claims Antarctica was losing ice mass. Zwally says ice growth is anywhere from 50 gigatons to 200 gigatons a year. NASA glaciologist Jay Zwally says his new study will show, once again, the eastern Antarctic ice sheet is gaining enough ice to offset losses in the west.

Arctic sea ice volume is the highest for the date in 13 years, and melt is the slowest on record.

According to the Danish Meteorological Institute, Arctic sea ice volume is highest for the past eleven years and above the fifteen year mean since the start of DMI records in 2003.

The Global Environment and Marine Department of the Japanese Meteorological Agency recently corrected the long term trend in the annual mean sea ice extent in the Antarctic area: from 0.015 x 106 km2per year to 0.019 x 106 km2 per year on 11 May 2018.
That’s more than a 25% adjustment (15,000 sq. km to 19,000 sq km). So while chunks the size of Manhattans may break off from time to time, about 300 Manhattans of new ice gets added annually.
The report notes that in the Antarctic Ocean: “the annual maximum and annual mean sea ice extents have shown a long-term trend of increase since 1979”.
by Lovell, A.M. et al., 2017 in CO2Science, May 24, 2018
In describing their findings, Lovell et al. state that “between 1972 and 2013, 36% of glacier termini in the entire study area advanced and 25% of glacier termini retreated, with the remainder showing no discernible change outside of the measurement error (± 66 m or ± 1.6 m yr-1) and classified as ‘no change'” (see figure below). Although there were some regional differences in glacier termini changes, these regions over the last four decades were more closely linked to non-climatic drivers, such as terminus type and geometry, than any obvious climatic or oceanic forcing.”
