The cryosphere is failing to cooperate with the anthropogenic global warming narrative that says rising greenhouse gas emissions should be catastrophically melting Arctic ice.
Scientists (O’Regan et al., 2021) report Ryder Glacier in north Greenland has advanced 2,881 m from 1948-2015 given its advancing rate of 43 m/yr-1. Its modern ice extent is about 50 km greater than 6,300 years ago.
Nearby, the ~60 km-tongued Petermann Glacier, didn’t even exist during the Roman Warm Period. As the chart on the bottom right of the image below shows, there was no ice in this region for all but a few centuries of the Holocene prior to 2,000 years ago. Petermann’s Little Ice Age size was similar to its modern condition.

Another glaciologist (Winker, 2021) asserts there is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm. The glacier reached its maximum advanced phase during the Little Ice Age, which had CO2 concentrations in the 275 to 280 ppm range.
“The ‘Holocene Thermal Maximum’ or ‘Hypsithermal’ at Jostedalsbreen provides no evidence for any substantial glacial activity and can be characterised as a prolongated period of near (possibly even complete) glacier disappearance… By contrast, the highest glacial input is dated to 600 and 200 cal. a BP indicating the local ‘Little Ice Age’-maximum.”
Interestingly, after wasting away rapidly during the 1930s and 1940s, the glacier stabilized. From the 1950s to 1980s, there was a “slight overall advance” in ice extent. This corresponds to a similar melt pattern for the Nigardsbreen glacier.

Several months ago we highlighted another new study documenting a much warmer-than-today Early and Middle Holocene in East Greenland. Ice caps were “absent” or far less extensive than they are presently during this period.
What may be surprising is that carbon-dated plant remains buried under retreating glaciers in East Greenland affirm these locations were not covered in glaciers as recently as 400 to 500 years ago, or during the Little Ice Age cold period.

The authors even acknowledge there were occasionally brief “cold stages” during the Holocene when Greenland’s glacier extent advanced to today’s levels.
“…Renland Ice Cap briefly reach[ed] extents during cold phases that may have been similar to today.”
Of course, this affirms that modern temperatures and ice volumes fall within the range of a “cold stage” too.
So, once again, there is no evidence to support the alarmist claims that modern glacier extents are unprecedented or even unusual relative to the last 10,000 years – including the last few centuries.

The word some is missing in the headline.

At the very top of a Google of this particular glacier ….

“The processes controlling advance and retreat of outlet glaciers in fjords draining the Greenland Ice Sheet remain poorly known, undermining assessments of their dynamics and associated sea-level rise in a warming climate. Mass loss of the Greenland Ice Sheet has increased six-fold over the last four decades, with discharge and melt from outlet glaciers comprising key components of this loss. Here we acquired oceanographic data and multibeam bathymetry in the previously uncharted Sherard Osborn Fjord in northwest Greenland where Ryder Glacier drains into the Arctic Ocean. Our data show that warmer subsurface water of Atlantic origin enters the fjord, but Ryder Glacier’s floating tongue at its present location is partly protected from the inflow by a bathymetriOc sill located in the innermost fjord. This reduces under-ice melting of the glacier, providing insight into Ryder Glacier’s dynamics and its vulnerability to inflow of Atlantic warmer water.”
I have lived on the same salt water canal for 45 years, yes we have had flooding with moon tides but the water never goes over the bulkhead during normal moon tides. 45 years with no increase in water level so why the hysteria over global warming? People getting rich over this false claim that’s why. Look at Al Gore`s predicting NYC will be under water by 2020, demented liberal press never mentioned just how wrong the moron is.
Is Kennth Richard not able to read the graph he posted to support his phony headline:
The graph posted in the notrickszone (aka low tricks zone) report is showing glacial activities in at the Jostedalsbreen site for close to 9000 years out of the last 11000 years of the Holocene.
Most funny: the vast majority here is not realizing this. OMG
I have a growing collection of papers on interglacial temperatures in addition to the well known Polar ice cores that may be of interest. The IPCC manipulating the data to say no change for 2,000 years to 1850 is obviously deceitful on the basis of these and so may more papers, never mind written history, and archeology appearing from under glaciers. Now what does that tell you? 19 papers here: here: https://www.dropbox.com/s/xffozx2nfpy3sia/Interglacial%20climate%20papers.zip?dl=0
