Seems like the ‘carbon dioxide control knob’ has gone wonky. Alarmists must wonder: how can that be?

It appears that Iceland won’t have to be renamed Tepidlandia anytime soon, says Larry Bell.

According to researchers at the University of Iceland, each of the country’s glaciers will expand this year for the first time in the past 25 years.

As reported in Electroverse, the Hofsjökull, Langjökull, Mýrdalsjökull, and Vatnajökull glaciers have expanded over the last twelve months, from autumn to autumn, “With Mýrdalsjökull showing a really significant addition of ice this year.”

These are the largest glaciers in Iceland: Hofsjökull is third largest after Vatnajökull and Langjökull, while Mýrdalsjökull is the country’s fourth largest ice cap.

The research study project manager, Finnur Pálsson, observed that he regarded the reversal to be “unusual.” He noted that Langjökull had been losing around one and a half meters of ice per year for the past 20 years, “but in the last few years he has been close to zero, that is, he has neither expanded nor diminished. And that applies to this year, both for Vatnajökull and Langjökull as well.”

So why is this happening?

Careful to avoid a politically-incorrect narrative contradicting “global warming” mantra, Pálsson simply observed, “It is a fact that it has been colder the last few years. And there was more snowfall in August on the upper part of Langjökull, which is very unusual.”

Well maybe not quite so unusual after all.

As I recently reported in my April 22 column, Jakobshavn — the previously fastest-flowing, fastest-thinning glacier on Greenland’s west coast — has reversed course as well.

Jakobshavn has represented the largest source of Greenland’s ice mass loss over the last 20 years, and has produced about 10 percent of the country’s icebergs.

A study published in the March issue of the journal Nature stated, “Here we use airborne altimetry and satellite imagery to show that since 2016, Jakobshavn has been re-advancing, slowing and thickening. We link these changes to current cooling in ocean waters in Disko Bay that spill over into Ilulissat Icefjord. Ocean temperatures in the bay’s upper 250 meters have cooled to levels not seen since the mid-1980s.”

Again, scientists registered surprise. As reported in Live Science, lead study researcher Ala Khazendar at NASA’s Jet Propulsion Laboratory said, “At first we didn’t believe it. We had pretty much assumed that Jakobshavn would just keep going on as it had over the last 20 years.”

A short sojourn into Greenland’s temperature history might have provided an obvious clue.

The reason that Jakobshavn isn’t shrinking is very likely is due to an entirely natural periodic warm-cold phase shift in the North Atlantic Oscillation (NAO) which occurs in the northern Atlantic Ocean every 20 or 30 years.

Nevertheless, a study reported in the May 2012 issue of the journal Science observed that individual Greenland glaciers expand and contract for complex reasons. Observations of 200 glaciers between 2000-2010 revealed behaviors that varied both in location and time.

Glaciers with growth rates found to be accelerating during a few years, decelerated in others. Some accelerating glaciers were in proximity to others that were decelerating.
