Key Greenland glacier growing again after shrinking for years​

A major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, a new NASA study finds.

The Jakobshavn (YA-cob-shawv-en) glacier around 2012 was retreating about 1.8 miles (3 kilometers) and thinning nearly 130 feet (almost 40 meters) annually. But it started growing again at about the same rate in the past two years, according to a study in Monday’s Nature Geoscience. Study authors and outside scientists think this is temporary.​

Yeah, we all see it coming as the normal solar cycles go the other way........

The Leftards will flip and call it Global Freezing in the coming years......."Totally caused by man"

Of course they do.

NASA's Oceans Melting Greenland (OMG) project has revealed Greenland’s Jakobshavn Glacier, the island’s biggest, is actually growing, at least at its edge. In research published Monday in Nature Geoscience, researchers report that since 2016, Jakobshavn’s ice has thickened slightly, thanks to relatively cool ocean waters at its base—which have caused the glacier to slow down its melt. This reverses the glacier’s 20-year trend of thinning and retreating. But because of what else is happening on the ice sheet, and the overall climate outlook, that’s not necessarily a good thing for global sea level.

That's because, despite the fact that this particular glacier is growing, the whole Greenland ice sheet is still losing lots and lots of ice. Jakobshavn drains only about seven percent of the entire ice sheet, so even if it were growing robustly, mass loss from the rest of the ice sheet would outweigh its slight expansion.


The idiots have taken localized events sand pretend they are Global.

Oh

As I posted in the other thread-

Of course it is, due to cycles-

The research team combined earlier data on ocean temperature with data from the OMG mission, which has measured ocean temperature and salinity around the entire island for the last three summers. They found that in 2016, water in Jakobshavn's fjord cooled to temperatures not seen since the 1980s.

"Tracing the origin of the cold waters in front of Jakobshavn was a challenge," explained Ian Fenty of JPL, a co-author of the study. "There are enough observations to see the cooling but not really enough to figure out where it came from." Using an ocean model called Estimating the Circulation and Climate of the Ocean (ECCO) to help fill in the gaps, the team traced the cool water upstream (toward the south) to a current that carries water around the southern tip of Greenland and northward along its west coast. In 2016, the water in this current cooled by more than 2.7 degrees Fahrenheit (1.5 degrees Celsius).

Although the last few winters were relatively mild in Greenland itself, they were much colder and windier than usual over the North Atlantic Ocean. The cold weather coincided with the switch in the NAO climate pattern. Under the influence of this change, the Atlantic Ocean near Greenland cooled by about 0.5 degrees Fahrenheit (1 degree Celsius) between 2013 and 2016. These generally cooler conditions set the stage for the rapid cooling of the ocean current in southwest Greenland in early 2016. The cooler waters arrived near Jakobshavn that summer, at the same time that Jakobshavn slowed dramatically.

The team suspects that both the widespread Atlantic cooling and the dramatic cooling of the waters that reached the glacier were driven by the shift in the NAO. If so, the cooling is temporary and warm waters will return when the NAO shifts to a warm phase once again.

......
The North Atlantic Oscillation (NAO) is a periodic variation in the strengths and positions of the Icelandic Low and the Azores High. The Icelandic Low is a semi-permanent low pressure area sitting close to Iceland, while the Azores (Bermuda) High is a semi-permanent high near the Azores. The Icelandic Low and Azores High fluctuate in strength and position over a period of months and years, and their variations can have an effect on weather in the eastern United States by shifting the location of the jet stream which affects temperature and precipitation patterns over the southeastern United States. The fluctuations vary in their duration and strength from one swing to the next, which makes them difficult to use in detailed climate predictions.

Read the bottom line, crick. Let that soak in.

 

[Crick]

I don't recall having claimed the NAO was a warming indicator. I tend to use thermometers for that. If you'd like to talk about glaciers from a global - therefore more meaningful - stance... Retreat of glaciers since 1850 - Wikipedia

 

[skookerasbil]

Boring topic in here for 10 years.....some shrinking.....some growing.....since forever.

 

[Crick]

Way more shrinking then growing

The world was formed in 1960?

But the narrative from you guys for a long time was all melt all the time.....until people started picking up on the fakery.

Hey....it was you guys that used the term "global".....until it looked st00pid so you changed the narrative.

Ghey

 

[Crick]

No, it wasn't. How many times have you tried to use a snow as proof that the world wasn't getting warmer? There are lots of places on Earth that will get cold and have snow and ice but the planet as a whole is doing this:

But most people think that these mega snows means the idea of global warming is a farce. The science isnt mattering because as long as people are seeing snow and bitter cold temps, they dont worry a wit about climate change.

How do we know that with certainty?

Because for 20 years, there has been zero climate change action. People might be concerned.....but not that much. Only alarmists, who tend to the hysterical anyway, are really concerned = a sliver of the population. SLiVeR

Any response you might have looks only like an opinion of some climate crusader in the middle of the nether-regions of the internet. What I said above carries tons and tons of evidence and is not debatable.

But we'll let the viewers decide....

Then there's this bit of data. In 1942, a squadron of 8 military aircraft, including 6 P-38 fighters had to crash land on the Greenland ice sheet. In 1988 one of the P38 fighters was found 260 feet below the surface of the ice. By the time it was exhumed in 1992 it was under 268 feet of ice.

Last year, another one of the P-38s was located under 340 feet of ice. That's 72 feet of ice accumulation over the last 26 years.

You know, because of global warming.

No, it wasn't. How many times have you tried to use a snow as proof that the world wasn't getting warmer? There are lots of places on Earth that will get cold and have snow and ice but the planet as a whole is doing this:

What exactly do you think a chart of a temperature data base that is as heavily manipulated, massaged, homogenized, and infilled as that one proves? Other than that climate science is wiling to engage in fraud if that is what it takes in order to support the alarmist narrative?

Look at regional temperature records from around the globe and see if you can spot the disconnect between regional temperatures and the contrived global temperature...

You gotta admit though.....pretty brilliant scam. But that whole switch from global warming to climate change sure did raise lots of eyebrows

 

[Crick]

There was no "switch" from global warming to climate change. The only eyebrows ever raised were those of deniers who've attempted for years to capitalize on the two terms to sell their paranoid fantasies.

But, back on topic. Here is the abstract of the study, published in Nature Geoscience, that found parts of the glacier to be slowing and thickening.
Interruption of two decades of Jakobshavn Isbrae acceleration and thinning as regional ocean cools

Abstract
Jakobshavn Isbrae has been the single largest source of mass loss from the Greenland Ice Sheet over the last 20 years. During that time, it has been retreating, accelerating and thinning. 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 concurrent cooling of ocean waters in Disko Bay that spill over into Ilulissat Icefjord. Ocean temperatures in the bay’s upper 250 m have cooled to levels not seen since the mid 1980s. Observations and modelling trace the origins of this cooling to anomalous wintertime heat loss in the boundary current that circulates around the southern half of Greenland. Longer time series of ocean temperature, subglacial discharge and glacier variability strongly suggest that ocean-induced melting at the front has continued to influence glacier dynamics after the disintegration of its floating tongue in 2003. We conclude that projections of Jakobshavn’s future contribution to sea-level rise that are based on glacier geometry are insufficient, and that accounting for external forcing is indispensable.

Jakobshavn is the largest glacier in Greenland and has been viewed for years now as a "ticking timebomb" with respect to its potential to cause catastrophic sea level rise. As noted in the abstract, the cause of the partial reversal is held to be rather dramatically cooling deep water caused by a cycle unrelated to global warming which will warm again in the not-too-distant future. This finding only strengthens the contention that glacier dynamics are heavily controlled by water temperature and currents at their fronts.

In an interview with NBC News, Josh Willis, the study's lead scientist said "“In the long run we’ll probably have to raise our predictions of sea level rise again,”
