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.
“That was kind of a surprise. We kind of got used to a runaway system,” said Geological Survey of Denmark and Greenland ice and climate scientist Jason Box. “The good news is that it’s a reminder that it’s not necessarily going that fast. But it is going.”
Box, who wasn’t part of the study, said Jakobshavn is “arguably the most important Greenland glacier because it discharges the most ice in the northern hemisphere. For all of Greenland, it is king.”
A natural cyclical cooling of North Atlantic waters likely caused the glacier to reverse course, said study lead author Ala Khazendar, a NASA glaciologist on the Oceans Melting Greenland (OMG) project. Khazendar and colleagues say this coincides with a flip of the North Atlantic Oscillation — a natural and temporary cooling and warming of parts of the ocean that is like a distant cousin to El Nino in the Pacific.
The water in Disko Bay, where Jakobshavn hits the ocean, is about 3.6 degrees cooler (2 degrees Celsius) than a few years ago, study authors said.
While this is “good news” on a temporary basis, this is bad news on the long term because it tells scientists that ocean temperature is a bigger player in glacier retreats and advances than previously thought, said NASA climate scientist Josh Willis, a study co-author. Over the decades the water has been and will be warming from man-made climate change, he said, noting that about 90 percent of the heat trapped by greenhouse gases goes into the oceans.
“In the long run we’ll probably have to raise our predictions of sea level rise again,” Willis said.
Like an escalator
Think of the ocean temperatures near Greenland like an escalator that’s rising slowly from global warming, Khazendar said. But the natural North Atlantic Oscillation sometimes is like jumping down a few steps or jumping up a few steps. The water can get cooler and have effects, but in the long run it is getting warmer and the melting will be worse, he said.
Four outside scientists said the study and results make sense.
University of Washington ice scientist Ian Joughin, who wasn’t part of the study and predicted such a change seven years ago, said it would be a “grave mistake” to interpret the latest data as contradicting climate change science.
What’s happening, Joughin said, is “to a large extent, a temporary blip. Downturns do occur in the stock market, but overall the long term trajectory is up. This is really the same thing.” (VOA)

Life was moving at a fast pace for most of us and then the pandemic hit. The pace definitely slowed down and gave us an opportunity to look back at our lifestyle, routine and our most cherished old memories. 'Looking back' through your old photos on a phone versus flipping through a glossy photo album and reliving each memory? Getting teary eyed at some, and straight up howling with laughter at some others.
Today, advancement in technologies has opened up an ocean of possibilities. So how does one hold on these closest moments and memories in a thoroughly tangible way? Sachin Kataria, CEO, Zoomin shares all the minute details to make festive season personal.
Moving from gifts to personal stories: Gifts are no longer just confined to material items of a certain 'price tag'. Gifting someone is now seen as a chance to create a unique experience and splash of emotions that the receiver can enjoy for years to come. It's a fact that preserving memories is now a lot easier with delivery partners that can convert digital memories into actual personalised frames, albums and a host of memorabilia. And this makes it so much easier and quicker for you to hold meaningful memories close to your heart.

Reframing moments of joy: It isn't always possible to create a photo album or a photo frame of all your special moments or even gift them all the time. This is where new age personalized gifting platforms are a boon. It is now possible to add a touch of personalization to any gift item making it that much more special and meaningful for both the giver and the receiver. One can choose from functional items such as coffee mugs or calendars to more stylized gifts like Canvas Prints and Photo décor and add a favorite memory to make the gift item personal and more valuable.
