Greenland's Jakobshavn Glacier Reacts to Changing Ocean Temperatures
NASA's Oceans Melting Greenland (OMG) mission uses ships and planes to measure how ocean temperatures affect Greenland's vast icy expanses. Jakobshavn Glacier, known in Greenlandic as Sermeq Kujalle, on Greenland's central western side, has been one of the island's largest contributor's to sea level rise, losing mass at an accelerating rate.
In a new study, the OMG team found that between 2016 and 2017, Jakobshavn Glacier grew slightly and the rate of mass loss slowed down. They traced the causes of this thickening to a temporary cooling of ocean temperatures in the region.
Narrated by OMG Principal Investigator Josh Willis.

Jakobshavn glacier in Greenland is starting to grow again
A NASA study reveals that a glacier in Greenland is now flowing slower, thickening, and advancing towards the ocean instead of retreating farther inland.

YGL Greenland Expedition - Glacier Calving at the Jakobshavn Glacier (May 25, 2019)
In May, Jaime Nack co-hosted an Arctic Expedition with Active Philanthropy and the World Economic Forum for 20 Young Global Leaders to Ilulissat, Greenland. The focus of the expedition was to allow the diverse group of leaders from 16 countries to witness the climate crisis firsthand and to develop individual climate action plans.

About the Glacier:
Ilulissat Glacier Greenlandic: Sermeq Kujalleq is a large outlet glacier in West Greenland. It is located near the Greenlandic town of Ilulissat and ends at the sea in the Ilulissat Icefjord.
CHASING ICE captures largest glacier calving ever filmed - OFFICIAL VIDEO
This rare footage has gone on record as the largest glacier calving event ever captured on film, by the 2016 Guiness Book of World Records.
On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water.
Footage produced by James Balog ( and the Extreme Ice Survey (
Chasing Ice won the award for Excellence in Cinematography at the 2012 Sundance Film Festival and a 2013 Emmy Award for Outstanding Nature Programming. It has won over 40 awards at festivals worldwide, and was also nominated for an Academy Award for Best Original Song, Before My Time by J. Ralph featuring Scarlett Johansson and Joshua Bell.

The sudden breaking off of massive ice chunks from the edge of a glacier is an extraordinary sight. In our time of global warning, it is also an alarming one: a clear indication that we are heating up the planet at an alarming rate. Here are views of the Eqi Glacier in West Greenland, the most frequently calving glacier, as well as aerial views of the Jakobshavn glacier, one of the fastest shrinking glaciers and the most productive of icebergs in the world.
This massive chunk of ice covering Greenland, the biggest island on the planet, accounts for around 10 percent of the frozen freshwater on Earth. If all that were to melt, it could raise global sea levels more than 20 feet.

World's fastest glacier. Calving enormous iceberg in Greenland.
World's fastest glacier, calving enormous iceberg. Captured in a plane, by me, Ruben Wernberg Poulsen. I was only 12 years old and i filmed this with an iPad. Sorry for the unstable camera
Me and my family, wanted to see the ice on Greenland, so we bought at 30min flight that would give us a look at the ice from a new angle, I brought my iPad to take pictures.
Our pilot spotted some 'ice dust' and we wondered what it was. Then all of a sudden, this gigant iceblock breaks off. We ended up flying 60 minutes instead of 30. Our pilot had never seen anything like it. And we were all so freaked out.
It was indeed a 'one in a lifetime experience.' And it was also very lucky that we were there at that exact time.
Our pilot said I've flew past this ice in 4 years, sometimes 8 times a day, and I have never seen anything like it

Jakobshavn Glacier Retreat, Greenland | NASA
Jakobshavn Glacier, also known as Sermeq Kujalleq (in Greenlandic) and the Jakobshavn Isbræ (in Danish), is a large outlet glacier in West Greenland. It is located near the Greenlandic town of Ilulissat (Danish: Jakobshavn) and ends at the sea in the Ilulissat Icefjord. Jakobshavn Glacier drains 6.5% of the Greenland ice.

A study has found that Greenland's fastest-thinning glacier is growing again, but scientists say that it may just be temporary.
According to NASA JPL, the Jakobshavn glacier in Greenland has been thinning and retreating over the last 20 years.
But research published in Nature Geoscience has found that since 2016, the glacier's melting has slowed.
NASA reports that it also grew taller by 100 feet between 2016 and 2017.
Researchers suspected that this was due to a climate pattern known as the North Atlantic Oscillation, which cools then warm the North Atlantic Ocean every five to 20 years. In 2016, the water temperature in Disko Bay cooled, reaching temperatures that were lower than in the late 1980s.
The team used an ocean model to trace the cool water to a current that carries water around Greenland's southern tip, and northward along its west coast.
The Associated Press reports that according to study co-author and NASA climate scientist Josh Willis, the findings indicate that glacier retreats and advances are much more sensitive to ocean temperatures than previously thought.
Temperatures are still rising slowly from global warming, and with over 90 percent of heat trapped by greenhouse gases going to the oceans, melting will be worse in the long run.
RUNDOWN SHOWS:
1. Jakobshavn glacier melting
2. Jakobshavn glacier thickening, melting more slowly since 2016
3. Water temperature changes in Disko Bay
4. Depiction of North Atlantic Oscillation

Melting Greenland glacier is growing again
NASA says the world's fastest melting glacier, Jakobshavn in Greenland, has gained ice. However, it does not mean the threat of climate change is over. CBS News contributing meteorologist Jeff Berardelli joins CBSN AM to discuss the glacier and what this means for the future of rising sea levels.

Scientists Caution That Changes In Greenland's Jakobshavn Glacier Are Temporary
CNN reports that Greenland's largest glacier, Jakobshavn, is gaining ice. The increase in ice accumulation was discovered by NASA researchers. Scientists studying the critical glacier attribute the gain to localized ocean cooling..While this finding is surprising and temporarily good news for the glacier, Ala Khazendar, lead scientists on the study cautions; This is a reprieve, not a resurrection. For two decades, Jakobshavn sustained remarkably consistent thinning that scientists thought would continue, if not accelerate, leading to rising sea levels.

Study could help scientists track sea level rise
Researchers aboard the Adolf Jensen spent this summer setting up instruments along the Helheim glacier and taking ocean samples from within its fjords. The data they gleaned from the expedition could help predict future changes in sea-level, an elusive yet critical mission for climate scientists.

Watch a Drone Tour of Greenland's Glaciers
After a blazing-hot July, over 200 billion tons of Greenland's ice sheet has melted away.
VICE News traveled to Greenland last year and got to see some of the glaciers that are under threat.

Incredible GLACIER COLLAPSE & TSUNAMI WAVE Caught on Camera! | Greenland's Melting Ice
Icebergs breaking from the Ilulissat Glacier are often up to 3,000 feet in height (1 km) and thus too tall to float down the fjord and lie stuck on the bottom of its shallower areas, sometimes for years, until they are broken up by the force of the glacier and icebergs further up the fjord.
Ilulissat Icefjord drains 6.5% of the Greenland ice sheet and produces around 10% of all Greenland icebergs. Some 35 billion tonnes of icebergs calve off and pass out of the fjord every year. (
As the huge icebergs collapsed, the glacier calving event even caused tsunami waves up to 16 feet in height (5 m) breaking on the shore.

Keeping a Close Eye on Jakobshavn
Jakobshavn Glacier, one of the fastest moving glaciers in Greenland, has been the focus of IceBridge survey flights for five consecutive years. Here, images from an IceBridge mission on Apr. 4, 2013 and video footage from the 2012 Arctic campaign show this rapidly changing ice stream and how IceBridge is using its suite of airborne instruments to collect crucial data on ice movement and how much glaciers like Jakobshavn might contribute to future sea level rise.
