A call to action - World Glacier Day
As you can see - you don't see anything.
Here I have a photo of the Kaldidalur track, a road in the Icelandic highlands, between the Langjökull glacier and Ok. To the right of this piste you can see the foothills of Langjökull glacier. On the left side, behind the dark, steep mountain, lies the Ok, relatively inconspicuous.
With a size of around 900 km², Langjökull is the second largest glacier in Iceland . The Langjökull ice sheet lies on the Western Rift Zone, and at least two volcanic systems are partially beneath this glacier.
The Ok (then Okjökull) used to be a glacier. Now the Ok is no longer a glacier.
Around 1900, the area of this glacier covered an area of almost 40 km². But by the 1970s there was only around 3 m² left. And the ice sheet continued to melt.
In 2014, Okjökull was officially declared "dead".
The ice sheet that used to be on the 1,177 meter high mountain no longer moves because the ice layer has become too thin and light. Nothing moves anymore. Geologically speaking, Okjökull is no longer a glacier, but rather just a shield volcano with a snow cap. The glacier has disappeared.
Ok is the first Icelandic glacier to lose its status as a glacier.
In the next 200 years all our glaciers are expected to follow the same path.
This monument is to acknowledge that we know
what is happening and what needs to be done.
Only you will know if we did it.
The numbers show - so far we haven't done it.
It is too late to save the Ok, but other glaciers could still be saved.
In recent decades, glacier retreat has accelerated worldwide, to varying degrees. The retreat of glaciers in Iceland is particularly serious: in the last 100 years, Iceland's glacier area has shrunk by 20%. Almost half of the decline took place in the last 20 years. If glacier retreat continues at this rate, most Icelandic glaciers will be gone before the end of the 21st century.
As the glaciers retreat, the glacial lakes expand and new lakes are created. Rivers change their course, the flow of the watercourses changes. Land uplift near glaciers is increasing. Mountain tracks become unstable and the risk of landslides and mudslides increases. The melting of glaciers also has an impact on the infrastructure, the supply of fresh water and energy to the population (see electricity generation from hydropower).
Now it's time to act.
The future of Iceland's glaciers depends heavily on the development of the climate and sea temperatures around Iceland. By reducing greenhouse emissions worldwide, it would still be possible to limit global warming and thereby reduce the loss of glaciers worldwide.
World Glacier Day on March 21st
In 2022, the United Nations designated March 21st as "World Glacier Day", the first time this day took place today on March 21st, 2025 .
Actions around this day are intended to draw attention to the effects of glacier retreat on people and ecosystems, and strategies are also to be developed to limit the effects of climate change and, if possible, at least improve local adaptation to the changing conditions.
For me it was an experience when I saw a glacier in Iceland for the first time in 2004. And today, when we have visitors, I love taking our guests to Sólheimajökull, a glacier tongue of Mýrdalskökull, to show them where this "island of fire and ice" gets its name.
If future generations are to continue to experience glaciers on Iceland in 100 years, we all have to act - I am personally convinced of that. Otherwise the other Icelandic glaciers will end up just like Ok, which is no longer a glacier.
