MELTING GIANTS

The once mighty glaciers of the Alps are melting away. According to scientists, almost all of them could be gone by the end of this century due to rising temperatures. “Melting Giants” is capturing the beauty of our glaciers and their decline.

About Melting Giants

Since my childhood, I am fascinated by these ice giants. During my hikes in the Alps, I have witnessed their decline at first hand. When I learned that most glaciers could be gone by the end of the century, I knew that I wanted to raise awareness. With this project, I want to document our melting ice giants in the Alps and capture their beauty. On the one hand, to show future generations what we have lost; on the other hand, and even more importantly, to showcase the issue to a broad audience, thereby hopefully accelerating climate protection. We have only one planet and need to start to take responsibility for our actions. 

“The glaciers are the fever thermometers of the earth”. Our earth has already warmed over one degree Celsius, and currently we are heading towards two degrees. It is scientifically proven that we humans are responsible for the current climate change. Due to the rising temperatures, our glaciers are melting away. The huge amounts of ice and snow that have formed and shaped the alpine landscape of the Alps are disappearing faster and faster. What is happening to the glaciers in the alps is also happening on Greenland, in the Himalayas, in the Andes, in the Arctic and in the Antarctic – in some cases to an even greater extent. Unfortunately, areas such as the Alps and the polar region are experiencing rapid warming. For this project, our alpine glaciers serve as a symbol for the worldwide conditions of glaciers and ice sheets. 

When I started working on this project in 2022, studies suggested that most of Austria's glaciers could disappear by the end of the century. At the time, I was 27 and used to joke that I would photograph glaciers until I died. However, three years later in 2025, the latest studies were forecasting that Austria could be ice-free within 40 to 50 years due to the rising temperatures. It now seems that, at the age of 30, I could potentially outlive the ice giants that were once called 'the eternal ice'.

Is it too late?

Can we still save the melting giants, or will all of our glaciers disappear? Luckily, it is not too late. There is still hope, that we can save at least some. However, a majority will be lost. There are regional differences, and it all depends on if we can limit global warming. We are currently heading towards 2.7 °C of warming by 2100. That would mean, that less than a quarter of global glacier mass will be left. Austria, for example, would be essentially ice free. However, if we can limit temperature increase to 1.5 °C (the goal of the Paris Agreement), about half of the global glacier mass could remain. Every tenth of a degree of global warming matters. BUT we have to act now.

You can find a good visualization of the difference between 2.7 °C and 1.5 °C for several glaciers in the Alps created by scientists from the University of Innsbruck here: https://goodbye-glaciers.info

This metal plate (lower left corner) was put at the edge of the ice in September 2016. The picture was take in September 2023, 7 years later. The edge of the ice is now at least 25 meter away and 5 to 6 meter lower.

Some numbers and facts about glaciers and their decline:

Giants

  • there are approximately 5000 glaciers in the Alps

  • the longest glacier in the Alps, the Aletsch glacier, is around 22 kilometres long

  • at the Konkordiaplatz in Switzerland, the ice is roughly 900 metres thick

  • there are around 900 glaciers in Austria with an average thickness of 38 metres and a volume of 17,7 cubic kilometres

Melting

  • if global warming stays at 1,5 degrees, about half of the glaciers will disappear until 2100

  • if global temperatures rise up to 2,7 degrees, nearly all glaciers in many regions, like the Alps, could vanish

  • for example, the Hintereisferner in Austria lost 5% of its volume in only one year

  • in Switzerland, glaciers have lost half of their ice mass between 1931 and 2016 and since 2016 have lost additional 12%

Why we should care

Glaciers are not only incredible to look at. They are important for several reasons. The ice acts as a water reservoir for nature and humans alike. They continuously supply the valleys with water in summer. Once they have disappeared, this water is missing for nature and humans. This is especially relevant in Asia, where the glaciers in the Himalayas provided water for millions of people. It is estimated that at least 700 million people rely directly on glacier and snow melt for freshwater.

Moreover, the melting of the ice affects the rise of the sea level. Rising sea levels threaten millions of people all over the world. The glaciers in the Alps are so “small” that in total the sea level would “only” rise by 10 to 20 centimetres. However, glaciers and ice sheets are melting on a global scale. If all the ice on Greenland melts, water levels would rise by about 7.5 meters. Alone the ice in Antarctica can lead to a rise of about 60 meters. Today, roughly 200 million people live below 5 meter above sea level. Depending on the global temperature increase, sea levels will rise by 60 centimetres to several metres by 2100, directly threatening these people. A useful tool to see the impact of rising sea levels is the interactive map by Climate Central. Feel free to play around: Climate Central Sea Level Rise Map.

In addition, glaciers influence the stability of the mountains. With their disappearance, mountains become unstable and huge landslides can happen, creating a danger for villages and people. Mountaineers face more unpredictable risks, as seen in 2022 at the Marmolada glacier in Italy, where a part of the glacier collapsed, killing seven people. Other dangers include glacier lakes that break their banks and flood the valley below. Such glacier lake outbursts are especially a problem in Asia, but could also endanger local communities in the Alps.

Lastly, melting glaciers are just one consequence of climate change. Rising temperatures lead to more extreme weather events such as heavy rainfall, droughts or heat waves, affecting people all over the world. The indirect consequences of climate change that impact us humans and our environment include an increase in hunger and water crises, threat to livelihoods from floods and forest fires. Health risks due to increase in frequency and intensity of heat extremes. They also include economic consequences for remedying climate-related damage or further spread of pests and pathogens.

As you can see, climate change affects all of us. There are so many reasons why we should care and why we need to act now.

Watching our glaciers vanish

As part of the project and to visualise the retreat of glaciers, I return to certain ice giants every year or two to take photos from the same position. You can see all the comparisons shots that I have taken so far here:

What we can do

Climate change is a systemic and global issue. Addressing it requires systemic change, meaning broad, fundamental alterations in how society is structured and operates rather than just isolated solutions. We need transformations across different sectors such as transportation, food supply, energy generation or housing. Thus, a major thing we can do is VOTE and demand from our governments to act. By voting for parties that aim at fighting climate change, you can do a lot for our glaciers and nature in general. Although individual choices matter, it is collective action that can stop climate change. We need to build broad coalitions for change – across communities, sectors and generations. It is all about shared responsibility and collective action. Citizens, communities, businesses, and governments all have roles to play, but these roles differ according to access to resources and decision-making power.

Handprint vs. footprint: You probably have heard about the so-called “carbon footprint”. This concept, developed by the oil corporation BP at the beginning of the 1990s, is intended to illustrate the greenhouse gas emissions caused by a person's diet, housing, transportation and so on. The higher the emissions, the larger the symbolic footprint. However, the focus on your individual carbon footprint can be demotivating. Even with great individual efforts, a considerable amount of emissions remains, resulting from the general infrastructure, the widely accepted lifestyle or a lack of alternative actions. This could lead to the impression that the fight against climate change has already been lost. And this is where the so-called “carbon handprint” comes into play. It is used to calculate and symbolise what one has already achieved, showing what progress has been made rather than what still needs to be done. According to this concept, everyone has the opportunity to increase their “carbon handprint” — potentially to infinity. The handprint grows with changes in one's own behaviour, but it can also include indirect effects achieved with other people. It can be applied to all areas, including private behaviour, political commitment, and professional actions in decision-making positions within companies, for example. However, we must not completely ignore the carbon footprint. In general, emissions must be reduced. With little tweaks in your daily life, you start making a difference.

You do not have to go all vegan, never fly or use a car again and live in a cave without electricity. I mean, if you want to, do it, nature would be happy. But for many people, that is just not possible. The most important thing is, that you do the best you can and start to implement changes in your life. How about one or two days per week when you don’t eat meat or even eat completely vegan? Maybe use public transportation more often instead of your car? If you drive on the highway, try to avoid driving really fast (maybe try to drive not more than 120 km/h). Or try to buy less and reuse and repair things. There are many ways to reduce your impact. Tell others how they could also reduce theirs and make people aware of the consequences of climate change. You can find many ways on how to reduce your carbon footprint on the internet and decide for yourself, which options are the best ones for you. If you decide to donate money to offset your carbon emissions, look for the “Gold Standard” certification. I can recommend companies like atmosfair (https://www.atmosfair.de/de/). And remember, you do not need to be perfect, just do the best you can.

Last but not least: Use your voice! Spread the word and inform others. :)
