Do you know about OGGM-Edu? An open-source educational platform about glaciers and glacier modelling

Are you teaching about glaciers and looking for fun educational activities for your students? Are you planning a workshop about glacier modelling and want to make it interactive, with a low entry level? Are you interested in learning about glaciers and glacier modelling, and looking for a simple way to get started? On top of that, do you want to do all of the above without installing anything on y ...[Read More]

Did you know that glacier mass loss affects water resources?

The picture above shows a typical Kyrgyz summer yurt camp, located in the valley of Altyn-Arashan, Kyrgyzstan. The stream you see flowing through comes from the glacier-fed lake of Ala-Kul, the gorgeous turquoise water featured below. The families who live there during summer have done so for generations, and travel up with their herds of horses and cows. The stream provides the water they need fo ...[Read More]

Rain or snow? Answering the question with citizen scientists

Rain or snow? Answering the question with citizen scientists

As a New Englander interested in weather, I was used to a fairly intuitive air temperature split between rain and snow. Once air temperature got slightly above freezing, I’d commonly see rainfall with snowfall more frequent below freezing. Then something happened when I moved to the Intermountain West of the United States. Instead of seeing rain when it was slightly above freezing, I’d see snow at ...[Read More]

Did you know there’s a place to Find, Discover, & Download Arctic Data? Meet The Arctic Data Center!

Getting data from the Arctic is often difficult and expensive – instead, stand on the shoulders of giants and investigate over 6000 datasets preserved for future download and reuse in the Arctic Data Center! Read on for more information about the Arctic Data Center and the data contained therein. The Arctic Data Center is the primary data repository for the Arctic section of the US National ...[Read More]

Did you know … that liquid water can be held within a glacier?

Did you know … that liquid water can be held within a glacier?

Hidden below the surface of some glaciers, liquid water can be found within what is called the firn layer – the upper layer of a glacier where snow compacts into glacier ice. Liquid water may persist there for up to many years, forming what scientists call “firn aquifers.” While observations of seasonal firn aquifers have existed since the mid to late 1900s in several mountain glaciers, recent stu ...[Read More]

Cryo-massy Films

There are countless Christmas films, and almost all of them feature some form of snow, ice or cold weather. There are the classics such as Home Alone, Elf and Miracle on 34th Street, and there are the newer, shall we say ‘Netflix’ style, which feature Princes, Knights and Vanessa Hudgens. There’s just no way to watch them all over the festive period, so let us recommend you our top 5 Christmas fil ...[Read More]

Hysteresis For Dummies – Why history matters

Hysteresis For Dummies – Why history matters

Perhaps you have stumbled upon the word ‘hysteresis’ before, for example in connection with the stability behavior of our Earth’s large ice sheets and their long-term effect on global sea-level rise, or the long-term stability of the Atlantic Meridional Overturning Circulation, or even in another context outside earth/climate science. Or you might have come across this term during your studies, bu ...[Read More]

How small changes can make a big difference: tipping points in Antarctica

How small changes can make a big difference: tipping points in Antarctica

As Antarctica’s mass loss increases, the threat of crossing tipping points both in the ice sheet and the surrounding Southern Ocean is increasing. But what actually is a tipping point? Have tipping points already been crossed in the past? And what might the future hold? What do we mean by a “tipping point”? Scientifically speaking, a tipping point is generally understood to be a threshold that, on ...[Read More]

Running a live stream of proglacial processes

In Switzerland, nothing is really remote, but some places are more so than others. Dense infrastructure networks typically provide convenient access to research sites in the Alps where it is difficult to feel far away from home. However, this is not always the case… For us, our home for the summer is a bit different. We work at 2400 m above sea level in Southern Switzerland, in a narrow vall ...[Read More]

The physical and social changes facing the mountainous populations of the Karakoram Range

The physical and social changes facing the mountainous populations of the Karakoram Range

As a child, Shakir remembers long extreme winters with heavy snowfall and dry blistering winds, where it was hard to play outside. He grew up in a village named Gulmit, located at an elevation of 2500 m, surrounded by the high snow caped mountains in the Karakoram Range in northern Pakistan. That was 30 years ago, when climate change was still not a cause of concern for the local people. Today, in ...[Read More]
