Running a live stream of proglacial processes

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]

Climate Change & Cryosphere – Glacier retreat poses new challenges in the Central Andes

Climate Change & Cryosphere – Glacier retreat poses new challenges in the Central Andes

When you hear of Chilean glaciers, you probably think about the large glaciers of Patagonia. However, glaciers can be found further north in Chile as well (see this previous post). While the melting of the Patagonian glaciers mainly affects the global human population by contributing to sea level rise, the retreat of glaciers in central Chile affects the local human population directly in terms of ...[Read More]

Did you know… the Andes are so cryo-diverse?

Extending for almost 8,000 km along the west of South America, the Andes are the longest continental mountain range in the world. They portray an impressive richness and diversity of cryospheric features, including: the most substantial extension of tropical glaciers on Earth, one of the highest densities of rock glaciers, the largest glacierized area in the Southern Hemisphere outside Antarctica, ...[Read More]

Did you know… the surface of melting glaciers is one of the most radioactive places on Earth?

Did you know… the surface of melting glaciers is one of the most radioactive places on Earth?

Recent studies show that glaciers are significantly affected by pollution, and in general by human activities, but few people would imagine that their surface contains traces of nuclear contamination and radioactivity. It has been recently claimed that high amounts of radioactivity have accumulated on glaciers, only beaten by the radioactivity levels of sites where nuclear incidents and tests have ...[Read More]

Water plumes are tickling the Greenland Ice Sheet

Water plumes are tickling the Greenland Ice Sheet

7 meters of sea-level rise – what you would get if the whole Greenland Ice Sheet melted. But the tricky question is: how much of this ice will be melted in the next decades, and how fast will it occur? This piece of information is critical in order to plan for present and future populations living in coastline areas, all around the world. How much and how fast can the Greenland Ice Sheet melt ? In ...[Read More]

Climate Change & Cryosphere – The fate of Georgian Glaciers

Last week, we learned about the dramatic fate of the Hochjochferner, which has strongly retreated in the past years due to climate change. It represented just one example amongst many alpine glaciers, which are following a similar path. But the Alps are not the only mountain range in which glaciers are retreating. Another example closeby is the Caucasus region. Its glaciers are also shrinking at a ...[Read More]

Ice-hot news: The IPCC Special Report on the Oceans and the Cryosphere under Climate Change

Ice-hot news: The IPCC Special Report on the Oceans and the Cryosphere under Climate Change

You have probably heard the name “Intergovernmental Panel on Climate Change (IPCC)” mentioned frequently over the last few years. The IPCC is the United Nations body for assessing science related to climate change and it publishes global assessment reports on this topic every 5 to 10 years. Due to the current urgency of the global climate crisis and the need for more information by decision makers ...[Read More]

Surviving in cold environments: from microbes under glaciers to queer scientists in the current social context

Surviving in cold environments: from microbes under glaciers to queer scientists in the current social context

On the 5th of July we will celebrate the International Day of LGBTQ+ (lesbian, gay, bisexual, transsexual, queer, and people that do not identify themselves as cis and/or straight) People in Science, Technology, Engineering, and Maths (STEM). Many people will ask: “Why is this day important?” Being a queer scientist in particular, and a queer person in general, can sometimes reminds us of how livi ...[Read More]

Image of the Week – Ice-Spy: the launch of ICESat-2

On September 15th, 2018, at 18:02 local time, NASA launched its newest satellite – the second generation Ice, Cloud and land Elevation Satellite (ICESat-2). ICESat-2 only contains one instrument – a space laser that fires 10,000 pulses per second to Earth to measure elevation. Its primary purpose is for monitoring the ever changing cryosphere, so naturally there are plenty of ice enthusiasts ...[Read More]

Ice-hot news: The cryosphere and the 1.5°C target

Every year again, the Conference of Parties takes place, an event where politicians and activists from all over the world meet for two weeks to discuss further actions concerning climate change. In the context the COP24, which started this Monday in Katowice (Poland), let’s revisit an important decision made three years ago, during the COP21 in Paris, and its consequences for the state of the cryo ...[Read More]
