glaciers

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

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]

Image of the Week – Karthaus Summer School 2018

Nearly every year since the late 90s, during the summer, the picturesque Karthaus has hosted 10-day glaciology course. This school is a platform for glaciologists to explore, learn and expand their knowledge base. This helps researchers become multi-faceted: to view glaciology from the perspective of those specializing in other backgrounds such as hydrology, geomorphology, oceanography, etc. which ...[Read More]

Image of the Week – Inspiring Girls!

What, you may ask, are this group of 22 women doing standing around a fire-pit and what does this have to do with the EGU Cryosphere blog? This group of scientists, artists, teachers, and coaches gathered 2 weeks ago in Switzerland to learn how to become instructors on an Inspiring Girls Expedition. But what, you may ask again, is an Inspiring Girls Expedition? Well read on to find out more… ...[Read More]

Image of the Week – Microbes have a crush on glacier erosion

Glacier erosion happens at the interface between ice and the ground beneath. Rocks are ground down to dust and landscapes shaped by the flowing ice. While these might be hotspots for erosion, the dark and nutrient-poor sites are unlikely environments for biological activity. However, experiments suggest there may be novel sources of energy powering subglacial microbial life… Where there is water, ...[Read More]
