As scientists, we often encounter errors in our own work and in the work of others. As modelers, we call these errors “bugs”. Of course, they are not actual insects, but they definitely keep us awake from time to time. Even though everyone is aware of their existence, we rarely discuss them in a scientific context. In today’s post, I bring to you the work and journey of a snow scientist, Dr. Cécil ...[Read More]

I am a hobby ornithologist and love watching birds. It is fun and relaxing to search the trees or fields for feathered friends. One has to be aware of their surroundings, which can make birding even meditative. Here, I will tell you more about Arctic breeding birds, their population declines and I present to you three birds of the many I saw on my very first trips to the Arctic. Arctic breeding bi ...[Read More]

It’s no secret that the Arctic is warming faster than the rest of the planet, but why? Polar Amplification (often called Arctic Amplification) is the mechanism at play. In this week’s blog, we find out about its origins and why it happens. Early Discoveries In 1969, Russian scientist Mikhail Budyko and US scientist William Sellers discovered independently that the increase in greenhouse gases comb ...[Read More]

It is a pleasure for the EGU Cryoblog team to present a new post category: Cryo-institutes around the world! There are many institutes working on cryosphere-related research spread around the world. The aim of this new category is to highlight the cool research that is carried out at these institutes, showing off our multi-faceted cryo-related science. In this opening post, Ashley Morris will pres ...[Read More]

The “Cliffs Notes” on Ice-Cliff Failure

The retreat of large glaciers that drain the Greenland and Antarctic ice sheets could expose immense ice-cliffs at newly-bared calving faces, which are the exposed ends of glaciers where, in these cases, glacier ice meets the ocean. Past a certain height, these ice cliffs will become susceptible to collapsing from high stresses, a process known as structural ice-cliff failure. If a taller ice clif ...[Read More]

What’s on at POLAR18?

Emma C. Smith June 13, 2018

Next Tuesday (19th June) the POLAR18 Open Science Conference kicks off in Davos, Switzerland. We have put together a quick guide about events that might be of interest to you during the week! Conferences are about the science, of course, but the social side is just as important 🙂 What is POLAR18? The eagle-eyed among you will have spotted that the POLAR18 conference is, in fact, a collection of di ...[Read More]
