When I was a student, Martin told me matter-of-factly that snow is hot. I probably looked as baffled as I felt (and you are probably doing the same). Were we talking about the same thing? Continue reading to discover why snow is hot! Discovering that snow is hot So why is snow hot? Most snow under Earth’s environmental conditions has a homologous temperature Th close to 1. The homologous temperatu ...[Read More]
There has been considerable disagreement amongst researchers concerning the extent of South Georgia’s ice sheet during the Last Glacial Maximum (LGM). The sub-Antarctic islands (those below the polar front) may have been completely glaciated during previous glacials, and the last largest extent of the South Georgia ice sheet was during the LGM, about 21,000 years ago. But glaciologists don’t agree ...[Read More]
More pancakes in the future – that sounds like a very good New Year’s Eve resolution for Sunday brunches, but it could also be a development of the most tasty looking sea ice shape in the Arctic. Let’s find out more! Arctic Sea Ice The growth and melt of Arctic sea ice follows a seasonal cycle. In the springtime, under the midnight sun, the sea ice begins to melt until it reaches its m ...[Read More]
The latest climate models show that Arctic precipitation is changing more rapidly than previously projected with an earlier transition to a rainfall-dominated precipitation. This rapid change in precipitation will have huge implications for the Arctic ecosystem as well as those who live within the region. Arctic precipitation change, why is it so important? The rapid change in Arctic climate, from ...[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]
Every two years, the Cryospheric Sciences division of the European Geophysical Union (EGU) elects a new representative for its early-career scientists. Starting in April 2021, Tun Jan (TJ) Young will take over the role from Jenny Turton, who is the outgoing representative. TJ shares a bit about himself and how his previous leadership experience aligns with the goals of EGU’s early career scientist ...[Read More]
Glaciers are mostly made of water. Sometimes, perhaps more than we’d like, some of that water makes a break for it by melting, the inconstant molecule… It might pootle around on the surface of the glacier a bit and get a lot of remote sensers very excited, but it’s what it does once it gets to the base of the glacier that really matters for the behaviour and flow of the ice. So, in 2000 word ...[Read More]
Albedo or albedon’t? One possible solution to global warming is to turn everything white to increase the planet’s albedo, i.e. how reflective it is (see, for example, this website). A higher albedo would be one way to reduce global warming, by reducing the amount of incoming shortwave solar radiation absorbed by the planet’s surface, which is then re-emitted as longwave radiation that ...[Read More]
With the West Antarctic Ice Sheet currently losing ice at a fast pace, leading to sea-level rise, it is very important to better understand the processes by which this ice melting occurs. In this context, Thwaites Glacier is a very good case study of an accelerating glacier, which contributes substantially to sea-level rise, and for which a huge scientific collaboration effort has recently been se ...[Read More]
