Last week, the EGU Cryosphere Blog (“Cryoblog” for the regulars) team was contacted by a reader who stumbled upon very curious ice formations while taking a morning walk in rural Berkshire, England. This was right after a few nights with below-freezing temperatures and snowfall. He asked us whether we could explain to him what these ice mushrooms were and how they formed. Very curious and always k ...[Read More]
How do the ups and downs of the solid Earth influence the future of the West Antarctic ice sheet?
When the Antarctic ice sheet loses mass, the pressure it exerts on the underlying solid Earth decreases. As the ice sheet becomes less heavy, the Earth’s surface is not pressed down as much as before and therefore slowly rises up. In some regions, this rebound process is much faster than previously thought and could stabilise areas of unstable ice retreat. How come? Keep reading to figure it out… ...[Read More]
Image of the Week – Desert Varnish, Antarctica Style
If you had to describe Antarctica with one colour, red is probably the last one you would pick. However, some parts of the so-called white continent can be surprising in their colours. Today’s Image of the Week shows us that some parts of Antarctica — Beacon Valley in this case – can be strikingly similar to landscapes in hot deserts…. … speaking of deserts, did you know that: Antarcti ...[Read More]
Image of the Week – The solid Earth: softer than you might think!
Global sea level is rising and will continue to do so over the next century, as has once again been shown in the recent IPCC special report on 1.5°C. But did you know that, in some places of our planet, local sea level is actually falling, and this due to rising of the continent itself?! Where is this happening? In places where huge ice sheets used to cover the land surface during the last ...[Read More]
Image of the Week – Will Santa have to move because of Climate Change?
Because of global warming and polar amplification, temperature rises twice as fast at the North Pole than anywhere else on the planet. Could that be a problem for our beloved Santa Claus, who, according to the legend, lives there? It appears that Santa could very well have to move to one of its second residences before the end of this century. But even if he moves to another place, the smooth runn ...[Read More]
