When you think of California, with its sun-soaked beaches and Hollywood glamour, glaciers may not be the first thing that spring to mind – even for ice nerds like us. However, Yosemite National Park in California’s Sierra Nevada is famous for its dramatic landscape, which was created by glacial action. With our latest image of the week we show you some of the features that were left behind b ...[Read More]

The blue curves show the δOxygen-18 values for NorthGRIP in Greenland (top) and WAIS in Antarctica (bottom) for the last 20,000 years. The black dots are 1,000 years values, and the far left hand side of the curves are present day values.

New Year’s Eve is just around the corner and the last “image of the week” of 2016 will get you in the mood for a party. If your celebration needs a soundtrack with a suitably geeky touch then look no further. Here is the music for climate enthusiasts: The sound of the past 60,000 years of climate. Scientist Aslak Grinsted (Centre for Ice and Climate, University of Copenhagen, Denmark) has transfor ...[Read More]

If glaciers could speak, you might imagine them saying – “HELP!” The planet continues to warm and this means glaciers continue to shrink. Our new image of the week shows a glacier that appears to be making this point in a rather dramatic and gruesome way – it appears to be bleeding! If you went to the snout of Taylor Glacier in Antarctica’s Dry Valley region (see map ...[Read More]

At first glance our image of the week may look like an ordinary stoney beach…but if you look more closely you will see that this beach is not, in fact, covered in stones or pebbles but balls of ice! We have written posts about many different weird and wonderful ice formations and phenomena (e.g. hair ice or ice tsunamis) here at the EGU Cryosphere blog and here is another one to add to the l ...[Read More]

While the first week of COP22 – the climate talks in Marrakech – is coming to an end, the recent election of Donald Trump as the next President of the United States casts doubt over the fate of the Paris Agreement and more generally the global fight against climate change. In this new political context, we must not forget about the scientific evidence of climate change! Our figure of the week, tod ...[Read More]

When working in the middle of an ice sheet, you rarely get to experience the amazing wildlife of the polar regions. So what are we doing hundreds of kilometres from the coast with an animal tracker device? We are listening to the snow of course! It is not crazy; It is what Image of the Week today is all about! Going Wireless In June 2016, Liz Bagshaw and I travelled to the EGRIP (East Greenland Ic ...[Read More]

Image of The Week – Prize Polar Pictures!
Permafrost thawing and its impacts on reindeer breeding.. This figure was created by Noémie Ross - a young graphic designer and illustrator from Montréal, Canada., as part of the ‘A Frozen-Ground Cartoon’ project. It won 1st place at the 2016 Fall APECS International Polar week figure competition. Click here to enlarge the image.

Last week was the Fall APECS International Polar Week, designed to promote and celebrate the great collaborative science that goes on around the world to further our understanding of the polar regions. Part of this celebration was a figure competition, to find the most “eye-catching, informative and inspiring” figures that illustrate aspects of polar science. What better, we thought, t ...[Read More]

“Tsunami“ is a word that became world famous after the so-called Christmas tsunami in 2004, when enormous waves hit the shores around the Indian Ocean with disastrous consequences for countries such as Sri Lanka, Thailand, Somalia and many others. But did you know that tsunamis can be icy? An ice tsunami is one of the many names associated with ice shoves (or ivu, shore ice override, i ...[Read More]

The 30th August 2016 marks 100 years since the successful rescue of all (human) member of Shackleton’s Endurance crew from their temporary camp on Elephant Island (see map). Nearly a year prior to their rescue they were forced to abandon their ship – The Endurance – after it became stuck in thick drifting sea ice, known as pack ice, trying to navigate the Weddell Sea. It was the last major e ...[Read More]
