These include glaciers, frozen ground, sea ice, snow and ice. One of the main aims of the EGU Division on Cryospheric Sciences (CR) is to facilitate the exchange of information within the science community. It does so by organising series of sessions at the annual EGU General Assembly, and through the publishing of the open-access journal The Cryosphere. The division awards the Julia and Johannes Weertman medal for outstanding contributions to the science of the cryosphere.</p> <div class="headline"> <h2>Latest posts from the CR blog</h2> </div> <article class="media"> <img role="presentation" alt="" class="img-fluid img-thumbnail" src="https://www.egu.eu/media/news/blogmessages/2025/04/04/55c70733-e26e-449c-a500-88b8c0206644.jpg.120x120_q90_crop-smart_upscale.webp" srcset="https://www.egu.eu/media/news/blogmessages/2025/04/04/55c70733-e26e-449c-a500-88b8c0206644.jpg.120x120_q90_crop-smart_upscale.webp 1x, https://www.egu.eu/media/news/blogmessages/2025/04/04/55c70733-e26e-449c-a500-88b8c0206644.jpg.240x240_q90_crop-smart_upscale.webp 2x" loading="lazy"> <div class="media-body"> <a class="h4 external" href="https://blogs.egu.eu/divisions/cr/2025/04/04/feeling-unfrozen-lands-what-we-can-learn-from-research-on-ecological-grief/">Feeling (un)frozen lands: What we can learn from research on ecological grief</a> <ul class="list-inline mt-1"> <li class="list-inline-item"><i class="fab fa-fw fa-wordpress"></i> <a class="external" href="https://blogs.egu.eu/divisions/cr/">Cryospheric Sciences</a></li> <li class="list-inline-item"><i class="far fa-fw fa-calendar-plus"></i> posted 1 day ago</li> </ul> <p>Retreating glaciers, shrinking sea ice or thawing permafrost – many of you might have witnessed formerly familiar landscapes being transformed by climate change over the last years, maybe even beyond recognition. And perhaps these undeniable changes have left you feeling sad, angry or anxious about the future, fearing what lies ahead.

For those of you unfamiliar with this idea (as I once was), this is one of the final milestones a graduate student has before they are officially a “Dr.”. Upon the successful defense of a thesis, the labmates of the PhD student craft a graduation hat from a mishmash of scrap cardboard and memorabilia.
