Tracking the Footprints of a Vanishing Glaciers in the Greater Caucasus

Levan Tielidze June 13, 2025

Aerial image showing the climate change impact on small glaciers in the central Greater Caucasus, Georgia. Slopes are extensive deposits of moraines and loose rock debris, left behind by retreating glaciers. A small glacial lake (near the center-bottom of the image) fed by meltwater from the surrounding ice and snow was developed after glacier retreat [Credit: Levan Tielidze].

In this week’s blog, Levan Tielidze tells us about his recent glacier study from the Greater Caucasus. By combining geomorphology, remote sensing, and historical cartography, the team reconstructed nearly 200 years of glacier and climate change across one of the world’s most dynamic cryospheric frontiers. Glaciers’ transformation provides a high-resolution archive of post-Little Ice Age climate dy ...[Read More]

Highlighting: The Blatten landslide in Switzerland

Christophe Lambiel June 11, 2025

In the morning of May 28, 2025, the picturesque Swiss alpine village of Blatten sat quiet and serene in the Lötschen Valley. Exceptionally quiet, in fact, as the village was evacuated on May 19th after a local Natural Hazards expert spotted a worrisome change in a local mountain looming about the village, the Kleines Nesthorn: it was collapsing faster. The Kleines Nesthorn is a 3,341-meter peak w ...[Read More]

Pride Month: support your LGBTQ+ colleagues in science

Simon Clark June 10, 2025

Imagine this: you are at work, casually discussing your weekend plans with colleagues. One is planning a hike with her husband. Another jokes about meeting his girlfriend’s parents for dinner, nerves barely concealed. Then you mention a date night with your partner. The conversation halts. The atmosphere becomes taut. One of your colleagues makes a swift exit. Later that day, your boss calls you i ...[Read More]

Monitoring the Ocean’s Green Pulse: A New Global Dataset for Phytoplankton Phenology

Sandy Thomalla June 10, 2025

Phytoplankton are tiny, single-celled organisms mainly found in the ocean’s sunlit surface, where they grow through photosynthesis, forming the marine food web’s base and regulating Earth’s climate by absorbing carbon dioxide. Their seasonal growth cycles—known as “blooms”—drive marine productivity and influence everything from carbon uptake to food security. But how can we track ...[Read More]

Climate: Past, Present & Future

The rabbit and the tortoise – what does a glacial cycle need to be a glacial cycle?

Sergio Pérez-Montero June 2, 2025

The climate is not what it used to be and it will never be the same again. This is what the models say. Where does this knowledge come from? In short, we learn it from the clues that nature left on the planet since its formation. And it is precisely with these observations where our story begins. Since the beginnings of mountaineering, many visitors of the Alps and other mountain ranges have wonde ...[Read More]
