The Guinness Book of Sedimentology: your guide to the world’s largest EVER sedimentary landforms

There is something about really BIG things that always grabs people’s attention – look at dinosaurs for example. The geological record is littered with the extreme and today we will explore the biggest, the tallest, the deepest and steepest sedimentary structures and landforms ever to grace our planet. Depositional environments ranging from fluvio-lacustrine and aeolian, …[Read More]

The spectral shadow of Samalas: When climate models conjure the Earth’s forgotten fury

Asmae Ourkiya October 24, 2025

This Halloween, we turn our gaze from fictional haunts to the chilling, rigorous world of paleoclimatology. The paper by Hartmann et al. (2025), published on Climate of the Past, focuses on the implementation of external forcings in a regional climate model around the 1257 CE Samalas volcanic eruption. This paper can be quite the unsettling …[Read More]

Climate: Past, Present & Future

Writing Climate: a blog at the crossroads of Science, Art and Travel

Valeria Mascolo October 24, 2025

It took me many travels, experiences, and an entire PhD on climate-related topics to realize that all these dots could be connected. How I Perceive Our Warming World is a blog at the intersection of my life passions: travel, art, and climate. It is not about travel, nor about art, nor about climate alone: it …[Read More]

A photo of Dr. Isabel Ashman who's work has been featured in this blog

In this blog post, I have interviewed Dr. Isabel Ashman, who is part of the GeoSafe consortium at the University of Liverpool, looking into safe and long-term containment of radioactive waste in geological formations. Dr. Ashman, along with other project partners at the University of Liverpool, aim to better understand how small to large-scale (sub-mm …[Read More]

Bored by the Lower Mantle? Think Again!

Poulami Roy and edited by Pauline Gayrin October 22, 2025

Is the lower mantle boring? For a long time, the lower mantle was thought to be relatively featureless and uniform compared to the more dynamic upper mantle. But recent seismic observations are challenging that idea, especially when we look near the base of the mantle. Recent studies from Maureen Long’s group (Creasy et al. 2017, …[Read More]

GeoPolicy: The first case of rights of Nature in Europe: The Mar Menor Lagoon

Damla Posta October 17, 2025

The rights of Nature: A new paradigm Does Nature have inalienable rights just as humans do? This is what the rights of Nature paradigm stands for, marking a radical departure from the assumption that Nature is property under the law. The idea of rights for Nature stems from legal philosophy and political science. Partially, it …[Read More]

Faults vs. Fractures — How to Tell Them Apart ?

Nkodia Hardy October 16, 2025

$A futuristic Black geologist wearing AR glasses stands in a glowing cave surrounded by four holographic screens labeled Geological Aspect, Geometry, Topology, and Kinematics & Mechanism, each displaying geological diagrams and fracture models, symbolizing modern geoscience visualization.$

Faults and fractures can sometimes be confusing, especially for students taking their first geology courses. When they go hiking in the mountains and see a crack in the rock, they often wonder — is this a fracture or a fault? Even scientists sometimes mix the two terms, so it’s good to understand the difference. Since …[Read More]
