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, Wolf et al. 2019, Reiss et al. 2019, Wolf & Long, 2023) and othe ...[Read More]
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 is a product of the concept deep ecology, developed by the Norwegian ph ...[Read More]
In this blog post Dr Levan Tielidze from Monash University and Securing Antarctica’s Environmental Future shares insights from a new glacier assessment of Heard Island. Although rarely visited and largely unknown, Heard Island plays an outsized role in understanding how the Southern Ocean cryosphere is responding to global warming. The island is one of the few sub-Antarctic locations with active g ...[Read More]
Between October 5 – 10, 2025, the XIIth Scientific Assembly of the International Association of Hydrological Sciences (IAHS) took place in Roorkee, India. Overall, more than 600 hydrologists assembled on the campus of the Indian Institute of Technology (IIT) to share their latest progress, discuss with their colleagues, nurture connections, and celebrate hydrology as a discipline. Here’s a ...[Read More]
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 faults and fractures are important in many fields such as tunnel engineering, hy ...[Read More]
In this new blog, Dr. Kai Li (GFZ Potsdam) talk about his PhD work, where he used accordion numerical models to explore the tectonic history of the South China Sea. His PhD research focuses on the impact of orogenic inheritance on rifts and rifted margins, employing advanced geodynamic modeling techniques. Have you ever tried to fit the west coast of Africa and the east coast of South America toge ...[Read More]
