Survivors! Resilience and adaptations of freshwater ostracodes in ancient Lakes Petén Itzá (northern Guatemala) and Chalco (central Mexico) to climate and environmental changes over the last 80,000 years

Liseth Pérez and Claudia Chávez September 28, 2023

The North American Tropics hosts lakes of diverse origins and limnological characteristics, which are located along a broad altitudinal gradient, from 0 to 5675 masl. The region possesses several ancient lakes that have accumulated sediments continuously, in some cases for >400,000 years. Study of those lake deposits has enabled scientists to infer past climate …[Read More]

Nonlinear Processes in Earth System Dynamics

Gabriele Messori September 27, 2023

Earth System Dynamics (ESD) is an open-access EGU journal focussing on an interdisciplinary view of the functioning of the Earth system and global change. Due its broad focus, ESD receives submissions of relevance to several different EGU divisions. Here, I would like to highlight five thought-provoking ESD papers that cover topics spanning environmental governance, extreme …[Read More]

Dual inward dipping subduction: A Christmas Cracker Model

edited by Zhibin Lei September 27, 2023

A recent research finds that dual inward dipping subduction framework, after considering thermal dependent deformation mechanisms, can pull apart the middle overriding plate (Lei and Davies, 2023), just like pulling Christmas crackers from both ends! Dual inward dipping subduction (DIDS) occurs when the overriding plate is decoupled with two subducting slabs dipping towards each other. …[Read More]

Maria Katherina Dal Barco September 25, 2023

High tide captured during the morning of November 6th, 2023 in Piazza San Marco, Venice (Italy). The MOSE system of mobile gates, designed to defend the Venice lagoon from tides up to 3 metres high, is not activated for tide levels below 110 cm. However, when the tide reaches 83 cm, the lowest point of …[Read More]

Small step for reindeer – large leap for humankind?

Torben Windirsch September 22, 2023

Photo of a reindeer looking for food on the snow.

Since several decades, there’s a lot of discussion in the permafrost ecosystem community on “rewilding” and “return to a natural state” in order to protect ecosystems and to reduce the impacts of climate change. Reindeer and other herbivores influence the insulation regime of the ground and could thereby preserve the frozen state of permafrost ground. …[Read More]
