The number of snow cover days in the Alps could halve by the end of the century due to higher temperatures if greenhouse gas emissions remain high, according to new research published today in the European Geosciences Union journal Hydrology and Earth Sciences.
The European Geosciences Union and our publishing partner Copernicus are announcing sweeping new changes, that will give our authors the ability to make vital alterations to their names in previously published scientific literature. This will allow researchers to change their name for several reasons, from a need by transgender authors to change their first name to affirm their gender, to a change in marital status, to cultural name changes, or any other reason.
Researchers use computer simulations to show that extreme weather phenomena can be controlled and modified by making small adjustments to variables in the weather system. The study’s findings promise multiple future applications where weather events can be better controlled, including the effects of climate change.
Jakub Stepanovic, a mixed-media artist who focuses on mapping and the environment and Kelly Stanford, a digital artist and science communicator, have been selected for a residency at the next European Geosciences Union (EGU) General Assembly 23–27 May 2022. Our previous Artist in Residence, Elena Popova, will unfortunately no longer be able to join us in 2022.
The Union is gravely concerned by the recent invasion of Ukraine, and hopes for a swift and peaceful resolution, achieved through co-operation and negotiation, rather than aggression.
Permafrost thaw-driven landslides in the western Arctic are increasing organic carbon delivered to headwaters of drainage networks in the western Canadian Arctic by orders of magnitude. Through a series of laboratory experiments, we show that less than 10% of this organic carbon is likely to be mineralized to greenhouse gases during transport in these networks. Rather most of the organic carbon is likely destined for burial and sequestration for centuries to millennia.
The stratosphere is emerging as one of the keys to improve tropospheric weather and climate predictions. This study provides evidence of the role the stratospheric ozone layer plays in improving weather predictions at different timescales. Using a new ozone modelling approach suitable for high-resolution global models that provide operational forecasts from days to seasons, we find significant improvements in stratospheric meteorological fields and stratosphere–troposphere coupling.
By comparing two models for the transport of sediment, we find that they share a similar steady-state solution that adequately predicts the shape of most depositional systems made of a fan and an alluvial plain. The length of the fan is controlled by the size of the mountain drainage area feeding the sedimentary system and its slope by the incoming sedimentary flux. We show that the models differ in their transient behaviour to external forcing and are characterized by different response times.
During this year’s EGU General Assembly (GA) we held the first Geodesy 101 Short Course, where we gave an introduction to satellite gravimetry, GNSS processing and geodetic reference frames. We want to thank all of you who attended in-person or virtually, and made the short course a great experience! Please provide us feedback, if you have attended the short course here. At the GA, we were only able to scratch the surface of each topic, but there are a number …
Sean Daly is a (now retired) Canadian mining geologist with 40+ years of experience, who has dedicated his career to understanding the close relationship between mining, geology and society. His recent book “From the Erzgebirge to Potosi: A History of Geology and Mining Since the 1500’s” traces the history of mining and geology from the 1500’s including the Renaissance, the Industrial Revolution and modern times. The book spans his learnings and discoveries from the valuable silver mines of the Erzgebirge …
Jelle Assink, Senior Geophysicist at KNMI, takes us through the details of the various kinds of waves produced by the Hunga eruption in Tonga earlier this year… On January 15, 2022, a powerful volcanic eruption occurred in the Tonga archipelago in the Pacific Ocean when the submarine Hunga volcano exploded around 04:15 (UTC). This explosion marked the climactic end of an eruptive phase that started on 19 December 2021, after several years of quiescence. Never before have atmospheric waves from …
