A new study published today in the EGU journal The Cryosphere could improve our understanding of changes in the atmosphere–ice–ocean system and the mass balance of sea ice in a changing Arctic.
The European Geosciences Union is honouring 47 people at all stages of their careers who have made substantial contributions to the Earth, planetary, and space sciences.
This November EGU co-hosted an event to discuss how the geosciences can support the EU’s biodiversity targets, addressing specific issues relating to the Nature Restoration Law. Attended by several Members of the European Parliament and other key stakeholders, EGU’s Policy Manager Chloe Hill provides a reflection.
Applications are now open for individuals with an EU or Swiss passport, who are fluent in English, to work as a conference assistant at EGU23, in Vienna, Austria for our conference organiser Copernicus. Applications will be reviewed from 16 January 2023.
The EGU Outreach Committee has named three Public Engagement Grant winners this year: a project empowering school children to create their own environmental change maps, a model to explain how geophysics is done under the ocean and an investigative geoscience podcast !
The morphology and size of sediments influence erosion efficiency, sediment transport and the quality of aquatic ecosystem. In turn, the spatial evolution of sediment size provides information on the past dynamics of erosion and sediment transport. We have developed a new software which semi-automatically identifies and measures sediments based on 3D point clouds. This software is fast and efficient, offering a new avenue to measure the geometrical properties of large numbers of sediment grains.
Despite little evidence of regional Amazon rainforest dieback, many localised abrupt dieback events are observed in the latest state-of-the-art global climate models under anthropogenic climate change. The detected dieback events would still cause severe consequences for local communities and ecosystems. This study suggests that 7±5 % of the northern South America region would experience abrupt downward shifts in vegetation carbon for every degree of global warming past 1.5 °C.
The long-duration atmospheric impact of the Tonga eruption in January 2022 is a plume of water and sulfate aerosols in the stratosphere that persisted for more than 6 months. We study this evolution using several satellite instruments and analyse the unusual behaviour of this plume as sulfates and water first moved down rapidly and then separated into two layers. We also report the self-organization in compact and long-lived patches.
“Who are these men?!” he says, seeming genuinely baffled. I feel my shoulders rise towards my ears with tension as I wait for him to continue. The man is summarizing what his group, comprised solely of men, have arrived at during their group-discussion at the gender equality seminar we are taking. We have been presented with, I might say, “the usual” statistics for academic women. A prevalence, certainly, of sexual harassment and hostile working environments, but specifically highlighted also is …
In 1821, peat cutters discovered a body similar to a mummy, pinned down by two wooden stakes deep in the mud. The body’s face still held red hair and a beard, teeth preserved, and a hoop of willow wrapped around their throat. This wasn’t the dry, hot climate of Egypt but a cold and rain-sodded bog of Ireland. Later assessment suggested that this was the remains of a young man, and the likely victim of human sacrifice over 2000 years …
It is common to hear that a good illustration is better than a lengthy textual explanation, and we fully agree with that statement. We are used to retrieving information and understanding things through visual illustrations. In the scientific community, any paper comes with a number of plots to show the data, and diagrams to explain concepts, ideas or workflows. For example, a typical plot that hydrologists would produce to show the hydrological regime of a catchment is a bar chart …
