New computer model simulations identify widespread changes in climate variability under sustained anthropogenic forcing. Researchers ran multiple simulations over the period of 1850-2100, working with a “business-as-usual” scenario for strong emissions of greenhouse gases over the 21st century. The study was published today in Earth System Dynamics.
The European Geosciences Union is honouring 50 people at all stages of their careers who have made substantial contributions to the Earth, planetary, and space sciences.
The EGU Outreach Committee has named three Public Engagement Grant winners this year: a card game of geological time, space weather teaching kits for blind and visually impaired students and a musical about climate change!
Venture into space! Learn more about why we study space science with Joby Hollis, meet the Planetary Sciences Division ECS rep Joshua Dreyer and submit your abstract to EGU22!
The Union is hiring an Events Co-ordinator to support our Programme Committee in planning the annual General Assembly and other EGU events run throughout the year. Applications will be reviewed from 16 November 2021 until the position is filled.
The Australian continent is included in global assessments of the carbon cycle such as the global carbon budget, yet the performance of dynamic global vegetation models (DGVMs) over Australia has rarely been evaluated. We assessed simulations by an ensemble of dynamic global vegetation models over Australia and highlighted a number of key areas that lead to model divergence on both short (inter-annual) and long (decadal) timescales.
Taking a single flood disaster in Lishui city as an example, a rapid and refined assessment of economic loss is studied and verified, which can effectively simulate the distribution of loss ratio and loss value. It includes the construction of land use type and value based on data fusion and an expert questionnaire survey, the fitting and calibration of vulnerability curves based on an existing database and disaster loss reporting, and estimation of loss ratio and loss value by spatial analysis.
Metal layers occur in the MLT region (80–120 km) from the ablation of cosmic dust. The latest lidar observations show these metals can reach a height approaching 200 km, which is challenging to explain. We have developed the first global simulation incorporating the full life cycle of metal atoms and ions. The model results compare well with lidar and satellite observations of the seasonal and diurnal variation of the metals and demonstrate the importance of ion mass and ion-neutral coupling.
2021 was yet another year of uncertainty, with many changes and disruptions to our plans, activities, and goals. EGU’s science for policy programme was no exception to this with the Science for Policy Pairing Scheme and annual Science for Policy Event taking a back seat. We hope that 2022 will not only bring new activities but also rekindle those that were put on hold as a result of the pandemic. This blog post will kick-off the New Year by outlining …
The #EGU22 abstract submission is almost here – less than a week until it closes on January 12th at 13:00 CET. So it is time to wrap up our sessions in the spotlight with a last highlight – the interdisciplianry session GMPV9.3 “Volcano-glacier interactions: Arctic, Antarctic, and globally“. This session is organized by a diverse team consisting of Eva Eibl, Iestyn Barr, Adelina Geyer and Gioachino Roberti. So if you are interested in volcano-glacier interactions you should give it a …
The idea that the Pleistocene glaciation was caused by a late Cenozoic rise of mountain ranges had been developed since the mid 19th century. Although this original idea did not hold, new arguments for a relation between a late Cenozoic uplift of mountains and global cooling were presented from the 1970s onward. These arguments focused on how increased surface elevations would affect the albedo, the circulation of the atmosphere, and chemical weathering, which acts as a carbon dioxide sink. A …
