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.
Professor Chris King, chair of EGU’s Education Committee and a champion of geoscience education, died late last week.
Members of the media, public information officers and science bloggers are now invited to register for the meeting free of charge. EGU22 will be held from 23-27 May, 2022 both in-person (Vienna, Austria) and online.
In this study, we investigate the chemical diversity and abundance of microbial lipids as markers of organic matter sources in the deepest points of the Atacama Trench sediments and compare them to similar lipid stocks in shallower surface sediments and in the overlying water column. We evaluate possible organic matter provenance and some potential chemical adaptations of the in situ microbial community to the extreme conditions of high hydrostatic pressure in hadal realm.
Simulations by six Earth-system models of geoengineering by introducing sulfuric acid aerosols into the tropical stratosphere are compared. A robust impact on the northern wintertime North Atlantic Oscillation is found, exacerbating precipitation reduction over parts of southern Europe. In contrast, the models show no consistency with regard to impacts on the Quasi-Biennial Oscillation, although results do indicate a risk that the oscillation could become locked into a permanent westerly phase.
A large amount of marine litter, such as plastics, is located on or around beaches. Both the total amount of this litter and its transport are poorly understood. We investigate this by training a machine learning model with data of clean-up efforts on Dutch beaches between 2014 and 2019, obtained by about 14 000 volunteers. We find that Dutch beaches contain up to 30 000 kg of litter, largely depending on tides, oceanic transport, and how exposed the beaches are.
Every division within the European Geosciences Union is led by a senior and junior representative, who oversee the happenings within their respective divisions. The senior representative of the Cryosphere Division is Carleen Tijm-Reijmer, who we’ve managed to track down here at EGU! We ask Carleen to explain her role within EGU and the CR Division. Please tell us a little bit about yourself! I am an associate professor at Utrecht University (in the Netherlands), at the Institute for Marine and …
For this year’s Photo Contest, EGU received scores of amazing images capturing a broad spectrum of the geosciences. After the selection committee whittled the field down to 10 finalists, members have been voting for their favourites throughout EGU22’s week-long conference. After an enthusiastic response from our online and on-site voters, we are now ready and very excited to announce the winners! Congratulations to these superb photographers!

Live from the EGU assembly, from an anonymous chair in an anonymous room in the Vienna International Centre, during an anonymous session on some geoscience-related topic, my commitment of reporting the truth as-is does not stop. Siri has recently asked a very practical question concerning the organisation of your EGU experience: How do you make your own personal programme for EGU without screaming in frustration? Dear Siri, You don’t. You just don’t. That would require a smoothly working website. As …
