A range of outcomes: the combined effects of internal variability and anthropogenic forcing on regional climate trends over Europe

Past and future climate change at regional scales is a result of both human influences and natural (internal) variability. Here, we provide an overview of recent advances in climate modeling and physical understanding that has led to new insights into their respective roles, illustrated with original results for the European climate. Our findings highlight the confounding role of internal variability in attribution, climate model evaluation, and accuracy of future projections.

Nitrous oxide (N2O) synthesis by the freshwater cyanobacterium Microcystis aeruginosa

We show, for the first time, that pure cultures of the cyanobacterium Microcystis aeruginosa can synthesize the potent greenhouse gas N2O using nitrite as substrate. Our findings have broad environmental implications because M. aeruginosa is globally found in freshwater ecosystems and is often the dominant species found in algae blooms. Further research is now needed to determine the occurrence and significance of N2O emissions from ecosystems rich with M. aeruginosa.

The dispersal of fluvially discharged and marine, shelf-produced particulate organic matter in the northern Gulf of Mexico

Terrestrial organic matter (TerrOM) is transported to the ocean by rivers, where its burial can potentially form a long-term carbon sink. This burial is dependent on the type and characteristics of the TerrOM. We used bulk sediment properties, biomarkers, and palynology to identify the dispersal patterns of plant-derived, soil–microbial, and marine OM in the northern Gulf of Mexico and show that plant-derived OM is transported further into the coastal zone than soil and marine-produced TerrOM.

How to run your own event with our pop-up networking scheduler at EGU23

Attendees at the EGU23 General Assembly can organise their own events using the the Pop-up Networking Scheduler! Registered participants can use the online tool to organise networking events both inside, outside, and beyond the conference centre – including virtually. All events organised using the Pop-up Networking Scheduler will appear on the conference programme. The scheduler is designed for anyone who wants to run their own event, of any kind, from small to big, during the conference week. Events could be …

How does slab tearing evolve?

Slab tearing refers to the gradual propagation of the break-off of a subducting plate. As observed in numerous modern and ancient convergent tectonic settings, the growth of the tear “window” in the downgoing plate has strongly influenced various geologic and geodynamic processes, such as depocenter migration of foreland basins, uplift rates in mountain ranges, earthquakes, volcanism, and flow patterns in the upper mantle. However, our understanding of the dynamics of slab break-off and tearing, especially in non-collisional environments, is still …

New spheres of scientific publishing

Many of you have noticed that EGUsphere went online, the new preprint repository hosted by EGU, as a service for the entire geosciences community. This repository can be used by any geoscientist to deposit their preprint even those that are not submitted to Copernicus journals. If you submit a preprint, your manuscript will receive a DOI number, the EGUsphere logo and – most importantly – a discussion page for comments from the community. In case you submitted your preprint to …
