Effects of land use and anthropogenic aerosol emissions in the Roman Empire

Using the global aerosol–climate model ECHAM-HAM-SALSA, the effect of humans on European climate in the Roman Empire was quantified. Both land use and novel estimates of anthropogenic aerosol emissions were considered. We conducted simulations with fixed sea-surface temperatures to gain a first impression about the anthropogenic impact. While land use effects induced a regional warming for one of the reconstructions, aerosol emissions led to a cooling associated with aerosol–cloud interactions.

Electron pairing in mirror modes: surpassing the quasi-linear limit

The mirror mode starts as a zero-frequency ion fluid instability and saturates quasi-linearly at very low magnetic level, while forming extended magnetic bubbles. These trap the adiabatically bouncing electron component which forms pairs near the mirror points. The large pair anisotropy causes further growth beyond quasilinear level. Including pressure equilibrium gives and estimate of the required pair density.

Microbial community composition and abundance after millennia of submarine permafrost warming

Permafrost temperatures increased substantially at a global scale, potentially altering microbial assemblages involved in carbon mobilization before permafrost thaws. We used Arctic Shelf submarine permafrost as a natural laboratory to investigate the microbial response to long-term permafrost warming. Our work shows that millennia after permafrost warming by > 10 °C, microbial community composition and population size reflect the paleoenvironment rather than a direct effect through warming.


Geoscientific Model Development

The biophysics, ecology, and biogeochemistry of functionally diverse, vertically and horizontally heterogeneous ecosystems: the Ecosystem Demography model, version 2.2 – Part 1: Model description

Our paper describes the Ecosystem Demography model. This computer program calculates how plants and ground exchange heat, water, and carbon with the air, and how plants grow, reproduce and die in different climates. Most models simplify forests to an average big tree. We consider that tall, deep-rooted trees get more light and water than small plants, and that some plants can with shade and drought. This diversity helps us to better explain how plants live and interact with the atmosphere.

Enigmas at depth

Enigmas at depth

The Geodynamics 101 series serves to showcase the diversity of research topics and/or methods in the geodynamics community in an understandable manner. In this week’s Geodynamics 101 post, Marcel Thielmann, Senior Researcher at the University of Bayreuth, discusses the possible mechanisms behind the ductile deformation at great depths that causes deep earthquakes. Earthquakes are one of the expressions of plate tectonics that everybody seems to be familiar with. When I started studying geophysics, people used to ask me what exactly …

Imaggeo on Mondays: Civita di Bagnoregio – the dying town

On top of a steep cliff standing out from the surrounding countryside, lies the small town of Civita di Bagnoregio, one of the most famous villages of Italy. It is often called the dying town, although more recently people have started to refer to it as fighting to live. What this little town is fighting against is the threat of erosion, as its walls are slowly crumbling down. Located in central Italy, about a 100 km north of Rome, the …

The bad, the good and the unpredictable: living with volcanoes / part 2

Before continuing, if you haven’t read it yet, catch up with the first part of this blog article by clicking on this link. The good Living with volcanoes is not all bad. Volcanoes provide a wealth of natural resources in the form of building materials, hot springs, freshwater and fertile soil. However, there are more hidden aspects, which was the focus of a recent collaboration with an archaeologist. We believe that volcanoes and their landforms provide “cultural services”, which is …
