Short summary
The Shanxi Rift is a young, active rift in northern China that formed atop a Proterozoic orogen. The impact of these structures on active rift faults is poorly understood. Here, we quantify the landscape response to active faulting and compare it with published maps of inherited structures. We find that inherited structures played an important role in the segmentation of the Shanxi Rift and in the development of rift interaction zones, which are the most active regions in the Shanxi Rift.

Reconstructions of past glaciations tell us about how ice sheets grow and retreat. In this study, we use speleothems (cave deposits, e.g., stalagmites) in the British Isles to help constrain the extent of past glaciations both in time and space. Speleothems require liquid water to grow, and therefore, their presence indicates the absence of ice above the cave. By dating these speleothems we can improve existing reconstructions of past ice sheets.

The planetary boundary framework characterizes major risks of destabilization of the Earth system. We use the comprehensive Earth system model POEM to study the impact of the interacting boundaries for climate change and land system change. Our study shows the importance of long-term effects on carbon dynamics and climate, as well as the need to investigate both boundaries simultaneously and to generally keep both boundaries within acceptable ranges to avoid a catastrophic scenario for humanity.

Short summary
The formation of major strike-slip faults remains enigmatic in the framework of plate tectonics. Using 3D finite element models, we show that the co-existence of extension and shortening (at a high angle with the extension direction) and a weak lithosphere (e.g high geotherm) can trigger normal faulting and strike-slip faulting. Our results are compared to the Aegean example where strike slip faults (e.g. North Anatolian fault) and normal faults (e.g. Corinth rift) work together.

One limit of planetary habitability is defined by the threshold of global glaciation. If Earth cools, growing ice cover makes it brighter, leading to further cooling, since more sunlight is reflected, eventually leading to global ice cover (Snowball Earth). We study how much carbon dioxide is needed to prevent global glaciation in Earth's history given the slow increase in the Sun's brightness. We find an unexpected change in the characteristics of climate states close to the Snowball limit.

Short summary
Continental crust comprises bodies of varying strength, formed through numerous tectonic events. When subject to extension, these areas produce distinct rift and fault systems. We use 3D models to examine how rifts form above
strongand
weakareas of crust. We find that faults become more developed in weak areas. Faults are initially stopped at the boundaries with stronger areas before eventually breaking through. We relate our model observations to rift systems globally.

In this study, we couple the well-established and comprehensively validated state-of-the-art dynamic LPJmL5 global vegetation model to the CM2Mc coupled climate model (CM2Mc-LPJmL v.1.0). Several improvements to LPJmL5 were implemented to allow a fully functional biophysical coupling. The new climate model is able to capture important biospheric processes, including fire, mortality, permafrost, hydrological cycling and the the impacts of managed land (crop growth and irrigation).

Short summary
We present the technical implementation of a coarse-resolution coupling between an ice sheet model and an ocean model that allows one to simulate ice–ocean interactions at timescales from centuries to millennia. As ice shelf cavities cannot be resolved in the ocean model at coarse resolution, we bridge the gap using an sub-shelf cavity module. It is shown that the framework is computationally efficient, conserves mass and energy, and can produce a stable coupled state under present-day forcing.

The events of the Permian — the orogenies, biospheric turnovers, icehouse and greenhouse antitheses, and Mars-analog lithofacies — boggle the imagination and present us with great opportunities to explore Earth system behavior. Here we outline results of workshops to propose continuous coring of continental Permian sections in western (Anadarko Basin) and eastern (Paris Basin) equatorial Pangaea to retrieve continental records spanning 50 Myr of Earth's history.

The Younger Dryas occurred ~13 ka BP and is an iconic millennial-scale climate anomaly. However, the cause of the event is still ambiguous. Here, we propose that the event was triggered by a large, sulfur-rich eruption of the Laacher See volcano (Germany). The eruption's direct (sulfate aerosol-induced) cooling effects lasted less than 5 years, and we suggest these were amplified and extended by a sea-ice–ocean circulation positive feedback, leading to the event's characteristic features.

To get a deeper understanding of the various evolutionary changes, which took place during the Devonian (419 to 359 Ma), we here use a coupled climate model to investigate the sensitivity of the Devonian climate to changes in orbital forcing, continental configuration and vegetation cover. Our results are summarised by best-guess simulations for the Early, Middle and Late Devonian showing a decreasing temperature trend in accordance with the reconstructed decreasing atmospheric CO2.

Short summary
During at least two phases in its past, Earth was more or less covered in ice. These “snowball Earth” events probably started suddenly upon undercutting a certain threshold in the carbon-dioxide concentration. This threshold can vary considerably under different conditions. In our study, we find the thresholds for different distributions of continents, geometries of Earth’s orbit, and volcanic eruptions. The results show that the threshold might have varied by up to 46 %.
During at least two phases in its past, Earth was more or less covered in ice. These “snowball...
