Plateaus and jumps in the atmospheric radiocarbon record – potential origin and value as global age markers for glacial-to-deglacial paleoceanography, a synthesis
- Climate of the Past
- DOI 10.5194/cp-16-2547-2020
- 21 January 2021
The dating technique of 14 C plateau tuning uses U/Th-based model ages, refinements of the Lake Suigetsu age scale, and the link of surface ocean carbon to the globally mixed atmosphere as basis of age correlation. Our synthesis employs data of 20 sediment cores from the global ocean and offers a coherent picture of global ocean circulation evolving over glacial-to-deglacial times on semi-millennial scales to be compared with climate records stored in marine sediments, ice cores, and speleothems.
Long-term deposition and condensation ice-nucleatingparticle measurements from four stations across the globe
- Atmospheric Chemistry and Physics
- DOI 10.5194/acp-20-15983-2020
- 20 January 2021
Long-term ice-nucleating particle (INP) data are presented from four semi-pristine sites located in the Amazon, the Caribbean, Germany and the Arctic. Average INP concentrations did not differ by orders of magnitude between the sites. For all sites short-term variability dominated the time series, which lacked clear trends and seasonalities. Common drivers to explain the INP levels and their variations could not be identified, illustrating the complex nature of heterogeneous ice nucleation.
Emergent constraints on equilibrium climate sensitivity in CMIP5: do they hold for CMIP6?
- Earth System Dynamics
- DOI 10.5194/esd-11-1233-2020
- 19 January 2021
As an important measure of climate change, the Equilibrium Climate Sensitivity (ECS) describes the change in surface temperature after a doubling of the atmospheric CO 2 concentration. Climate models from the Coupled Model Intercomparison Project (CMIP) show a wide range in ECS. Emergent constraints are a technique to reduce uncertainties in ECS with observational data. Emergent constraints developed with data from CMIP phase 5 show reduced skill and higher ECS ranges when applied to CMIP6 data.
Brief communication: Heterogenous thinning and subglacial lake activity on Thwaites Glacier, West Antarctica
- The Cryosphere
- DOI 10.5194/tc-14-4603-2020
- 18 January 2021
The West Antarctic Ice Sheet has long been considered geometrically prone to collapse, and Thwaites Glacier, the largest glacier in the Amundsen Sea, is likely in the early stages of disintegration. Using observations of Thwaites Glacier velocity and elevation change, we show that the transport of ~2 km 3 of water beneath Thwaites Glacier has only a small and transient effect on glacier speed relative to ongoing thinning driven by ocean melt.

TS Must Read – Ramsay (1980): Shear zone geometry: a review
- Tectonics and Structural Geology
- posted 4 hours ago
Ramsay’s 1980 important contribution is a practical and theoretical handbook about shear zones, where the reader can find a detailed classification of shear zones, their description, and mathematical explanation. A definition of the concept of shear zones opens the article, followed by the shear zones classification into three types, namely brittle (e.g., Fig. 1a), brittle-ductile (e.g., Fig. 1b), and ductile. For each shear zone, Ramsay lists its characteristic geometrical features according to their displacement field, which is in turn determined …
Rift linkage and rotating microplates

2020 left your head spinning? This week Derek Neuharth from GFZ Potsdam introduces us to the spinning microplates that can be found in extensional plate boundaries such as the East African Rift System and the East Pacific Rise. Divergent plate boundaries Microplates are enigmatic features that form in the boundaries between tectonic plates. Generally, plate boundary dynamics are divided into three types: 1) convergent boundaries where plates collide (e.g., Andes subduction zone; Sobolev & Babeyko, 2005), 2) transform boundaries where …

Dear readers of the EGU Climate: Past, present and future blog. We hope you are having a good start to the New Year. Last year we faced a multitude of challenges due to the pandemic. Hopefully, by the end of 2021, the vaccination campaign will help combat the pandemic, and allow us to go back to some semblance of normality; fingers crossed!
