Open AccessModern temperatures in central–north Greenland warmest in past millennium
The Greenland Ice Sheet has a central role in the global climate system owing to its size, radiative effects and freshwater storage, and as a potential tip** point1. Weather stations show that the coastal regio...

Open AccessPast megadroughts in central Europe were longer, more severe and less warm than modern droughts
Megadroughts are notable manifestations of the American Southwest, but not so much of the European climate. By using long-term hydrological and meteorological observations, as well as paleoclimate reconstructi...

Open AccessEnhanced North Pacific deep-ocean stratification by stronger intermediate water formation during Heinrich Stadial 1
The deglacial history of CO2 release from the deep North Pacific remains unresolved. This is due to conflicting indications about subarctic Pacific ventilation changes based on various marine proxies, especially ...

North Pacific freshwater events linked to changes in glacial ocean circulation
There is compelling evidence that episodic deposition of large volumes of freshwater into the oceans strongly influenced global ocean circulation and climate variability during glacial periods1,2. In the North At...

Links between central Greenland stable isotopes, blocking and extreme climate variability over Europe at decadal to multidecadal time scales
The link between central Greenland stable oxygen isotopes, atmospheric blocking frequency and cold temperature extremes at decadal to multidecadal time scales is investigated using observed and proxy data as w...

Targeting transcription-coupled nucleotide excision repair overcomes resistance in chronic lymphocytic leukemia
Treatment resistance becomes a challenge at some point in the course of most patients with chronic lymphocytic leukemia (CLL). This applies to fludarabine-based regimens, and is also an increasing concern in t...

Open AccessLinkages between atmospheric blocking, sea ice export through Fram Strait and the Atlantic Meridional Overturning Circulation
As a key persistent component of the atmospheric dynamics, the North Atlantic blocking activity has been linked to extreme climatic phenomena in the European sector. It has also been linked to Atlantic multide...

Kolmogorov spectrum of renewable wind and solar power fluctuations
With increasing the contribution of renewable energies in power production, the task of reducing dynamic instability in power grids must also be addressed from the generation side, because the power delivered ...

Millennial-scale variability in Antarctic ice-sheet discharge during the last deglaciation
Two well-dated, high-resolution records of iceberg-rafted debris are presented that document variability in Antarctic Ice Sheet discharge during the last deglaciation.

Interannual to decadal summer drought variability over Europe and its relationship to global sea surface temperature
Interannual to decadal variability of European summer drought and its relationship with global sea surface temperature (SST) is investigated using the newly developed self calibrated Palmer drought severity in...

Changing climate states and stability: from Pliocene to present
We present a recently developed method of potential analysis of time series data, which comprises (1) derivation of the number of distinct global states of a system from time series data, and (2) derivation of...

A Construction of an Averaged Representation of Human Cortical Gyri Using Non-linear Principal Component Analysis
Because of the complex shape of human cortical gyri and great variation between individuals, development of effective representation schemes which allow establishment of correspondence between individuals, ext...

Holocene climate variability as derived from alkenone sea surface temperature and coupled ocean-atmosphere model experiments
Holocene climate modes are identified by the statistical analysis of reconstructed sea surface temperatures (SSTs) from the tropical and North Atlantic regions. The leading mode of Holocene SST variability in...

Stability of the glacial thermohaline circulation and its dependence on the background hydrological cycle
Different reconstructions of glacial sea-surface temperatures (SST) are used to force a hybrid coupled atmosphere–ocean model. The resulting glacial states differ in global salinity and temperature distributi...

Earth system models of intermediate complexity: closing the gap in the spectrum of climate system models
We propose a new perspective on the hierarchy of climate models which goes beyond the "classical" climate modeling pyramid that is restricted mainly to atmospheric processes. Most notably, we introduce a new ...

Charles S. Peirce on Creative Metaphor: A Case Study on the Conveyor Belt Metaphor in Oceanography
Within Charles Sanders Peirce's semiotical theory, twodifferent kinds of creative metaphorical reasoning inscience can be identified. One of these, the buildingof remainder metaphors, is especially important f...

Using Sulcal Basins for Analyzing Functional Activations Patterns in the Human Brain
In previous work, we have introduced the concept of sulcal basins. Sulcal basins are subdivisions of cortical folds that allow to establish a complete parcellation of the cortical surface into separate regions...

Automatical adaption of the stereotactical coordinate system in brain MRI datasets
Neuroanatomical and neurofunctional studies are often referenced to a high resolution MR brain dataset. To allow intersubject comparisons of cortical structures, one needs to remove the outer hulls of the brai...

A 1-D atmospheric energy balance model developed for ocean modelling
We present a simple, deterministic energy balance model. The model is designed to represent the atmospheric component of the coupled atmosphere-ocean system. It is a one dimensional, global model with time and...
