The website of the EGU/Copernicus open-access journal Solid Earth was relaunched with a new design during the EGU General Assembly last week. In addition, the former chief executive editor Fabrizio Storti stepped down. His successor is CharLotte Krawczyk who has been an executive editor since 2015.


EU Plenary

New EGU opportunity for early career scientists to be involved with policy

  • EGU news
  • 13 April 2018

European-based early career scientists (ECS) are invited to apply for the EGU’s ECS Policy Competition. The competition is open to all undergraduate or postgraduate (Masters/PhD) students and scientists who have received their highest degree (BSc, MSc, or PhD) within the past seven years. The winner of the competition will receive a ticket to a Dinner Debate in Brussels on the evening of September 26, 2018.

Analytically tractable climate–carbon cycle feedbacks under 21st century anthropogenic forcing

Around half of the carbon that humans emit into the atmosphere each year is taken up on land (by trees) and in the ocean (by absorption). We construct a simple model of carbon uptake that, unlike the complex models that are usually used, can be analysed mathematically. Our results include that changes in atmospheric carbon may affect future carbon uptake more than changes in climate. Our simple model could also study mechanisms that are currently too uncertain for complex models.


Climate of the Past

Random and externally controlled occurrences of Dansgaard–Oeschger events

The climate of the last glacial period was frequently interrupted by rapid warming events, the cause of which is still unknown. One open question is whether the occurrence of events is random or externally controlled. We studied the temporal characteristics of warm and cold phases using statistical null models and find that they are well described as random processes modulated by two different external climate factors. This may help distinguish physical mechanisms for rapid climate change.

Effects of climatic seasonality on the isotopic composition of evaporating soil waters

Evaporation causes the isotopic composition of soil water to become different from that of the original precipitation source. If multiple samples originating from the same source are available, they can be used to reconstruct the original source composition. However, soil water is influenced by seasonal variability in both precipitation sources and evaporation patterns. We show that this variability, if not accounted for, can lead to biased estimates of the precipitation source water.


Geoscientific Model Development

Crossing the chasm: how to develop weather and climate models for next generation computers?

Weather and climate models consist of complex software evolving in response to both scientific requirements and changing computing hardware. After years of relatively stable hardware, more diversity is arriving. It is possible that this hardware diversity and the pace of change may lead to an inability for modelling groups to manage their software development. This “chasm” between aspiration and reality may need to be bridged by large community efforts rather than traditional “in-house” efforts.

Natural Groundwater Quality: an underestimated and yet dangerous hazard.

Today I have the pleasure to interview Dr. Evangelos Tziritis, a brilliant scientist and a friend. He will talk to us about Natural groundwater quality hazard and its implications. This blog aim is to discuss Natural Hazards. Therefore, today we will focus on the natural component of water quality, disregarding anthropogenic sources. Evangelos is a Research Scientist at the Soil and Water Resources Institute of the Hellenic Agricultural Organization “Demeter”. His main research domain is focused on environmental hydrogeochemistry, as …

Imaggeo on Mondays: A volcanic point of view

It’s not every day that you can peer into a volcano, much less gaze out at the sky from the inside of one. The Algar do Carvão, or “the Cavern of Coal,” is one of the few places on Earth where you can explore the underground reaches of a volcanic site. The volcanic pit is found on the island of Terceira, part of the Azores archipelago. This collection of islands is an autonomous region of Portugal, located in the Atlantic …

Image of the Week — Biscuits in the Permafrost

In Svalbard, the snow melts to reveal a mysterious honeycomb network of irregular shapes (fig. 1). These shapes may look as though they have been created by a rogue baker with an unusual set of biscuit cutters, but they are in fact distinctive permafrost landforms known as ice-wedge polygons, and they play an important role in the global climate. Ice-wedge polygons: Nature’s biscuit-cutter In winter, cracks form when plummeting air temperatures cause the ground to cool and contract. O’Neill and …
