Artists: apply for a residency at Europe’s largest geoscience conference

  • EGU news
  • 18 September 2019

For the third year in a row, the European Geosciences Union (EGU) will be hosting artists at its annual General Assembly. We are now opening a call for artists to apply for a residency at the 2020 conference, which is taking place in Vienna, Austria from 3-8 May 2020. The deadline for applications is 1 December.

Burgundy wine grapes tell climate story, show warming accelerated in past 30 years

  • Press release
  • 29 August 2019

A newly published series of dates of grape harvest covering the past 664 years is the latest line of evidence confirming how unusual the climate of the past 30 years has been. The record shows wine grapes in Burgundy, eastern France, have been picked 13 days earlier on average since 1988 than they were in the previous six centuries, pointing to the region’s hotter and drier climate in recent years. The results are now published in Climate of the Past.

The EGU has launched its latest international not-for-profit scientific publication. Weather and Climate Dynamics is an open-access, two-stage journal with open review, following the model of other EGU journals, and is published by Copernicus Publications.


A poster session at the EGU 2018 General Assembly

Open letter to funding agencies regarding presentations at EGU meetings

  • EGU news
  • 20 August 2019

The EGU has issued an open letter to funding agencies and evaluation committees with information on the assessment of presentations given at its scientific meetings. The letter details the three presentation types given at EGU General Assembly and states that the selection of the type of presentation is not based on any evaluation of the scientific value of the contribution. As highlighted in a previous EGU statement, the letter also emphasises that there is no distinction regarding the standing, quality or prestige of oral, poster, or PICO presentations.

Benchmarking the predictive capability of hydrological models for river flow and flood peak predictions across over 1000 catchments in Great Britain

We evaluated four hydrological model structures and their parameters on over 1100 catchments across Great Britain, considering modelling uncertainties. Models performed well for most catchments but failed in parts of Scotland and south-eastern England. Failures were often linked to inconsistencies in the water balance. This research shows what conceptual lumped models can achieve, gives insights into where and why these models may fail, and provides a benchmark of national modelling capability.

Physical constraints for respiration in microbial hotspots in soil and their importance for denitrification

A combination of gas chromatography and X-ray CT reveals the microscale processes that govern soil respiration. Aerobic and anaerobic respiration in microbial hotspots depends not only on the quality and quantity of soil organic matter, but also on the spatial distribution of hotspots. Denitrification kinetics are mainly governed by hotspot architecture due to local competition for oxygen during growth. Cumulative behavior is mainly governed by water saturation due to the overall supply with O2.

Estimating Greenland tidewater glacier retreat driven by submarine melting

The ocean’s influence on the retreat of Greenland’s tidewater glaciers is a key factor determining future sea level. By considering observations of ~200 glaciers from 1960, we find a significant relationship between retreat and melting in the ocean. Projected forwards, this relationship estimates the future evolution of Greenland’s tidewater glaciers and provides a practical and empirically validated way of representing ice–ocean interaction in large-scale models used to estimate sea level rise.

Global-scale human pressure evolution imprints on sustainability of river systems

A simple and effective index for the quantitative estimation of the evolution of human pressure on rivers at global scale is proposed. This index, based on nightlights and river discharge data, shows a significant increase from 1992 to 2013 worldwide. The most notable changes are found in river basins across Africa and Asia, where human pressure on rivers is growing markedly. This index identifies priority areas that can be targeted for the implementation of mitigation strategies and plans.

Featured catchment series: Disentangling the ecohydrology of a tropical hotspot!

Zhurucay Ecohydrological Observatory: Critical zone observations at the top of the Andes! A natural laboratory of tropical alpine ecohydrology Tropical alpine ecosystems, known as the Páramo, extend to high elevations (3,000-5,000 m a.s.l.) mainly through the northern Andes of South America from Venezuela to northern Peru. Given their geographical location and elevation, Páramo areas are exposed to high energy inputs from solar radiation that can critically stress vegetation, soils, and water resources. Moreover, the highly organic nature of their soils …

Imaggeo on Mondays: The glacier surviving climate change

Human impacts on the climate are nowadays clearly discernible, and the changes to our climate that previously happened in geologic time scales are currently happening during the span of a human lifetime. Our planet is warming and temperature today is now more than 1°C higher than it was in the pre-industrial world and rises by about 0.15-0.2°C on average each decade. The dramatic effects of this rapid climate change are appearing right now: the increasing temperatures are melting glaciers and …
