New EGU journal: Weather and Climate Dynamics
- EGU news
- 23 August 2019
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.
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.
New study: Fracking prompts global spike in atmospheric methane

Hybrid-Vlasov modelling of nightside auroral proton precipitation during southward interplanetary magnetic field conditions
- Annales Geophysicae
- DOI 10.5194/angeo-37-791-2019
- 10 September 2019
When the terrestrial magnetic field is disturbed, particles from the near-Earth space can precipitate into the upper atmosphere. This work presents, for the first time, numerical simulations of proton precipitation in the energy range associated with the production of aurora (∼1–30 keV) using a global kinetic model of the near-Earth space: Vlasiator. We find that nightside proton precipitation can be regulated by the transition region between stretched and dipolar geomagnetic field lines.
How can geologic decision-making under uncertainty be improved?
- Solid Earth
- DOI 10.5194/se-10-1469-2019
- 3 September 2019
In this paper, we outline the key insights from decision-making research about how, when faced with uncertainty, humans constrain decisions through the use of heuristics (rules of thumb), making them vulnerable to systematic and suboptimal decision biases. We also review existing strategies to debias decision-making that have applicability in the geosciences, giving special attention to strategies that make use of information technology and artificial intelligence.
Improved methodologies for Earth system modelling of atmospheric soluble iron and observation comparisons using the Mechanism of Intermediate complexity for Modelling Iron (MIMI v1.0)
- Geoscientific Model Development
- DOI 10.5194/gmd-12-3835-2019
- 2 September 2019
MIMI v1.0 was designed for use within Earth system models to simulate the 3-D emission, atmospheric processing, and deposition of iron and its soluble fraction. Understanding the iron cycle is important due to its role as an essential micronutrient for ocean phytoplankton; its supply limits primary productivity in many of the world’s oceans. Human activity has perturbed the iron cycle, and MIMI is capable of diagnosing many of these impacts; hence, it is important for future climate studies.
CO2 effects on diatoms: a synthesis of more than a decade of ocean acidification experiments with natural communities
- Ocean Science
- DOI 10.5194/os-15-1159-2019
- 28 August 2019
Diatoms are a group of phytoplankton species responsible for ~ 25% of primary production on Earth. Ocean acidification (OA) could influence diatoms but the key question is if they become more or less important within marine food webs. We synthesize OA experiments with natural communities and found that diatoms are more likely to be positively than negatively affected by high CO2 and larger species may profit in particular. This has important implications for ecosystem services diatoms provide.

Imaggeo on Mondays: The glacier surviving climate change
- GeoLog – EGU official blog
- posted 22 hours ago
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 …
NP Interviews: the 2019 Lewis Fry Richardson Medal Shaun Lovejoy
- Nonlinear Processes in Geosciences
- posted 1 day ago
Today’s NP Interviews hosts the Lewis Fry Richardson Medal Shaun Lovejoy. Shaun has degrees in physics from Cambridge and McGill University; he has been a McGill professor since 1985. For four decades, he has developed fractal, scaling ideas in the geosciences, contributing to advances in cascade processes, multifractals, anisotropic scale invariance, space-time multifractal modeling as well as to the empirical establishment of wide range atmospheric scaling. He co-founded the Nonlinear Processes in Geosciences Division at the EGU, and the Nonlinear …
EGU General Assembly 2020: Apply to be our next artist in residence!
- GeoLog – EGU official blog
- posted 3 days ago
Calling all artists interested in the geosciences! For the third year in a row, the European Geosciences Union (EGU) will be providing artist in residence opportunities at its annual General Assembly. Our residency programme provides artists with an opportunity to engage with scientific research in a dynamic setting and be inspired by new scientific discoveries. Researchers, on the other hand, can discover new and creative ways of making their work more accessible to the public through interacting with EGU artists …
