New study: Fracking prompts global spike in atmospheric methane

  • Press release
  • 14 August 2019

As methane concentrations increase in the Earth’s atmosphere, chemical fingerprints point to a probable source: shale oil and gas, according to new Cornell University research published today in Biogeosciences, a journal of the European Geosciences Union.

Higher education teaching of geoscience: how can the EGU help?

  • EGU news
  • 8 July 2019

EGU’s Committee on Education aims to provide support for higher education, from organising workshops to providing networking opportunities for all those teaching geoscience in higher education. We invite PhD students, postgraduates, research fellows, academic staff and any others teaching geoscience in higher education to fill in a short survey to help us understand the role EGU could play in further supporting higher education.

Hybrid-Vlasov modelling of nightside auroral proton precipitation during southward interplanetary magnetic field conditions

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?

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)

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

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.

EGU General Assembly 2020: Apply to be our next artist in residence!

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 …

Did you know? – Proglacial lakes accelerate glacier retreat!

In a global context, New Zealand’s small mountain glaciers often get overlooked and yet they are a beautiful part of New Zealand’s landscape. They are the water towers for the South Island and an essential part of its tourism, thanks to a few undeniable heroes (Frans Josef and Fox Glaciers), but sadly, they may not be as prominent in the future. In this post we review the state of modern glaciation in New Zealand, explain why glacier-lake interactions are important …
