- 30 April 2021
Many thanks to all vEGU21 participants and volunteers who have ensured that the EGU General Assembly 2021 was a productive and stimulating experience—despite a few unexpected bumps along the way!
Flies grow bigger up north: insect size a promising new proxy for palaeoclimate
- EGU news
- 29 April 2021
Can the body size of ancient flies reveal past temperatures? Scientists may have extended a proxy for past climates back millions of years. The results will be presented at the European Geosciences Union (EGU) General Assembly 2021, which is taking place from 19-30 April 2021.
‘Picture A Scientist’ screening extended!

High-frequency monitoring of anomalous methane point sources with multispectral Sentinel-2 satellite observations
- Atmospheric Measurement Techniques
- DOI 10.5194/amt-14-2771-2021
- 31 May 2021
Satellites can detect methane emissions by measuring sunlight reflected from the Earth’s surface and atmosphere. Here we show that the European Space Agency’s Sentinel-2 twin satellites can be used to monitor anomalously large methane point sources around the world, with global coverage every 2–5 days and 20 m spatial resolution. We demonstrate this previously unreported capability through high-frequency Sentinel-2 monitoring of two strong methane point sources in Algeria and Turkmenistan.
JlBox v1.1: a Julia-based multi-phase atmospheric chemistry box model
- Geoscientific Model Development
- DOI 10.5194/gmd-14-2187-2021
- 28 May 2021
As our knowledge and understanding of atmospheric aerosol particle evolution and impact grows, designing community mechanistic models requires an ability to capture increasing chemical, physical and therefore numerical complexity. As the landscape of computing software and hardware evolves, it is important to profile the usefulness of emerging platforms in tackling this complexity. With this in mind we present JlBox v1.1, written in Julia.
Sudden large-volume detachments of low-angle mountain glaciers – more frequent than thought?
- The Cryosphere
- DOI 10.5194/tc-15-1751-2021
- 26 May 2021
Hardly recognized so far, giant catastrophic detachments of glaciers are a rare but great potential for loss of lives and massive damage in mountain regions. Several of the events compiled in our study involve volumes (up to 100 million m3 and more), avalanche speeds (up to 300 km/h), and reaches (tens of kilometres) that are hard to imagine. We show that current climate change is able to enhance associated hazards. For the first time, we elaborate a set of factors that could cause these events.

EGU Teacher-Scientist Pairing Scheme: supporting geoscience education in schools
- GeoLog – EGU official blog
- posted 2 hours ago
For the vEGU21 General Assembly, the EGU Education & Outreach Committees tried something new. They connected school teacher, Hélder Pereira, with seismologist, Susana Custódio, to create and teach a lesson plan on a topic relevant to Hélder’s classroom curriculum: the origin of the South American volcanic gaps. The lesson was live streamed online from Hélder’s class in Algarve, Portugal, with Scientist, Susana, joining virtually from the University of Lisbon. In addition to Hélder’s curious students, over 40 equally intrigued EGU …
Life on the (Ice) Edge: Antarctic Seabirds and Sea Ice
- Cryospheric Sciences
- posted 3 hours ago
The vast expanse of Antarctic sea-ice may appear inhospitable at first, but the region supports one of the most productive ecosystems on Earth. Amongst the organisms that call Antarctica home, certain seabird species have become so well adapted to the harsh conditions that they not only survive in the region, but flourish. Like all Antarctic organisms, seabirds are intricately linked to the continent’s sea ice, dependant on it for survival. With a warming climate, sea ice conditions are changing, with …
The Sassy Scientist – Race to the Deadline

After snoozing their alarm for the 50th time, Alex gets started with their day. They should be writing their thesis first thing after breakfast, but instead they write to the Sassy Scientist: How do you manage to meet writing deadlines as a PhD student? Dear Alex, Ah! You have reached the writing stage. I assume then your pin board is full of post-it notes with goals for ‘next week’. But what is this mysterious next week? Which next week? And …
