EGU has awarded funding to three science journalists to cover particular geoscience stories of interest over the next 12 months. The funding has been awarded to Georg Koszulinski, Stefano Valentino and Carl Smith.
The EGU Outreach Committee has named three Public Engagement Grant winners this year: a project that combines the knowledge of indigenous peoples and researchers when looking at water protection, a fun geoscience games booklet designed for early years children and listening benches that tell soil science stories to anyone who decides to sit and listen.
As part of its #ShareYourScience initiative, EGU sought feedback from journalists in Europe and beyond about their experiences working with scientists. According to the survey respondents, a lack of time and ambiguity over discussing their work before publication were other reasons that scientists shared while declining media interviews.
The European Union’s proposed Nature Restoration Law aims to provide essential guidance and support to restore ecosystems, habitats and species across the EU’s land and sea areas. The proposed legislation comes at a critical moment when, despite EU and international efforts, biodiversity loss and the degradation of ecosystems continues at an alarming rate.
Thanks to the enthusiastic efforts of our members and volunteers, EGU23 reached an amazing 18,831 people at the General Assembly, both in Vienna and online!
This paper presents a technique for understanding the causes of long-term changes in stratospheric composition. By using N2O as a proxy for stratospheric circulation in the model used to calculated trends, it is possible to separate the effects of dynamics and chemistry on observed trace gas trends. We find that observed HCl increases are due to changes in the stratospheric circulation, as are O3 decreases above 30 hPa in the Northern Hemisphere.
The mesosphere or lower thermosphere region of the atmosphere borders the edge of space. It is subject to extreme ultraviolet photons and charged particles from the Sun and atmospheric gravity waves from below, which tend to break in this region. The pressure is very low, which facilitates chemistry involving species in excited states, and this is also the region where cosmic dust ablates and injects various metals. The result is a unique and exotic chemistry.
The presence of crevasses in Antarctica influences how the ice sheet behaves. It is important, therefore, to collect data on the spatial distribution of crevasses and how they are changing. We present a method of mapping crevasses from satellite radar imagery and apply it to 7.5 years of images, covering Antarctica’s floating and grounded ice. We develop a method of measuring change in the density of crevasses and quantify increased fracturing in important parts of the West Antarctic Ice Sheet.
Ladies and gentlemen, disaster movie aficionados, and geological enthusiasts, it’s time to revisit the epic showdown that was the Geo-Movie Cup 2023. This year, the competition reached unprecedented heights, welcoming new movies into the mix, adding Instagram as a polling platform, and ultimately crowning “Dante’s Peak” as the winner. Let’s dive in and recap this year’s cup. Instagram Joins the Game One of the most exciting developments in this year’s competition was the inclusion of Instagram as a platform for …
Today, 3 November, is globally recognized as the International Day for Biosphere Reserves. The first edition of this observance day was marked last year, with UNESCO urging our relationship with nature needed “a radical rethink.” As Audrey Azoulay, Director-General of UNESCO explains, “The logic is simple: to improve our relationship with nature, we must first improve our understanding of how we affect the living world that sustains us – and vice versa.” A good place to understanding biosphere reserves is …
Particle Precipitation High energy particles (e.g. electrons and protons) that precipitate at high latitudes can alter the chemical composition of the atmosphere by different photochemical reactions. This mainly happens due to primary collision processes and subsequent ion and neutral-chemistry reactions. Such reactions ordered by increasing energy are, for example, excitation, photo-dissociation, photo-ionization and dissociative ionization. These particles can come from various sources in outer space, accelerated by different processes to varied energies, and they affect different altitude ranges of the …
