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.



Airplane contrails

Climate impact of clouds made from airplane contrails may triple by 2050

  • Press release
  • 27 June 2019

In the right conditions, airplane contrails can linger in the sky as contrail cirrus – ice clouds that can trap heat inside the Earth’s atmosphere. Their climate impact has been largely neglected in global schemes to offset aviation emissions, even though contrail cirrus have contributed more to warming the atmosphere than all CO2 emitted by aircraft since the start of aviation. A new study published in Atmospheric Chemistry and Physics has found that, due to air traffic activity, the climate impact of contrail cirrus will be even more significant in the future, tripling by 2050.

Summary and synthesis of Changing Cold Regions Network (CCRN) research in the interior of western Canada – Part 1: Projected climate and meteorology

This article examines future atmospheric-related phenomena across the interior of western Canada associated with abusiness-as-usualclimate scenario. Changes in large-scale atmospheric circulation and extent of warming vary with season, and these generally lead to increases, especially after mid-century, in factors associated with winter snowstorms, freezing rain, drought, forest fires, as well as atmospheric forcing of spring floods, although not necessarily summer convection.

A low-cost device for measuring local magnetic anomalies in volcanic terrain

Our knowledge of the Earth’s magnetic field arises from magnetic signals stored in lavas. In rugged volcanic terrain, however, the magnetization of the underlying flows may influence the magnetic field as recorded by newly formed flows on top. To measure these local magnetic anomalies, we developed a low-cost field magnetometer with superior accuracy and user-friendliness. The first measurements on Mt. Etna show local magnetic variations that are much larger than expected.

Fault-controlled dolomitization in the Montagna dei Fiori Anticline (Central Apennines, Italy): record of a dominantly pre-orogenic fluid migration

The dolomitized intervals of the Lower Jurassic deposits exposed in the Montagna dei Fiori Anticline (Central Apennines, Italy) have been investigated. Accordingly, two fault-related dolomitization events were recognised and interpreted as having occurred before and during the Apenninic orogeny. The analyses suggest significant involvement of evaporitic fluids in both events, most likely derived from the underlying Upper Triassic Burano Formation in the detachment level.

Load-resistance analysis: an alternative approach to tsunami damage assessment applied to the 2011 Great East Japan tsunami

It is known that fragility functions reflect localities (building design standards and topography) and flow velocity is more important, as damage might occur before flow depth reaches its maximum value. This research demonstrates that it is possible to accurately predict building damage by considering related forces with high accuracy, including resistant force, based on building design standards. This method will be useful for damage assessment in areas that have no experience of tsunamis.

The Sassy Scientist – Managing Monsters

Every week, The Sassy Scientist answers a question on geodynamics, related topics, academic life, the universe or anything in between with a healthy dose of sarcasm. Do you have a question for The Sassy Scientist? Submit your question here. Aminta asks: How do you deal with bad co-authors (i.e. people who make writing papers more complicated and unpleasant than it needs to be) that are also senior scientists? Dear Aminta, Annoy them as much as possible. Relentlessly, but politely. Haunt …


Investigating the climate history of Central Asia in Kashmir/India

As in most arid areas, dust storms are quite common in India. Repeatedly, the wind carries large quantities of dust from the Thar Desert in the south-west into the Asian country, sometimes across long distances. There have also been dust storms in India in the past, making geoarchives of aeolian dust a suitable recorder of the past local climate- and dust history. When the climate was rather warm and humid, thick soils would form in the dust deposits. However, if …

Adaption

As temperature records have continuously been broken all over the world, many of us scientist had to endure extreme conditions in our overheated offices to still get work done. Climate change is happening, and faster then we’d like to think, but how does this play a role in the scientific community? In this week’s blog post, geodynamicist Nicolas Coltice (professor at Ecole Normale Superieure de Paris) shares his passionate opinion on the matter and sheds light on several important topics …
