Seaweed: an unlikely but promising food solution in nuclear winter?
Florian Ulrich Jehn, Alliance to Feed the Earth in Disasters (ALLFED), Delaware, USA and Justus-Liebig-University, Gießen, Germany, presents at EGU23 Press Conference

A few weeks ago, at the European Geosciences Union General Assembly EGU23, a group of researchers from different disciplines briefed the media about the impact of war on the oceans, sands, and people. Among them, Florian Ulrich Jehn’s presentation stood out for its rather unlikely proposition: that seaweed appeared to be a promising candidate as a resilient food solution in nuclear winter.

Try typing the phrase ‘period in geosciences’ into Google. You’ll get something like ‘divisions of geological time’, and how we divide ancient earth time into eras, periods and epochs. We learn about this in the first year and again in every subsequent year of geological training. We are both geochronologists, so this is a topic we are deeply familiar with. But we are also both women. To us, and e ...[Read More]

Science tells us: more is more, and less is less. As geoscientists, we therefore intuitively conceive paragraphs of text as a lot of information, and a generous selection of colours as strongly eye-catching. But text-filled, rainbow-coloured poster presentations communicate neither effectively nor in an accessible manner. After working for months or even years on a geoscience project, we have a lo ...[Read More]

Changes in Arctic climate variability and extremes may have significant impacts for migratory birds, according to a study presented at EGU23 by Nomikos Skyllas, a PhD student from the University of Groningen. Many species cross continents during their seasonal migration patterns, travelling from as far as Africa and South America to northern regions such as Siberia and the Canadian Arctic. If you’ ...[Read More]
