Scientific topics – for example, an interview with renowned climate researcher Hans-Otto Pörtner and an up-to-the-minute report on the latest information about the extent of the species crisis and, as an absolute highlight, Joachim Budde’s thoroughly researched résumé of what has (and hasn’t) happened in the fields of research and politics in the five years since the publication of the world-famous “Krefeld Study”. One of the most significant current environmental disasters of the summer, the mass die-off of millions of fish in the River Oder as a combined result of excess warmth, toxins and the invasion of a non-indigenous type of algae, was also comprehensively covered. One of the contributions providing background and context was an interview with the Klement Tockner, Director-General of the Frankfurter Senckenberg-Gesellschaft, who is a limnologist by profession.
