The big melt: Tipping points in Greenland and Antarctica
Storing ice volumes of more than 65 meters sea-level equivalent, the ice sheets on Greenland and Antarctica are by far the largest potential source of future sea-level rise. Their long-term stability thus determines the fate of our coastal cities and cultural heritage sites. While massive in size, the ice sheets also belong to the most vulnerable parts of the Earth system: feedbacks between ice, atmosphere and ocean give rise to non-linearities in their response to progressing global warming. Once a critical temperature threshold is crossed, this could lead to self-sustained and potentially irreversible ice loss from drainage basins in Greenland and Antarctica. In this lecture, we will review the processes behind these dynamic instabilities, discuss the potential of crossing ice-sheet tipping points in the future, and explore the resulting impacts on sea-level rise and our global climate – not just for this century, but for the next millennia and beyond.

Ransomware is a type of malware that encrypts the files of infected hosts and demands payment, often in a cryptocurrency such as Bitcoin. In this talk, we present a measurement framework that we used to perform a large-scale, two-year, end-to-end measurement of ransomware payments, victims and operators.

Museen digitalisieren ihre Sammlungen, Dokumentationen und die Vermittlung. Das geht auf verschiedenen Ebenen zu schnell, denn eigentlich wird ihre gesellschaftliche Rolle gerade stark hinterfragt. Nicht nur am Umgang mit kolonialen Erwerbungen entzünden sich Debatten. Der Vortrag beschreibt wie die aktuelle Auseinandersetzung um die gesellschaftliche Rolle von Museen auch die Digitalisierung stärker in den Blick nehmen muss.

Estimates suggest that well over 100 bn € is spent on autonomous vehicle research, or what we might call the “Technology Mobility Complex”. Over recent years dozens of high-profile autonomous vehicle projects claim they are tantalisingly close to launch, only for those projected dates to be quietly pushed back. This talk will critically examine the inflated claims of the self-driving car industry and argue that the hyped economic and social benefits are based on unproven and dubious ...
