The Anthropocene concept as a wake-up call for reforming democracy

Human activity has reshaped all parts of the Earth system. For this reason, a vast majority of geologists at the 35th International Geological Congress in Cape Town (September 2016) spoke out in favor of changing the classification of geological epochs and of declaring a new world age – the Anthropocene. This chapter points at implications that the proclamation of the Anthropocene should have for the currently relevant concept of democracy. In particular, it is argued that the transition into a new phase of geology also necessitates a further advancement of our form of government. Democracy, as it has been conceived of and practiced until now, has to a large extent ignored the problem of ‘presentism’. This chapter suggests an extension of the 300-years-old separation of powers between the legislative, executive and judicial branch. It is argued that in order to make our political system more future-oriented, there is a need for a new (fourth) branch which ensures that the interests of future generations be taken into account within today's decision-making process. A newly-established ‘future council’ should have the right to introduce legislation, integrating the competences of this new institution with those of parliament. The chapter concludes with a discussion about the legitimacy of offices for future generations (OFGs) as the embodiment of the proposed future branch

Tangos: the agile numerical galaxy organization system

We present Tangos, a Python framework and web interface for database-driven analysis of numerical structure formation simulations. To understand the role that such a tool can play, consider constructing a history for the absolute magnitude of each galaxy within a simulation. The magnitudes must first be calculated for all halos at all timesteps and then linked using a merger tree; folding the required information into a final analysis can entail significant effort. Tangos is a generic solution to this information organization problem, aiming to free users from the details of data management. At the querying stage, our example of gathering properties over history is reduced to a few clicks or a simple, single-line Python command. The framework is highly extensible; in particular, users are expected to define their own properties which tangos will write into the database. A variety of parallelization options are available and the raw simulation data can be read using existing libraries such as pynbody or yt. Finally, tangos-based databases and analysis pipelines can easily be shared with collaborators or the broader community to ensure reproducibility. User documentation is provided separately.Comment: Clarified various points and further improved code performance; accepted for publication in ApJS.
