Versiegende Energievorr te und zunehmender Verbrauch von Ressourcen durch den Menschen auf dem r umlich und inhaltlich begrenzten Planeten Erde - ein schleichender, kaum sp rbarer Prozess: Es gibt keinen unbegrenzten Zufluss von l, Gas, Kohle und Uran. Energie wird knapp und immer teurer. Doch der Verbrauch w chst weiter. Wie lange k nnen die Vorr te noch reichen? Das Autorenteam, ein Geophysiker und ein Physiker, hat die besten Daten ber die noch vorhandenen Rohstoffvorr te und deren Unsicherheiten analysiert und auf verschiedenen Wegen berechnet, wie lange sie noch reichen k nnen. In diesem Buch werden die Ergebnisse vorgestellt und der Verbrauchsentwicklung gegen bergestellt - abh ngig von den globalen gesellschaftlichen Bedingungen, also unser aller Verhalten und Erwartungen. Es geht nicht um Prophezeiungen oder Angstmache. Es geht um existierende Zukunftsm glichkeiten und n chterne, jedoch beeindruckende Information f r Verantwortung Tragende und alle Konsumenten.

Gravity interpretation involves inversion of data into models, but it is more. Gravity interpretation is used in a “holistic” sense going beyond “inversion”. Inversion is like optimization within certain a priori assumptions, i.e., all anticipated models lie in a limited domain of the a priori errors. No source should exist outside the anticipated model volume, but that is never literally true. Interpretation goes beyond by taking “outside” possibilities into account in the widest sense. Any neglected possibility carries the danger of seriously affecting the interpretation. Gravity interpretation pertains to wider questions such as the shape of the Earth, the nature of the continental and oceanic crust, isostasy, forces and stresses, geol- ical structure, nding useful resources, climate change, etc. Interpretation is often used synonymously with modelling and inversion of observations toward models. Interpretation places the inversion results into the wider geological or economic context and into the framework of science and humanity. Models play a central role in science. They are images of phenomena of the physical world, for example, scale images or metaphors, enabling the human mind to describe observations and re- tionships by abstract mathematical means. Models served orientation and survival in a complex, partly invisible physical and social environment.
