The climate crisis requires that we drastically reduce carbon dioxide emissions across all sectors of society. The Story of CO2 contributes to this vital conversation by highlighting the cutting-edge science and emerging technologies – a number of which are already commercially available – that can transform carbon dioxide into a myriad of products such as feedstock chemicals, polymers, pharmaceuticals, and fuels. This approach allows us to reconsider CO2 as a resource, and to add "carbon capture and use" to our other tools in the fight against catastrophic climate change. The Story of CO2 explores all aspects of carbon dioxide, from the atomic to the universal perspective, and takes the reader on an epic journey into our physical world, starting from the moment of the Big Bang, all the way to the present world in which atmospheric CO2 concentrations continue to grow. This story seeks to inspire readers with the latest carbon utilization technologies and explain how they fit within the broader context of carbon mitigation strategies in the shift towards a sustainable energy economy.

This open access book provides a multi-perspective approach to the caravan trade in the Sahara during the 19th century. Based on travelogues from European travelers, recently found Arab sources, historical maps and results from several expeditions, the book gives an overview of the historical periods of the caravan trade as well as detailed information about the infrastructure which was necessary to establish those trade networks. Included are a variety of unique historical and recent maps as well as remote sensing images of the important trade routes and the corresponding historic oases. To give a deeper understanding of how those trading networks work, aspects such as culturally influenced concepts of spatial orientation are discussed. The book aims to be a useful reference for the caravan trade in the Sahara, that can be recommended both to students and to specialists and researchers in the field of Geography, History and African Studies.

Influential German sociologist Franz Oppenheimer invigorated the intellectual discourse of the early twentieth century with the controversial ideas he sets forth in his masterwork, The State. In it, Oppenheimer rejects the centuries-old notion of the social contract espoused by political philosophers such as John Locke. Instead, he posits that the state is a tool of oppression via which the ruling classes exert their power over less fortunate groups.
