  1. 6. Attitude control using ion thrusters for solar sailing from Low Earth Orbit to sub-L1

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Celeste Holm; Ida Ygland; [2022]
    Keywords : the sunshade project; geoengineering; solar sailing; attitude control; ion thrusters;

    Abstract : The purpose of the study is to evaluate the possibility of using gridded ion thrusters as a means of attitude control for a solar sail as a part of the sunshade project, which aims to place 10^8 solar sail sunshade spacecraft, each with an area of about 10 000 m^2, at the Sun-Earth Lagrangian point L1 in order to reduce Earth's global temperature. Two types of solar sail sunshade spacecraft were studied. READ MORE

  3. 7. Quantifying changes in soil bioporosity in subarctic soils after earthworm invasions

    University essay from

    Author : Joel Fransson Forsberg; [2021]
    Keywords : Biopores; macropores; geoengineering earthworms; X-ray tomography;

    Abstract : Pores provide important hotspots for chemical and biological processes in soils. Earthworm burrows affect the macropore structure and their actions may create new preferential pathways for water and gas flow within soils. This, in turn, indirectly affect plants, nutrient cycling, hydraulic conductivity, gas exchange, and soil organisms. READ MORE

  4. 8. Feasibility study of the implementation of a space sunshade near the first Lagrangian point

    University essay from KTH/Rymdteknik

    Author : María García de Herreros Miciano; [2020]
    Keywords : ;

    Abstract : The lack of strong measures to avoid the possible fatal consequences of global warming is pushing researchers to look for other alternatives such as geoengineering.Within geoengineering, this study focuses on the space based solar radiation management methods. READ MORE

  5. 9. Of washing machines, plumbing work and thermostats : An analysis of articles on climate engineering in German newspapers

    University essay from Lunds universitet/Humanekologi

    Author : Lea Scheffler; [2019]
    Keywords : climate engineering; geoengineering; critical discourse analysis; newspaper analysis; climate change; technofix; human ecology; Earth and Environmental Sciences; Social Sciences;

    Abstract : This thesis aimed to identify what arguments are made and who is dominating the discourse about climate engineering in German newspapers. Climate engineering refers to methods that deliberately change the environment as a means to combat climate change. READ MORE

  6. 10. Climate engineering in the new media landscape: Culture, Power and Climate Control

    University essay from Lunds universitet/Humanekologi

    Author : Holly Buck; [2011]
    Keywords : geoengineering; climate engineering; discourse analysis; narratives; catastrophism; securitization of climate change; media content analysis; Social Sciences;

    Abstract : Climate engineering, or geoengineering, is large-scale technological intervention in the global climate system. How is this understood within our culture, what power relations are implied in the idea, and what are geoengineering's implications for sustainability? This thesis begins to examine this topic through the lens of culture by presenting a media analysis. READ MORE
