1. 1. Climate, Conflict and Coping Capacity : The Impact of Climate Variability on Organized Violence

   Författare :Nina von Uexkull; Erik Melander; Hanne Fjelde; Jack A. Goldstone; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; civil conflict; communal conflict; climate change; climate variability; Sub-Saharan Africa; Kenya; geo-referenced event data; agricultural dependence; vulnerability; Peace and Conflict Research; Freds- och konfliktforskning;

   Sammanfattning : Understanding the conflict potential of climate variability is critical for assessing and dealing with the societal implications of climate change. Yet, it remains poorly understood under what circumstances – and how – extreme weather events and variation in precipitation patterns affect organized violence. LÄS MER

3. 2. Studies of Volcanic Influence on Aerosols, Clouds and Climate

   Författare :Johan Friberg; Ergonomi och aerosolteknologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lowermost stratosphere; volcanic aerosol; upper troposphere; sulfurous aerosol; carbonaceous aerosol; ion beam analysis; volcanism; indirect effect; radiative forcing; direct effect; Stratosphere; Fysicumarkivet A:2016:Friberg;

   Sammanfattning : This thesis focuses on the influence of volcanism on the compositions of the aerosols in the upper troposphere (UT) and lowermost stratosphere (LMS), and their direct and indirect impact on climate. Aerosol data were obtained by aircraft-borne sampling, using the CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) platform, and laboratory-based ion beam analysis of aerosol samples at the Lund Ion Beam Analysis Facility (LIBAF).

4. 3. Paleoclimate perspective on Earth's climate sensitivity and feedbacks

   Författare :Martin Renoult; Thorsten Mauritsen; Navjit Sagoo; Masa Kageyama; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleoclimate; Climate sensitivity; Climate feedbacks; Last Glacial Maximum; Pliocene; Snowball Earth; Emergent constraint; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

   Sammanfattning : The addition of carbon dioxide (CO2) in the atmosphere due to human activities is the main driver of global warming. How much the Earth will warm in the future is often represented by the Earth's equilibrium climate sensitivity (ECS), the long-term temperature response considering the effect of climate feedbacks after an abrupt and sustained doubling of atmospheric CO2 from pre-industrial concentration.

5. 4. Climate Change: Models, Metrics and Meaning Making

   Författare :Erik Sterner; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate Science Literacy; Emission Metrics; Knowledge-Behavior Gap; Short-lived Climate Forcers; SF Failure; Integral Theory; Carbon Cycle; Sea Level Rise; Common Pool Resources; Resource Extraction;

   Sammanfattning : This thesis, combining research in climate science and educational science, investigates different aspects of climate knowledge. It consists of five papers and covers three major topics: emission metrics, public understanding of atmospheric CO2 accumulation, and spatial modelling of natural resource use. LÄS MER

7. 5. From Sea to Society - Climate Change, Microbial Community Interactions and Assessing Climate Risk on Society

   Författare :Gurpreet Kaur-Kahlon; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton; Bacteria; Climate change; Quorum sensing; Microbial blooms; Vulnerability factors; Arabian Sea; Southwest India;

   Sammanfattning : Unicellular organisms, microalgae and bacteria, less than one millimeter in size make the world go round. Phytoplankton and cyanobacteria, for example, plays an inevitable role contributing 50-85% to the world’s oxygen via photosynthesis. LÄS MER
