1. From Sea to Society - Climate Change, Microbial Community Interactions and Assessing Climate Risk on Society
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
2. National Appropriateness of International Climate Policy Frameworks in India, Brazil, and South Africa
Sammanfattning : How does the international climate policy frameworks influence the domestic institutional responses to climate mitigation in emerging economies? And how, in turn, do domestic institutions and politics in emerging economies influence the fate of international climate policy frameworks? The thesis provides answers to these questions by studying domestic engagements with Nationally Appropriate Mitigation Actions in three emerging economies – India, Brazil, and South Africa. The thesis specifically studies how these engagements were influenced by the domestic institutional context provided by national climate policy, norms, and institutional capacity in the three countries.

3. Factors regulating the origin and magnitude of carbon dioxide emissions from high-latitude lakes
Sammanfattning : Lake ecosystems receive, transmit and process terrestrial carbon and thereby link terrestrial, aquatic and global carbon cycles. Most lakes evade CO2 to the atmosphere, but the annual magnitude of CO2 evasion, as well as sources and mechanisms underpinning CO2 evasion from lakes are still largely unresolved. LÄS MER
4. On the Arctic Seasonal Cycle
Sammanfattning : The seasonal cycle of snow and sea ice is a fundamental feature of the Arctic climate system. In the Northern Hemisphere, about 55 million km2 of sea ice and snow undergo complete melt and freeze processes every year. LÄS MER
5. Changes in near-surface winds across Sweden over the past decades - Observations and simulations
Sammanfattning : Driven by a combination of anthropogenic activities and climate changes, near- surface terrestrial winds displayed a large decrease in their magnitude in the past decades, named “stilling”, and a recent recovery in their slowdown. Understanding how wind has changed and identifying the factors behind the observed variabilities is crucial so that reasonable future wind scenarios can be constructed. LÄS MER
