2. 1. Climate-induced changes : Its effects on plankton food webs from the Baltic Sea

   Author : Claudia Romero-Oliva; Edna Graneli; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate-induced changes; temperature; acidification; marine food web; natural plankton community; spring; summer; Baltic Sea; Marine ecology; Marin ekologi; Akvatisk ekologi; Aquatic Ecology;

   Abstract : The Earth’s climate is determined different processes occurring in the atmosphere, land and ocean.Anthropogenic activities (mainly combustion of fossil fuels) have increased since the 1950’s, andthus the concentration of greenhouse gases that are warming up the planet. READ MORE

4. 2. Impact of Climate Change on Extreme Events: Insights from Asia and Scandinavia

   Author : Dong An; Avdelningen för Teknisk vattenresurslära; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; extreme events; precipitation extremes; droughts; climate variability; ENSO; climate model; climate projection; the Asia-Pacific region; scandinavia;

   Abstract : As climate has warmed significantly over past decades, numerous studies have confirmed a pattern of more frequent and more intense hydro-climate events across the globe, such as floods, heatwaves, and droughts. Analyzing the variability of climate events with reliable historical data records is one of the most direct approaches for understanding its patterns of change. READ MORE

5. 3. Modelling regional climate-vegetation interactions in Europe : A palaeo perspective

   Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. READ MORE

6. 4. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

   Author : Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; Physical Geography; naturgeografi;

   Abstract : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

7. 5. Model analysis of ocean carbon storage and transport across climate states

   Author : Malin Ödalen; Jonas Nycander; Johan Nilsson; Kevin I. C. Oliver; Nathaelle Bouttes-Mauhourat; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Climate; Climate model; Carbon cycle; Paleoclimate; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : The ocean carbon cycle plays a fundamental role in the Earth’s climate system, on decadal to multi-millennial timescales. Of the carbon held in the ocean, the atmosphere, and the terrestrial biosphere combined, more than 90% resides in the ocean. Carbon enters the surface ocean through air-sea gas exchange and from terrestrial sources. READ MORE
