2. 1. Comparing Climate Forcers on a Common Scale

   Author : Erik Sterner; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial-temporal Optimization; Carbon Cycle; Greenhouse Gases; Short-lived Climate Forcers; Upwelling-Diffusion; Metric; Energy Balance; Sea Level Rise; Non-cooperative Nash Equilibrium; Resource Extraction;

   Abstract : The climate is changing at a rapid pace. Through the United Nations Framework Convention on Climate Change (UNFCCC), the world has agreed to hold the on-going temperature increase below 2 °C. Climate change is caused by emissions of different atmospheric species (climate forcers). READ MORE

4. 2. On the use of aerosol optical properties and satellite-retrieved trace gases in regional air quality modelling

   Author : Emma Andersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Model; Climate; Radiation; Satellite; Air Quality;

   Abstract : The effects of anthropogenic pollutants in the lower atmosphere (troposphere) have been shown, historically and scientifically, to have a deleterious effect on both plant and animal life. Pollutants such as near-surface ozone and soot (black carbon) are two notorious examples with clear anthropogenic sources. READ MORE

5. 3. Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change

   Author : Juan Camilo Acosta Navarro; Ilona Riipinen; Annica M.L. Ekman; Hans-Christen Hansson; Risto Makkonen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; Air quality; Land use; General circulation; Atmosphere-Ocean interactions; Aerosol climate effects; Earth system modelling; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. READ MORE

6. 4. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models

   Author : Thanh Le; MERGE: ModElling the Regional and Global Earth system; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar forcing; volcanic forcing; greenhouse gases radiative forcing; Granger causality; near-surface air temperature; ENSO; IOD; CMIP5; North Atlantic;

   Abstract : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. READ MORE

7. 5. Surface energy exchange and land-atmosphere interactions of Arctic and subarctic tundra ecosystems under climate change

   Author : Christian Stiegler; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface energy exchange; Arctic and subarctic tundra; climate change; permafrost; eddy covariance; snow cover; micrometeorology;

   Abstract : The surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. READ MORE
