    Abstract : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.

  4. 2. Radar Measurements of Temporal Variation in a Boreal Forest

    Author : Albert Monteith; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; remote sensing; temporal variation; tomography; antenna array; temporal coherence; Synthetic aperture radar SAR ;

    Abstract : Synthetic aperture radar (SAR) on a satellite platform is a suitable technique for all-weather global monitoring of forest parameters such as biomass. This is important for increasing the accuracy of the global terrestrial carbon flux, the largest uncertainty in our current understanding of the Earth’s carbon cycle. READ MORE

  5. 3. On the intra-seasonal to decadal climate variability over South-Asia

    Author : Faisal Saeed Syed; Heiner Körnich; Erik Kjellström; Jagadish Shukla; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; South Asia; monsoon; western disturbances; fog; climate variability; climate dynamics; teleconnections; ENSO; NAO; CGT; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : South Asia, a land of contrasting landscapes, seasons and climates, is highly vulnerable to climate variability over intra-seasonal to decadal time scales. In winter, precipitation over the western parts of south Asia and fog over the Indo-Gangetic (IG) plains are the two major climatic features. READ MORE

  6. 4. Seasonal variation of road runoff in cold climate

    Author : Camilla Westerlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : The main objective of this thesis was to characterize and study the behaviour and transport of pollutants, i.e., suspended solids, particles and heavy metals, in road runoff from a small urban catchment during snowmelt and rainfall. READ MORE

  7. 5. Microbial Communities in Boreal Peatlands : Responses to Climate Change and Atmospheric Nitrogen and Sulfur Depositions

    Author : Magalí Martí Genero; Bo Svensson; Åsa Danielsson; Torben Christensen; Linköpings universitet; []

    Abstract : Myrmarker har en stor roll i regleringen av den globala kolbalansen och koncentrationerna av koldioxid och metan i atmosfären, vilket gör dem till speciellt viktiga ekosystem ur ett klimatförandringsperspektiv. Förändringar av myrmarker genom naturlig utveckling eller antropogen påverkan kan därför få långtgående störningar av myrars klimatreglerande funktion. READ MORE
