Impact of climate warming on Arctic plant diversity: phylogenetic diversity unravels opposing shrub responses in a warming tundra
(2022-10-13)The Arctic biome is at significant risk, with recent observations suggesting that climate change is warming the Arctic nearly four times faster than the global average. Last decade, evidence from experimental warming ... -
Outdoor heat in urban areas - Model development and applications
(2022-05-10)Heat waves and high outdoor air temperature can lead to heat stress with negative implications for human health and wellbeing such as heat stroke, heat cramps, dehydration and in extreme cases death. The urban population ... -
Impact of climate variability on dynamic groundwater storage in mid- to high latitude countries
(2022-04-07)Climate change will alter the hydrological cycle, potentially changing dynamic groundwater storage and increasing groundwater drought risk. Climate influences groundwater storage directly via changes in groundwater ... -
Nitrogen Losses from a Clay-rich Soil used for Cereal Production in south-western Sweden
(2021-11-24)Addition of fertiliser nitrogen (N) in crop production increases yields and protein contents, but all is not taken up by the crop. Instead, some of the N is lost to air and waters, contributing e.g. to climate change, ... -
Ample Rare Elements: A Geochemical Anomaly in the Earth's Crust at Norra Kärr
(2021-11-18)The Norra Kärr alkaline complex in southern Sweden (58°06’N, 14°34’E) is a classic occurrence of agpaitic rocks, which contains a large mineral deposit of rare-earth elements (REE), Zr, and Nb. The complex consists of ... -
Sedimentology and Geomorphology of Glacial Landforms in Southern Sweden
(2021-02-26)Ice sheets are disintegrating due to global warming. One factor controlling ice-sheet behavior is the processes active beneath the ice sheet. In particular, processes connected to glacial meltwater drainage are essential ... -
Changes in near-surface winds across Sweden over the past decades - Observations and simulations
(2020-11-19)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 ... -
Towards prediction in ungauged aquifers – methods for comparative regional analysis
(2020-05-12)Hydrogeological investigations and in particular groundwater resource assessments are strongly reliant on understanding the factors controlling groundwater level dynamics. However, historical records of measured groundwater ... -
Tropical cyclone induced extreme wind, rainfall, and floods in the Mekong River Basin
(2020-04-27)Increasing magnitude and frequency of climate extremes under global warming are threatening the socioeconomic development in many parts of the world. The Mekong River Basin (MRB) is a good example for how climate extremes ... -
The Nitrogen Cycle in Soil – Climate Impact and Methodological Challenges in Natural Ecosystems
(2018-08-31)Nitrogen (N) is a fundamental element for life, and limiting in many terrestrial ecosystems. In non-N-fertilized ecosystems, the N inputs can be low, and the nutrient availability for plants is determined by the internal ... -
Road climate studies with emphasis on road surface temperature variations and hoar frost risk
(2018-05-24)An effective road transportation system is a key enabler for national and global economic growth. In the wintertime, the presence of snow and ice on road surfaces reduces road surface friction and can result in serious ... -
Nitrous Oxide Production in Agricultural Soil – Linking Biogeochemical Pathways and Drivers
(2018-05-09)Nitrous oxide (N2O) is a long-lasting and potent greenhouse gas responsible for depletion of stratospheric ozone. As the atmospheric N2O concentration reaches all-time highs, emission variability in space and time still ... -
Tree rings and climate in Scandinavia and Southern Patagonia
(2017-11-30)The present knowledge of temperature variability during the past millennium has been greatly improved due to an increasing availability of reconstructions made based on paleoclimate proxies, such as tree-rings. These ... -
Rheological response to tectonic and volcanic deformation in Iceland
(2016-05-06)Iceland is one of the few places in the world where a Mid-Oceanic Ridge (MOR) is exposed on land, and this gives good opportunity to study geodynamic processes. Spreading of Mid-Atlantic Ocean Ridge (MAR) segments in Iceland ... -
Spatiotemporal climate and atmospheric circulation variability in Asia inferred from tree rings
(2016-04-21)Observed 20th century warming trends accompanied by more frequent weather extremes such as droughts or intense rainfall events have consequences for societies and environments alike. In Asia, where the majority of the ... -
Modelling of the daytime and night-time urban thermal environment
(2016-03-11)The world’s urban population is expected to increase over the coming decades. To maintain and improve the health and well-being of urban citizens, it is important to increase our knowledge and develop methods for evaluating ... -
Land use GHG emissions and mitigation options, simulated by CoupModel
(2015-12-09)Climate change and greenhouse gas (GHG) emissions are one of the major challenges to the humankind of 21st Century. This thesis focuses on understanding, estimating and suggesting mitigation of the GHG emissions (mainly ... -
Climate regulation provided by urban greening - examples from a high latitude city
(2015-11-06)Cities exert a strong influence on urban climate, and consequently on human health and wellbeing. This increases the importance of considering climate issues in urban planning, particularly in the context of global climate ... -
Summer Climate Variability during the Past 1200 Years in Central Scandinavia – A Tree-Ring Perspective
(2015-05-22)To set the current 20th century warming in a long-term context, significant efforts have been made to reconstruct hemispheric-to-global temperatures beyond the instrumental period. Tree-rings, which have annual resolution ... -
Energy Efficiency in Winter Road Maintenance - A Road Climatological Perspective
(2015-05-07)Practices in winter road maintenance are dependent on the climate and weather impacting roads and the road users’ requirements. As in many other fields of transportation, it is of interest to investigate fuel efficiency ...
