    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. 22. Petermann Glacier Ice Shelf in a warming world : Insights from 3-D numerical modelling of ice shelf-ocean interactions at Petermann Fjord, Northwest Greenland

    Author : Abhay Prakash; Nina Kirchner; Qiong Zhang; Riko Noormets; Hans Burchard; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland; ice shelf-ocean interactions; numerical ocean modelling; naturgeografi; Physical Geography;

    Abstract : The Greenland Ice Sheet (GrIS) is currently the largest contributor to global mean sea level rise, and contemporary mass loss rates are likely lower bounds for the rates to be observed in decades to come. At present, marine outlet glaciers along the northern GrIS margin, with an ice volume estimated at 400 cm mean global sea level rise equivalent, are still largely buttressed by ice shelves.

  5. 23. Hydrology and Bed Topography of the Greenland Ice Sheet : Last known surroundings

    Author : Katrin Lindbäck; Rickard Pettersson; Francisco Navarro; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland Ice Sheet; radio-echo sounding; digital elevation models; ice thickness; bed topography; spectral analysis; roughness; subglacial hydrology; water piracy; englacial features; drainage catchments; meltwater runoff; ice dynamics; klimatförändringar; Grönlands inlandsis; markbaserad radar; digitala höjdmodeller; istjocklek; bottentopografi; spektralanalys; subglacial hydrologi; englaciala strukturer; avrinningsområden; isdynamik;

    Abstract : The increased temperatures in the Arctic accelerate the loss of land based ice stored in glaciers. The Greenland Ice Sheet is the largest ice mass in the Northern Hemisphere and holds ~10% of all the freshwater on Earth, equivalent to ~7 metres of global sea level rise. READ MORE

  6. 24. Climate-associated human health effects

    Author : Tzu Tung Chen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; malaria; Plasmodium vivax; mortality; historical epidemiology; vector-borne diseases; climate change; Nordic countries;

    Abstract : The intensifying impacts of climate change on human health represent a significant and pressing global health threat of the current century. This encompasses both short and long-term effects on human health, as well as ecosystem changes linked to rapid shifts in climate, and the subsequent spread of vector-borne diseases. READ MORE

  7. 25. Force Budget Analysis of Glacier Flow : Ice Dynamical Studies on Storglaciären, Sweden, and Ice Flow Investigations of Outlet Glaciers in Dronning Maud Land, Antarctica

    Author : Jim Hedfors; Veijo Pohjola; Else Kolstrup; Niels Reeh; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; force budget; ice flux; ice dynamics; mass balance; strain heating; climate change; Storglaciären; Dronning Maud Land; Antarctica; Naturgeografi och sedimentologi; Physical geography; Naturgeografi;

    Abstract : This thesis contributes to the understanding of glacier response to climate change by ice dynamical studies on Storglaciären, Sweden, and Bonnevie-Svendsenbreen, Kibergbreen and Plogbreen in Dronning Maud Land, Antarctica. Ice surface velocities, ice geometry and temperature information is fed through a force budget model to calculate ice mass outflux of these glacial systems via three-dimensional stress distributions for a flux-gate.
