The dataset contains processed model output of future simulations of the East Antarctic Ice Sheet using the Ua ice dynamics model (https://github.com/GHilmarG/UaSource). Simulations were run for 200 years comparing the impact of both an intermediate (RCP4.5 emissions scenario) and extreme (RCP8.5 emissions scenario) as well as maintaining the current oceanic regime or switching to one dominated by circumpolar deep water intrusions. A reference run with constant present-day forcing is also included to assess the relative impacts of the various forcing scenarios. This work was primarily funded by the Natural Environment Research Council, grant number NE/R000719/1. James Jordan, Hilmar Gudmundsson and Adrian Jenkins received funding from the European Union''s Horizon 2020 research and innovation program under grant agreement no. 869304, PROTECT.

This dataset contains glacier boundaries from 1975 to 2020 and elevation change data from 2000 to 2020 over the Cordilleras Vilcanota, Vilcabamba, and Urubamba, Peru. Glacier boundary data were analysed in Google Earth Engine from the Landsat archive and quantifies rate of change in ice extent over recent decades. Elevation change data were analysed in Google Earth Engine from the ASTER archive and quantifies change in ice thickness over decadal intervals from 2000 to 2020. Data are available as shapefiles (.shp) and GeoTIFFs (.tif). Summary data are available as CSVs (.csv). This work was funded by NERC SPHERES Doctoral Training Partnership (NE/L002574/1) and NERC Newton Fund (PEGASUS) (NE/S013318/1).

Simulated ice thickness (ice, metres), supraglacial debris thickness (dh, metres) and velocity (velocity, metres per year) for Khumbu Glacier, Nepal, produced using the iSOSIA ice-flow model presented in Rowan et al. (in revision, Journal of Geophysical Research-Earth Surface). The files contained in this collection present the outputs from three experiments: Experiment 1, six files, three simulations showing the effect of change in mean annual air temperature to the present day from 1.5 degC to 3.5 degC relative to the Little Ice Age. Experiment 2, four files, two simulations showing the effect of change in the h0 constant describing the reduction in sub-debris melt with debris thickness. Experiment 3, four files, two simulations, showing the effect of change in mean annual air temperature to the present day from 2.5 degC to 3.5 degC relative to the Little Ice Age where h0 = 1.1 m. Results from the optimal simulation, nine files, one simulation, showing results for simulated ice thickness, supraglacial debris thickness and glacier velocity for the Little Ice Age, 1984 CE and 2015 CE. Funding was provided by the NERC grant NE/P00265X/1. ***** PLEASE BE ADVISED TO USE VERSION 2.0 DATA ***** The VERSION 2.0 data set (see ''Related Data Set Metadata'' link below) differs from that presented here in Version 1.0 in that the h0 values were revised based on a maximum debris thickness of 2.0 m (compared to 4.0 m in Version 1.0) and the simulations of the active glacier extent were not part of Version 1.0.

Simulated ice thickness (ice, metres, 100 m grid spacing) and supraglacial debris thickness (debris, metres, 100 m grid spacing) for Khumbu Glacier, Nepal, produced using the iSOSIA ice-flow model presented in Rowan et al. (2021; Journal of Geophysical Research-Earth Surface). The model domains used for the entire glacier and active glacier simulations (metres above sea level, 100 m grid spacing), and the present-day ice thickness estimate (metres, 30 m grid spacing) used to create the subglacial topography are included. The files contained in this collection present the outputs from three experiments carried out in Rowan et al. (2021; Journal of Geophysical Research-Earth Surface): 1. Simulation with a continuous debris layer, where h0 = 0.23 m and dT = 1.5 degC, showing the effect of change in mean annual air temperature to the present day (2015 CE) from 1.5 degC relative to the Little Ice Age 2. Simulation with a discontinuous debris layer, where h0 = 0.94 m and dT = 1.5 degC 3. Simulation with a discontinuous debris layer of the active glacier, where h0 = 0.94 m and dT = 1.5 degC The subglacial DEMs used for the model domains for the entire glacier and the active glacier, and the present-day (2015 CE) ice thickness estimated by Rowan et al. (2015, EPSL) to create the subglacial topography are also included (3 files).
