Deglacial to Holocene variability in surface water characteristics and major floods in the Beaufort Sea
(Communications Earth & Environment, 2020-10-09)Surface water characteristics of the Beaufort Sea have global climate implications during the last deglaciation and the Holocene, as (1) sea ice is a critical component of the climate system and (2) Laurentide Ice Sheet ... -
Elastic deformation plays a non-negligible role in Greenland’s outlet glacier flow
(Communications Earth & Environment, 2021-11-09)Future projections of global mean sea level change are uncertain, partly because of our limited understanding of the dynamics of Greenland’s outlet glaciers. Here we study Nioghalvfjerdsbræ, an outlet glacier of the Northeast ... -
Exploration of an ice-cliff grounding zone in Antarctica reveals frozen-on meltwater and high productivity
(Communications Earth & Environment, 2021-05-25)Ice fluxes across the grounding zone affect global ice-sheet mass loss and sea level rise. Although recent changes in ice fluxes are well constrained by remote sensing, future projections remain uncertain, because key ... -
High geothermal heat flow beneath Thwaites Glacier in West Antarctica inferred from aeromagnetic data
(Communications Earth & Environment, 2021-08-18)Geothermal heat flow in the polar regions plays a crucial role in understanding ice-sheet dynamics and predictions of sea level rise. Continental-scale indirect estimates often have a low spatial resolution and yield largest ... -
Return to rapid ice loss in Greenland and record loss in 2019 detected by the GRACE-FO satellites
(Communications Earth & Environment, 2020-08-20)Between 2003-2016, the Greenland ice sheet (GrIS) was one of the largest contributors to sea level rise, as it lost about 255 Gt of ice per year. This mass loss slowed in 2017 and 2018 to about 100 Gt yr−1. Here ... -
Snowfall-albedo feedbacks could have led to deglaciation of snowball Earth starting from mid-latitudes
(Communications Earth & Environment, 2021-05-14)Simple and complex climate models suggest a hard snowball – a completely ice-covered planet – is one of the steady-states of Earth’s climate. However, a seemingly insurmountable challenge to the hard-snowball hypothesis ...
