Climate change drives expansion of Antarctic ice-free habitat
Antarctic terrestrial biodiversity occurs almost exclusively in ice-free areas that cover less than 1% of the continent. Climate change will alter the extent and configuration of ice-free areas, yet the distribution and severity of these effects remain unclear. Here we quantify the impact of twenty-...

Antarctic terrestrial biodiversity occurs almost exclusively in ice-free areas that cover less than 1% of the continent.
