New data from the National Snow and Ice Data Center (NSIDC) reveals that Antarctic sea ice is growing at its lowest rate in recorded history, with the continent missing an Argentina-sized amount of sea ice.
Because climate change is melting Antarctic sea ice at an unprecedented rate, scientists have mostly focused on the problems caused by the infusion of so much water into the ocean — problems like rising sea levels and collapsing ocean currents. Yet glaciologists who study Antarctica are warning of a red flag that few predicted, a development so freakish that if not for climate change, experts believe it would not happen except every few million years.
