Greenhouse gas emissions threaten survival of emperor penguins - ecologist

RNZ 07 Aug 2021
Emperor penguins will become effectively extinct by 2100 if Antarctic sea ice continues to decline at current rates due to global warming, a new report predicts. Australian Antarctic Division seabird ecologist Barbara Wienecke, who co-authored the paper that appears in the journal Global Change Biology, said the finding was "absolutely devastating".
