International study projects up to 80% of emperor penguin colonies to be ‘quasi-extinct’ by 2100
“Up to 80% of emperor penguin colonies are projected to be quasi-extinct by 2100 [population declines of more than 90%] with business-as-usual increases in greenhouse gas emissions,” it found., the research also found that implementing 10 key threat management strategies in parallel – which would cost an estimated US$23m annually – could benefit up to 84% of Antarctic organisms.
“There are multiple threats impacting Antarctic species despite the fact that we think of it as this remote and pristine wilderness,” said the study’s lead author, Dr Jasmine Lee, of the British Antarctic Survey. “The greatest threat is not coming from within.” Dr Aleks Terauds, of the Australian Antarctic Division and a co-author of the study said the research highlighted that “biodiversity is under considerable pressure in Antarctica”.
“Antarctica is very well protected through the Antarctic treaty and through the protocol [on environmental protection],” Terauds said. “But the uniqueness of the continent, its wilderness values and the incredible biodiversity means that we’re still looking for things that we can do to try and ensure that things are impacted as little as possible.”
