The impact of the man-made climate crisis on Antaretica is scientifically undeniable：stable ice shelves are retreating，air temperature increased by 3 degrees Celsius，krill（磷蝦）numbers are declining，melting ice is contributing to sea level rise，and polar bears and seals are getting displaced."Antaretic biodiversity could decline substantially by the end of the century if we continue with business as usual."Jasmine Rachael Lee，lead author of the University of Queensland study says.
   Published in the journal PLOS Biology，the study finds population declines are likely for 65%of the continent's plants and wildlife by the year 2100.The most vulnerable（脆弱的）species is the Emperor penguins.In October 2022，the U.S.Fish and Wildlife Service listed Emperor penguins as a threatened species under the Endangered Species Act（ESA），as experts predict the flightless seabird will see a 26%to 47%dip in its population by 2050."This listing reflects the growing extinction crisis and highlights the importance of the ESA and efforts to conserve species before population declines become irreversible（不可逆轉(zhuǎn)）."said Service Director Martha Williams at the time.
    Aside from Emperor penguins，other Antarctic specialists，like the Adélic penguin and dry soil nematodes，were also highly vulnerable.We urgently need a combination of global and local conservation action to best conserve Antarctic species.Global action and global voices to help relieve climate change—because the biggest threat to Antaretica is coming from outside of it.And then we need local actions to help protect biodiversity against local threats and give them the best chance of adapting to climate changes.This will help to save our iconic （代表性的） species like the Emperor penguins and all of Antaretical's unique and highly adapted inhabitants.It will also help humankind，as we rely heavily on the priceless services the Antarctic provides in regulating our climate and capturing sea level in its ice sheets.
