Polar bears and penguins get all the attention but there's more than large, fuzzy and feathered animals thriving at the frozen antipodes of our planet. Both of Earth's polar environments host rich webs of plants and animals—and all of these inhabitants face a changing clime.
A warming global climate may favor species that don't intimately depend on ice that floats on the sea to hunt or are more versatile in what they can eat as well as those able to thrive in higher temperatures. Although it is inevitable that some flora and fauna will go extinct in the coming years, experts agree that the poles will not become a dead zone. There will still be life, but the residents will be different.
"In a very short amount of time, you're going to drastically rearrange that ecosystem," says Brendan Kelly, a marine biologist at the University of Alaska Southeast in Juneau. "There will be some biological community there, it just won't look like anything like what's been there."

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
