Answer:
Global warming presents the gravest threat to life on Earth in all of human history. The planet is warming to a degree beyond what many species can handle, altering or eliminating habitat, reducing food sources, causing drought and other species-harming severe weather events, and even directly killing species that simply can’t stand the heat. In fact, scientists predict that if we keep going along our current greenhouse gas emissions trajectory, climate change will cause more than a third of the Earth’s animal and plant species to face extinction by 2050 — and up to 70 percent by the end of the century. Such a catastrophic loss would irreversibly diminish biodiversity, severely disrupt ecosystems, and cause immense hardship for human societies worldwide.
Since the Center was established, our mission has been to help protect species facing extinction, and as the threat of global warming has spread, our focus on the issue has intensified. The list of species we’ve petitioned and litigated to protect specifically from warming’s effects is constantly growing, and since today truly all species are threatened by global warming in one way or another, we’ve made fighting climate change central to our mission.
LIFE IN THE ARCTIC (AND ANTARCTIC)
The first creatures to be dramatically and visibly affected by global warming have been those in the Arctic, where the impacts of rising temperatures have been felt earlier and more intensely than anywhere else. As warmer air melts the vast expanses of sea ice that help define the Far North, all the animals depending on that ice for hunting, resting, reproducing, and other key life activities lose the platform on which their existence depends.
The iconic polar bear, fast losing the sea-ice habitat beneath its feet, has become a broadly recognized symbol of the harm global warming is causing in the fragile Arctic — mainly because of the Center’s multi-year, ongoing campaign to earn meaningful federal protection for the species. We’re also fighting to keep numerous other Arctic species — including the Pacific walrus; bearded, ringed, spotted, and ribbon seals; Cook Inlet beluga whale; and yellow-billed loon — from being snuffed out by climate change.
At the other end of the Earth, around the South Pole, the emperor penguin is also facing enormous threats from global warming, which causes profound changes in the Antarctic ecosystem and hurts penguins in diverse ways, from reducing prey species to causing ice shelves to collapse. Thanks to a petition and lawsuit by the Center, the emperor and nine other penguin species hailing from around the southern hemisphere are on their way to federal protection.
