“While the legal standards under the ESA [Endangered Species Act] compel me to list the polar bear as threatened, I want to make clear that this listing will not stop global climate change or prevent any sea ice from melting," Interior Secretary Dirk Kempthorne says in a statement.The move requires the government to protect the species and to take measures to help the bears survive, an important consideration and the likely reason for the delay, as this is the first time a species has been listed due to climate change.
"Any real solution requires action by all major economies for it to be effective. That is why I am taking administrative and regulatory action to make certain the ESA isn’t abused to make global warming policies.”
"This is a profound acknowledgment of the threat not only to polar bears but to the entire Arctic ecosystem," said Andrew Wetzler of the Natural Resources Defense Council. "It is going to provide important protection for polar bear populations."
