TWO types of ice seals joined polar bears on the list of species threatened by the loss of sea ice, which scientists say reached record low levels this year due to climate warming.
Ringed seals, the main prey of polar bears, and bearded seals in the Arctic Ocean will be listed as threatened under the Endangered Species Act, the US National Oceanic and Atmospheric Administration announced.
A species is threatened if it's likely to become endangered within the foreseeable future throughout a significant portion of its range.
The listing of the seals came after federal scientists did an extensive review of scientific and commercial data. It has no effect on subsistence hunting by indigenous people.
"They concluded that a significant decrease in sea ice is probable later this century, and that these changes will likely cause these seal populations to decline," said Jon Kurland, protected resources director for NOAA Fisheries' Alaska region.
Alaska Governor Sean Parnell late on Friday called the science behind the decision speculative and said the state will consider legal action. The state unsuccessfully challenged the polar bear listing.
Millions of ringed seals and hundreds of thousands of bearded seals can be found, Parnell said in a prepared statement.
"The ESA was not enacted to protect healthy animal populations," Parnell said. "Despite this fact, the NMFS continues the federal government's misguided policy to list healthy species based mostly on speculated impacts from future climate change, adding additional regulatory burdens and costs upon the State of Alaska and its communities."
Ringed seals are the only seals that thrive in completely ice-covered Arctic waters. They use stout claws to dig and maintain breathing holes.
When snow covers those holes, females make snow caves, where they give birth to pups that cannot survive in ice-cold water.
