Pacific walruses have come ashore on the northwest coast of Alaska. The event has become an annual sign of the effects of climate change.
 
"There appears to be several thousand animals up there," said Andrea Medeiros. She is spokeswoman for the U.S. Fish and Wildlife Service. It is in Anchorage.
 
Images of the walruses were captured by a photographer not connected with the agency near Point Lay. It is an Inupiat Eskimo village 700 miles northwest of Anchorage and 300 miles southwest of Barrow.
 
Walruses have been coming to shore on the U.S. side of the Chukchi Sea in large numbers for about eight years. They also come to shore on the Russian side.
 
Researchers say it's likely a result of less sea ice brought on by climate warming.
 
Walruses dive to feed on clams, sea snails and other food on the ocean bottom. But they cannot swim indefinitely.
 
Many male walruses never leave the Bering Sea. But females, especially mothers with pups, ride the edge of the sea ice as it moves north in summer. The ice moves through the Bering Strait and into the Arctic Ocean. They use sea ice as a platform. From the ice, they dive for food. Their pups rest on the ice.
 
In recent years, sea ice has receded north beyond shallow continental shelf waters. The ice covers water that exceeds 2 miles deep. It is beyond the diving range of an adult walrus.
 
Walruses in large numbers were first spotted on the U.S. side of the Chukchi Sea in 2007. They returned in 2009. In 2011, scientists estimated 30,000 walruses along 1 kilometer of beach near Point Lay.
 
Last year, an estimated 35,000 walruses were photographed. They were 5 miles north of Point Lay.
 
The agency and two others have issued an appeal to stay away from large gatherings of walruses that come ashore. Young animals are vulnerable to stampedes. They can occur when a group gathers nearly shoulder-to-shoulder on a beach.
 
Stampedes can be triggered by a polar bear, human or low-flying airplane.
 
With this year's low summer sea ice, it's not surprising to see walruses on shore looking for a place to rest. That is according to Margaret Williams of the World Wildlife Fund in Anchorage. The sharp decline of Arctic sea ice over the last decade is leading to major changes for wildlife and communities.
 
"Such extreme events are a stark reminder of the urgent need to ratchet down the emissions that are warming our planet," Williams said.

    there are a lot of walruses on shore now.

    I thought this article was interesting, and I liked learning about the walruses. I thought it was interesting because I learned new things about walruses I never knew. I'm also curious what will happen after time progresses, what will happen to the walruses, and if anything new will happen.

    Walruses leave the water and come to the shore or climb on ice for two reasons. Female walruses with pups us the ice as a platform for their pups to rest and a diving area for food.

    Walruses leave the water and come to shore or climb on ice because they are looking for a place to rest.

    I think that this is bad because the walruses might be one of the effect of global warming because the global warming heats up the whole world which also melts the ice chunks that are used for walruses to rest on. The global warming might be the main problem for the walruses because they are starting to move to Alaska because Alaska still has big chunks of ice floating out on the ocean.

    I think that it is depressing for walruses to be forced onto ashore. I believe that people need to do something about the climate changes or animals such as walruses may one day be extinct. I hope that the walruses will have a better life since it is not right for them to be forces ashore.

    Very nice facts about Walruses.

    I think that this is bad news because this means that it is getting warmer and warmer which means that global warming is coming soon. They should really try to help save these walruses because right now there homes are starting to melt. I hope that God will help us soon to stop Global Warming.

    Critical thinking challenge:Why do walruses leave the water and come to shore or climb on ice?

    Walruses leave the water and come to the shore for one important reason. The reason is that the walruses are exposed to a really cold conditions in Antarctica and Arctic with ice available. During global warming the ice melts and the walruses really require ice to survive.So they come to the shoreline where ice is available and they rest there. This is the main reason of why they come to the shore.

    I like how the lead says exactly what is going on, where it is and why. I think they could've elaborated some on how there may be an issue or if it is just interesting that more and more walruses are coming to shore. There was a lot of historical information given and not much of the present circumstance which I think should've been the basis of the article.
