Polar Bears Go Hungry as Icy Habitat Melts Away

By Stephen Leahy

BROOKLIN, Canada, Nov 17 (IPS) – The iconic animal of the frozen north, the polar bear, is starving to death because climate change is melting the Arctic Ocean sea ice.

Polar bears hunt seals almost exclusively and do so from the sea ice. But in the past five years, summer sea ice coverage has declined by 20 percent due to warming temperatures. Although excellent swimmers, the bears are not very good at catching seals in the water, so changes in the ice are making it difficult for these giant bears to survive — several have recently been found drowned and to have died of starvation.

This week scientists announced new findings that the survival rate of polar bear cubs in Alaska’s Beaufort Sea has plummeted. In the late 1980s, 65 percent of polar bear cubs in the southern Beaufort Sea survived their first year. That has fallen to an average of 43 percent in the past five years, report scientists at the Canadian Wildlife Service and the U.S. Geological Survey (USGS).

“This an extremely ominous finding for polar bears,” said Kassie Siegel of the Centre for Biological Diversity, an environmental non-governmental organisation, based in Joshua Tree, California.

“We’ve observed massive melting of the sea ice in the Arctic in recent years, and they can’t survive without it,” Siegel told IPS.

Binational Crusade to Save Wetlands

TORONTO, Sep 8 (Tierramérica) – With 20,000 hectares of bright green in a sea of sand in the state of Sonora, the Ciénaga de Santa Clara is one of Mexico’s richest coastal ecosystems. Faced with the imminent reopening of a desalinisation plant just across the border in the United States, a binational team is working to protect the vast wetland.

Ongoing drought conditions in the south-western United States has prompted the George W. Bush government to finance the restart of the long unused Yuma Desalting Plant (YDP) in the border state of Arizona in 2007.

“Full operation of the desalting plant would mean the ciénaga will get less water and the water would be much saltier,” said Karl Flessa, professor of geosciences at the University of Arizona in Tucson.

And “that would completely eliminate the wetland,” according to Jaqueline García-Hernández, a scientist at a food and development research centre (Centro de Investigación en Alimentación y Desarrollo) in the Mexican city of Guaymas, Sonora.

The Ciénaga de Santa Clara is home to some 225 species of birds, like the Yuma clapper rail (Rallus longirostris yumanensis) and southwest willow flycatcher (Empidonax traillii extimus), which are rare in the United States.
