Polar bears are already drowning in climate change

Population Size Declines In southern portions of their range, like Hudson Bay, Canada, there is no sea ice during the summer, and the polar bears must live on land until the Bay freezes in the fall, whereupon they can again hunt on the ice. While on land during the summer, these bears eat little or nothing. In just 20 years the ice-free period in Hudson Bay has increased by an average of 20 days, cutting short polar bears’ seal hunting season by nearly three weeks. The ice is freezing later in the fall, but it is the earlier spring ice melt that is especially difficult for the bears. They have a narrower timeframe in which to hunt during the critical season when seal pups are born.
As a result, average bear weight has dropped by 15 percent, causing reproduction rates to decline. The Hudson Bay population is down more than 20 percent. Retreating Sea Ice Platforms The retreat of ice has implications beyond the obvious habitat loss. Remaining ice is farther from shore, making it less accessible. The larger gap of open water between the ice and land also contributes to rougher wave conditions, making the bears’ swim from shore to sea ice more hazardous. In 2004, biologists discovered four drowned polar bears in the Beaufort Sea, and suspect the actual number of drowned bears may have been considerably greater. Never before observed, biologists attributed the drowning to a combination of retreating ice and rougher seas.

Scarcity of Food Exacerbating the problems of the loss of hunting areas, it is expected that the shrinking polar ice cap will also cause a decline in polar bears’ prey — seals. The reduction in ice platforms near productive areas for the fish that the seals eat affects their nutritional status and reproduction rates. Polar bears are going hungry for longer periods of time, resulting in cannibalistic behavior. Although it has long been known polar bears will kill for dominance or kill cubs so they can breed with the female, outright predation for food was previously unobserved by biologists. Polar Bear Status In 2008, the polar bear was listed as a threatened species under the Endangered Species Act primarily because of the decline of its primary habitat: sea ice. The Secretary of Interior listed the polar bear as threatened but restricted the Endangered Species Act’s protections and thus the polar bear’s future is still very much in jeopardy. The polar bear is the proverbial “canary in the coal mine” of the serious threat global warming poses to wildlife species around the world, unless we take immediate and significant action to reduce global warming pollution.
50,000 Endangered Species Condoms to Be Handed Out at Year-end Events
Dec 23rd
TUCSON, Ariz.— The Center for Biological Diversity is distributing 50,000 free Endangered Species Condoms for holiday and New Year’s Eve celebrations around the country. More than 600 volunteer distributors will hand out the condoms at events in all 50 states. The condoms are part of the Center’s 7 Billion and Counting campaign focusing on the effects of rapid human population growth on rare plants and animals. “There are more than 3 billion people on the planet under the age of 25. The choices this generation makes will determine whether our planet and its wildlife and natural resource base are burdened with 8 billion or 15 billion people. The difference between these paths can be measured by how many other species are left to roam alongside us,” said Jerry Karnas, population campaign director with the Center. “Our Endangered Species Condoms are a great way to get a conversation started about how the growing human population is affecting the wild world around us, especially animals already teetering on the edge of extinction.” As part of its full-time population campaign launched in 2009, the Center has given out 450,000 free Endangered Species Condoms, featuring polar bears, panthers and other species threatened by population growth, loss of habitat and consumption of natural resources. This year, the Center is providing condoms to college health centers, nightclub owners, environmental activists, women’s reproductive-health groups and other activists around the United States. The world’s human population has doubled since 1970, reaching 7 billion in October 2011. According to the latest research, it could exceed 9 billion by 2050. In recent weeks, several federal reports have noted the impact that population is having on the natural world. A recent decision to propose Endangered Species Act protection for 66 coral species said that “the common root or driver of most, possibly all” of the threats that corals face — like climate change and changing ocean conditions — is the world’s growing human population. Another report, by the Department of the Interior, raised serious questions about the ability of the Colorado River to meet demands of a growing population in the western United States. “The evidence is mounting, and the solutions are at hand if only we’re just willing to start talking about them,” Karnas said. “Universal access to birth control, a rapid transition to clean energy, robust land-acquisition programs and much smarter growth policies can combine to forge a future for wildlife and a high quality of life for people. There’s no better time to start than in the new year of 2013.” The Center is the only environmental group with a full-time campaign highlighting the connection between unsustainable human population growth and the ongoing extinction crisis for plants and animals around the world. In 2011 the Center released a report on the top 10 U.S. species threatened by population growth. The Center for Biological Diversity is a national, nonprofit conservation organization with more than 450,000 members and online activists dedicated to the protection of endangered species and wild places.
