Global+Warming

Hey, we decided to do our page on the effects of Global Warming on polar bears. Global warming is a worldwide problem caused by greenhouse gasses like carbon dioxide being released into the atmosphere. This makes it dificult for heat to be released. When this builds up, over time, global temperatures will rise. This will melt the ice polar bears live on. This can cause a dramatic drop in polar bear population.

[|**Two-thirds of Polar Bears Could Perish by 2050**] The U.S. Geological Survey reports that thinning sea ice from global warming could kill off two-thirds of the world's polar bears (including the entire Alaskan population) by mid-century. But the report contains a ray of hope: Many populations of bears could survive if long-term warming trends are reversed.

[|**Tell the Bush Administration to Protect Polar Bears**] Through our legal action, NRDC helped sparked a global outcry over the plight of the polar bear and forced the Bush Administration to propose protecting the bear under the Endangered Species Act. It's a big step forward, but the proposal won't become reality without a huge outpouring of support from concerned Americans like you. Please answer the polar bear's S.O.S by [|sending an Official Citizen Comment to the Bush Administration] right now!
