Today we celebrate the remarkable recovery of the brown pelican from the brink of extinction.

The state bird of Louisiana, the brown pelican was nearly wiped out in the state and throughout its ranges along the Gulf Coast, the Atlantic coast and in southern California.

Today, more than 650,000 can be found across Florida, and the Gulf and Pacific coasts, as well as in the Caribbean and Latin America.

Please take a moment to share your views on this landmark conservation victory.

Our National Climate Campaign wants to thank all of our members and activists for their support during this incredibly important vote:

My grandmother grew up in southern Maine and still lives there. She tells the story of going ice skating on local ponds over Thanksgiving holidays when she was a kid.

A couple of years ago, my family spent the Thanksgiving break with her in Maine. The ponds were certainly not frozen over. In fact, temperatures were in the 60s.

One Indian summer Thanksgiving doesn't prove anything. But, with Maine's climate predicted to resemble that of the Mid-Atlantic region in coming decades, will Mainers be able to ice skate over Thanksgiving again?

What about you? Have you noticed climate changes in your backyard? We'd love to read your story.

The Canada lynx, America's second largest cat, was originally listed as endangered because of habitat loss and overtrapping. Now, global warming poses a new threat as this cat's snowy habitat thins. If you've been lucky enough to come across one of these furry hunters, please comment below and share your story!
