Photographs exhibiting evidence of global warming

I had heard about The Canary Project somewhere before, but the post on Boing Boing led me over to the site.  What they are trying to accomplish should give you a reason to pause and think it over a little.

The mission of The Canary Project is to photograph landscapes around the world that are exhibiting dramatic transformation due to global warming and to use these photographs to persuade as many people as possible that global warming is already underway and of immediate concern.

To compile a persuasive body of images, we will be photographing at least 16 landscapes throughout the world. These images will show that global warming: (1) is affecting the world in a variety of ways (melting, sea-level rise, drought, extreme weather events, dying habitats, etc.); (2) is affecting every place on earth.  [canary-project]
