Gary Braasch is an environmental photographer who for 25 years has reported on natural history in many parts of the world. Since 1999, he has been working on a project titled "World View of Global Warming" in which he photographs areas on all continents that illustrate documented results of climate change and repeats historic photographs to show the changes. He works with environmental groups, scientists and editors to educate the public, urging government and corporate sectors to more directly address the reality of climate change.

Magnum Photos is a photographic co-operative of great diversity and distinction owned by its photographer-members. They recently produced a beautiful and disturbing photo essay about climate change, titled "One Planet, One Chance."
