Addressing climate change though art
I like this organisation. George Monbiot, Mark Lynas, Herbert Giradet are all on the board. They give funding to organisations applying with specific projects addressing climate change. Eg, Trees For Life. http://www.treesforlife.org.uk/groves/ape.html
Here's their website and vision:

Through music and the arts, APE aims to achieve permanent reductions in greenhouse gas emissions to levels that minimise further degradation of ecological systems and human livelihood.
APE recruits internationally known musicians and artists through albums, concerts, art exhibitions and art related projects to raise awareness of climate change and funds for campaigns and disaster relief.
