The Copenhagen climate talks closed with the sinking hopes of many enviro-groups who called the summit a failure — and with a “sinking” mural by world-renowned graffiti artist Banksy.

“I don’t believe in global warming,” reads Banksy’s new mural — with the bottoms of the letters painted below the water, as if sinking in disbelief. That message is one of four new Banksy works painted on the Regent’s Canal in Camden, north London, according to the BBC. (via Social Vibe)

Feeling disillusioned about the talks? Cheer up by reading fellow MNN blogger Karl Burkhart’s post, “The bright side of ‘Flopenhagen,” then make a resolution to be even more eco-active in 2010 — before all of Banksy’s letters really sink under water.
