Oxfam is currently taking entries for the Canvas for Change exhibition. It all seems like a pretty good idea. Paint a canvas that highlights the effect climate change has on the earth's poverty stricken. 

People all over the world are taking part in this international project and all entries will be exhibited online in Oxfam’s specially created “web gallery” with the possibility that your artwork will be shown at the UN Climate Summit in Poland later this year.
