Inspiring the world to 350

As the summer heat starts to build across Italy, people are thinking about climate change. I've just come from a festival of one-act plays about global warming called 'Climate of Concern' that featured the work of some of the finest writers on the planet. The novelist Don DeLillo, for instance,who contributed a very funny and very moving drama about a man journeying for advice to a guru who has little left to give.

The growing involvement of the arts in this fight is one of the best pieces of news we have. Since science has largely done its job and given us both a powerful warning and now a definitive number to work with, it's up to the rest of us to do our part. We need many more musicians and artists who will take 350 and make it real for people.

Be sure to check out and get involved with two of our exciting artistic Global Projects - the Postcard Project, and the Craft Challenge, a collaboration between 350.org and Craftster.org.
