Scientists say that 350 parts per million CO2 in the atmosphere is the safe limit for humanity. We are at 385 ppm and climbing.

350.org is an organization founded by writer/activist Bill McKibben dedicated to raise awareness about climate change.  The site went live in July and is driving toward The Day of Global Climate Action on October 24th.

Veteran photographer Chris Noble put out a call for photographers to support this cause. After meeting Chris a few weeks ago he selected a few of my relevant images for use on their website and possibly as part of an exhibition of large format prints at the L.A. Music Center and the Dorothy Chandler Pavilion in Los Angeles on the Day of Action October 24th. The Producers Guild of America (PGA) is behind the LA event.

Here is the purpose in 350′s own words:

Our mission is to inspire the world to rise to the challenge of the climate crisis—to create a new sense of urgency and of possibility for our planet.

Our focus is on the number 350–as in parts per million, the level scientists have identified as the safe upper limit for CO2 in our atmosphere. But 350 is more than a number–it’s a symbol of where we need to head as a planet.

In order to unite the public, media, and our political leaders behind the 350 goal, we’re harnessing the power of the internet to coordinate a planetary day of action on October 24, 2009.  We hope to have actions at hundreds of iconic places around the world – from the Taj Mahal to the Great Barrier Reef to your community – and clear message to world leaders: the solutions to climate change must be equitable, they must be grounded in science, and they must meet the scale of the crisis.

If an international grassroots movement holds our leaders accountable to the latest climate science, we can start the global transformation we so desperately need.
