350 parts per million of carbon dioxide is the number the earth needs (that we need, actually) to achieve climate stability. That number is the agreed-upon target of the vast majority of scientists across the globe. Right now, there are 387 ppm in our atmosphere, and that number is climbing.

350.org has created a great video that shows the importance of creating climate stability, and all without words. Today, in the midst of a unseasonable heat wave and record temperatures in Portland, Oregon, I've posted the video for your viewing pleasure. Head on over to 350.org for more, or to join the campaign.
