350 This Weekend

What’s magic about 350? That’s the upper limit (in parts per million) of Carbon Dioxide in the atmosphere to keep climate change to a manageable level.

The problem is, we’re already at 390ppm and increasing.

A series of rallies around the world are scheduled for October 24th, including one here in Portland protesting the Columbia River Crossing (Pioneer Courthouse Square at 12:30 on Saturday).

You can get a preview of the issue on KBOO (FM 90.7) at 8am on Thursday on the Voices from the Edge program.
