Climate action heavyweight Bill McKibben of 350.org will be speaking here in Nevada County - venue and date being Miner's Foundry and April 17, I'm pretty sure.
Kudos to those who had the vision to invite him.
Also - if you haven't already watched this - here's a ~30 second NASA animation of earth's recorded temperatures from 1884-2011 (human actions are driving it, not the sun) ...
Also, projected future increases (at link, scroll down; note & consider the divergent red & blue paths) show the need for meaningful action ASAP.
