Day 350: International Day of Climate Action
In 2008, NASA climatologist James Hansen and his team produced a landmark series of studies that showed that if we let the amount of carbon in the atmosphere top 350 parts per million, we can’t have a planet “similar to the one on which civilization developed and to which life on earth is adapted.” We’re currently at 390 parts per million. On October 24, people in more than 1000 communities around the globe will take action to make the number 350 visible to everyone.

Denver Green Drinks
Every month people who work in the environmental field meet up for a beer at informal sessions known as Green Drinks. There’s a lively mixture of people and always a different crowd making Green Drinks an organic, self-organizing network. These events are very simple and unstructured, but many people have found employment, made friends, developed new ideas, done deals and had moments of serendipity.
