These pages will examine this question: Where is the tipping point for unacceptable--or catastrophic--climate change? How close is it, or have we passed it? Are we now endangering human civilization, or the human species? If so, all our priorities need re-thinking. On these pages I will consider all my sources in assessing the current state of the climate challenge, and am investigating responses.
Checking in from New York City-- I'm here for the People's Climate March. Tomorrow there are workshops and sessions all over the place. Sunday, we march!
