The near-term haze of climate disasters obscures our possible futures. But long-term trends leave room for optimism. This may be my last Cosmic Relief column, at least for now: I’ve accepted the position of Senior Scientist for Astrobiology Strategy at NASA, which sadly will eat up my writing time. Contributing to S&T has been a great gig, and I truly appreciate all the wonderful feedback from readers over the years. I just re-read my first column, from January 2009 (https://is.gd/CRfirst).
