On Saturday, Nov. 1, a trio of Medford community groups are hosting a "global warming cafe," described as "a community gathering to share what global warming means to each of us. By exchanging views, feelings and ideas, we will begin personal action to stop global warming and learn to make better choices about our own energy use."

Snacking begins at 4:30, and the "free, really interactive event" is from 5-7 at the West Medford Community Center
111 Arlington St. "We especially want to bring in people who haven't taken action to lower their energy use this winter," said an organizer, Susan Altman. To RSVP, call 781-483-3042 or send e-mail.

I may be in New Hampshire stumping for Obama, but otherwise, I'm looking forward to it.

Meanwhile, tonight is a Boston Green Drinks night: from 6:30 onward at the Other Side Cafe, 407 Newbury St., within site of the entrance of the Hynes stop on the Green Line. If you're reading this, you're invited. No charge, of course, though drinks are on you. Just your drinks.
