At least in our area of the country, consumers are already being assaulted — well before Halloween — with Christmas music, decorations and holiday-themed goods. Reporters are smack in the throes of their own early seasonal blitz: News items carrying a climate or global-warming theme. And I don’t expect the crush of climate news and seminars to diminish until around Christmas.
