Winter forecast: Sustained blizzard of climate news
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. That’s when the next United Nations COP — or Conference of the Parties — will end this year’s pivotal round of negotiations in Copenhagen aimed at producing a new climate treaty.

Carbon emissions: Trend improves, but …
Sometimes what’s bad for the economy can be good for the planet. Or so argued Lester Brown, president of Earth Policy Institute, yesterday. This environmental trend spotter pointed to several developments that may have escaped our attention as the global economy alternately sputtered and entered periods of freefall throughout the past 18 months. Trend one: U.S. emissions of carbon dioxide, a leading greenhouse gas, have taken a tumble.
