‘Climate-gate’: Beyond the embarrassment
The United Nations Climate Change meeting, which I arrive at tomorrow in Copenhagen, is currently deadlocked on more important issues than who said what impolitic thing about somebody else in a private email to a colleague.

Large Hadron Collider suffers carb attack
Efforts to get the Large Hadron Collider up and running just encountered a temporary snag, according to yesterday's online edition of The Times of London. A crusty chunk of bread “paralysed a high voltage installation that should have been powering the cooling unit.”

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.

Discovery of Higgs at Large Hadron Collider might not make all physicists happy
Nobel laureate Steven Weinberg suggests many would be horrified if all the LHC discovers is its prime target, the Higgs boson. Tom Siegfried and others blog from the 47th annual New Horizons in Science meeting sponsored by the Council for the Advancement of Science Writing in Austin, Texas.
