Feds propose banning giant snakes
Today, the U.S. Fish & Wildlife Service announced plans to ban the importation and interstate transport of nine species of giant snakes. It’s a good idea, but a little like closing the barn door after the horse — or in this case, the pythons and anacondas — got loose.

BPA is regulated . . . sort of
Food and Drug Administration officials “say they are powerless to regulate BPA” because of a quirk in their rules, according to a story that ran Sunday in the Milwaukee Journal Sentinel. It comes from a reporter who has made an award-winning habit of documenting the politics that have helped make the hormone-mimicking bisphenol-A a chemical of choice for many manufacturers.

IPCC relied on unvetted Himalaya melt figure
British newspapers have uncovered what appears to be an embarrassing fact-checking omission by the Intergovernmental Panel on Climate Change, or IPCC. It regards the degree of glacial melting in the Himalayas — information that said parts of the area could be icefree a quarter century from now.

BPA and babies: Feds acknowledge concerns
Federal health and research officials outlined new guidance today for parents on the use of plastics made from bisphenol-A, a hard, clear plastic. Their bottom line: Minimize BPA-based products that could make contact with foods or drinks that infants or toddlers might consume — especially hot foods and drinks. But the Food and Drug Administration stopped short of recommending that parents pitch baby bottles and sippy cups made from BPA. Nor did it call for parents to avoid processed infant formulas and baby foods — some of which it acknowledges are contaminated with traces of BPA.

Vast majority of teens are sleep-deprived
Most adolescents need at least eight hours of zzzzz’s a night, studies show, and ideally should garner at least nine. A new study tells us just how many kids meet their slumber quota: a whopping 7.6 percent.

Pet tarantulas can pose a hairy threat
A new medical case report reaffirms why even largely non-venomous tarantulas can make questionable pets. Some respond to stress by expelling a cloud of barbed hairs that can lodge in especially vulnerable tissues. Like your eyeball.

Climate deal reached, importance debated
“Finally, we sealed the deal. And it is a real deal,” said United Nations Secretary General Ban ki-Moon this morning at an 11:15 press briefing. He was referring to a new climate accord – one aimed at reducing global greenhouse-gas emissions and setting up a green trust fund for mitigation and adaptation programs in the world’s poorest countries, ones that are already being hammered by a changing climate.

Climate: Deal or no deal?
We’ve got a climate accord, President Barack Obama said at a parting press conference tonight (at about 11 to 11:30 p.m. local time, before leaving Denmark). Not so fast, argue a number of other negotiating blocs...like the G77.

Climate: China defends its reputation
Over the past few days, a number of national delegations – not least the United States’ – have criticized implicitly, if not explicitly, China’s unwillingness to accept binding limits on its greenhouse-gas emissions and the measurement of emissions by outside auditors. This morning, Chinese Premier Wen Jiabao addressed a plenary meeting of the United Nations climate-change conference – populated by more than 100 heads of heads of state – to make his case that China has embarked on an earnest step toward substantive climate protection.

Climate emissions mandates: What role China and India?
One major schism between negotiating blocs at the United Nations climate change meeting is over which nations should face a mandate to reduce their greenhouse-gas emissions. Just the industrial powers that have historically spewed most of the carbon dioxide responsible for today’s climate troubles? Or that group and the newly emerging industrial leaders – especially China, who for several years has reigned as the world’s greenhouse-gas king? The deadline for resolving this dilemma is ostensibly quite imminent. As in today.

Tiny Tuvalu could quash climate deal
Prime Minister Apisai Ielemia brags that his tiny 9-island state of Tuvalu is the world’s smallest independent country. Its 10,000 inhabitants live an average of 2 meters above sea level, which makes their homeland highly vulnerable to disappearing with even modest sea-level rise. With the nation’s survival so dependent on climate protection, he vowed today that Tuvalu will not sign onto any climate-change accord that does not require “legally-binding” language and programs aimed at ensuring global temperatures peak at “well below” 1.5 oC. That could effectively torpedo hopes for a climate accord tomorrow when the United Nations climate change meeting is slated to wrap up.
