6:40 pm Copenhagen time -- The United Nations climate group has officially extended COP15 into Saturday. World leaders and negotiating teams have been in meetings since midday, still attempting to make a breakthrough on a "political accord" of common understandings about a new climate change agreement. 

Call it COP15.1

Among the many juicy, unconfirmed rumors and tweets from journalists and adocacy group staffers [[and their ratings on the Truth-o-meter]]:

• The delegations are up to a sixth version of a draft "Copenhagen accord." The accord is "political," that is, a statement of agreed-upon principles, not the formal successor to the Kyoto accord.  [[Truth-o-meter rating: high]]
• Targets and timetables have wandered as each draft has been leaked to press. [[Truth-o-meter rating: high]]
• The latest mentions  a target of keeping mean global temperature rise at or below 1.5 degrees Centigrade, and drops a 2010 deadline for a final treaty. [[Truth-o-meter rating: medium.  This may actually refer to the fourth leaked draft.]]
• The discussions are now boiling down to arguments about procedure: majority vote vs. consensus. Total meltdown looming.  [[Truth-o-meter rating: medium-high]]
• Obama is locked in a second meeting with Premier Wen at this very moment. [[Truth-o-meter rating: medium-high]] 
• President Obama and Premier Wen will have a bilateral talks (i.e., meet alone) at 7:00 pm Copenhagen time -- in about a half hour. [[Truth-o-meter rating: low]]
• Premier Wen is infuriated by President Obama's speech and has already left the building. [[Truth-o-meter rating: rock bottom]]
