Nohopenhagen: 2335 update

The fat lady hasn't sung yet, the farcical bollocks that was Nohopenhagen appears over without resolution (thank God) but nobody is admitting it.

2145 Mr Obama's comments to White House press pack are coming over on the wires and it's a bit confusing.

He calls it a "meaningful and unprecendented breakthrough", but admits not enough progress was made. He says that the agreement will not be legally binding on the US (or, presumably, anyone else) but America would stick to its promises on carbon emissions.

A legally binding agreement will be "very hard" and "take some time".
