Copenhagen: Agreement Reached, No Final Deal

The meeting is over, but no final legally binding treaty has been reached. At present there is no agreement which will ensure global temperatures do not exceed 2 degrees Celsius, considered to be the point at which dangerous climactic changes could occur
In a nutshell "The deal sets an end-January 2010 deadline for all nations to submit plans for curbs on emissions to the United Nations. A separate text proposes an end-2010 deadline for reporting back on - but dropped a plan to insist on a legally binding treaty."
