This is still the challenge Parties to the UNFCCC face at COP-17 in Durban this year.

Over the last twenty years GCI has made an effort - arguably unequalled by any agency in the entire UNFCCC-process - to elucidate, answer and communicate answers to this point: - what rates of C&C are required for UNFCCC-compliance?
The effort has been made to help [and not prescribe to] negotiators at the UNFCCC on how they might yet come to an effective global agreement. Below are a few examples of GCI's effort to this ranging over the last fifteen years.
Here is a recent example from COP-15 Copenhagen December 2009: -
As with the 'Berlin Wall', the 'Climate-Firewall' can yet come down.
'Climate-detente' possible
at COP-17 with negotiated rates of C&C.
