From his speech at the Poznan climate talks December ’08 full text here:

We must link poverty reduction with the sharp reduction of CO2 emissions, including reduced emissions from deforestation with reform of the clean development mechanism and adequate funding for adaptation that is essential and must be financed even though obviously mitigation and prevention are the primary task because without them adaptation would ultimately prove to be impossible.

… Our children have a right to hold us to a higher standard when the future of all human civilization is hanging in the balance. They deserve better, and politicians who sit on their hands and do nothing to confront the greatest challenge humankind has ever faced. This crisis does offer us the chance to experience what few generations have had the privilege of experiencing, a generational mission, a compelling moral purpose, a shared cause and the opportunity to put aside the pettiness and conflict of politics and narrower concerns to embrace a genuine moral generational mission. I believe that it is time between now and the gathering in Copenhagen 1 year from now for heads of state to become personally involved in meeting several times between Poznan and Copenhagen. I don’t think that they can stay disengaged from this process any longer.
