Addis Ababa, Ethiopia - Norwegian Prime Minister Jens  Stoltenberg said on Wednesday the world would likely not be able to  reach agreement on climate change-related actions without first striking  a deal on climate financing. Addressing the Seventh African Development  Forum (ADF-VII), which is dedicated to climate change, he said it  would, however, be 'challenging' for developed countries to honour a  pledge made at Copenhagen last year to raise US$100 billion annually to  finance climate adaptation and mitigation efforts in developing  countries.
