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.
