UN Chief Blames Rich for Global Warming Print article Send a Tip from AP 5 Dec 2012 post a comment (AP) AP Interview: UN chief blames rich for warming DOHA, Qatar The U.N. chief says rich countries are to blame for global warming and should take the lead in forging a worldwide climate pact by 2015. Ban Ki-moon says it's a deadline that "must be met." Ban told The Associated Press on the sidelines of U.N. climate talks in Qatar on Wednesday that "it's only fair and reasonable that the developed world should bear most of the responsibility" in fighting climate change. Ban says the "phenomenon has been caused by the industrialization of the developed world," whose factories released carbon dioxide into the atmosphere long before the climate effects were known. Ban is in Doha to push the negotiations to "accelerate the process" of shifting the world to clean energy pathways and helping the most vulnerable countries adapt to global warming.
