U.N.: Governments must commit to funding action on climate change WARSAW, Poland, Nov. 15 (UPI) -- World governments must make concrete funding commitments to tackle the effects of climate change, a U.N. expert has told a climate conference in Warsaw. "World leaders have a crucial opportunity in Warsaw to secure the foundations of a strong, fair and ambitious framework, which is essential to minimize the effects of climate change," the Independent Expert on Human Rights and International Solidarity, Virginia Dandan, told negotiators from more than 190 countries taking part in the U.N. Climate Change Conference. During the two-week conference, delegates will try to forge an agreement on a legally binding climate change treaty to be adopted by 2015 and enter force by 2020, a U.N. release said Friday. Conference discussions should be grounded on the principle of international solidarity, Dandan said, and must not become stalled over the issue of compensation for the effects of climate change. "Time is too short and the consequences too great to risk these negotiations becoming caught in entrenched political positions and economic self-interest," she said. "Warsaw is the moment for genuine collaboration among states to establish safeguards for minimizing the adverse effects of climate change on the basic human rights and fundamental freedoms of all peoples, especially those in the most vulnerable countries," she said.
