Developed nations' role at issue in climate meeting

Developed countries were called upon to honor their pledges of financial support for developing countries in tackling climate change at the opening of the annual UN climate change conference on Monday in Katowice, Poland.

The 24th Conference of Parties to the United Nations Framework Convention on Climate Change, or COP 24, is tasked with finalizing the detailed implementation guidelines for the landmark 2015 Paris climate change agreement.

"This meeting is the most important gathering on climate change since the Paris agreement was signed," said United Nations Secretary-General Antonio Guterres, addressing the opening ceremony.
