China's climate leadership well demonstrated

In yet another warning of the increasingly dire climate change situation the world now is facing, UN Secretary-General Antonio Guterres said on Sunday that there is a danger global warming could pass the "point of no return".

"The point of no return is no longer over the horizon," Guterres told reporters in Madrid, the Spanish capital. "It is in sight and hurtling toward us."

He was speaking on Monday prior to the start of a two-week international climate conference, where delegates from nearly 200 countries are scheduled to finalize the rules governing the 2015 Paris climate accord, including how to create functioning international emissions trading systems, and compensate poor countries for losses they suffer from rising sea levels and other consequences of climate change.
