UN meeting calls for more climate effort

Participants in this year's United Nations climate change conference called for more ambitious pledges in reducing greenhouse gas emissions as the conference started on Monday in Madrid, Spain.

Carolina Schmidt, Chile's environment minister, said the conference needs to lay the groundwork for moving toward carbon neutral economies while being sensitive to the poorest and those most vulnerable to rising temperatures.

"Those who don't want to see it will be on the wrong side of history," said Schmidt, also chairwoman of the climate conference.
