Un Cop20

About 190 nations faced a crossroads on Friday on how boldly to fight global warming as United Nations talks in Lima went into overtime amid concerns that watered-down goals could undermine a UN climate summit in Paris next year.

Thousands of people marched in central Lima against the abuse of Earth's resources Wednesday, urging ministers haggling over a world climate deal to ensure a global switch to 100-percent clean energy by 2050.

Rich countries had by Tuesday pledged more than $10 billion in climate aid for poor economies in a major milestone for UN global warming talks in Lima, according to a tally compiled by AFP.
