France urges more countries to promise emissions cuts ahead of UN climate talks in Paris

France is urging holdout countries to submit their pledges to curb greenhouse gas pollution ahead of a major U.N. climate conference in Paris.

A total of 146 nations accounting for 87 percent of global carbon emissions submitted their pledges by a U.N. deadline last week. French Foreign Minister Laurent Fabius, in a statement Sunday, pressed others to submit theirs "as soon as possible."

The Nov. 30-Dec. 11 conference is aiming for an ambitious deal to keep the rise in worldwide temperatures below 2 degrees C (4 F) this century.

Fabius said the pledges so far would slow global warming to a rise of less than 3 degrees C — better than "the most pessimistic scenarios" but not enough to avoid irreversible impact to the Earth's climate system.
