Thousands of delegates from nations and environment organizations from around the world have opened two weeks of United Nations climate talks meant to lay the groundwork for a new pact to fight global warming.

U.N. climate chief Christiana Figueres told the opening session on Monday that "it is time to go the extra mile" and guarantee greater climate security for the generations to come.

She said a "sobering reality" fact came in the form of Typhoon Haiyan, which took thousands of lives when it hit the eastern seaboard of the Philippines on Friday.

Scientists say you can't conclusively link a single storm to global warming. Also, the link between warming and hurricane activity is unclear. However, rising sea levels are expected to make low-lying nations more vulnerable to storm surges.

Results from the talks in Warsaw could be an indicator of the world's chances of reaching a deal in 2015.
