Obama likely to take on climate change during second term

China expects US President Barack Obama will give climate change more attention in his upcoming second term, top climate change negotiator Su Wei said ahead of the climate change talks in Doha, Qatar.

Increasing extreme weather events are threatening the world, and the recent catastrophic Hurricane Sandy is likely to profoundly influence US climate change policy, Su said.

"But it would be difficult for President Obama to make large adjustments during the final stage of his first term, so we expect more will happen in his second term," Su said.
