"The United States resisted pledging steeper cuts in greenhouse gas emissions by 2020 on Monday despite calls by poor nations at the start of a U.N conference for tougher action to avert storms, droughts and rising seas."
"About 200 nations met for annual U.N. talks on global warming with little prospect of a breakthrough and recriminations over how to keep alive hopes of a new, global U.N. deal to fight climate change meant to start up in 2020.

U.S. deputy climate envoy Jonathan Pershing said that President Barack Obama was sticking to his 2009 goal of cutting emissions by 17 percent below 2005 levels by 2020. That target was not approved by the U.S. Senate."
