DOHA, Qatar — During a year with a monster storm and scorching heat waves, Americans have experienced the kind of freakish weather that many scientists say will occur more often on a warming planet.
And as a re-elected president talks about global warming again, climate activists are cautiously optimistic that the U.S. will be more than a disinterested bystander when the U.N. climate talks resume Monday with a two-week conference in Qatar.
“I think there will be expectations from countries to hear a new voice from the United States," said Jennifer Morgan, director of the climate and energy program at the World Resources Institute in Washington.
The climate officials and environment ministers meeting in the Qatari capital of Doha will not come up with an answer to the global temperature rise that is already melting Arctic sea ice and permafrost, raising and acidifying the seas, and shifting rainfall patterns, which has an impact on floods and droughts.
