Envoys at United Nations global warming talks are considering whether to adopt a target forcarbon emissions around 2050 as they struggle to work toward a deal to limit climate change that they aim to agree on in 2015.
The delegates from about 190 nations meeting this week in Bonn are discussing whether they could tighten targets by adopting a worldwide goal for the middle of this century backed by interim measures proposed by national governments, said Alden Meyer, policy director at theUnion of Concerned Scientists, which is following the talks.
“The fear is countries would pick their own criteria to put their own plan in the best light,” Meyer said in a telephone interview.
The measures would feed into the agenda for the annual round of global warming involving environment ministers and heads of state starting in November in Warsaw. Meyer said he’s concerned the efforts fall short of goals to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit) from pre- industrial levels.
