Christiana Figueres, Executive Secretary of the UN Climate Secretariat, visited the Living on Earth studios on her way from UMass Boston to international negotiations in Bonn, Germany. The Bonn session is one of many leading up to a meeting in Paris, France in 2015 when nations have pledged to sign a binding agreement to curb global warming gases. Secretary Figueres told host Steve Curwood she’s sure there will be a global deal because there is no other choice, and it’s in every country’s interest.
