US, China aim to revive climate cooperation

US climate envoy John Kerry arrived in China yesterday, state media reported, to restart stalled talks between the world's two biggest emitters of planet-warming gases. Starting today, "China and the United States will have an in-depth exchange of views" on climate issues, state broadcaster CCTV said on Kerry's arrival in Beijing. Kerry's trip to China, where he will meet with his counterpart Xie Zhenhua, follows weeks of record-setting summer heat that scientists say is being exacerbated by climate change.
