The latest United Nations climate summit got off to an unusually emotional start when Yeb Sano, the head delegate from the Philippines, issued a tearful plea at the opening plenary.

With his country ravaged by Typhoon Haiyan — the kind of extreme weather that experts say is becoming more common due to climate change — Sano choked back tears as he announced he would fast in solidarity for his countrymen left without food.

Sano said on Nov. 11 he would refrain from eating during the conference unless important progress was made. Sano’s gesture has so far failed to trigger much of a change in the entrenched negotiations, and with talks expected to stretch into the weekend, he is still on his hunger strike.
