Mari Helena Castillo Mariscal, the deputy lead negotiator of Panama, scolded national and corporate leaders for setting the Earth on track for “a fatal 2.4 degrees warming,” referring to a United Nations forecast made this week, The Post’s Dan Zak reports. The country, which claims to have the youngest delegation of negotiators at an average age of 29, is channeling youth outrage over climate change. Mariscal called the target of keeping warming below 1.5 degrees Celsius “a necessity, a moral obligation, a lifeline.”
