No time to quarrel: Kerry warns of climate 'tragedy'

US Secretary of State John Kerry delivers a speech in Lima on December 11, 2014Developing nations must cut carbon emissions even if they feel it is unfair, US Secretary of State John Kerry said Thursday, warning of climate “tragedy” if quarrelling derails a global pact. “I know the discussions can be tense and decisions are difficult and I know how angry some people are about the predicament they’ve been put in by big nations that have benefitted from industrialization for a long period of time,” Kerry said in Lima, where tense negotiations were under way for a world climate pact. UN negotiators remain deeply divided on details of a deal to limit global warming to two degrees Celsius (3.6 degrees Fahrenheit) through curbing emissions of Earth-warming greenhouse gases. Developing nations say the West should bear a bigger burden, having polluted their way to wealth.
