Last year was the hottest on earth since record-keeping began in 1880, scientists reported on Friday, underscoring warnings about the risks of runaway greenhouse gas emissions and undermining claims by climate change contrarians that global warming had somehow stopped.
.....“Climate change is perhaps the major challenge of our generation,” said Michael H. Freilich, director of earth sciences at NASA, one of the agencies that track global temperatures.....
....NASA and the other American agency that maintains long-term temperature records, the National Oceanic and Atmospheric Administration, issued separate data compilations on Friday that confirmed the 2014 record. A Japanese agency had released preliminary information in early January showing 2014 as the warmest year.
One more scientific group, in Britain, that curates the world’s temperature record is scheduled to report in the coming weeks.
