The head of the United Nations called Monday for scientists to serve up “cold, hard facts” to push governments into making policies that curb climate change before a key global warming threshold is passed.
His comments came as experts and officials from around the world gathered for a week-long meeting in the Swiss Alpine town of Interlaken to finalize the last of seven reports issued by the global body's panel of top scientists since the Paris climate accord was forged in 2015.
