British Prime Minister Boris Johnson has told the United Nations General Assembly that humanity is approaching a "critical turning point" in the fight against global warming. He called for responsible action.
Johnson was speaking to world leaders on Wednesday ahead of the UN climate conference his country will host in November.
He said the Glasgow COP26 summit will be the turning point. He said, "We must show that we are capable of learning, maturing and finally taking responsibility for the destruction we are inflicting not just on our planet but upon ourselves."
He urged governments to limit the rise in temperatures to 1.5 degrees Celsius from pre-industrial levels. He also urged developed nations to stop coal-fired power generation by 2030 and developing countries to do so by 2040.
Johnson welcomed Chinese President Xi Jinping's announcement on Tuesday that China will not build any new coal-fired power stations abroad. He urged China to "phase out the domestic use of coal as well."
He referred to flooding, fires and other disasters caused by extreme weather. He said our grandchildren will know that this generation were warned but missed our cue and that "they will ask themselves what kind of people we were to be so selfish and so shortsighted."
