United Nations Antonio Guterres has urged countries to implement disaster warning systems to protect people against extreme weather, saying no country is safe from the effects of global warming.

"Every one of the last ten years has been the hottest in history. Ocean heat is breaking records while decimating ecosystems. And no country is safe from fires, floods, storms and heatwaves," he told delegates at the UN World Meteorological Organisation's extraordinary conference in Geneva to mark its 75th year.

Guterres urged countries to mobilise funding to enable a global system of surveillance, known as Early Warning Systems.

"They give farmers the power to protect their crops and livestock. Enable families to evacuate safely. And protect entire communities from devastation," Guterres said.
