Humanity now faces an 80 percent chance that Earth's temperatures will at least temporarily exceed the key 1.5-degree Celsius mark during the next five years, the UN predicted Wednesday.
The 2015 Paris climate accords, which set the ambitious target of limiting the world to a temperature increase of 1.5 C over pre-industrial levels, meant to refer "to long-term temperature increases over decades, not over one to five years", the UN's World Meteorological Organization said.
